Lub npe tag nrho ntawm PVC yog PVC.Nws cov viscosity ntws kub yog ze heev rau qhov degradation kub, yog li nws yooj yim los tshwm sim ntau hom degradation thaum ua, yog li poob kev siv.Yog li ntawd, thaum tshav kub kub stabilizer thiab lubricant yuav tsum tau ntxiv rau cov qauv ntawm PVC cov khoom xyaw.Tus qub txhim kho nws cov thermal stability, thaum lub tom kawg txo qhov kev sib txhuam ntawm PVC molecular chains, nrog rau kev tso tawm quab yuam ntawm PVC yaj thiab hlau, thiaj li los txhim kho kev yooj yim ntawm kev ua PVC rau hauv ntau yam khoom. Polyethylene wax thiab oxidized polyethylene ciab yog cov roj nplua nyeem hauv PVC.

Thaum lub sij hawm ua cov PVC, tsis muaj cov ntshiab yaj, tsuas yog cov khoom nruab nrab (100 μ M, uas yog tsim los ntawm cov khoom tseem ceeb thiab cov nodules) faib ua cov pob me me (1 μ M los yog li ntawd), thiab tom qab ntawd faib ua cov nodules (100nm).Cov txheej txheem no feem ntau hu ua gel lossis plasticization.Txhawm rau kom ua tiav cov khoom siv kho tshuab zoo dua, cov khoom nto thiab cov txheej txheem ua tiav, qib ntawm gel yog tsim nyog ntawm 70% thiab 85%.Kev xaiv kom zoo ntawm polyethylene wax tuaj yeem ncua lossis ua kom cov txheej txheem gel.Homopoly polyethylene wax muaj nyob nruab nrab ntawm cov ntsiab lus los yog cov nodules tom qab melting, txo cov kev sib txhuam ntawm cov thawj hais los yog nodules, yog li txo cov kev sib txhuam kub tsim ntawm yaj, ncua lub plasticization ntawm PVC, thiab kev txhim kho thermal stability ntawm PVC.Covope uamuaj qee yam kev sib raug zoo nrog PVC, uas tuaj yeem txuas rau saum npoo ntawm nodules, ua kom cov viscosity yaj, thiab me ntsis txhawb cov gel cwj pwm;

Nws lwm lub luag haujlwm tseem ceeb yog tsim ib qho zaj duab xis ntawm PVC yaj thiab hlau nto los txo qhov kev sib txhuam ntawm cov yaj thiab cov khoom siv ua haujlwm.Nws yog ib tug zoo pwm tso tus neeg sawv cev nyob rau hauv PVC ua, tshwj xeeb tshaj yog nyob rau hauv pob tshab PVC (organic tin stabilizer) zaj duab xis.Ntxiv qhov tsim nyog ntawm oxidized polyethylene wax tuaj yeem ua tsis tau tsuas yog ua tiav cov pwm tso tawm, tab sis kuj tsis txo qhov pom tseeb.

Tam sim no, ntxiv rau hluavtawspe wax thiab ope ciab nyob rau hauv PVC, paraffin wax, Fischer Tropsch wax thiab by-product wax kuj tau dav siv, uas kuj yuav tsum tau flexibly matched raws li daim ntawv thov davhlau ya nyob twg.Piv txwv li, tsis tshua muaj melting point paraffin tuaj yeem ua lub luag haujlwm hauv lubrication thaum ntxov, nruab nrab melting point polyethylene wax thiab Fischer Tropsch wax tuaj yeem ua lub luag haujlwm hauv nruab nrab lubrication, thiab siab melting point oxidized polyethylene wax tuaj yeem ua lub luag haujlwm hauv lub sijhawm lubrication.Qee cov roj nplua nyeem uas tsis muaj qhov kub thiab txias, xws li paraffin wax thiab fatty acid ester, yog ib qho yooj yim rau tso rau ntawm lub taub hau tuag ntawm cov khoom extruded thiab txias yob ntawm calendering zaj duab xis.Cov tshuaj no yuav muaj kev cuam tshuam tsis zoo rau qhov ua tau zoo ntawm cov khoom kawg, nrog rau qhov chaw ua haujlwm thiab kev tsim cov neeg ua haujlwm ntawm qhov chaw.

Ntxiv mus, kev sib raug zoo ntawm ib lub roj nplua nyeem hauv PVC yog siab heev.Yog tias siv cov pob zeb sib xyaw ua ke, ntau yam khoom sib xyaw ua ke tsis sib haum thiab ua rau muaj kev sib haum xeeb, uas kuj yooj yim rau kev sib cais siab.Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau xaiv cov roj nplua nyeem uas muaj qhov ruaj khov thiab zoo kub tsis kam raws li cov khoom siv, xws li kev luam ntawv thiab tshuaj tsuag yuav tsum tau ua, rau kev tsim khoom zoo thiab txhim kho cov khoom zoo.
