Lisosa tsa Metso Ts'ebetsong ea Extrusion

Mabaka a 'maloa a ka sitisa phepelo ea lintho tse bonahalang ho extrusion ea pipe ea PVC.

1. Mathata a ho fepa, joalo ka li-hopper tse se nang letho kapa borokho, a bolaea screw mme a theha phepelo e sa tsitsang.
2. Ho apara ka mechine, joalo kadikurufu tse senyehileng kapa dibarele, e fokotsa bokhoni ba extruder ea ho tsamaisa thepa hantle.
3. Boemo ba mocheso o sa nepahalang bo ka baka ho qhibiliha pele ho nako kapa ho thibela, ho baka ho phahama le ho feto-fetoha ha tlhahiso.
4. Li-hopper tse koalehileng li thibela phallo ea thepa e tala, ha mathata a tsamaiso ea li-feeder drive, joalo ka motor kapa gear errors, a lieha kapa a emisa ho fepa.
5. Lintho tse nang le mongobo kapa tse sa tsitsang linthong tse tala li atoloha mochesong o phahameng, li baka lipudula tsa moea le likoli.
6. Litšila le boholo bo sa lekaneng ba likaroloana linthong tse tala li lebisa mochesong o sa lekaneng le li-bubble tse ngata tsa moea.
7. Phapang ka sebopeho le boholo ba resin ea PVC, haholo-holo pakeng tsa lisebelisoa le lisebelisoa tsa boroetsana, li ama fusion le viscosity e qhibilihisang, e bakang lijo tse sa tšoaneng.

Keletso:Ho omisa ka mokhoa o tsitsitseng le ho hlahloba thepa e talathusa ho thibela mathata a mangata a fepa le ho ntlafatsa botsitso ba extrusion.

PVC Pipe Screw Barrel bakeng sa Extrusion: Tharollo bakeng sa Fepelo e Tšoanang ea Material

Meetso ea Multi-Stage Screw le Melemo ea Tsona

Meralo ea li-screw tsa mekhahlelo e mengata e bapala karolo ea bohlokoa ho ntlafatseng phepelo ea thepa nakong ea extrusion ea pipe ea PVC. Meetso ena, joalo ka li-barrier screws le li-venting screws, li arola likurufu ka libaka tse ikhethileng. Sebaka se seng le se seng se etsa mosebetsi o itseng, joalo ka ho qhibiliha, ho kopanya, kapa ho tlosa likhase. Li-barrier screws li arola lintho tse tiileng le tse qhibilihisitsoeng, e leng se lebisang ho ntlafalang ha ho qhibiliha le tšebeliso e tlase ea matla. Li-screw tsa moea li kenyelletsa libaka tsa decompression tse tlosang likhase le mongobo, e leng se bakang liphaephe tse nang le likheo tse fokolang le tsa boleng bo holimo.

Li-extruder tsa li-twin screw, haholo-holo tse nang le meralo e pota-potileng, li ntlafatsa ho kopanya le ho hasana ha li-additives. Ntlafatso ena e lebisa ho ts'ebeliso e ntle ea mebala le matla a mochini sehlahisoa sa ho qetela. Hangata bahlahisi ba bona tlhahiso e phahameng le tlhahiso e ntlafetseng ha ba sebelisa meralo ena e tsoetseng pele ea screw. Mohlala, ho fetohela ho sekurufu se fofang se le seng ho ea ho "barrier screw" ho ka eketsa botsitso ba thepa le ho fokotsa tšebeliso ea matla ka 15%. Ho ntlafatsa bophara ba screw le ho kopanya litsamaiso tse tsoetseng pele tsa taolo ho eketsa boleng le katleho ea extrusion.

Tlhokomeliso: Meralo ea li-screw tsa mekhahlelo e mengata ka har'a PVC Pipe screw barrel bakeng sa extrusion e thusa ho boloka litefiso tse tsitsitseng tsa phepo le ho fokotsa kotsi ea likoli, e leng khetho e ratoang bakeng sa tlhahiso ea liphaephe tsa boleng bo holimo.

Ntlafatsa Screw Geometry le Compression Ratios

Screw geometry e ama ka kotloloho tsela eo lintho li tsamaeang, li qhibilihang le ho tsoakana kahare ho extruder. Moralo o kenyelletsa liparamente tse kang botebo ba kanale, sekontiri se phahameng, le karo-karolelano ea bolelele ho isa ho bophara. Geometry e nepahetseng e netefatsa hore lintho tse tiileng li tsamaisana hantle le ho thibela mathata a kang ho borokho kapa ho phunya. Karolo e 'ngoe le e' ngoe ea screw-feed, compression, le metering-e na le sebopeho se itseng se lumellanang le thepa ea PVC.

Karo-karolelano ea khatello, e leng karo-karolelano ea botebo ba kanale ea phepelo ho botebo ba kanale ea metering, e phetha karolo ea bohlokoa ho qhibiliheng homogeneity le throughput. Karo-karolelano ea khatello e khethiloeng hantle e tiisa ho qhibiliha ho tšoanang le ho phalla ha thepa e tsitsitseng. Likhatello tse phahameng tsa khatello li eketsa khatello le ho ntlafatsa ho kopanya, e leng se lebisang ho boleng bo botle ba sehlahisoa. Leha ho le joalo, haeba karo-karolelano e phahame haholo kapa e le tlase haholo, e ka baka phallo e sa tsitsang le mefokolo. Ho fetola karo-karolelano ea compression ho ipapisitsoe le thepa le liparamente tsa ts'ebetso ho thusa ho ntlafatsa ts'ebetso.

Baetsi ba boetse ba rua molemo ka ho beha leihlo khafetsa le tlhokomelo ea screw geometry. Moralo o sa fetoheng oa screw le sebaka se nepahetseng lipakeng tsa screw le barrel li fokotsa ho khathala le ho boloka phepelo e tšepahalang. PVC Pipe screw barrel bakeng sa extrusion hangata e na le geometry e hlophisitsoeng ho tsamaisana le litlhoko tse ikhethang tsa tlhahiso, e ts'ehetsa ts'ebetso e tsitsitseng le tlhahiso ea boleng bo holimo.

Mekhoa ea ho Fella Moqomo le Taolo ea Mocheso

Sistimi ea ho kenya moea ka meqomong e bohlokoa bakeng sa ho tlosa moea, mongobo le lintho tse sa tsitsang ho tsoa ho polymer melt. Ho kenyelletsa boema-kepe ka har'a barrel ea extrusion ho ka fokotsa mongobo o tsoang ho extrudate ho tloha ho feta 3-7% ho ea tlase ho 1%. Sebaka se nepahetseng sa moea, haholo-holo ka mor'a sebaka sa ho qetela sa ho kopanya, se lumella ho tlosoa ka katleho ha li-volatile. Mokhoa ona o thibela ho thibela phepelo le ho ntlafatsa boleng ba phala ea ho qetela.

Basebelisi ba tlameha ho etsa bonnete ba ts'ebetso e nepahetseng le tlhokomelo e nepahetseng ea lisebelisoa tsa moea ho qoba mathata a kang ho qhibiliha ha moea o tsoa. Ho sebelisa li-vent stuffer ho ka thusa ho thibela ho phonyoha ha polymer ha o ntse o lumella likhase ho tsoa. Ts'ebetso e tsitsitseng ea moea e itšetlehile ka ho boloka tekanyo e tlase ea ho tlala sebakeng sa moea le sekoti se tlatsitsoeng holimo ho sebetsa e le tiiso e qhibilihang.

Taolo e nepahetseng ea mocheso ka har'a barrel e bohlokoa ka ho lekana. Ho boloka boemo bo nepahetseng ba mocheso ho thibela ho senyeha ha thepa le ho netefatsa boleng bo tsitsitseng ba ho qhibiliha. Mekhoa e tsoetseng pele ea ho futhumatsa le ea ho pholisa, joalo ka lihlopha tsa ho futhumatsa ka motlakase tse nang le taolo ea PID le ho pholisa metsi, li lumella ho laola mocheso o hlophisitsoeng hantle. Lisebelisoa tsena li thusa ho laola mocheso oa ho kuta o hlahisoang nakong ea extrusion, e leng ho ka bakang ho futhumala ha libaka le ho hloka botsitso lijong tsa lintho tse bonahalang. PVC Pipe screw barrel bakeng sa extrusion hangata e kenyelletsa likarolo tsena tse tsoetseng pele tsa ho kenya moea le ho laola mocheso, ho tšehetsa phepelo e tsitsitseng le boleng ba sehlahisoa se phahameng.

Keletso: Kamehla hlahloba lisensara tsa mocheso le lisebelisoa tsa moea ho boloka maemo a nepahetseng a extrusion le ho thibela ho theoha ho sa lebelloang.

Liphetoho tsa Ts'ebetso le Tlhokomelo ea Lijo tse Tšepahalang

Ho Lokisa Thempereichara, Lebelo la Screw, le Sekhahla sa Phepelo

Basebelisi ba fumana lijo tse tsitsitseng ka ho lokisa mocheso ka hloko, lebelo la screw, le sekhahla sa phepelo. Ho boloka mocheso o tsitsitseng oa ho qhibiliha ho thibela liphetoho tsa viscosity le phallo, tse ka bakang marako a liphaephe a sa lekaneng. Ho lokisa lebelo la sekoti ho laola ho kopanya le ho kuta, ho ama ka kotloloho matla a liphaephe le boleng ba bokaholimo. Tafole e ka tlase e akaretsa kamoo liparamente tsena li susumetsang ts'ebetso ea extrusion:

Basebelisi ba boetse ba lekanya li-sensor le li-control ho netefatsa lintlha tse nepahetseng le ts'ebetso e tsitsitseng. Sistimi e tsoetseng pele ea taolo e nang le taolo ea profil ea auto e thusa ho lebella le ho lokisa liphapang tsa tšebetso.

Ho beha leihlo le ho sebetsana le Screw le Barrel Wear

Ho roaloa ha screw le barrel ho ka senya lijo le boleng bo tlase ba sehlahisoa. Tlhahlobo ea khafetsa e lemoha matšoao a pele a kang ho fokotseha ha tlhahiso, ho lutla ha thepa, kapa tšebeliso e phahameng ea matla.
