cov khoom

piav qhia luv luv:

Cov khoom siv raw no yog siv los ua cov acrylic waterborne sealant rau kev txhaws qhov sib koom ua ke hauv tsev. Cov sealant tsev yog cov nplaum tsev uas muaj cov nplaum hauv paus, cov khoom sau, cov neeg ua kom khov thiab lwm yam khoom ntxiv. Tom qab raug cuam tshuam, khov ua cov roj hmab elastic thiab sib txuas nrog cov khoom siv hauv paus tsev. Nws ua lub luag haujlwm ntawm kev kaw, tsis muaj dej thiab tsis xau, thiab feem ntau yog siv rau kev kaw qhov sib koom ua ke ntawm cov tsev. Ua cov nplaum tsev, nws txawv ntawm lwm cov nplaum tsev xws li kua nplaum hauv daim ntawv thiab kev siv. Lwm cov nplaum tsev feem ntau yog kua thiab feem ntau yog siv rau kev sib txuas thiab lo cov khoom kho kom zoo nkauj tsev yam tsis muaj kev cuam tshuam sealing. Vim yog tus nqi siab ntawm cov roj hmab silicone, nws tau siv rau kev txhaws hauv tsev, uas ua rau tus nqi engineering nce ntxiv. Hom no tuaj yeem hloov pauv tag nrho kom txo tus nqi. Tus nqi ntawm cov sealant no txawv raws li qhov xav tau ntawm ntau qib. Nws muaj cov yam ntxwv ntawm kev rov qab siab, tiv taus dej, tiv taus kub qis thiab muaj zog nplaum.
