Mapangidwe a screw angaphatikizeponso zinthu zosiyanasiyana monga magawo osakanikirana, ma grooves, kapena zotchingira zotchingira kuti zisungunuke ndi kusakanikirana bwino.Zinthuzi zimathandiza kukwaniritsa kugawidwa kofanana kwa pulasitiki yosungunuka ndikuwonetsetsa kuti zigawo zomwe zimapangidwira zimakhala zogwirizana.
Chophimba chowomba mbiya ndi nyumba ya cylindrical yomwe imatsekera screw.Amapereka kutentha kofunikira ndi kukakamizidwa kofunikira kuti asungunuke zinthu zapulasitiki.Mgolowu nthawi zambiri umagawidwa m'magawo angapo otenthetsera ndikuwongolera kutentha kwamunthu payekha kuti akwaniritse kusungunuka koyenera komanso kukhazikika kwa pulasitiki.
Screw Design: Zomangira zomwe zimagwiritsidwa ntchito m'makina omangira zida zidapangidwa kuti zithandizire kusungunula ndi kukonza homogenization.Nthawi zambiri imakhala yayitali poyerekeza ndi zomangira zomwe zimagwiritsidwa ntchito munjira zina zamapulasitiki.Kutalika kwautali kumapangitsa kuti pulasitiki ikhale yabwino komanso kusakaniza pulasitiki yosungunuka.Zomangirazo zimathanso kukhala ndi magawo osiyanasiyana, monga chakudya, kuponderezana, ndi ma metering zone, kuti azitha kuyendetsa komanso kuthamanga kwa pulasitiki yosungunuka.
Mapangidwe a Mitsuko: Mgolo umapereka kutentha kofunikira ndi kukakamizidwa kofunikira kusungunula zinthu zapulasitiki.Nthawi zambiri imakhala ndi magawo angapo otenthetsera omwe amayendetsedwa ndi ma heater ndi masensa otentha.Mgolowu nthawi zambiri umapangidwa kuchokera ku zinthu zapamwamba kwambiri, monga chitsulo chopangidwa ndi nitride kapena ma alloys a bimetallic, kuti athe kupirira kutentha kwambiri komanso kuvala chifukwa cha pulasitiki ndi screw.
Kuchiza Pamwamba: Kuti azitha kupirira komanso kulimba kwa screw ndi mbiya, amatha kulandira chithandizo chapamwamba monga nitriding, hard chrome plating, kapena zokutira zachitsulo.Mankhwalawa amawonjezera mphamvu ndi kukana kuvala, kuonetsetsa kuti zinthuzo zikhale ndi moyo wautali.
Zonse ziwiri zomangira ndi mbiya nthawi zambiri zimapangidwa kuchokera ku zinthu zomwe zimavala kwambiri komanso kukana dzimbiri, monga chitsulo chothiridwa ndi nitride kapena ma aloyi a bimetallic.Zidazi zimatsimikizira moyo wautali komanso kugwira ntchito, ngakhale pokonza mapulasitiki owononga kapena owononga.
Kuyeretsa ndi Kusamalira: Kusamalira bwino ndi kuyeretsa wononga ndi mbiya ndikofunikira kuti zitsimikizire kuti zikuyenda bwino komanso kuti zinthu zili bwino.Kuyeretsa nthawi zonse kumathandiza kupewa kuchulukana kwa zotsalira kapena zonyansa zomwe zingakhudze kusungunuka ndi kuumba.Njira zosiyanasiyana zoyeretsera, monga kuyeretsa pamakina, kuthira mankhwala, kapena kutsuka ndi mankhwala oyeretsera, angagwiritsidwe ntchito.
Mwachidule, zomangira zowomba ndi mbiya ndizofunikira kwambiri pakuumba nkhonya.Amagwirira ntchito limodzi kusungunula, kusakaniza, ndi kupanga homogenize zinthu zapulasitiki, kulola kupanga bwino magawo apulasitiki opanda kanthu.Kusamalira moyenera ndi kuyeretsa zigawozi ndizofunikira kwambiri kuti zitsimikizire kuti zikuyenda bwino komanso kuti zinthu zili bwino.
