(1) Folasaga oextruder sikulima tasi
O mea fa'apipi'i fa'alila e tasi, e pei ona ta'u mai e le igoa, e tasi le fa'a sikuila i totonu o le pa'u fa'ameamea.E masani lava, o le umi aoga e vaevaeina i ni vaega se tolu, ma o le umi aoga o vaega e tolu e fuafuaina e tusa ai ma le lautele o le sikulima, pitch, ma le loloto o le sikulima, ma e masani ona vaevaeina e tusa ai ma faʻamaumauga taʻitasi mo le tasi vaetolu.
O le vaega muamua: amata mai le filo mulimuli o le taulaga fafaga, e taʻua o le vaega o le felauaiga.O mea iinei e le manaʻomia e faʻapipiʻiina, ae tatau ona faʻamafanafana ma oomi.I aso ua tuanaʻi, o le talitonuga tuai o le extrusion na talitonu o le mea iinei o se tino matala.Mulimuli ane, na faʻamaonia ai o mea o loʻo i inei o se polo malosi, o lona uiga o mea iinei o loʻo oomiina.O le pito i tua e malosi e pei o se polo, o le a lava le umi e faʻamaeʻa ai le galuega faʻapipiʻi, o lana galuega lea.
(2) Fa'aaogāina ole fa'apipi'i sikulima ta'itasi
O le extruder tasi-screw e masani ona faʻaaogaina i le faʻaaogaina o paipa, laupepa, papatusi, ma mea faʻasalalau, ma le faʻapipiʻiina o nisi mea faʻaleleia.
(1) Folasaga omea fa'apipi'i fa'amasani
O le twin-screw extruder e aofia ai faiga nei.O le faʻaogaina o le sikulima e faʻamaeʻaina le faʻapipiʻiina ma le tuʻuina atu o meafaitino, lea e iai se aafiaga tele i le faʻatinoga ma le lelei o le oloa maeʻa.
① Faiga fafaga: e aofia ai hopper, afi faʻaoso, ma afi fafaga.E mafai ona taofia le faaputuputuina o meafaitino ma faafaigofie lona ulufale lamolemole i le taulaga fafaga.
② Faiga faʻavevela i fafo: Faʻaaoga masani le faʻavevela ma le paʻu e faʻamafanafana lelei ai mea ma faʻalauteleina le faʻapipiʻiina.
③Faiga malulu: O le faʻaogaina o le vevela e aofia ai le suauʻu vevela poʻo le vai e faʻaaogaina e faʻaitiitia ai le vevela o le fuselage, ina ia mafai ai ona pulea lelei le vevela o le paʻu.
④ Faiga faʻapipiʻi faʻapipiʻi eletise: Faʻaaoga pupuni e mafai ona sui e faʻafefe ai mea leaga, faʻaleleia le tulaga o le palasitika, ma faʻamautinoa le tutusa ma le mautu o le lelei o mea e gaosia.
Fa'ata'ita'iga fa'aoga o le masini fa'apipi'i masaga-screw: faʻamalosia alava tioata, faʻamaʻi afi mumu (e pei o PA6, PA66, PET, PBT, PP, PC faʻamalosia afi mumu, ma isi), faʻapipiʻi maualuga (e pei o le PE, PP faʻatumu i le 75% CaCO3), faʻapipiʻi mea vevela vevela. (e pei o le PVC, XLPE cable material), mafiafia lanu masterbatch (e pei o le faʻatumu o le 50% toner), anti-static masterbatch, alloy, valivali, faʻapipiʻi maualalo faʻafefiloi, faʻapipiʻi mea uaea (E pei o mea faʻapipiʻi, mea faʻapipiʻi), XLPE mea paipa granulation (e pei o le masterbatch mo le vai vevela crosslinking), thermosetting palasitika fefiloi ma extrusion (e pei o le resin phenolic, epoxy resin, paʻu paʻu), faʻapipiʻi faʻafefete vevela, PU faʻafefete faʻapipiʻi faʻapipiʻi (e pei o le EVA vevela faʻafefe, polyurethane), K resin, SBS devolatilization granulation, ma isi.
Fa'ata'ita'iga fa'aoga ole fa'apipi'i sikulima tasi:talafeagai mo PP-R paipa, PE kesi paipa, PEX koluse feso'ota'i paipa, alumini-palasitika tu'ufa'atasi paipa, ABS paipa, PVC paipa, HDPE silicon paipa autu ma eseese co-extruded composite paipa;talafeagai mo PVC, PET, PS, PP, PC ma isi talaaga otooto ma papatusi, ma isi palasitika e pei o filaments, tootoo, ma isi;fetuutuunai le saoasaoa o le extruder ma suia le fausaga o le sikulima extrusion e mafai ona faaaoga i le gaosiga o PVC ma polyolefins.Ma isi fa'amatalaga palasitika.
