ACR, PVC ua kev pab, muaj me me tab sis muaj txiaj ntsig loj. Koj puas paub?

Nyob rau hauv cov nqe lus ntawm pawg, PVC kev pab ACR tuaj yeem muab faib ua peb pawg:

1. Cov khoom siv ua haujlwm uas txhawb nqa plasticization: Hom kev pabcuam no yog siv dav hauv cov khoom siv PVC nruj. Nws lub luag haujlwm tseem ceeb yog los txhawb kev tsim cov yas, txhim kho cov khoom rheological ntawm cov yaj thiab txhim kho cov khoom tawg ntawm lwm cov khoom ntxiv, thiab txhim kho qhov pom tseeb ntawm cov khoom.

Haum rau feem ntau cov khoom siv PVC xws li profiles, kav dej, daim hlau (rolls), thiab lwm yam., siv ntau npaum li cas yog 1-2phr

2. Foaming regulator: Vim nws qhov hnyav molecular, PVC foaming regulator tuaj yeem ua rau lub zog yaj ntawm PVC cov ntaub ntawv zoo heev, yog li qhwv cov roj foaming zoo thiab tsim cov qauv honeycomb zoo los tiv thaiv cov roj los ntawm kev khiav tawm. PVC foaming regulator kuj muaj txiaj ntsig zoo rau kev tawg ntawm lwm cov khoom ntxiv nrog rau cov neeg ua npuas ncauj, txhim kho cov khoom zoo ntawm cov khoom thiab ua kom gloss.

Haum rau cov nplooj ntawv foamed, foamed rods, foamed kav, foamed profiles, foamed ntoo yas, thiab lwm yam. Qhov kev siv ntau npaum li cas yog 4-8phr.

3. Sab nraud lubricating kev pab: Nws muaj tib yam zoo hlau stripping zog raws li oxidized polyethylene wax. Qhov txawv yog tias nws muaj kev sib raug zoo nrog PVC. Rau ib qho twg, nws tuaj yeem ua kom cov txheej txheem plasticizing kev ua tau zoo thiab txhim kho cov yaj. Rheological zog, thiab lub qhov hluav taws xob expansion tseem tsis hloov thaum lub sij hawm extrusion ua, tsis hloov lub thermoforming zog, thiab tiv thaiv cov nyhuv haze los ntawm lubricant nag lossis daus nyob rau hauv cov khoom pob tshab.

Nws yog tsim rau cov qauv los yog cov khoom siv nrog kev ua haujlwm siab, tshwj xeeb tshaj yog cov ntawv pob tshab, ua npuas ncauj profiles, ua npuas ncauj thiab foamed ntoo yas, thiab lwm yam. Kev siv ntau npaum 0.5-2phr

Tshwj xeeb rau cov txheej txheem thiab cov khoom, cov yaj elasticity tuaj yeem txhim kho thaum lub sij hawm calendering, tso cai rau cov khoom seem rau dov smoothly ntawm ob lub rollers; qhov pom tseeb zoo tuaj yeem txhim kho thaum lub sij hawm cov yeeb nkab extrusion, tshem tawm qhov tshwm sim ntawm "shark skin", thiab nce tus nqi extrusion; Thaum lub sij hawm pob tshab extrusion, tus naj npawb ntawm "ntses ob lub qhov muag" hauv cov khoom tuaj yeem txo qis heev; Thaum lub sij hawm txhaj tshuaj molding, cov yaj elasticity yog nce, yog li txo qhov kev txhaj tshuaj ntim, txo qhov "dawb kab" tshwm sim, nce gloss nto, thiab txhim kho vuam lub zog. Yog hais tias lubricity ntxiv Kev pab cuam tuaj yeem txhim kho qhov kev ua tau zoo, ua kom lub voj voog txhaj tshuaj thiab ua kom cov zis ntau ntxiv, thiab tiv thaiv qhov tshwm sim ntawm "blooming" tshwm sim los ntawm sab nraud slippage; Thaum lub sij hawm tshuab molding, lawv tuaj yeem txhim kho plasticization, txo qhov tshwm sim ntawm qhov muag, txhim kho yaj elasticity, thiab ua kom cov molding thickness ntau dua.
