Alkali-neutral thiab alkali-dawb iav fibers yog ob hom ntawmcov ntaub ntawv fiberglassnrog qee qhov sib txawv ntawm cov khoom thiab kev siv.
Nruab nrab alkali iav fiber ntau(E iav fiber ntau):
Cov tshuaj muaj pes tsawg leeg muaj qhov nruab nrab ntawm alkali hlau oxides, xws li sodium oxide thiab potassium oxide.
Nws muaj kev tiv thaiv siab rau qhov kub thiab txias, feem ntau tiv taus kub txog 1000 ° C.
Nws muaj cov hluav taws xob rwb thaiv tsev zoo thiab corrosion kuj.
Feem ntau siv hauv cov khoom siv, hluav taws xob thiab hluav taws xob engineering, aerospace thiab lwm yam haujlwm.
Alkali-dawb iav Fiber(C iav Fiber):
Cov tshuaj muaj pes tsawg leeg tsis muaj alkali hlau oxides.
Nws muaj siab alkali thiab corrosion kuj thiab yog haum rau alkaline ib puag ncig.
Kev tiv thaiv qis ntawm qhov kub thiab txias, feem ntau tuaj yeem tiv taus qhov kub thiab txias li ntawm 700 ° C.
Nws yog tsuas yog siv hauv kev lag luam tshuaj, kev tiv thaiv ib puag ncig, nkoj thiab lwm yam kev lag luam.
E-iav muaj zog tensile ntau dua li C-iav, zoo dua ntxiv rau cov log sib tsoo.
E-iav muaj ntau dua elongation, nws yuav pab txo cov iav fiber ntau abrasive txiav piv thaum lub sij hawm tsim cov txheej txheem ntawm kev sib tsoo log thaum nws nyob rau hauv ib tug siab kev nyuaj siab.
E-iav muaj qhov ntim ntau dua, nyob ib ncig ntawm 3% ntim me me hauv tib qhov hnyav. nce cov tshuaj abrasive thiab txhim kho kev sib tsoo ua haujlwm & qhov tshwm sim ntawm kev sib tsoo log
E-iav muaj cov khoom zoo dua ntawm cov av noo tsis kam, dej tsis kam & kev laus ua haujlwm, ntxiv dag zog rau huab cua ntawm fiberglass discs & txuas ntxiv lub sijhawm lav ntawm kev sib tsoo log.

Hauv cov ntsiab lus, ob qho tib simedium-alkali (C-iav) thiab tsis-alkali (E-iav) iav fibersmuaj lawv tus kheej tshwj xeeb zoo thiab kev siv. C iav muaj cov tshuaj tiv thaiv zoo heev, thaum E iav muaj cov khoom zoo heev thiab hluav taws xob rwb thaiv tsev. Nkag siab txog qhov sib txawv ntawm ob hom fiberglass no yog qhov tseem ceeb rau kev xaiv cov khoom tsim nyog tshaj plaws rau ib daim ntawv thov tshwj xeeb, ua kom pom kev ua haujlwm zoo thiab ua haujlwm ntev.
