Kunezigaba eziningi zamakhompiyutha awusizo njengezinqamuleli zomlilo.Nakuba okwamanje ingxenye encane yale makethe enkulu, i-Magnesium Hydroxide idonsa ukunaka ngenxa yokusebenza kwayo, intengo, ukugqwala okuphansi, nobuthi obuphansi.Imakethe yamanje ye-magnesium hydroxide kuma-flame retardants cishe amaphawundi ayizigidi eziyishumi ngonyaka, enamandla okudlula amapondo ayizigidi ezingamashumi amathathu ngonyaka esikhathini esizayo esiseduze.
I-Mg(OH)2 isetshenziswa njenge-FR ezinhlelweni zefenisha yezentengiselwano e-United States kanye nakufenisha yezohwebo neyokuhlala e-United Kingdom (Fire Retardant Chemicals Association 1998).Ukuzinza kwe-Mg(OH)2 emazingeni okushisa angaphezu kuka-300°C kuvumela ukuthi ifakwe kuma-polymers amaningana (IPCS 1997).Idatha yevolumu yemakethe eyanyatheliswa ngo-1993 iphakamisa ukusetshenziswa kwe-Mg(OH)2 njenge-FR.Cishe u-2,000 kanye no-3,000 amathani we-Mg(OH)2 athengiswa njenge-FR e-United States ngo-1986 nango-1993, ngokulandelanayo (IPCS 1997).
I-Magnesium hydroxide (Mg(OH)2), iyi-acid- kanye ne-halogen-free flame retardant kumapulasitiki ahlukahlukene.I-Magnesium hydroxide inezinga lokushisa eliphezulu lokubola elingu-100oC kune-ATH, okuvumela izinga lokushisa eliphakeme lokucubungula ekuhlanganiseni nasekukhipheni ipulasitiki.Futhi, i-magnesium hydroxide ikhangisa amandla amaningi phakathi nenqubo yokubola.
I-Magnesium hydroxide isebenza njengesicindezeli ilangabi kanye nesicindezeli sentuthu kumapulasitiki ikakhulukazi ngokukhipha ukushisa epulasitiki ngesikhathi sokubola kwayo ibe yi-magnesium oxide namanzi.Umhwamuko wamanzi okhiqizwayo unciphisa ukunikezwa kukaphethiloli elangabini.Imikhiqizo ebolayo ivikela ipulasitiki ekushiseni futhi ikhiqize ukusha okuvimbela ukugeleza kwamagesi okungenzeka avuthe elangabini.
Ukuze i-flame retardant ibe wusizo kumapulasitiki ahlanganisiwe, akumele ilulaze izici ezibonakalayo zepulasitiki.Ekwakhekeni kwe-PVC yentambo evamile eguquguqukayo, i-ZEHUI CHEM' itholakale ithuthukisa kancane izakhiwo ezingokomzimba zokwakheka kwe-PVC uma kuqhathaniswa ne-ATH kanye ne-magnesium hydroxide yebanga eliphezulu eqhudelanayo.
