Hoʻohana pinepine ʻia ka inoa inoa PVC o Kina i ka polymerization degere a i ʻole ka hōʻike kumu hoʻohālike.No ka laʻana, ʻehiku ʻano PVC (brand S-800, SG-7) a i ʻole ʻewalu ʻano PVC (brand S-700, SG-8) me ka maikaʻi maikaʻi e hōʻailona ʻokoʻa ʻia e nā mea hana like ʻole.Hōʻailona ʻia ka hapa nui o lākou me SG a me ka helu hoʻokahi e hōʻike i nā hiʻohiʻona PVC.ʻO ka helu o nā haneli a me nā kaukani hōʻailona e hōʻike ana i ka degere o ka polymerization (ʻo ka helu like e hōʻike ana i ka huahana like, e like me Qingdao Haijing HS1000, Shanghai chlor-alkali WS1000,Qilu Petrochemical S1000ʻO nā mea a pau e hōʻike ana i ka PVC ʻelima ʻano).
KA HOʻOPIʻI ANA I KA PALAPALA PALAPALA PALAPALA HOʻOPIʻI 7, 8 ANO AʻO, KA HOʻohana maʻamau ʻo QILU PETROCHEMICAL, Shanghai CHLOR-ALKALI, CANG HUA, Qingdao HAI JING, KA HUA A DAGU HUA.
E nīnau paha kekahi mau hoa hou a hoihoi i ke kumu e makemake ai ka poʻe hana pepa e hoʻohana i ka Type 7 a me ke ʻano 8 ma mua o ke ʻano 5. ʻAʻohe mea ʻē aʻe, akā ʻehiku, ʻewalu ʻano PVC polymerization degere haʻahaʻa, maʻalahi e hana.ʻAʻole wale ka pepa, nā paipu PVC paipu, nā kiwi PVC kūpono hoʻi no ka hoʻohana.
Hoʻohana maʻamau nā hale hana paipu i ke ʻano 5. Ua hoʻohui pū ʻia kahi hapa kiʻekiʻe o ka calcium carbonate e hōʻemi i nā kumukūʻai, ʻaʻole pono e wehewehe ʻia ma aneʻi.
I kēlā mau makahiki weliweli, ua māheleʻia ka PVC ma ko mākou'āina iʻewalu mauʻano,ʻo ia hoʻi keʻano 1 a hiki i ka 8. Ua ho'āʻoʻia nā kaikunāneʻewalu e ka mākeke, aʻehā wale nō i koe:
ʻAno 3(polymerization degere 1300, ka hapanui i hoʻohana 'ia no ka hana uea a me ka uwea, calendering kiʻiʻoniʻoni), type 5 (polymerization degere 1000, ka hapanui hoʻohana 'ia no profiles, paipu), a me type 7 ewalu.
ʻO ka hana nui o ka PVC me ka hoʻohana ʻana i ke ʻano hoʻokuʻu, ma ke koho ʻana i nā dispersant suspension ʻē aʻe, hiki ke loaʻa i ka ʻāpana ʻāpana a me ka morphology o nā ʻano resin ʻelua.
