Ko te hanganga kirihou PVC te nuinga o te titoPVC kapia me te taapiris, ko nga taapiri kia rite ki te mahi ka wehewehea ki: te whakapumau wera, te whakahinuhinu, te whakarereke tukatuka, te whakarereketanga o te paanga, te whakakii, te kaihoko tawhito, te tae me etahi atu.I mua i te hoahoa hangahanga PVC, me maarama taatau ki nga ahuatanga o te kapia PVC me nga momo taapiri.

Nga rauemi mata me nga taapiri

PVC kapia

Ko te whakaputanga o te kapia he polyvinyl chloride resin (PVC), ko te PVC he mea hanga mai i te vinyl chloride monomer polymerization polymer, ko te putanga tuarua ki te PE, ko te tuarua.

Ka taea te wehea te kapia PVC ki te momo wewete (XS) me te momo kiki (ⅺ) na te rerekee o te whakamararatanga o te polymerization.He 0.1-0.2mm te rahi o te matūriki, he kohikohiko te mata, he maiengi, he miro poroporo, he ngawari ki te ngongo i te plasticizer, te rahi o te matūriki kiato kei raro iho i te 0.1mm, he ture mata, he totoka, he ahua teepu tepu, kaore i te ngawari ki te whakauru i te plasticizer, te whakamahi o naianei. o momo wewete ake.

Ka taea te wehea te PVC ki te karaehe noa (PVC paitini) me te tohu hauora '(PVC kore-paitini).Ko nga whakaritenga tohu hauora mo te ihirangi vinyl chloride (VC) kei raro iho i te LOXL0-6, ka taea te whakamahi ki te kai me te rongoa.He rereke te tukanga waihanga, ka taea te wehea te PVC ki te PVC whakatārewatanga me te PVC whakaehunga.E ai ki te paerewa motu GB/T5761-93 "tikanga whakatārewatanga whānui polyvinyl pūhaumāota kapia inspection paerewa", te tikanga whakatārewa PVC kua wehea ki PVC-SGL ki PVC-SG8JK resin, te iti te tau, te nui te tohu o te polymerization, te nui te taimaha ngota, te teitei te kaha, engari te uaua ake te rere rewa, he uaua hoki te tukatuka.Kōwhiringa motuhake, mahi hua ngohengohe, te whakamahi whānui o PVC-SGL, PVC-SG2, PVC-SG3 momo, Me ki te tāpiri i te maha nui o plasticizers.Hei tauira, PVC kiriata whakamahi SG-2 resin, tāpiri 50 ki te 80 wahi o plasticizer.A, i te wa e tukatuka ana i nga hua pakeke, kaua e taapiri, e taapiri ranei i te plasticizer i roto i te iti rawa te nui, whakamahia te PVC-SG4, VC-SG5, PVC-SG6, PVC-SG7, PVC-SG8 na.Pērā i te putorino PVC mārō e whakamahi ana i te kāpia SG-4, ngā kōtaha kirihou kuaha me te matapihi mā te whakamahi i te kapia SG-5, te pepa mārō mā te whakamahi i te kapia SG-6, ngā pūkete pahuka i te whakamahi i te kapia SG-7, SG-8.Ka whakamahia te whakapiri PVC whakaehunga mo te hiako horihori, pepapātū me te hiako papa me nga hua kirihou toua.Ko etahi o nga kaihanga kapia PVC o te kapia PVC e ai ki te tohu polymerization (ko te tohu polymerization ko te maha o nga mekameka wae, ko te tohu polymerization kua whakareatia e te taumaha ngota o te mekameka he rite ki te taumaha ngota o te polymer) te whakarōpūtanga, penei i te Shandong Qilu petrochemical tipu whanui. hanga o PVC resin, hua wheketere mo SK-700;SK – 800;SK – 1000;SK – 1100;SK - 1200, me etahi atu. Ko te tohu o te polymerization o te SG-5 resin he 1000 - 1100. Ko nga ahuatanga o te tinana me te matū o te PVC resin ka kite i te tuawha.

Ko te paura PVC he paura ma me te kiato o 1.35 — 1.45 g/cm3 me te kiato kitea o 0.4-0.5 g/cm3.Tirotirohia te rahi o te ihirangi plasticizer ka taea te ngawari, nga hua pakeke, te ihirangi plasticizer whānui 0-5 he hua maro, 5-25 he hua ahua-pakeke, neke atu i te 25 he hua ngohengohe.

Ko te PVC te ahua o te amorphous, polymer polar, te whakamahana o te pāmahana me te rewa te pāmahana he tiketike, me te PVC parakore i roto i te 160-210 ~ C te tukatuka plasticizing, na te hononga polar i waenga i nga macromolecules kia whakaatu te PVC i te mahi pakeke me te pakarukaru.Ano, PVC rāpoi ngota kei roto rōpū māota, ka tae te pāmahana 120 ~ C, ka timata PVC parakore ki te tango HCl tauhohenga, ka arahi ki te waiariki degradation o PVC.Na reira, me whakauru nga momo taapiri katoa i roto i te tukatuka o te whakarereke PVC me te whakarereketanga o te paanga, kia taea ai te tukatuka hei hua whai hua.

Ko te PVC resin te nuinga e whakamahia ana mo te hanga i nga momo momo kiriata angiangi (penei i te kiriata tuhi i ia ra, i te kiriata kapi ahumahi, i te kiriata kati kōtuhi ahuwhenua, i te kiriata wera wera, me etahi atu), nga momo pereti, pepa, te pepa ka taea te whakamahi mo hua opupu), momo paipa katoa, penei i te paitini kore i runga i te paipa miro paipa, te ngongo maramara, me etahi atu), nga momo momo mea motuhake, penei i te kuaha, te matapihi, te pereti whakapaipai, te pounamu pupuhi (mo nga whakapaipai me te inu), Cable, momo momo hua werohia me te hiako horihori, hiako papa, taonga taakaro kirihou, aha atu.

Ko Zibo Junhai Chemical te angent tuatahi o Sinopec Qilu, te tohu PVC matua e whai ake nei.
