Tlhahlobo ea thepa e tala ea marako a mabeli a HDPE
Tlhahlobo ea thepa e tala ea HDPE marako a mabeli a marako,
HDPE resin bakeng sa melumo e habeli ea lebota, mokhoa oa ho khetha resin ea HDPE bakeng sa marako a mabeli a marako,
Litlhokahalo tse akaretsang tsa thepa ea polyethylene (PE) li kenyelletsa sekhahla sa phallo ea ho qhibiliha (MFR), letsoalo, flexure elastic modulus le oxidation induction time (OIT), matla a ts'usumetso, joalo-joalo. Lintho tsa tlhahlobo li boetse li kenyelletsa matla a thata, bolelele nakong ea khefu, molora. , li-volatile le nako e 'ngoe ea ho kenya oxidation e lekanya nako ea tšenyo ea oxidation.Bakeng sa melumo e hlokang lilemo tse 50 tsa ts'ebeliso, ho laola nako ea tlhahiso ea oxidation ea lisebelisoa tse tala ke senotlolo sa ho netefatsa bophelo ba ts'ebeletso ea lilemo tse 50.Ho boletsoe ka ho hlaka ho GB/T19472.1-2004 hore nako ea ho kenya oxidation ea lihlahisoa tse tala e lokela ho ba ≥20min(200℃).
The elastic modulus ea HDPE resin e na le tšusumetso e kholo ho satalla ha selikalikoe.Lisebelisoa tse nang le modulus e phahameng ea elastic li ka ntlafatsa ho satalla ha lihlahisoa, empa hape li boloka lisebelisoa tse tala le ho fokotsa litšenyehelo tlas'a motheo oa ho netefatsa ho satalla ha selikalikoe.Kahoo tlhahisong ea HDPE e nang le marako a mabeli a marako, thepa e tala e sebelisoang e lokela ho ba le modulus e phahameng ea elasticity.Boholo ba sekhahla sa ho phalla ha metsi se bonahatsa boholo ba boima ba molek'hule.Ka kakaretso, thepa e nang le sekhahla sa phallo e phahameng ea ho qhibiliha e thusa ho sebetsa le ho theha, 'me e ka ntlafatsa katleho ea tlhahiso.Leha ho le joalo, e ke ke ea e-ba kholo haholo, e nang le tšusumetso e kholo ho satalla ha selikalikoe.Ka nako e ts'oanang, e tlameha ho ba le sekhahla se phahameng le ts'ebetso e ntle ea ts'ebetso le ho ikamahanya le maemo a lisebelisoa.
Boemo ba pipe ea HDPE bo na le kabo e pharaletseng kapa ea bimodal ea boima ba limolek'hule.E na le khanyetso e matla ea creep le botsitso bo botle ba ho tiea le ho tiea.E tšoarella haholo 'me e na le sag e tlase ha e sebetsoa.Liphaephe tse hlahisoang ho sebelisoa resin ena li na le matla a matle, ho tiea le ho hanyetsa tšusumetso le thepa e ntle ea SCG le RCP..
Resin e lokela ho bolokoa sebakeng sa polokelo se omeletseng, se omeletseng le hole le mollo le khanya ea letsatsi.Ha ea lokela ho bokelloa sebakeng se bulehileng.Nakong ea lipalangoang, thepa ha ea lokela ho pepesetsoa letsatsi le matla kapa pula 'me ha ea lokela ho tsamaisoa hammoho le lehlabathe, mobu, litšepe, mashala kapa khalase.Lipalangoang hammoho le lintho tse chefo, tse senyang le tse tukang li thibetsoe ka thata.
Kopo
Boemo ba liphaephe tsa HDPE bo ka sebelisoa ho hlahisa liphaephe tsa khatello, tse kang liphaephe tsa metsi tse hatelitsoeng, liphaephe tsa khase ea mafura le liphaephe tse ling tsa indasteri.E ka boela ea sebelisoa bakeng sa ho etsa liphaephe tse se nang khatello tse kang lipeipi tse nang le mabota a mabeli, lipeipi tse pota-potileng lebota, lipeipi tsa silicon-core, lipeipi tsa nosetso tsa temo le lipeipi tse kopantsoeng tsa aluminiumplastics.Ho feta moo, ka extrusion e sebetsang (silane cross-linking), e ka sebelisoa bakeng sa ho hlahisa liphaephe tsa polyethylene (PEX) tsa crosslinked polyethylene (PEX) bakeng sa ho fana ka metsi a batang le a chesang.
