UA TXHUA YAM NTAWM FIBERGLASS
Raugfiberglasskev tsim hluav taws xob tawm ntawm cov tshuaj tiv thaiv thiab cov khoom tawg ntawm cov khoom siv yog ua tiav ntawm 1400 ° C txog 1500 ° C hauv lub cub tawg lossis lub tshuab hluav taws xob "txias-saum" cub tawg. Cov khoom xyaw xyoob, cov av hauv av xws lisilica xuab zeb, limestone, dej qab zib-cov hmoov tshauv,borax, thiab, nce ntxiv, zuaj cov neeg tau txais kev pab tom qab lub raj mis thiab cov iav phaj, tau hnyav, muab kho ua ntej, thiab muab pub rau hauv qhov cub ua kom sov los ntawmsiv tawv conveyorlossis antsia hlau-feeder(saibFig. 2). Cov kev npaj tua hluav taws hauv qhov cub ua kom sov nrog sib xyaw nrog siv bubblers thiab lub sijhawm tsim nyog lub tsev tsim kom muaj lub ntsej muag tsis sib luag uas tau txias kom kaw rau qhov ua haujlwm kub hauvfore hearthchannel ua ntej kos tawm raws li txheej txheem iav. Thawj qhov kev faib tawm ntawm cov iav dej khov no tshwm sim thaum nws tseem nyob ntawm viscosity ntawm li 1000 poise; lub iav ntws los ntawm ob peb txhiab lub qhov hauv phab ntsa ntsug ntawm lub pob tig uas hu ua spinner (saib inset inFig. 2). Ntau txhiab tus ntawm cov xov ntxhib hluavtaws ua cov khoom tsim tawm tam sim ntawd ntxiv rau qhov xav kom tau zoo kawg nkaus los ntawm hluav taws kub kub sab nraud thiab / lossis muaj qhov sib hloov siab.roj kwjuas nyob ib puag ncig spinner; raug nominal kawgfiber ntau diametersthaj tsam li ntawm 4μm txog 15μm. Qhov cub hluav taws xob tuaj yeem muab lub khob xa mus rau ntau tshaj li 10 tus kiv, nrog qhov sib tshooj ntawm txhua tus spinner tau 450Kgh − 1or ntau dua. Lub tshuab kiv kiv ua hauj lwm ntawm qhov kub kub txog 1050 ° C thiab yuav tsum tivkev txhawj xeeb hooptxog ntawm 27MPa nrog tsawg distortion los yog nkag hauv qhov hnyavcorrosive ib puag ncig.
Cov fibers ua los ntawm cov txheej txheem saum toj no qee zaus siv los ua-ua tab sis feem ntau sib raug zoo togetheren masseby tau txau nrog cov dej-raws cov ntawv ntuag, feem ntau phenol – formaldehyde (PF) raws, uas tom qab ntawd qhuav thiab kho hauv qhov cub kom muab kev to taub qhovLub hauv paus fibrouskhoom siv rau pub rau handleability. Nruam slitting thiab kev kub ceev guillotining txiav cov pob txav mus rau hauv qhov tsim nyog qhov ntev rau hauv-kab compression ntim khoom li yob los yog puav. Qhov tseem ceeb ntawm kev ntim khoom ntim, rau kev lag luam hauv kev khaws cia thiab xa khoom, tuaj yeem txaus siab thaum pom tau hais tias kwv yees li 98% ntawm cov ntim ntawm ib qho raug tsis yooj yimrwb thaiv tsev battyogchaw huab cua.
Qhov tshwj xeeb fibrous wool khoom ntawm qee qhov tseem ceeb cov tshuab, uas yog siv rau cov dav hlau rwb thaiv tsev thiab pom, ua los ntawm cov txheej txheem nplaim hluav taws. Rau qhov no, moj bis uas tau tsim los ntawm lub cub tawg melting system zoo ib yam li cov lus piav qhia ua ntej yog rov qab hauv platinumbushingthiab kos rau hauv cov ntxhib ntxig lim uas ntev li 1 hli ntawm txoj kab uas tau pub rau hauv kab rov tav, muaj lub zog ntawm cov roj hlawv kom sov. Cov nplua fiber ntau tsim nyob rau hauv cov roj cua turbulent sau nyob rau ntawm cov nplais conveyor.
