Iav dawb ultra-dawb yog ib hom iav uas tsis muaj hlau ntau, tseem hu ua iav tsis muaj hlau ntau, iav tsis muaj xim, iav pob tshab siab, cov hlau hauv nws cov iav tsis ntau tshaj 150ppm, lub teeb kis tau ntau tshaj 92%. Raws li cov khoom siv tshiab, iav dawb ultra-dawb muaj kev cia siab dav hauv kev lag luam photovoltaic hnub ci, tsheb kim heev, tsev kim heev, tsev cog khoom kim heev thiab rooj tog kim heev.
1. Kev faib tawm ntawm cov iav dawb ultra-dawb:
Raws li cov txheej txheem sib txawv, nws tuaj yeem muab faib ua ultra-dawb calendering iav thiab ultra-dawb ntab iav.
(1) iav calendering ultra-dawb: iav ultra-dawb uas tsim los ntawm cov txheej txheem calendering tuaj yeem muab faib ua lub hnub ci ultra-dawb calendering iav (lub hnub ci substrate iav) thiab ultra-dawb pob tshab phaj iav.
Qhov zoo: ultra-dawb calendered iav muaj lub hnub ci transmittance siab, qis absorption tus nqi, siab reflectivity, siab zog, tsis kam rau lub hnub ci ultraviolet radiation yam tsis txo qis transmittance thiab lwm yam ntxwv.
(2) ultra-dawb ntab iav: ultra-dawb iav tsim los ntawm float technology yog ib hom tshiab ntawm cov iav zoo nrog zoo thiab ntau yam kev ua haujlwm. Nws muaj cov yam ntxwv ntawm glittering thiab translucent, zoo thiab elegant, thiab yog hu ua "crystal prince" ntawm tsev neeg iav.
Qhov zoo: qhov pob tshab, lub teeb xa mus, lub zog, qhov tiaj tus thiab tus nqi tawg ntawm cov iav ntab ultra-dawb zoo dua li cov iav ib txwm. Tsis tas li ntawd, nws kuj siv tau los ua cov roj teeb nyias nyias, uas pheej yig dua li cov hlwb polycrystalline silicon, thiab tseem tsim nyog rau kev tsim phab ntsa sab nraud.
Cov ntaub ntawv tseem ceeb rau kev tsim cov iav dawb ultra-dawb yog quartz xuab zeb, feldspar, dolomite, limestone, alkali hnyav, txhuas hydroxide, glauber's ntsev, sodium pyroantimonate thiab antimony trioxide.
