Nkumukoresha wa kabiri munini ukoresha dioxyde de titanium, inganda za plastike nu murima wihuta cyane mu myaka yashize, hamwe n’ikigereranyo cy’ubwiyongere bwa buri mwaka cya 6%.Mu byiciro birenga 500 bya dioxyde de titanium ku isi, amanota arenga 50 yeguriwe plastiki.Gukoresha dioxyde ya titanium mubicuruzwa bya pulasitike, usibye gukoresha imbaraga zayo zihishe, imbaraga nyinshi za acromatique nibindi bintu bya pigment, irashobora kandi kunoza ubushyuhe, kurwanya urumuri hamwe n’ikirere cy’ibicuruzwa bya pulasitiki, ku buryo ibicuruzwa bya pulasitiki birindwa Itara rya UV.Igitero, kunoza imiterere yubukanishi n amashanyarazi yibicuruzwa bya plastiki.
Kubera ko ibicuruzwa bya pulasitike bifite umubyimba mwinshi kuruta amarangi na wino, ntibisaba ubunini bwinshi bwa pigment, wongeyeho bifite imbaraga zo guhisha hamwe nimbaraga zikomeye zo gusiga, kandi dosiye rusange ni 3% kugeza 5% gusa.Ikoreshwa hafi ya yose ya thermosetting hamwe na plastiki ya termoplastique, nka polyolefine (cyane cyane polyethylene nkeya), polystirene, ABS, chloride polyvinyl, nibindi. Irashobora kuvangwa nifu yumye cyangwa yongeweho.Icyiciro cyamazi ya plastike ivanze, kandi bimwe bikoreshwa nyuma yo gutunganya dioxyde ya titanium muburyo bukomeye.

Isesengura ryihariye rya dioxyde ya titanium mu nganda za pulasitike n’inganda zikora amabara

Hafi ya dioxyde ya titanium ya plastike ifite ubunini buke ugereranije.Mubisanzwe, ingano ya dioxyde ya titanium yo gutwikira ni 0.2 ~ 0.4 mm, mugihe ingano ya dioxyde ya titanium ya plastike ari 0.15 ~ 0.3μm, kugirango haboneke ubururu bwubururu.Ibisigarira byinshi hamwe nicyiciro cyumuhondo cyangwa resin byoroshye kumuhondo bigira ingaruka zo guhisha.

Dioxyde ya Titanium ya plastiki isanzwe muri rusange ntabwo ikorerwa hejuru yubutaka, kubera ko dioxyde ya titanium yometseho ibikoresho bidafite ingufu nka alumina isanzwe ya hydrated hydrème, iyo ubuhehere bugereranije ni 60%, amazi ya adsorption equilibrium agera kuri 1%, mugihe plastiki yakubiswe mubushyuhe bwinshi .Mugihe cyo gutunganya, guhumeka kwamazi bizatera imyenge kugaragara hejuru ya plastike yoroshye.Ubu bwoko bwa dioxyde ya titanium idafite ibinyabuzima bidasanzwe bigomba kuvurwa hejuru yubutaka (polyol, silane cyangwa siloxane), kubera ko dioxyde ya titanium ikoreshwa muri plastiki.Bitandukanye na dioxyde ya titanium yo gutwikira, iyambere iratunganywa kandi ikavangwa muri resin-polarite nkeya ikoresheje imbaraga zo kogosha, kandi dioxyde ya titanium nyuma yo kuvurwa hejuru yubutaka irashobora gukwirakwira neza muburyo bwo gukata imashini.

Hamwe nogukomeza kwagura ibikorwa bya plastiki, ibicuruzwa byinshi bya plastiki byo hanze, nkinzugi za plastike nidirishya, ibikoresho byubwubatsi nibindi bicuruzwa bya pulasitiki byo hanze, nabyo bifite ibisabwa cyane kugirango birwanya ikirere.Usibye gukoresha dioxyde ya rutile ya titile, hakenewe no kuvurwa hejuru.Ubu buryo bwo kuvura busanzwe ntabwo bwongera zinc, gusa silicon, aluminium, zirconium, nibindi byongeweho.Silicon ifite hydrophilique na dehumidifike, ishobora kubuza ko habaho imyenge bitewe no guhumeka kwamazi mugihe plastiki isohotse mubushyuhe bwinshi, ariko ingano yibi bikoresho byo kuvura hejuru ntabwo ari byinshi cyane.
