Kenyelletso ea Mosi o Tlaase oa PVC Wire le Metsoako ea Lithapo
Mosi o tlaase oa PVC (Polyvinyl Chloride) terata le metsoako ea lithapo ke lisebelisoa tse khethehileng tsa thermoplastic tse etselitsoeng ho fokotsa mosi le khase e chefo nakong ea ho tuka. Sena se ba etsa khetho ea bohlokoa bakeng sa lits'ebetso moo polokeho ea mollo e tlang pele. Ka tloaelo e sebelisetsoa ho kenya letsoho le ho kenya jekete ka likhoele tsa motlakase, metsoako ena e fana ka likarolo tse 'maloa tsa bohlokoa:
Moetso:Metsoako ea PVC ea mosi o tlase e entsoe ka motsoako oa PVC resin, plasticizers (joalo ka dioctyl phthalate le tri-2-ethylhexyl trimellitate), li-flame retardants (mohlala, antimony trioxide, aluminium trihydrate, le zinc borate), stabilizers (calcium/zinc-based), li-filler (calcium carbonate), le lubricants carbonate.
Mehaho e Tlase ea Mosi:Ho fapana le PVC e tloaelehileng, e ka fokotsang ponahalo ho fihlela ho 90% ka metsotso e 30 feela ka lebaka la mosi o teteaneng, metsoako ea PVC ea mosi o tlaase e entsoe ho finyella litekanyetso tsa tšireletso tse kang BS EN 61034. Metsoako ena e lumella bonyane 60% phetisetso ea leseli nakong ea mollo, e ntlafatsa haholo ts'ireletso.
Lelakabe Retadancy: PVC ka tlhaho e na le thepa e thibelang malakabe ka lebaka la chlorine ea eona, e matlafatsoang ka li-additives tse ling tse thibelang lelakabe. Metsoako ena e kopana le litekanyetso tse thata tse kang IEC 60332-1-2, UL VW1, le E84 (flame spread index <25, smoke developed index <50).
Lisebelisoa:E sebelisoa hangata libakeng tse kotsi tse kang litsi tsa data, lithanele, lifofane, makareche a literene le meaho ea sechaba, terata ea mosi e tlaase ea PVC le metsoako ea lithapo li bohlokoa bakeng sa ho fokotsa likotsi tse amanang le mosi le mosi o chefo ha ho ka cha.
Mathata a Tloaelehileng a Ts'ebetso le Litharollo tsa Mosi o Tlaase oa PVC Wire le Metsoako ea Cable
Ho sebetsana le metsoako ea PVC ea mosi o tlaase ho kenyelletsa ho laola mathata a mangata, haholo-holo ka lebaka la ho hlophisoa ha bona ho rarahaneng. Ka tlase, re tšohla tse ling tsa litaba tse atileng haholo tsa ts'ebetso le tharollo ea tsona:
1. Phatlalatso e Phahameng ea Filler e Lebisang ho Tsamaea Hantle le Torque e Phahameng
Phephetso:Ho finyella thepa e tlaase ea mosi, metsoako ea PVC hangata e na le li-filler tse ngata tse sa tloaelehang tse kang aluminium trihydrate (ATH) kapa magnesium hydroxide (Mg(OH) ₂) - hangata 20-60% ka boima ba 'mele. Le ha li-filler tsena li fokotsa mosi le lelakabe, li ka eketsa viscosity, tsa fokotsa phallo, 'me tsa baka ho roala ha lisebelisoa.
Litharollo:
Kenyelletsa lithuso tsa ho sebetsa joalo ka mafura a kahare/ kantle (mohlala, calcium stearate, boka ba polyethylene, kapali-additives tsa silicone) ho 0.5-2.0 phr ho theola viscosity le ho ntlafatsa phallo.
Sebelisa li-extruder tse phahameng tsa L/D ho ntlafatsa ho kopanya le ho hasana ha li-filler.
Sebelisa litsamaiso tsa kneader tse nang le conical force feeding ho etsa bonnete ba hore li kopane.
Khetha li-filler tse nang le boholo bo laoloang ba likaroloana le liphekolo tsa bokaholimo ho ntlafatsa tšebelisano 'moho le ho fokotsa ho ruruha.
2. Thermal Stability
Phephetso:PVC e ka senyeha nakong ea ts'ebetso, haholo-holo ka li-filler tse phahameng le meroalo e thibelang malakabe, e ntša khase ea hydrogen chloride (HCl) e lebisang ho senyeha ha thepa, ho senyeha ha mebala le ho senyeha ha thepa.
Litharollo:
Eketsa li-stabilizers tsa mocheso tse kang calcium / zinc-based stabilizers ho 2-4 phr ho fokotsa HCl le ho thibela ho senyeha.
Sebelisa oli ea soya e nang le epoxidized (ESO) e le motsoako oa "stabilizer" bakeng sa ho ntlafatsa mocheso le ho tsitsa ha lifoto.
Laola mocheso oa ho sebetsa hantle (160-190 ° C) ho qoba mocheso o feteletseng.
Kenyelletsa phenolic antioxidants (mohlala, Bisphenol A ho 0.3-0.5%) ho matlafatsa ho hanyetsa botsofali nakong ea ts'ebetso.
3. Phallo ea Plasticizer
Phephetso:Li-plasticizers tse sebelisetsoang ho ntlafatsa ho tenyetseha li ka falla tlas'a mocheso o phahameng (mohlala, litsing tsa data), tse lebisang ho bokelleng ha masala ho ka sitisang phetisetso ea matšoao kapa ho fokotsa nako e telele ea cable.
Litharollo:
Sebelisa li-polymeric tse sa falleeng ho e-na le tse monomeric (mohlala, DOP, DINP) ho fokotsa ho falla.
Theha liforomo tsa "no-liquid" tsa plenum, joalo ka ha li qalile ke OTECH, ho thibela ho falla ha plasticizer libakeng tse nang le mocheso o phahameng.
Khetha li-plasticizers tse kang TOTM, tse nang le maemo a tlaase a fokolang 'me li loketse haholo bakeng sa lisebelisoa tse phahameng tsa mocheso.
4. Ho Leka-leka-lekanya Lelakabe la Khalefo le Khatello ea Mosi
Phephetso:Ho eketsa ho lieha ha lelakabe ka li-additives tse kang antimony trioxide (3-5%) kapa metsoako ea brominated (12-15%) ho ka eketsa tlhahiso ea mosi, e leng ho etsang hore ho be thata ho leka-lekanya thepa ka bobeli. Ka mokhoa o ts'oanang, li-fillers tse kang calcium carbonate li ka fokotsa mosi empa li ka fokotsa index ea oksijene, 'me tsa ama lelakabe le liehang.
Litharollo:
Sebelisa metsoako e thibelang malakabe a synergistic (mohlala, ATH e nang le zinki borate) ho ntlafatsa ho lieha ha lelakabe le khatello ea mosi. Ka mohlala, ATH e ntša mouoane oa metsi ho sitisa ho tuka le ho etsa lesela le sireletsang la char, le fokotsang mosi.
Fokotsa ho jara ha CaCO₃ ho 20-40 phr ho fumana tekatekano lipakeng tsa litšenyehelo, khatello ea mosi, le ho lieha ha lelakabe, kaha chelete e ngata haholo e ka fokotsa index ea oksijene.
Lekola liforomo tsa PVC tse hokahantsoeng, joalo ka radiation cross-linked PVC, ho matlafatsa ho lieha ha lelakabe ntle le ho its'epa haholo ka li-additives tsa halogenated.
5. Tshebetso le Boleng ba Sefahleho
Phephetso:Li-filler tse phahameng le lintho tse tlatselletsang li ka lebisa pheletsong e mpe ea bokaholimo, die drool, le extrusion e sa tsitsang, e amang ponahalo le ts'ebetso ea sehlahisoa sa ho qetela sa cable.
Litharollo:SebelisaSILIKE silicone Powder LYSI-100A. Senasilicone e thehiloeng ho eketsae sebelisoa haholo joalo kasehlomathisi se sebetsang hantle sa ho sebetsa ka lubricantbakeng sa litsamaiso tsa resin tse lumellanang le PVC ho ntlafatsa thepa ea ts'ebetso le boleng ba bokaholimo. Joalo ka phallo e ntle ea resin, ho tlatsoa ha hlobo le ho lokolloa, torque e nyane ea extruder, le khohlano e tlase ea khohlano, mar e kholo, le ho hanyetsa abrasion…
1) Mosi o tlaase oa PVC terata le metsoako ea cable: extrusion e tsitsitseng, khatello e fokolang ea lefu, bokaholimo bo boreleli ba terata & thapo.
2) Khohlano e tlase ea mohala le mohala oa PVC: Coefficient e tlase ea Friction, maikutlo a boreleli a tšoarellang nako e telele.
3) Sehlahisoa sa PVC se manganga: Anti-scratch, joalo ka li-shutter tsa PVC.
4) Litlaleho tsa PVC: ho tlatsoa ha hlobo ho molemo le ho lokolloa ha hlobo, ha ho na khanya ea hlobo.
5) Pipe ea PVC: lebelo la extrusion ka potlako, COF e fokotsehileng, boreleli bo ntlafetseng, le litšenyehelo tse bolokiloeng.
Haeba u tobane le mathata a ho sebetsa ha metsoako ea PVC le mathata a holim'a metsi, kapa ho loantšana le terata ea PVC e sa tsubeng le ho sebetsa lithapo, leka.LYSI-100A Silicone Powder bakeng sa extrusion e boreleli le katleho e phahameng.
