Yini izinga lokushisa elifanelekile lokushaya imikhiqizo ebunjiwe

Uhla lokushisa olufanele lweBlow imikhiqizo ebunjiweimvamisa phakathi kuka-180 ℃ no-220 ℃. Ngaphakathi kwaleli banga lokushisa, ipulasitiki ingancibilika ngokuphelele, ihlenge kahle, yenza lula ukubumba okushaya ngamandla, futhi igweme ukwanda ngokweqile kwepulasitiki ukukhiqiza ama-bubble, ngaleyo ndlela kuqinisekiswe ukuhlanganiswa namandla omkhiqizo. ‌

Izidingo zokushisa kwezinto ezahlukahlukene nemikhiqizo

HDPE: izinga lokushisa leBlow Ukuhlanganisa UmshiniNgokuvamile isethwe phakathi kuka-170-210 ℃, futhi amapharamitha athile okushisa adinga ukulungiswa ngokuya ngosayizi womkhiqizo. Imikhiqizo emincane inamazinga okushisa aphansi, ngenkathi imikhiqizo emikhulu idinga amazinga okushisa aphezulu. Izinga lokushisa eliphansi lingadala ukuqhuma kwemibungu, ngenkathi izinga lokushisa eliphakeme lingaholela ekulinganiseni udonga olungalingani lomkhiqizo.

Izinto ze-TPV: Amazinga okushisa anconyiwe ngaphambi kokuqunjelwa kokubumba ngu-170 ± 10 ℃, kanti izinga lokushisa elibumba livame ukunconywa ukuba ngaphansi kwama-40 ℃. Ukwehlisa izinga lokushisa okulonda kusiza ngokubumba umkhiqizo kanye nesivinini esidonsayo, kepha kungathinta ukubukeka namandla omkhiqizo.

Ithonya lokushisa kukhwalithi yokubumba okushayayo

Izinga lokushisa eliphansi: Kungadala ukuthi ipulasitiki lingancibiliki ngokuphelele, lithinta ikhwalithi yokubumba okushayayo, okuholela ekulimaleni komhlaba futhi kuncishiswe ama-aesthetics nokusebenza.

Ukushisa okuphezulu: Kungadala ukuncibilika ngokweqile nokwanda kwepulasitiki, okungakha kalula ama-bubble ngaphakathi komkhiqizo, okuthinta izakhiwo zayo zemishini nokuqina. Ngaphezu kwalokho, amazinga okushisa aphezulu nawo angadala ukubola, ukukhiqiza amagesi ayingozi okusongela impilo yabantu nasendaweni yemvelo.

Izinyathelo eziqondile zokulawulwa kokushisa

Ukomisa ngokwezinto ezibonakalayo: Ngaphambi kokushaya ngamandla, qiniseka ukuthi lokho kumiswa ngokuphelele ukugwema izimbobo zomoya noma amabala enkungu angathinta ukucaca komkhiqizo wokugcina wokubumba.

Ukushisa okushisa kwe-billet: izinga lokushisa lokushisa le-billet lidinga ukulawulwa ngokuqinile. Uma kuphezulu kakhulu, i-viscosity yezinto ezincibilikisiwe izokwehla futhi kulula ukuzilimaza. Uma kuphansi kakhulu, izoqongelela ingcindezi yangaphakathi yangaphakathi ngaphakathi komkhiqizo, okuthambekele ekucindezelekeni kokuqhekeka ngesikhathi sokusetshenziswa.
