应用：
它有整个阻燃剂市场的大约38％的市场份额，其每年的市场容量总计约60万吨。 此白色结晶固体从铝土矿生产的。 ATH阻碍火，因为它是吸热分解成三氧化二铝和水。 该过程需要消耗能量，削弱可燃气体和形成一个氧化层，以防止能量和氧的进入。 因此，ATH是一种非常有效的阻燃剂为在许多应用中使用; 尤其玻璃纤维增强塑料，合成大理石，电缆和电线，以及电绝缘体。 ATH是易于分散于水中，作为其极性性质的结果，促进水基涂料中使用。 在塑料，橡胶，玻璃钢，SMC中使用的普通的填料，DMC模塑和其它聚合物仅氧化铝三水合物具有阻燃和抑烟性能，以及作为一种经济的树脂剂。 氧化铝化学及浇注料的领先开发商与ATH的处理器。 ATH是用在聚酯树脂。 然而，随着被日益重视烟雾及有毒气体排放，ATH发现在乙烯大量应用程序作为低烟，无毒代替锑，聚氨酯，橡胶，氯丁橡胶泡沫系统，橡胶，电线电缆绝缘层，乙烯墙 与地板覆盖物和环氧树脂。 三水合氧化铝作为由于其热力学性质的阻燃剂和烟雾抑制剂。 它的吸热脱水冷却的塑料和橡胶部件和用水稀释蒸汽的可燃气体那些逃脱。 后者可能与抑烟等优异性能相关的主要现象包括电和跟踪性。 ATH在涂料行业也使用。 ATH可以代替高达的二氧化钛颜料的25％，因此是一种经济的增量减少生产成本。

Precipitation Aluminium Hydroxide for Flame Retardant
Molecular formula: Al (OH) 3
Molecular Weight: 78.0
CAS No.: 21645-51-2
Hs Code: 28183000
Application:
It has a roughly 38 percent share of the entire flame retardant market, and its annual market volume totals approximately 600000 tons. This white, crystalline solid is manufactured from bauxite. ATH hinders fire because it is endothermically decomposed into aluminum oxide and water. The process consumes energy, weakens flammable gases and builds an oxide layer to protect against the entry of energy and oxygen. Accordingly, ATH is a very effective flame retardant for use in many applications; especially fiberglass reinforced plastics, synthetic marble, electrical cables and wires, as well as electrical insulators. ATH is easily dispersible in water, as a result of its polar nature, facilitating use in water-based paints. Of the Common fillers used in Plastics, Rubber, FRP, SMC, DMC moulding and other polymers only Alumina Trihydrate has flame retarding and smoke suppressing properties as well as being an economical resin extender. Alumina Chemical & Castables is the leading developer & Processor of ATH. ATH is used in polyester resins. However with increased attention being given to smoke & toxic fume emissions, ATH has found large volume application in vinyl as a low smoke, non toxic replacement for antimony and in polyurethane, latex, neoprene foam system, Rubber, wire & Cable insulation, vinyl walls & flooring coverings and epoxies. Alumina Trihydrate acts as a flame retardant and smoke suppressor because of its thermodynamic properties. Its endothermic dehydration cools the plastic & Rubber parts and dilute with water vapour those combustible gases that do escape. The latter is probably the main phenomenon associated with smoke suppression other excellent performance include electrical and track resistance. ATH is also use in Paints Industries. ATH can replace upto 25% of the Titanium dioxide pigment & therefore is an economical extender reducing production cost.
