What are the main ingredients of Flame Retardant Paste?
Flame Retardant Paste, also known as flame retardant paste, was created by scientists in today's world to prevent fire and flame. Its ingredients are diverse, and can be divided into three categories: main agent, auxiliary agent and solvent. The main agent is phosphorus-based flame retardants, such as red phosphorus, ammonium phosphate salt, or phosphate ester preparations. Such substances decompose and release phosphoric acid at high temperatures, which can form a carbonized film on the surface of combustible materials to isolate air and cut off the three elements of combustion. There are also inorganic fillers such as aluminum hydroxide and magnesium hydroxide, which can decompose and release water vapor when heated, absorb heat, cool down and slow down, and do not generate harmful gases. The second solvent is commonly used water or alcohol, and sometimes mixed with polymer solutions, such as polyvinyl alcohol and acrylic acid emulsions, to prepare the consistency and make it evenly coated. Auxiliaries include thickeners, dispersants, stabilizers, etc., to ensure that the flame retardant particles are suspended evenly, and the paste is stable and not layered. Among the thickeners, natural or synthetic polymers such as sodium carboxymethyl cellulose and xanthan gum are mostly used to help improve the adhesion of the paste. In order to increase the adhesion and flexibility of the paste, plasticizers or softeners are occasionally added, such as propylene glycol and triethanolamine. In addition, to improve weather resistance, antibacterial properties, or use trace metal ions, emulsified silicone oil, phenol and other agents. But the main purpose is still to focus on flame retardancy, not to overwhelm the guests. In addition, modern flame retardant pastes are still environmentally friendly, so more halogen compounds such as bromine and chlorine are discarded to avoid the formation of smoke and toxic products. Overall, the ingredients of Flame Retardant Paste are based on suppressing fire sources and delaying combustion, supplemented by stabilizing the paste, easy to apply, striving for green environmental protection, and lasting effect, making it widely used in fabrics, wood, plastics, coatings and many other fields. The preparation of this paste requires the proportion of ingredients and precision, and it is necessary to monitor the needs of performance and environment.
What are the application areas of Flame Retardant Paste?
Flame Retardant Paste is the most important thing in today's fire prevention industry. Its function is to contain the spread of fire, slow down the burning speed, and ensure the safety of buildings, facilities and personnel. The field of application is wide and deep, and the main points are briefly described below:
Palace buildings, rely on its help. Bricks and stones may not be flawless, and beams and columns may also be burned. Applying flame retardant paste can enhance the fire resistance, so that the fire will not spread rapidly at that time, and win the opportunity of rescue. It is a powerful tool for building protection. It is used for inner walls, floors, pipes, ceilings, etc., and has been very effective. Urban high-rise buildings, factory warehouses, and subway tunnels especially rely on it.
Electrical equipment also needs fire protection. The cable is heated, insulated or charred, causing a fire. The flame retardant paste can prevent the cable from catching fire. It can also be used to apply a thin layer to the gap between power facilities such as switchboards and switchboards to effectively isolate the flame and protect the safety of the facilities.
Transportation is also respected. Aircraft, subway cars, and passenger trains all need cabins, car bodies, and parts to prevent fires. Apply flame retardant paste to reduce fire losses and protect passenger safety. In addition, car engine cabins and lines can also be prevented from burning.
Petroleum, chemical and other industrial fields, with complex materials, are particularly dangerous. Storage tanks, oil pipelines, and dangerous goods warehouses are mostly applied with flame retardant paste inside and outside to increase their fire resistance and delay disasters.
Communication base stations, data centers, cabinets are numerous, and lines are vertical and horizontal. Once the fire goes off, the loss is incalculable. Use flame retardant paste to protect its joints and eliminate hidden dangers.
Residential decoration, public places, exhibition halls, archive buildings, medical institutions, laboratories, etc., can apply this paste to protect people and utensils.
Cover the area where it is applicable, and almost all places that need fire prevention and disaster reduction can see the shadow of flame retardant paste. Although this object is simple in shape and powerful in effect, it should be carefully selected for its quality and constructed according to specifications, so that it can obtain its comprehensive defense function, which is indispensable for the world.
How to use Flame Retardant Paste?
Flame Retardant Paste is a flame retardant paste, which is designed to prevent fire. Its usage is legal, and the handling must be careful. At first, take the paste and store it in a container, at room temperature and protected from direct sunlight. If you need to apply it, first check the required flame-proof objects. If it is metal, wood, plastic, etc., it can be used. The surface should be clean, dust and oil should be removed, so that the paste and the object are in close contact.
Since the surface has been cleaned, use a scraper, brush or special tool to dip an appropriate amount of flame retardant paste. When applying, it must be evenly spread, not thin or thick. In case of edges, corners, gaps, it is especially appropriate to cover carefully, so that no omission of the paste everywhere. The general practical thickness varies depending on the nature of the object, but it is one to three millimeters. If it is too thick, the dryness will be sluggish, and if it is too thin, the protection will be weak. After it has been applied, let it stand in a ventilated and shady place to dry it. Do not rush to move. It often takes a few hours to a day to dry. In case of damp and rainy, it may be necessary to extend its time appropriately.
After the paste dries, a film layer of toughness will be formed, which is difficult to peel off unless it is strong. It can be applied with paint or decoration at times, which does not hinder the appearance. When the paste encounters fire, it releases non-flammable ingredients, which can effectively slow down the burning rate of objects and deliberately curb the spread of fire. When applying, it is not advisable to be near children and pets, and it is also forbidden to eat After the residual paste is applied, it is sealed and stored to avoid moisture and high temperature.
The property of flame retardant paste is not easy to deteriorate after long-term storage, but it should be checked regularly. The operation is based on safety, and it is safe to abide by the rules. In the end, this method can effectively prevent the disaster of fire, and people can enjoy a safe life.
How to evaluate the flame retardant effect of Flame Retardant Paste?
To evaluate the flame retardant effect of Flame Retardant Paste, it is necessary to follow the principles and principles of the experiment. First select the material suitable for use, apply it proportionally to the surface, and then test it with standard test procedures. Common evaluation methods include vertical combustion method, horizontal expansion method, limiting oxygen index method, etc. For vertical burners, hang the sample vertically to specify the flame to burn from the bottom, and record its continued combustion time, residual flame time and carbonization length. If the flame rests for a moment and the charcoal trace is short, the flame retardant is commendable. For horizontal testers, measure the speed of flame propagation along the surface to judge the shear flame spread of the material. Those with slow fire speed and low burn loss rate are preferred.
There is also the limiting oxygen index method, which is sampled in a closed airflow tube to adjust the oxygen-nitrogen ratio. When the flame is ignited from the top, remember to use the minimum oxygen content that can maintain combustion. High oxygen index indicates that it is difficult to burn. Or use a cone calorimeter to test the released heat and smoke density under fire. If the heat release is low and the smoke is shallow, it is also an excellent flame retardant certificate. In addition, environmental conditions such as temperature and humidity, airflow, etc., must also be fully controlled to ensure the fairness of the data.
Results evaluation, when compared with international standards, such as UL 94, ISO 5660, etc., determine the flame retardant level. During the audit, it must be noted that the formula and dosage of flame retardants affect the effect. After repeated verification by tests, a conclusion can be reached. It is also important to observe the durability and migration of flame retardant paste in practical situations, but it can only be used if it is effective for a long time. If environmental protection standards can be taken into account, it will be more advanced. To sum up, the effectiveness of flame retardant lies in scientific experiments, strict standards, and detailed data review, which are indispensable.
How long is the storage and shelf life of Flame Retardant Paste?
Flame Retardant Paste is a fireproof paste, which is practical to prevent things from burning in case of fire. This paste is thick in texture and has the power of flame retardant. It should be stored properly, and the shelf life is also limited. If you want the paste to last for a long time, consider the storage place first, and always place it in a cool and dry place, away from direct sunlight, away from high temperature, humidity, acid and alkali and flammable things. The container must be sealed to prevent the intrusion of external air and moisture. After using it, it must be tightly sealed to keep its quality unchanged and its properties intact.
If this paste is in contact with the air for a long time, or is heated and damp, the texture may change, and the flame retardant effect will gradually lose. The shelf life of fire retardant used by ordinary people is usually up to two to three years under proper storage conditions. Looking at the packaging of the paste, the date of manufacture and the service life should be clearly stated on it. If it is overdue, it should be inspected first to check its color, odor and consistency. If there is no abnormality, it can still be used as usual; if there is precipitation, stratification, mildew, odor, or drastic change in consistency, it should be discarded to avoid failure and disease.
If a specific type of fire retardant is encountered, and specific additives are added, or its ingredients are different, its shelf life may be reduced. Therefore, the paste storage method should follow the manufacturer's guidelines, respect its storage requirements, and check its qualification date. It is not allowed to be left for a long time at will. As for transportation and handling, both should prevent violent shock or extrusion, ensure the integrity of the packaging, and do not damage the container, resulting in air or moisture intrusion.
All in all, the storage of Flame Retardant Paste should be cautious and law-abiding. The shelf life is about two to three years, but it is better to store it properly. Before use, check its properties carefully and there is no abnormality before you can use it with confidence. In this way, the fire protection effect can be guaranteed, and the utensils can also be safe.
