1. Lub teeb pom kev sib kis tau loj thiab lub permeability yog qhov zoo.
Ultra-dawb iav ntxiv rau qhov zoo ntab iav muaj tag nrho cov khoom siv tau, tab sis kuj muaj qhov ua tau zoo tshaj qhov pom, pom qhov sib kis tau zoo dua, feem ntau ntau dua 91%, plated ob npaug nyiaj tsawg-E ultra-dawb iav rau kab hlau rhuav phab ntsa, tuaj yeem nce permeability, zoo txo tus nqi ntawm cov teeb pom kev zoo.
2. Tus kheej qhov tawg ntawm ultra-dawb iav tom qab npau taws tsawg dua.
Vim tias ultra-white iav raw cov ntaub ntawv muaj tsawg dua impurities, nyob rau hauv cov khoom siv txheej txheem melting txheej txheem tswj kev ua tiav, kom lub khob dawb-iav dua li cov iav dog dig muaj ntau homogeneous muaj pes tsawg leeg, yog li txo cov kev pheej hmoo ntawm tus kheej tawg tom qab npau taws. Rau kev siv ntawm cov ntaub thaiv phab ntsa, nws muaj kev nyab xeeb dua li iav tsis tu ncua.
3, xim uniformity zoo, zoo nkauj dua.
Vim tias cov hlau cov ntsiab lus ntawm cov khoom nyoos yog ntau dua li cov iav zoo tib yam, ultra-dawb iav piv rau cov iav zoo tib yam hauv qhov pom nyob rau hauv cov ntsuab txoj kev nqus tsawg dua, kom paub meej tias cov iav zoo sib xws, kom tsis txhob muaj cov iav ntaub thaiv phab ntsa xim txawv vim los ntawm qhov teeb meem ntawm ungraceful.
4, kev nqus cua tsawg dua.
Daim iav ultra-dawb nqus tau tsawg dua tshav kub dua li ntab iav, txo cov khoom siv kub poob, ua rau nws zoo dua rau ob daim nyiaj tsawg-E hollow iav thov rau ntawm daim ntaub thaiv phab ntsa.
