Single Screw Barrel bakeng sa PE Film Extrusion

Nanhaiya ke setsebimoetsi oa moqomo o le mong oa screw China, e sebetsanang le litharollo tse ikhethileng tsa screw le barrel bakeng sa extrusion ea filimi ea polyethylene. Ka lilemo tse fetang 10 tsa boiphihlelo ba tlhahiso, re fana ka boenjiniere bo nepahetsengLi-Barrel tsa Screw tse le 'ngoe bakeng sa PE Film Extrusion, e etselitsoeng ho lumellana le lisebelisoa tse fapaneng tsa polyethylene, litlhophiso tsa extruder le litlhoko tsa tlhahiso. Litharollo tsa rona li koahela li-screw geometry, lisebelisoa tsa barrel, kalafo ea bokaholimo le boholo bo ikhethileng ba lisebelisoa, tse ts'ehetsang mela e mecha ea extrusion le merero ea ho khutlisa screw barrel. Sehlahisoa se seng le se seng se etsoa ho latela litšoantšo tse amohetsoeng tsa tekheniki le litlhaloso tsa mochini.

Likopo ho Tlhahiso ea Filimi ea Polyethylene

TheSingle Screw Barrel bakeng sa PE Film Extrusione sebelisoa mehala ea tlhahiso ea lifilimi ea polyethylene e sebetsanang le lisebelisoa tsa LDPE, LLDPE le HDPE. Likarolo tse fapaneng tsa resin li na le litšobotsi tse fapaneng tsa ho qhibiliha, boitšoaro ba phallo le litlhoko tsa ts'ebetso, tse susumetsang screw geometry, compression ratio le tlhophiso ea moqomo.

Bakeng sa extrusion e tsitsitseng ea filimi, screw le barrel li hloka ho sebetsa hammoho ho fana ka thepa e tsitsitseng e tsamaisang, ho qhibiliha, polasetiki le khatello ea ho qhibiliha. Tlhophiso e nepahetseng e ipapisitse le sehlopha sa resin, botenya ba filimi, lebelo la tlhahiso, mokhoa oa ho fepa, sebopeho sa extruder le tlhahiso ea sepheo. Nanhaiya e fana ka litharollo tse ikhethileng tsa PE filimi extruder screw barrel tse ipapisitseng le lintlha tsa 'nete tsa lisebelisoa le maemo a ts'ebetso.

Litlhaloso tsa Tekheniki

Nanhaiya e fana ka likhetho tse fapaneng tsa kalafo le holim'a sefahleho bakeng sa libarele tse le 'ngoe tsa screw ho latela litlhoko tsa ts'ebetso. Litlhaloso tse latelang li sebetsa e le sesupo sa tekheniki bakeng sa tlhahiso ea PE ea filimi ea extrusion screw barrel. Mekhahlelo ea ho qetela e ka netefatsoa ho latela moralo oa mochini, litlhoko tsa thepa le lits'oants'o tsa tekheniki tse lumellaneng.

Screw Geometry le Ts'ebetso ea Plasticizing

Screw geometry ke ntlha ea bohlokoa ho extrusion ea filimi ea polyethylene hobane e susumetsa phetisetso ea resin, ts'ebetso ea ho qhibiliha, ho kopanya le botsitso ba khatello. Sekurufu sa tloaelo se le seng ka kakaretso se na le likarolo tsa ho fepa, ho hatella le ho etsa metara, e 'ngoe le e 'ngoe e etsa mosebetsi o fapaneng nakong ea ts'ebetso ea extrusion.

Karolo ea ho fepa e fana ka resin e tiileng ea PE ka har'a barrel, ha karolo ea compression butle-butle e khothalletsa ho qhibiliha le ho kopana ha thepa. Karolo ea metering e thusa ho boloka phepelo e tsitsitseng ea ho qhibiliha le khatello pele thepa e kena ka extrusion die. Ho ipapisitsoe le maemo a resin le litlhoko tsa tlhahiso, likarolo tse ling tsa ho kopanya li ka nahanoa.

Ha u khetha aPE filimi extruder screw barrel, lintlha tsa bohlokoa tsa moralo li kenyelletsa bophara ba sekoti, karo-karolelano ea L / D, karo-karolelano ea khatello, botebo ba mocha, lebelo la screw le tlhophiso ea libaka tsa ho futhumatsa. Litlhaloso tsena li lokela ho hlahlojoa hammoho le sistimi ea extruder drive le lisebelisoa tsa tlhahiso ea lifilimi tse tlase. Moralo o loketseng oa screw o thusa ho theha maemo a tsitsitseng a ts'ebetso bakeng sa lits'ebetso tse fapaneng tsa filimi ea polyethylene.

Lisebelisuoa tsa Barel le Liphekolo tse Thibelang ho Rua

Khetho ea thepa e ama bophelo ba ts'ebeletso le ts'ebetso ea ts'ebetso ea PE ea filimi ea extrusion screw barrel. Thepa e nepahetseng le kalafo ea holim'a metsi e lokela ho khethoa ho latela litšobotsi tsa resin, mocheso oa ho sebetsa, khatello ea ts'ebetso, li-additives le maemo a lebelletsoeng a ho apara.

38CrMoAlA ke tšepe ea alloy e sebelisoang hangata bakeng sa screw ea nitrided le likarolo tsa barrel. Kalafo ea nitriding e ka ntlafatsa ho thatafala ha holim'a metsi le ho hanyetsa ho apara. Bakeng sa lits'ebetso tse kenyelletsang li-fillers tsa abrasive, lisebelisoa tse nchafalitsoeng kapa maemo a ts'ebetso a batlang ho feta, meaho ea meqomo ea bimetallic le likhetho tse ling tse sa sebetseng li ka hlahlojoa ho latela litlhoko tsa 'nete tsa ts'ebetso.

Chrome plating ke khetho e 'ngoe ea kalafo ea holim'a metsi bakeng sa likarolo tse loketseng tsa screw le barrel. Khetho ea nitriding, chrome plating kapa ts'ireletso ea bimetallic e lokela ho ipapisa le sebopeho sa karolo, tikoloho ea ts'ebetso le lintlha tse hlokahalang tsa tekheniki ho fapana le ho sebelisa kalafo e tšoanang ts'ebelisong e 'ngoe le e' ngoe ea extrusion.

Precision Manufacturing le Quality Inspection

Ho nepahala ha sekoti se le seng sa screw barrel ho ama ka ho toba tumello e ts'oanang lipakeng tsa screw le barrel, thepa e tsamaisang le botsitso ba extrusion. Nanhaiya e etsa likaroloana tsa screw le barrel ho latela litšoantšo tse amohetsoeng le litlhoko tsa tekheniki tse lumellanoeng, ho ela hloko ho nepahala ha machining le boemo ba bokaholimo.

Ts'ebetso ea ho etsa tlhahiso e ka kenyelletsa ho lokisa thepa, ho sebetsa ka thata, ho phekola mocheso, ho sebetsa ka nepo, ho qeta sefofane sa screw le kalafo ea holim'a metsi. Lintho tsa tlhahlobo li ka kenyelletsa bophara ba screw, profil ea sefofane, bophara ba barrel bore, ho otloloha, concentricity, litekanyo tsa khokahano, clearance e bapisang le bokaholimo bo thata.

Bakeng sa libarele tsa screw extrusion tsa PE tse ikhethileng, litekanyo tsa bohlokoa le lintlha tsa tekheniki li lokela ho netefatsoa pele ho tlhahiso. Ho hlahlojoa ha litekanyo tse mahlonoko le maemo a holim'a metsi ho thusa ho etsa bonnete ba hore likarolo tse phethiloeng li finyella litlhoko tse lumellanoeng bakeng sa ho kenya lisebelisoa le ho sebetsa.

Custom Single Screw Barrel le Replacement Solutions

Li-extruder tse fapaneng tsa lifilimi tsa PE li na le li-diameter tse fapaneng tsa screw, li-ratios tsa L / D, matla a koloi, litokisetso tsa ho futhumatsa, litekanyo tsa khokahano le bokhoni ba tlhahiso. Liphapang tsena li etsa hore lisebelisoa li tsamaellane e be taba ea bohlokoa ha u reka sekoti se le seng se ikhethileng kapa u nkela likarolo tse teng tsa extrusion sebaka.

Nanhaiya e fana ka tlhahiso ea "screw barrel" e tloaelehileng e ipapisitseng le litšoantšo tsa mochini, lisampole tsa karolo ea mantlha le litlhaloso tsa tekheniki. Hore na o hloka screw e felletseng le kopano ea barrel, screw ea motho ka mong kapa barrel e ikhethileng, litekanyo le tlhophiso li ka hlahlojoa ho latela lisebelisoa tse teng.

Pele o netefatsa taelo ea tlhahiso ea moetlo, lintlha tse latelang tsa tekheniki li lokela ho hlahlojoa:

• Moetsi oa Extruder le mohlala oa mochini
