PE Conical Twin Screw Barrel

Sebaka sena sa PE conical twin screw barrel se entsoe ka tšepe ea 38CrMoAla. Lintho tse tala li bohlokoa haholo bakeng sa ts'ebetso ea "screw", 'me re khetha litšepe tse matla le tse sa senyeheng ho tsoa ho baetsi ba litšepe ba tsebahalang ba Machaena ba fihlelang maemo a naha (GB/T 3077).

Nanhaiya's PE conical twin screw barrel hangata e etsoa ho tsoa ho litšepe tsa boleng bo holimo tse kang 38CrMoAlA, tse fanang ka moaparo o motle haholo le ho hanyetsa kutu le matla a mocheso o phahameng. Nitriding le lits'ebetso tse ling li ntlafatsa ho thatafala ha holim'a metsi le ho hanyetsa ho roala, ho lelefatsa bophelo ba ts'ebeletso. Moqapi oa conical twin-screw barrel o khothalletsa litšobotsi tse tsitsitseng tsa phallo. Ka ho etsa bonnete ba hore phepelo e tsitsitseng le khatello nakong eohle ea ts'ebetso ea extrusion, sena se thusa ho fokotsa likhaello tsa phallo joalo ka ho feto-fetoha kapa ho phunya, ho fokotsa ts'ebetso ea lisebelisoa le ho lelefatsa bophelo ba ts'ebeletso ea screw le barrel.

Libarele tsa Nanhaiya's PE conical twin screw barrel li entsoe ka R&D tse ngata le lintlafatso 'me joale li kopantsoe mehala ea tlhahiso ea bahlahisi ba fapaneng, ho fihlela ts'ebetso ea maemo a holimo. Re fana ka tiisetso ea lilemo tse 1-2, ho latela tekanyo e khethehileng ea tlatsetso ea thepa. Libarele tsa Nanhaiya li kena tšebetsong ea nitriding, tse nang le lesela le tenya la 2mm la nickel-tungsten alloy alloy-welded libakeng tse tloaelehileng haholo. Sena se eketsa boima ba holim'a barrel ho tloha ho HRC55-60 ho ea ho HRC65, ho matlafatsa khanyetso ea ho apara ka makhetlo a 2-4.

Paramethara (Tlhahiso)

Tšobotsi le Tšebeliso

Li-extruder tsa PE conical twin screw li na le moralo o pota-potileng (likurufu tse peli li potoloha ka mahlakoreng a fapaneng). Sena se etsa hore ho be le lekhalo le lenyenyane la li-intermeshing, ho hlahisa matla a matla a ho kuta (ho khothalletsa PE plasticization) ha ho ntse ho lumella lifofane ho hloekisana (ho fokotsa masala a thepa le ho thibela ho senyeha).

Nanhaiya's PE conical twin screw extruders e na le sebaka se senyenyane pakeng tsa lifofane tse fofang le lebota la moqomo (ka tloaelo 0.1-0.3mm). Ha li kopantsoe le ho kuta le litlamorao tsa extrusion tse hlahisoang ke li-screws tse potolohang, li qhibilihisa li-granules tsa PE ka potlako le ho qhala li-additives (tse kang li-antioxidants le li-colorants). Moralo oa screw o fana ka sebaka sa li-vents le li-filters tse qhibilihang, tse li lumellang hore li sebetse le sistimi ea moqomo ho tlosa mongobo le limolek'hule tse tlase tsa boima ba limolek'hule ho tsoa ho PE ho qhibiliha, ho netefatsa sehlahisoa se senang bubble. Lisefe tsa boholo bo fapaneng ba masoba le tsona li ka sebelisoa ho sefa litšila le ho ntlafatsa bohloeki ba sehlahisoa.

The PE conical twin screw barrel e lumellana le mefuta e sa tšoaneng ea lisebelisoa tse tala tsa PE: LDPE (polyethylene e tlaase-density), HDPE (polyethylene e phahameng haholo), LLDPE (linear low-density polyethylene), le mefuta e meng ea PE. Ka ho lokisa lebelo la screw le li-parameter tsa groove, e ka amohela lisebelisoa tse tala tsa PE tse nang le li-index tse fapaneng tsa ho qhibiliha. E ka sebelisoa bakeng sa extrusion ea liphaephe tsa PE, profiles, le lifilimi, hammoho le PE pelletization le phetoho (joalo ka khalase ea fiber e matlafatsang le phetoho e thibelang malakabe). E loketse ka ho khetheha bakeng sa tlhahiso ea lihlopha tse nyenyane le mefuta e mengata ea lihlahisoa tsa PE.

Lintlha tsa Sehlahisoa

Mekhoa e tsoetseng pele ea ho futhumatsa, ho sebetsa ka mokhoa o nepahetseng, le lits'ebetso tsa nitriding li netefatsa ts'ebetso e felletseng ea likarolo tsa mantlha.

Libaka tse tlokotsing tsa screw le barrel li matlafatsoa ka lera la nickel-tungsten alloy, ho fihlela lera le teteaneng la 2-3mm le ho ntlafatsa haholo ho hanyetsa ho apara.
