Cov ntaub ntawv PVC yog cov khoom siv extruded ntau yam uas siv dav hauv kev tsim kho, kho kom zoo nkauj, kev lag luam thiab kev ua liaj ua teb. Lawv qhov nrov yog vim muaj kev siv nyiaj tsawg thiab hloov tau ntau qhov xwm txheej, tab sis kev ruaj khov ntawm kev ua haujlwm thiab lub neej ua haujlwm nyob ntawm cov khoom tseem ceeb xws li cov stabilizers.Cov stabilizers TopJoyua lub luag haujlwm tseem ceeb hauv kev daws cov teeb meem ntawm PVC profiles kom tau raws li ntau yam kev thov.
Cov ntaub ntawv PVC raug faib ua pawg raws li kev siv kom tau raws li qhov xav tau tshwj xeeb. Cov hom tseem ceeb suav nrog cov ntaub ntawv qhov rooj thiab qhov rai ntawm lub tsev (lub hauv paus rau kev tsim vaj tsev), cov ntaub ntawv kho kom zoo nkauj (cov laug cam, cov kab kho kom zoo nkauj rau kev ua tiav sab hauv), cov ntaub ntawv lag luam (cov ntaub thaiv khoom siv rau kev tiv thaiv) thiab cov ntaub ntawv ua liaj ua teb (cov thav tsev cog khoom rau kev cog qoob loo).
Cov profiles no muaj cov txiaj ntsig zoo: muaj zog tiv taus corrosion, lub teeb yuag rau kev teeb tsa yooj yim, zoo nkauj heev (ua qauv ntoo / pob zeb) thiab ruaj khov zoo. Txawm li cas los xij, cov kev txwv tsis pub dhau los ua rau muaj teeb meem ntawm kev siv - tsis kam tiv taus kub siab (softening saum 60 ° C), qis-kub brittleness (cracking hauv qab -10 ° C) thiab sab nraum zoov laus, uas txwv lawv siv hauv qhov chaw nyuaj.
Cov xwm txheej ntawm daim ntawv thov sib txawv muaj cov kev xav tau ua haujlwm tau zoo. Piv txwv li, kev tsim cov qhov rooj thiab qhov rai profiles yuav tsum tiv taus kev laus sab nraum zoov thiab kev hloov pauv kub, thaum cov profiles kev lag luam xav tau kev tiv taus cua sov kom hloov kho rau cov khoom siv ua haujlwm. Cov kev xav tau no tsim kom muaj kev xav tau ceev ceev rau cov kev daws teeb meem txhim khu kev qha.
TopJoy stabilizers muab cov kev daws teeb meem rau cov teeb meem no. Lawv txhim kho PVC profiles 'high/low kub tsis kam, tiv thaiv kev laus sab nraum zoov thiab tswj kev ruaj khov, txuas ntxiv lub neej kev pabcuam. Rau cov chaw tsim khoom, TopJoy cov kev daws teeb meem txhim khu kev qha pab tsim cov profiles zoo uas ua tau raws li cov kev xav tau tshwj xeeb, txhawb kev sib tw ua lag luam thiab kev ntseeg siab.
