Hoʻolauna
Hoʻohana ʻia ʻo PVC ma ke ʻano he plastik ākea me ka hua nui loa a me ka laulā noi ākea ma ka honua.Ua hoʻohana nui ʻia i nā ʻano e like me ke kūkulu hale, nā huahana ʻoihana, nā paipu i hoʻohana ʻia i kēlā me kēia lā, nā mea hoʻopaʻa paʻa, nā fibers, etc.Eia nō naʻe, pili ka resin PVC i nā mea brittle.ʻAʻole hiki i kāna māhele aniani hoʻomau ke pale i ka hoʻonui nui ʻana o nā māwae ma lalo o ke koʻikoʻi a loaʻa i nā āpau a me ka naha ʻana.No laila, ʻo ia ʻano mea e hōʻike ana i ka hopena maikaʻi ʻole.Eia nō naʻe, hiki ke hoʻopau ʻia kēia hemahema e ka hoʻohui ʻana i ka hoʻololi ʻana i ka hopena i loko o nā mea PVC i ka wā o kā lākou hana ʻana a me ke kaʻina hana.
Pono e hōʻike ʻia nā mea hoʻololi hopena maikaʻi e ka hahai ʻana i nā waiwai maikaʻi:
(1) He haʻahaʻa haʻahaʻa vitrification wela Tg;
(2) Ke kūpono o ka hoʻololi ʻana i ka hopena me ka resin PVC;
(3) Hoʻohālikelike ka viscosity o nā mea hoʻololi hopena me PVC;
(4) ʻAʻohe hopena maikaʻi ʻole i nā mea i ʻike ʻia a me nā waiwai kino a me nā ʻenehana o PVC;
(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.
Aia ʻo ACR a me MBS i kahi ʻano hoʻololi i ka hopena copolymer "core-shell".Hana ʻia kona kumu ma ke ʻano he elastomer cross-linked haʻahaʻa, e pāʻani ana i nā kuleana nui i ka hoʻonui ʻana i ka tenacity a me ka pale ʻana i ka hopena.ʻO kona pūpū he polymer kiʻekiʻe-molecular me kahi wela vitrification kiʻekiʻe, e pāʻani ana i nā kuleana nui i ka pale ʻana i ke kumu lāʻau a hoʻomaikaʻi i ka hoʻohālikelike ʻana me PVC.He mea maʻalahi ke hoʻokaʻawale ʻia kēia ʻano o nā ʻāpana hoʻololi a hiki ke hoʻopuehu ʻia i loko o ka matrix PVC i mea e hana ai i kahi ʻano "mokupuni moana".Ke hoʻopili ʻia ka mea i ka hopena o waho, hiki ke hoʻololi ʻia nā ʻāpana me ka modulus haʻahaʻa.I ka manawa like, hoʻokumu ʻia ka de-bonding a me ka lua e like me ka mea i alakaʻi ʻia e ka PVC deformation me kahi modulus kiʻekiʻe.Inā hoʻokumu ʻia kēlā mau puka kokoke, hiki i ka papa matrix ma waena o nā ʻāpana lāʻau ke hāʻawi a hoʻonui i ka ikaika o ka mea.Hōʻike ʻia ke kumu kūʻē i ka hopena ma ke kiʻi ma lalo nei.
Hōʻike ka CPE, ACR a me MBS i ka ʻokoʻa o ka naʻau i ka ikaika mīkini ma muli o kā lākou ʻano hana paʻakikī.I ka wā o ka hana ʻana, hoʻokaʻawale ʻia nā ʻāpana ACR a me MBS i loko o ka PVC matrix ma o ka ʻohi ʻana, e hana ana i kahi ʻano "mokupuni moana" a pēlā e hoʻonui ai i ka ikaika o ka mea.ʻOiai inā e piʻi aʻe ka ikaika o ka hoʻoponopono ʻana, ʻaʻole hiki ke hoʻololi maʻalahi kēia hale.Hiki ke hoʻokō ʻia ka hopena paʻakikī maikaʻi loa e like me ka hoʻololi ʻana o CPE a me PVC i hui pū ʻia i loko o kahi ʻōnaehana pūnaewele e hoʻopili ana i nā ʻāpana PVC mua.Eia nō naʻe, hiki ke hoʻololi maʻalahi kēia ʻano pūnaewele ma muli o nā loli i ka ikaika o ka hana.No laila, ʻoluʻolu ia i ka ikaika o ka hana ʻana a pili i kahi ʻano hana liʻiliʻi.

Hōʻike ke kiʻikuhi ma lalo nei i ka pihi rheological.Laina ʻulaʻula: ADX-600/3phr+CPE/3phr;laina polū: CPE/9phr
ʻO nā torques kaulike o nā mea ʻelua he ʻano like ia, a ʻo ka plastification o nā mea i hoʻololi ʻia e ADX-600/3PHr + CPE/3PHR ʻoi aku ka mālie akā i loko o ka mana e like me ke kiʻi.No laila, ma ke ʻano o ka hoʻoili ʻana, hiki i nā 3 doses o ADX-600 me 3 doses o CPE ke hoʻololi i ka hoʻohana ʻana o 9 doses o CPE.
III.Nā hopena
Ma o ka hoʻohālikelike ʻana ma waena o ka ADX-600 AIM a me ka CPE a me MBS i nā waiwai mechanical a me nā ʻano hana, ua huki ʻia ka hopena ma hope o ka nānā ʻana i ka manaʻo e hiki ke hoʻololi i ka hoʻohana ʻana o 9 doses o CPE me 3 dosis o ADX-600 a me 3 mau puʻupuʻu o CPE. .Hōʻike ʻo ADX-600 AIM i ka hana piha ʻoi aku ka maikaʻi, nona nā huahana e hōʻike ana i ka hana ʻoi aku ka maikaʻi a me ka hana ʻoi aku ka maikaʻi.
Aia ka ADC-600 AIM i kahi copolymer acrylate me ka hoʻokumu ʻia ʻana o ka pūpū.Hōʻike ʻo ACR i ka ʻoi aku ka maikaʻi o ka pale ʻana i ka wā, ka paʻa wela a me ka lakio kumu kūʻai hana ma mua o MBS no ka mea ʻaʻohe paʻa pālua i ka mua.Eia kekahi, hōʻike pū ʻo ACR i nā mea maikaʻi o ka laulā kaʻina hana, ka wikiwiki extrusion wikiwiki, ka mana maʻalahi, a me nā mea ʻē aʻe. nā paipu paipu, nā papa, nā mea hoʻohāhā, a me nā mea ʻē aʻe. He ʻano hoʻololi i ka hopena me ka nui o ka nui i kēia manawa a me ka hiki ke ulu nui i ka wā e hiki mai ana.
