Kev xaiv ntawm cov ntsia hlau qauv ntawm cov yas extruder yog tsuas yog txiav txim siab raws li lub cev lub zog ntawm cov yas thiab cov khoom specifications ntawm lub extruder.
1.Lub softening ntawm amorphous compound yog ua tiav nyob rau hauv ib tug kuj dav kub. Feem ntau, isometric gradual ntsia hlau yog siv.Lub melting kub ntau yam ntawm crystalline polymers yog nqaim, thiab isometric abrupt screws feem ntau yog siv.
2.Ntawm cov yas me me rctruders, xws li p45 extruder, cov ntsia hlau txais ib hom threaded tag nrho nrog sib npaug sib npaug thiab qhov tob tsis sib npaug.Qhov ntev ntawm cov ntsia hlau yog me me, thiab nws yog tsuas yog siv rau extruding me me cross-section rwb thaiv tsev thiab sheath. khaubncaws sab nraud povtseg.Qhov extrusion ceev yog ceev.
3.Cov ntsia hlau nruab nrab siv cov xov xov tag nrho nrog qhov sib npaug thiab maj mam sib sib zog nqus qhov tob.Nws qhov ntev-rau-qhov sib piv yog loj dua ntawm cov ntsia hlau me me, thiab lub suab ntawm cov xov yog sib npaug, pib ntawm lub hauv paus los ntawm ntiav. mus tob.Cov xov ntawm qhov kawg ntawm cov xov yog ntxaum thiab cov xov ntawm lub hauv paus yog ahallow.Qhov no, tus nqi ntawm cov yas extrusion yog ntau, tab sis tsis.
Muaj feem xyuam rau lub zog ntawm cov ntsia hlau, lub extrusion ceev ceev, thiab cov yas yog zoo plasticized.Nws yog ib qho zoo tagnrho ntsia hlau rau zus tau tej cov insulating thiab sheath txheej ntawm dav me me thiab nruab nrab extruders.
