Qhov zoo ntawm iav Fiber hauv Graphite-based Chemical Equipment

Graphite yog dav siv nyob rau hauv cov cuab yeej siv tshuaj vim nws zoo heev corrosion kuj, hluav taws xob conductivity, thiab thermal stability. Txawm li cas los xij, graphite nthuav tawm cov khoom siv tsis muaj zog, tshwj xeeb tshaj yog nyob rau hauv kev cuam tshuam thiab kev co.iav fiber ntau, raws li cov khoom siv sib xyaw ua haujlwm siab, muaj qhov zoo tseem ceeb thaum siv rau graphite-raws li cov khoom siv tshuaj lom neeg vim nws cov cua sov ua haujlwm, tiv thaiv corrosion, thiab cov khoom siv zoo dua. Cov txiaj ntsig tshwj xeeb suav nrog:

(1) Txhim kho Mechanical Performance

Lub zog tensile ntawm iav fiber ntau tuaj yeem ncav cuag 3,450 MPa, deb tshaj li ntawm graphite, uas feem ntau yog li ntawm 10 txog 20 MPa. Los ntawm kev sib xyaw cov iav fiber ntau rau hauv cov khoom siv graphite, tag nrho cov khoom siv kho tshuab tuaj yeem txhim kho tau zoo, suav nrog kev tiv thaiv kev cuam tshuam thiab kev co.

(2) Corrosion Resistance

Cov iav fiber ntau qhia tau zoo heev rau feem ntau cov kua qaub, alkalis, thiab cov kuab tshuaj. Thaum graphite nws tus kheej yog cov corrosion-resistant,iav fibertej zaum yuav muaj kev ua tau zoo tshaj plaws nyob rau hauv ib puag ncig tshuaj lom neeg, xws li qhov kub thiab txias siab, oxidizing atmospheres, lossis hydrofluoric acid ib puag ncig.

(3) Txhim kho Thermal Properties

Cov iav fiber ntau muaj cov coefficient tsawg heev ntawm thermal expansion (CTE) ntawm kwv yees li 5.0 × 10-7 / ° C, ua kom muaj kev ruaj ntseg nyob rau hauv thermal stress. Tsis tas li ntawd, nws cov ntsiab lus melting siab (1,400-1,600 ° C) muab qhov ua tau zoo ntawm qhov kub thiab txias. Cov yam ntxwv no ua rau cov khoom siv iav fiber ntau ntxiv graphite kom muaj kev ncaj ncees ntawm cov qauv thiab kev ua haujlwm hauv qhov chaw kub kub nrog tsawg deformation.

(4) Qhov zoo ntawm qhov hnyav

Nrog rau qhov ntom ntom ntawm kwv yees li 2.5 g / cm3, iav fiber ntau hnyav dua li graphite (2.1-2.3g / cm3) tab sis hnyav dua li cov khoom siv hlau xws li hlau lossis txhuas. Kev sib xyaw iav fiber ntau rau hauv cov khoom siv graphite txhim kho kev ua tau zoo yam tsis muaj qhov hnyav ntxiv, khaws cia cov khoom siv lub teeb yuag thiab txav tau yooj yim.

(5) Tus nqi siv tau

Piv nrog rau lwm cov khoom ua tau zoo (piv txwv li, carbon fiber), iav fiber ntau yog tus nqi zoo, ua rau nws muaj txiaj ntsig zoo rau kev lag luam loj:

Cov nqi raw khoom:iav fiber ntauFeem ntau siv cov iav uas tsis tshua muaj nqi, qhov carbon fiber cia siab rau kim acrylonitrile.

Tus nqi tsim khoom: Ob qho khoom siv yuav tsum tau ua kom muaj qhov kub thiab txias, tab sis cov pa roj carbon fiber ntau muaj cov kauj ruam ntxiv (xws li, polymerization, oxidation stabilization, carbonization), tsav cov nqi.

Recycling thiab pov tseg: Cov pa roj carbon fiber ntau yog qhov nyuaj rau kev rov ua dua tshiab thiab ua rau muaj kev pheej hmoo ib puag ncig yog tias ua tsis raug, ua rau cov nqi pov tseg ntau dua. Cov iav fiber ntau, qhov sib txawv, yog tswj tau ntau dua thiab eco-friendly nyob rau hauv qhov kawg ntawm lub neej scenarios.
