Puas yog PTFE tib yam li carbon fiber?

PTFEthiab carbon fiber tsis yog tib yam khoom.Niaj hnub no, peb yuav qhia ob yam ntaub ntawv rau koj.

PTFE yog cov yas uas muaj fluorine, tseem hu ua Teflon, Teflon, thiab lwm yam.PTFE yastseem hu ua King of Plastics vim nws qhov kev ua tau zoo tshaj plaws hauv txhua yam.PTFE tuaj yeem tiv taus corrosion, siab thiab qis kub, tsis muaj tshuaj lom, rwb thaiv tsev zoo, tiv thaiv kev laus, siab lubrication, thiab lwm yam khoom zoo heev.Txawm li cas los xij, muaj ntau yam khoom uas yuav tsum tau txhim kho, xws li creep, tsis yog-stick, abrasion kuj, kab o thiab siab tsis kam, hardness thiab lwm yam.Txhawm rau txhim kho cov khoom no ntawm PTFE, lwm yam khoom xws li molybdenum disulfide, iav fiber ntau, graphite, polyphenylene resin, iav fiber ntau, thiab hlau hmoov tuaj yeem muab ntxiv rau cov khoom siv raw ntawm PTFE hauv kev faib ua feem.Qhov sib ntxiv ntawm carbon fibers yog ib qho kev hloov kho PTFE cov khoom.Lub luag haujlwm ntawm cov pa roj carbon fiber ntau hauv kev sau PTFE yog txhawm rau txhawm rau txhawm rau ua haujlwm, thauj khoom tsis kam, hnav tsis kam, qhov ruaj khov, lub zog tensile thiab lwm yam khoom ntawmPTFE siv.

Cov pa roj carbon fiber ntau (CF luv luv) yog hom tshiab ntawm cov khoom siv fiber ntau nrog lub zog siab thiab siab modulus uas muaj ntau tshaj 95% carbon.Nws yog cov khoom siv microcrystalline graphite ua los ntawm cov organic fibers xws li flake graphite microcrystals stacked nyob rau hauv axial kev taw qhia ntawm cov fibers, uas yog ua los ntawm carbonization thiab graphitization.Cov pa roj carbon fiber yog "mos rau sab nraud tab sis nruj rau sab hauv", sib dua hauv huab hwm coj ntau dua li txhuas tab sis muaj zog dua hlau, thiab muaj cov yam ntxwv ntawm kev tiv thaiv corrosion thiab siab modulus, ua rau nws yog ib qho tseem ceeb ntawm kev tiv thaiv thiab kev siv pej xeem.Nws tsis tsuas yog muaj cov khoom siv hauv nruab nrab ntawm cov ntaub ntawv carbon, tab sis kuj muaj cov softness thiab processability ntawm textile fibers, ua rau nws yog ib tiam tshiab ntawm reinforcing fibers.Cov pa roj carbon fiber ntau muaj cov khoom zoo heev.Nws muaj zog axial siab thiab modulus, tsis muaj creep, zoo qaug zog tsis kam, tshwj xeeb kub thiab hluav taws xob conductivity ntawm cov hlau tsis muaj hlau thiab hlau, thiab zoo electromagnetic shielding.Lub coefficient ntawm thermal expansion yog me me, corrosion kuj yog qhov zoo, qhov ceev ntawm cov fibers yog tsawg, X-ray permeability yog zoo, lub loj yog lub teeb, thiab lub non-oxidizing ib puag ncig yog resistant rau ultra-siab kub.Piv nrog rau cov iav fibers, carbon fiber muaj ntau tshaj peb zaug Young's modulus.Piv nrog Kevlar, Young's modulus yog kwv yees li ob zaug siab, thiab nws yog insoluble thiab o nyob rau hauv cov organic solvents, acids thiab alkalis, thiab muaj zoo heev corrosion kuj.Qhov sib ntxiv ntawm cov pa roj carbon fiber ntau txhim kho lub peev xwm ntawm cov khoom siv sib xyaw, thiab ib qho me me ntawm graphite ntxiv rau tib lub sijhawm li PTFE ntxiv rau cov khoom ntim cov pa roj carbon fiber ntau.Qhov sib ntxiv ntawm graphite txo qhov coefficient ntawm kev sib txhuam ntawm cov pa roj carbon fiber ntau thiab cov khoom sib txuas, yog li txo qhov nyiam ntawm cov pa roj carbon fiber ntau kom poob tawm thiab txhim kho qhov hnav tsis kam ntawm cov khoom sib xyaw.
