Lub luag haujlwm ntawm PVC foaming regulator

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm PVC foaming regulator yog ua tiav los ntawm kev tswj cov khoom siv lub cev thiab tshuaj ntawm PVC yaj. Cov haujlwm tshwj xeeb yog raws li nram no:
1. Txhawb kev ua kom yas thiab yaj sib npaug
Cov saw hlau ntev ntawm cov tshuaj tswj kev ua npuas ncauj (ACR) ua kom cov khoom yas sai dua los ntawm kev ntswj cov saw hlau PVC, txo qhov kub ua tiav, thiab tsim cov qauv gel network. Cov txheej txheem no tsis yog tsuas yog ua kom nrawm dua qhov ceev yaj, tab sis kuj txhawb kev sib xyaw ua ke ntawm cov khoom ntxiv thiab cov neeg sawv cev ua npuas ncauj, txo cov qhov tsis zoo sab hauv hauv cov yaj.
2. Txhim kho lub zog thiab elasticity ntawm yaj
Cov qauv peb-seem uas tsim los ntawm kev sib txuas ntawm cov saw hlau molecular ua rau lub zog ntawm cov yaj zoo dua, ua rau nws muaj peev xwm encapsulate roj thiab tiv thaiv cov cell coalescence thaum lub sijhawm ua npuas ncauj. Tib lub sijhawm, nws muab cov yaj nrog elasticity, cia cov qhov hws nthuav dav thiab ntsws sib npaug, tswj cov qauv cell kaw.
3. Tswj qhov sib npaug ntawm viscoelasticity ntawm cov yaj
Tus tswj hwm kho qhov viscoelasticity ntawm PVC yaj, ntev lub sijhawm ua npuas dej, thiab phim qhov nrawm ntawm cov neeg sawv cev ua npuas dej nrog qhov nrawm ntawm cov roj diffusion. Qhov kev tswj hwm no tuaj yeem txo qhov nrawm ntawm cov npuas tawg (raws li pom hauv cov ntaub ntawv sim, qhov nrawm ntawm kev tawg tau txo qis los ntawm 25% mus rau 8%) thiab ua kom zoo dua qhov sib xws ntawm cov roj faib hauv cov yaj.
4. Txhim kho cov qauv pore thiab kev ruaj khov
Qhov kev txhim kho lub zog yaj thiab elasticity tuaj yeem tiv thaiv kev tawg ntawm cov qhov hws sib ze, tsim cov qauv me me thiab sib xws. Cov tswj hwm nrog qhov hnyav molecular siab dua, xws li HL530, tuaj yeem txo qhov ceev ntawm cov khoom, thaum tswj hwm qhov fluidity ntawm cov saw hlau molecular kom tiv thaiv kev tawg ntawm cov qhov hws los ntawm kev so ntau dhau.
5. Txhim kho qhov chaw thiab cov khoom siv kho tshuab ntawm cov khoom
Qhov kev txhim kho ntawm qhov sib xws ntawm cov yaj txo cov cim ntws ntawm qhov chaw thiab cov qhov tsis zoo ntawm qhov ntsws, thiab ua kom qhov chaw huv si. Qhov kev nce ntawm lub zog yaj tsis ncaj qha ua rau muaj kev tiv thaiv kev cuam tshuam thiab kev ruaj khov ntawm cov khoom.
Hauv kev xaus lus, nws lub hauv paus ntsiab lus ntawm kev ua haujlwm yog qhov tseem ceeb kom ua tiav kev tswj hwm qhov tseeb ntawm lub zog yaj, viscoelasticity, thiab kinetics ua npuas ncauj los ntawm kev sib txuas lub cev thiab cov teebmeem tshuaj lom neeg, yog li sib npaug ntawm cov cell ceev, kev ncaj ncees ntawm cov qauv, thiab kev ua haujlwm zoo.
