Cov txheej txheem tsim khoom rau cov iav ntaub plaub muaj ib ntu txuas ntxiv: siab -kub melting, fiber ntau tsim, kho thiab teeb tsa, thiab tom qab- ua. Lub hauv paus tseem ceeb ntawm cov txheej txheem yog nyob rau hauv kev hloov cov iav raw khoom rau hauv cov khoom zoo, elongated fibers thiab tsim kom muaj lub rooj tsav xwm ruaj khov.
Thaum lub sij hawm siab -kub melting theem, raw khoom-xws li quartz xuab zeb, soda tshauv, thiab limestone-nrog rau cov iav recycled, yog tov nyob rau hauv tej proportions thiab pub rau hauv lub cub tawg, uas lawv yaj mus rau hauv ib homogeneous iav yaj ntawm kub tshaj 1,000 degree. Cov yaj tom qab ntawd dhau mus ua fiber ntau, qhov siab -ceev centrifugal spinning lossis huab cua- tshuab tshuab yog siv los kos cov iav molten rau hauv cov fibers zoo heev, ib txhij tsim cov fluffy, peb -sib nqus network qauv.
Lub thermosetting resin los yog lwm yam binder yog txau rau hauv cov fibers thaum lub sij hawm tsim cov txheej txheem kom ua tiav kev sib cog lus thawj zaug; tom qab cua sov curing stabilizes cov qauv thiab hloov cov ntaub ntawv mus rau hauv lub rooj tsavxwm nrog lub zog yuav tsum tau. Cov kauj ruam no txiav txim siab lub iav ntaub plaub lub rooj tsavxwm qhov ntom ntom, rigidity, thiab kev ruaj ntseg tag nrho.
Ncej- kev ua haujlwm suav nrog kev ua haujlwm xws li txiav kom loj, lamination nto (xws li, nrog cov ntawv txhuas lossis fiberglass daim ntaub), thiab ntim ntim. Nyob ntawm daim ntawv thov npaj, cov laug cam kuj tuaj yeem ua rau cov dej noo- pov thawj los yog kev kho mob ntxiv, ua rau lawv tsim nyog rau ntau yam kev tsim vaj tsev xws li phab ntsa rwb thaiv tsev, acoustic qab nthab panels, lossis cov khoom siv thermal rwb thaiv tsev.
