Peb -txheej txheej co-extrusion tshuab tshuab yog ib qho khoom siv ua yeeb yaj kiab siab heev. Nws muaj qhov zoo hauv qab no: Ntau- txheej txheej txheej zoo: los ntawm peb- txheej co-extrusion tshuab, cov khoom sib txawv ntawm cov ntaub ntawv tuaj yeem ua ke kom ua tiav cov khoom siv yeeb yaj kiab multifunctional. Piv txwv li, txheej txheej sab nrauv muaj huab cua tsis zoo thiab luam ntawv, txheej nruab nrab lav lub zog thiab cov khoom thaiv, thiab cov txheej sab hauv ua tau raws li qhov yuav tsum tau ua kom sov.
Dab tsi ntawm kev tuag yog siv nyob rau hauv peb- txheej co-extrusion tshuab tshuab?
Qhov tuag ntawm peb - txheej co- extrusion tshuab tshuab muaj xws li cov hauv qab no:
Planar stacking pwm: Melt flows symmetrically raws lub hauv paus axis ntawm txhua txheej ntawm stacking nto piv rau cov tsoos cylindrical ntws. Qhov zoo yog tias cov txheej txheem tuag tuaj yeem ua ke arbitrarily, cov qauv yooj yim thiab qhov kub ntawm txhua txheej tuaj yeem tswj tau ntawm nws tus kheej.
Conical stacked tuag: ib tug modular conical qauv, txhua chav tsev muaj ib tug ob peb luv luv conical modules, ntws txoj kev ntawm lub conical cylindrical nto. Cov pwm no tau muab faib ua ob hom: pawg nce toj thiab nqes toj. Lub sab sauv conical stacking pwm feem ntau yog siv rau pwm nrog txoj kab uas hla ntawm 10mm-50mm, thaum lub downward- sloping conical stacked hom yog haum rau loj co-extrusion tuag.
Radial stacking tuag: txoj kev khiav yog helical mandrel, qhov chaw nruab nrab yog qis, qhov siab tuag tsis nce nrog cov txheej txheem. Txij li thaum lub siab yaj yog sib npaug raws li cov kev taw qhia ncig ntawm cov dej ntws, qhov kev sib khi ua tau zoo dua li hom stacking. Txawm li cas los xij, qhov tsis zoo yog qhov kub yaj, tshwj xeeb tshaj yog nyob rau hauv nruab nrab txheej, tsis tuaj yeem tswj nws tus kheej.
Peb - txheej co-extrusion tshuab tshuab yog siv dav: cov yeeb yaj kiab tuaj yeem siv ntau yam xws li ntim khoom noj, ntim khoom thiab ntim khoom lag luam, thiab ua tau raws li cov kev xav tau ntawm kev lag luam sib txawv. Kev tsim khoom muaj txiaj ntsig: kev ua haujlwm siab ntau lawm, tuaj yeem ua tau sai sai ntawm cov yeeb yaj kiab ua raws ntau. Kev siv thev naus laus zis: kev siv lub tshuab computer tsis siv neeg tswj thiab lwm yam kev tswj hwm qib siab los pab txhawb kev lag luam thiab saib xyuas tag nrho cov txheej txheem tsim khoom.
Structurally, nws tsuas yog muaj xws li ib tug extrusion system, pwm, cua nplhaib, traction ntaus ntawv thiab winding ntaus ntawv. Lub extrusion system heats, melts thiab extrudes cov khoom yas sib txawv; lub taub hau tuag ua rau cov khoom siv extruded los ua tubular zaj duab xis npuas; lub nplhaib cua yog siv los ua kom txias thiab tswj cov npuas npuas; thiab cov cuab yeej traction stretches daim nyias nyias thiab coj nws mus rau lub tshuab winding.
