Yog vim li cas rau qhov tsim ntawm "adsorbed hais" nyob rau saum npoo ntawm extruded aluminium profiles
Lub ntsiab yog vim li cas rau tsim ntawm "adsorbed hais" yog raws li nram no:
1. Qhov cuam tshuam ntawm pwm
Hauv extrusion ntau lawm, pwm ua haujlwm nyob rau hauv qhov kub thiab txias, ua rau elastic deformation. Kev ua haujlwm ntawm cov pwm pib sib npaug mus rau qhov kev taw qhia extrusion, thiab tom qab raug kev kub ntxhov, cov sawb ua hauj lwm deforms rau hauv ib lub trumpet zoo li tus duab. Tsuas yog cov hniav ib feem ntawm kev ua haujlwm sawb tiv tauj cov txhuas tsim los ntawm qhov profile, zoo ib yam li cov cuab yeej chips ntawm lub cuab yeej tig. Thaum lub sij hawm tsim cov txheej txheem ntawm txhuas adhesion, cov khoom yog tas li nqa tawm los ntawm qhov profile thiab ua raws li qhov chaw ntawm qhov profile, uas ua rau "adsorbed hais".
2. Kev cuam tshuam ntawm cov txheej txheem extrusion
Kev xaiv kom raug ntawm cov txheej txheem extrusion tsis tseem yog qhov tseem ceeb cuam tshuam rau "adsorption ntawm cov khoom". Yog hais tias qhov kub thiab txias extrusion siab dhau lawm thiab qhov extrusion ceev ceev heev, yuav muaj ntau "adsorbed hais". Yog vim li cas yog vim qhov kub thiab txias, qhov khiav ceev ntawm qhov profile nce, qib ntawm pwm deformation nce, ntws ntawm cov hlau nrawm, thiab deformation tsis kam ntawm cov hlau yog qhov tsis muaj zog, ua kom yooj yim rau kev tsim cov khoom. phenomenon ntawm aluminium adhesion.
3. Kev cuam tshuam ntawm Casting Qws Zoo
Qhov zoo ntawm cov pas nrig casting yog qhov tseem ceeb cuam tshuam rau saum npoo thiab extrusion txoj kev ntawm aluminium profiles. Qhov tsim ntawm "adsorbed hais" yog ze ze rau qhov zoo ntawm cov pas nrig casting. Cov yam ntxwv tsis xws luag ntawm cov cam khwb cia muaj xws li slag inclusion, looseness, coarse grain loj, segregation, ci grain loj, thiab lwm yam. Tag nrho cov cam khwb cia pas nrig defects muaj ib tug ntau yam feature, uas yog tsis zoo welding nrog cov cam khwb cia pas nrig substrate, uas ua rau discontinuous ntws. ntawm lub substrate, uas yog ib qho tseem ceeb nyob rau hauv tsim ntawm "adsorbed hais".
Lub ntsiab cuam tshuam ntawm "cov khoom adsorbed" yog pwm, casting pas nrig, thiab txheej txheem extrusion. Qib kev ua haujlwm ntawm cov neeg ua haujlwm kuj tseem cuam tshuam hauv peb lub ntsiab lus. Raws li kev xyaum ua ntau lawm, kev soj ntsuam tas li ntawm cov teeb meem thiab cov ntsiab lus ntawm cov kev paub dhau los tuaj yeem txo lossis zam "cov khoom adsorbed", zoo heev txhim kho cov txiaj ntsig thiab kev tsim khoom ntawm cov profiles.
