Nto Kho
Txhawm rau kom ua tiav lub zog siab tshaj plaws, nws yog qhov tseem ceeb kom ua kom huv si txoj kev sib raug zoo thiab tshem tawm cov roj lossis xeb siv acetone lossis trichlorethylene. Cawv, roj av, los yog ntoo qab zib yuav tsum tsis txhob siv rau kev ntxuav. Sandblasting lossis cov tshuab sib tsoo tuaj yeem ua haujlwm kom nce thaj tsam thaj tsam thiab txhim kho kev sib koom tes. Ib qho ntxiv, nws raug nquahu kom nrhiav cov lus qhia los ntawm peb lub tuam txhab cov kws tshaj lij rau cov tshuaj kho cov txheej txheem saum npoo av.

Kev tiv thaiv daim tawv nqaij ua ntej ua haujlwm thiab tom qab ntxuav tes |
Txhais tes qab zib los yog tshuaj pleev cov tshuaj pleev yuav tsum tau siv los ua cov yeeb yaj kiab tiv thaiv ntawm daim tawv nqaij |
Cov ntaub ntawv ntawm daim tawv nqaij
So cov ntaub ntawv nrog cov ntaub ntawv phuam so lossis ntsej muag ci thiab tom qab ntawd ntxuav nws nrog xab npum sov thiab tsis yog alkaline. Tsis txhob siv cov kuab tshuaj los ntxuav cov tawv nqaij kom tsis txhob ua xua.
Cov khoom siv nchuav rau hauv av
Tsuas yog siv xuab zeb lossis sawdust kom nqus cov ntaub ntawv. Koj tseem tuaj yeem siv cov khaub hlab muaj kev lag luam lossis muaj ntaub ntawv los so huv. Tsis txhob siv cov kuab tshuaj kom nchuav rau hauv av thiab huv si. Muaj kev pheej hmoo ntawm hluav taws.
Thawj pab kev cai
Thaum muaj kev sib tsoo nrog cov khaub ncaws, tawv tawv, lossis lawv cov pa tawm ntawm qhov chaw muaj kev cuam tshuam rau kev kho mob. Yog tias kev sib txaws ntawm lwm qhov chaw ntawm daim tawv nqaij, so nrog cov nqaij ntsej muag, ntxuav thaj chaw nrog dej sov thiab tshuaj ntxuav tes, thiab siv tshuaj pleev tes los tswj cov tawv nqaij. Yog tias tsis muaj kev xav, nrhiav kev pab kho mob thaum muaj xwm ceev. Ib qho ntxiv, yuav tsum xav txog cov muaj peev xwm hlawv thiab ua kom muaj kev phom sij kub siab, thiab ua kom muaj kev phom sij ua haujlwm thiab cov neeg teb xov tooj nyab xeeb.
