Polytetrafluoroethene,luv luv:PTFE
Alias: PTFE, tetrafluoroethylene, yas huab tais, F4.
Qhov zoo ntawm PTFE
PTFEyog tshwj xeeb engineering plastics, tam sim no yog cov khoom siv corrosion-resistant, hu ua "yas huab tais".Cov yam ntxwv tseem ceeb yog kub thiab tsis kub tsis kam, corrosion kuj, siab rwb thaiv tsev, laus kuj, nws tus kheej lubrication.
Nws yog siv rau hauv aerospace, electronics thiab cov khoom siv hluav taws xob, tshuaj lom neeg kev lag luam, tshuab thiab khoom siv, khoom noj khoom haus thiab kev kho mob, twj, li qub thiab kav dej, tsheb thiab nkoj, cua compressors, thiab lwm yam. kev lag luam.
PTFE molecule inert F atoms shielding thiab tiv thaiv CC daim ntawv cog lus, thiab CF bonding zog tshwj xeeb tshaj yog ruaj khov, cov saw molecular yog ib qho nyuaj rau kev puas tsuaj, yog ib tug ruaj khov qauv.Cov qauv molecular no kuj piav qhia cov khoom zoo hauv qab no ntawm PTFE.
Corrosion kuj:Ntxiv rau molten alkali hlau thiab ob peb cov kuab tshuaj xws li all-alkane hydrocarbons saum 300 degrees Celsius, nws yog resistant mus ntev corrosion los ntawm lwm yam tshuaj.
Kev ua haujlwm siab thiab qis qis: nws tuaj yeem siv tau ntev ntawm -60 + 260 ℃.
High lubrication:qhov tsawg tshaj plaws coefficient ntawm kev sib txhuam ntawm cov khoom siv, txawm tias dej khov tsis tuaj yeem piv nrog nws.
Tsis-adhesion:qhov tsawg tshaj plaws nto nro ntawm cov khoom siv, tsis lo rau tej yam khoom.
Huab cua Resistance:Lub neej ntev tshaj plaws ntawm cov yas.
Non-toxicity:cov khoom siv tuaj yeem siv los ua cov hlab ntsha, tsis muaj tshuaj lom thiab tsis ua xua thiab lwm yam kev phiv, rau cov khoom noj thiab tshuaj qib.
Insulating khoom:ib zaj duab xis tuab li ib daim ntawv xov xwm yog txaus los tiv thaiv high voltage hluav taws xob ntawm 1500V.
Tsis tas li ntawd, PTFE kuj tsis muaj noo noo nqus, tsis-flammable, thiab tsis tshua muaj oxygen, ultraviolet lub teeb.
Disadvantages ntawm PTFE
Txawm hais tias PTFE muaj kev ua tau zoo heev, tab sis tsis tshua muaj zog txhua yam, loj coefficient ntawm linear expansion, tsis hnav tsis kam, tsis muaj creep kuj, tsis zoo thermal conductivity thiab lwm yam tsis zoo.Nyob rau hauv lub zog txhua yam thiab lwm yam nyuaj, xws li siv nyob rau hauv lub valve sealing kev lag luam thiab nws cov kev txwv tiag tiag ntawm kev nyab xeeb ntawm kev siv kub yog feem ntau nyob rau hauv -70 ~ + 150 ℃.Txhawm rau kom kov yeej cov kev tsis txaus no, PTFE resin tuaj yeem sau nrog cov neeg ua haujlwm txhawb nqa los txhim kho cov khoom siv kho tshuab, txhawm rau nthuav dav qhov kev thov ntawm nws cov ntaub ntawv.
Taw qhia rau cov khoom ntawm cov xim PTFE
Cov xim thawj ntawm PTFE yog mis nyuj dawb, thaum xim PTFE yog vim PTFE cov khoom siv yog ntim nrog cov khoom siv.Cov ntaub ntawv pabcuam tuaj yeem muab faib ua ob pawg raws li kev siv: tus neeg sawv cev txhim kho thiab xim hmoov tus neeg sawv cev.
Xim hmoov tus neeg sawv cev chav kawm: yog sau nrog cov xim hmoov hauv PTFE, tuaj yeem ua xim dub, daj, liab, ntsuab, xiav thiab lwm yam.Xim hmoov tus neeg sawv cev tsuas yog hloov cov xim ntawm PTFE, qhov piv ntawm cov muab tub lim yog ib qho me me kom cov nyhuv ntawm PTFE qhov kev ua tau zoo qub tuaj yeem tsis quav ntsej.Raws li txoj cai, cov xim hmoov tus neeg sawv cev yuav tsum muaj peev xwm cuam tshuam cov tshuaj stability ntawm PTFE, rwb thaiv tsev, tensile zog thiab lwm yam khoom siv.Yog li ntawd, qee lub sijhawm tshwj xeeb yuav tsum paub txog nws.Xim PTFE ua tau raws li cov neeg siv khoom xav tau uas xav tau rau cov xim pom.
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.BesteflonFluorine yas Industry Co., Ltd. tshwj xeeb hauv kev tsim cov khoom zooPTFE hosesthiab raj rau 20 xyoo.Yog tias muaj lus nug txog ptfe tube thiab xav tau, thov koj xav tiv tauj peb kom paub cov lus qhia ntxiv.
