Nkhani Zamakampani

Kusakaniza kogawa kumafalikira zigawo kudzera mu sungunula; dispersive kusanganikirana yopuma agglomerates kapena amachepetsa kukula kwa omwazika gawo. Kapangidwe kawiri kawiri kaŵirikaŵiri kumafunika zonse ziwiri, koma mlingo uyenera kutsata chilema ndi mapangidwe m'malo mokonda kukameta ubweya wambiri. Choyamba zindikirani vuto, kenako yerekezerani khalidwe losakaniza mkati mwa malire a kutentha ndi makina a mzere.

Sankhani conical twin screw extruder kapena parallel twin screw extruder molingana ndi mawonekedwe a PVC, zenera lofunikira ndi kasinthidwe ka makina, osati zilembo za geometry zokha. Fananizani ntchito zofananira, kenako yang'anani zomwe zavomerezedwa, mtundu wazinthu, kugwiritsa ntchito mphamvu ndi kugwirizanitsa kwamakina. Pa mzere womwe ulipo, sankhani ngati mukufuna zida zosinthira kapena makina ena omanga musanapemphe mawu.

Extruder screw pitch ndi malo axial pakati pa ndege zoyandikana; kutsogola ndiko kutsogola kwa axial kwa helix yomweyi kudzera munjira imodzi yathunthu. Ndiofanana pagawo loyambira limodzi, koma osati pa screw iliyonse. Sankhani kusintha kwa lead potengera kudyetsa, kusungunula ndi kutulutsa mphamvu, m'malo mongoganiza kuti kusiyanitsidwa kwakukulu kumatsimikizira kutulutsa kwabwino.

Kuzama kwa njira ya Extruder screw kumatanthawuza danga lomwe lili pakati pa screw root ndi zofotokozera zakunja. Njira yozama imapereka malo ochulukirapo, koma sikuti imangopereka zotulutsa zabwino zambiri motsutsana ndi kufa. Sankhani mbiriyo ndi ntchito zake zodyetsera, kusungunula ndi kupopera, ndi miyeso yeniyeni, zakuthupi ndi mbiya yofananira zomwe zafotokozedwa.

Single wononga extruder L/D chiŵerengero ndi otchulidwa ntchito kutalika kugawidwa ndi mwadzina wononga wononga awiri. Sankhani potengera malo ofunikira kuti mudyetse, kusungunula, kusakaniza, kutulutsa mpweya ndi kukulitsa kupanikizika, osati kungoganiza kuti screw yautali imapereka zotulutsa zambiri. Tsimikizirani kuchuluka kwa miyeso ndi kaphatikizidwe ka makina musanafanizire mawu.

Extrusion screw compression ratio imafotokoza kuchepetsedwa kwa voliyumu ya tchanelo kuchokera ku chakudya kupita ku mita; kwa zomangira wamba zokhala ndi lead yofanana m'magawo onse awiri, zimawonetsedwa ngati kuya kwa ngalande yogawidwa ndi kuya kwa tchanelo. Sankhani ndi kuya kwenikweni, kutalika kwa kusintha, feedstock ndi kapangidwe ka migolo, osati kuchokera ku dzina la polima lokha. Chiŵerengero chapamwamba sichimangokhala wononga bwino.
