Tsebapanang Khahlanong le Rotang Twin Screw Extruder

Moralo oa li-screw tse ka morao-o batla o le bonolo. Ka lebaka la likurufu tse peli tse potolohang ka mahlakoreng a fapaneng 'me li na le lintlha tse fokolang lipakeng tsa tsona, litlhoko tse nepahetseng tsa ho lekana lipakeng tsa likurufu li batla li le tlase. Ka k'haontareng e potolohang mafahla-screw extruder, sepalangoang se tšoana le mokhoa o motle oa ho falla pompong ea gear. Tšobotsi ea extruder ena ke lebelo la eona le tlaase la ho potoloha, e leng ho fokotsa mocheso o hlahisoang ke ho kuta le ho fokotsa kotsi ea ho bola ha thepa. Ka hona, e na le litlhoko tse batlang li le tlaase bakeng sa botsitso ba mocheso oa thepa 'me e loketse ka ho khetheha bakeng sa ho bōptjoa le ho sebetsana le lisebelisoa tse nang le mocheso o kang PVC.

Mafahla a pota-potileng scruder extruder e na le bokhoni bo phahameng ba ho fetisa, ho ntša metsi ho betere le litlamorao tse qhibilihang. Leha ts'ebetso ea eona ea ho hasana le ho kopanya e le tlase hanyane, e ka theha khatello e tsitsitseng ea hlooho, e etsa hore e be khetho e nepahetseng bakeng sa extrusion e tobileng ea lihlahisoa. Ntle le moo, ts'ebetso ea granulation ea pele ho polasetiki e ka tloheloa mme phofo ea PVC e ka sebetsoa ka kotloloho ho fokotsa litšenyehelo tsa sehlahisoa.
Ka tloaelo, anisotropic conical twin-screw extruder e sebelisoa haholo bakeng sa lihlahisoa tsa polyvinyl chloride (PVC). Leha ho le joalo, lilemong tsa morao tjena, mekhoa e meng ea malapeng e bontšitse hore "anisotropic conical twin"-screw extruder e ka sebelisoa ka katleho ho extrusion ea polyolefin (e kang polyethylene, PE). Sepheo se seholo sa ho sebelisa lefahla la anisotropic conical-screw extruder ho ntša lipeipi tsa polyolefin ke ho boloka matla le ho fokotsa litšenyehelo.

Mohlala, bophara ba 65mm conical twin-screw extruder e nang le screw spacing ea 132um e na le motlakase oa motlakase oa 37kW feela, ha 75mm kapa 80mm single screw extruder hangata e na le matla a ho khanna a seng ka tlase ho 90kW. Sena se bolela hore, ka nako e ts'oanang kapa e ts'oanang, sesebelisoa sa "screw extruder" se pota-potang{8} se ka fana ka ts'ebeliso e ntle ea matla.
Ho bohlokoa ho elelloa hore ka lebaka la phapang e kholo lipakeng tsa phallo lipakeng tsa polyolefin melt le polyvinyl chloride melt, ha o sebelisa "anisotropic conical twin" e neng e entsoe qalong, -screw extruder bakeng sa PVC ho polyolefin pipe extrusion, moralo oa "screw" o hloka ho lokisoa ho netefatsa ts'ebetso e sebetsang ea lisebelisoa tsa polyolefin, 'me ho hlokahala hore ho be le liphetoho tse amanang le tsona.

Co rotating twin-screw extruder, ka lebaka la litšobotsi tsa eona tse ikhethileng le litaba tsa theknoloji e phahameng, e entsoe ka nepo le ho rarahana ho feta; Mabapi le tlhokomelo, nako le boiteko bo eketsehileng li hloka ho tseteloa tsamaisong e ntle. Mafahla a fapaneng-screw extruder e ratile basebelisi ba bang ka moralo oa eona o hloekileng le o hlakileng, haholo-holo maemong a ts'ebeliso a batlang botsitso le ts'epahalo.
Opposite rotating twin screw extruder ke sesebelisoa se ikhethileng se loketseng ho bopa ha li-powders tse fapaneng tsa PVC. E na le liforomo tse fapaneng le mechini e thusang, e ka hlahisa mefuta e fapaneng ea liphaephe tsa polasetiki tsa PVC, liprofaele, lipoleiti, lishiti, mekoallo le li-pellets.
