Yuav Ua Li Cas Ntxiv - Seed PTFE Coatings Txhim Kho Kev Txhim Kho Ntawm Cov Cuab Yeej Cuab Yeej?

Pure PTFE yog chemically inert thiab tsis yog -stick, tab sis yog mos mos thiab tuaj yeem hnav los ntawm cov khoom abrasive hauv slurries lossis los ntawm kev sib cuag. PTFE PTFE coatings muaj cov khoom nyuaj los txhim kho kev hnav tsis kam yam tsis muaj kev cuam tshuam cov tshuaj inertness. Qhov kev tsim kho tshiab no yog kev txhim kho cov kav ntev thiab kev ua haujlwm ntawm cov cua sov sheaths hauv kev siv tawv tawv.

Technology ntawm Additive Seeded PTFE Txheej
Ntxiv - cov noob PTFE txheej yog tsim los ntawm kev sib txuas PTFE resin nrog cov khoom me me ntawm cov ntaub ntawv nyuaj xws li ceramic (alumina, silicon carbide) lossis carbon fiber ua ntej sintering. Cov txheej txheej tsim muaj cov Islands tuaj ntawm cov khoom tawv tawv hauv PTFE matrix, uas muaj kev tiv thaiv zoo dua, thaum tuav cov yam ntxwv tseem ceeb ntawm PTFE, xws li nws cov tshuaj tsis haum, tsis muaj kev sib txhuam, thiab tsis yog - cov yam ntxwv ntawm cov nplaum.

Cov ntsiab lus nyuaj no tau tawg mus rau hauv PTFE txheej, tab sis lawv qhov ntim yog me me. Lawv ua haujlwm raws li kev tiv thaiv kev puas tsuaj thiab yog li tiv thaiv PTFE hauv qab los ntawm kev hnav thiab txuas ntxiv lub neej ntawm lub tshuab cua sov yog tias muaj cov slurries abrasive lossis kev sib cuag nrog cov neeg kho tshuab. Cov khoom muab tub lim tsis zoo heev cuam tshuam rau qhov zoo ntawm PTFE, tab sis txhim kho nws txoj kev tiv thaiv kev puas tsuaj los ntawm sab nraud.

Qhov zoo ntawm Abrasive Conditions
Additive seeded PTFE coatings muaj txiaj ntsig zoo thaum muaj cov khoom abrasive tam sim no, xws li mining slurries, grit hauv dej khib nyiab, tshem tawm cov hlau hauv plating da dej, thiab lwm yam. Tab sis cov txheej txheej puv ua rau muaj kev hnav ntau dua thiab pab cov cua sov kom ntev dua thiab ua haujlwm hauv cov xwm txheej nyuaj no.

Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev siv xws li kev kho dej khib nyiab lossis kev ua haujlwm mining qhov twg grit thiab lwm yam khoom siv abrasive tuaj yeem hnav tawm lub tshuab cua sov. Kev txhim kho kev puas tsuaj ntawm PTFE txheej txheej ua kom cov cua sov ua haujlwm txuas ntxiv ua tiav yam tsis muaj kev hloov pauv ntau zaus. Ib yam li ntawd, additive seeded PTFE coatings muab ib tug txhim khu kev qha, ntev kev daws teeb meem nyob rau hauv plating ua hauj lwm qhov twg cov cua kub ntsiab tej zaum yuav cuam tshuam los ntawm hlau hais.

Chemical Resistance Compromise
Lub xub ntiag ntawm cov khoom tawv tsis pab nrog kev puas tsuaj tab sis nws yuav tsum nkag siab tias cov PTFE txheej muaj qee qhov kev lag luam. Nyob ntawm cov muab tub lim sib xyaw, ceramic lossis carbon fibers tuaj yeem degrade cov tshuaj tsis haum ntawm cov khoom marginally. Nyob ntawm lawv qhov kev ruaj ntseg nyob rau hauv qhov chaw muab tshuaj ib co fillers kuj yuav muaj peev xwm mus rau hauv cov txheej txheem.

Yog li ntawd, kev xaiv cov khoom siv muab tub lim yog qhov tseem ceeb heev. Piv txwv li, alumina thiab silicon carbide yog qhov ruaj khov thiab sib haum nrog ntau cov kuab tshuaj, uas ua rau lawv zoo meej rau cov ntawv thov uas muaj tshuaj tiv thaiv tseem yog qhov tsim nyog. Nyob rau hauv qhov chaw uas qhov teeb meem tseem ceeb yog hnav tsis kam thiab tshuaj lom neeg raug xav tau tsawg dua, cov pa roj carbon-raws li cov khoom siv yuav tsim nyog dua, los ntawm kev sib piv.

Common Fillers thiab lawv siv rau dab tsi
Feem ntau, cov khoom siv ntxiv- cov noob PTFE txheej siv cov khoom sib txawv, txhua qhov nthuav qhia cov txiaj ntsig tshwj xeeb nyob ntawm daim ntawv thov npaj:

iav Fiber: Txhim kho txhua yam muaj zog thiab hnav tsis kam. Nws yog dav siv hauv sealing thiab bearings.

Cov pa roj carbon monoxide: Txhim kho kev tiv thaiv kev hnav thiab txo qis kev sib txhuam. Zoo rau cov ntawv thov uas raug cuam tshuam rau cov tshuaj.

Graphite yog ib qho kev sib haum xeeb zoo ntawm kev sib txhuam qis thiab hnav tsis kam thiab yog li tsim nyog rau cov roj lubrication qhuav thiab kub kub.

Molybdenum Disulphide: Nws paub txog qhov zoo ntawm lubricating zoo uas pab txo kev sib txhuam thiab hnav.

Alumina: Nyuaj thiab hnav tsis kam, nws yog qhov zoo rau kev ua haujlwm abrasive xws li mining slurries.

Filled PTFE yog siv dav hauv cov ntsaws ruaj ruaj, bearings thiab lwm yam khoom siv thiab tau txais kev muaj koob meej rau cov cua sov sheaths, tshwj xeeb tshaj yog nyob rau hauv kev lag luam uas puas yog qhov teeb meem loj.

Xaus
Additive-cov noob PTFE txheej uas muaj cov khoom siv ceramic lossis carbon fiber ntau tuaj yeem yog cov cuab yeej muaj txiaj ntsig zoo rau kev ua kom lub neej ntawm cov cua sov sheaths hauv cov chaw hnyav. Cov no txhim kho kev puas tsuaj tsis tau tswj hwm qhov tseem ceeb ntawm PTFE, tso cai rau kev siv cov fluoropolymer immersion heaters hauv cov haujlwm xws li mining, kev kho dej khib nyiab thiab plating. Raws li cov khoom siv engineering txuas ntxiv txhim kho thiab nthuav dav cov ciam teb ntawm PTFE lub peev xwm, cov txheej txheem tshiab no yuav yog qhov tseem ceeb hauv kev txhim kho cov kav ntev thiab kev ua haujlwm ntawm cov txheej txheem thermal.

Kev nce qib hauv PTFE coatings qhia txog kev siv cov ntaub ntawv tshawb fawb los ua kom tau raws li cov kev xav tau ntawm kev lag luam kev lag luam, qhia txog kev ua haujlwm thiab ua haujlwm ntev.
