Screw barrel bakeng sa filimi ea Blowing PP/PE/LDPE/HDPE
Screw Design: The screw for blown film extrusion hangata e entsoe joalo ka "grooved feed" screw. E na le lifofane tse tebileng le li-grooves ka bolelele ba eona ho nolofatsa ho qhibiliha ha resin, ho tsoakana le ho tsamaisa. Botebo le bophahamo ba sefofane bo ka fapana ho latela thepa e itseng e sebetsoang.
Barrier Mixing Section: Likurufu tsa filimi tse bululetsoeng hangata li na le karolo e thibelang ho kopanya haufi le pheletso ea screw. Karolo ena e thusa ho ntlafatsa ho kopanya ha polymer, ho netefatsa ho qhibiliha ho tsitsitseng le ho ajoa ha li-additives.
High Compression Ratio: Hangata screw e na le tekanyo e phahameng ea compression ho ntlafatsa homogeneity e qhibilihisang le ho fana ka viscosity e tšoanang. Sena ke sa bohlokoa bakeng sa ho fumana botsitso bo botle ba bubble le boleng ba filimi.
Kaho ea Moqomo: Moqomo hangata o entsoe ka tšepe ea boleng bo holimo e nang le kalafo e nepahetseng ea mocheso bakeng sa ho hanyetsa le ho tšoarella ha nako e telele. Li-barrel tsa nitriding kapa tsa bimetallic li ka boela tsa sebelisoa ho matlafatsa khanyetso ea ho apara bakeng sa bophelo bo atolositsoeng ba tšebeletso.
Sistimi ea ho Pholisa: Libarele tsa Screw bakeng sa extrusion ea filimi e fefotsoeng hangata li na le sistimi e pholileng ho laola mocheso le ho thibela ho chesa haholo nakong ea ts'ebetso ea extrusion.
Likarolo tsa Boikhethelo: Ho ipapisitsoe le litlhoko tse ikhethileng, likarolo tse ling tse kang "mellt pressure transducer" kapa "melt" sensor ea mocheso" li ka kenyelletsoa ka har'a "screw barrel" ho fana ka bokhoni ba ho lekola le ho laola.
Ho bohlokoa ho buisana le moetsi kapa morekisi ea tsebahalang oa screw barrel ho netefatsa hore o fumana moralo o nepahetseng oa sekoti bakeng sa ts'ebeliso ea hau ea filimi ea PP/PE/LDPE/HDPE. Ba ka fana ka likeletso tsa litsebi ho latela litlhoko tsa hau tse ikhethileng tsa tlhahiso, thepa ea thepa, le litlhoko tse lebelletsoeng tsa tlhahiso.
