Ukusetshenziswa kwe-Titanium Dioxide Embonini Yepulasitiki

Ukusetshenziswa kwe-titanium dioxide (TiO2₂) embonini yepulasitiki kubonakala kakhulu kulezi zici ezilandelayo: njenge-pigment eyinhloko, ingathuthukisa kakhulu ubumhlophe namandla okumboza imikhiqizo yepulasitiki, ifinyelele ukukhanya okuphezulu ngokuhlakazeka nokumuncwa kokukhanya, ikakhulukazi kuma-resin aphuzi, i-titanium dioxide encane enobubanzi obungu-0.15-0.3 μ m ingakhiqiza isigaba sangemuva esiluhlaza okwesibhakabhaka ukuthuthukisa umphumela wokumboza; Ngesikhathi esifanayo, i-titanium dioxide ibambezela ngempumelelo ukuguga kwepulasitiki futhi ithuthukise ukumelana nesimo sezulu ngokumunca ukukhanya kwe-ultraviolet. Imikhiqizo yangaphandle idinga ukusebenzisa uhlobo lwe-rutile futhi ingezwe ngobuchwepheshe bokwelashwa kwendawo njenge-silicon, i-aluminium, ne-zirconium ukuvimbela izinkinga ze-pore ezibangelwa ukuhwamuka kwamanzi ngesikhathi sokucubungula izinga lokushisa eliphezulu; Ngokuphathelene nokuzinza kokushisa, i-titanium dioxide ingathuthukisa ukusebenza kwepulasitiki ezindaweni ezishisa kakhulu ngokunciphisa umsebenzi we-photochemical ngamasu okuguqula indawo (njengokumboza okunga-organic), ukuqinisekisa amandla omshini nokuqina kombala wemikhiqizo ngaphansi kwezimo eziyinkimbinkimbi. Amasu okusetshenziswa kwe-titanium dioxide ayahlukahluka ezinhlotsheni ezahlukene zepulasitiki – ama-polyolefin adinga ukunakwa ekuhlakazekeni nasekuvikeleni ukubola kombala, izinto eziqinile ze-PVC zithembele ekhonweni lokulwa nophuphu lwe-titanium dioxide, kuyilapho i-ABS igxile ekulinganiseni izakhiwo zokukhanya nezomshini. Ezisetshenzisweni ezijwayelekile, inani le-titanium dioxide engeziwe livame ukulawulwa ku-3% ~ 5% ukuze kulinganiswe umnotho nokusebenza, futhi ukuhlushwa kwezinto ezikhethekile zombala kungafinyelela ku-40% ~ 70%; Ngokwenza ngcono ukusatshalaliswa kosayizi wezinhlayiya (njenge-2-35 μ m) kanye nezinqubo zokwelashwa kwendawo, i-Bontecn Group China titanium dioxide ifinyelele ubumhlophe obuphezulu, ukumelana nesimo sezulu, kanye nokuzinza kokucubungula emasimini afana namafilimu epulasitiki, amaphrofayili omnyango namafasitela, kanye nezingxenye zezimoto.
