Vim li cas praseodymium oxide dav siv hauv iav teb?

Praseodymium oxide hmoovyog dav siv nyob rau hauv lub iav teb vim nws muaj zoo heev colouring functions. Nws tuaj yeem tso cov iav nrog cov xim tshwj xeeb, ci ntsa iab thiab ruaj khov zoo li ntsuab, uas tuaj yeem siv rau hauv ntau yam khoom xws li iav kos duab thiab cov iav kho kom zoo nkauj kom tau raws li cov xim sib txawv. Thiab nws cov xim tsis yooj yim hloov thaum lub sij hawm tag nrho cov txheej txheem ntawm iav. Lub caij no, nws pab txhim kho lub cev lub cev ntawm iav. Nws tuaj yeem txo qhov kub ntawm cov iav, uas yog qhov zoo rau molding ntawm qhov kub thiab txias, txuag lub zog thiab cov nqi thiab txo cov khoom siv. Nws kuj tseem tuaj yeem ua rau cov iav molecules zoo sib xws, txhim kho lub hardness thiab lub zog ntawm iav, ua rau iav ntau zog thiab ruaj khov thiab haum rau cov xwm txheej uas yuav tsum muaj lub zog siab xws li hauv architecture thiab tsheb. Ntxiv mus, nws muaj kev ruaj ntseg tshuaj zoo. Thaum ntxiv rau iav, nws tuaj yeem txhim khu kev tiv thaiv rau cov tshuaj xws li acids, alkalis thiab ntsev, nthuav dav daim ntawv thov ntawm iav. Tsis tas li ntawd, nws tuaj yeem siv los ua iav polishing khoom. Nrog nws cov hardness nruab nrab thiab kev sib tsoo zoo, nws tuaj yeem ua rau iav nto smoother thiab flatter, txhim kho cov smoothness thiab transparency ntawm iav. Tsis tas li ntawd, nws kuj muaj cov khoom fluorescent. Raws li qee qhov xwm txheej, nws tuaj yeem ua rau iav emit fluorescence, ua rau pom qhov txawv txav rau cov khoom iav thiab siv rau lub sijhawm tshwj xeeb xws li kho kom zoo nkauj thiab teeb pom kev zoo.
