Cov kev ua haujlwm zoo tshaj plaws ntawm cov khoom siv raw sib xyaw hauv cov txheej txheem ntawm PVC yas hlau cov pobzeb khoom siv yog sib xyaw txhua yam kev pabcuam hauv cov roj tusyees hauv PVC cob los ntawm cov khoom siv sib tov, kom cov koom haum tuaj yeem ua lub luag haujlwm thiab paub meej tias cov khoom lag luam muaj cov khoom zoo heev.
Rau qhov yooj yim sib xyaw ntawm PVC yas steel cov pobzeb khoom siv nyob rau hauv cov xwm txheej dav dav, cov khoom siv hmoov tsis tuaj yeem tsis sib kis thiab sib xyaw tusyees ntawm PVC cob, lawv yuav muaj nyob rau hauv kev sib xyaw ua ke hauv daim ntawv ntawm kev sib sau ua ke, thiab cov khoom siv ua npuas yas tsis tuaj yeem ua tsis tiav dispersed rau PVC cob.Hauv qab qhov kev txiav tawm ntawm cov khoom sib tov, PVC cov xaim hluav taws xob feem ntau tawg mus rau hauv thawj cov khoom, cov khoom siv sib xyaw ua ke yog cov khoom tawg ntxiv, thiab cov koom haum thiab cov resins ua me me cov morphologies nrog qhov loj dua qhov chaw uas yooj yim dua rau adsorb thiab" sib txuas" nrog txhua lwm yam. Hauv cov txheej txheem kev sib xyaw ntawm PVC yas steel cov pobzeb khoom siv, shear cov cua sov lossis / thiab cua sov sab nraud yuav ua rau kom qhov kub ntawm cov khoom sib xyaw, cov saw hlau ntawm PVC yuav dhau los ua haujlwm ntau ntxiv nrog qhov nce ntawm qhov kub thiab, thiab qhov qog ntawm qhov me me yuav nce , uas yooj yim rau cov diffusion thiab nqus ntawm cov yas thiab ua kom muaj zog ntawm kev pabcuam. Cov roj khov qis taw tes pabcuam, xws li cov khoom siv roj, yuav dhau los ua kua thaum qhov kub nce ntxiv thiab yuav tawg mus rau hauv lub qhov hws ntawm cov khoom tawg ua haujlwm zoo li lub hnab yas. Yog li ntawd, qhov tseem ceeb ntawm cov txheej txheem ntawm PVC yas steel cov nplais cov khoom siv cov txheej txheem yog tias dhau los ntawm kev sib xyaw kev kub ceev thiab cov ntaub ntawv raw tau mus txog rau qee qhov sib xyaw ua kom sov, cov txheej txheem ntawm cov qauv ntawm PVC tuaj yeem ua kab mob sib kis thiab sib tov sib xyaw, kom ntseeg tau tias tom ntej plasticizing ntawm cov ntaub ntawv thiab qhov sib xws ntawm molding.
