Qhov cuam tshuam hloov pauv ACM yog qhov sib cuam tshuam network copolymer ntawm HDPE thiab acrylate nrog lub teeb chlorination - ACM resin. Nws kov yeej qhov tsis muaj zog ntawm cov iav siab hloov pauv qhov kub thiab qhov tsis zoo ntawm CPE, thiab muaj qhov cuam tshuam rau kev hloov pauv ntawm qhov kub thiab txias.
Txoj kev siv ACM yog tib yam li CPE. Thaum siv, extruder tam sim no thiab torque yuav txo me ntsis. Tus nqi ntawm cov roj nplua nyeem sab nraud yuav tsum raug txo kom txog thaum tam sim no thiab lub zog ntawm ACM zoo ib yam lossis siab dua me ntsis ntawm CPE.
Qhov ntsuas kub tsis tshua muaj qhov cuam tshuam lub zog ntawm PVC cov khoom hloov kho los ntawm PVC cuam tshuam kev hloov pauv yog cuam tshuam nrog kev hloov pauv iav ntawm PVC cuam tshuam kev hloov pauv. Qhov qis dua qhov hloov pauv iav yog, qhov siab dua qhov kub ntawm qhov cuam tshuam lub zog yog. Ob leeg CPE thiab cuam tshuam ACR hloov kho PVC cov khoom muaj cov qauv hiav txwv hiav txwv. Thaum qhov kev faib ua feem ntawm lub hiav txwv kob qauv yog tib yam, lub toughness ntawm PVC cov khoom muaj feem xyuam rau lub Vicat softening point ntawm marine theem. Qhov qis dua Vicat softening point ntawm marine theem, qhov zoo dua qhov toughness ntawm cov khoom. Lub Vicat softening point ntawm marine theem ntawm PVC cov khoom muaj feem xyuam rau cov qauv molecular ntawm PVC cuam tshuam hloov. Linear polymers tuaj yeem tawg mus rau hauv PVC theem nyob rau hauv lub xeev molecular, uas txo cov intermolecular quab yuam ntawm PVC, yog li txo cov Vicat softening point ntawm PVC thiab zoo heev nce toughness ntawm PVC khoom.
Kev sib piv ntawm qhov cuam tshuam tshiab hloov pauv ACM thiab ib txwm muaj acrylate impact modifier. Qhov ntsuas kub tsis tshua muaj zog ntawm qhov cuam tshuam tshiab hloov pauv ACM yog siab dua li ntawm CPE ib txwm muaj, qhov elongation ntawm kev so kuj siab dua CPE, thiab Vicat softening point yog qis dua CPE. Yog li ntawd, peb tuaj yeem xav tias cov khoom siv PVC hloov kho los ntawm kev hloov pauv tshiab tsis yog tsuas yog muaj qhov cuam tshuam zoo ntawm qhov kub thiab txias, tab sis kuj muaj qhov zoo ntawm chav sov toughness, thiab zoo heev thermal stability thiab UV tsis kam. Tus tshiab cuam tshuam hloov pauv yog qhov zoo tshaj plaws cuam tshuam tus neeg sawv cev rau PVC.
