Fiberglass koob- punched Felt: Cov khoom siv ua haujlwm rau cov rwb thaiv tsev, pom, thiab suab rwb thaiv tsev.
Hauv fiberglass composite systems, koob - xuas nrig ntaus yog cov khoom siv tshwj xeeb uas feem ntau siv rau thermal rwb thaiv tsev, pom, suab rwb thaiv tsev, thiab hluav taws kub. Tsis zoo li chopped strand lev thiab deg lev, uas tsom rau kev txhawb nqa thiab ua tiav, rab koob - punched xav tias tseem ceeb tshaj plaws ntawm kev tiv thaiv lub cev thiab kev pom ib puag ncig, ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv hauv kev lag luam, cov cuab yeej tiv thaiv ib puag ncig, thiab lub suab thiab cua sov.
Fiberglass koob - xuas nrig ntausyog tsim los siv ib rab koob - xuas nrig ntaus cov txheej txheem. Lub koob- xuas nrig ntaus ntawm cov cuab yeej cuam tshuam cov fibers, tsim kom muaj qhov ruaj khov thiab ntxeem tau peb- cov qauv fiber ntau. Tag nrho cov txheej txheem tsim yuav tsum tsis muaj cov tshuaj binders, ua rau cov khoom muaj kev nyab xeeb thiab nyab xeeb dua. Nws khaws cia zoo heev -kub tsis kam, ua rau nws haum rau ntau yam siab - kub thiab kev ua haujlwm nyuaj. Qhov no zam cov teeb meem ntawm siab - kub aging, volatilization, thiab tsw muaj feem xyuam nrog cov khoom siv sib xyaw ua ke, muab kev nyab xeeb zoo dua thiab ua haujlwm ntev.
Nrog nws cov qauv ntawm lub cev tshwj xeeb, rab koob- xuas nrig ntaus muaj ntau lub zog zoo tshaj plaws: siab tag nrho cov khoom loj thiab zoo ib yam, permeable hauv pores, muab cov huab cua zoo permeability thiab pom tseeb, cuam tshuam cov plua plav thiab impurities zoo; tib lub sijhawm, nws nthuav tawm cov khoom siv hluav taws xob zoo tshaj plaws thiab lub suab rwb thaiv tsev, zoo thaiv kev hloov hluav taws xob thiab txo cov suab nrov; ua ke nrog lub siab - kub tsis kam thiab muaj zog ruaj khov ntawm nkauj xwb fiberglass, koob - xuas nrig ntaus muaj ntau yam zoo xws li ib puag ncig tus phooj ywg, kub tsis kam, siab pom kev ua haujlwm zoo, thiab muaj zog lub suab thiab cua sov rwb thaiv tsev, ua rau nws cov kev ua haujlwm zoo dua li cov ntaub ntawv zoo tib yam.
Vim nws cov khoom siv tau zoo heev, koob fiberglass - xuas nrig ntaus muaj qhov meej heev thiab dav - ntau yam kev siv. Hauv kev lag luam kev tiv thaiv ib puag ncig, nws tuaj yeem siv los ua kev lag luam siab -kub plua plav tshem tawm cov khoom siv lim dej, cov khoom siv tiv thaiv ib puag ncig, thiab lim cua txias, ua kom tiav qhov pom thiab ua kom huv ntawm cov pa roj av; Nyob rau hauv lub tshav kub rwb thaiv tsev, nws yog feem ntau siv rau ntau yam kev lag luam pipeline rwb thaiv tsev thiab cov khoom siv hluav taws xob rwb thaiv tsev txheej, ruaj khov rau hauv qhov kub thiab txias, cais siab - qhov kub thiab txias, thiab txhim kho cov khoom siv kev nyab xeeb; nyob rau hauv kev thauj mus los thiab pej xeem sector, nws yog lub hauv paus ntsiab lus ntawm automotive suab rwb thaiv tsev paj rwb, zoo absorbing suab nrov thiab txhim kho kev tsav tsheb.
Raws li kev ua haujlwm sub-cov ntaub ntawv ntawm fiberglass, koob- xuas nrig ntaus tau dhau los ua cov khoom tseem ceeb tshwj xeeb hauv thaj chaw muaj kev tiv thaiv ib puag ncig, lub zog- txuag rwb thaiv tsev, txo suab nrov thiab tiv thaiv hluav taws vim nws cov txiaj ntsig tseem ceeb ntawm tsis muaj tshuaj ntxiv, kub tsis kam, huab cua permeability, zoo pom, thiab muaj zog lub suab thiab cua sov. Nws muab kev lav zoo rau lub zog- txuag kev ua haujlwm, kev tiv thaiv kev nyab xeeb thiab kev ua kom huv ntawm ntau yam khoom siv.
