Cov hlau oxide liab raw khoom peb niaj hnub siv feem ntau siv hauv kev lag luam ntau vim nws qhov xim ci thiab xim muaj zog zoo dua. Ntawm lawv, kev siv thiab tsim hauv kev lag luam ceramic yog qhov zoo. Cia peb saib cov hlau oxide liab hauv kev lag luam ceramic. Hauv kev siv.
1. thov:
Cov khoom lag luam Ceramic tau muab faib ua xya pawg: architectural ceramics, ceramics huv, vaj iav ceramics, kos duab ceramics, niaj hnub siv ceramics, ceramics industrial, thiab tshwj xeeb ceramics. Iron oxide pigments yog siv dav hauv xya hom ntawm cov khoom siv ceramic.
2. Cov yam ntxwv thiab cov hauv paus ntsiab lus:
Iron oxide pigments muaj xim muaj xim. Cov khoom tha xim ntawm cov hlau oxide tsuas yog siv rau hauv ceramics los npaj cov xim ntau ntawm cov dej ntsej muag. Vim muaj qhov sib txawv ntawm cov hlau ions, cov hlau oxide nws tus kheej yog ntau xim. Thaum cov hlau oxide ntxiv rau lwm qhov chaw ci ntsa iab, Ua rau cov xim ci ci nplua nuj thiab ci ntsa iab. Tsis tas li ntawd, hauv cov txheej txheem ceramic (ci) cov txheej txheem tsim, cov hluav taws kub sib txawv tau siv, thiab cov xim ntawm hlau oxide kuj sib txawv. Hauv qhov chaw muaj oxidizing nplaim hluav taws, cov xim ntawm hlau oxide hloov los ntawm daj mus rau xim av xim av, thiab tom qab ntawd hloov mus rau txiv kab ntxwv liab. Xim av. Hauv cov huab cua txo qis, xim hloov pauv ntawm xiav rau grey thiab tsaus. Cov kev hloov pauv no yog tshwm sim los ntawm kev sib nrig sib hloov pauv ntawm qhov sib npaug ntawm qhov zoo sib xws ntawm Fe2+ thiab Fe3+ hauv txheej txheej nplaum.
1. Daim ntawv thov ntawm hlau oxide ua raw khoom rau lub cev ntsuab: lub cev ntsuab yog lub hauv paus cov khoom siv rau cov khoom siv ceramics.
Cov hlau oxide yog siv los ua cov khoom siv xim ntawm lub cev ntsuab, uas yog siv rau hauv phab ntsa thiab pem teb nplais khoom lag luam ntawm cov khoom siv txua zeb. Piv txwv, rau imitation granite unglazed vuas vov cov vuas, cov txheej txheem npaj xim:
Cov hlau oxide xim thiab cov khoom siv me me ntawm cov khoom siv sib xyaw ua ke rau hauv cov xim sib xyaw rau hauv cov pob zeb, thiab tom qab ntawd tswj los ntawm lub tshuab nqus hlau kom nkag mus rau hauv qhov tov. Hauv qhov tov, ib qho kev faib ua feem ntawm cov xim muab tshuaj thiab lub hauv paus muab tshuaj yog sib xyaw ntawm kev kub ceev los ua cov xim muab tshuaj. Txau rau hauv lub tshuab ziab kom qhuav los tsim cov xim dawb.
2. Kev thov cov hlau oxide hauv cov xim ci ceramic: Cov nplaim ntsej muag yog cov txheej txheem txuas ntxiv mus rau cov nplais ceramic.
Hauv cov khoom siv dog dig zoo tib yam, cov cuab yeej tha xim ntawm cov hlau oxide tsuas yog siv los npaj ntau xim ntawm glaze dej. Tus nqi ntawm cov hlau ions nws txawv, thiab cov hlau oxide nws tus kheej nthuav tawm xim sib txawv. Piv txwv li, hlau trioxide (Fe2O3) yog hmoov liab, thiab ferrous oxide (FeO) thiab ferroferric oxide (Fe3O4) yog hmoov dub. Sib txawv cov hlau oxide sib txuas tuaj yeem xaiv tau raws li kev xav tau. Ntxiv nrog rau cov xim muaj hlau ntau xim nws tus kheej, thaum hlau oxide ntxiv rau lwm yam ntsej muag, nws tuaj yeem ua rau cov ntsej muag ci nplua nuj thiab ci ntsa iab. Piv txwv li, hlau oxide ntxiv rau ntxiv rau lub ntsej muag boric acid uas muaj alkali co xim kom qhia tau cov xim liab ntawm cov cawv; thaum hlau oxide ntxiv rau semi-matte thiab matte dawb ci, nws nthuav tawm cov duab ci ntawm lub teeb xim av, lub teeb daj thiab grey mus rau xim av tsaus; thaum thaum hlau oxide siv los ua kom daj daj, tsuas yog ob peb feem pua ntawm cov hlau oxide xav tau ntxiv txhawm rau qhia cov xim daj muaj zog.
Thaum siv cov hlau oxide pigments, peb tuaj yeem xaiv cov xim raws li qhov sib txawv ntawm kev siv. Cov hlau oxide liab, daj, ntsuab, dub, xiav, thiab lwm yam xim muaj, thiab tuaj yeem yuav lawv los ntawm lawv tus kheej.
