Chiyambi cha mphira wotulutsa ndi mtundu wa extruder

Chiyambi cha chotulutsira mphira

Chotulutsira rabara ndi chida chofunikira kwambiri mumakampani opanga rabara ndipo ndi chimodzi mwa zida zofunika kwambiri zomwe zimakhudza mtundu wa malonda. Chimagwira ntchito yofunika kwambiri popanga matayala ndi zinthu za rabara. Kupanga kwa zotulutsira rabara zakunja kwakhala ndi Plug extruder, screw type hot feed extruder, common cold feed extruder, main and assistant screw thread cold extruder, cold feed exhaust extruder, pin cold feed extruder, Compound extruder ndi magawo ena. Chotulutsira rabara chimagwiritsidwa ntchito pokanikiza, kusefa ndi kuphimba zinthu za rabara. Kapangidwe kake: Chokuluzira ndi chikwama chamkati zimapangidwa ndi chitsulo cha nitrided, chomwe chimakhala ndi kukana kwabwino kwa kuwonongeka komanso kukana dzimbiri.

Kutulutsa screw kwa rabara pogwiritsa ntchito chotulutsira rabara ndi imodzi mwa madera akale kwambiri aukadaulo wotulutsa, womwe ukhoza kutsatiridwa kuyambira m'zaka za m'ma 1800. Zotulutsira rabara zimasiyana kwambiri ndi zotulutsira thermoplastic. Choyamba, kutulutsa rabara kumachitika kutentha kotsika (mpaka 130°C). Chachiwiri, kutulutsa rabara nthawi zambiri kumaphatikizapo zingwe (ndipo nthawi zina, ma pellets), zomwe sizimasintha gawo mkati mwa dongosolo la screw extruder kapena kukhuthala kwakukulu. Mosiyana ndi thermoplastics, thermoplastics imakonzedwa kutentha kwa 180^-300 °C (kapena kupitirira apo) mu screw extruder, ndipo tinthu tating'onoting'ono tomwe timakhala tolimba nthawi zambiri timawonjezeredwa ku extruder. Pamene ma pellets akupita patsogolo motsatira screw, chitsime chosungunuka chimapindika.

Zipangizo zotulutsira mphira nthawi zambiri zimagawidwa m'magulu a makina odyetsera otentha ndi makina ozizira. Muzipangizo zotulutsira mphira zotentha, rabara imatenthedwa ndi makina otseguka, ndipo timizere totenthetsera timadulidwa ndikutulutsidwa mosalekeza. Kudyetsa kuchokera ku makina. Muzipangizo zotulutsira mphira zozizira, mzere wa rabara wotentha m'chipinda umawonjezeredwa ku chipangizo chotulutsira mphira. Chotulutsira mphira nthawi zambiri chimagawidwa malinga ndi ngati chimagwiritsidwa ntchito potulutsa utsi kapena ayi.

Mitundu ya Zotulutsa Mphira

Chotulutsira rabara ndi chida chofunikira kwambiri mumakampani opanga rabara ndipo ndi chimodzi mwa zida zofunika kwambiri zomwe zimakhudza mtundu wa malonda. Chimagwira ntchito yofunika kwambiri popanga matayala ndi zinthu za rabara. Kupanga kwa zotulutsira rabara zakunja kwadutsa column Plug extruder, screw type hot feed extruder, common cold feed extruder, main and assistant screw thread cold extruder, cold feed exhaust extruder, pin cold feed extruder, Compound extruder ndi magawo ena.

Chotulutsira rabara chimagawidwa m'magulu awa: mtundu wa plunger, mtundu wa screw, mtundu wamba, mtundu wodyetsa ozizira, mtundu wa pini, mtundu wa compound. Kukula kwamtsogolo: ukadaulo wolondola wamakina owongolera ma drive okhala ndi ma screw ambiri
