What are the main ingredients of Fireproof Coating Flame Retardant?
Fireproof Coating Flame Retardant is a refractory coating and flame retardant, and is responsible for preventing flames from burning and ensuring the safety of buildings. Its main ingredients are mostly as follows:
One is phosphorus-based compounds, such as ammonium phosphate salts, phosphate esters and red phosphorus. Phosphorus flame retardant, carbonation reaction occurs in case of fire, forming a carbon layer, blocking heat sources and oxygen from the outside, making it difficult to support combustion.
Two is halogen-based compounds, especially bromine and chlorine compounds. Its mechanism is decomposition at high temperature, releasing halogen free radicals, cutting off the chain reaction generated by combustion, but its smoke and residues or harmful substances are now mostly eliminated or reduced.
Third, aluminum hydroxide and magnesium hydroxide belong to metal hydroxides. When decomposed by heat, a large amount of water is released, diluting the temperature of the combustion zone and combustible gases, and synthesizing non-toxic by-products, which is safe and environmentally friendly. Common in all kinds of fire-resistant coatings on interior and exterior walls.
Fourth, expansion-type ingredients, such as expandable graphite, carbonized polymers, etc. The flame contact is instantaneous, and it expands rapidly, forming a dense thermal insulation protective layer, which can insulate heat and oxygen, and form a flame retardant barrier with building substrates. It is quite common in modern new fireproof materials.
Fifth, polymer resins, such as epoxy, acrylic acid, polyurethane, etc. It is not only the carrier of the coating, but also can wrap the above inorganic and organic flame retardants to enhance its adhesion and construction convenience Excellent resin can reconcile the combination between the components, improve the overall weathering resistance and fire protection efficiency of the coating.
And often supplemented with additives, dispersants, curing agents, etc., synergistic effect. Today's technology is developed, or a variety of flame retardant mechanisms are synthesized to complement each other, and the effect is more and more significant. In the end, safety, environmental protection, weather resistance, and simple process are its main trends. To sum up, although Fireproof Coating Flame Retardant has many components, it takes its meaning as a synergistic effect, common fire control, and permanent building safety.
How to use Fireproof Coating Flame Retardant?
Fireproof Coating Flame Retardant, flame-proof coating, made on the surface of the object to prevent the spread of fire and ensure safety. The method of use needs to be followed by rules and regulations, detailed and detailed. The materiality of the object must be checked first. If it is wood, gold, stone, cloth and plastic, etc., it can be applied. Before operation, the surface of the coated object must be clean and free of dust, grease and mildew. It can be wiped with a clean cloth, or lightly ground with fine sandpaper to make it smooth and smooth and easy to adhere. In case of pores or cracks, it should be filled with cement or suitable materials.
Before the coating is used, it needs to be fully stirred to make its texture uniform and not agglomerate. When applying, it varies according to the appliance or method. If you use a brush, you can use goat hair or a synthetic brush, dip it in paint, apply it evenly, and the action will be gentle and not omitted. For sprayers, you must be equipped with a special spray gun, with moderate pressure, from top to bottom or from one side to the other, spraying freely and covering a wide area. It is also most convenient to apply it with a roller in a flat and wide place. Each time you apply, the thickness is moderate, not too thick or thin. Conventional can be applied one to two times, and the interval must be waited for it to dry before it can be used for the second time. If it dries naturally, it will take about a few hours. If you use a fan or heating, you may be able to dry quickly. Do not encounter rain, snow and humidity, and it is better to use a clear and bright day.
When the coating is completed, check that the surface is smooth and clean, without bulging, hanging, and holes. If there is any omission, add the same method. After drying, it has excellent flame retardant effect. If applied indoors and outdoors, pay attention to the instructions of the ingredients. Others follow their guidelines and should not be confused. Store the remaining materials in a cool and dry place, away from fire sources. Don't let children touch it, and you can't eat it.
To sum up, the application of fireproof coatings must be prepared with a clean foundation, uniform application, suitable thickness and meticulous nourishment. If you abide by this method, the coated material will be as strong as iron and not afraid of flames.
What materials are Fireproof Coating Flame Retardants suitable for?
Fireproof Coating Flame Retardant is made of technology in this world. It is used for flame retardant and fireproof, and fits the surface of various materials. If you need it for construction, wood is the first, and the flammability is clearly visible. If you apply this flame retardant layer, the fire will be difficult to erode. Another example is metal. Although it is self-non-flammable, it is easy to lose toughness at high temperatures. If it is coated with flame retardant paint, it can improve the fire resistance and is often used in steel structures. Stone is inherently non-flammable, but its surface is coated with this coating, which can increase protection and reduce high temperature exfoliation. As for concrete, it can be applied with flame retardant to delay heat transfer and protect its structural safety.
Looking at interior decoration, commonly used cloth, paper, leather, and plastic materials are all prone to ignition. Applying this fire retardant can greatly reduce the burning rate and prolong the rescue opportunity. Furniture utensils, window curtains, and curtain tents can be applied. The shell of its electromechanical equipment is mostly plastic and composite boards can also be coated with load. The outside of the cable is rubber, which melts in case of fire. If flame retardant liquid is applied, it can ensure the safety of the line.
Shipping equipment, such as ships and airplanes, have flame retardant requirements for the materials inside. Flame retardant coating on its wood, iron, cloth, and plastic surfaces is obviously effective and reduces the risk of fire. Carriages, rail vehicles, and subway tunnels are all used to increase stability.
In chemical warehousing, storage tanks and pipes are mostly made of metals. If flame retardant coatings are prepared, temperature transfer can be delayed in case of fire. There are also special glass, embellished with flame retardant agents, which can also be kept intact for a short time. In today's high-rise buildings, flame retardant coatings are their safety protection. Roofs, walls, beams and columns are all applicable.
It is important that Fireproof Coating Flame Retardant covers a wide range of surfaces, including wood, metal, stone, concrete, plastic, fiber, glass, and rubber. All can apply art based on materials to exert the power of fire prevention, so that all kinds of things can be safe when flames are difficult to wreak havoc. However, the method of application and the appropriate ingredients need to be considered for school entrance examination, combined with the characteristics of various surfaces, and then get their full power.
How long does Fireproof Coating Flame Retardant last?
Fireproof Coating Flame Retardant is a new paint used in this world to prevent fire. It is strong and heat-resistant. In case of fire, it can stop the spread of flames and slow down the burning of objects. It is a weapon for disaster prevention. When its efficacy lasts, it is necessary to consider its quality, depending on its use, and balance the similarities and differences of its environment.
The coating is originally synthesized from non-flammable materials, such as aluminum hydroxide, phosphate esters, chlorine compounds, etc., supplemented by polymer, so that it adheres to the surface of wood, steel structures, and fabrics. When it is flamed, the coating film carbonizes, isolates oxygen and flames, prevents internal heat generation, and relieves the volatilization of combustibles, which prevents combustion. The advantages and disadvantages of its effectiveness are mainly determined by the advance and retreat of the formula, the uniform thickness, the coarse construction, and the nature of the base applied. If the ratio is appropriate and the surface coating is comprehensive, it can delay the spread of the fire in the event of a hot fire, and protect the structure for about 30 minutes to several hours.
However, the world is impermanent, the passage of time, external wind and rain erosion, and sunlight frost and dew are enough to damage its function. Over time, the coating may crack and peel off, or be contaminated and attached, resulting in increasingly weakened fire protection performance. For example, common building codes require re-inspection and repair every few loads, or re-application of paint to ensure its fire resistance. If it is indoors, the environment is moderate, and the external force is slightly damaged, its fire protection effect may be more than ten years; if it is outdoors, with wind and rain and frequent dust attacks, its lifespan is as short as five years.
As for the fire scene, the Fireproof Coating Flame Retardant can maintain the fire protection function for a long time, depending on the heat and the size of the fire. If the flame is sudden and the temperature is very high, its ability and time to contain the fire are also limited. However, the general construction paint can often last for 30 minutes or even two hours, so that people can be evacuated and property can not be destroyed in an instant.
Overall, Fireproof Coating Flame Retardant fireproof coating, although the process is changing with each passing day, its effectiveness will eventually wear out at any time, and it must be well maintained and checked on time to ensure its long-term fireproof effect and protect peace.
How environmentally friendly and safe is Fireproof Coating Flame Retardant?
Fireproof Coating Flame Retardant, translated as fireproof coatings and flame retardants, is widely used in many fields such as construction, transportation, electronics, etc. In terms of its environmental protection and safety, it is a matter of great concern in the world, and it is necessary to carefully distinguish the cause and the end.
The system of fireproof coatings used to use bromine and chlorine containing organic compounds in the past. Although it has excellent flame retardant effect, it is easy to precipitate harmful gases such as dioxins and furans at high temperatures, which are highly toxic, vulnerable to human and animal damage, and also cause environmental load. Furthermore, some traditional flame retardants can penetrate into soil and water bodies, accumulate in organisms, and cause biological toxicity. In addition, brominated flame retardants have stable molecular structures, are difficult to degrade, and have strong migration. They are distributed between heaven and earth for a long time, which has far-reaching impact.
However, with the development of science and technology, today's flame retardants are becoming more environmentally friendly, and mainstream new products are mostly halogen-free and non-toxic. Common green flame retardant materials include aluminum hydroxide, magnesium hydroxide, phosphorus and nitrogen-based compounds. When such materials are thermally decomposed, they do not produce toxic gases, can neutralize and burn heat, release moisture, dilute oxygen concentration, and effectively inhibit the spread of fire. Most of their residues are harmless, can be safely disposed of, and are not a burden on ecology.
In addition to environmental protection, human safety must be discussed. High-quality environmentally friendly flame retardant coatings are strictly monitored for the risk of When applied indoors, it can greatly reduce the release of harmful substances such as carbon monoxide and hydrogen cyanide in fires, and protect human life. Many products have been certified for international environmental protection and safety, making them more reliable to use.
The only thing is that although green is advocated at the moment, the market is mixed, and some inferior products may still contain trace amounts of harmful ingredients. Purchase with caution and test their performance and proof. It can be used rationally and operated according to specifications to maximize its advantages of safety and environmental protection.
In summary, if Fireproof Coating Flame Retardant adopts a new environmentally friendly formula and is produced and used according to specifications, it can not only prevent fire and rescue, but also do not harm the environment and human safety. It can be described as a good product that benefits the country and the people.
