Alkali-nruab nrab thiab alkali-dawb iav fibers yog ob hom hom ntawmCov ntaub ntawv fiberglassnrog qee qhov sib txawv hauv cov khoom thiab cov ntawv thov.
Nruab nrab alkali iav fiber ntau(E iav fiber):
Cov tshuaj lom neeg muaj pes tsawg leeg muaj cov nyiaj ntawm alkali hlau oxides, xws li sodium oxide thiab potassium oxide.
Muaj lub siab tiv thaiv mus rau qhov kub siab, feem ntau nrog kev kub siab txog 1000 ° C.
Muaj hluav taws xob rwb thaiv tsev hluav taws xob thiab corrosion tsis kam.
Feem ntau siv nyob rau hauv cov ntaub ntawv tsim kho, hluav taws xob thiab hluav taws xob Engineering, Aerospace thiab lwm thaj teb.
Alkali-Dawb iav Fiber(C iav fiber ntau):
Cov tshuaj lom neeg muaj kuab txhuas tsis muaj cov neeg hlau alkali oxides.
Nws muaj siab alkali thiab corrosion tsis kam thiab yog qhov haum rau cov alkaline ib puag ncig.
Tus nqi tsis tshua muaj kev kub hnyiab ntawm cov kub, feem ntau tuaj yeem tiv taus ntau qhov kub ntawm 700 ° C.
Nws yog tsuas yog siv hauv kev lag luam tshuaj, kev tiv thaiv ib puag ncig, nkoj thiab lwm thaj teb.
E-iav muaj ntau dua tensile muaj zog tshaj c-iav, zoo dua kev txhawb zog rau cov log.
E-iav tau ntau dua elongation, nws yuav pab txo cov fiber ntau abrasive txiav sib xws thaum lub log uas muaj kev ntxhov siab ntau.
E-iav muaj cov feem ntau ntom ntom ntom ntom, nyob ib ncig ntawm 3% tus neeg sib txuas me me hauv qhov hnyav. Ua kom muaj kev sib tsoo thiab txhim kho kev sib tsoo ntawm Englishicyog & tshwm sim ntawm kev sib tsoo lub log
E-iav muaj cov khoom muaj txiaj ntsig zoo dua, tiv thaiv dej kuj, ntxiv dag zog rau cov huab cua fiber ntau & txuas ntxiv lub caij nyoog ntawm cov log sib tsoo.

Hauv cov ntsiab lus xaus, ob qho tib siNruab Nrab-Alkali (C-iav) thiab tsis-alkali (e-iav) iav fibersmuaj lawv tus kheej cov txiaj ntsig zoo thiab cov ntawv thov. C iav muaj cov tshuaj kuj zoo heev, thaum e iav muaj cov tshuab hluav taws xob zoo nkauj thiab hluav taws xob. Nkag siab txog qhov sib txawv ntawm ob hom ntawm ob hom ntawm ob hom ntawm cov khoom tsim nyog rau cov ntawv thov tshwj xeeb thiab ua kom muaj txiaj ntsig.
