Cov kev siv thiab kev ceev faj ntawm PVC foaming regulator yog dab tsi?

Kev siv cov PVC foaming regulator:

Qhov ua npuas dej ntawm cov khoom siv PVC yog ua kom cov khoom faib tawm ntawm PVC sib npaug zoo dua. Ua kom zoo ntawm cov khoom PVC zoo dua. Cov ntawv PVC ua npuas dej los ntawm PVC foaming regulator muaj cov qauv ywj pheej zoo heev. Qee zaum, thaum siv PVC foaming regulator, peb kuj siv qee cov foaming accelerators. Foaming accelerators suav nrog cov hlau oxides xws li zinc oxide thiab lead oxide, cov ntsev organic acid xws li zinc stearate, thiab urea derivatives.

Qhov zoo ntawm PVC foaming regulator:

Cov tshuaj tswj ua npuas dej PVC muaj tag nrho cov yam ntxwv ntawm cov khoom siv ua PVC, nrog rau qhov hnyav molecular siab dua li cov khoom siv ua PVC. Ntxiv cov tshuaj tswj ua npuas dej PVC kom tsim nyog thaum lub sijhawm ua cov khoom PVC tuaj yeem txhim kho lub zog ntawm cov yaj thiab tiv thaiv kev puas tsuaj.kev ua npuas dej. Tib lub sijhawm, nws kuj tseem tuaj yeem muaj cov nyhuv yas zoo. Lub hom phiaj yog xyuas kom meej tias cov yaj muaj cov kua dej zoo.

Cov kev ceev faj rau kev siv PVC foaming regulator:

Thaum siv cov khoom siv ua npuas ncauj PVC, nws yog ib qho tseem ceeb uas yuav tsum tau them sai sai rau cov khoom PVC uas muaj ntau theem ntawm polymerization thiab xaiv cov khoom siv ua npuas ncauj sib txawv. Cov khoom ua npuas ncauj yas suav nrog cov laug cam ua npuas ncauj, cov laug cam tuab ua npuas ncauj, cov laug cam nyias ua npuas ncauj, cov laug cam ntoo ua npuas ncauj yas, cov laug cam ua npuas ncauj yas txhuas, thiab lwm yam. Vim tias cov khoom ntxiv ua npuas ncauj PVC kuj yog cov tshuaj acrylic uas muaj cov khoom pab ua tiav, yuav tsum tau them sai sai rau qhov sib npaug ntawm cov roj nplua nyeem sab hauv thiab sab nraud ntawm cov mis thaum siv lawv.

Cov ntsiab lus tseem ceeb ntawm kev tswj cov txheej txheem ua npuas dej PVC:

Kev ua npuas yas ua npuas muab faib ua peb txoj kev: tsim cov npuas hauv plawv, nthuav dav ntawm cov npuas hauv plawv, thiab khov ntawm lub cev ua npuas. Rau cov ntawv ua npuas PVC nrog cov tshuaj ua npuas ntxiv, qhov nthuav dav ntawm cov npuas nuclei muaj qhov cuam tshuam loj rau qhov zoo ntawm cov ntawv ua npuas. PVC yog cov molecule ncaj nrog cov saw luv luv thiab lub zog yaj qis. Thaum lub sijhawm ua cov npuas hauv plawv nthuav dav mus rau hauv cov npuas, qhov yaj tsis txaus los npog cov npuas, thiab cov pa roj yooj yim ntws thiab sib xyaw ua ke rau hauv cov npuas loj, txo qhov zoo ntawm cov ntawv ua npuas.
