Cov txheej txheem filling ntawm iav dej lub raj mis
Raws li ib puag ncig tus phooj ywg, tu cev, thiab txhim khu kev qha cov tshuaj tua kab mob, cov txheej txheem tsim cov iav dej fwj thiab cov kaus poom yog nruj heev thiab ceev faj. Hauv qab no, peb yuav qhia txog cov txheej txheem tsim cov iav dej fwj thiab cov kaus poom.
Ua ntej, cov neeg tsim khoom yuav tsum xaiv cov khoom siv zoo, feem ntau yog borosilicate iav. Hom iav no muaj cov yam ntxwv ntawm qhov kub thiab txias tsis kam, acid thiab alkali tsis kam, thiab nws yog qhov tsim nyog rau kev ua dej haus fwj thiab cov kaus poom.
Qhov thib ob, cov khoom siv raw xaiv raug xa mus rau lub khob rauv rau melting, nrog rau qhov kub thiab txias feem ntau nyob ib ncig ntawm 1500 degree. Tom qab cov txheej txheem ntawm kev ua tiav thiab kev hloov kho, cov iav fwj uas ua tau raws li cov qauv tuaj yeem tau txais.
Tom qab ntawd, muab lub raj mis tso rau hauv lub tshuab kev tshaj lij rau molding. Nws yuav tsum raug sau tseg tias qhov tseeb ntawm molding yog qhov tseem ceeb rau kev ua haujlwm tom ntej, vim tsuas yog zoo meej molding tuaj yeem ua kom cov polishing thiab ci.
Tom ntej no, lub khob iav yuav tsum tau polished thiab polished ua tib zoo, vim tias tsis tsim nyog polishing tuaj yeem cuam tshuam qhov zoo thiab zoo nkauj ntawm lub thawv, thaum kawg cuam tshuam rau cov khoom muag.
Thaum kawg, kev kho ci yog ua tiav, thiab lub sijhawm ci thiab qhov kub thiab txias kuj tseem ceeb heev, uas tuaj yeem ua rau lub khob ntim tau cov yam ntxwv xws li kub tsis kam, tawg tsis kam, thiab kev tu cev.
Hauv luv luv, cov txheej txheem tsim cov iav dej fwj thiab cov kaus poom yog cov txheej txheem nruj uas yuav tsum tau ua tib zoo saib xyuas txhua yam, thiab tsuas yog hauv txoj kev no peb tuaj yeem tsim cov khoom uas ua tau raws li qhov yuav tsum tau ua, tiv thaiv tib neeg lub neej thiab kev noj qab haus huv.
