Hauv lub ntiaj teb nyuaj ntawm kev tsim kho sab hauv thiab cov ntaub ntawv siv hauv kev tsim kho, cov ntawv phab ntsa ua npuas ncauj tau txiav ib qho chaw tshwj xeeb rau nws cov qauv tshwj xeeb, kev rwb thaiv suab, thiab kev ua kom zoo nkauj. Hauv plawv ntawm nws qhov kev ua tau zoo tshwj xeeb yog ib qho khoom uas feem ntau tsis quav ntsej tab sis tseem ceeb: cov kua stabilizers. Cov khoom ntxiv tshwj xeeb no ua haujlwm ua lub hauv paus tseem ceeb hauv kev ua kom cov ntawv phab ntsa ua npuas ncauj ruaj khov, ua haujlwm tau zoo, thiab sib xws nrog ib puag ncig. Cia peb tshawb nrhiav cov haujlwm tseem ceeb uas ua rauCov kua PVC kub stabilizerqhov tseem ceeb hauv kev tsim khoom thiab daim ntawv thov ntawm cov ntawv phab ntsa ua npuas ncauj.
1. Kev Ruaj Ntseg Thermal: Tiv Thaiv Kev Hloov Pauv Los Ntawm Kub
Kev tsim cov ntawv phab ntsa ua npuas ncauj muaj cov txheej txheem kub siab, xws li extrusion thiab calendaring, uas tuaj yeem ncav cuag qhov kub txog li 200 ° C. Thaum lub sijhawm ua haujlwm no, cov polymer matrix ntawm cov ntawv phab ntsa muaj kev phom sij rau kev puas tsuaj thermal, ua rau muaj teeb meem xws li qhov chaw blistering, xim distortion, thiab cov qauv tsis muaj zog. Cov kua stabilizers ua haujlwm ua cov neeg saib xyuas thermal, cuam tshuam cov dawb radicals tsim los ntawm kev raug cua sov. Kev tshawb fawb los ntawm Wallcovering Manufacturers Association qhia tias yog tsis muaj cov stabilizers zoo, cov qauv ntawv phab ntsa ua npuas ncauj muaj kev txo qis 40% hauv lub zog tensile tom qab tsuas yog 15 feeb ntawm 180 ° C. Qhov sib piv, ntawv phab ntsa nrog optimizedcov kua dej ruaj khovcov qauv tsim khaws cia ntau dua 85% ntawm nws lub zog qub, ua kom ntseeg tau tias cov khoom siv tswj hwm nws cov duab thiab kev ncaj ncees thaum lub sijhawm teeb tsa thiab siv mus sij hawm ntev, txawm tias nyob rau hauv thaj chaw uas muaj kev hloov pauv kub siab, xws li chav ua noj lossis chav hnub ci.
2. Kev Tiv Thaiv Cov Qauv Ua Npuas Ncauj: Txhim Kho Kev Sib Xws thiab Kev Ruaj Ntseg ntawm Cov Cell
Qhov sib txawv ntawm cov qauv thiab qhov sib dua ntawm cov ntawv phab ntsa ua npuas dej vam khom rau cov ua npuas dej zoo. Cov kua stabilizers ua lub luag haujlwm tseem ceeb hauv kev tswj cov txheej txheem ua npuas dej, ua kom muaj cov qauv sib xws, kaw-cell. Los ntawm kev tswj hwm lub nucleation thiab kev loj hlob ntawm cov pa roj npuas, cov additives no tiv thaiv cov teeb meem xws li cell collapse, coalescence, lossis kev faib tsis sib xws. Piv txwv li, hauv kev tshawb fawb sib piv ntawm PVC-raws li foamed wallpaper, cov qauv nrog kua stabilizers tau pom tias 30% nce hauv cell ceev thiab 25% txo qis hauv cell loj sib txawv piv rau cov tsis muaj. Qhov no ua rau muaj cov qauv nto sib xws dua, txhim kho cov khoom rwb thaiv tsev, thiab txhim kho lub zog kho tshuab, ua rau cov ntawv phab ntsa tiv taus kev cuam tshuam thiab hnav.
Kev lag luam ntawv phab ntsa tab tom yuav muaj kev hloov pauv tshiab hauv kev siv tshuab, nrog rau cov tshuaj ua kom cov kua dej ruaj khov nyob rau pem hauv ntej ntawm kev tsim kho tshiab. Cov kws tshawb fawb tab tom tshawb nrhiavcov tshuaj stabilizer ntau yamuas muab cov khoom ruaj khov ib txwm muaj nrog cov txiaj ntsig ntxiv, xws li kev ua haujlwm tua kab mob, kev ntxuav tus kheej, lossis kev tiv thaiv UV zoo dua. Cov kev nce qib no tsis yog tsuas yog txhim kho kev ua haujlwm thiab lub neej ntev ntawm cov ntawv ntsa ua npuas ncauj xwb tab sis kuj qhib cov hauv kev tshiab rau kev siv sab hauv tsev. Tsis tas li ntawd, kev tsim cov khoom ruaj khov ntse uas tuaj yeem teb rau cov kev xav ntawm ib puag ncig, xws li kev hloov pauv kub lossis av noo, tuav cov lus cog tseg ntawm kev tsim cov ntaub ntawv ntawv phab ntsa uas tuaj yeem hloov kho lawv cov yam ntxwv kom tau raws li qhov xav tau ntawm ntau qhov chaw sib txawv.
Xaus lus, cov tshuaj ua kom ruaj khov tsis yog tsuas yog cov khoom ntxiv xwb; lawv yog cov tseem ceeb uas ua rau cov ntawv phab ntsa ua npuas dej ua haujlwm tau zoo, ntseeg tau, thiab ruaj khov. Raws li qhov kev thov rau cov ntaub ntawv tsim kho kom zoo nkauj sab hauv tsev uas zoo rau ib puag ncig tseem nce ntxiv, lub luag haujlwm ntawm cov tshuaj ua kom ruaj khov yuav tsuas yog qhov tseem ceeb dua, tsav tsheb tsim kho tshiab thiab tsim lub neej yav tom ntej ntawm kev lag luam ntawv phab ntsa.
