Lub tshuab hloov cov ntoo siv lub tshuab nqus tsev nqus kom ua tiav xa daim ntawv xa mus rau lub chaw ua haujlwm. Qhov no hloov pauv cov txheej txheem nyuaj ntawm phau ntawv gluing, phau ntawv nplaum, phau ntawv tev, ntxuav phau ntawv, thiab phau ntawv polishing. Txo tus nqi hloov pauv, tus nqi ntawm cov khoom hloov pauv yog nruab nrab ntawm 3-5 yuan.
Rau cov khoom ua haujlwm nrog cov qauv sib sib zog nqus, cov cuab yeej tau nruab nrog cov phaj silica gel. Yog li txhua qhov chaw tuaj yeem nqus tau rau hauv qhov chaw, txo qhov to. Rau cov qauv ua haujlwm ntiav thiab tiaj tus, cov cuab yeej tau nruab nrog daim ntaub silica gel. Piv nrog rau cov phaj silica gel, lub neej ua haujlwm ntawm daim ntaub silicone yog ntev dua.
Rau cov khoom ua haujlwm nrog cov qauv sib sib zog nqus thiab cov phaj tuab, qhov siab thaum hloov pauv tuaj yeem tsim nyog. Ua kom ntseeg tau tias thawj qhov chaw tuaj yeem nqus tau qhov chaw. Rau cov khoom ua haujlwm nrog cov qauv ntiav thiab cov phaj nyias, lub siab thaum hloov pauv tsis tuaj yeem nce ntxiv, uas yuav ua rau deformation ntawm cov haujlwm.
Yog hais tias sab ntawm lub cev ua haujlwm yuav tsum tau hloov chaw, nws yuav tsum tau txhuam nrog cov kua nplaum. Ua lub luag haujlwm ntawm kho daim ntawv xa mus.
