    General Information
    Historical Development
    Steel structures have been introduced since modern Western technology. Because they are strong and light, they are widely used in the construction of palaces, temples and bridges. However, due to fire, the flames burn fiercely, and the strength of the steel body is easy to lose, and the hidden dangers will not be removed. In the 20th century, engineers in various countries began to study flame barriers. At first, plaster and mortar were applied to the surface, and then polymer compounds were applied to the steel body. Since then, fireproof coatings have been gradually perfected, which can adapt to local conditions and resist high temperatures, especially in high-rise buildings and warehouses. In recent years, nanotechnology has been involved, and in parallel with the concept of green environmental protection, if smokeless, non-toxic and durable products have come out one after another. From ancient times to the present, skills have been replaced, safety and practicality have been given equal importance, and fire protection has become an indispensable material for modern architecture.
    Product Overview
    Fireproof coatings for steel structures are made in response to the needs of building safety. The material is fine, coated on steel bones, and expands when heated in case of fire, turning into inert foam, isolating flame invasion, and effectively delaying the temperature rise of steel structures. It can protect the stability of the structure and reduce fire damage. It is suitable for high-rise factories and bridge storage.

It is suitable for the protection of steel frame beams and columns in factories, warehouses, high-rise buildings, etc., with clear signs, batch numbers, production dates and valid periods.
    Preparation Method
    Take kaolin, aluminum hydroxide, ammonium phosphate, etc. as raw materials, and add high temperature resistant organic resins and flame retardant additives. First, each raw material is finely ground in proportion, mixed in a kettle with moderate temperature, and stirred slowly to make a uniform slurry. Next, slow injection of catalysts such as benzoyl peroxide promotes resin polymerization, and complexes with the inorganic component to form a dense network structure. The temperature rise is controlled at 80 to 100 degrees Celsius to inhibit side reactions. During the process, ammonium phosphate decomposes when heated, and phosphorus complexes with aluminum oxide to form a flame retardant layer, which blocks heat transfer; and then kaolin synergistically enhances the densification of the coating. Finally, the material is cooled and discharged, and it is ground and filtered and encapsulated to obtain a fire-resistant coating for steel structure. Its reaction catalysis relies on peroxide radicals to initiate chain polymerization, and the synergistic additives stabilize the film layer, effectively improving the flame retardant performance, and are so complete.
    Chemical Reactions & Modifications
    The preparation of steel structure fireproof materials requires chemical reaction and modification to achieve high efficiency. Start with polymer resin as the base, supplemented by phosphorus, nitrogen and other flame retardant components, through bulk reaction or graft modification, resulting in the integration of flame retardant groups between molecular chains to enhance the material's resistance to flame. In case of flame attack, the surface layer of phosphorus and nitrogen reacts with high polymers to generate an expanded carbon layer, which is thermally isolated and prevents temperature rise. Or add nano-clay, hydroxyalumina and other fine fillers, which are uniformly dispersed in the matrix after surface modification to promote secondary reactions during inflammation, synergistically absorb heat and release water, inhibit thermal decomposition and slow down the escape of harmful gases. It is through chemical modification and reaction to improve the performance of the fireproof coating, and keep the steel structure peaceful in times of fire.
    Synonyms & Product Names
    Steel structure fire retardant coatings are called various by the market, or steel structure fire retardant coatings, also known as steel frame fire retardant coatings, and steel bone flame retardant powders are all such things. The trade names are as numerous as stars, and they are called "steel shield fire retardant", or "Hengan flame retardant", or "golden shield coating", which varies with the meaning of the manufacturer. Its synonyms are mostly found in technical literature, such as "steel structure fire retardant heat insulation coating", "steel fire retardant coat", "structural flame retardant protective layer" and "steel structure flame-proof film", which vary slightly depending on the scope. However, their essence is to prevent the spread of flames and strengthen the fire resistance of steel bodies. They are all used in high-rise factories, and all have this function. Merchants list prices, each with the formula and function names they advocate, but in the end it is the urgent need for fire protection of steel structures. The purpose is not easy. Although the names are different, the uses are common.
    Safety & Operational Standards
    Fireproof coatings for steel structures are used for disaster prevention, and the most expensive thing is to get the law. Coating matters, the first priority is safety, and special personnel handle it. Its clothes should be neat, clothes, hats and gloves, mouth and nose must be covered, and micro-prevention. The appliances are clean, mixed evenly, and do not allow impurities to invade; the site is spacious, well ventilated, fire sources are far away, electrical protection, and no negligence is allowed. Storage is well-protected, cool and protected from light, waterproof and moisture-proof, fireworks are strictly prohibited, and they are stored by category. Index according to regulations. Unsealing is imminent, check the label, production date, quality assurance period, expiration is useless, and do not be greedy for small and big.
    Before operation, read the instructions carefully, know the taboos, and strictly follow the factory rules. When blending, do not use your hands, weigh accurately, the solvent ratio, add in sequence, stir in an orderly manner, do not be impatient. Apply the construction, the thickness is uniform, and the layers are to be dried before stacking. Work at height, wear seat belts, set up ladders firmly, and patrol each other. Wind and rain, suspend operations. After application, clean up the leftovers, save materials, and return to a tidy place.
    In case of leakage, quickly collect the adsorbent, discard it properly, and do not drain the water. If there is any contact with the skin at the mouth and eye, rinse it with water first. If there is still discomfort, ask for medical assistance. If you are not careful with the fire, you should use dry powder and sand to extinguish it, and do not splash it with water. After everything is over, wash your hands, chat about nothing, and return safely. This is the key to safety, the key to operation, and it is safe to practice it without slack.
    Application Area
    Steel structure fire retardant coating is widely used in high-rise buildings, factories and warehouses, airport stations, bridges and tunnels and many other fields. It is strong but non-flammable, and will not burn in case of fire. It can delay the heating of steel and ensure the safety of building structures. In today's cities, buildings are numerous, and steel structures are their bones. If there is a fire, it will be damaged very quickly, and the way of protection cannot be ignored. Therefore, this coating is used to cover beams, frames, and stairs. Its effect can not only extend the fire resistance limit of steel, but also facilitate later maintenance and aesthetics. Chemical, electric power, petroleum, marine and other projects also rely on this fireproof device to prevent accidents and protect lives and property. The reason why steel structure fire retardant coatings are reused in Sri Lanka is that they are simple to apply, strong to cooperate, and durable, making them an indispensable new material for modern architecture.
    Research & Development
    The research and development of fire-resistant and flame-retardant products for steel structures is also necessary for the safety of modern buildings. The ancient houses were made of wood, which caused frequent fires. Today, steel is used to replace them, which is stronger and more stable, and there is a worry of collapse in case of high temperature. It is the inspiration of future generations to study fire-resistant coatings, which have the effect of protecting steel bodies and delaying heating. However, the initial technology is simple, the coating is heavy, and the construction is difficult, making it difficult to adapt to the needs of high-rise giant structures. Times change, scientists introduce nanomaterials and new binders, which make the products as thin as cicada wings and increase flame retardancy. Researchers also take green environmental protection as the case, reducing the escape of harmful volatiles and promoting sustainable development. The detection methods are increasingly perfect, the international standards are in line, the experiments are repeated, the data are detailed, and the thickness and adhesion are equally important. Today's refractory products are transported to bridges, factories and buildings to ensure the peace of all living beings. It is the way of research and development, the future is opened up, continuous progress is made, perfection is perfect, and tens of thousands of people rely on it.
    Toxicity Research
    Fireproof coatings for steel structures are commonly used in modern industrial institutions to prevent fires and ensure building safety. However, its ingredients mostly contain flame retardants and additives, and their properties may be dangerous. Taste animal experiments to investigate its toxicity. It contains elements such as bromine, phosphorus, antimony, etc., which are ingested into the body or inhaled into its dust. In light cases, it causes throat discomfort, and in severe cases, it hurts the lungs. Or put the test drug in the body of mice and observe their physiological reactions. At first, you see agitation, followed by fatigue; even at high doses, you can observe changes in the organs, and occasionally damage to the liver and kidneys. However, with normal exposure, the dose is very small, and the symptoms are very rare. Detection in this world has not yet seen the fact that it causes cancer; if it accumulates for a long time, it cannot be completely sparse Workers must wear masks and gloves when applying, and have good ventilation before they can be poisoned. Overall, the toxicity of steel structure fireproof coatings can be controlled by the process, and they can be used with caution.
    Future Prospects
    Fireproof materials for steel structures are necessary for contemporary building safety. Looking at technology, materials science is becoming more and more advanced, and fire protection products are also advancing with the times. Future research and development will rely on nanotechnology and new composite ingredients to improve its flame retardant performance, prolong the fire resistance period, and reduce the load of its own weight. Its manufacturing process should be more green and environmentally friendly, reducing the harm to the human body and the environment. In terms of application, it should be widely involved in high-rise buildings, industrial plants and other important places, adapting to diverse climates and complex environments. And with the help of artificial intelligence and big data, the monitoring and maintenance system will also be intelligent, real-time early warning and even remote control are expected. Therefore, the future of steel structure fireproof materials must move towards high efficiency, safety, and intelligence, laying a solid foundation for the long-term stability of human architecture.

    What is the Main Fire Protection Principle of Steel Structure Fire Retardant?
    Fireproof coatings for steel structures are used to contain the raging flames and protect the steel from suddenly losing its load-bearing power. Covering steel is inherently strong, but when it encounters a hot topic, it is soft. When the temperature reaches 500 degrees, it will buckle and collapse. There is no guarantee. As soon as the fire arrives, it will be very harmful. All buildings, factories, and those who rely on their support are in danger. It is based on ancient and modern craftsmen who think hard and make fireproof agents in order to delay heat transfer and protect steel bones.
    Fireproof coatings for steel structures have two reasons. First, the paint expands and foams when heated, making the honeycomb porous and blocking flame heat. This bubble-like layer is large, with numerous micropores, and it is especially difficult for heat to pass through. The flame burns the steel body, and the bubble layer is first exposed. The heat conduction inside and outside is very different, and the heat is sluggish, so that the steel bone is temporarily safe. Second, the coating is inherently resistant to high temperature, and has the characteristics of refractory combustion and heat dissipation. It is oxidized, dehydrated and even decomposed, seizing the energy of fire, and consuming heat to protect itself. Even if the flame burns, it can be unloaded over time. If the thickness is appropriate, it can provide an opportunity for steel parts to escape, and the structure has ample room for rescue.
    However, fireproof coatings have different materials. Either organic or inorganic, the quality is different and the effect is also different. Organic ones contain mostly expanded materials, which interact with fire and expand rapidly to generate foam heat resistance; inorganic ones have solid heat insulation, although there is no expansion, their heat transfer is more durable. The combination of various materials is gradually improved, resulting in double the safety of steel structures. However, the thickness of the coating and the uniform rank of the coating are also the key points of fire protection. If the operation is improper, its work will be wasted.
    The principle of fire prevention is to prevent fire by blocking fire and building a shell outside the surface, so that the heat cannot suddenly reach the steel body. Even if the building is in danger, relying on this thin layer of several inches is the important defense of modern engineering. Prepare this wonderful agent, steel bones like armor, although the fire is blazing, you have to deal with it calmly. Protecting people's lives and preserving property is actually the key to maintaining the stability of your family and country. Such a fire prevention principle is still in this world, and it is not easy for thousands of years.
    What is the Temperature Range of Steel Structure Fire Retardant?
    Fireproof coatings for steel structures are one of the barriers to delay the spread of fire and protect steel structures. They have a wide range of uses, and their applicable temperature range is also very important. Looking at the steel structure fireproof coatings in use today, they are generally divided according to their performance and grade, and cover thick coating type, thin coating type, and ultra-thin type. However, its temperature resistance is extremely high, which is related to the formulation and design of the coating, and is generally used between 100 degrees and 600 degrees Celsius. Temperatures below normal temperature will not deteriorate the fireproof coating. High temperatures can reach five or six hundred degrees, and the coating can still hinder heat transfer and preserve the internal force of steel parts. In case of flames, the temperature rises to around 600 degrees, and the steel is at risk of losing its structural strength. Fireproof coatings can maintain their carrying capacity at critical moments.
    When a steel structure encounters fire, the temperature rises sharply. If there is no protection, the fire resistance of the steel will drop sharply, and the steel will lose part of its bearing capacity at 150 degrees Celsius, which will become more dangerous when it reaches more than 300 or 400 degrees. Today's fireproof coatings are specially designed to resist interference based on the principle of thermal expansion or heat insulation. Taking the expansion type as an example, the coating expands when heated, forming a thick foam-like carbon layer, which is difficult to penetrate by heat, and the temperature rise of the inner steel is slow. Its applicable temperature is mostly between minus 20 and plus 600 degrees Celsius. As for the non-expansion type or the composite type, the temperature range is also slightly different, but generally not from the above range. Each has a ratio, which is suitable for the needs of different industrial and civil buildings.
    However, the efficiency of the coating depends on the thickness, uniformity, adhesion and supporting environment of the construction. If it is not properly operated, although it is applied to the steel watch, the temperature resistance is not enough. It is advisable to follow the specifications, choose regular products, and identify their inspection qualified reports. Looking at today's steel structure fireproof coatings, the applicable temperature range is usually between minus 20 and 600 degrees Celsius. In case of special projects, it can be adjusted according to needs, but it must follow the technical specifications and do not change it. In this way, the steel structure must be kept safe and the building is also completely solid.
    What are the Construction Methods of Steel Structure Fire Retardant?
    Fire prevention is the most important thing for building on behalf of others. Construction methods are often the same, and they can be used in a good way. Here is a brief description of the method. Let's test it.
    First of all, the method of fire prevention is commonly used. Fireproof materials are well-prepared, and they are all suitable for the surface. The thickness depends on the requirements. This method is convenient to apply, the efficiency is high, and the surface should be large. Only when the surface is dry and solid, and the surface is added, it will be effective. In case of poor or damp on the construction site, it will be slightly stifled.
    Secondly, the brush method is also advisable. Dip the material with a brush, and apply it to the material, which needs to be added repeatedly to make it dense. This method is thoughtful, and it is suitable for the parts, or the edges and corners of the pieces. However, the process is complicated, requires a lot of manpower, and consumes a lot of money.
    There is also a wrapping method, which is made of gypsum board, refractory board or pearl board, cut and closed, wrapped on the board, and sealed with bolts. This method is reliable in fire protection, effective, and occupies a lot of space, and the material and safety are especially careful.
    Near those still have the use of self-cleaning machinery, which can save manpower, increase uniformity, but it is not inexpensive to install, and it is not easy to operate.
    The cost of each method depends on the discretion. Generally, the construction is more used or brushed; high-quality and large-scale, important applications, or need to be legal to achieve perfection. All methods used require a clear surface of the material to ensure a firm adhesion and flame retardant performance. In this way, it can be safe from fires for a long time and ensure the safety of construction personnel.
    How is the Environmental Performance of Steel Structure Fire Retardant?
    Fireproof coatings for steel structures are also relied on by ancient and modern buildings. Its environmental protection performance is actually the gist of contemporary craftsmanship. The reasons for this are described below.
    Fireproof coatings for steel structures are mostly made of inorganic and organic composites, and do not contain harmful solvents or heavy metals, so they do not cause major ecological pollution. Its production method is excellent, and the feeding material is exquisite. It often selects ingredients that are non-toxic and harmless to the human body and the environment. When used, the smell is light, and it is not easy to cause volatile organic pollution. After it hardens, the layer is dense and stable like a rock. It is not easy to analyze harmful substances during wind and rain erosion, and keeps the place of work and life clean and safe.
    During the preparation process, the manufacturer uses more recycling methods, uses less energy-consuming equipment, and saves energy and reduces emissions. Products put on the market have mostly obtained environmental protection certifications or obtained green building materials labels, which proves that their production and use are appropriate. If the residues after use are properly recycled and disposed of in a standardized manner, they will not bring hidden dangers to soil and water bodies. Some coatings are more degradable and recyclable, showing the principle of ecological cycle.
    In addition to fire prevention, they are more weather-resistant and anti-corrosion, do not need repeated maintenance, and save resources. Compared with traditional oil-based coatings, they reduce harmful gas emissions and reduce the burden on the atmosphere. Since the promotion, the practice of green building concepts has contributed to the improvement of engineering quality and livability.
    In summary, steel structure fire retardant coatings have excellent environmental protection performance, not only maintaining building safety, but also conforming to green development. Whether it is production, use or disposal, they are all environmentally friendly and are an indispensable material for modern architecture. If applied according to local conditions and regulations, it can turn harm into benefit, benefit everyone, and protect me and clean the world.
    What are the Certification Standards for Steel Structure Fire Retardants?
    Fireproof coatings for steel structures are the essence of modern building fire protection, and there are many regulations for their certification standards. Among them, the most famous ones are the Chinese national standards "Technical Specifications for the Application of Fireproof Coatings for Steel Structures" (GB14907), "Fireproof Coatings for Steel Structures for Buildings" (GB/T9978), as well as European standards EN13381, American standards such as ASTM E119, etc. All steel structure fireproof coatings should be inspected by the above standards before they can be applied to large public facilities and industrial plants.
    Test content, the first fire resistance limit. According to its standards, the steel structure needs to be coated under high temperature, and the special furnace body should be coordinated to simulate the actual fire situation. Only those whose structures can maintain the bearing capacity within the specified time limit can be judged as qualified. Second, the coating thickness, bonding strength, anti-peeling, etc., all have clear limits to ensure that the coating is not easy to fall off during fires and can continue to withstand high temperatures.
    The material composition limit is also important for review. Fireproof coatings are mostly inorganic, expansive or composite materials, which need to be non-toxic and harmless gas escape to protect the health of the human body and the environment. In the test method, custom samples are often used, and flames are placed to bake or exposed to high temperature to test their physical and chemical properties. Whether they pass or not is recorded in the test report, notified to the relevant competent authority, and the certificate can only be issued after review.
    The European EN13381 standard formulates various types of coatings fire performance evaluation methods for different structural types, so that the standards tend to be scientific and complete. Another example is ASTM E119 in the United States, which focuses on the testing of components in the overall system state to ensure high reliability in practical applications. Although countries have similarities and differences, the general purpose is to keep structural protection and life assurance as the norm.
    To sum up, the certification of fireproof coatings for steel structures is complicated and rigorous. Those who apply it to important places must rely on the national standard, European standard, and American standard, and go through several steps of testing, review, and certification before they can be justifiably applied to buildings. Therefore, from this perspective, fire protection is the cornerstone of the structure, and it cannot be ignored.
