Taw qhia ntawm 3D tshuab luam ntawv
3D tshuab luam ntawv moulding tshuab yog ib hom kev tsim khoom sai sai thiab kev tsim khoom ntxiv.Nws yog txheej txheem ntawm kev sib txuas lossis kho cov ntaub ntawv los tsim cov khoom peb sab hauv kev tswj hwm lub computer.Feem ntau, kua molecules los yog hmoov hais yog fused ua ke thiab sib sau txheej los ntawm txheej thaum kawg tsim cov khoom..Tam sim no, 3D luam ntawv thiab molding technologies feem ntau muaj xws li: fused deposition txoj kev, xws li kev siv cov thermoplastics, eutectic system hlau cov ntaub ntawv, nws molding ceev yog qeeb, thiab fluidity ntawm cov khoom molten yog zoo dua;
Txawm li cas los xij, PTFE raj muaj txoj haujlwm tseem ceeb hauv 3D tshuab luam ntawv.3D tshuab luam ntawv yog inseparable ntawm PTFE raj.Ua cas koj ho hais li ntawd?Tom ntej no, lub tuam txhab Besteflon yuav piav qhia rau koj vim li cas 3D tshuab luam ntawv tsis tuaj yeem ua yam tsis muaj PTFE raj.
Nyob rau hauv 2015, lub npe nrov 3D tshuab luam ntawv chaw tsim tshuaj paus Airwolf tso nws thawj pej xeem-theem 3D tshuab luam ntawv.PTFE raj yog siv nyob rau hauv ntau yam tseem ceeb.Vim tias cov ntaub ntawv qib engineering xav tau qhov kub thiab txias tas li, cov kev xav tau ntawm cov khoom siv yog siab heev.Yog li ntawd, lub tshuab luam ntawv 3D siv lub raj PTFE raws li lub raj feeder, thiab ib qho kev sib cais nruab nrab yog ntxiv ntawm PTFE raj thiab lub rhaub.Thaum siv lub tshuab luam ntawv 3d, cov filament yog siv rau kev luam ntawv.Lub filament yog nyob rau ntawm ib lub reel, yog li nws tuaj yeem yooj yim unrolled kom lub tshuab luam ntawv 3D tuaj yeem yob cov ntaub ntawv yooj yim.Lub filament txuas los ntawm lub reel los ntawm PTFE hose mus rau lub taub hau luam ntawv.Lub PTFE raj ua kom ntseeg tau tias cov filament yuav tsis ntsib teeb meem ntawm txoj kev, yog coj mus rau qhov tseeb, thiab yuav tsis puas los yog poob zoo ntawm txoj kev mus rau lub 3D luam ntawv lub taub hau.Tom qab tag nrho, koj xav kom muaj peev xwm muab cov filaments zoo rau 3D printheads.Lub luag haujlwm ntawm3D tshuab luam ntawv nrog PTFE rajyog li ntawd tseem ceeb heev
Dab tsi yog cov yam ntxwv ntawm PTFE raj
1. Tsis-nplaum: PTFE yog inert, yuav luag tag nrho cov ntaub ntawv tsis sib txuas nrog cov hlab, thiab cov yeeb yaj kiab nyias kuj qhia cov khoom tsis-stick.
2. Kub thiab txias tsis kam:PTFE tubesmuaj kub zoo heev thiab tsis kub tsis kam.Nyob rau hauv ib lub sij hawm luv luv, nws tuaj yeem tiv taus kub txog 300℃, melting point yog 327℃, thiab nws yuav tsis yaj ntawm 380℃.Feem ntau, nws tuaj yeem siv tsis tu ncua ntawm 240℃thiab 260℃.Nws muaj qhov zoo tshaj plaws thermal stability.Nws tuaj yeem ua haujlwm ntawm qhov kub thiab txias.Tsis muaj embrittlement, txias tsis kam mus rau 190℃.
3. Lubricity: PTFE raj muaj qhov coefficient ntawm kev sib txhuam.Kev sib txhuam coefficient hloov thaum lub load yog zawv zawg, tab sis tus nqi tsuas yog nyob nruab nrab ntawm 0.04-0.15.
4. Tsis-hygroscopicity: Qhov saum npoo ntawm PTFE raj tsis lo rau dej thiab roj, thiab nws tsis yooj yim rau lo rau cov tshuaj thaum lub sijhawm ua haujlwm ntau lawm.Yog tias muaj cov av me me, nws tuaj yeem raug tshem tawm los ntawm kev so yooj yim.Lub sijhawm luv luv, txuag sijhawm ua haujlwm thiab txhim kho kev ua haujlwm zoo.
5. Corrosion resistance: PTFE hose tsis tshua muaj corroded los ntawm cov tshuaj, thiab tuaj yeem tiv taus tag nrho cov acids muaj zog (xws li aqua regia), muaj zog alkalis, thiab cov kua qaub muaj zog tshwj tsis yog cov hlau alkali hlau, fluorinated media, thiab sodium hydroxide saum 300.°C. Lub luag haujlwm ntawm oxidants, txo cov neeg ua haujlwm thiab ntau cov kuab tshuaj organic tuaj yeem tiv thaiv qhov chaw ntawm txhua yam tshuaj lom neeg corrosion.
6. Huab cua tsis kam: tsis muaj kev laus, zoo dua lub neej tsis zoo hauv cov yas.
7. Tsis muaj tshuaj lom: Hauv ib puag ncig ib puag ncig tsis pub dhau 300℃, nws yog physiologically inert, non-toxic thiab yuav siv tau raws li kev kho mob thiab khoom noj khoom haus khoom
Thaum twg los hloov lub raj filament ntawm lub tshuab luam ntawv 3D
Yog tias koj cov hlua khi los yog daig hauv lub raj filament lossis PTFE raj, koj yuav tsum hloov lub tshuab luam ntawv 3D PTFE raj.Cov hlab ntsha tawg yuav cuam tshuam rau cov txiaj ntsig luam ntawv.Qhov no yog qhov txaj muag, vim qee zaum, koj tuaj yeem rov pib luam ntawv.Qee tus neeg txawm xav tias yog tias cov filament tau daig hauv lub raj, lub tshuab luam ntawv 3D yuav puas.Nws yog tsis yooj yim sua rau lub tshuab luam ntawv los tuav lub filament, uas yuav ua rau tsis xws luag thiab lwm yam kev puas tsuaj.Nws raug pom zoo kom tiv thaiv kev hloov PTFE raj ntawm 3D tshuab luam ntawv
Yuav ua li cas hloov 3D tshuab luam ntawv PTFE raj
Nws yog qhov yooj yim heev los hloov PTFE raj nrog lub tshuab luam ntawv 3D.Lub filament hose txuas rau ob sab los ntawm kev sib txuas.Siv ib lub qhov qhib-kawg los loosen cov coupling counterclockwise.Thaum lub coupling ua xoob, disassemble tag nrho.Koj ua li no rau ob sab.Tom qab ntawd ntsuas qhov ntev ntawm lub raj filament thiab hloov nws nrog tib qhov ntev.Muaj ntau tus nab laus, thiab koj tuaj yeem pom cov cim ntawm lub hose.Qhov no kuj qhia tau hais tias nyob deb npaum li cas lub raj yuav tsum dhau los ntawm kev sib txuas.Yog tias koj khaws qhov ntev tib yam, lub taub hau 3d luam tawm tuaj yeem txav tau yooj yim
