Lebitso la China PVC hangata le sebelisoa tekanyo ea polymerization kapa tlhaloso ea mohlala.Ka mohlala, mefuta e supileng ea PVC (brand S-800, SG-7) kapa mofuta o robeli oa PVC (brand S-700, SG-8) e nang le boleng bo botle e tla tšoauoa ka tsela e fapaneng ke bahlahisi ba fapaneng.Boholo ba tsona li tšoailoe ka SG le nomoro e le 'ngoe ho emela mefuta ea PVC.Palo ea matšoao a makholo le likete a emela tekanyo ea polymerization (palo e tšoanang e emela sehlahisoa se tšoanang, joalo ka Qingdao Haijing HS1000, Shanghai chlor-alkali WS1000,Qilu Petrochemical S1000kaofela li emela PVC ea mefuta e mehlano).

PAPATSO HORE LEARA LA LAPENG LE SEBELISA SEBELISA HO EKETSEHILENG, MEFUTA E 8, E SEBELE EFE KA TLWAELEHILENG KE QILU PETROCHEMICAL, Shanghai CHLOR-ALKALI, CANG HUA, Qingdao HAI JING, SEHLAHISO SA DAGU HUA.

Balekane ba bang ba bacha le ba thahasellang ba ka 'na ba botsa hore na ke hobane'ng ha baetsi ba maqephe ba khetha ho sebelisa Mofuta oa 7 le oa mofuta oa 8 ho e-na le mofuta oa 5. Ha ho e 'ngoe, empa tekanyo ea PVC polymerization ea mefuta e supileng, e robeli e tlaase, e bonolo ho e sebetsa.Hase feela lakane, liphaephe tsa PVC, li-valve tsa PVC le tsona li loketse ho sebelisoa.

Hangata lifeme tsa lipeipi li sebelisa mofuta oa 5. Karolo e phahameng ea calcium carbonate e ile ea boela ea eketsoa ho fokotsa litšenyehelo, tse sa lokelang ho hlalosoa mona.

Lilemong tseo tse mahlonoko, PVC naheng ea habo rōna e ne e arotsoe ka mefuta e robeli, e leng mofuta oa 1 ho ea ho oa 8. Barab’abo rōna ba robeli ba ile ba lekoa (ba senngoa) ke ’maraka, ’me ho ile ha sala ba bane feela:

Mofuta oa 3(Polymerization degree 1300, haholo-holo e sebelisetsoang ho etsa terata le thapo, filimi ea calendering), mofuta oa 5 (polymerization degree 1000, e sebelisoang haholo bakeng sa profiles, liphaephe), le mofuta oa 7 robeli.

Tlhahiso e kholo ea PVC e sebelisang mokhoa oa ho emisoa, ha ho khethoa li-dipersant tse fapaneng tsa ho emisoa, ho ka fumanoa sebopeho sa likaroloana le morphology ea mefuta e 'meli e fapaneng ea resin.
