i-aluminium hydroxideinobumhlophe obuhle, isalathisi sokurhawuzelela esiphakathi, kulula ukuyicubungula, ine-retardant elungileyo yomlilo, i-smoke depressive kunye nezinye iimpawu, ngoko ke i-aluminium hydroxide njengelitye lokwenziwa liyi-filler elungileyo kakhulu.
Iimveliso zelitye ezenziwe nge-aluminium hydroxide zixhobo eziluhlaza zineempawu ezilandelayo:
Ubunzima obulula, ixabiso eliphantsi, ukucutshungulwa okulula, umbala olungileyo, ukuqina okuhle, kunokufezekisa ukuthunga okungenamthungo, kwaye indlela yokwenza kwayo ilula, imfutshane. Ke ngoko, isasazeka ngokukhawuleza kuzo zonke iindawo zehlabathi kwaye ibizwa ngokuba zizinto zokwakha ezisetyenziswa kakhulu.
Okwangoku, ilitye lokwenziwa elithengiswa ehlabathini lonke lifuna malunga neetoni ezingama-700,000 ngonyaka, kwaye malunga ne-10 ekhulwini yesantya sokukhula. Izibalo ezingaphelelanga, imarike yamatye okwenziwa yaseTshayina ifuna ngonyaka kwiimitha ezili-1100 zezikwere ngaphezulu, kwaye amandla emveliso yabavelisi bamatye okwenziwa basekhaya ayi-7 yezigidi zeemitha zesikwere kuphela, nto leyo enika amandla amakhulu emarike.
Ngenxa yenkqubo ekhethekileyo yokusila kunye nenkqubo enzulu yokususa i-silica yesisombululo se-sodium chlorate, iimveliso ze-alumina eziveliswa yinkqubo yokusila i-alkali lime zineempawu zobumhlophe obuphezulu kunye nomxholo ophantsi wesinyithi. Ngokusekelwe kuphuhliso olukhawulezileyo lweshishini lamatye okwenziwa, umgca wemveliso ye-filler aluminium hydroxide uyanda ngokukhawuleza ukuya kwisabelo semarike ekhaya nakwamanye amazwe.
Oku kulandelayo ngabavelisi be-aluminium hydroxide kwilitye lokwenziwa kunye ne-aluminium hydroxide iindlela ezintathu zemveliso ngolu hlobo lulandelayo:
(1) iimveliso eziveliswa ngendlela yokwahlulwa kwekhabhoni zinobumhlophe obuphezulu kancinci, ixabiso le-pH eliphezulu kunye ne-SiO2% yeemveliso, kunye nobunyulu obuphantsi. Ukuveliswa kweemveliso zokwahlulwa kwekhabhoni, ubungakanani bokuqala bengqolowa yemveliso buncinci, umphezulu wengqolowa urhabaxa kakhulu, ikristale yekristale ikhululekile, inqanaba lekristale alikho mhle, iimbobo zinkulu, esi sisizathu sokuba imveliso ifumane ioyile eninzi, kunye nokuveliswa kwayo kwepleyiti yelitye elimhlophe elenziweyo.
(2) ubumhlophe beemveliso eziveliswa yindlela yokwahlulahlula iintlobo buphantsi kancinci, izinga lokufunxwa kweoyile liphantsi, ixabiso le-pH kunye ne-SiO2% yeemveliso ziphantsi, kwaye ubunyulu beemveliso buphezulu. Ukuveliswa kweemveliso, ukukhula kwekristale kugqibelele ngakumbi, umphezulu weenkozo zekristale ucocekile, iikristale zekristale zixineneyo, inqanaba lekristale lilungile, umsantsa phakathi kwamasuntswana mncinci, le yizinga lokufunxwa kweoyile yemveliso eliphantsi elikulungeleyo, kunye nokuveliswa kwayo kweplate yamatye eyenziweyo enamandla aphezulu.
(3) iimveliso eziveliswa yindlela yokuxuba zinezinga eliphantsi lokufunxwa kweoyile kunye nezantsi elimhlophe. Indlela yokuxuba iimveliso, zombini amasuntswana amakhulu ezinto ezikrwada, kunye namasuntswana amancinci e-carbon filler, i-gradation, igcwalisa ngokupheleleyo, yenza imveliso ye-aluminium hydroxide yezinga lokufunxwa kweoyile inciphe kakhulu, kwangaxeshanye, i-viscosity yemveliso iphantsi, ingaphantsi kwe-20000 eps, ngexabiso layo eliphantsi, ukuveliswa kwepleyiti yamatye okwenziwa kunye nabathengi akufuneki banike i-aluminium hydroxide filler, ngaphandle kweLabour.
