PVC foaming tus neeg sawv cev cov khoom yog dawb, tab sis qee zaum lawv tig daj thaum khaws cia rau lub sijhawm ntev. Yog vim li cas?

Ua ntej, koj yuav tsum txiav txim siab seb puas muaj teeb meem nrog tus neeg sawv cev foaming xaiv. PVC foaming regulator siv cov foaming tus neeg saib xyuas kom decompose thiab tsim cov roj uas ua rau cov pores. Thaum cov txheej txheem kub tuaj yeem ncav cuag qhov kub ntawm qhov decomposition ntawm tus neeg sawv cev foaming, nws yuav tsis ua npuas ncauj. Ntau hom foaming agents muaj qhov sib txawv decomposition kub, txawm tias tib hom foaming agent yog tsim los ntawm cov tuam txhab sib txawv, qhov decomposition kub yuav tsis zoo ib yam. Xaiv cov PVC foaming regulator uas haum rau koj. Tsis yog txhua tus PVC yog tsim rau foaming, yog li nws yog ib qho tsim nyog yuav tau xaiv cov ntaub ntawv uas tsis tshua muaj polymerization degree. Cov ntaub ntawv zoo li no muaj qhov ua haujlwm qis, xws li S700. Yog tias koj xav siv 1000 thiab 700, nws yuav txawv. Tus neeg sawv cev foaming yuav tau decomposed thiab PVC tseem tsis tau yaj.

Tsis tas li ntawd, muaj lwm yam additives. Lub decomposition kub ntawm ib txwm foaming tus neeg sawv cev yog siab tshaj qhov ua kub ntawm PVC. Yog hais tias tsim nyog additives tsis ntxiv, qhov tshwm sim yog tias PVC decomposes (dub daj los yog dub) thiab ACR tseem tsis tau decomposed (ua npuas ncauj). Yog li ntawd, nws yog ib qho tsim nyog yuav tau ntxiv cov stabilizers kom PVC ruaj khov (tsis decompose ntawm qhov ntsuas kub ntawm AC). Ntawm qhov tod tes, additives uas txhawb AC foaming yog ntxiv los txo qhov decomposition kub ntawm AC thiab phim nws. Kuj tseem muaj cov khoom siv ntxiv los ua kom cov npuas pores me me thiab ntom, uas yog kom tsis txhob ua npuas ncauj loj thiab txo lub zog ntawm cov khoom. Txij li thaum qhov kub tsis tshua muaj thiab tsis hloov daj, kuv tuaj yeem paub tseeb tias koj qhov kub siab dhau los ua rau PVC decompose thiab tig daj. PVC decomposition yog ib qho kev txhawb nqa tus kheej, uas txhais tau hais tias cov khoom decomposed txhawb ntxiv decomposition. Yog li ntawd, nws feem ntau pom tau tias nws yog qhov zoo yog tias qhov ntsuas kub tsis siab, tab sis yog tias qhov kub thiab txias me ntsis, nws yuav decompose nyob rau hauv ntau qhov ntau.
