Anatase titanium dioxide waxaa iska leh midabka midabka titanium dioxide, oo leh awood dabool leh oo xoog leh, awoodda midabaynta sare, iska caabinta cimilada wanaagsan iyo sifooyinka kale, kuwan soo socda ayaa raacaya midabka faraska lacagta si ay u fahmaan habka hagaajinta waxqabadka codsiga anatase titanium dioxide.

1, habka ugu muhiimsan ee lagu wanaajiyo loona dejiyo cadaanka titanium dioxide

Cadaadiska titanium dioxide waxaa saameeya arrimo badan, oo ay ku jiraan ilaha macdanta, qalabka iyo farsamada muhiimka ah.Iyada oo loo marayo tijaabooyin iyo waayo-aragnimada goobta, arrimaha ugu muhiimsan ee saameeya caddaannimadeeda waa: tayada hydrolysis, ka saarida walxaha wasakhda ah iyo xaaladaha calcination.

Waqtigan xaadirka ah, waxaa jira laba nooc oo tignoolajiyada hydrolysis of titanium dioxide ee Shiinaha, hydrolysis cadaadis iyo hydrolysis atmospheric.Laga soo bilaabo falanqaynta tayada hydrolysis iyo tayada alaabta, tayada hydrolysis atmospheric waa ka sii fiican, isku mid ah size qayb hydrolysis.Tayada hydrolysis waa in la hagaajiyo, index tayada of xal titanium xoog waa in si adag loo xakameeyo, ratio birta in titanium iyo content ee adag waa in la xakameeyo gudahood xadka la qoray, iyo xaaladaha hawlgalka ee habka hydrolysis waa in la kordhiyo.

Qodobka kale ee ugu muhiimsan ee saameeya cadaanka titanium dioxide waa qaar ka mid ah walxaha wasakhda leh ee midabka leh, sida: birta, cobalt, nikkel, iwm, waa inay qaadaan tillaabooyin gaar ah si ay meesha uga saaraan, waayo anatase titanium dioxide, macdanta birta sare ee 120ppm, waxay saamaysaa caddaannimadeeda, xitaa ifafaale beddelka midabka iftiinka.Isticmaalka tignoolajiyada bleaching, kordhi xoogga dhaqida birta sare, adigoo ku daraya qaar ka mid ah walxaha waji-xidhka, sida antimony trioxide iyo phosphoric acid, si loo daboolo isku-dhafka birta, waxay yareeyaan saamaynta wasakhda ee cadaanka titanium dioxide.

Xakamaynta xaaladaha calcination waa qayb muhiim ah oo ka mid ah naqshadeynta titanium dioxide xudunta u ah, heerkulka calcination wanaagsan, ka dhigi kara titanium dioxide desulfurization, fuuqbaxa gebi ahaanba, ilaa inta suurtogalka ah si looga fogaado cilladda shalash ee titanium dioxide xudunta u ah, iyo saamayn ay caddaan. .Sidaa darteed, kordhi xakamaynta dhibcaha heerkulka muhiimka ah, isla mar ahaantaana ka dhig qadarka quudinta iyo xawaaraha foornada ee macquulka ah, kordhiya qolka gubashada, iska ilaali xidhiidhka ka dhexeeya alaabta iyo ololka, sintering.

2, qaybinta qaybinta qayb ka qayb titanium dioxide deggan, hagaajinta kala firdhiso titanium dioxide iyo daboosho awoodda

Qaybinta xajmiga walxaha ee titanium dioxide waa tusm dhamaystiran, kaas oo si dhab ah u saameeya sifooyinka midabka iyo codsiga alaabta ee titanium dioxide.Sidaa darteed, dooda ku saabsan awoodda daboolida iyo kala firdhinta ayaa si toos ah loo falanqeyn karaa qaybinta xajmiga qaybta.

Qodobbada saameeya qaybinta cabbirka walxaha ee dioxide titanium waa mid adag.Midka koowaad waa cabbirka cabbirka walxaha asalka ah ee hydrolysis.Cabbirka walxaha asalka ah waxaa lagu hayn karaa xad gaar ah iyadoo la xakameynayo lana hagaajinayo xaaladaha habka biyo-celinta.Marka labaad, heerkulka calcination, habka of calcination of mettitanic acid, qayb ka marto muddo transformation crystal iyo heerka koritaanka, xakameeyo heerkulka ku habboon, si koritaanka qayb ka mid ah kala duwanaansho gaar ah.Ugu dambeeya waa shiidi ee alaabta, sida caadiga ah isbeddelka ee Raymond Mill iyo hagaajinta xawaaraha falanqeeye, xakamaynta tayada shiidi, isla mar ahaantaana, qalabka kale ee shiidi karaa loo isticmaali karaa, sida: dhammaan mishiinka tamarta, qalabka hawo-shiidka iyo dubbaha.

3, iyada oo loo marayo daaweynta dusha sare, hagaajinta waxqabadka codsiga ee titanium dioxide

Titanium dioxide waa budo aad u cidhiidhi ah, dabeecadda waa hydrophilic iyo oleophobic, laakiin haddii adsorption dusha hawada, biyaha iyo wasakhowga kale, kala firidhsanaanta biyaha waa la dhimay, inta badan waxay u baahan yihiin daaweynta dusha, wakiilka daaweynta sida caadiga ah loo isticmaalo alumina fuuqbaxa iyo fuuqbaxa. silicon oxide.Waqtigan xaadirka ah, waxaa sidoo kale jira wax badan oo ka mid ah wakiilada daaweynta dusha ee suuqa, sida: Silicon organic, wakiilka isku-xidhka, iwm, ama qaar ka mid ah midabada kale ee aan organic sida: barium sulfate, aluminium hydroxide, iwm, si loo hagaajiyo sifooyinka dusha sare. ee titanium dioxide, hagaajinaysaa kala firidhsanaanta.
