What are the main flame retardant properties of Rigid Foam Flame Retardant?
Rigid Foam Flame Retardant is also the flame retardant of the foam. Its property is strong, and it has good insulation, so it is used in construction, home, and transportation areas. However, the foam is flammable, quick-burning and toxic in case of fire, which is important for personal safety, so it needs to be flame retardant to increase its safety. The main flame retardant properties are as follows:
One is the flame retardant rate. The flame retardant is inserted into the foam material, which is like a barrier, so that the material is exposed to the fire source and does not cause rapid ignition. Its production or non-flammability, or absorption decomposition and inert release, dilute and flammable flame, so that the burning rate is reduced.
Both, inhibit. Some flame retardants can be released in the combustion process, such as bromine, phosphorus or flame retardants, more than in the combustion process, so that black and harmful substances are less, to ensure the safety of evacuation, and to reduce the generation of carbon monoxide, cyanide and other dangerous substances.
Three, carbonization is generated. Some flame retardants can promote the formation of dense carbon at high temperatures, which is coated on the surface of the material to prevent the further invasion of oxygen, so that the unburned material is not delayed, and the integrity of the material is maintained, and the spread of the fire is delayed.
Four, the chemical effect is stopped. The elements in the flame retardant can decompose and generate active free radicals, which can stop or inhibit the active molecules in the combustion reaction, so that the flame can be maintained, that is, the flame retardant process on the molecular surface.
Five of them are compatible with various polymers and have both flame retardant and mechanical properties, so they are highly recommended. The guarantee requirements are high, and the new type of flame retardant has also been widely used, which is also safe for the human environment.
Of course, Rigid Foam Flame Retardant has multiple effects such as flame retardant, poison suppression, carbon promotion, and combustion in the chemical industry. It makes the foam safer in various applications and can be an indispensable part of modern engineering materials.
Where can Rigid Foam Flame Retardant be applied?
Rigid Foam Flame Retardant is a flame retardant material of solid foam. Its material is light, has good thermal insulation, and has the characteristics of flame resistance. Since its invention, it has been widely used in many fields to prevent fire and ensure peace.
Palace houses, building buildings and castles, afraid of fire invasion, often use this material to interlayer between walls and ceilings. It can not only insulate heat, but also prevent fire from spreading. Factory warehouses, confidential heavy land, especially fire protection, often apply flame retardant foam at the partition door panels to ensure safety. Modern metropolis, with many buildings, strict fire regulations, flame retardant foam is widely distributed in elevator shafts and ventilation ducts, flame retardant and smoke-proof, protecting people's safety. Rail cars, automobiles, ships, aviation and other transportation fields, are airtight and narrow, especially for prevention of disasters. It is widely used between the inner cabin panels, ceilings, and seats, which is not only light and weight-reducing, but also to reduce the risk of fire. Household appliances, cold box air conditioners, water heaters, and various household appliances also rely on this material to ensure the safety of the residence.
Petrochemical, flammable and explosive, pipelines and storage tanks of plant installations must be equipped with flame retardant foam for fire prevention. Information room, old and new cables are staggered. In case of fire, this material is often installed to protect the line from burning. Theaters, exhibition halls, public halls, and public gathering places are equipped with flame retardant equipment for their decoration ceilings and baffles to keep them safe. New energy vehicles, energy storage power stations, lithium batteries accumulate, and fire risks are frequent. Therefore, solid flame retardant foam is installed in various departments to prevent problems before they occur.
Overall, Rigid Foam Flame Retardant is widely used in buildings, transportation, household, industry, energy, public venues and many other fields due to its lightweight, high-strength, heat-resistant, and flame-resistant characteristics. Not only does it ensure the safety of utensils, but it also protects the people from fire disasters. It has made great contributions to the contemporary world.
What is the environmental performance of Rigid Foam Flame Retardant?
Rigid Foam Flame Retardant is a flame retardant foam product used in today's building materials and industrial fields. As the world knows, thermal insulation and fire protection are important for buildings, but environmental protection performance cannot be ignored. Looking at its production method, most of them are polymer-based, supplemented by flame retardants. Commonly used flame retardants are halogen, organophosphorus, aluminum magnesium hydroxide and halogen-free environmentally friendly new materials. From the perspective of environmental protection, its performance can be divided into advantages and disadvantages, and cannot be generalized.
Halogen flame retardant has good flame retardant effect, but it is easy to release toxic smoke and long-term pollution when burned, which is harmful to humans, animals and ecology. Waste is difficult to degrade, and it will accumulate harm for a long time. European countries banned it and advocated halogen-free substitution. As for organic phosphorus, although it has been partially improved, it also has potential environmental risks. If aluminum magnesium hydroxide or halogen-free environmentally friendly flame retardants are used, the precipitation of harmful substances can be greatly reduced, and the residue after combustion is easy to deal with, which is more environmentally friendly.
However, there are many links in the production of foaming materials from self-made to waste. If the emission of harmful substances such as VOCs can be controlled during production, and renewable resources can be used, it can increase environmental benefits. If it is not easy to decompose and release toxic particles during use, it is particularly safe. If the waste treatment can be recycled or safely incinerated without harming soil and water bodies, it will be worry-free. If the additives are used indiscriminately or the technology is not refined, it is dangerous to poison all things.
Looking at today's green building standards, it has clearly standardized material environmental protection indicators and advocated a full life cycle perspective. Rigid Foam Flame Retardant materials, if they use new high-efficiency halogen-free flame retardants, cooperate with green preparation processes, and strengthen back-end recycling and degradation, can conform to the purpose of ecological civilization.
Overall, the environmental performance of Rigid Foam Flame Retardant is closely related to the flame retardant technology used, raw material sources, production processes and waste management. If it can be removed from its harm and preserved for good use, it can take into account safety and environmental protection, and become an excellent material advocated by the times. On the contrary, if you ignore the responsibility of environmental protection, you will be evaded and eliminated. The way of environmental protection is to start with caution and end with caution.
How to use Rigid Foam Flame Retardant?
Rigid Foam Flame Retardant is also a rigid foam flame retardant. It is mainly used to improve the flame retardant properties of foam materials and is widely used in construction, furniture, transportation and other fields. The method of use must be carefully followed in accordance with regulations to obtain its maximum effect and ensure safety. The method is as follows:
1. Prepare utensils. Clean the utensils and tools required for mixing and spraying in advance, and do not let dust impurities mix in, so as not to affect the ratio and reaction. When using, it is appropriate to wear protective equipment such as gloves and masks to protect the body.
2. Proportion. According to the instructions provided by the factory, take an appropriate amount of Rigid Foam Flame Retardant and mix it in proportion with the main foam raw materials (such as polyurethane prepolymer, foaming agent, etc.). The weighing must be fine, and the mixing must be uniform. If the proportion is not correct, the flame retardant performance will be poor, and the foam structure may be loose or fragile.
3. Stir with heat. Some formulas need to be heated to make the flame retardant blend more evenly with the raw materials, and some should not be mixed too fast to prevent excessive bubbles. Stirring is expensive to be uniform and moderate, and do not allow the precipitation to remain at the bottom.
4. Shape and form. After the mixture is completed, quickly pour it into the mold or spray it directly on the desired substrate. After pouring, it is advisable to absorb vibration and not suddenly cool, so as not to affect the density and integrity of the foam forming.
Five, curing and maintenance. After the foam is formed, it is placed in a ventilated and cool place and cured naturally. The length of time depends on the formula and environment. Do not move it arbitrarily during the initial solidification period. After it is completely consolidated, it can be transported and used.
Six, safe disposal. After use, residual liquids and waste utensils must be properly cleaned up in accordance with the management of hazardous chemicals. Do not pour it at will to prevent pollution. If it accidentally stains the skin, it should be rinsed with water in time.
In short, the use of Rigid Foam Flame Retardant is expensive for accurate measurement, rigorous mixing, and implementation in accordance with the process sequence. Then the flame retardant performance of the foam can be greatly improved, with both safety and durability, which can benefit all kinds of applications such as human settlements, industry and commerce. However, it is also necessary to carefully guard against the risks of operation to ensure safety.
