Drift hlaws yog ib hom ya tshauv hollow pob uas tuaj yeem ntab rau saum npoo dej.Nws yog grey dawb nyob rau hauv cov xim, nrog nyias thiab hollow phab ntsa, thiab ib tug heev lub teeb yuag.Chav tsev hnyav yog 720kg / m3 (hnyav), 418.8kg / m3 (lub teeb), thiab particle loj yog li 0.1 hli.Qhov saum npoo yog kaw thiab du, nrog thermal conductivity tsawg thiab hluav taws kub tsis kam ntawm ≥ 1610 ℃.Nws yog qhov zoo tshaj plaws kub khaws cov khoom siv refractory, dav siv hauv kev tsim cov castables thiab roj drilling.Cov tshuaj muaj pes tsawg leeg ntawm cov hlaws ntab yog feem ntau silicon dioxide thiab aluminium oxide.Nws muaj cov yam ntxwv ntawm cov khoom zoo, hollow, lub teeb yuag, siab zog, hnav tsis kam, kub tsis kam, thermal rwb thaiv tsev, rwb thaiv tsev thiab nplaim taws retardancy.Nws yog ib qho ntawm cov khoom siv raw siv dav hauv kev lag luam hluav taws kub.

Cov txheej txheem tsim cov hlaws dai: Cov chaw tsim hluav taws xob hluav taws xob feem ntau zom cov thee rau hauv cov hmoov nplej thiab tshuaj tsuag rau hauv lub qhov cub hluav taws xob ntawm lub tshuab hluav taws xob, uas tso cai rau nws raug tshem tawm thiab hlawv.Feem ntau ntawm cov khoom siv hluav taws xob ntawm cov thee (carbon thiab organic teeb meem) raug hlawv, thaum cov khoom tsis sib xyaw ntawm cov av nplaum (silicon, aluminium, hlau, magnesium, thiab lwm yam) pib yaj ntawm qhov kub ntawm 1300 degrees Celsius hauv qhov cub, tsim ib tug ntxeem tau symbiotic lub cev ntawm quartz iav thiab mullite.

Qhov chaw ntawm ya tshauv ntab hlaws
Fly tshauv ntab hlaws dai yog hais txog qhov khoob iav microspheres nrog qhov ntom ntom tsawg dua dej hauv cov tshauv ya, uas yog hom ya tshauv hlaws zoo li cov khoom thiab muaj npe tom qab lawv muaj peev xwm ntab rau hauv dej.Nws tiam yog thaum cov hmoov av hlawv nyob rau hauv lub boiler ntawm ib tug thermal fais fab nroj tsuag, cov av nplaum cov ntaub ntawv melts mus rau hauv micro droplets, uas tig ntawm kev kub ceev nyob rau hauv qhov kev txiav txim ntawm turbulent cua kub nyob rau hauv lub cub tawg, tsim ib puag ncig silicon txhuas sphere.Gases xws li nitrogen, hydrogen, thiab carbon dioxide tsim los ntawm combustion thiab cracking tshwm sim sai heev nthuav nyob rau hauv lub molten high-temperature silicon aluminium sphere, tsim hollow iav npuas nyob rau hauv qhov chaw nro.Tom qab ntawd lawv nkag mus rau lub flue kom txias sai thiab tawv, tsim lub tshuab nqus tsev iav hollow microspheres, uas yog ya tshauv ntab hlaws.

Fly tshauv ntab hlaws los ntawm ya tshauv thiab muaj ntau yam khoom ntawm ya tshauv.Txawm li cas los xij, vim nws qhov kev tsim tshwj xeeb, lawv muaj kev ua tau zoo dua piv rau ya tshauv.Lawv yog ib lub teeb yuag uas tsis yog-hlau multifunctional tshiab cov khoom siv hmoov thiab paub tias yog cov ntaub ntawv ntawm qhov chaw hnub nyoog.
