Fiberglassyog cov khoom siv iav fiber ntau uas nws lub ntsiab yog silicate. Nws yog tsim los ntawm raw cov ntaub ntawv xws li high-purity quartz xuab zeb thiab limestone los ntawm cov txheej txheem ntawm high-temperature melting, fibrillation thiab stretching. Cov iav fiber ntau muaj lub cev zoo thiab tshuaj lom neeg thiab siv dav hauvkev tsim kho, aerospace, automotive, electronics, thiab hluav taws xob fais fab.
Lub ntsiab ntawm cov iav fiber ntau yog silicate, uas lub ntsiab tseem ceeb yog silicon thiab oxygen. Silicate yog ib qho sib xyaw ua ke ntawm silicon ions thiab oxygen ions nrog cov tshuaj formula SiO2. silicon yog ib qho ntawm cov ntsiab lus ntau tshaj plaws nyob rau hauv lub ntiaj teb crust, thaum oxygen yog cov khoom muaj ntau tshaj plaws nyob rau hauv lub ntiaj teb crust. Yog li ntawd, silicates, cov khoom tseem ceeb ntawm iav fibers, muaj ntau heev nyob rau lub ntiaj teb.
Cov txheej txheem ntawm cov iav fiber ntau ua ntej yuav tsum tau siv cov khoom siv high-purity, xws li quartz xuab zeb limestone. Cov khoom siv raw no muaj ntau ntawm silicon dioxide (Si02). Thaum lub sij hawm kev npaj, cov ntaub ntawv raw yog thawj melted mus rau hauv ib tug glassy kua. Tom qab ntawd, cov kua iav yog ncab rau hauv daim ntawv fibrous los ntawm txheej txheem fibrillation. Thaum kawg, cov iav fiber ntau yog txias thiab kho kom tsim cov iav fibers.
iav fiber ntaumuaj ntau yam zoo heev. Ua ntej, nws muaj lub zog siab thiab tawv tawv uas muaj peev xwm tiv taus lub zog xws li nro, compression thiab khoov. Qhov thib ob, iav fiber ntau muaj qhov ntom ntom uas ua rau cov khoom sib sib zog nqus. Tsis tas li ntawd, iav fiber ntau kuj muaj qhov zoo corrosion kuj thiab kub tsis kam, tuaj yeem siv tau ntev hauv qhov chaw hnyav. Tsis tas li ntawd, iav fiber ntau kuj muaj cov khoom siv hluav taws xob zoo heev thiab cov khoom siv acoustic zoo, yog siv dav hauv kev lag luam.electronics thiab acoustics.
