Thaum lub sijhawm ua cov khoom PVC tawv, qhov teeb meem xim kuj yog ib qho teeb meem uas tshwm sim ntau thiab ntau yam uas nyuaj rau daws thaum lub stabilizer hloov ntawm cov ntsev txhuas mus rau calcium zinc stabilizer. Nws cov tsos mob suav nrog cov hauv qab no:
1. Kev hloov cov tshuaj stabilizer ua rau cov xim ntawm cov khoom hloov pauv. Tom qab hloov cov tshuaj stabilizer los ntawm cov ntsev txhuas mus rau cov tshuaj calcium zinc stabilizer, nws yooj yim pom tias cov xim ntawm cov khoom feem ntau yog xim ntsuab, thiab nws nyuaj rau ua tiav kev hloov xim ntawm ntsuab mus rau liab.
2. Cov xim ntawm cov khoom sab hauv thiab sab nraud tsis sib xws tom qab siv calcium zinc stabilizer. Feem ntau, cov xim sab nraud zoo nkauj, thaum cov xim sab hauv feem ntau yog xiav-ntsuab thiab daj. Qhov xwm txheej no tuaj yeem tshwm sim tau yooj yim hauv cov profiles thiab cov kav dej.
3. Cov xim ntawm cov khoom thaum lub sijhawm ua tiav tom qab siv cov tshuaj calcium zinc stabilizers. Hauv cov txheej txheem ntawm kev siv cov tshuaj txhuas ntsev stabilizers los ua cov khoom, tej zaum yuav muaj qee qhov kev hloov pauv xim ntawm cov tshuab sib txawv thiab ntawm lub sijhawm sib txawv hauv tib lub tshuab, tab sis qhov kev hloov pauv ntau yam yog qhov nqaim heev. Tom qab siv cov tshuaj calcium zinc stabilizers, qhov kev hloov pauv no yuav loj dua, thiab qhov cuam tshuam ntawm kev hloov pauv me me hauv cov khoom siv raw thiab cov txheej txheem ntawm cov xim kuj tseem yuav pom tseeb dua. Tus sau tau ntsib tus kheej cov xwm txheej uas cov neeg siv khoom siv cov tshuaj calcium zinc stabilizers los tsim cov kav dej thiab cov khoom siv, thiab kev hloov pauv siab tsis tsuas yog cuam tshuam rau xim ntawm cov khoom, tab sis kuj cuam tshuam rau nws cov kev ua tau zoo. Qhov kev hloov pauv no muaj kev cuam tshuam ntau dua li thaum siv cov tshuaj txhuas ntsev stabilizers.
4. Qhov teeb meem xim ntawm cov khoom thaum lub sijhawm khaws cia, thauj mus los, thiab siv tom qab siv calcium zinc cov tshuaj stabilizers uas tsis ua rau ib puag ncig puas tsuaj. Cov khoom PVC tawv siv cov tshuaj stabilizers ntsev txhuas ib txwm muaj kev hloov xim me ntsis thaum khaws cia, thauj mus los, thiab siv. Tom qab hloov mus rau cov tshuaj stabilizers uas tsis ua rau ib puag ncig puas tsuaj xws li calcium thiab zinc, tej zaum yuav muaj qhov nyiam rau cov khoom kom tig daj thiab xiav tom qab sawv. Qee cov tshuaj stabilizers yuav ua rau cov khoom tig liab thaum siv rau cov khoom uas muaj cov hlau ion ntau hauv cov hmoov calcium.
Qhov laj thawj tseem ceeb rau cov teeb meem xim saum toj no yog tias cov qauv ntawm calcium zinc stabilizers yog qhov nyuaj heev, thiab qhov thermal stability hauv theem thaum ntxov, nruab nrab, thiab tom qab ntawd tau ua tiav los ntawm kev sib koom tes ntawm ntau yam khoom siv raw. Txhua yam khoom muaj qee yam cuam tshuam rau xim ntawm cov khoom, thiab kev sib xyaw ua ke ntawm ntau yam khoom tsim ntau yam ua tau. Tib lub sijhawm, kev nyuaj siab ntawm kev ua lag luam tau ua rau qee cov chaw tsim khoom stabilizer siv cov khoom siv raw tsis ua raws li txoj cai, uas ua rau qhov nyuaj ntawm qhov teeb meem ntxiv zuj zus. Txhawm rau daws qhov teeb meem kom meej, nws tsis yog tsuas yog tsim nyog los tshuaj xyuas cov teeb meem tshwj xeeb, tab sis kuj tseem yuav tsum xaiv cov lag luam PVC hauv qab kom zoo zoo xaiv cov lag luam loj dua thiab cov npe nrov.
Kev sib piv qhov sib txawv tseem ceeb: Cov tshuaj stabilizers ua los ntawm cov ntsev txhuas tau siv dav vim lawv cov khoom siv hluav taws xob zoo heev thiab tus nqi qis, tab sis lawv muaj teeb meem nrog kev lom ntau thiab cov plua plav paug.
