Ke eng e lokelang ho lebisoa tlhokomelo ho ho bopa ha extrusion ea thepa ea chlorinated polyethylene?

Batho ba bangata ha ba tsebe polyethylene ea chlorinated, 'me joalokaha lebitso le bontša, batho ba bangata ba lokela ho bona feela hore ke lik'hemik'hale. E na le mokhoa o bitsoang extrusion molding, e ntseng e le ea bohlokoa haholo ts'ebetsong ea tlhahiso. Joale kajeno, re lokela ho ela hloko eng nakong ea ts'ebetso ea ho bopa extrusion ea sehlahisoa see? Mokelikeli oa polyvinyl chloride

1. Ka mokhoa oa lihlahisoa tse tala bakeng sa ho etsa liphaephe, tlhokomelo e lokela ho lefshoa ho khethoa ha li-stabilizers le lithuso tse ling tsa ho sebetsa, ka sepheo se seholo sa ho ntlafatsa ntlafatso ea ho qhibiliha ha metsi le ho matlafatsa botsitso ba mocheso oa lihlahisoa tse tala. Haeba ho hlokahala, lisebelisoa tsa foromo li ka tsoakoa pele, 'me lisampole tse nyane li ka nkuoa bakeng sa tlhahlobo. Haeba ho se na ntho e hlakileng ea ho fetoha ha mebala kapa ho qhibiliha ka har'a lebokose la phepelo la 230 ℃ bakeng sa lihora tse 2, ho bontša hore khetho ea lisebelisoa tse thusang e utloahala haholoanyane.

2. The extrusion ho bōpa mocheso oa thepa ea chlorinated polyvinyl chloride e phahame hanyenyane ho feta ea liphaephe tsa PVC. Empa hoa lokela ho hlokomeloa hore ho feto-fetoha ha mocheso oa mocheso ho ke ke ha feta ± 5 ℃.

3. Nakong ea tlhahiso ea liphaephe tsa CPVC, haeba ho e-na le khaello ea motlakase, ho se sebetse ha thepa, matšoao a ho senyeha ha thepa e qhibilihisang, kapa mosi o tsoang molomong oa hlobo, phepelo ea thepa ho moqomo oa mochine e lokela ho emisoa hang-hang. Resin ea PVC e lokela ho sebelisoa ho tlosa lisebelisoa tse qhibilihang tsa CPVC ho tloha moqomong oa mochini le hlobo, ebe mochini o lokela ho emisoa ho rarolla mathata.

4. Pele resin e kenngoa tlhahiso, e tlameha ho omisoa le ho tšoaroa ka lebokose la phepelo la 80 ℃ bakeng sa lihora tse 2-4. Haeba ho hlokahala, lisebelisoa tse tala tse tsoakiloeng ka lebelo le phahameng le tsona li lokela ho sefshoa ka sefe ea 40 mesh hang, ebe li kenngoa ka har'a extruder hopper bakeng sa tlhahiso.

5. Khase ea HCl e lokollotsoeng nakong ea ho senyeha ha CPVC e qhibiliha e kotsi ho bophelo bo botle ba batho, 'me tlhokomelo e lokela ho lefshoa ho moea o kenang sebokeng sa tlhahiso.

6. Moqomo oa mochini oa extrusion, screw, le lintho tse entsoeng ka ho qhibilihisoa tse phallang ka har'a hlobo ea ho bōpa e sebelisetsoang ho hlahisa resin ea CPVC e tlameha ho etsoa kalafo e khahlanong le kutu ho lelefatsa bophelo ba tšebeletso ea likarolo tsa lisebelisoa.

Ts'ebetsong ea 'nete ea tlhahiso, mokhoa oa ho bopa oa extrusion oa chlorinated polyvinyl chloride o ntse o le thata haholo. Ha e le hantle, ke habohlokoa ho khetha sehlahisoa se loketseng ha u se sebelisa maemong a itseng, 'me re lokela ho hlahloba ka hloko tekanyo ea sehlahisoa ho thusa ho sebelisoa ka katleho.
