Cryolite belongs rau cov kab ke dawb monoclinic thiab yog me ntsis soluble hauv dej, thiab molten cryolite tuaj yeem yaj alumina. Cryolite feem ntau yog siv los ua flux hauv electrolytic aluminium kev lag luam. Nrog nws, milky dawb iav tuaj yeem tsim tau, thiab nws kuj yog ib qho opacifier rau enamel.

Cryolite siv:
Cryolite tuaj yeem siv los ua cov kuab tshuaj sib xyaw ua ke hauv aluminium electrolysis, thiab tuaj yeem siv los ua cov khoom hnav-tiv taus hauv cov khoom siv abrasive. Abrasives nrog cryolite ntxiv tau txhim kho kev sib tsoo quab yuam thiab txiav quab yuam, nrog rau kev pab cuam lub neej thiab lub sijhawm cia. Cryolite tuaj yeem siv los ua cov kuab tshuaj nyob rau hauv ferrous alloys, boiling steel, non-ferrous hlau, raws li ib tug deoxidizer nyob rau hauv casting, raws li ib tug catalyst nyob rau hauv lub polymerization ntawm alkenes, raws li ib tug anti-reflection txheej, nyob rau hauv iav, raws li ib tug emulsifier. Nws kuj yog siv rau hauv enamel, thiab nws kuj yog tus neeg sawv cev opalizing rau iav, flux rau vuam cov ntaub ntawv, muab tub lim rau kev lag luam ceramic, thiab lwm yam.
Lub hom phiaj tseem ceeb:
Cryolite tsim nyob rau hauv cov xwm yog tsawg heev, thiab feem ntau ntawm nws yog artificially siv nyob rau hauv kev lag luam. Cryolite yog siv los ua co-solvent, additive, deoxidizer, catalyst, emulsifier thiab muab tub lim nyob rau hauv txhuas electrolysis, sib tsoo khoom, ferroalloys, non-ferrous hlau, enamel, iav, ceramics thiab lwm yam teb.
Industrial Quality Requirements:
Cov teb uas muaj ntau tshaj plaws ntawm cryolite yog kev lag luam txhuas. Raws li cov flux rau electrolytic aluminium smelting, muaj cov kev cai nruj rau sodium-aluminium molecular ratio, impurity cov ntsiab lus, dej cov ntsiab lus thiab lwm yam qauv ntawm cryolite.

Ua ntej tshaj plaws, qhov siab dua qhov piv ntawm sodium rau aluminium hauv cryolite, qhov ua tau zoo ntawm electrolytic aluminium smelting tam sim no ntau dua, uas tuaj yeem txo qhov poob ntawm fluorine thiab ua rau muaj kuab paug tsawg dua rau ib puag ncig. Lub cryolite nrog siab polymer piv kuj haum rau kev lag luam tshem tawm txhuas. siv nyob rau hauv lwm yam lag luam.
Qhov thib ob, cov ntsiab lus ntawm impurities xws li silicon oxide, hlau oxide, thiab phosphorus pentoxide nyob rau hauv cryolite yuav tsum tau nruj me ntsis tswj, vim hais tias cov impurities yuav cuam tshuam qhov zoo ntawm txhuas ingots thiab tam sim no efficiency ntawm txhuas smelting.
Thaum kawg, tswj cov dej ntsiab lus ntawm cryolite, qhov qis cov ntsiab lus ntawm cov dej, qhov zoo dua, vim tias muaj cov dej yuav ua rau kom siv cov cryolite.
