Lub luag hauj lwm dab tsi ua Heated Nqus Platens Ua Si hauv Moulding Carbon Fiber Prosthetic Limbs?
Tso lus
Lub qhov (socket) prosthetic yuav tsum ua kom haum rau tib neeg lub cev ntaj ntsug nrog qhov zoo tshaj plaws. Nws yog tsim los ntawm wrapping carbon fiber prepreg nyob ib ncig ntawm ib tug bespoke plaster los yog cov pwm thiab ces kho nws nyob rau hauv ib tug tswj kub thiab nqus ib puag ncig. Lub rhuab platen yog qhov ruaj khov thiab tsis sib xws ntawm lub zog los hloov cov txheej txheem sib xyaw ua ke rau hauv cov qauv nruj thiab lub teeb yuag uas tuaj yeem rov ua haujlwm thiab ua haujlwm.
Kev kho kom raug yog qhov tseem ceeb rau kev ua haujlwm zoo thiab cov neeg mob kev nplij siab hauv kev tsim cov khoom sib xyaw ua ke, thiab lub tshuab nqus tsev vacuum platen prosthetic limb molding thev naus laus zis yog qhov tseem ceeb hauv kev muab cov khoom tsim tau zoo.
Vacuum Forming thiab Composites Consolidation
Lub qhov (socket) feem ntau yog ua los ntawm cov khoom siv fiber ntau hu ua prepregs. Cov no yog carbon fiber reinforcements uas tau ua ntej -impregnated nrog epoxy resin.
Cov txheej txheem ntawm kev tsim khoom yog raws li hauv qab no:
nkhaus pwm nrog txheej txheej carbon fiber layup
Nqus hnab system tsev nyob
Txoj hauj lwm ntawm qhov kub platen nto
Tswj cua sov thiab lub tshuab nqus tsev
Resin kho thiab consolidation ntawm cov khoom sib xyaw
Lub hnab nqus tsev nqus cov cua nkag thiab muab tso rau ntawm lub laminate. Nyob rau tib lub sijhawm, cov rhuab platen muab cov thermal zog xav tau los pib thiab txhawb nqa kev kho ntawm epoxy.
Raws li qhov kub thiab txias nce mus rau qhov zoo li qub ntawm 80-120C, cov resin hloov pauv los ntawm cov kua nplaum mus rau qhov sib txuas ntawm polymer matrix, irreversibly txuas cov txheej ntawm carbon fiber.
Nyob rau hauv ib lub chaw kuaj hniav prosthetics, lub platen yog ib qho mos, rhuab anvil uas pab hloov cov ntaub mos mos rau hauv cov khoom siv kho mob uas muab cov qauv.
Kev ua haujlwm ntawm lub tshuab nqus tsev vacuum
Lub rhuab platen plays ntau lub luag haujlwm tseem ceeb hauv kev tsim cov pob qij txha:
Txawm tias kub rau epoxy kho
Ua haujlwm nrog lub tshuab nqus tsev rau qhov sib faib ntawm lub siab
Tswj qhov seem stability ntawm pwm los ua ke
Txhawb kev tsim khoom rov ua dua tshiab.
Txo lub tshuab nqus tsev tsim hauv cov txheej txheem sib xyaw
Txij li thaum lub qhov (socket) yuav tsum sib haum mus rau tib neeg lub cev thiab lub cev, kev hloov pauv ntawm qhov kub thiab txias thaum lub sijhawm kho yuav ua rau tsis sib xws ntawm cov resin lossis qhov sib txawv hauv zos hauv qhov tawv.
Qhov ib puag ncig kub tsis tu ncua yog qhov tseem ceeb rau cov qauv kev ncaj ncees thiab kev nplij siab ntawm tus neeg mob.
Thaum tshav kub kub hloov thiab tsis sib xws ntawm qhov kub thiab txias
Qhov kub thiab txias faib thoob plaws tag nrho saum npoo ntawm platen nto yuav tsum yog homogeneous heev.
Cov cua sov tsis sib xws tuaj yeem tsim tau:
Kev kho tsis zoo nyob rau hauv cov chaw txias
Kub tsam tshaj kho
Residual nro nyob rau hauv cov khaubncaws sab nraud povtseg
Qhov kawg distortion ntawm lub qhov (socket) geometry
Txhawm rau kom ua tiav cov kev xav tau no, cov tshuab tam sim no feem ntau siv ntau - cheeb tsam cua sov tswj. Txhua cheeb tsam yog tswj hwm tus kheej kom haum rau kev poob ntug thiab qhov sib txawv thermal xav tau.
Kev tswj cov cua sov hauv ib cheeb tsam ua kom muaj kev kho cov kinetics thoob plaws hauv ib feem, vim tias cov pob qij txha feem ntau tsis yog -cov tuab tuab.
Lub npoo du ntawm lub platen paub tseeb geometric raug ntawm hauv qab ntawm cov pwm uas tsim nyog rau kev sib raug zoo thiab lub qhov (socket) haum.
Cov khoom siv thiab cov ntsiab lus thermal teb
Composite prosthesis fabrication yog feem ntau ua nrog rhuab platens ua los ntawm txhuas.
Aluminium raug xaiv vim yog vim li cas
High thermal conduction
Tsawg loj kuj
Ceev thermal teb
Flatness raug zoo machineability
Cov khoom no tso cai rau cov cua kub ceev thiab cua txias, uas yog qhov tseem ceeb rau cov chaw kho mob uas muaj cov khoom siv prosthetic tuaj yeem tsim ua ntu zus.
Aluminium thav duab nrog cov khoom cua sov ua ke tuaj yeem ua kom ruaj khov, tswj kev kho mob thoob plaws ntau lub voj voog ntau lawm.
Thermal Control Interaction nrog lub tshuab nqus tsev
Lub tshuab nqus tsev ua haujlwm ua ke nrog cov rhuab platen kom lav qhov tseeb laminate consolidation.
Lub luag haujlwm tseem ceeb yog:
Displacing cua ntxiab & volatiles
Uniform siab faib thoob plaws cov khoom sib xyaw
Tsis txhob voids nyob rau hauv kho resin
Txhim kho adhesion ntawm fiber ntau rau resin
Cov txheej txheem ruaj khov yog ua kom ntseeg tau los ntawm kev saib xyuas tas li ntawm lub tshuab nqus tsev thaum lub sij hawm kho.
Qhov kub thiab txias profile yog ib txwm ua ua ntej- programmed rau cov kev xav tau ntawm cov khoom tsim cov resin nrog rau cov nqi ramp, lub sij hawm nyob thiab tswj cov theem txias.
Qhov no synergistic tswj ntawm tshav kub thiab lub tshuab nqus tsev guarantees siab zoo composite ntau lawm.
Txheej Txheem Qhia: Direct Temperature Confirmation
Hauv Situ Thermocouple Measurement
Yuav kom tswj tau qhov kub thiab txias, nws yog ib qho tseem ceeb kom nkag siab tias qhov kub ntawm qhov sib xyaw ua ke tsis tas yuav tsum zoo ib yam li qhov ntsuas kub ntsuas los ntawm platen sensors.
Muab ib lub thermocouple ncaj qha rau lossis ze ntawm qhov chaw ntawm lub laminate muaj qhov kev ntsuas kev ntseeg tau ntau dua ntawm qhov ntsuas kub qhov tseeb.
Vim li cas qhov no tseem ceeb?
Lub tshuab nqus tsev cov ntaub ntawv muab thermal kuj.
Resin thiab fiber ntau sib txawv rau cov cua sov dua li cov hlau platens
Cov thermal gradients hauv zos tuaj yeem tshwm sim ntawm feem thiab platen
Kev ntsuas ncaj qha pab kom paub tseeb tias cov kev kho mob raug tswj xyuas nyob rau hauv qhov yuav tsum tau ua siab ntev nyob rau hauv lub voj voog.
Qhov tseem ceeb hauv Prosthetic Fabrication
Thaum tshav kub kub platens nyob rau hauv kev tsim cov pob qij txha prosthetic pub rau uniform creation ntawm:
Qhov (sockets) - qis qis
Prosthetic interfaces rau sab sauv ceg
Orthotic composite designs
Cov khoom siv kho mob tshwj xeeb
Cov txheej txheem cua sov yuav tsum tau rov ua dua rau kev kwv yees kev ua haujlwm zoo, txij li txhua yam khoom siv prosthetic raug kho nyias.
Kev kho tsis sib haum tuaj yeem cuam tshuam:
Sockets Durability
Flexural rigidity
Kev qaug zog
Kev nplij siab thiab haum rau tus neeg mob
Txhim khu kev qha thermal ua tau lees paub tias txhua yam khoom siv prosthetic ua tau raws li cov qauv tsim thiab kev kho mob.
Advanced Thermal Management & Ntau -Zone Control
Cov txheej txheem platen Advanced tau nce ntxiv nrog rau ntau- thaj chaw cua sov thiab kev tswj xyuas kev tawm tswv yim.
uas tso cai:
Kev them nqi hluav taws xob poob ntawm cov npoo
Kev kho kom haum rau ntau yam pwm
Kho qhov kub thiab txias uniformity
tsawg thermal latency nyob rau hauv tuab cheeb tsam ntawm composites
Cov kev tswj xyuas zoo li no txhim kho tag nrho cov kev ruaj ntseg ntawm cov txheej txheem thiab txo qhov unpredictability ntawm tus kheej prosthetic Cheebtsam.
2. Cov lus xaus
Lub tshuab nqus tsev rhuab platen yog ib qho tseem ceeb ntawm kev siv thev naus laus zis hauv kev tsim cov pa roj carbon fiber ntau prosthetics. Qhov kev sib xyaw ua ke ntawm lub tshuab nqus tsev siab thiab tswj tau, homogeneous cua sov ua rau qhov chaw zoo tshaj plaws los kho cov ntaub ntawv epoxy prepreg rau hauv cov khoom siv muaj zog, lub teeb yuag, thiab zoo li cov pob qij txha.
Nyob rau hauv lub rhuab nqus platen prosthetic limb molding txheej txheem, thermal stability thiab uniformity yog qhov tseem ceeb rau cov neeg kho tshuab zoo thiab kev nplij siab ntawm cov khoom kawg. Kev rov ua dua tshiab yog qhov yuav tsum tau muaj nyob rau hauv cov xwm txheej kho mob, thiab kev tsim kho aluminium platen, ntau - thaj chaw cua sov thiab ntsuas kub kom raug txhua qhov kev pab xa tawm.
