Nui nā ʻano hui pū ʻia e like me nā mea pale ahi.ʻOiai i kēia manawa he ʻāpana liʻiliʻi o kēia mākeke nui, ʻo Magnesium Hydroxide ke huki nei i ka nānā ʻana ma muli o kāna hana, kumukūʻai, haʻahaʻa haʻahaʻa, a me ka haʻahaʻa haʻahaʻa.ʻO ka mākeke o kēia manawa no ka magnesium hydroxide i ka lapalapa ahi ma kahi o ʻumi miliona paona i kēlā me kēia makahiki, me ka hiki ke ʻoi aku ma mua o kanakolu miliona paona i kēlā me kēia makahiki i ka wā e hiki mai ana.
Hoʻohana ʻia ʻo Mg(OH)2 ma ke ʻano he FR i nā noi lako mea kūʻai aku ma ʻAmelika Hui Pū ʻIa a me nā lako hale kūʻai a me nā hale noho ma United Kingdom (Fire Retardant Chemicals Association 1998).ʻO ke kūpaʻa o Mg(OH)2 ma nā mahana ma luna o 300°C hiki iā ia ke hoʻohui ʻia i loko o kekahi mau polymers (IPCS 1997).Hōʻike ka ʻikepili ma ka mākeke i paʻi ʻia ma 1993 e hoʻonui i ka hoʻohana ʻana i ka Mg(OH)2 ma ke ʻano he FR.Ma kahi o 2,000 a me 3,000 tons o Mg(OH)2 i kūʻai ʻia ma ke ʻano he FR ma ʻAmelika Hui Pū ʻIa ma 1986 a me 1993 (IPCS 1997).
ʻO ka Magnesium hydroxide (Mg(OH)2), he ʻakika-a me ka halogen-free flame retardant no nā plastik like ʻole.ʻO ka Magnesium hydroxide he 100oC kiʻekiʻe aʻe ka wela decomposition ma mua o ATH, e ʻae ana i kahi mahana hana kiʻekiʻe i ka hoʻohui ʻana a me ka extruding i ka plastic.Eia kekahi, ʻoi aku ka ikaika o ka magnesium hydroxide i ka wā o ka decomposition.
Hana ʻia ka Magnesium hydroxide ma ke ʻano he lapalapa ahi a me ka uahi suppressor i loko o nā plastics ma ka hoʻihoʻi ʻana i ka wela mai ka plastic i ka wā o kona decomposition i ka magnesium oxide a me ka wai.ʻO ka mahu wai i hana ʻia e hoʻoheheʻe i ka lako wahie i ka lapalapa.Hoʻopili nā huahana decomposition i ka plastik mai ka wela a hana i ka pehu e pale ai i ke kahe ʻana o nā kinoea hiki ke puhi ʻia i ka lapalapa.
I mea e pono ai ka pale ahi i loko o nā plastic i hoʻohui ʻia, ʻaʻole pono ia e hoʻohaʻahaʻa i nā waiwai kino o ka plastic.I loko o kahi uea maʻamau PVC formulation, ʻike ʻia ʻo ZEHUI CHEM 'e hoʻomaikaʻi iki i nā waiwai kino o ka hoʻohālikelike PVC i hoʻohālikelike ʻia me ATH a me kahi hoʻokūkū, kiʻekiʻe o ka magnesium hydroxide.
