Dioxyde ya Titanium yo Kumenyekanisha Umuhanda
Ibisobanuro ku bicuruzwa
Dioxyde ya Titanium (TiO2) ni amabuye y'agaciro asanzwe akoreshwa mu nganda zitandukanye.Ku bijyanye n'ibimenyetso byo kumuhanda, dioxyde ya titanium ni ingenzi cyane kubera imiterere yihariye ya optique.Igipimo cyacyo cyo hejuru cyane cyerekana urumuri rwiza kandi rugaragara, bigatuma ibimenyetso byumuhanda bigaragara cyane no mumucyo muke.Ibi ni ngombwa cyane cyane iyo utwaye nijoro cyangwa mubihe bibi byikirere aho bigaragara neza.
Usibye kugaragara neza, dioxyde ya titanium itanga igihe kirekire.Kumenyekanisha ibimenyetso byumuhanda mubihe bidukikije nkibinyabiziga byinshi, ubushyuhe bukabije hamwe nimirasire ya UV birashobora kwangirika vuba.Nyamara, ibimenyetso byumuhanda birimo TiO2 birwanya cyane kuzimangana, gukata no kwambara biterwa nibi bintu, bigatuma ubuzima bumara igihe kirekire kandi amafaranga yo kubungabunga make.
Kimwe mu byiza byingenzi byo gukoresha dioxyde ya titanium mukumenyekanisha umuhanda ni ibidukikije byangiza ibidukikije.Bitandukanye n’ibindi pigment, dioxyde ya titanium ntabwo ari uburozi, ntabwo ishobora guteza akaga kandi ntabwo ishobora guteza ingaruka mbi ku bidukikije cyangwa ku bakozi.Byongeye kandi, ibimenyetso byerekana umuhanda wa titanium dioxyde ntibisohora imiti yangiza mu kirere, bigatuma ihitamo neza ibikorwa remezo byo gutwara abantu.
Byongeye kandi, dioxyde ya titanium ifite ubushobozi bwo kwerekana no gusasa urumuri, bikagabanya gukenera amatara yinyongera kumuhanda.Ntabwo ibyo bizigama ingufu gusa kandi biteza imbere kuramba, binatezimbere kugaragara kubashoferi nabanyamaguru.
Kubijyanye no kubishyira mu bikorwa, dioxyde ya titanium irashobora kwinjizwa byoroshye mubikoresho bitandukanye biranga umuhanda nkibara, amarangi, thermoplastique na epoxies.Irashobora gukoreshwa mubimenyetso bitandukanye byumuhanda, harimo umurongo wo hagati, impande zose, inzira nyabagendwa hamwe nibimenyetso, byerekana neza kandi bihujwe kumurongo wumuhanda.
Mu gishushanyo mbonera cyo gusiga amarangi, usibye guhitamo icyiciro cya dioxyde de titanium ikwiye, ikindi kibazo cyingenzi nuburyo bwo kumenya uburyo bwiza bwo gukoresha dioxyde ya titanium.Ibi biterwa no gukenera gutwikirwa ariko kandi bigurishwa nizindi mpamvu nka PVC, guhanagura no gutatanya, ubunini bwa firime, ibirimo ibintu bikomeye ndetse no kuba hari ibindi bibara byamabara.Kubushyuhe bwicyumba gikiza ibishishwa byera bishingiye kuri solide, ibirimo dioxyde ya titanium irashobora gutoranywa kuva 350kg / 1000L kugirango ube mwiza cyane kugeza kuri 240kg / 1000L kugirango ube ubukungu mugihe PVC ari 17.5% cyangwa igipimo cya 0,75: 1.Igipimo gikomeye ni 70% ~ 50%;kubishushanyo mbonera bya latex, mugihe PVC CPVC, ingano ya dioxyde ya titanium irashobora kugabanuka hamwe no kwiyongera kwingufu zihishe.Mubintu bimwe byubukungu byubukungu, ingano ya dioxyde ya titanium irashobora kugabanuka kugera kuri 20kg / 1000L.Mu nyubako ndende yubatswe hejuru yurukuta rwimbere, ibirimo dioxyde ya titanium irashobora kugabanuka kurwego runaka, kandi gufatira hamwe na firime ya coating nabyo birashobora kwiyongera.
