Single Screw Extruders: The Versatile Workhorses
Single screw extruder ke mofuta o atileng haholo le o feto-fetohang oa mohala oa polasetiki oa extrusion. Li khetholloa ka sekoti se le seng se potolohang se fetisang le ho qhibilihisa thepa ea polasetiki. Ho ba bonolo ha bona le ho baballa litšenyehelo ho li etsa hore li tšoanelehe bakeng sa lits'ebetso tse fapaneng, ho kenyelletsa:
Pipe le Tubing Extrusion: Li-extruder tsa "screw" tse le 'ngoe li sebelisoa haholo ho hlahisa liphaephe le li-tubing bakeng sa lisebelisoa tse fapaneng, ho kenyeletsa lipeipi tsa metsi, nosetso le liphaephe tsa motlakase.
Profaele Extrusion: Li-extruder tsena li ipabola ka ho theha li-profile, joalo ka liforeimi tsa lifensetere, liforeimi tsa mamati le thepa ea moaho.
Filimi ea Extrusion: Li-scruders tse le 'ngoe li thusa ho hlahisa lifilimi tse tšesaane tsa polasetiki bakeng sa ho paka, temo le lisebelisoa tsa indasteri.
Twin Screw Extruders: Ts'ebetso e Ntlafetseng bakeng sa Likopo tse Batlang
Li-extruder tse peli tsa li-screw li phahamisa bokhoni ba polasetiki ea extrusion, li fana ka motsoako o phahameng, ho qhibiliha le ho hasana ha thepa ea polasetiki. Li-screw tsa bona tse peli tse hokahaneng li sebetsa ka tandem, li fana ka ts'ebetso e ntlafalitsoeng bakeng sa lits'ebetso tse hlokang, ho kenyelletsa:
Colour Masterbatch Extrusion: Twin screw extruder ke khetho e ratoang bakeng sa ho hlahisa li-masterbatches tsa boleng bo holimo, tse netefatsang kabo e sa fetoheng ea mebala le ho hasana.
Compounding Extrusion: Li-extruder tsena li ipabola ka ho kopanya, moo li-additives le li-filler li kenngoa ka har'a polasetiki e qhibilihang ho fihlela thepa e itseng.
Thermoplastic Elastomer (TPE) Extruder: Twin screw extruder e loketse hantle bakeng sa ho hlahisa li-TPE, tse kopanyang thepa ea rabara le polasetiki.
Co-Extrusion Lines: Ho theha Lihlahisoa tsa Multilayer tse nang le ts'ebetso e ntlafetseng
Li-co-extrusion line li nka polasetiki ea extrusion ho ea boemong bo latelang ka ho kopanya melapo e 'meli kapa ho feta ea polymer hore e be sehlahisoa se le seng. Sena se thusa ho theha lihlahisoa tsa multilayer tse nang le thepa e ntlafalitsoeng, joalo ka:
Lifilimi tsa Barriers: Mehala ea Co-extrusion e hlahisa lifilimi tse thibelang oksijene le ho hanyetsa mongobo, tse loketseng ho paka lijo le lisebelisoa tsa meriana.
Multifunctional Profiles: Mehala ena e theha liprofaele tse nang le thepa e fapaneng mokatong o mong le o mong, e sebetsanang le lits'ebetso tse hlokang litšobotsi tse itseng.
Medical Tubing: Co-extrusion line li hlahisa li-tubing tsa bongaka tse nang le biocompatibility e phahameng le matla bakeng sa lits'ebetso tse fapaneng tsa bongaka.
Ho Khetha Mohala o Nepahetseng oa Plastic Extrusion bakeng sa Litlhoko tsa Hao
Khetho ea mohala o nepahetseng oa polasetiki oa extrusion o ipapisitse le lintlha tse 'maloa, ho kenyelletsa:
Mofuta oa Sehlahisoa: Sebopeho le thepa e lakatsehang e laola mofuta oa extruder e hlokahalang.
Litlhoko tsa Boitsebiso: Ho lumellana ha extruder le thepa e khethehileng ea polasetiki ho bohlokoa.
Bophahamo ba Tlhahiso: Bokhoni ba tlhahiso ea extruder bo lokela ho ikamahanya le tlhoko ea tlhahiso e lebelletsoeng.
Litlhokomelo tsa Lichelete: Litsenyehelo tsa extruder le lisebelisoa tse amanang le eona li tlameha ho lumellana le mathata a lichelete.
Qiangshengplas: Molekane oa Hao ka Bokhabane ba Plastic Extrusion
Qiangshengplas, re ikemiselitse ho fa bareki ba rona melapo ea boleng bo holimo ea polasetiki e fihlelang litlhoko tsa bona tse ikhethileng. Sehlopha sa rona se nang le boiphihlelo se ka u tataisa ts'ebetsong ea khetho le ho netefatsa hore u tsetela lisebelisoa tse nepahetseng bakeng sa katleho ea hau ea tlhahiso.
Ka boitseanape ba rona bo pharaletseng ba theknoloji ea extrusion ea polasetiki, re fana ka mefuta e felletseng ea sekoti se le seng, sekoti se le seng, le likhoele tsa co-extrusion, tse sebetsanang le lits'ebetso tse fapaneng. Boitlamo ba rona ba boiqapelo le khotsofalo ea bareki bo re entse balekane ba tšepahalang ba likhoebo lefatšeng ka bophara.
Ikopanye le rona kajeno ho hlahloba hore na mela ea rona ea polasetiki ea extrusion e ka fetola bokhoni ba hau ba ho etsa joang le ho phahamisetsa lihlahisoa tsa hau boemong bo bong.
