ʻO ka resin no ka hana ʻana i nā ʻōnaʻi plastik PVC he polyvinyl chloride resin (PVC).ʻO ka polyvinyl chloride he polymer i hana ʻia me ka monomer vinyl chloride.

Hiki ke hoʻokaʻawale ʻia ka resin PVC i ʻelua ʻano, kahi ʻano wehe (XS) a me kahi ʻano paʻa (XJ), ma muli o ka dispersing agent i ka polymerization.ʻO 0.1-0.2mm ka nui o ka ʻōpala, ʻaʻole maʻamau ka ʻili, porous, like me ka pulupulu, maʻalahi ke komo i ka plasticizer, ʻoi aku ka liʻiliʻi o ka nui ma mua o 0.1mm, ʻoi aku ka maʻamau, paʻa, papa tennis, paʻakikī ke komo i ka plasticizer. i kēia manawa, hoʻohana ʻia nā ʻano ʻokoʻa.

Hiki ke hoʻokaʻawale ʻia ka PVC i ka papa maʻamau (PVC toxic) a me ka papa maʻemaʻe (PVC non-toxic).Pono ka papa maʻemaʻe i ka ʻike vinyl chloride (VC) ma lalo o 10 × 10-6, hiki ke hoʻohana ʻia i ka meaʻai a me ka lāʻau lapaʻau.ʻO nā kaʻina hana synthetic like ʻole, hiki ke hoʻokaʻawale ʻia ka PVC i ka suspension PVC a me ka emulsion PVC.Wahi a ka National Standard GB/T5761-93 "Inspection standard for general-purpose polyvinyl chloride resin for suspension method", ua mahele ʻia ke ʻano o ka hoʻokuʻu ʻana PVC i PVC-SG1 a i PVC-SG8 ʻewalu mau ʻano resins, kahi i emi ai ka helu. ʻoi aku ka nui o ka polymerization, ʻoi aku ka paona molekala ʻO ka nui o ka ikaika, ʻoi aku ka kiʻekiʻe o ke kahe hehee, a ʻoi aku ka paʻakikī o ka hana.

Ke koho ʻana i kahi huahana palupalu, PVC-SG1, PVC-SG2, a me PVC-SG3 e hoʻohana pinepine ʻia, a pono e hoʻohui ʻia ka nui o ka plasticizer.No ka laʻana, hana ʻia kahi kiʻiʻoniʻoni polyvinyl chloride me SG-2 resin, a hoʻohui ʻia 50 a 80 mau ʻāpana o ka plasticizer.I ka hana ʻana i nā huahana paʻakikī, ʻaʻole i hoʻohui ʻia a hoʻohui ʻia nā plasticizer i nā mea liʻiliʻi, no laila hoʻohana ʻia ʻo PVC-SG4, PVC-SG5, PVC-SG6, PVC-SG7, a me PVC-SG8.

No ka laʻana, hoʻohana ʻia ka resin SG-4 no ka paipu paʻakikī PVC, hoʻohana ʻia ka resin SG-5 no ka puka plastik a me ka ʻike puka makani, hoʻohana ʻia ka resin SG-6 no ke kiʻiʻoniʻoni ʻalohi, a hoʻohana ʻia ka resin SG-7 a me SG-8 no ka laʻana. ʻaoʻao huʻa paʻakikī.Hoʻohana nui ʻia ke ʻano emulsion PVC paste no ka ʻili artificial, wallpaper, ʻili papahele a me nā huahana plastik.Hoʻouna kekahi mau mea hana resin PVC i ka resin PVC e like me ke kiʻekiʻe o ka polymerization (ʻo ke degere o ka polymerization ka helu o nā loulou hui, ʻo ke degere o ka polymerization i hoʻonui ʻia e ke kaumaha mole o ke kaulahao e like me ke kaumaha molekala o ka polymer), e like me PVC resin i hana ʻia e Shandong Qilu Petrochemical Plant, nā huahana hale hana ʻO S-700;S-800;S-1000;S-1100;S-1200.

ʻO ka resin SG-5 he degere o ka polymerization mai 1,000 a 1,100.ʻO ka pauka PVC he pauka keʻokeʻo i loaʻa ka mānoanoa ma waena o 1.35 a me 1.45 g/cm3 a me ka mānoanoa o 0.4 a 0.5 g/cm3.Manaʻo mākou i ka ʻike o nā plasticizers i nā huahana PVC e like me nā huahana palupalu a paʻakikī.ʻO ka maʻamau, ʻo ka mea plasticizer he 0 ~ 5 mau ʻāpana no nā huahana paʻakikī, 5 ~ 25 ʻāpana no nā huahana semi-paʻakikī, a ʻoi aku ma mua o 25 mau ʻāpana no nā huahana palupalu.

ʻO Zibo Junhai Chemical ka mea hoʻolako nui o Pvc Resin.Hiki iā mākou ke hāʻawi iā PVC Resin S3, PVC Resin SG5, PVC Resin SG8, ​​PVC Resin S700, PVC Resin S1000, PVC Resin S1300 ext.A mai nā mea hana kiʻekiʻe o Kina, e like me Erdos PVC Resin, Sinopec PVC Resin, Beiyuan PVC Resin, Xinfa PVC Resin, Zhong tai PVC Resin, Tianye PVC Resin.ext.

Loaʻa i ka Polyvinyl chloride nā hiʻohiʻona koʻikoʻi o ka nui o nā mea maka (ʻaila, limestone, coke, paʻakai a me ke kinoea maoli), ke kaʻina hana oʻo, ke kumu kūʻai haʻahaʻa, a me ka laulā o ka hoʻohana.Ua lilo ia i lua o ka resin kumu nui loa ma ka honua ma hope o ka resin polyethylene.ʻO 29% o ka nui o ka hoʻohana resin synthetic o ka honua.He mea maʻalahi ka polyvinyl chloride a hiki ke hana ʻia e ka hoʻoheheʻe ʻana, laminating, injection molding, extrusion, calendering, blow molding, etc. e like me nā huahana plastik paʻakikī e like me nā pā, nā puka a me nā puka makani, nā paipu a me nā kiwi.
