PVC resin
PVC yepurasitiki profil kugadzirwa kweresin ndeye polyvinyl chloride resin (PVC), PVC yakagadzirwa nevinyl chloride monomer polymerization polymer, inobuda yechipiri kune PE, ichiisa yechipiri.
PVC resin inogona kukamurwa kuita yakasununguka mhando (XS) uye yakasimba mhando (ⅺ) nekuda kweakasiyana anoparadzira mupolymerization.Loose particle size is 0.1-0.2mm, iyo yepamusoro haina kurongeka, porous, donje bhora, nyore kutora plasticizer, compact particle size iri pazasi 0.1mm, mitemo yepasi, yakasimba, tafura tennis chimiro, hazvisi nyore kutora plasticizer, kushandiswa kwazvino. zve loose type more.
PVC inogona kukamurwa kuita yakajairika giredhi (chepfu PVC) uye hutano giredhi '(isina chepfu PVC).Zvinodiwa zvegiredhi rehutano zvevinyl chloride (VC) zviri pasi peLOXL0-6, zvinogona kushandiswa muchikafu nemushonga.Synthetic maitiro akasiyana, PVC inogona kukamurwa kuva kuturika PVC uye emulsion PVC.Zvinoenderana neiyo yenyika standard GB/T5761-93 "suspension nzira general polyvinyl chloride resin inspection standard", nzira yekumisa PVC yakakamurwa kuita PVC-SGL kuenda kuPVC-SG8JK resin, iyo idiki nhamba, iyo yakakura dhigirii yepolymerization, iyo yakakura. iyo molecular uremu, iyo yakakwirira simba, asi zvakanyanya kuoma kunyunguduka kuyerera, kugadzirisa zvakare kwakanyanya kuoma.Sarudzo chaiyo, ita zvigadzirwa zvakapfava, iyo yakajairika kushandiswa kwePVC-SGL, PVC-SG2, PVC-SG3 mhando, inoda kuwedzera huwandu hukuru hwepurasitiki.Somuenzaniso, PVC firimu kushandisa SG-2 resin, achiwedzera 50 kusvika 80 zvikamu plasticizer.Uye paunenge uchigadzira zvigadzirwa zvakaoma, usawedzera kana kuwedzera plasticizer mune shoma shoma kazhinji, shandisa PVC-SG4, VC-SG5, PVC-SG6, PVC-SG7, PVC-SG8 saka.Zvakadai sePVC yakaoma pombi uchishandisa SG-4 resin, epurasitiki musuo uye hwindo profiles uchishandisa SG-5 resin, yakaoma läpinäkyvä pepa uchishandisa SG-6 resin, yakaoma furo Profiles vachishandisa SG-7, SG-8 resin.Uye emulsion PVC paste inonyanya kushandiswa kugadzira matehwe, Wallpaper uye pasi dehwe uye dip epurasitiki zvigadzirwa.Vamwe vagadziri vePVC resin vanogadzira PVC resin zvinoenderana nedhigirii repolymerization (dhigirii repolymerization ndiyo nhamba yeyuniti cheni, dhigirii repolymerization rakapetwa nehuremu hwemamorekuru echeni yakaenzana nehuremu hwepolymer) kupatsanurwa, senge Shandong Qilu petrochemical general plant. kugadzirwa kwePVC resin, zvigadzirwa zvefekitari zveSK-700;SK - 800;SK - 1000;SK – 1100;SK - 1200, etc. Dhigirii inopindirana yepolymerization yeSG-5 resin ndeye 1000 - 1100. Izvo zvepanyama uye zvemakemikari ePVC resin ona yechina.
PVC poda ipfu chena ine density ye1.35 - 1.45 g/cm3 uye inooneka density ye0.4-0.5 g/cm3.Ongorora saizi yemukati meplasticizer inogona kuve yakapfava, yakaoma zvigadzirwa, general plasticizer yemukati 0-5 zvigadzirwa zvakaoma, 5-25 isemi-yakaoma zvigadzirwa, zvinopfuura makumi maviri neshanu zvigadzirwa zvakapfava.
PVC imhando yeamorphous, polar polymer, kupfava tembiricha uye tembiricha yekunyunguduka yakakwira, yakachena PVC kazhinji inofanira kunge iri mu160-210 ~C plasticizing processing, nekuda kweiyo polar bond pakati pemacromolecules kuitira kuti PVC iratidze kuomarara uye kuita brittle kuita.Uyezve, maPVC mamorekuru ane chlorine mapoka, kana tembiricha yasvika 120 ~ C, yakachena PVC inotanga kubvisa HCl reaction, inotungamira mukupisa kwekupisa kwePVC.Naizvozvo, marudzi ese ezvekuwedzera anofanirwa kuwedzerwa mukugadziriswa kwePVC gadziriso uye gadziriso yekuchinja, kuitira kuti igadziriswe kuita chigadzirwa chinobatsira.
PVC resin inonyanya kushandiswa kugadzira marudzi akasiyana-siyana efirimu rakatetepa (senge zuva nezuva kudhinda firimu, maindasitiri ekurongedza firimu, yekurima greenhouse firimu, kupisa kupisa firimu, nezvimwewo), marudzi ese endiro, pepa, pepa rinogona kushandiswa. blister zvigadzirwa), marudzi ese emapombi, akadai seasina chepfu papombi inopinza pombi, pombi inoonekera, nezvimwewo), marudzi ese emhando dzakashongedzerwa, senge gonhi, hwindo, ndiro yekushongedza, bhodhoro rekuputika (kwezvizoro uye zvinwiwa), Cable, marudzi ese ezvigadzirwa zvejekiseni nematehwe ekugadzira, dehwe repasi, matoyi epurasitiki, nezvimwe.
Zibo Junhai Chemical ndiyo yekutanga mumiriri weSinopec Qilu, iyo huru PVC mhando inotevera.
