Sib tham txog lub luag haujlwm ntawm tus ciav hlau extruder

Qhov zoo ntawm cov ntswj extruder
Cov khoom siv ntawm tus ciav hlau extruder yuav tsum muaj qhov sib zog ua muaj zog, yuav muaj peev xwm tiv tau cov torques loj thiab muaj cov cuab yeej ntawm tsis deforming hauv kub thiab siab siab.
Qhov laj thawj yog: txoj kev sib hloov ntawm cov thawv tawm extruder hauv lub thoob yog ua tiav hauv kev kub siab, kev kub siab thiab siab torque. Vim tias nws xav thawb cov khoom rau pem hauv ntej thaum lub sij hawm kev sib hloov, nws kuj tau muaj kev sib zog ua ke muaj zog txhuam thiab yas corrosion. Gas yaig, yog li cov nqus hlau extruder yuav tsum muaj cov kev zoo no.
Cov teeb meem uas muaj teeb meem nrog kev sib tw extruder
Thaum lub voj voog extruder, lub plag feem ntau yog sheared thiab yas los ntawm txoj hlua hau, thiab cov yas yuav raug thawb rau pem hauv ntej, kom lub kauj vab ntug yuav dais loj thiab kev sib txeeb.
Vim yog lub sijhawm ua haujlwm tsis zoo rau cov neeg mob, cov ribs hnav, ribs ua me dua, thiab qhov kis tau nrog cov thawv nce, uas ua rau txo tus nqi ntawm cov yas extrusion. Nyob rau hauv loj heev zaum, yas reflow tshwm sim, thiab cov nyom plasticising txo, thiab siv lead ua los tshwm. Thiab qhov phenomenon ntawm loj poob nyob rau hauv qhuav peev xwm.
Kwv yees ua tus txheej txheem ntawm yaj ntoos extrusion
Cov txheej txheem ntawm yaj extrusion yog los noj cov khoom siv ua ntej los ntawm qhov chaw nres nkoj pub rau hauv cov thawv tawm sab nrauv los ntawm thawj seem ntawm lub thoob raws li qhov chaw pub mis. Cov khoom yuav tsis yaj ntawm theem no, tab sis yuav tau tsav los ntawm lub hau ntswj ntawm extruder; Qhov thib ob theem yog qhov seem compression. Cov theem yog cua kub theem, cov khoom pib yaj, thiab cov kev sib txhuam ntawm cov ntaub ntawv nce mus ua ib tug high-viscosity. Tshooj thib peb uas tseem tsav tsheb nrog tus ntsia hlau ntawm lub extruder rau hauv high shear yog homogenization seem. Cov theem no ua rau nws zoo heev hauv kev sib cais pigment aggregates rau lub hom phiaj ntawm tag nrho dispersion.
Qhov zoo tshaj ntawm extruder ncaj qha txiav txim cov degree ntawm dispersion ntawm cov khoom.
Tam sim no, extruder khoom siv nyob rau hauv cov hmoov coatings yog ib tug twin extruder ntsia hlau extruder, ib extruder ntsia hlau extruder thiab ib lub hnub qub extruder ntsia hlau extruder, thiab lwm yam, txawm tias hom extruder, Internal tsim yog txawv, tab sis tus tsim yog zoo ib yam, uas yog, kom tsis txhob muaj teeb meem ntawm cov khoom siv.
