Cov khoom siv ua ACR raug ntxiv thaum lub sijhawm ua yas, uas tuaj yeem muab cov khoom siv lub cev ntawm cov khoom. Yuav ua li cas txhim kho kev ua tau zoo ntawm cov khoom?
1. Txhawb cov khoom siv ua kom yas: Hom no siv dav hauv cov khoom PVC tawv, feem ntau yog txhawb kev ua kom yas, txhim kho cov khoom rheological yaj, txhim kho kev sib kis ntawm lwm cov khoom ntxiv, thiab txhim kho qhov zoo ntawm cov khoom.
Haum rau feem ntau cov khoom PVC xws li cov profile, cov kav dej, cov phaj (yob), thiab lwm yam, nrog rau qhov siv tshuaj ntawm 1-2 phr.
2. Tus tswj kev ua npuas ncauj: ACR cov khoom pab ua haujlwm, vim nws qhov hnyav molecular siab, tuaj yeem txhim kho lub zog yaj ntawm PVC cov ntaub ntawv, zoo encapsulate foaming roj, tsim cov qauv honeycomb sib xws, thiab tiv thaiv cov roj kom tsis txhob khiav tawm. Tib lub sijhawm, ACR cov khoom pab ua haujlwm kuj tseem muaj txiaj ntsig zoo rau kev sib kis ntawm lwm cov khoom ntxiv suav nrog cov neeg sawv cev ua npuas ncauj, txhim kho qhov zoo ntawm cov khoom thiab txhim kho qhov ci ntsa iab.
Haum rau cov laug cam ua npuas ncauj, cov pas nrig ua npuas ncauj, cov kav dej ua npuas ncauj, cov qauv ua npuas ncauj, cov yas ntoo ua npuas ncauj, thiab lwm yam, nrog rau qhov siv tshuaj ntawm 4-8 phr
3. Kev pab ua kom lubricating sab nraud: Nws muaj cov khoom zoo ib yam li cov hlau stripping zoo li oxidized polyethylene wax, tab sis qhov sib txawv yog tias nws muaj kev sib raug zoo nrog PVC, tuaj yeem ua kom cov yas ua haujlwm tau zoo dua rau qee qhov, txhim kho cov khoom rheological yaj, thiab tsis hloov pauv qhov kub ua haujlwm thaum lub sijhawm extrusion. Nws tiv thaiv cov teebmeem haze los ntawm cov roj nplua nyeem hauv cov khoom pob tshab.
Haum rau cov qauv lossis cov khoom siv uas xav tau cov txheej txheem siab, tshwj xeeb tshaj yog rau cov ntawv pob tshab, cov ntaub ntawv ua npuas ncauj, cov laug cam ua npuas ncauj, thiab cov yas ntoo ua npuas ncauj. Cov koob tshuaj siv yog 0.5-2phr.
