China PVC zita rechiratidzo rinowanzo shandiswa polymerization dhigirii kana modhi rondedzero.Semuenzaniso, mhando nomwe dzePVC (brand S-800, SG-7) kana sere rudzi PVC (brand S-700, SG-8) ine hutano hwakanaka hucharatidzwa zvakasiyana nevagadziri vakasiyana.Mazhinji acho akanyorwa neSG uye digit imwe chete kumiririra PVC modhi.Huwandu hwemazana nezviuru mamaki hunomiririra dhigirii repolymerization (nhamba imwechete inomiririra chigadzirwa chimwe chete, seQingdao Haijing HS1000, Shanghai chlor-alkali WS1000,Qilu Petrochemical S1000ese anomiririra mashanu-mhando PVC).
MUFANANIDZO UNOTI MUNHU WEMUMBA UNOSHANDISA ZVINHU ZVINOSHANDISA ZVINHU 7, 8, ZVINO SHANDISA KAZHINJI KUTI QILU PETROCHEMICAL, Shanghai CHLOR-ALKALI, CANG HUA, Qingdao HAI JING, DAGU HUA'S PRODUCT.
Vamwe vatsva uye vanofarira vanobatana vangabvunza kuti nei vagadziri vemapepa vachifarira kushandisa Type 7 uye mhando 8 pane yerudzi rwe5. Hapana imwe, asi nomwe, sere mhando PVC polymerization degree yakaderera, iri nyore kugadzirisa.Kwete pepa chete, PVC pombi fittings, PVC mavharuvhu akakodzerawo kushandiswa.
Mafekitari epombi anowanzo shandisa rudzi rwe 5. Chikamu chikuru che calcium carbonate chakawedzerwawo kuderedza mari, iyo isingafaniri kutsanangurwa pano.
Mumakore iwayo anotyisa, PVC munyika yedu yakakamurwa kuva marudzi masere, anoti rudzi 1 kusvika ku8. Hama sere dzakaedzwa (dzakaparadzwa) nomusika, uye ina bedzi dzakasara:
Type 3(polymerization degree 1300, inonyanya kushandiswa kugadzira waya uye tambo, calendering firimu), mhando 5 (polymerization dhigirii 1000, rinonyanya kushandiswa kune profiles, pombi), uye mhando yechisere.
Mainstream PVC kugadzira uchishandisa kumiswa nzira, pakusarudza kwakasiyana kumiswa dispersant, inogona kuwanikwa particle chimiro uye morphology yemhando mbiri dzakasiyana resin.
