- 1.PVC resin hmoov
Nws yog cov khoom siv tseem ceeb, cov khoom siv foaming, ua PVC foamed ntawv feem ntau txais yuav Model SG-8 PVC resin.Thaum ua tiav, gelatinization ceev ceev, kev ua haujlwm kub yog qhov qis, cov khoom zoo ruaj khov, thiab qhov ceev yog yooj yim los tswj.Txhawm rau txhim kho cov khoom zoo thiab nruj me ntsis tswj qhov kev hloov pauv ntawm cov khoom ntom ntom thiab tuab, SG-8 PVC resin feem ntau yog siv los tsim cov npuas dawb thiab Celuka ua npuas ncauj PVC los xij.
- 2.PVC stabilizer
Txhawm rau kom ua tiav cov khoom siv hauv cov txheej txheem ntawm PVC ua npuas ncauj, cov khoom siv feem ntau yog kub.Tsis tas li ntawd, tus neeg sawv cev foaming kuj ua rau decomposition tshav kub nyob rau hauv tus txheej txheem ntawm decomposition.Cov yam tseem ceeb no xav kom cov stabilizer muaj cov thermal stability txaus los xyuas kom meej cov khoom zoo thiab cov khoom ruaj khov mus ntev. - 3.Foaming regulator
Nws yog tsim los ntawm methyl methacrylate, ethyl acrylate, butyl acrylate, thiab styrene.Nws cov qauv molecular yog ib tug core-plhaub qauv.Raws li kev pab cuam hauv kev tsim cov txheej txheem, nws tuaj yeem txo qhov kub ntawm plasticizing, txhawb cov nyhuv plasticizing, txhim kho cov plasticizing efficiency, txhim kho cov yaj lub zog, txo cov yaj pulsation, tiv thaiv cov yaj tawg, thiab txhim kho qhov smoothness ntawm cov khoom. .Lub hauv paus ntsiab lus xaiv ntawm foaming regulator muaj xws li plasticizing ceev, yaj lub zog, thiab yaj fluidity.Vim hais tias ntawm cov txheej txheem sib txawv, cov qauv foaming regulator yuav tsum raug xaiv raws li ntau yam khoom ntiag tug yam ntxwv, xws li cov ntawv foamed, tuab foamed ntawv, nyias foamed ntawv, ntoo yas foamed ntawv, thiab lwm yam. Lawv tuaj yeem xyuas kom meej qhov sib xws ntawm cov yaj thiab zoo. board nto zoo.Tsis tas li ntawd, peb yuav tsum xaiv cov khoom zoo sab hauv thiab sab nraud thiab ntxiv cov cua sov kom txaus rau cov mis. - 4.Foaming agent
Tus neeg sawv cev foaming yog cov khoom siv uas ua rau cov khoom siv rau hauv cov qauv ntawm tes.Nws tuaj yeem muab faib ua cov tshuaj foaming agent, lub cev foaming tus neeg saib xyuas, thiab surfactant.Nws yog tsuas yog siv los tswj qhov ceev thiab ntsuas ntawm PVC foaming boards. - 5. Filler
Hauv cov qauv txheej txheem, qhov dav dav ntawm lub teeb calcium carbonate yog 10 ~ 40 phr.Filler tuaj yeem tsis tsuas yog siv los ua tus neeg sawv cev foaming nucleating tab sis kuj txo cov nqi khoom.Txawm li cas los xij, kev siv ntau dhau ntawm lub teeb calcium carbonate yuav ua rau lub cev tsis sib xws ntawm tes, ces cuam tshuam rau cov tsos thiab cov khoom zoo.Nws thaum kawg ua rau cov khoom ntom ntom tsis yooj yim rau kev tswj, nce tus nqi tag nrho, thiab txo cov khoom hardness. - 6. Pigment
Nws yog siv rau xim lub rooj tsavxwm, feem ntau yog dawb, liab, daj, xiav, ntsuab, dub, grey, thiab lwm yam.
