Cov txiaj ntsig ntawm kev ntxiv ACR rau cov khoom PVC

Ntxiv ACR (acrylic processing aid) rau cov khoom PVC muaj ntau qhov zoo, raws li qhia hauv qab no:
1、 Kev ua haujlwm zoo dua
Ua kom lub sijhawm yas luv dua:
ACR cuam tshuam nrog PVC cov saw hlau los ntawm cov pab pawg polar, txo cov kev sib txhuam ntawm cov khoom me me, ua rau lub sijhawm yas yaj luv dua, thiab txhim kho kev ua haujlwm ntau lawm.
Txhim kho cov dej ntws tau zoo:
Ua kom zoo dua qhov flowability ntawm PVC yaj, txo cov kev hloov pauv torque thaum lub sijhawm ua tiav, thiab ua rau qhov chaw ntawm cov khoom du thiab muag dua.
Txhawb kom muaj kev sib npaug ntawm cov yas:
ACR tuaj yeem txo cov qhov ntxhib thiab cov npuas thiab txhim kho qhov sib xws ntawm cov khoom rau cov txheej txheem xws li extrusion thiab dov.
2. Kev txhim kho kev ua haujlwm ntawm lub cev
Kev tiv thaiv kev cuam tshuam thiab kev tawv nqaij kub qis: Lub hauv paus / plhaub qauv ntawm ACR tuaj yeem nqus tau lub zog cuam tshuam, txhim kho kev tiv thaiv kev cuam tshuam ntawm cov khoom, thiab txhim kho kev tawv nqaij hauv qhov chaw kub qis.
Kev tiv thaiv huab cua thiab kev ruaj khov: Txhim kho kev kam rau siab ntawm PVC rau cov yam ntxwv ib puag ncig xws li ultraviolet radiation thiab oxidation, thiab txuas ntxiv lub neej ua haujlwm ntawm cov khoom.
Kev txhim kho qhov du ntawm qhov chaw: ua rau qhov chaw ntawm cov khoom du thiab mos dua, txhim kho nws qhov kev zoo nkauj.
3, Kev txhim kho cov txheej txheem ua haujlwm
Txo kev siv hluav taws xob: Txo kev siv hluav taws xob ntawm cov khoom siv thiab txo cov nqi tsim khoom.
Kev txhim kho kev sib raug zoo: sib koom ua ke nrog cov plasticizers sib txawv kom tsis txhob muaj cov plasticizer los nag thiab tswj kev ywj pheej ntawm cov khoom.
4, Kev nthuav dav ntawm thaj chaw thov
Cov khoom PVC tawv, xws li cov qhov rooj thiab qhov rai profile, cov kav dej, thiab lwm yam, xav tau kev txhim kho lub zog cuam tshuam thiab kev tiv thaiv huab cua.
Cov khoom PVC mos: txhim kho kev ywj pheej thiab lub zog tensile, thaum txo cov plasticizers siv.
Cov xwm txheej tshwj xeeb ua tiav: ACR qhov hnyav molecular qis yog qhov tsim nyog rau kev sau cov khoom nyias-phab ntsa, thaum cov khoom hnyav molecular siab txhim kho lub zog yaj.
sau ua kom luv luv
ACR, ua ib qho khoom siv yas uas sib xyaw ua ke kev hloov kho thiab kev txhim kho kev ua haujlwm ntawm lub cev, yog siv dav hauv ntau qhov chaw ntawm cov khoom PVC, tshwj xeeb tshaj yog rau cov xwm txheej uas muaj kev xav tau kev ua haujlwm siab.
