Lub pob zeb drift bead yog ib hom pob zeb fly ash hollow uas ntab tau saum dej. Nws yog xim grey dawb, nrog cov phab ntsa nyias thiab khoob, thiab hnyav heev. Qhov hnyav ntawm lub pob zeb yog 720kg/m3 (hnyav), 418.8kg/m3 (sib dua), thiab qhov loj ntawm cov khoom me me yog li 0.1 hli. Qhov saum npoo yog kaw thiab du, nrog cov thermal conductivity qis thiab tiv taus hluav taws ntawm ≥ 1610 ℃. Nws yog cov khoom siv refractory zoo heev, siv dav hauv kev tsim cov castables sib dua thiab kev khawb roj. Cov tshuaj lom neeg ntawm lub pob zeb floating feem ntau yog silicon dioxide thiab txhuas oxide. Nws muaj cov yam ntxwv ntawm cov khoom me me, khoob, hnyav sib dua, muaj zog siab, tiv taus hnav, tiv taus kub siab, rwb thaiv tsev thermal, rwb thaiv tsev thiab hluav taws kub tsis kam. Nws yog ib qho ntawm cov khoom siv raw siv dav hauv kev lag luam tiv taus hluav taws.

Lub tshuab tsim cov hlaws dai ntab: Cov chaw tsim hluav taws xob uas siv thee feem ntau zom thee ua hmoov thee thiab txau rau hauv lub cub tawg ntawm lub boiler tsim hluav taws xob, ua rau nws raug ncua thiab hlawv. Feem ntau ntawm cov khoom siv hluav taws xob ntawm thee (carbon thiab organic matter) raug hlawv, thaum cov khoom siv tsis hluav taws xob ntawm av nplaum (silicon, txhuas, hlau, magnesium, thiab lwm yam) pib yaj ntawm qhov kub siab ntawm 1300 degrees Celsius hauv lub cub tawg, tsim lub cev sib xyaw ua ke ntawm quartz iav thiab mullite.

Qhov chaw ntawm cov tshauv ya ntab ntab
Cov hlaws dai uas ntab yog hais txog cov iav me me uas muaj qhov ceev tsawg dua li dej hauv cov tshauv ya, uas yog ib hom hlaws dai zoo li cov hmoov tshauv ya thiab tau muab lub npe raws li lawv lub peev xwm ntab saum dej. Nws lub sijhawm tsim yog thaum cov hmoov thee raug hlawv hauv lub boiler ntawm lub chaw ua hluav taws xob thermal, cov khoom siv av nplaum yaj mus ua cov tee dej me me, uas tig ntawm qhov ceev ceev nyob rau hauv qhov kev ua ntawm cua kub turbulent hauv lub cub tawg, tsim ib lub voj voog silicon txhuas. Cov pa roj xws li nitrogen, hydrogen, thiab carbon dioxide tsim los ntawm kev sib xyaw thiab kev tawg sai sai nthuav dav hauv lub voj voog silicon txhuas kub siab, tsim cov npuas iav khoob hauv qab qhov nro ntawm qhov chaw. Tom qab ntawd lawv nkag mus rau hauv lub qhov cub kom txias sai thiab tawv, tsim cov iav me me uas muaj qhov nqus tsev siab, uas yog cov hlaws dai ntab.

Cov hlaws dai uas ntab los ntawm cov tshauv ya yog los ntawm cov tshauv ya thiab muaj ntau yam zoo li cov tshauv ya. Txawm li cas los xij, vim nws cov xwm txheej tsim tshwj xeeb, lawv muaj kev ua tau zoo dua li cov tshauv ya. Lawv yog cov khoom siv hmoov tshiab uas tsis yog hlau thiab muaj ntau yam thiab paub tias yog cov khoom siv ntawm lub hnub nyoog chaw.
