PTFE yog dab tsi?
PTFE feem ntau hu ua "yas huab tais", yog ib qho polymer polymer ua los ntawm tetrafluoroethylene ua monomer.Nws tau tshawb pom los ntawm Dr. Roy Plunkett hauv xyoo 1938. Tej zaum koj tseem xav tias txawv ntawm cov khoom no, tab sis koj puas nco qab lub lauj kaub uas tsis yog nplaum uas peb siv?Lub lauj kaub uas tsis yog nplaum yog coated PTFE txheej rau ntawm qhov chaw ntawm lub lauj kaub, kom cov zaub mov tsis lo rau hauv qab ntawm lub lauj kaub, uas qhia txog PTFE qhov kub thiab txias tsis kam thiab cov yam ntxwv siab lubrication.Niaj hnub no, PTFE hmoov raw cov ntaub ntawv yog tsim rau hauv cov khoom ntawm ntau yam duab, xws li PTFE hlab, PTFE nyias zaj duab xis, PTFE tuav, thiab PTFE daim hlau, uas yog tag nrho cov siv nyob rau hauv txawv teb.Tom ntej no, peb tham txog daim ntawv thov ntawm PTFE raj hauv 3D tshuab luam ntawv li.
Puas yog PTFE Toxic?
Lub ntsiab lus ntawm seb PTFE puas muaj tshuaj lom yog qhov tsis txaus ntseeg thiab PTFE yog qhov tsis muaj tshuaj lom.
Tab sis thaum PFOA (Perfluorooctanoic Acid) yav tas los ntxiv rau PTFE cov khoom xyaw, cov tshuaj lom tau tso tawm thaum siv qhov kub thiab txias.PFOA nyuaj rau degrade los ntawm ib puag ncig, thiab tuaj yeem nkag mus rau tib neeg thiab lwm yam kab mob los ntawm cov khoom siv lub cev, huab cua thiab dej, thiab dhau sijhawm tuaj yeem ua rau txo qis qis thiab lwm yam kab mob hauv lub cev.Tab sis tam sim no PFOA tau raug txwv los ntawm cov tub ceev xwm ntxiv rau PTFE cov khoom xyaw.Tag nrho peb cov ntaub ntawv soj ntsuam cov ntaub ntawv raw kuj qhia tias tsis muaj PFOA tivthaiv.
Vim li cas 3D tshuab luam ntawv siv PTFE raj?
Nrog rau txoj kev loj hlob sai ntawm Lub Sijhawm, 3D tshuab luam ntawv yog lub tshuab tsim sai, tseem hu ua additive manufacturing.Nws yog cov txheej txheem ntawm kev sib txuas lossis kho cov ntaub ntawv nyob rau hauv kev tswj hwm lub computer los tsim cov khoom peb sab, feem ntau yog siv cov kua molecules los yog hmoov hmoov los fuse ua ke thiab thaum kawg tsim cov khoom txheej los ntawm txheej.Tam sim no, 3D tshuab luam ntawv moulding tshuab feem ntau suav nrog: cov txheej txheem melting deposition, xws li kev siv cov thermoplastic, siv lead ua cov ntaub ntawv hlau, nws cov molding ceev qeeb, thiab cov khoom melting fluidity zoo dua;
Txawm li cas los xij, 3D tshuab luam ntawv muaj keeb kwm keeb kwm ntawm kev mob taub hau, yooj yim rau ntsaws!Txawm hais tias qhov ua tsis tiav ntawm 3D tshuab luam ntawv yog tsawg, ib zaug nws tshwm sim, nws yuav tsis tsuas cuam tshuam rau kev luam ntawv zoo, tab sis kuj nkim sij hawm thiab cov ntaub ntawv luam tawm, thiab txawm tias lub tshuab puas.Ntau tus neeg xav tias lub caj pas caj pas kub dhau vim nws tau ua los ntawm cov khoom ntxiv.Vim tias cov ntaub ntawv qib engineering xav tau qhov kub tsis tu ncua, cov kev xav tau ntawm cov khoom siv yog siab heev.Yog li ntawd, lub tshuab luam ntawv 3D siv PTFE raj ua lub raj pub mis.Ntau cov ntaub ntawv raw yuav tsum tau thauj mus rau lub tshuab luam ntawv lub taub hau nyob rau hauv lub xeev melting, thiab lub raj thauj yuav tsum tau raws li qhov yuav tsum tau ntawm lub tshuab luam ntawv, yog li tam sim no ntau manufacturers hloov mus rau built-in hlau fluorine zaj raj, hlau fluorine zaj thiab stainless hlau. thermal conductivity yog tsawg, tuaj yeem txo qhov kub ntawm lub caj pas raj, nrog cov hlau fluorine zaj raj, ntsaws qhov tsis ua haujlwm yog txo qis heev.Yog li qhov no yog qhov kev xaiv zoo tshaj plaws rau 3D tshuab luam ntawv.
Yog tias koj nyob hauv 3D tshuab luam ntawv lag luam, Koj Yuav Nyiam
Cov hauv qab no yog cov lus qhia dav dav ntawm cov yam ntxwv tseem ceeb ntawm PTFE hlab:
1. Non-adhesive: Nws yog inert, thiab yuav luag tag nrho cov tshuaj tsis raug khi rau nws.
2. Thaum tshav kub kub tsis kam: ferroflurone muaj cov cua kub zoo heev.Kev ua haujlwm dav dav tuaj yeem siv tsis tu ncua ntawm 240 ℃ thiab 260 ℃.Lub sij hawm luv luv kub tsis kam mus rau 300 ℃ nrog lub melting point ntawm 327 ℃.
3. Lubrication: PTFE muaj qhov sib txhuam coefficient tsawg.Kev sib txhuam coefficient hloov thaum lub load swb, tab sis tus nqi tsuas yog nyob nruab nrab ntawm 0.04 thiab 0.15.
4. Huab cua tsis kam: tsis muaj kev laus, thiab lub neej zoo dua qub hauv cov yas.
5. Tsis muaj tshuaj lom: nyob rau hauv ib puag ncig ib puag ncig tsis pub dhau 300 ℃, nws muaj physiological inertia thiab tuaj yeem siv rau kev kho mob thiab khoom noj khoom haus.
Kev yuav txoj cai PTFE tubing tsis yog tsuas yog xaiv cov kev qhia tshwj xeeb rau kev siv sib txawv.Ntau dua los xaiv cov chaw tsim khoom txhim khu kev qha.Besteflon Fluorine yas kev lag luam Co., Ltd. specializes nyob rau hauv zus tau tej cov zoo PTFE hoses thiab hlab rau 15 xyoo.Yog tias muaj lus nug thiab xav tau, thov koj xav tiv tauj peb kom paub ntau ntxiv tswv yim.
