The guda dunƙule extruder ne yafi amfani a extrusion na bututu, zanen gado, faranti, da profiled kayan, da granulation na wasu modified kayan.
(1) Gabatarwatwin-screw extruder
Twin-screw extruder ya haɗa da tsarin masu zuwa. Tsarin dunƙule galibi yana kammala aikin filastik da isar da kayan aiki, wanda ke da babban tasiri akan aiki da ingancin samfuran da aka gama.
① Tsarin ciyarwa: gami da hopper, motsa jiki, da injin ciyarwa. Zai iya hana tarin kayan abu kuma ya sauƙaƙe shigarsa cikin santsi cikin tashar abinci.
② Tsarin dumama na waje: Yawanci amfani da sandar dumama da Silinda don dumama kayan da kyau da kuma inganta aikin filastik.
③Tsarin sanyaya: Ana amfani da tsarin musayar zafi wanda ya ƙunshi mai ko ruwa don rage zafi na fuselage, don sarrafa yanayin zafin silinda yadda ya kamata.
④ Tsarin canza allo na hydraulic: Yi amfani da allon tace mai maye gurbin don tsangwama da ƙazanta, haɓaka matakin filastik, da tabbatar da daidaito da kwanciyar hankali na ingancin kayan fitarwa.
Misalin aikace-aikace na twin-screw extruder: gilashin fiber ƙarfafa, granulation na harshen wuta (kamar PA6, PA66, PET, PBT, PP, PC ƙarfafa harshen wuta, da dai sauransu), babban filler granulation (kamar PE, PP cike da 75% CaCO3), zafi-m abu granulation. (kamar PVC, XLPE na USB material), kauri mai launi masterbatch (kamar cika 50% toner), anti-static masterbatch, gami, canza launi, ƙaramin cika cakuda granulation, granulation na USB (Kamar kayan sheath, kayan insulating), XLPE bututu abu granulation (kamar masterbatch ga ruwan zafi crosslinking), thermosetting filastik hadawa da extrusion (kamar phenolic guduro, epoxy guduro, foda shafi), zafi narke m, PU amsa extrusion granulation (kamar EVA zafi narke m, polyurethane), K guduro, SBS delatilization granulation, da dai sauransu.
