E le moetapeleMoetsi oa Mochini oa Extrusion oa PVC Profile, Qiangshengplas e utloisisa ho rarahana ha mokhoa oa extrusion le mathata a ka hlahang. Sehloohong sena, re bua ka potso e itseng ea 'mali mabapi le litaba tse kopaneng nakong ea extrusion ea motsoako o nang le LDPE le lehlabathe. Ka ho sekaseka mathata le ho fana ka litharollo tse ling, re ikemiselitse ho u fa matla a ho ntlafatsa ts'ebetso ea hau ea tlhahiso le ho fihlela litholoana tse atlehileng.
Mathata a Babali:
'Mali o khethile mathata a mararo a mantlha nakong ea ts'ebetso ea bona ea extrusion:
Karohano ea Lehlabathe:Lehlabathe le arohana le LDPE ka lebaka la phapang ea boima ba 'mele, e bakang ho thibela le ho eketseha ha motlakase ho extruder.
Phallo le Khase:Motsoako o chesang (o ka bang 200 ° C) o bonts'a phallo e feteletseng le ho tsoa ha khase nakong ea ho hatella, e lebisang ho lutla ho tloha hlobo.
Phetoho ea Kamor'a Mold le ho Petsoha:Lithaele tse entsoeng li bonahala li phethahetse qalong empa li holofala 'me li petsoha ka mor'a nakoana, li beha sebopeho le botle ba tsona kotsing.
Ho Nahanisisa Bocha Mokhoa ona: Mekhoa e meng ea Tlhahiso
Tlhahiso ea mantlha e kenyelletsa ho nkela mohato oa extrusion sebaka ka mokhoa oa ho etsa pele. Mona ke karohano ea mokhoa o mong:
Tlhahiso ea Pele ho Foromo:Kopanya 'me u qhibilihe li-precursor ho liforomo tse nang le lisebelisoa tse lekaneng bakeng sa lihlahisoa tse' maloa tsa ho qetela. Sena se ka etsoa ka sejana se bonolo sa ho kopanya.
Ho Pholisa le ho Chaja Pele:Lumella li-pre-forms hore li pholile ka ho feletseng. Ebe u li khaola ka litefello tse nyane pele u sebelisa thipa e chesang ea terata kapa lehare le sehang.
Thekiso ea Mocheso o Tlase:Sebelisa mokhoa oa ho hatella ka mocheso o tlase ho hatella li-pre-charge libopeho tsa tsona tsa ho qetela tsa litene.
Melemo ea mokhoa ona:
E Felisa Mathata a Amanang le Lehlabathe:Ka ho hlahisa lehlabathe ka mor'a ho kopanya ha pele, o felisa bothata ba ho arohana ka har'a extruder le ho fokotsa ho apara lisebelisoa tsa ho itšeha le ho bōpa.
Taolo ea Phallo e Ntlafetseng:Lithempereichara tse tlase tsa ho bopa li fana ka taolo e betere holim'a phallo ea thepa, ho fokotsa ho lutla nakong ea ho hatella.
Ho Fokotsa Cracking:Lithempereichara tse tlaase le ho kopanya ho tšoanang ho thusa ho thibela ho senyeha ha hlobo le ho phunyeha ho bakoang ke ho fokotseha ho sa tšoaneng ha thepa e fapaneng.
Khothatso e tsoang ho Mekhoa e Thehiloeng:
Mould Molding ea Maqephe (SMC) Compression Molding:Mokhoa ona o sebelisoang haholo o sebelisa fiberglass filler sebakeng sa lehlabathe mme e fana ka ts'ebetso e ts'oanang ea ho theha likarolo tse kopaneng. Ho etsa lipatlisiso ka SMC ho ka fana ka leseli la bohlokoa bakeng sa mokhoa oa hau oa ho theha pele.
Hot Forging:Mokhoa ona o bonts'a katleho ea liforomo tsa pele ho ho bopa lisebelisoa tse chesang ka ho bopa ha compression.
Ho ntlafatsa li-Parameters tsa Compression Molding
Taolo ea Mocheso:Sebelisa Vicat Softening Temperature le Heat Deflection Temperature ea thepa ea hau ho fumana mocheso o nepahetseng oa sesebelisoa sa compression. Sena se netefatsa phallo e nepahetseng ea thepa le ho fokotsa ho phatloha.
Tonnage le Pre-Heating:Sebelisa lipalo ho latela boholo ba sebopeho sa pele le thepa ea thepa ho beha lithane tse loketseng tsa khatiso le mocheso o futhumatsang pele bakeng sa ho hatella ka katleho.
Likhetho tsa ho Pholisa Mold:Nahana ka lithulusi tse hatselitsoeng pele kapa lithempereichara tse batlang li le holimonyana ho feta hore li be thata haholo ha li hatelloa.
Lintlha tse ling bakeng sa Khokahanyo ea Lehlabathe:
Haeba ho kenyelletsa lehlabathe nakong ea sethala sa extrusion ho ntse ho hlokahala, hlahloba mokhoa oa "Sheet Molding Compound". Mona, polasetiki e fetisoa pele, e lateloa ke ts'ebetso ea lehlabathe le lera la ho qetela la polasetiki pele ho khatello. Mokhoa ona o khothalletsa kabo e ntle ea lehlabathe le ho fokotsa ho roala ha lisebelisoa.
Qetello
Ka ho kenya ts'ebetsong mekhoa ena e meng ea tlhahiso le ho ntlafatsa li-parameter tsa compression molding, o ka ntlafatsa haholo ts'ebetso ea hau ea tlhahiso. Ho fetola mohato oa bothata oa extrusion le ho sebelisa liforomo tsa pele ho fana ka tharollo e sebetsang le e laoloang haholoanyane. Ntle le moo, ho phenyekolla mekhoa e thehiloeng joalo ka SMC le forging e chesang ho fana ka khothatso ea bohlokoa. Re hoQiangshengplasba ikemiselitse ho tšehetsa katleho ea hau. Ha re ntse re sebetsa ka ho khetheha ho Mechini ea Extrusion ea PVC, re utloisisa sebopeho se pharalletseng sa tlhahiso ea lipolasetiki 'me re thabela ho arolelana tsebo le boitseanape ba rona. Haeba u na le lipotso tse ling kapa u hloka thuso ho ntlafatsa ts'ebetso ea hau ea tlhahiso, ka kopo u se ke oa tsilatsila ho ikopanya le rona.
