Kukho iindidi ezininzi zeekhompawundi eziluncedo njengezithinteli zomlilo.Ngelixa ngoku inxalenye encinci yale marike inkulu, iMagnesium Hydroxide itsala ingqalelo ngenxa yokusebenza kwayo, ixabiso, ukubola okuphantsi, kunye netyhefu ephantsi.Imarike yangoku ye-magnesium hydroxide kwi-retardants yedangatye imalunga neshumi lezigidi zeeponti ngonyaka, inamandla okugqithisa amashumi amathathu ezigidi zeeponti ngonyaka kwixa elizayo.
I-Mg (OH) i-2 isetyenziswe njenge-FR kwizicelo zefenitshala yorhwebo e-United States kunye nefenitshala yorhwebo kunye neyokuhlala e-United Kingdom (i-Fire Retardant Chemicals Association 1998).Ukuzinza kwe-Mg(OH)2 kumaqondo obushushu angaphezu kwe-300 ° C kuvumela ukuba kufakwe kwiipolymers ezininzi (IPCS 1997).Idatha ye-Market-volume data epapashwe kwi-1993 iphakamisa ukwandisa ukusetyenziswa kwe-Mg (OH) 2 njenge-FR.Malunga ne-2,000 kunye ne-3,000 yeetoni ze-Mg (OH) 2 zathengiswa njenge-FR e-United States ngo-1986 kunye ne-1993, ngokulandelanayo (IPCS 1997).
I-Magnesium hydroxide (Mg(OH)2), i-acid- kunye ne-halogen-free flame retardant kwiiplastiki ezahlukeneyo.I-Magnesium hydroxide ine-100oC yobushushu obuphezulu bokubola kune-ATH, evumela ubushushu obuphezulu bokucwangcisa ukudibanisa kunye nokukhupha iplastiki.Kwakhona, i-magnesium hydroxide ibhengeza amandla amaninzi ngexesha lenkqubo yokubola.
I-Magnesium hydroxide isebenza njengesithinteli somlilo kunye nesicinezeli umsi kwiiplastiki ikakhulu ngokukhupha ubushushu kwiplastiki ngexesha lokubola kwayo kwi-magnesium oxide kunye namanzi.Umphunga wamanzi owenziweyo unciphisa unikezelo lwamafutha kwidangatye.Iimveliso ezibolileyo zikhusela iplastiki ebushushwini kwaye zivelise i-char ethintela ukuhamba kweegesi ezinokutsha eziya edangatyeni.
Ukuze i-flame retardant ibe luncedo kwiiplastiki ezidityanisiweyo, akufuneki zithobe umgangatho wezinto ezibonakalayo zeplastiki.Kwindlela eqhelekileyo yokwenziwa kwePVC yocingo oluguquguqukayo, iZEHUI CHEM 'yafunyanwa iphucula kancinane iipropathi ezibonakalayo zokwakheka kwePVC xa kuthelekiswa ne-ATH kunye nokhuphiswano, udidi oluphezulu lwe-magnesium hydroxide.
