(5) He kū'ē maikaʻi i ka wā a me ka waiwai pehu.

ʻO nā mea hoʻololi maʻamau no ka PVC paʻakikī e uhi nui i ka chlorinated polyethylene (CPE), acrylate (ACR), ethylene-vinyl acetate copolymer (EVA), methyl methacrylate-butadiene-styrene ternary graft copolymer (MBS) a me acrylonitrile-butadiene-styrene copolymer (ABS copolymer). ).Ma waena o lākou, ua hoʻohana nui ʻia ka chlorinated polyethylene impact modifier ma Kina a ke hoʻohana nui ʻia nei ka acrylate ma muli o kāna mau waiwai maikaʻi.Ua lilo ia i mea hopohopo nui pehea e hoʻomaikaʻi ai i ka hopena o ka hopena a me ka maʻalahi o ka extrusion o ka plastic.
Hiki i kā mākou huahana AIM ADX-600 ke pani i ka CPE a me MBS.Hiki iā ia ke hoʻomaikaʻi nui i ka fluidity a me ka deformation thermal o PVC hehee a pēlā e hoʻomaʻamaʻa ai i ka plastic plastication.Hōʻike nā huahana hopena i ka ikaika hopena kiʻekiʻe a me ke kūpaʻa maikaʻi o ke aniau, kūpaʻa a me ka hana ʻana i ka waiwai me ka ʻili maikaʻi, nani a nani loa.A laila, ua loiloi mākou i ka ACR, CPE a me MBS ma nā ʻaoʻao aʻe.

I. Mechanism of Toughening by PVC Impact Modifiers

Hoʻohana ʻia ka polyethylene chlorinated (CPE) ma ke ʻano he mau molekala laina i hoʻopuehu ʻia i loko o ka matrix PVC ma kahi ʻano pūnaewele.ʻO ke kumu o ka pale ʻana i ka hopena ʻo ka hana ʻana i kahi pūnaewele elastic i loko o nā mea matrix PVC i mea e pale aku ai i ka hopena o waho.Hiki ke hoʻololi ʻia kēlā ʻano pūnaewele ma lalo o ka ikaika tensile.ʻO kēia ka mea e hoʻoulu ai i ka shear slip o ka hui ʻana ma kahi kihi o 30 ° a 45 ° mai ka ʻaoʻao tensile, pēlā e hoʻokumu ai i kahi ʻāpana ʻāʻī, e komo i ka nui o ka ikehu deformation, a hoʻonui i ka tenacity o ka ʻōnaehana hui.Hōʻike ʻia nā hoʻololi ʻana i ka hoʻoulu ʻana o nā mea ma lalo o ka ikaika o waho.
