Txhawm rau tiv thaiv cov xim me me los ntawm kev poob rau hauv lwm cov ntaub ntawv raw, txhua tus xim yuav tsum tau muab los ntawm lub thawv nrog nws tus kheej cov cuab yeej tshwj xeeb thiab hnyav ntawm cov nplais du thiab yooj yim-rau-huv, lossis ib daim ntawv yas yuav tsum muab tso rau. ntawm qhov ntsuas ua ntej rau qhov hnyav.
Yog li ntawd, rau cov khoom siv tshuaj lom neeg, tshwj xeeb tshaj yog cov khoom siv tshuaj lom neeg xws li arsenic dawb, iav fwj cov chaw tsim khoom yuav tsum muaj cov thawv ntim tshwj xeeb thiab cov txheej txheem kom tau txais thiab siv, thiab kev tswj hwm thiab siv cov txheej txheem thiab ua raws li cov kev cai thauj mus los. Rau cov khoom siv hluav taws xob thiab tawg, cov chaw tshwj xeeb yuav tsum tau teeb tsa, thiab lawv yuav tsum tau muab khaws cia thiab khaws cia cais raws li cov khoom siv tshuaj lom neeg ntawm cov khoom siv raw.
Nyob rau hauv loj thiab me mechanized iav factories, niaj hnub noj raw cov ntaub ntawv rau iav melting yog tsis tshua muaj neeg loj, thiab raw khoom xaiv thiab ua khoom siv feem ntau yuav tsum tau. Yog li ntawd, nws yog ib qho tsim nyog rau cov tuam txhab iav fwj kom paub txog kev siv tshuab, automation, thiab sealing systematization ntawm raw khoom ua, cia, thauj thiab siv.
Lub rooj cob qhia kev npaj cov khoom siv raw thiab batching rhiav yuav tsum tau nruab nrog cov khoom cua zoo thiab ntxuav tsis tu ncua kom huab cua hauv lub Hoobkas huv si txhua lub sijhawm kom ua tau raws li kev huv. Txhua qhov kev cob qhia uas khaws qee qhov kev sib xyaw ntawm cov ntaub ntawv yuav tsum tau nruab nrog cov tshuaj tsuag thiab cov khoom siv pa tawm, thiab cov neeg ua haujlwm yuav tsum hnav lub qhov ncauj qhov ntswg thiab cov cuab yeej tiv thaiv thiab tau kuaj xyuas lub cev tsis tu ncua los tiv thaiv silica deposition.
