Tshiab 3D luam ntawv thev naus laus zis tau tsim los ntawm qhov nrawm nrawm uas nws yooj yim rau kev xav txog yav tom ntej nyob ze uas tsis muaj dab tsi uas tsis tuaj yeem luam tawm 3D.
Qhov ntau ntawm cov ntaub ntawv muaj yog ib qho ntawm cov teeb meem tseem ceeb rau kev saws me nyuam rau kev lag luam 3D luam ntawv.3D luam ntawv tau txais sai sai los ntawm cov khoom lag luam thoob plaws ntiaj teb, tab sis nws tseem tsis tuaj yeem sib tw nrog ntau lwm cov txheej txheem tsim khoom nrog rau kev sib txawv ntawm cov khoom siv.Ib tug loj tus naj npawb ntawm cov feem ntau siv industrial plastics tseem tsis dav muaj rau 3D tshuab luam ntawv, ua 3D luam ntawv tsis haum rau ntau daim ntawv thov.
PTFE (polytetrafluoroethylene) yog ib qho khoom siv zoo heev, siv ntau yam khoom siv niaj hnub.Nws yog hydrophobic heev, txhais tau hais tias tsis yog dej los yog dej uas muaj cov khoom ua rau nws ntub, yog li nws yog siv rau hauv cov khaub ncaws sab nraum zoov.Nws kuj muaj ib qho kev sib txhuam coefficients qis tshaj ntawm cov khoom.Nws tsuas yog qhov chaw uas gecko tsis tuaj yeem lo rau.Cov cuab yeej no ua rau nws zoo meej rau cov txheej txheem tsis yog lo rau bakeware.Cov kab mob thiab lwm yam microbes kuj muaj lub sijhawm nyuaj heev rau kev ua raws li cov khoom siv, ua rau nws yog qhov kev xaiv zoo heev rau ntau yam kev siv hauv tsev kho mob, xws li catheters.
Lwm cov fluoropolymer kuj tseem siv ntau hauv cov roj thiab roj, tshuaj lom neeg, tsheb thiab aerospace kev lag luam, thiab nws muaj peev xwm hais tias tib 3D tshuab luam ntawv tuaj yeem siv rau lawv.Qhov kev tawg no ua rau nws ua tau rau 3D luam tawm tag nrho cov ntaub ntawv tshiab, uas yuav cuam tshuam rau ntau qhov kev lag luam.
Nquag, qhov chaw ua los ntawm PTFE thiab lwm yam fluoropolymer yog tsim los siv cov txheej txheem kim kim, uas feem ntau tsim cov khib nyiab ntau.Nws kuj yog ib qho nyuaj rau tsim cov qauv complex.3D luam ntawvmuaj lub peev xwm los muab kev tsim khoom ruaj khov thiab muaj ntau yam qauv tsim.Txoj kev tawg yog twb paving txoj kev rau yav dhau los daim ntawv thov tsis yooj yim sua.
Fluorinated polymers, aka fluoropolymers, tej zaum yuav tsis zoo li lub pob zeb diamond, tab sis lawv yog cov khoom siv tseem ceeb hauv ntau cov txheej txheem tsim khoom.Cov fluorocarbon-based plastics yog qhov txawv los ntawm lawv cov kev ua haujlwm siab thiab ua haujlwm rau cov tshuaj hnyav thiab kub siab.Siv nyob rau hauv txhua yam los ntawm aerospace thiab kev tiv thaiv daim ntawv thov mus rau qhov chaw uas tsis yog-stick ua noj, fluoropolymer nyob txhua qhov chaw - tshwj tsis yog rau hauv 3D tshuab luam ntawv.
Qhov ntawd yuav hloov sai sai, txawm li cas los xij, raws li cov tuam txhab tsim khoom lag luam 3M tau ua daim ntawv patent rau hom tshiab 3D luam ntawv thev naus laus zis uas yuav tso cai rau kev tsim khoom ntxiv ntawm cov fluorinated polymers.Cov thev naus laus zis yuav txhais tau tias cov txheej txheem nyuaj tuaj yeem tsim tau sai thiab pheej yig, whereas tib qhov chaw feem ntau yuav txwv tsis pub kim los tsim nrog lwm cov txheej txheem tsim khoom.
Thaum muaj ntau yam ntawm fluorinated polymers, tej zaum ib qho uas yuav tau txais txiaj ntsig zoo tshaj plaws los ntawm 3D luam ntawv yog polytetrafluoroethylene lossis PTFE, feem ntau hu ua polymer.PTFE, uas nquag siv rau hauv daim ntawv thov xws li kev sib khi thiab hauv ob sab phlu, tsim cov khoom pov tseg ntau hauv ntau lawm.3D luam ntawv nws - uas 3M yuav yog thawj zaug ua - yuav txo qis ntawm qhov pov tseg ntawd.Tsis tas li ntawd, cov tuam txhab uas siv qhov zoo ntawm cov txheej txheem yuav tuaj yeem tsim cov txheej txheem nyuaj, ntau cov khoom siv polymer hauv ib thooj es tsis yog yuav tsum tau pwm thiab sib sau ua ke ntau yam.
