Cov iav microspheres, tseem hu ua Hollow Glass Microspheres (HGM), yog ib hom khoom siv uas tsis hnyav, tsis yog hlau, thiab ua haujlwm tau ntau yam. Lawv feem ntau yog ua los ntawm borosilicate thiab tsim los ntawm kev sintering kub ntawm qhov kub ntawm 700 txog 800 ℃. Nrog rau qhov loj me ntawm cov khoom me me feem ntau ntawm 10 thiab 250 micrometers thiab phab ntsa tuab ntawm 12 micrometers, cov microspheres no yog micron-sizeed thiab muaj cov yam ntxwv zoo heev xws li lub teeb yuag, lub zog siab, rwb thaiv tsev thermal, thiab tiv taus corrosion.

Cov iav microspheres muaj ntau yam kev siv vim lawv cov yam ntxwv tshwj xeeb. Lawv feem ntau siv ua cov khoom ntim rau hauv cov ntaub ntawv xws li fiberglass, qhov twg lawv tuaj yeem txo qhov hnyav, txhim kho kev ruaj khov, lub zog cuam tshuam, thiab lub zog khoov, thaum tseem txhim kho kev ruaj khov tshuaj lom neeg thiab kev rov ua dua tshiab. Tsis tas li ntawd, lawv tuaj yeem hloov cov khoom siv resin kim, txo cov nqi tsim khoom. Hauv cov ntaub ntawv sib xyaw rau kev kho, xws li putty, lawv muab qhov sib dua, muaj zog nplaum, yooj yim thov, qis shrinkage, thiab ruaj khov zoo.

Zuag qhia tag nrho, cov iav microspheres yog cov khoom siv tau ntau yam thiab muaj txiaj ntsig nrog lub peev xwm tseem ceeb rau kev txhim kho thiab siv ntxiv hauv ntau yam lag luam.
