(1) Nhanganyaya yesingle screw extruder
Single-screw extruder, sekureva kunoita zita, iva ne screw imwe mukati me extruder barrel.Kazhinji, hurefu hunoshanda hunopatsanurwa kuita zvikamu zvitatu, uye hurefu hunoshanda hwezvikamu zvitatu hunotarwa zvichienderana nescrew diameter, pitch, uye screw deep, uye kazhinji inopatsanurwa zvichienderana ne accounting yega yega chetatu.
Chikamu chekutanga: kutanga kubva patambo yekupedzisira yechiteshi chekudya, inonzi chikamu chekutumira.Izvo zvinhu pano hazvidiwi kuve zvepurasitiki, asi zvinofanirwa kuve zvakafanopiswa uye kusvinwa.Munguva yakapfuura, yekare extrusion theory yaitenda kuti zvinhu pano muviri wakasununguka.Gare gare, zvakazoonekwa kuti zvinhu zviri pano ipulagi yakasimba, zvinoreva kuti zvinhu zviri pano zvakasvinwa.Kumashure kwakasimba seplug, saka chero bedzi ichipedzisa basa rekutumira, ndiro basa rayo.
(2) Kushandiswa kweimwe screw extruder
Iyo single-screw extruder inonyanya kushandiswa mukuwedzeredza kwepombi, mashiti, mahwendefa, uye maprofile zvinhu, uye granulation yezvimwe zvakagadziridzwa zvinhu.
(1) Nhanganyaya yetwin-screw extruder
Iyo twin-screw extruder inosanganisira zvinotevera masisitimu.Iyo screw system inonyanya kupedzisa plasticization uye nzira yekufambisa yezvinhu, iyo ine simba guru pakuita uye kunaka kwechigadzirwa chakapedzwa.
① Sisitimu yekudyisa: inosanganisira hopper, inomutsa mota, uye yekudyisa mota.Inogona kudzivirira kuunganidzwa kwezvinhu uye kufambisa kupinda kwayo kwakatsetseka muchiteshi chekudya.
② Yekunze yekudziya sisitimu: Kunyanya shandisa yekudziya tsvimbo uye silinda kupisa zvinhu zvakanaka uye kukurudzira plasticization.
③Kutonhodza sisitimu: Iyo yekutsinhana kupisa inoumbwa nemafuta ekuchinjisa mafuta kana mvura inoshandiswa kuderedza kupisa kwefuselage, kuitira kunyatso kudzora tembiricha yecylinder.
④ Hydraulic screen inoshandura sisitimu: Shandisa inotsiviwa mafirita skrini kubata kusvibiswa, kuvandudza dhigirii repurasitiki, uye kuve nechokwadi chekufanana uye kugadzikana kwemhando yezvinhu zvinobuda.
Muenzaniso wekushandisa wetwin-screw extruder: girazi faibha yakasimbiswa, murazvo unodzoreredza granulation (yakadai sePA6, PA66, PET, PBT, PP, PC yakasimbisa murazvo wemoto, nezvimwewo), yakakwirira filler granulation (senge PE, PP yakazadzwa ne75% CaCO3), kupisa-sensitive zvinhu granulation. (zvakadai sePVC, XLPE cable material), gobvu ruvara masterbatch (sekuzadza 50% toner), anti-static masterbatch, alloy, coloring, low filling blend granulation, cable material granulation (Senge sheath material, insulating material), XLPE pombi zvinhu granulation (senge masterbatch yemvura inopisa crosslinking), thermosetting epurasitiki kusanganisa uye extrusion (senge phenolic resin, epoxy resin, poda coating), inopisa kunyunguduka adhesive, PU reactive extrusion granulation (senge EVA inopisa nyunguduka adhesive, polyurethane), K resin, SBS devolatilization granulation, nezvimwe.
Mienzaniso yekushandisa ye single screw extruder:inokodzera mapaipi ePP-R, PE gasi pombi, PEX-yakabatana mapaipi, aruminiyamu-plastiki inoumbwa mapaipi, mapaipi eABS, mapaipi ePVC, mapaipi epombi e-HDPE silicon core uye mapaipi akasiyana-siyana akabatanidzwa;yakakodzera PVC, PET, PS, PP, PC uye mamwe maprofile uye mahwendefa, uye mamwe mapurasitiki senge filaments, tsvimbo, nezvimwewo;kugadzirisa kumhanya kweiyo extruder uye kushandura chimiro cheiyo extrusion screw inogona kuiswa pakugadzirwa kwePVC uye polyolefins.Uye mamwe mapepa epurasitiki.
