Taw qhia rau Oxidized PAN Fibers

Oxidized polyacrylonitrile (PAN) fibers tsis hlawv, yaj, muag, los yog poob. Raws li kev lees paub thoob ntiaj teb uas tsis yog hluav taws xob hluav taws xob hluav taws xob kev lag luam tus qauv, nws tuaj yeem siv rau ntau qhov chaw sib txawv raws li cov khoom siv hluav taws xob zoo thiab rwb thaiv tsev. Nws tus nqi LOI yog ntau dua 45%, ntau dua li LOI qhov tseem ceeb ntawm lwm cov fibers, thiab ua tau raws li qib combustion Sa ntawm DIN 66083.

Qhov zoo tshaj plaws fibers rau textile technology

Peb cov oxidized PAN fibers muaj ntau yam kev siv thiab tuaj yeem siv tau yooj yim hauv ntau cov txheej txheem textile los tsim cov kev ua haujlwm siab, kev lag luam, nplaim hluav taws xob, thiab cov ntaub ntawv insulating. Peb muab cov hlua txuas txuas ntxiv, curled thiab tsis curled luv fibers, nrog rau milled fibers ntawm txawv fiber ntau diameters, ntev, ntom, thiab ntau thiab tsawg.

Nta

1. LOI value>45%

2. Kev tiv thaiv hluav taws zoo heev

3. Kub kub tsis kam

4. Optimize textile ua

5. Kev sib xyaw ua ke thiab kev coj tus cwj pwm zoo

Curled PAN fibers

Curled PAN fibers yog tsim los ntawm cov fiber ntau txuas ntxiv. Lawv muab qhov tshwj xeeb loj los txhim kho kev sib koom ua ke. Tsis tas li ntawd, ua tib zoo optimized curl qib ua kom muaj kev ruaj ntseg thiab txhim khu kev qha ntawm cov txheej txheem combing, nrog cov khoom tsim tau zoo. Curled luv fibers muaj ntau qhov ntev los xaiv los hloov mus rau cov txheej txheem sib txawv thiab cov khoom siv.

Tsis yog curled staple PAN fibers

Tsis yog curled staple fibers yog siv rau kev sib xyaw thiab molding daim ntaub ntawv, muab ib tug textured nto tsos rau cov khoom nyob rau hauv lub tsheb, railway, thiab nkoj daim ntaub ntawv. Ntxiv rau kev txhim kho kev zoo nkauj ntawm cov chaw no, PAN fibers kuj txhim kho qhov hluav taws kub thiab tshuaj tiv thaiv ntawm cov khoom no.

Milled PAN fibers

Milled fibers rau kev sib txhuam-intensive daim ntaub ntawv

Milled PAN fibers yog siv los ua tsis muaj teeb meem thiab kub-resistant organic fiber fillers rau nres thiab txhuam cov ntaub ntawv. Cov fibers no yog cov khoom siv zoo tshaj plaws rau cov khoom phom sij xws li asbestos. Cov ntawv thov muaj xws li hluav taws xob nres tsheb, kev ua haujlwm siab ntawm lub tsheb nres tsheb, tsheb ciav hlau nres, thiab lub elevator kev sib txhuam.

Hom kev siv

PAN Fibers tuaj yeem tsim cov fibers luv luv los ntawm kev txiav thiab kev ua haujlwm, uas tuaj yeem muab spun rau hauv xov paj thiab tom qab ntawd tshuab woven rau hauv hluav taws-resistant ntaub.

Hauv kev lag luam automotive, yias fiber ntau yog siv dav hauv kev tsim cov khoom siv cav, thiab nws cov kev kub siab zoo heev tuaj yeem siv rau hauv lub cav ntim ntawm lub tsheb. Cov khoom siv hluav taws xob tiv thaiv hluav taws xob thiab cov nres nres siv hauv cov tsheb ciav hlau ceev thiab dav hlau hauv tib neeg lub neej txhua hnub kuj zoo ib yam. Hom carbon brake disc no muaj kev ua haujlwm zoo dua thiab hnav tsis kam piv rau cov khoom siv hlau zoo tib yam, thiab muaj lub neej ua haujlwm ntev dua.

Hais txog lub tsheb sab hauv, PAN fiber ntau kuj tau ua lub luag haujlwm tseem ceeb. Nws yog siv los tsim cov khoom siv rau lub rooj zaum hauv tsheb, ntaub pua plag, thiab kho kom zoo nkauj sab hauv. Cov khoom siv no tsis yog tsuas yog muaj qhov zoo nkauj zoo nkauj xwb, tab sis kuj muaj kev tiv thaiv zoo heev thaum tshav kub kub thiab nplaim taws, uas tuaj yeem tiv thaiv hluav taws zoo thiab txhim kho kev nplij siab thiab kev nyab xeeb ntawm lub tsheb.

Ntxiv rau daim ntawv thov kev tiv thaiv hluav taws, cov khoom lag luam customized yias kuj tuaj yeem siv rau hauv cov khoom siv hluav taws xob rau cov roj teeb loj loj. Nyob rau hauv lub neej yav tom ntej, cov khoom tshiab no yuav ua kom pom nws lub peev xwm hauv ntau qhov chaw.
