Dab tsi yog fiberglass lev?
Fiberglass lev, tseem hu ua nonwoven fiberglass lev, yog ib daim ntawv hloov tau -zoo li nonwoven fiberglass khoom ua los ntawm alkali-dawb tws fiberglass filaments raws li cov tub ntxhais raw khoom, ua ke nrog tshwj xeeb tshuaj binders, los ntawm ntub los yog qhuav nonwoven txoj kev. Cov txheej txheem suav nrog web laying, impregnation nrog nplaum, kho, ziab, winding, thiab txiav.
Tsis zoo li cov ntaub fiberglass tsoos, fiberglass lev tsis muaj warp thiab weft weave qauv. Cov fibers yog randomly faib thiab interwoven, ua rau lub teeb yuag, nyias, thiab uniformly ntxeem tau zoo nkauj nrog siab yooj. Nws tuaj yeem ua tau yooj yim khoov thiab khi rau qhov tsis sib xws ntawm cov substrates. Nws feem ntau qis hauv qab qhov hnyav yog vim li cas nws thiaj li txhais tau tias yog ib daim lev nyias.
Los ntawm cov txheej txheem tsim khoom, cov khoom tseem ceeb ntawm kev ua lag luam tau muab faib ua ob pawg loj: qhuav- pw lev thiab ntub- pw lev. Cov txheej txheem qhuav -ntev yog yooj yim, tus nqi- zoo, thiab tsim randomly nteg fibers nrog lub zog tensile zoo, ua rau nws haum rau kev siv dav dav - lub hom phiaj. ntub- pw lev muaj ntau yam fiber ntau dispersion, siab dua nto flatness, me thickness yuam kev, thiab ruaj khov huab cua permeability thiab impermeability. Nws feem ntau yog siv nyob rau hauv siab - tus qauv teb xws li siab - kawg tiv thaiv corrosion, hluav taws xob rwb thaiv tsev, thiab txheej txheej, thiab tam sim no yog qhov kev xaiv tseem ceeb rau siab - kawg kev lag luam xav tau.
Raws li cov ntaub ntawv muaj pes tsawg leeg thiab daim ntawv thov scenarios, fiberglass lev tuaj yeem muab faib ua ob peb pawg tseem ceeb, npog cov kev xav tau ntawm tag nrho kev lag luam. Cov pawg muaj xws li: fiberglass lev rau lub ru tsev waterproofing, yeeb nkab tiv thaiv -corrosion nto mats, pem teb anti-corrosion lev, roj teeb cais lev, hluav taws xob rwb thaiv tsev lev, hniav mats, thiab siab - kub resistant nplaim taws - retardant lev. Cov pawg sib txawv yog tsim los rau cov kev cai sib txawv ntawm qhov kub thiab txias, acid thiab alkali tsis kam, waterproofing, thiab rwb thaiv tsev los ntawm kev kho cov specifications ntawm fiberglass raw cov ntaub ntawv, nplaum formulations, thiab lub hauv paus yuag ceev.
Qhov laj thawj tseem ceeb vim li cas fiberglass mats tau ntev ua tus thawj coj ntawm cov khoom lag luam kev lag luam nyob hauv lawv qhov kev ua tau zoo. Ua ntej, lawv muaj cov tshuaj muaj zog heev, tiv taus acid thiab alkali corrosion, ntsev tsuag corrosion, thiab organic hnyav corrosion. Lawv tsis yooj yim rau kev laus los yog pwm loj hlob txawm tias tom qab lub sij hawm raug rau cov av noo thiab tshuaj corrosive ib puag ncig, zoo kawg nkaus ua tau raws li cov kev xav tau ntawm kev tiv thaiv kev tiv thaiv - tej yaam num.
Qhov thib ob, lawv nthuav tawm cov rwb thaiv tsev zoo thiab thermal rwb thaiv tsev. Fiberglass nws tus kheej tsis yog -conductive thiab muaj thermal conductivity tsawg. Ua ke nrog cov txheej txheem ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom qauv tsim tau zoo tiv thaiv kev hloov pauv ntawm tam sim no thiab cua sov, ua kom nws yog ib qho khoom siv zoo tshaj plaws rau cov khoom siv hluav taws xob, cov yeeb nkab rwb thaiv tsev, thiab phab ntsa rwb thaiv tsev.
Meanwhile, nws muaj cov kev pab zoo heev thiab compatibility. Nws cov qauv tsis sib haum xeeb pom muaj zog adhesion, tso cai rau nws sib txuas nrog ntau yam substrates xws li resin, asphalt, coatings, thiab cement mortar. Qhov no zoo tiv thaiv txheej txheej tawg, substrate efflorescence, thiab noo noo nkag mus, muab ntau lub zog ntawm kev txhawb zog, kev tiv thaiv seepage, tiv thaiv tawg, thiab kev tiv thaiv. Tsis tas li ntawd, nws cov nplaim hluav taws kub nyhiab, hluav taws kub tsis kam, kev laus ua haujlwm, yooj yim ntawm kev tsim kho, thiab tus nqi siab -kev ua tau zoo kuj yog qhov tseem ceeb ntawm fiberglass xav tau.
Kev siv ntau qhov kev ua tau zoo, fiberglass xav tau twb nkag mus rau ntau yam kev lag luam. Hauv kev tsim kho, raws li cov khoom siv hauv cov khoom siv dej tsis zoo, nws yog siv rau hauv vov tsev, hauv qab daus, thiab chav dej dej ua haujlwm los txhim kho qhov tawg tsis kam thiab kev pab cuam lub neej ntawm cov dej tsis zoo. Hauv kev lag luam los tiv thaiv -corrosion kev lag luam, nws tau dav siv los ua cov khoom siv sab hauv thiab sab nraud los tiv thaiv- cov kab mob corrosion rau cov kav dej tshuaj, cov tso tsheb hlau luam, cov qauv hlau, thiab cov dej phwj tuaj kho cov pas dej, txhim kho kev ruaj ntseg ntawm cov tshuaj tiv thaiv -corrosion txheej.
Hauv kev siv hluav taws xob thiab hluav taws xob tshiab, ultra- fiberglass xav tau yog siv los ua cov roj teeb cais, Circuit Court board substrates, thiab hluav taws xob rwb thaiv tsev npog kom ntseeg tau tias cov khoom siv hluav taws xob muaj kev nyab xeeb. Hauv cov khoom siv hauv tsev thiab kho kom zoo nkauj, fiberglass xav tau siv rau hauv phab ntsa cladding, qab nthab substrates, thiab sab nrauv phab ntsa rwb thaiv tsev txheej, ntsuas qhov zoo nkauj thiab kev tiv thaiv. Tsis tas li ntawd, nws yog qhov tseem ceeb hauv cov phiaj xwm hauv pem teb, automotive interiors, ventilation ducts, thiab ib puag ncig pom.
Zuag qhia tag nrho, thaum fiberglass xav tias zoo li cov qauv yooj yim, nws yog ib qho khoom siv zais tsis tau tseem ceeb hauv kev tsim khoom, kev tsim kho vaj tse, thiab kev lag luam tshiab. Nrog kev hloov kho hauv kev tiv thaiv corrosion, qhov nrov ntawm cov khoom siv hauv tsev ntsuab, thiab kev loj hlob sai ntawm kev lag luam hluav taws xob tshiab, kev lag luam hauv qab xav tau rau qis - hnyav, huab cua heev - tiv taus, thiab ib puag ncig zoo fiberglass xav tau nce ntxiv. Kev lag luam tseem niaj hnub ua kom zoo rau cov txheej txheem, rov ua kom lub teeb yuag, siab - ua tau zoo, thiab cov kev daws teeb meem.
