(1) Hoolauna omea hoʻokuke hoʻokahi screw
ʻO nā extruders hoʻokahi-screw, e like me ka inoa i hōʻike ʻia ai, hoʻokahi wili i loko o ka pahu extruder.ʻO ka maʻamau, ua māhele ʻia ka lōʻihi kūpono i ʻekolu mau ʻāpana, a ua hoʻoholo ʻia ka lōʻihi kūpono o nā ʻāpana ʻekolu e like me ke anawaena screw, pitch, a me ka hohonu o ka screw, a ua māhele ʻia e like me kēlā me kēia helu no ka hapakolu.
ʻO ka ʻāpana mua: e hoʻomaka ana mai ke kaula hope o ke awa hānai, ua kapa ʻia ʻo ia ka ʻāpana lawe.ʻAʻole koi ʻia ka mea ma ʻaneʻi e plasticized, akā pono e hoʻomaʻamaʻa mua ʻia a paʻi ʻia.I ka wā ma mua, ua manaʻo ka manaʻo extrusion kahiko he kino manuahi ka mea ma aneʻi.Ma hope mai, ua hōʻike ʻia ʻo ka mea ma ʻaneʻi he plug paʻa, ʻo ia hoʻi, ua ʻoki ʻia ka mea ma aneʻi.ʻO ke kua he paʻa e like me ka plug, no laila ʻoiai e hoʻopau i ka hana hoʻopuka, ʻo ia kāna hana.
(2) Ka hoʻohana ʻana i ka extruder wili hoʻokahi
Hoʻohana nui ʻia ka extruder hoʻokahi-screw i ka extrusion o nā paipu, nā pepa, nā papa, a me nā mea i hoʻopili ʻia, a me ka granulation o kekahi mau mea i hoʻololi ʻia.
(1) Hoolauna omāhoe-screw extruder
ʻO ka twin-screw extruder e pili ana i kēia mau ʻōnaehana.Hoʻopiha nui ka ʻōnaehana screw i ka plasticization a me ka lawe ʻana i ke kaʻina hana, he hopena nui i ka hana a me ka maikaʻi o ka huahana i hoʻopau ʻia.
① Pūnaehana hānai: me ka hopper, ka mīkini hoʻoulu, a me ka mīkini hānai.Hiki iā ia ke pale i ka hōʻiliʻili waiwai a hoʻomaʻamaʻa i kona komo ʻana i loko o ke awa hānai.
② Pūnaehana hoʻomehana waho: E hoʻohana nui i ke koʻokoʻo hoʻomehana a me ka cylinder e hoʻomehana maikaʻi i ka mea a hoʻoikaika i ka plasticization.
③ Pūnaehana hoʻoluʻu: ʻO ka ʻōnaehana hoʻololi wela i haku ʻia me ka ʻaila hoʻoili wela a i ʻole ka wai e hoʻemi i ka wela o ka fuselage, i mea e hoʻomalu pono ai i ka mahana o ka cylinder.
④ ʻōnaehana hoʻololi ʻana i ka pale hydraulic: E hoʻohana i nā pale kānana i hoʻololi ʻia e keakea i nā haumia, hoʻomaikaʻi i ke kiʻekiʻe o ka plasticization, a hōʻoia i ka kūlike a me ka paʻa o ka maikaʻi o nā mea hoʻopuka.
Laʻana hoʻohana o twin-screw extruder: ʻO ke aniani fiber i hoʻoikaika ʻia, ka granulation retardant flame (e like me PA6, PA66, PET, PBT, PP, PC reinforced flame retardant, etc.) (e like me PVC, XLPE cable material), mānoanoa waihoʻoluʻu masterbatch (e like me ka hoʻopiha ʻana i ka 50% toner), anti-static masterbatch, alloy, kala, haʻahaʻa hoʻopiha hoʻohui granulation, kelepona mea granulation (E like me sheath material, insulating material), XLPE paipu mea granulation (e like me masterbatch no ka wai wela crosslinking), thermosetting plastik hui 'ana a me ka extrusion (e like me phenolic resin, epoxy resin, pauka uhi), wela hooheheeia adhesive, PU reactive extrusion granulation (e like me EVA wela hooheheeia adhesive, polyurethane), K resin, SBS devolatilization granulation, etc.
Nā laʻana hoʻohana o ka extruder screw hoʻokahi:kūpono no nā paipu PP-R, nā paipu kinoea PE, nā paipu pili kea PEX, nā paipu alumini-plastic composite, nā paipu ABS, nā paipu PVC, nā paipu kumu kilika HDPE a me nā paipu hui like ʻole;kūpono no ka PVC, PET, PS, PP, PC a me nā ʻaoʻao ʻē aʻe a me nā papa, a me nā plastics ʻē aʻe e like me nā filament, nā koʻokoʻo, etc.;hiki ke hoʻopili i ka wikiwiki o ka extruder a me ka hoʻololi ʻana i ke ʻano o ka extrusion screw i ka hana ʻana o PVC a me polyolefins.A me nā ʻaoʻao plastic ʻē aʻe.
