Vim li cas Aramid Fibers yog qhov kev xaiv zoo tshaj plaws hauv ntau daim ntaub ntawv tiv thaiv

Thawj cov hluavtaws hluavtaws-retardant inherent fiber yog thawj zaug nkag rau hauv cov ntawv thov kev lag luam ntau tshaj 50 xyoo dhau los, hloov pauv cov khaub ncaws tiv thaiv rau kev siv tub rog thiab kev lag luam. Raws li tus kws tshaj lij kev ruaj ntseg, tej zaum koj yuav paub txog Kevlar®, Nomex®, Twaron®, thiab Kermel®. Lawv yog tag nrho cov tshav kub-resistant thiab muaj zog hluavtaws fibers hu ua "aramids". Txawm tias muaj ntau yam kev xaiv muaj nyob rau hauv kev ua lag luam niaj hnub no, aramid fibers tseem yog ib qho kev xaiv zoo tshaj plaws hauv ntau daim ntawv thov kev tiv thaiv. Nyeem qhov blog no kom paub seb qhov no puas yog rau koj cov khaub ncaws tiv thaiv.

Keeb kwm thiab siv aramid fiber ntau

Aramid, los yog "aramid" nyob rau hauv tag nrho sau ntawv, tau qhia nyob rau hauv thaum ntxov 1960s. Cov tuam txhab pib siv polyamides rau kev lag luam kev lag luam los ntawm kev sib xyaw ua ke.

Cov aramids muaj ob hom, para-aramid thiab meta-aramid. Para-aramids Ameslikas tsim los rau kev ua tsov ua rog, raws li lawv tau siv rau hauv kev siv high-tech hauv aerospace thiab tub rog. Lawv muaj txog li 7 npaug ntawm lub zog tensile ntawm cov hlau ntawm tib qhov hnyav. Ib qho kev paub zoo ntawm para-aramid variant yog Kevlar®, uas feem ntau siv rau hauv cov khoom siv lub cev muaj zog.

Lwm hom aramid, hu ua meta-aramid, paub txog nws cov cua sov zoo heev thiab nplaim taws. Raws li tus kws tshaj lij kev nyab xeeb kev lag luam, tej zaum koj tau hnov ​​​​txog meta-aramid ntawm qee kis. Nomex® yog lub npe hu ua meta-aramid siv hauv kev tua hluav taws thiab tiv thaiv khaub ncaws hauv kev lag luam.

Niaj hnub no, aramids feem ntau siv rau hauv kev lag luam petrochemical vim lawv cov tshuaj tiv thaiv zoo. Txawm li cas los xij, cov kev daws teeb meem hluav taws kub retardant muaj ntau dua li aramid fibers hauv kev lag luam hlau thiab hlau. Qhov no feem ntau yog vim qhov sib txawv ntawm tus nqi thiab qhov tseeb tias cov nplaim hluav taws xob kho tau muaj kev tiv thaiv zoo txaus rau kev lag luam.

Lub zog ntawm Aramid Fibers

Thaum muaj lwm txoj hauv kev tshiab, aramids tseem siv tau rau ntau daim ntawv thov. Lawv muaj ntau yam zoo, uas peb tuaj yeem sau cov hauv qab no:

Excellent heat resistance and flame retardancy: the flame retardancy and heat resistance are very good. Aramid fibers will not melt or ignite under normal oxygen levels and their melting point can be as high as >500 degree.

Cov tshuaj lom neeg ua haujlwm siab: Txij li aramid fibers yog 100 feem pua ​​​​ntawm cov hluavtaws, aramid fibers yog qhov zoo dua rau cov kev pheej hmoo xws li flashovers thiab tshuaj txhuam hniav.

Tsawg Molecular Luj: Cov fiber ntau no muaj zog dua li cov khoom xws li paj rwb. Qhov no txhais tau hais tias cov ntaub tsim los ntawm aramid fibers tuaj yeem hnav tau heev thiab tseem muab kev tiv thaiv qib siab.

Raws li koj tuaj yeem pom, Kevlar muaj kev tiv thaiv qib siab hauv cov xwm txheej tshwj xeeb. Nws yog ib qho tseem ceeb rau koj kom nkag siab seb koj puas xav tau qib kev tiv thaiv no lossis yog tias nws yuav ntau dhau rau koj cov kev xav tau tshwj xeeb. Yog tias muaj, muaj lwm yam kev xaiv muaj.

Puas yog Aramid Fiber Qhov Kev Xaiv Zoo rau Koj Cov Khaub Ncaws Tiv Thaiv?

Los ntawm kev nyeem cov kab lus no, peb cia siab tias koj nkag siab txog cov txiaj ntsig ntawm Kevlar. Txhawm rau txiav txim siab seb lawv puas haum rau koj cov khaub ncaws tiv thaiv, koj yuav tsum nkag siab tag nrho cov kev xav tau tshwj xeeb ntawm koj qhov chaw ua haujlwm. Rau qee qhov kev siv, xws li cov neeg tua hluav taws, nws yog qhov kev xaiv zoo tshaj plaws. Rau lwm daim ntawv thov, muaj lwm txoj hauv kev, thiab koj tuaj yeem xaiv raws li koj nyiam rau kev tiv thaiv, qhov hnyav, thiab tus nqi.
