Polytetrafluoroethylene (PTFE) yog ib tug semi-crystalline fluoropolymer.PTFE yog paub zoo rau nws daim ntawv thov raws li ib tug non-stick txheej rau chav ua noj lauj kaub thiab lauj kaub vim nws tshwj xeeb kub thiab corrosion kuj.
Dab tsi yogPTFE?
Cia peb pib peb txoj kev tshawb fawb txog qhov PTFE tiag tiag yog dab tsi.Txhawm rau muab nws lub npe tag nrho, polytetrafluoroethylene yog cov khoom siv hluavtaws uas muaj ob lub ntsiab lus yooj yim;carbon thiab fluorine.Nws yog muab los ntawm tetrafluoroethylene (TFE) thiab muaj qee yam khoom tshwj xeeb uas ua rau nws muaj txiaj ntsig zoo hauv ntau yam kev siv.Piv txwv li:
Cov ntsiab lus melting siab heev: Nrog lub melting point ntawm ib ncig ntawm 327 ° C, muaj ob peb lub sij hawm uas PTFE yuav puas los ntawm tshav kub.
Hydrophobic: Nws tiv taus dej txhais tau hais tias nws yeej tsis ntub, ua rau nws muaj txiaj ntsig hauv kev ua noj, hnav khaub ncaws thiab lwm yam.
Chemically inert: Feem ntau ntawm cov kuab tshuaj thiab tshuaj yuav tsis ua puas PTFE.
Tsawg coefficient ntawm kev sib txhuam: Cov coefficient ntawm kev sib txhuam ntawm PTFE yog ib qho qis tshaj ntawm cov khoom nyob hauv hav zoov, txhais tau tias tsis muaj dab tsi yuav lo rau nws.
Lub zog flexural siab: Nws muaj peev xwm khoov thiab flex, txawm tias qhov kub thiab txias, txhais tau tias nws tuaj yeem siv tau yooj yim rau ntau qhov chaw yam tsis tau poob nws txoj kev ncaj ncees.
Kev ua haujlwm ntawm PTFE
PTFE tuaj yeem pom nyob rau hauv granular, dispersion thiab nplua hmoov cov ntaub ntawv.Semi-crystalline PTFE muaj kub melting kub thiab yaj viscosity, ua raug extrusion thiab txhaj molding nyuaj.Kev ua PTFE yog, yog li ntawd, zoo ib yam li cov hmoov ua ntau dua li cov khoom siv yas.
Granular PTFE yog tsim nyob rau hauv cov dej-raws li kev ncua polymerization cov tshuaj tiv thaiv.Cov txiaj ntsig granular resin feem ntau ua tiav rau hauv cov duab los ntawm compression molding.PTFE dispersion khoom yog tsim nyob rau hauv ib tug zoo sib xws, nrog ntxiv dispersing agents.Cov khoom tawg tuaj yeem siv rau PTFE txheej lossis lawv tuaj yeem ua tiav rau hauv cov yeeb yaj kiab nyias los ntawm cov yeeb yaj kiab casting.PTFE hmoov yog tsim nyob rau hauv ib qho emulsion polymerization cov tshuaj tiv thaiv.Cov hmoov zoo uas ua tau tuaj yeem muab tshuaj txhuam extruded rau hauv PTFE tapes, PTFE tubing, thiab hlau rwb thaiv tsev, los yog siv los ua ib qho additive los ua kom corrosion kuj nyob rau hauv lwm yam ntaub ntawv polymeric.
Sab saum toj 5 Daim Ntawv Thov ntawm PTFE
1. Kev siv cov khoom tiv thaiv corrosion
Roj hmab, iav, hlau alloy thiab lwm yam ntaub ntawv tsis ua raws li qhov hnyav ntawm qhov kub thiab txias, siab thiab tshuaj lom neeg kev sib koom ua ke ib puag ncig vim lawv qhov tsis xws ntawm corrosion kuj.Txawm li cas los xij, PTFE muaj kev tiv thaiv corrosion zoo heev thiab yog li tau dhau los ua cov ntaub ntawv tseem ceeb corrosion-resistant rau roj av, tshuaj, textile thiab lwm yam lag luam.
2. Daim ntawv thov ntawm kev sib txhuam qis hauv kev thauj khoom
Cov roj lubrication tsis haum rau kev sib txhuam ntawm qee cov khoom siv, vim tias cov roj lubricating tuaj yeem yaj los ntawm cov kuab tshuaj thiab tsis ua haujlwm, lossis cov khoom lag luam hauv kev lag luam tshuaj, khoom noj, textile thiab lwm yam kev lag luam yuav tsum tsis txhob staining los ntawm lubricants.Yog li ntawd, PTFE yas, uas nws cov coefficient ntawm kev sib txhuam yog qis dua lwm yam khoom siv paub, tau dhau los ua cov khoom siv zoo tshaj plaws rau roj-dawb lubrication (direct load bearing) ntawm cov khoom siv tshuab.
3. Kev siv hluav taws xob thiab hluav taws xob
Inherent tsawg poob thiab me me dielectric tas li ntawm PTFE cov ntaub ntawv enables nws tus kheej mus ua enameled hlau rau micro motors, thermocouples thiab tswj li.PTFE zaj duab xis yog cov khoom siv rwb thaiv tsev zoo tshaj plaws rau kev tsim cov khoom siv hluav taws xob, xov tooj cua rwb thaiv tsev, cov hlua hluav taws xob, lub cev muaj zog thiab hloov pauv, thiab tseem yog ib qho ntawm cov khoom siv tsis tseem ceeb rau aerospace thiab lwm yam khoom siv hluav taws xob.
4. Kev siv tshuaj kho mob
Expanded PTFE yog purely inert thiab lom neeg adaptable heev, yog li nws tsis ua rau tsis lees paub los ntawm lub cev, tsis muaj kev mob tshwm sim ntawm tib neeg lub cev, tuaj yeem ua kom tsis muaj menyuam los ntawm txhua txoj kev, thiab muaj ntau yam microporous qauv.
5. Daim ntawv thov ntawm cov khoom tiv thaiv nplaum
Nrog rau qhov qis tshaj qhov nro ntawm cov khoom siv, PTFE Teflon tsis lo rau tej yam khoom.Ntxiv mus, nws muaj kev tiv thaiv zoo rau qhov kub thiab txias.Yog li ntawd, nws tau siv dav hauv kev tiv thaiv-nplaum feature ntawm cov lauj kaub uas tsis yog-stick.
Yog tias koj nyob hauv Ptfe Tube, 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 260 ℃, 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 Fluorineplastic Industry Co., Ltd. tshwj xeeb hauv kev tsim cov khoom zooPTFE hoses thiab rajrau 20 xyoo.Yog tias muaj lus nug thiab xav tau, thov koj xav tiv tauj peb kom paub ntau ntxiv tswv yim.
