Lub luag haujlwm tseem ceeb ntawm PVC foaming regulator hauv kev ua tiav yog feem ntau pom tseeb hauv cov hauv qab no:
1. Txhim kho lub zog thiab kev ruaj khov ntawm cov yaj
Txhim kho qhov kev sib koom ua ke thiab lub zog ntawm PVC yaj, ua rau cov yaj yaj ua tau zoo encapsulate foaming roj, tiv thaiv cov npuas coalescence, collapse lossis rupture, xyuas kom meej cov qauv cell sib xws thiab ntom, thiab yog li txhim kho qhov ceev thiab cov khoom siv kho tshuab ntawm cov khoom.
2. Txhim kho cov qauv pore
Los ntawm kev tswj hwm qhov viscoelasticity ntawm PVC yaj, tswj qhov ruaj khov ntawm cov qhov hws thaum lub sijhawm nthuav dav, txo cov roj tawm, tsim cov qauv microporous ywj pheej thiab sib xws, thiab txhim kho qhov ruaj khov thiab kev cuam tshuam ntawm cov khoom.
3. Txhawb kev ua kom yas thiab ua cov kua dej
Ua kom cov txheej txheem plasticization ntawm PVC resin sai dua, txo qhov kub ua tiav, kho qhov fluidity ntawm cov saw hlau molecular, txo qhov sib txhuam ntawm cov molecular, txhim kho qhov ductility ntawm yaj, ua kom yooj yim dua rau kev sau cov pwm nrog cov ntaub ntawv, thiab txhim kho qhov du ntawm qhov chaw.
4. Txhim kho qhov zoo ntawm qhov chaw thiab qhov ci ntsa iab
Txhawb kom muaj kev sib xyaw ua ke ntawm cov neeg ua npuas dej thiab lwm yam khoom ntxiv, txo qhov tsis zoo ntawm qhov chaw, ua kom cov laug cam ua npuas dej, cov kav dej thiab lwm yam khoom zoo li du thiab mos, thiab pab txhim kho cov khoom siv kho tshuab tag nrho.
5. Koom tes nrog lwm cov khoom siv ntxiv kom ua tau zoo tshaj plaws
Thaum siv ua ke nrog cov tshuaj stabilizers kub, kho qhov kub ntawm cov tshuaj foaming kom tsis txhob muaj kev tawg ua npuas dej los ntawm kev puas tsuaj hauv zos lossis kev ua kom tsis sib xws ntawm cov yas yaj, kom ntseeg tau tias cov txheej txheem tsim khoom ruaj khov.
