Cov yam tseem ceeb uas cuam tshuam rau kev ua tau zoo ntawm chlorinated polyethylene (CPE):

1. Cov ntsiab lus ntawm cov tshuaj chlorine
Qhov ntau thiab kev ua tau zoo: Cov ntsiab lus chlorine ntawm CPE feem ntau yog 25% -45%. Thaum cov ntsiab lus chlorine yog ≥ 35%, nws muaj cov khoom tua tus kheej (LOI ≥ 28%), thiab thaum nws tshaj 40%, qhov hluav taws kub tau zoo dua.
Kev ua haujlwm kub qis: Thaum cov ntsiab lus chlorine yog 30% -40%, cov khoom tseem tswj tau qhov yooj ywm ntawm -30 ℃.
2. Cov txheej txheem chlorine
Kev faib tawm ntawm cov tshuaj chlorine atom: CPE npaj los ntawm txoj kev daws teeb meem, txoj kev ncua lossis txoj kev sulfurization, qhov sib xws ntawm kev faib tawm ntawm cov tshuaj chlorine atom cuam tshuam rau nws qhov sib xws thiab cov khoom siv kho tshuab.
Microstructure: Qhov degree ntawm chlorination cuam tshuam rau qhov kub hloov pauv iav (Tg) ntawm CPE, thiab qhov kev ua haujlwm qis-kub yuav tsum tau soj ntsuam los ntawm kev tshuaj xyuas dynamic thermomechanical.
3. Kev hloov kho sib xyaw
PVC tawv: Kev sib xyaw CPE nrog PVC (ntxiv 5-15 qhov) tuaj yeem ua rau lub zog cuam tshuam nce 3-5 zaug thiab txhim kho kev tiv thaiv huab cua.
Kev sib xyaw ua ke ntawm cov nplaim taws: Cov tshuaj sib xyaw nrog magnesium hydroxide (Mg (OH) ₂) tuaj yeem txo qhov ceev ntawm cov pa luam yeeb thiab txhim kho kev ruaj khov ntawm thermal.
4. Lub kaw lus sulfurization
Kev sib txuas ntawm qhov ceev: Cov tshuaj Peroxides (xws li DCP) lossis cov neeg sawv cev thiourea vulcanizing tuaj yeem ua kom zoo dua qhov kev sib txuas ntawm CPE, txhim kho kev tiv thaiv roj thiab lub zog kho tshuab.
5. Kev sau thiab ua tiav
Cov khoom siv tsis muaj organic: Kev ntxiv cov pa roj carbon dub lossis titanium dioxide tuaj yeem hloov kho qhov conductivity thiab cov xim, tab sis kev ntxiv ntau dhau yuav txo qhov ductility.
Kub ua: Qhov kub ntawm CPE decomposition yog qhov siab heev, tab sis yuav tsum tsis txhob muaj qhov kub siab ua rau HCl catalytic dechlorination reaction.
6. Kev hloov pauv daim ntawv thov
Cov roj hmab tshwj xeeb: CPE nrog cov tshuaj chlorine ntawm 25% -35% yog qhov tsim nyog rau cov xwm txheej hluav taws kub xws li cov ntaub thaiv cable.
Kev hloov kho ABS: C-hom thiab AZ hom CPE tsim los ntawm Bontecn Group Tuam Tshoj tuaj yeem txhim kho qhov hluav taws kub thiab tiv thaiv dej ntws ntawm ABS, txo cov hluav taws kub siv.
