Resin: PVC feem ntau siv hom 8 resin, uas muaj gelation ceev ceev thaum lub sij hawm ua, kuj tsis tshua muaj kub ua, ruaj khov khoom zoo, thiab yooj yim ceev tswj.Nyob rau hauv xyoo tas los no, ntau manufacturers tau hloov mus rau hom 5 resin.
Stabilizer: Kev xaiv ntawm stabilizer, suav nrog kev tiv thaiv ib puag ncig thiab cov txiaj ntsig zoo ntawm qhov nyiam tsis tshua muaj lub ntiaj teb stabilizer, tab sis vim yog tus nqi siab, tsis tau nce qib, yav tom ntej nrog kev tiv thaiv ib puag ncig kom nce, lub ntiaj teb tsis tshua muaj kev lag luam stabilizer yuav coj mus rau hauv ci ntsa iab kev cia siab.Calcium zinc stabilizer muaj zinc hlawv teeb meem thiab cov nyhuv stability yog me ntsis tsis zoo thiab tus nqi tsawg.Tam sim no, feem ntau siv los yog lead ntsev stabilizer, ua npuas ncauj pawg thawj coj saib vim cov pwm hla ntu yog dav, qhov ntws channel ntev thiab daj ua npuas dej decomposition tshav kub ntau lawm, lub stabilizer yuav tsum muaj cov ntsiab lus txhuas siab thiab zoo stability, txwv tsis pub. cov khoom yog nquag muaj ntau yam teeb meem.
Tshuab tshuab: xaiv tus neeg sawv cev tshuab, tshuab tshuab AC hauv cov txheej txheem decomposition tso tawm ntau cov cua sov, yooj yim ua rau nruab nrab ntawm cov seem daj, uas yuav tsum tau muaj qee yam ntawm cov tshuab tshuab dawb, decomposition plays lub luag hauj lwm ntawm absorbing tshaj. Thaum tshav kub kub lub zog, yuav tsum muaj tus naj npawb ntawm cov tshuab tshuab kom loj, thiaj li ua tiav cov foaming tsis muaj qhov npuas loj.
Regulator: foaming regulator, dhau xyoo ntawm kev tshawb fawb thiab kev tsim kho thiab kev txhim kho, cov txheej txheem thev naus laus zis ntawm foaming regulator ACR tau dhau los ua neeg paub tab, thiab kev ua haujlwm zoo tau nce thiab ruaj khov.Raws li lub thickness ntawm foaming board, daim ntawv yuav tsum tau plasticized ceev, thiab cov tuab board yuav tsum tau plasticized qeeb tov muaj zog foaming regulator.
Lubricants: Kev xaiv cov roj nplua nyeem ua raws li lub hauv paus ntsiab lus ntawm cov roj lubrication thaum ntxov, nruab nrab thiab lig, kom cov ntaub ntawv muaj kev tiv thaiv los ntawm lubricants ntawm txhua theem, thiab ua raws li cov khoom ruaj khov mus ntev yam tsis muaj fouling.
Foaming auxiliaries: Txhawm rau txhim kho foaming zoo thiab ua npuas ncauj qauv, ib qho me me ntawm foaming auxiliaries zinc oxide tuaj yeem muab ntxiv rau hauv kev tsim khoom, thiab ib qho me me ntawm txhuas silicate tuaj yeem muab ntxiv txhawm rau txo cov nag lossis daus.
Pigments: Txhawm rau kom ua tiav cov txiaj ntsig zoo nkauj dua, titanium dioxide thiab fluorescent whitening agents tuaj yeem ntxiv, thiab antioxidants thiab ultraviolet absorbers tuaj yeem muab ntxiv los txhim kho huab cua tiv thaiv.
Filler: Kev xaiv ntawm lub teeb calcium carbonate tuaj yeem ua tau, tsis tas siv cov calcium uas nquag siv, xaiv cov mesh loj.
Lub thermoplastic high-molecular polymer ua los ntawm kev ncua polymerization ntawm vinyl chloride monomer.Cov mis mos molecular:- (CH2 - CHCl) n - (N: degree ntawm polymerization, N = 590 ~ 1500).Nws yog cov khoom siv dav dav siv hauv kev tsim khoom yas.Nws muaj kev ruaj ntseg tshuaj zoo, corrosion kuj thiab dej tsis kam.
