Xav txog ib yam khoom uas ua rau koj cov khoom sib dua, muaj zog dua, thiab rwb thaiv tsev zoo dua. Qhov no yog cov lus cog tseg ntawmCov Cenospheres(Microspheres), ib yam khoom siv ua tau zoo heev uas npaj yuav hloov pauv kev tshawb fawb txog cov khoom siv thoob plaws ntau yam lag luam. Cov pob zeb khoob zoo kawg no, uas tau los ntawm cov tshauv ya, tau tsim los muab cov txiaj ntsig zoo tshaj plaws uas qhov kev ua tau zoo tseem ceeb heev.

Lub hauv paus ntawm lawv txoj haujlwm yog ib qho qauv tshwj xeeb: lub plhaub kaw, kheej kheej nrog sab hauv ze li ntawm lub tshuab nqus tsev. Qhov kev tsim qauv zoo no yog qhov chaw ntawm lawv cov txiaj ntsig peb yam: lub teeb heev (nrog qhov ceev tiag tiag ntawm 0.5-1.0 g / cm³), lub zog zoo kawg nkaus (lub zog siab ntawm 70-140 Mpa), thiab kev rwb thaiv tsev zoo tshaj plaws (kev ua kom sov ntawm 0.054-0.095 W / m · K). Lawv lub peev xwm tiv taus qhov kub txog li 1750 ° C ua rau lawv yog ib qho khoom tseem ceeb hauv cov chaw kub siab.

Ntxiv rau cov khoom tseem ceeb no, cenospheres muab cov yam ntxwv zoo dua:

• Kev Ua Tau Zoo Tshaj Plaws: Lawv ua haujlwm ua cov khoom siv me me, ua rau muaj kev tawv thiab kev hnav tsis kam hauv cov khoom sib xyaw thaum txo qhov hnyav tag nrho thiab kev siv cov khoom siv.

• Kev Ruaj Ntseg Zoo Tshaj Plaws: Nrog cov dej noo tsawg thiab cov tshuaj lom neeg tiv taus, lawv ua kom muaj kev ua tau zoo tas mus li thiab lub neej ntev hauv cov khoom kawg.

• Kev Ua Haujlwm Zoo Dua: Lawv cov duab zoo nkauj, kheej kheej txhim kho kev ntws thiab kev sib kis hauv cov kua thiab hmoov, los ntawm cov xim thiab cov txheej txheem rau cov cement thiab plastics, ua rau cov khoom tiav du thiab yooj yim dua.

• Cov Qauv Siv Tau Ntau Yam: Muaj nyob rau hauv ntau qhov ntau thiab tsawg ntawm cov khoom me me (los ntawm 10 txog 425 microns), lawv tuaj yeem tsim kho rau cov ntawv thov tshwj xeeb, los ntawm kev sau cov qhov me me hauv cov txheej txheem kom muab cov khoom loj hauv cov pob zeb sib xyaw.

Lub peev xwm ntawm daim ntawv thov yog tsis muaj qhov kawg. Hauv kev lag luam kev tsim kho, lawv tsim cov castables uas tsis hnyav, tiv taus hluav taws thiabcov pob zeb rwb thaiv tsevRau cov xim thiab cov txheej txheem, lawv txhim kho qhov opacity, durability, thiab thermal reflectance. Hauv cov yas thiab cov khoom sib xyaw, lawv txo qhov hnyav thiab shrinkage thaum txhim kho kev ruaj khov ntawm cov qauv. Ntxiv mus, lawv tseem ceeb heev rau cov teb tshwj xeeb xws li oilfield cementing (ua ib qho khoom siv sib dua) thiab aerospace (rau cov khoom sib dua, insulating composites).

Los ntawm kev koom ua ke cov cenospheres, cov chaw tsim khoom tuaj yeem ua tiav qhov tseem ceeb: tsim cov khoom tshiab uas tsis yog tsuas yog ua tau zoo thiab ruaj khov xwb tab sis kuj tseem ruaj khov dua thiab pheej yig dua. Qhib qhov tshiab ntawm kev ua tau zoo ntawm cov khoom siv.

Tiv tauj peb kom tau txais cov qauv, tus nqi thiab cov ntaub ntawv ntxiv txog cov khoom.
