Ibisigarira byo gukora imyirondoro ya PVC ni polyvinyl chloride resin (PVC).Polyvinyl chloride ni polymer ikozwe muri vinyl chloride monomer.

Ibisigarira bya PVC birashobora gushyirwa mubwoko bubiri, ubwoko bworoshye (XS) nubwoko bworoshye (XJ), bitewe numukozi ukwirakwiza muri polymerisation.Ingano yubunini irekuye ni 0.1-0.2mm, hejuru ntisanzwe, yuzuye, ipamba isa, byoroshye kwinjiza plastiseri, ubunini buke buri munsi ya 0.1mm, ubuso nibisanzwe, bikomeye, tennis ya kumeza, biragoye kwinjiza plastike, At ihari, Ubwoko Bwinshi Bwakoreshejwe.

PVC irashobora kugabanywa mubyiciro bisanzwe (uburozi bwa PVC) nicyiciro cyisuku (PVC idafite uburozi).Urwego rwisuku rusaba vinyl chloride (VC) iri munsi ya 10 × 10-6, ishobora gukoreshwa mubiribwa nubuvuzi.Uburyo butandukanye bwogukora, PVC irashobora kugabanwa muburyo bwo guhagarika PVC na emulsiyo PVC.Ukurikije ibipimo ngenderwaho by’igihugu GB / T5761-93 “Igipimo cy’ubugenzuzi rusange bwa polyvinyl chloride resin igamije uburyo bwo guhagarika”, uburyo bwo guhagarika PVC bugabanijwemo PVC-SG1 kugeza PVC-SG8 ubwoko umunani bw’ibisigarira, aho umubare muto ari muto, nini urwego rwa polymerisiyasi, uburemere bwa molekuline nabwo Nimbaraga nini, niko gutemba gutemba, kandi bigoye kuyitunganya.

Iyo uhisemo ibicuruzwa byoroshye, PVC-SG1, PVC-SG2, na PVC-SG3 bikoreshwa muri rusange, kandi hagomba kongerwaho umubare munini wa plastike.Kurugero, firime ya polyvinyl chloride ikozwe muri SG-2, hanyuma hiyongeraho ibice 50 kugeza kuri 80 bya plastike.Iyo gutunganya ibicuruzwa bikomeye, plasitike ntishobora kwongerwaho cyangwa kongerwaho muke, bityo PVC-SG4, PVC-SG5, PVC-SG6, PVC-SG7, na PVC-SG8.

Kurugero, resin ya SG-4 ikoreshwa kumuyoboro ukomeye wa PVC, resin ya SG-5 ikoreshwa kumuryango wa plastiki no mwirondoro ryidirishya, resin ya SG-6 ikoreshwa muri firime ikorera mu mucyo, naho SG-7 na SG-8 zikoreshwa kuri umwirondoro ukomeye.Uburyo bwa emulsion paste ya PVC ikoreshwa cyane cyane muruhu rwubukorikori, wallpaper, uruhu rwo hasi nibicuruzwa bya plastiki.Bamwe mu bakora inganda za PVC bohereza PVC resin ukurikije urugero rwa polymerisiyasi (urwego rwa polymerisiyasi ni umubare w’ibice bihuza, urugero rwa polymerisiyasi rwikubye nuburemere bwa molekile yumunyururu bingana nuburemere bwa molekile ya polymer), nka PVC resin yakozwe na Shandong Qilu Petrochemical Plant, ibicuruzwa byuruganda Ni S-700;S-800;S-1000;S-1100;S-1200.

SG-5 resin ifite impamyabumenyi ya polymerisation kuva 1.000 kugeza 1100.Ifu ya PVC ni ifu yera ifite ubucucike buri hagati ya 1.35 na 1.45 g / cm3 nubucucike bugaragara bwa 0.4 kugeza 0.5 g / cm3.Dufata ibikubiye muri plasitike mubicuruzwa bya PVC nkibicuruzwa byoroshye kandi bikomeye.Mubisanzwe, ibice bya plastike ni ibice 0 ~ 5 kubicuruzwa bikomeye, ibice 5 ~ 25 kubicuruzwa bitoroshye, nibice birenga 25 kubicuruzwa byoroshye.

Zibo Junhai Chemical niyo itanga isoko ya Pvc Resin.Turashobora gutanga PVC Resin S3, PVC Resin SG5, PVC Resin SG8, ​​PVC Resin S700, PVC Resin S1000, PVC Resin S1300 ext.Kandi ikomoka mubakora inganda zikomeye mubushinwa, nka Erdos PVC Resin, Sinopec PVC Resin, Beiyuan PVC Resin, Xinfa PVC Resin, Zhong tai PVC Resin, Tianye PVC Resin.ext.

Polyvinyl chloride ifite ibintu byihariye biranga ibikoresho fatizo byinshi (amavuta, hekeste, kokiya, umunyu na gaze karemano), uburyo bwo gukora bukuze, igiciro gito, hamwe nuburyo bukoreshwa.Bibaye icya kabiri kinini muri rusange-intego ya resin kwisi nyuma ya polyethylene.29% byisi yose ikoreshwa muri resinike.Choride ya polyvinyl iroroshye kuyitunganya kandi irashobora gutunganywa no kubumba, kumurika, gutera inshinge, kuyikuramo, kalendari, guhumeka, n'ibindi. nkibicuruzwa bikomeye bya plastike nkibisahani, inzugi nidirishya, imiyoboro na valve.
