What are the characteristics of flame retardants? Antimony trioxide manufacturers to explain for you

Antimony trioxide manufacturers believe that any combustion in a short period of time the heat is limited. If a part of the heat emitted by the fire source can be absorbed in a short time, the flame temperature will be reduced, and the heat of radiation on the surface of the combustible material and acting on the vaporization of the combustible molecules will be reduced, and the combustion reaction will be suppressed to a certain extent. At high temperatures, the flame retardant has a strong endothermic reaction, absorbs part of the heat released by combustion, reduces the surface temperature of combustibles, effectively inhibits the generation of combustible gases, and prevents the spread of combustion.

Some common sense of flame retardant, antimony trioxide manufacturers for you

Antimony trioxide manufacturers believe that the flame retardant effect of inorganic flame retardants is mainly to use the heat storage and thermal conductivity of large specific volume fillers to make the material difficult to reach the decomposition temperature, or to absorb heat through the thermal decomposition of flame retardants, thereby alleviating or terminating the heating process of the main material. The flame retardant mechanism is the release of crystal water when heated, evaporation decomposition release water vapor. This reaction process needs to absorb a large amount of combustion heat energy, which greatly reduces the surface temperature of the material and greatly reduces the probability of thermal decomposition and combustion of polymer materials.

What is the future development of antimony trioxide?

Antimony trioxide is an inorganic compound with the chemical formula Sb2O3. Natural products called antimony, commonly known as antimony white, white crystalline powder. Melting point 655 ℃. Boiling point 1550 ℃. Soluble in sodium hydroxide solution, hot tartaric acid solution, bitartrate solution and sodium sulfide solution, slightly soluble in water 370±37 μg/L, dilute nitric acid and dilute sulfuric acid. There is a carcinogenic possibility. There are two kinds of preparation methods, dry and wet, which are mainly used for white pigments, paints and plastics, and can play the role of pigments and flame retardants.

Analysis of the main role of antimony trioxide!

Function one: Antimony trioxide is used as white pigment, white glass, enamel, medicine, cementing cement, filler, mordant and fireproof coating, etc;

What are the characteristics of antimony trioxide?

Antimony trioxide is the earliest flame retardant, suitable for epoxy resin, polyurethane, chloroprene rubber, polystyrene, polyvinyl chloride, polyester, etc., when used alone, the dosage is large, the flame retardant effect is poor (unless the flame retardant contains halogen), when combined with halogen compound (R.HX), it has good synergistic effect, and the flame retardant effect is obviously improved.

The role and use of antimony trioxide

Use one: Antimony trioxide used as white pigment, white glass, enamel, medicine, cement, filler, mordant and fire retardant coating, etc;

Antimony trioxide flame retardant formula!

Most polymer materials are flammable, which will produce a lot of smoke and harmful gases in the combustion process, which seriously endanger the safety of human life, so it is very meaningful to carry out flame retardant treatment. Antimony trioxide is a highly efficient additive flame retardant, which can be used independently or with other flame retardants and smoke suppressants.

The main purpose of antimony trioxide!

Use a: used as white pigment, white glass, enamel, medicine, cement, filler, mordant and fire retardant coating, etc.
