Dab tsi yog cov ntaub ntawv raw ntawm fiberglass?
Fiberglassyog ib qho inorganic non{0}}cov khoom siv hlau nrog kev ua haujlwm zoo heev. Nws cov khoom tseem ceeb yog SiO2, Al2O3, CaO thiab MgO, suav txog li 90% ntawm cov khoom siv fiberglass. Nws yog tsim los ntawm cov khoom siv ntuj tsim xws li pyrophyllite, kaolin, quartz xuab zeb, limestone, dolomite, colemanite thiab magnesia pob zeb. Cov ntxhia raw cov ntaub ntawv yog hauv av rau hauv ore hmoov raws li ib tug tej yam mis nyuj, tov nrog tshuaj raw cov ntaub ntawv xws li boric acid thiab soda tshauv, thiab manufactured los ntawm high - kub melting nyob rau hauv lub pas dej ua ke kiln thiab hlau kos duab.
Los ntawm qhov kev xav ntawm tus nqi qauv ntawm fiberglass ntau lawm, cov khoom siv ntxhia xws li pyrophyllite, quartz xuab zeb, thiab limestone suav txog li 21.7% ntawm tus nqi, ntawm cov pyrophyllite suav txog ib qho - thib peb, thiab cov lej ntawm quartz xuab zeb thiab limestone kuj suav nrog qee qhov sib koom.
Pyrophyllite
Pyrophyllite yog txheej txheej aluminium silicate av nplaum ntxhia nrog 2: 1 siv lead ua qauv thiab cov tshuaj formula ntawm Al2 [Si4O10] (OH) 2. Lub hom phiaj tseem ceeb ntawm kev siv pyrophyllite hauv fiberglass yog qhia Al2O3 los hloov cov hmoov txhuas kom txo tau cov nqi thiab txhim kho cov neeg kho tshuab lub zog ntawm fiberglass. Ntawm lawv, Al2O3 pawg feem ntau zoo dua 16% -22% ntawm txhuas pyrophyllite. Siab dhau lossis qis dhau Al2O3 pawg feem ntau muaj kev cuam tshuam zoo rau cov txheej txheem tsim khoom.
Kaolin
Kaolin feem ntau muab SiO2 thiab Al2O3 hauv fiberglass ntau lawm. Fiberglass tuam txhab uas muag nyob teb chaws Europe thiab lub tebchaws United States feem ntau siv xaiv los yog siab -kaolin zoo es tsis txhob ntawm pyrophyllite li fiberglass raw khoom. kuv lub teb chaws kaolin feem ntau muab faib ua: thee-raws kaolin thiab non-coal-raws li kaolin. Ntawm lawv, SiO2 thiab Al2O3 cov ntsiab lus hauv tawv kaolin ua tau raws li cov khoom siv fiberglass. Los ntawm kev sib nqus sib nqus, flotation thiab lwm yam ntxhia ua thev naus laus zis los txo cov ntsiab lus ntawm Fe2O3 thiab TiO2 hauv cov khoom siv raw, thiab cov txheej txheem calcination kom txo tau tus nqi COD, tawv kaolin tuaj yeem siv los ua cov khoom siv fiberglass siab zoo.
Quartz xuab zeb
Quartz xuab zeb, tseem hu ua silica xuab zeb, feem ntau yog tsim los ntawm silicon dioxide thiab yog ib qho tseem ceeb raw khoom rau ze li ntawm 100 cov khoom lag luam xws li iav, hluav taws xob thiab khoom siv hluav taws xob. kuv lub teb chaws yog nplua nuj nyob rau hauv quartz mineral kev pab, xws li ntuj siv lead ua, quartz sandstone, quartzite, hmoov quartz, hlab ntsha quartz, ntuj quartz xuab zeb thiab granite pegmatite quartz.
Quartz xuab zeb tau muab faib rau ntau lub xeev thiab cheeb tsam, tab sis cov khoom siv quartz hauv kuv lub teb chaws tau tawg thiab feem ntau me me thiab nruab nrab- loj. Lub hauv paus tseem ceeb hauv tsev quartz xuab zeb tsim cov cheeb tsam yog: Donghai thiab Xinyi hauv Jiangsu, Qichun hauv Hubei, Fengyang thiab Bengbu hauv Anhui, Heyuan hauv Guangdong, Zhundong hauv Xinjiang, Yinan hauv Shandong, Lingshou hauv Hebei, thiab lwm yam.
Cov khoom siv tshuaj lom neeg
Cov ntaub ntawv raw khoom siv hauv kev tsim cov fiberglass yog tsuas yog siv rau kev npaj ntawm boric acid, soda tshauv thiab lwm yam sizing agents. Hauv kev tsim cov fiberglass, tus neeg sawv cev sizing tuaj yeem sib txuas cov fiber ntau monofilaments rau hauv cov fibers nyoos thiab zam qhov adhesion ntawm cov xov paj thaum lub sij hawm unwinding txheej txheem. Nyob rau tib lub sijhawm, nws tiv thaiv cov xov paj los ntawm kev hnav thiab tsim kua muag thaum lub sijhawm tsim khoom ntawm fiber ntau. Raws li cov txheej txheem sib txawv ntawm cov khoom siv molded, tus neeg sawv cev sizing muab cov khoom tshwj xeeb fiber ntau, xws li bundling, luv txiav, dispersion, thiab lwm yam, uas tuaj yeem txhim kho kev sib raug zoo thiab adhesion ntawm fiber ntau thiab resin substrate.
