Lisebelisoa tse tala bakeng sa ho hlahisa liphaephe tsa PVC
Lisebelisoa tse tala bakeng sa ho hlahisa liphaephe tsa PVC,
Resin ea PVC, PVC ho hlahisa phala,
S-1000 polyvinyl chloride resin e hlahisoa ka mokhoa oa ho emisa polymerization o sebelisa vinyl chloride monomer joalo ka thepa e tala.Ke mofuta oa motsoako oa polymer o nang le letsoalo le lekanyelitsoeng la 1.35 ~ 1.40.Sebaka sa eona sa ho qhibiliha se ka bang 70 ~ 85 ℃.Botsitso bo fokolang ba mocheso le ho hanyetsa khanya, ho feta 100 ℃ kapa nako e telele tlas'a letsatsi hydrogen chloride e qala ho bola, tlhahiso ea polasetiki e hloka ho eketsa li-stabilizers.Sehlahisoa se lokela ho bolokoa sebakeng se omeletseng le se nang le moea o motlakase.Ho ea ka palo ea polasetiki, bonolo ba polasetiki bo ka fetoloa, 'me resin ea peista e ka fumanoa ka emulsion polymerization.
Grade S-1000 e ka sebelisoa ho hlahisa filimi e bonolo, lakane, letlalo le entsoeng ke motho, liphaephe, bar e bōpehileng, bellow, pipe ea tšireletso ea cable, filimi ea ho paka, sole le thepa e 'ngoe e bonolo.

Liphaephe tsa PVC li entsoe ka extrusion ea thepa e tala ea PVC, 'me ka kakaretso li latela mehato e tšoanang ea ts'ebetso e tloaelehileng ea liphaephe:
1.Ho fepa phofo e tala e bitsoang resin le filler ho PVC twin screw extruder;
2. Ho qhibiliha le ho futhumatsa libakeng tse ngata tsa extruder;
3. Ho ntša ka har'a thae ho bopeha ho ba phala;
4.Ho pholile ha pipe e bōpehileng (ka ho fafatsa metsi ka pipe);le
5. Ho khaola liphaephe tsa PVC ka bolelele bo lakatsehang.
Lisebelisoa tse tala bakeng sa ho hlahisa liphaephe tsa PVC ke resin le filler (haholo-holo calcium carbonate, kapa e tsejoang ka hore ke majoe).Motsoako o tloaelehileng ke 1 kilogram (kg) ea resin le 1 kilogram ea filler.Hangata mekhoa ea tlhahiso e etsoa ka mokhoa o ikemetseng, 'me basebetsi ba fepa thepa e tala qalong ea ts'ebetso, ba lekola mocheso nakong ea ts'ebetso le ho hlahloba sehlahisoa sa ho qetela bakeng sa liphoso tse totobetseng pele ba paka le ho romela bareki.Basebetsi bohle ba kwetlisitswe mme ba kgona ho etsa mesebetsi ena kaofela ka bokgabane.Ntho e ka sehloohong ea ho etsa liphaephe tsa PVC ke phofo e bitsoang PVC resin.
