Aramid ntawv (tseem hu ua "polyarylamide fiber ntau daim ntawv") yog tsim los ntawm aramid luv fibers thiab aramid precipitated fibers li papermaking raw khoom. Nws yog ntub tsim los ntawm oblique mesh weaving thiab ces kub nias. Nws lub luag haujlwm tseem ceeb yog siv rau hauv kev lag luam xws li kev lag luam tub rog, tsheb, nkoj tshuab, thiab lwm yam. Nws muaj zog corrosion kuj. Qee cov khoom tseem ceeb xws li dav hlau, tsheb ciav hlau ceev, cov tsheb thauj neeg mob, cov dav hlau thauj loj, thiab cov tsheb thauj khoom yuav tsum siv cov khoom sib xyaw ua los ntawm "daim ntawv". Nws kuj yog ib qho khoom siv rwb thaiv tsev. Thaum ob qho khoom siv hluav taws xob hauv cov tshuab tau muab tso ua ke, nws yuav tsum tau muab tso rau hauv nruab nrab raws li qhov nruab nrab kom tsis txhob muaj kev cuam tshuam ntawm ob qho khoom. Nws tseem tuaj yeem tiv thaiv ob yam khoom. Qee cov khoom tseem ceeb, xws li lub cav, muaj kev tiv thaiv los ntawm kev yaig tshuaj lom neeg, yog li ua kom lub neej ua haujlwm ntawm lub tshuab.
Txawm li cas los xij, yav dhau los, cov khoom siv no tau ua tiav los ntawm DuPont hauv Tebchaws Meskas. Tom qab 50 xyoo ntawm txoj kev loj hlob, DuPont tau tsim peb tiam ntawm high-performance aramid ntawv, uas yog ntau tshaj ob zaug ntawm kev ua tau zoo ntawm thawj tiam khoom. Txawm li cas los xij, Tebchaws Meskas nruj me ntsis tswj kev xa tawm ntawm aramid ntawv mus rau Tuam Tshoj, thiab DuPont tsuas yog xa tawm thawj tiam cov khoom lag luam nrog kev ua haujlwm tsis zoo rau Tuam Tshoj. Nws tau hais tias cov khoom lag luam tsis tshua muaj neeg pej xeem tuaj yeem raug xa tawm, thaum cov khoom lag luam tshwj xeeb yog raug rau kev lag luam. Ua rau cov khoom siv high-end aramid nyob rau hauv peb lub teb chaws yuav tsum tau tswj los ntawm lwm tus neeg, peb yuav tsum "saib neeg lub qhov muag".
Feem ntau ntawm cov aramid siv nyob rau hauv peb lub teb chaws cia siab rau imports. Txhawm rau rhuav tshem qhov xwm txheej no, ntau lub tuam tsev hauv lub tebchaws tau rov hais meej meej suav nrog aramid hauv txoj cai tswjfwm ntawm kev txhawb nqa tseem ceeb rau kev txhim kho. Kev tshawb fawb txog kev ua tau zoo aramid daim ntawv engineering technology tau teev tseg raws li kev tshawb fawb thiab thev naus laus zis tseem ceeb los ntawm National Defense Science thiab Technology Commission, thiab aramid daim ntawv raws li cov khoom siv tau koom ua ke ua ib txoj haujlwm tshawb fawb tseem ceeb hauv tebchaws los ntawm Ministry of Science thiab Technology, Ministry of General Assembly, thiab National Defense Science thiab Technology Commission.
Qhov tseem ceeb ntawm Longbang lub siab hluav taws xob rwb thaiv tsev aramid daim ntawv yog qhov {{{0}}} {{0}}}. {4}}.76mm specification yog tag nrho siab dua DuPont. Piv nrog rau DuPont cov khoom lag luam flagship T410 rwb thaiv tsev ntawv, Longbang L633A siab hluav taws xob muaj zog rwb thaiv tsev aramid daim ntawv muaj kev ruaj ntseg zoo dua thiab rwb thaiv tsev.
Thaum nws los txog rau daim ntawv aramid, 78 xyoo Academician Chen Kefu zoo siab heev. Nws tau hais tias kev lag luam ntawm aramid cov ntaub ntawv sib xyaw muaj qhov cuam tshuam tseem ceeb rau Tuam Tshoj txoj kev tiv thaiv kev tsim kho hauv tebchaws, ua cov haujlwm ua lag luam xws li dav hlau loj, tsheb ciav hlau ceev, nkoj tsim, lub zog, cov ntaub ntawv hluav taws xob, thiab lwm yam.
Nrog rau kev nce ceev ntawm huab cua huab cua nyob rau hauv xyoo tas los no, pej xeem ib puag ncig kev paub tau maj mam ntxiv dag zog, thiab cov tuam tsev muaj feem cuam tshuam tau ua tiav thiab ua tiav cov txheej txheem tiv thaiv ib puag ncig uas cuam tshuam nrog ntau thaj chaw thiab kev lag luam. Traditional electrostatic precipitator cov cuab yeej tsis tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm kev tiv thaiv ib puag ncig. Vim qhov kev ua tau zoo ntawm kev pom zoo ntawm lub hnab lim, lawv tau nthuav dav thiab siv nyob rau xyoo tas los no.
Lub hnab lim ua haujlwm nyob rau hauv qhov kub thiab txias thiab corrosive ib puag ncig ntev, yog li nws yuav tsum tau hais tias lub hnab lim yuav tsum muaj qee qhov kub thiab txias thiab corrosion kuj. Aramid fibers yog dav siv nyob rau hauv kev lag luam pom vim lawv superior high-temperature kuj, zoo acid thiab alkali corrosion kuj, zoo heev hnav thiab kev sib txhuam, thiab siab zog.
Tsis tas li ntawd, cov khaub ncaws tiv thaiv ua los ntawm aramid fibers muaj cov yam ntxwv ntawm kev sib tsoo, tsis yaj, thiab tsis tsim cov pa phem.
Aramid fiber ntau, zoo li lub zog hluav taws xob siab aramid ntawv, muaj cov tswv yim thev naus laus zis thiab yog cov khoom lag luam txiav hauv kev lag luam aramid. Nws tau raug qhuas nyob rau hauv kev sim ua lag luam thaum ntxov.
