Daim ntawv thov txheej txheem ntawm Waterproof Coatings

Txoj kev thov kom raug ntawm cov txheej txheem dej tsis zoo yog qhov tseem ceeb hauv kev ua kom muaj kev tsim kho zoo. Tag nrho cov txheej txheem yuav tsum ua raws li cov txheej txheem txheej txheem kom ua tiav cov txheej txheem dej tsis sib xws, ua tiav, thiab ruaj khov.

Ua ntej thov, kev npaj saum npoo yog kauj ruam tseem ceeb tshaj plaws. Lub substrate yuav tsum yog cov khoom, du, thiab huv si, tsis muaj plua plav, roj, cov khoom xoob, lossis pom cov kab nrib pleb. Tej yam tsis xws luag yuav tsum tau kho thiab leveled ua ntej. Rau cov substrates uas absorbent heev, ua ntej - ntub dej los yog daim ntawv thov ntawm primer yuav tsum tau txhim khu adhesion.

Thaum lub sij hawm npaj cov khoom, sib tov thiab proportioning yuav tsum nruj me ntsis raws li cov khoom specifications. Cov dej- raws li cov txheej txheem yuav tsum tau nplawm kom huv si kom tsis txhob muaj kev sib cais lossis sib cais. Rau ob -cov khoom siv, cov khoom sib xyaw ua ke yog qhov yuav tsum tau ua, thiab cov khoom siv yuav tsum tau siv nyob rau hauv nws lub sijhawm ua haujlwm kom tsis txhob kho ntxov ntxov.

Nyob rau hauv daim ntawv thov theem, ib tug nyias - txheej multi- txheej txheej txheej yog feem ntau pom zoo. Txhua lub tsho tiv no yuav tsum tau siv sib npaug thiab tsis tuab heev. Cov txheej tom ntej yuav tsum tsuas yog siv tom qab ib qho dhau los tau qhuav tag, kom ntseeg tau tias muaj zog interlayer kev sib raug zoo. Cov kev taw qhia ntawm daim ntawv thov yuav tsum nyob twj ywm kom tsis txhob muaj cov chaw uas ploj lawm lossis tsis sib xws.

Kev saib xyuas tshwj xeeb yuav tsum tau muab rau cov ncauj lus kom ntxaws xws li cov ces kaum sab hauv thiab sab nraud, cov yeeb nkab nkag mus, thiab kev tsim cov pob qij txha. Cov ntsiab lus tsis muaj zog no yuav tsum tau ntxiv dag zog los siv cov ntaub npog ntxiv los yog cov txheej txheem hauv cheeb tsam ntxiv los txhim kho kev ntseeg tau ntawm cov dej tsis zoo thiab txo cov kev pheej hmoo ntawm cov dej xau.

Tom qab kev thov, kev kho kom zoo thiab kev tiv thaiv yog tsim nyog. Cov txheej yuav tsum tau tiv thaiv los ntawm kev khiav tsheb, hnyav hnyav, lossis dej raug dej ua ntej kev kho tag nrho. Qee qhov xwm txheej, kev sim ntsuas dej yuav raug ua kom paub tseeb tias kev ua haujlwm tsis zoo ntawm cov dej.

Zuag qhia tag nrho, daim ntawv thov txheej txheem ntawm waterproof coatings yuav tsum muaj kev sib koom tes tswj ntawm qhov chaw npaj, tuav cov ntaub ntawv, txheej daim ntawv thov, thiab nthuav dav ntxiv. Tsuas yog dhau los ntawm kev ua raws li cov qauv kev tsim kho tau ua tiav ntev - kev ua tau zoo ntawm cov dej tsis zoo thiab txhim khu kev qha.
