Ib qho ntxiv, nws txuas ntxiv lub sijhawm qhib, muab cov ntawv sau ntau dua hauv kev tso chaw thiab kho cov ntoo vaj huam sib luag.
3.3 noo noo tsis kam
Wallpaper adhesives feem ntau ntsej muag noo noo-cuam tshuam, tshwj xeeb tshaj yog nyob rau hauv cov chaw xws li chav ua noj thiab chav dej. HPMC cov tshuaj ntxiv ntxiv rau cov ya raws tshuaj tiv thaiv ntawm cov nplaum, txo txoj kev pheej hmoo ntawm cov duab putring lossis deforming vim av noo.
Daim Ntawv Thov HPMC hauv Phab Ntsa
4.1 Kev Siv Nyob
Nyob rau hauv cov chaw nyob, cov nplaum nplaum uas muaj HPMC cov khoom ntxiv muaj cov npe nrov, txuas ntxiv qhib lub sijhawm thiab txhim khu kev qha adhesion. Cov tswv yim tau txais txiaj ntsig los ntawm cov ua kom tiav qhov durability thiab kev ua kom zoo nkauj ntawm daim duab npog nrog HPMC-muaj cov nplaum.
4.2 Kev lag luam thiab kev lag luam ib puag ncig
Kev lag luam thiab cov ntawv thov kev lag luam xav tau cov lus nplaum waller nrog cov yam ntxwv ua tau zoo. HPMC Additives ua tau raws li cov cai no los ntawm kev muab cov nyiaj sib xyaw ua ke muaj zog, ua kom pom tseeb ntawm ib puag ncig, ua rau lawv tsim nyog siv rau ntau qhov chaw lag luam.
Cov txiaj ntsig ntawm kev siv HPMC hauv cov nplaum nplaum
5.1 Txhim Kho Adhesion
Cov yeeb yaj kiab ua yeeb yam ntawm HPMC ua kom muaj kev sib txuam ntawm phab ntsa thiab substrate, tiv thaiv teeb meem xws li peeling lossis tev ua si.
5.2 Txhim Kho Kev Ua Haujlwm
HPMC RH RHEOG SUP tswj tso cai rau cov ntawv thov yooj yim thiab kev kho kom haum rau cov ntawv txheeb, ua cov txheej txheem teeb tsa kom muaj zog dua.
5.3 nce noo noo tsis kam
HPMC cov tshuaj ntxiv ua rau cov dej noo tsis kam ntawm cov nplaum ua kom haum, ua rau lawv haum rau cov kev siv hauv cov chaw muaj cov av noo.
5.4 Sijhawm Tos
Cov xuaj moos qhib tau muab los ntawm HPMC muab Installers ntau lub sij hawm rau txoj hauj lwm thiab kho cov phab ntsa, txo txoj hauv kev ua yuam kev thaum lub sij hawm teeb tsa.
Sau ntawv rau cov qauv
6.1 mauv nrog lwm cov kev sib ntxiv
