Ukusetyenziswa kweTitanium Dioxide kwiShishini lePlastiki

Ukusetyenziswa kwe-titanium dioxide (TiO2₂) kwishishini leplastiki kubonakala kakhulu kwezi zinto zilandelayo: njenge-pigment eyintloko, inokuphucula kakhulu ubumhlophe kunye namandla okugquma kweemveliso zeplastiki, ifezekise ukukhanya okuphezulu ngokusasaza kunye nokufunxa ukukhanya, ingakumbi kwi-yellowing prone resins, i-titanium dioxide encinci enobubanzi obuyi-0.15-0.3 μ m inokuvelisa isigaba semvelaphi eluhlaza okwesibhakabhaka ukuphucula isiphumo sokugquma; Kwangaxeshanye, i-titanium dioxide iyalibazisa ukuguga kweplastiki kwaye iphucula ukumelana nemozulu ngokufunxa ukukhanya kwe-ultraviolet. Iimveliso zangaphandle kufuneka zisebenzise uhlobo lwe-rutile kwaye zongezwe ngetekhnoloji yonyango lomphezulu efana ne-silicon, i-aluminium, kunye ne-zirconium ukuthintela iingxaki ze-pore ezibangelwa kukufuma kwamanzi ngexesha lokucubungula ubushushu obuphezulu; Ngokuphathelele ukuzinza kobushushu, i-titanium dioxide inokuphucula ukusebenza kweplastiki kwiindawo ezinobushushu obuphezulu ngokunciphisa umsebenzi we-photochemical ngokusebenzisa iindlela zokuguqula umphezulu (ezifana nokwaleka okungekho ngokwemvelo), ukuqinisekisa amandla oomatshini kunye nokuqina kombala weemveliso phantsi kweemeko ezinzima. Iindlela zokusebenzisa i-titanium dioxide ziyahluka kwiintlobo ezahlukeneyo zeplastiki – ii-polyolefins zifuna ingqalelo kwiipropati zokusasazeka kunye nokungaguquguquki kombala, izinto eziqinileyo ze-PVC zixhomekeke kubuchule bokulwa nomgubo we-titanium dioxide, ngelixa i-ABS igxile ekulinganiseni iipropati zokukhanya kunye nezoomatshini. Kwiinkqubo eziqhelekileyo, ubungakanani be-titanium dioxide eyongeziweyo buhlala bulawulwa kwi-3% ~ 5% ukulinganisela uqoqosho kunye nokusebenza, kwaye uxinzelelo kwiidayi ezikhethekileyo lunokufikelela kwi-40% ~ 70%; Ngokuphucula ukusasazwa kobukhulu beesuntswana (ezifana ne-2-35 μ m) kunye neenkqubo zonyango lomphezulu, i-Bontecn Group China titanium dioxide ifikelele kumhlophe ophezulu, ukumelana nemozulu, kunye nokuzinza kokucubungula kwiindawo ezifana neefilimu zeplastiki, iiprofayili zomnyango kunye neefestile, kunye nezixhobo zemoto.
