A extruder ea screw e nang le mahlakore a mabeli e kobehilengke mofuta oa sesebelisoa sa ho ntša li-screw tse peli se nang le li-screw tse peli tse hlophisitsoeng ka sebopeho sa khoune, tse thellang qetellong ea sesebelisoa sa ho ntša li-screw. Moralo ona o fana ka phokotso butle-butle bophahamong ba kanale ea sekere, e leng se fellang ka khatello e eketsehileng le ho ntlafala ha ho kopana. Sesebelisoa sa ho ntša li-screw tse peli se khoune se entsoe haholo-holo ka sekere sa barrel, sistimi ea phetisetso ea gear, phepelo ea bongata, mosi oa vacuum, ho futhumatsa, ho pholisa le likarolo tsa taolo ea motlakase.
Sesebelisoa sa ho ntša li-screw tse peli tse kobehileng se loketse ho hlahisa lihlahisoa tsa PVC ka phofo e tsoakiloeng. PVC ke polymer ea thermoplastic e nang le mefuta e mengata ea lits'ebetso liindastering tse fapaneng, joalo ka kaho, ho paka, motlakase, likoloi le bongaka. Leha ho le joalo, PVC ha e lumellane le li-polymer tse ling tse ngata le li-additives, 'me e hloka mekhoa e khethehileng ea ts'ebetso ho fihlela thepa le ts'ebetso e lakatsehang. Sesebelisoa sa ho ntša li-screw tse peli tse kobehileng se ka fana ka motsoako o hlokahalang, ho qhibiliha, ho qhaqha le ho kopanya PVC le li-additives tsa eona ka mokhoa o tsoelang pele le o sebetsang hantle.
Sesebelisoa sa ho ntša li-screw tse peli tse kobehileng le sona ke sesebelisoa se ikhethang bakeng sa ho ntša phofo ea WPC. WPC e emetse motsoako oa lehong-polasetiki, e leng thepa e kopanyang likhoele tsa lehong kapa phofo ea lehong le li-polymer tsa thermoplastic, tse kang PVC, PE, PP, kapa PLA. WPC e na le melemo ea lehong le polasetiki, joalo ka matla a phahameng, ho tšoarella, ho hanyetsa boemo ba leholimo le ho sebelisoa hape. Sesebelisoa sa ho ntša li-screw tse peli tse kobehileng se ka sebetsana le phofo ea WPC ka tlhahiso e phahameng, ts'ebetso e tsitsitseng le bophelo bo bolelele ba tšebeletso.
Ka disebediswa tse fapaneng tsa hlobo le tse theohelang tlase, sesebelisoa sa ho ntsha dikurufu tse pedi se ka hlahisa dihlahiswa tse fapaneng tsa PVC le WPC, tse kang diphaephe, disiling, diprofaele tsa difensetere, lakane, dideke le di-granule. Dihlahiswa tsena di na le dibopeho, boholo le mesebetsi e fapaneng, mme di ka fihlela ditlhoko tse fapaneng tsa bareki le mebaraka.
Tlhaloso ea Ts'ebetso
Ts'ebetso ea ho ntša li-screw tse peli tse kobehileng e ka aroloa ka mekhahlelo e mene e meholo: ho fepa, ho qhibilihisa, ho senya le ho bopa.
Ho fepa
Mokhahlelo oa pele oa ho ntša li-screw tse peli tse kobehileng ke ho fepa. Mokhahlelong ona, thepa e tala, joalo ka phofo ea PVC kapa WPC, le lintho tse ling tse tlatsetsang, joalo ka li-stabilizer, li-lubricant, li-filler, li-pigment le li-modifiers, li lekanngoa le ho fepuoa ka har'a extruder ke lisebelisoa tse fapaneng tsa ho fepa, joalo ka li-screw auger, literei tsa ho thothomela, mabanta a boima, le lipompo tsa ente. Sekhahla sa ho fepa le ho nepahala ke lintlha tsa bohlokoa tse amang boleng le botsitso ba lihlahisoa tsa ho qetela. Lisebelisoa tse tala li ka kopanngoa esale pele le ho fepuoa, kapa tsa lekanngoa ka thoko le ka tatellano ka har'a extruder, ho latela mokhoa le thepa e lakatsehang ea lihlahisoa.
Ho qhibiliha
Mokhahlelo oa bobeli oa ho ntša li-screw tse peli tse kobehileng o ntse o qhibiliha. Mokhahlelong ona, thepa e tala e tsamaisoa, e hatelloa, 'me e futhumatsoa ke li-screw tse potolohang le li-heater tsa libarele, 'me e fetoloa ho tloha boemong bo tiileng ho ea boemong ba metsi. Mokhahlelo oa ho qhibiliha o kenyelletsa ho kenngoa ha matla a mocheso le a mechini, 'me o susumetsoa ke lebelo la li-screw, mokhoa oa li-screw, mocheso oa libarele le thepa ea thepa. Mokhahlelo oa ho qhibiliha o boetse oa bohlokoa bakeng sa ho hasana le ho ajoa ha lintho tse ling tse ka har'a matrix ea polymer, le ho qalisoa ha liketso tsa lik'hemik'hale, tse kang ho kopanya, ho kopanya, kapa ho senyeha, tse ka bang teng ha ho qhibiliha. Mokhahlelo oa ho qhibiliha o tlameha ho laoloa ka hloko ho qoba ho chesa haholo, ho kuta ho feteletseng, kapa ho qhibiliha ha thepa, e leng se ka fellang ka boleng le ts'ebetso e mpe ea sehlahisoa.
Ho fetoha ha matla
Mokhahlelo oa boraro oa ho ntša li-screw tse peli tse kobehileng ke ho li tlosa. Mokhahlelong ona, likarolo tse feto-fetohang, tse kang mongobo, moea, li-monomer, li-solvents le lihlahisoa tsa ho bola, li tlosoa ho qhibiliha ka ho sebelisa vacuum likoung tsa moea tse haufi le moqomo oa extruder. Ts'ebetso ea ho li tlosa e bohlokoa bakeng sa ho ntlafatsa boleng ba sehlahisoa le botsitso, hammoho le ho fokotsa tšusumetso ea tikoloho le likotsi tsa bophelo bo botle tsa ts'ebetso ea ho li ntša. Ts'ebetso ea ho li tlosa e itšetlehile ka moralo oa li-screw, boemo ba vacuum, viscosity ea ho qhibiliha, le litšobotsi tsa thepa. Ts'ebetso ea ho li tlosa e tlameha ho ntlafatsoa ho fihlela ho tlosoa ho lekaneng ha li-volatiles ntle le ho baka foam e feteletseng, likhohola tsa moea, kapa ho senyeha ha ho qhibiliha.
Ho bopa
Mokhahlelo oa bone le oa ho qetela oa ho ntša li-screw tse peli tse kobehileng ke ho bopa. Mokhahlelong ona, ho qhibiliha ho ntšoa ka die kapa hlobo e khethollang sebopeho le boholo ba sehlahisoa. Die kapa hlobo e ka etsoa ho hlahisa lihlahisoa tse fapaneng, joalo ka liphaephe, liprofaele, lakane, filimi, kapa li-granule. Ts'ebetso ea ho bopa e susumetsoa ke geometry ea die, khatello ea die, mocheso oa die, le rheology ea ho qhibiliha. Ts'ebetso ea ho bopa e tlameha ho fetoloa ho fihlela li-extrudate tse tšoanang le tse boreleli ntle le liphoso, joalo ka ho ruruha ha die, ho robeha ha melt, kapa ho se tsitse ha boholo. Kamora ts'ebetso ea ho bopa, li-extrudate lia pholisoa, lia khaoloa, 'me li bokelloa ke lisebelisoa tse tlase, joalo ka li-calibrator, li-haul-offs, li-cutter le li-winder.
Qetello
Sesebelisoa sa ho ntša li-screw tse peli tse kobehileng ke sesebelisoa se sebetsang ka ho fetisisa le se sebetsang hantle bakeng sa ho hlahisa lihlahisoa tsa PVC le WPC ho tsoa phofong e tsoakiloeng. Se ka fana ka mesebetsi e hlokahalang ea ho fepa, ho qhibilihisa, ho senya le ho bopa ka mokhoa o tsoelang pele le o laoloang. Se ka boela sa hlahisa lihlahisoa tse fapaneng tse nang le libopeho, boholo le mesebetsi e fapaneng, ka ho sebelisa thepa e fapaneng ea hlobo le e ka tlase. Sesebelisoa sa ho ntša li-screw tse peli tse kobehileng se na le melemo ea ho kopanya hantle, tlhahiso e kholo, ho sebetsa ka botsitso le bophelo bo bolelele ba tšebeletso, 'me se ka fihlela litlhoko tse fapaneng tsa bareki le limmaraka.
