Iav fiber ntau tshav kub rwb thaiv tsev hluav taws kub rwb thaiv tsev nplaim retardant non-alkali ntaub
Cov iav fiber ntau (yav tas los hu ua: iav fiber) yog ib yam khoom siv tsis muaj hlau tsis muaj hlau nrog kev ua haujlwm zoo.Nws muaj ntau yam zoo, xws li rwb thaiv tsev zoo, muaj zog kub tsis kam, zoo corrosion kuj thiab siab mechanical zog, tab sis nws qhov tsis zoo yog brittleness thiab hnav tsis zoo.Cov iav fiber ntau feem ntau yog siv los ua cov khoom siv ntxiv hauv cov ntaub ntawv sib xyaw, cov khoom siv hluav taws xob rwb thaiv tsev thiab cov ntaub ntawv thermal rwb thaiv tsev, hluav taws xob roadbed board thiab lwm yam kev lag luam hauv lub teb chaws.
1. Siv rau qhov kub thiab txias -196 ℃.kub kub 300 ℃ nruab nrab.nrog huab cua tsis kam.
2. Bon-adhesive.tsis yooj yim rau ua raws li tej yam khoom.
3. Tshuaj tiv thaiv corrosion.muaj zog acid.alkali.aqua regia thiab ntau yam organic hnyav corrosion.
4. Tsawg kev sib txhuam coefficient.yog qhov kev xaiv zoo tshaj plaws ntawm cov roj-dawb tus kheej lubrication.
5. Lub teeb transmittance ntawm 6 ~ 13%.
6. Nrog kev ua haujlwm siab rwb thaiv tsev.tiv thaiv UV.anti-static.
7. Siab siv.Nws muaj zoo mechanical zog.
8. Tshuaj tiv thaiv.
Cov iav fiber ntau yog siv rau tes muab tshuaj txhuam rau hauv cov txheej txheem, iav fiber ntau cov khoom siv daim phiaj daim ntaub yog tsuas yog nyob rau hauv lub hull, cia tank, txias ntauwd, nkoj, tsheb, tank, lub tsev cov ntaub ntawv.Cov iav fiber ntau hauv kev lag luam feem ntau yog siv rau: rwb thaiv tsev kub, tiv thaiv hluav taws, nplaim hluav taws.Cov khoom nqus cua sov ntau thaum nws hlawv los ntawm cov nplaim hluav taws thiab tuaj yeem tiv thaiv cov nplaim taws los ntawm kev, ntxiab cua.
1. Raws li cov muaj pes tsawg leeg: feem ntau alkali, alkali, siab alkali (yog los faib cov muaj pes tsawg leeg ntawm alkali hlau oxide nyob rau hauv iav fiber), ntawm chav kawm, kuj muaj kev faib tawm los ntawm lwm yam, tab sis ntau ntau yam, tsis yog ib daim ntawv teev.
2. Raws li cov txheej txheem tsim khoom: crucible drawing thiab pas dej ua ke kiln drawing.
3. Raws li ntau yam: muaj cov xov paj sib cais, cov xov paj ncaj, cov xov paj dav hlau, thiab lwm yam.
Tsis tas li ntawd, nws yog raws li ib tug fiber ntau txoj kab uas hla, TEX tooj, twist, infiltrating tus neeg saib xyuas hom kom paub qhov txawv.
Kev faib tawm ntawm cov iav fiber ntau thiab cov xov paj fiber ntau zoo sib xws, ntxiv rau cov saum toj no, kuj suav nrog: kev xaws, gram hnyav, amplitude, thiab lwm yam.
Cov iav fiber ntau thiab iav cov khoom sib txawv
Cov iav fiber ntau thiab iav cov khoom tseem ceeb sib txawv tsis loj, feem ntau yog vim cov khoom siv yuav tsum sib txawv, yog li muaj qee qhov sib txawv ntawm cov qauv.Cov ntsiab lus silica ntawm phaj iav yog li 70-75%, thiab cov ntsiab lus silica ntawm iav fiber ntau yog qis dua 60%.
Cov iav yog cov khoom siv tsis zoo tom qab kub kub yaj (siab dua 800 degrees, iav hauv tsev feem ntau yog yaj ntawm 1100 degrees)., hauv qab qhov ntsuas kub ntawm qhov muag, tsis muaj tshuaj hloov pauv yuav tshwm sim.Tshaj qhov kub ntawm qhov muag muag, nws tsuas yog softens, melts los yog decomposes, tsis muaj combustion.
Cov iav fiber ntau yog cov iav rub rau hauv cov iav zoo heev, lub sij hawm no cov iav hlau muaj qhov muag zoo heev.Cov iav filament yog spun rau hauv xov paj thiab tom qab ntawd dhau los ntawm ib lub loom los ua cov ntaub fiberglass.Vim hais tias cov iav filament zoo heev, qhov chaw saum npoo ntawm ib chav tsev loj heev, yog li qhov kub tsis kam yog txo.Ib yam li lub tswm ciab tuaj yeem yaj zoo tooj liab hlau.
Tab sis iav tsis hlawv.Lub combustion uas peb tuaj yeem pom yog qhov tseeb los txhim kho kev ua haujlwm ntawm daim ntaub fiberglass, thiab qhov chaw ntawm daim ntaub fiberglass coated nrog cov khoom siv cob, lossis txuas nrog impurities.Ntshiab iav fiber ntau daim ntaub los yog coated nrog ib co kub resistant txheej, nws yuav ua tau los ntawm refractory khaub ncaws, refractory hnab looj tes, refractory pam khoom.Txawm li cas los xij, yog tias nws nkag mus rau hauv daim tawv nqaij ncaj qha, cov fibers tawg yuav ua rau tawv nqaij ntau dua thiab ua rau khaus.
Cov pa iav fiber ntau monofilm txoj kab uas hla hauv ntau dua 9-13 microns, qis dua 6 microns ntawm iav fiber ntau ntab, tuaj yeem ncaj qha mus rau hauv lub ntsws raj, tuaj yeem ua rau muaj kab mob ua pa, yog li them nyiaj tshwj xeeb rau, 6 microns hauv qab no feem ntau yog imported.Cov qhov ncauj qhov ntswg kws tshaj lij yuav tsum tau hnav thaum lub sijhawm ua haujlwm ntau lawm.Yog tias koj raug nws ntau zaus, nws tuaj yeem nqus tau rau hauv koj lub ntsws thiab ua rau pneumoconiosis.
Yog tias lub cev kov cov iav fiber ntau, daim tawv nqaij tsis zoo yuav ua xua yuav khaus, tab sis feem ntau yuav tsis muaj kev phom sij loj, daim tawv nqaij tsis zoo yuav yog ib lub hnab me me, uas yog qhov tshwm sim tsis haum.
Yog tias nws nyuaj rau tshem tawm ntawm cov khaub ncaws, tuav nws ob peb zaug hauv qhov chaw cua.Tom qab ntxuav thiab ziab, nws yooj yim dua tshem tawm los ntawm kev ntaus nws nrog ib ceg.
