Lub hauv paus rau daim ntawv thov tuaj yeem yog cov av cib, pob zeb, ntoo, plaster, cov chaw uas yav dhau los pleev xim nrog alkyd thiab acrylic xim tsev, hlau, galvanized qhov chaw.
Txhob xeb
Yog tias nws yog qhov tsim nyog kom ua tiav cov xeb, kua yas nrog kua xeb hluav taws xob yog txheej txheem zoo hauv tshuab. Firstly, lub siab adhesion ntawm cov khoom siv no rau cov hlau ua rau nws tau kom nco ntsoov tias txheej yuav nyob twj ywm tsis hloov mus ntev. Qhov thib ob ntxiv yog tias koj tuaj yeem thov pleev xim ncaj qha rau xeb, yam tsis siv sijhawm los kho lub ntsej muag nrog tus primer thiab tos kom nws qhuav.
