Glassfiber&Fiberglass
Artificial inorganic fiber ntau. Siv cov khoom siv ntuj xws li quartz xuab zeb, limestone, tus kheej-marble, kaolin, pyropyrol, thiab lwm yam., nrog rau lwm cov ntaub ntawv raw xws li dej qab zib, stretch acid (tseem siv tau kom muaj alkali, ncab ntuj ore hloov), yaj rau hauv iav. , nyob rau hauv lub xeev molten los ntawm sab nraud quab yuam rub, tshuab lossis cam khwb cia rau hauv cov ntaub ntawv fiber ntau zoo. Raws li nws muaj pes tsawg leeg thiab cov khoom, nws tuaj yeem muab faib ua alkali dawb iav fiber ntau (xws li cov iav tsis-stretched), nruab nrab alkali iav fiber ntau, siab alkali iav fiber ntau thiab tshwj xeeb iav fiber ntau; Raws li nws daim ntawv, nws tuaj yeem muab faib ua cov iav fiber ntau txuas ntxiv, ruaj khov ntev iav fiber ntau thiab iav ntaub plaub; Raws li txoj kev tsim khoom, nws tau muab faib ua ob pawg: ib qho yog ua kom cov iav molten ncaj qha mus rau hauv fiber ntau, lwm qhov yog ua kom cov iav molten rau hauv pob, pas nrig lossis cov khoom thaiv, thiab tom qab ntawd siv los ua raw khoom, remelting. rau hauv fiber ntau nrog ntau hom kev siv cua sov. Cov yam ntxwv ntawm cov iav fiber ntau yog: tsis-combustible, corrosion kuj, kub tsis kam, me me noo noo nqus, me elongation, siab tensile zog, zoo tshuaj stability, zoo hluav taws xob rwb thaiv tsev thiab rwb thaiv tsev kev ua tau zoo, tsis yooj yim thiab folding kuj. Vim yog cov iav sib txawv, ib qho ntawm qhov kev ua tau zoo tuaj yeem ua tau zoo dua. Nws tuaj yeem ua rau ntau hom khoom, xws li xov paj, ntaub plaub, ntaub, siv, puag ncig daim ntaub yooj yim, nyias nyias, xav, phaj, raj plhaub thiab lwm yam. Nws tuaj yeem siv los ua cov khoom siv hluav taws xob rwb thaiv tsev, cov khoom siv lim dej, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam. ntawm cov ntaub ntawv sib xyaw, xws li iav fiber reinforced thermoset yas (FRP), iav fiber reinforced thermoplastic thiab cov khoom siv roj hmab ntxiv, iav fiber reinforced inorganic cementing cov khoom xws li reinforced gypsum thiab cement, thiab lwm yam.; Kuj tseem tuaj yeem siv cov txheej txheem ntawm cov txheej txheem organic los txhim kho nws qhov yooj yim, ua ntau yam khoom muag xws li ntim cov ntaub, qhov rai screen, kab hlau rhuav, phab ntsa ntaub, tsev pheeb suab ntaub, cov ntaub ntawv hauv tsev thiab cov khoom siv tiv thaiv tshwj xeeb. Cov khoom no tau siv dav hauv kev lag luam, kev ua liaj ua teb, kev tsim kho thiab pej xeem. Thiab vim tias nws muaj qee yam khoom zoo heev uas lwm cov ntaub ntawv tsis muaj, nws tau dhau los ua cov khoom tseem ceeb hauv kev lag luam tub rog.
Ciav fiber ntau
Ib chav kawm loj ntawm cov ntaub ntawv fiberglass. Hais txog molten kub viscous iav kua los ntawm turbulent qhov outflow, yog rub mus rau infinite ntev ntawm iav fiber los ntawm sab nraud quab yuam. Nruam iav fiber ntau muaj thickness, nws siv yog txawv. Feem ntau, txoj kab uas hla ntawm 3-9 m fiber ntau woven rau hauv ntau yam khoom siv textile, xws li ntaub, siv, casing, thiab lwm yam, vim hais tias feem ntau los ntawm textile ua, thiaj li hu ua textile iav fiber ntau; Cov fibers uas muaj ib txoj kab uas hla ntawm 10-24 m tau siv los ua cov ntaub ntawv nruj xws li tsis muaj twist roving, tsis muaj twist coarse gauze, luv luv-cut raw silk, thiab luv-cut raw silk. Yog li nws tseem hu ua txhim kho iav fiber ntau.
Siav fiber ntau
Ib chav kawm loj ntawm cov ntaub ntawv fiberglass. Nws yog ib lub iav fiber ntau ntev, kuj hu ua paj rwb ntev. Muaj ntau txoj kev tsim khoom, xws li tshuab thiab dov. Qhov ntev ntawm qhov ruaj khov ntev fiber ntau tsis sib xws. Nws tuaj yeem ua rau hauv cov xov paj ntaub plaub thiab ua tiav rau hauv cov ntaub, tuaj yeem ua rau nyias nyias, lossis ua tiav rau hauv cov khoom, siv los ua cov khoom siv dej tsis zoo, cov khoom siv lim dej thiab cov khoom siv rwb thaiv tsev.
E-CR iav fiber ntau
Nws yog ib hom iav fiber ntau uas tsis muaj B2, O3 thiab F2. Txij li xyoo 1970, vim muaj kev mloog zoo rau ib puag ncig thiab txhawm rau txhim kho cov tshuaj lom neeg thiab cov khoom siv ntawm iav, ntau qhov kev hloov pauv tau ua rau cov iav E: Los ntawm kev txo cov ntsiab lus ntawm B2 O3 thiab F2, TiO2, ZnO, SrO. thiab Li2 O oxides tau ntxiv thiab qhia, E-CR iav fiber ntau, tsis muaj iav fiber ntau, tsis muaj iav fiber ntau thiab Advantex iav fiber ntau tau tshwm sim. Hom fiber ntau no muaj cov hluav taws xob zoo hluav taws xob thiab tshuaj lom neeg ruaj khov, thaum txhim kho cov khoom siv hluav taws xob ntawm cov fiber ntau, ua rau nws zoo rau ib puag ncig.
M iav fiber ntau
Kuj hu ua siab modulus iav fiber ntau, hu ua siab modulus iav fiber ntau. Lub elastic modulus thiab tensile lub zog ntawm cov yas reinforced ua nrog nws yog ntau tshaj 30 feem pua siab dua cov uas ua nrog alkali-dawb fibers thiab 5 feem pua -30 feem pua siab dua. Feem ntau ntawm cov iav no tau ntxiv rau magnesium aluminium silicon system iav, qee cov oxides xws li BeO, ZrO2, TiO2, tsis tshua muaj ntiaj teb oxides thiab lwm yam khoom los txhim kho cov elastic modulus thiab lub cev thiab tshuaj lom neeg. Ntau dua melting kub thiab crystallization sab sauv txwv kub tshaj alkal-dawb thiab nruab nrab-alkali iav, crystallization ceev ceev, yog li cov fiber ntau ua kub yog siab dua. Nws yog tsuas yog siv rau iav fiber reinforced yas khoom nrog siab elastic modulus thiab lub teb chaws tiv thaiv science.
