Cov ntaub ntawv raw tseem siv rau hauv kev tsim coviav yasXws li cov hauv qab no:
Quartz xuab zeb:Quartz xuab zeb yog ib qho ntawm cov ntaub ntawv raw tseem ceeb hauv kev tsim cov fiberglass, muab cov silica uas yog cov khoom siv tseem ceeb hauv fiberglass.
Alumina:Alumina tseem yog cov khoom siv tseem ceeb rau cov khoom siv tseem ceeb rau cov fiberglass thiab yog siv los kho cov tshuaj lom neeg thiab cov khoom ntawm fiberglass.
Foliated paraffin:Foliated paraffin plays Lub luag haujlwm ntawm fluxing thiab txo qis lub suab kub me me hauv kev tsim coviav yas, uas pab ua kom tsim cov kev sib dhos cov fiberglass.
Limestone, dolomite:Cov ntaub ntawv raw no feem ntau yog siv los kho cov ntsiab lus ntawm alkali hlau oxides, xws li magrium oxide, hauv fiberglass, yog li cuam tshuam rau lawv cov khoom siv thiab lub cev.
Boric acid, dej tshauv so, manganese, fluorite:Cov ntaub ntawv raw hauv kev tsim cov fiberglass ua si lub luag haujlwm ntawm flux, tswj cov muaj pes tsawg leeg thiab cov khoom ntawm iav. Boric acid tuaj yeem nce cov tshav kub tawm thiab tshuaj lom neeg ruaj khov ntawmiav yas, soda tshauv thiab mannite pab kom txo cov melting kub, tshuaj fluorite tuaj yeem txhim kho cov kev hloov pauv thiab ua kom cov iav tshiab.
Ib qho ntxiv, nyob ntawm hom thiab kev siv cov fiberglass, lwm cov ntaub ntawv raw tshwj xeeb lossis cov tshuaj ntxiv yuav tsum tau ntxiv kom tau raws li cov cai ua tau zoo. Piv txwv li, nyob rau hauv thiaj li tsim alkali-dawb fiberglass, cov ntsiab lus ntawm alkali hlau oxides nyob rau hauv cov khoom siv raw tau yuav nruj me ntsis tswj tau; Txhawm rau tsim cov fiberglass, nws yuav tsim nyog los ntxiv kev txhawb nqa cov neeg sawv cev lossis hloov cov kev sib piv ntawm cov khoom raw.
Zuag qhia tag nrho, muaj ntau cov khoom siv raw siv rau hauv kev tsim cov fiberglass, txhua tus yog ib qho kev txiav txim siab cov tshuaj muaj pes tsawg leeg, cov khoom siv lub cev, thiab siv cov fiberglass.
