Cov cenospheres uas muaj kev txaus siab rau teeb meem aerospace composite materials

Cenospheres uas nyab xeeb rau qhov ceev siab yog cov khoom siv inorganic hollow spherical uas muaj qhov zoo heev thiab tau ua los ntawm fly ash zoo heev thiab tau ua los ntawm kev sib txuas thiab kho kom zoo heev. Lawv muaj qhov chaw ntsuas uas txaus siab thiab muaj qhov ntsuas txaus siab heev rau 1200℃, thiab muaj qhov ntsuas ntau tshaj 0.4–0.6 g/cm³ thiab muaj kev nyab xeeb heev rau kev puas.

Cov lus qhia no muaj kev sib thaj ntau dua rau epoxy, phenolic, thiab cov lus qhia uas muaj carbon fiber-reinforced composites, tshem cov khoom sib xyaw rau hauv cov khoom sib xyaw kom tsawg dua, thiab txhawb cov khoom sib xyaw kom muaj kev nyab xeeb ntawm qhov ceev, kev tswj hwm qhov loj, thiab kev tswj hwm rau kev puas tsuaj—txhais tau tias yog qhov txaus siab rau cov khoom sib xyaw rau aerospace thiab cov khoom sib xyaw hauv tsev kho mob uas muaj kev puas tsuaj ntau. Cov lus qhia muaj qhov loj sib xyaw (40–120 mesh, tuaj yeem suav raws li kev xav) txhawb kom cov lus qhia sib xyaw hauv cov khoom sib xyaw kom zoo, tshem cov qhov tawg thiab txhawb kom cov khoom sib xyaw muaj kev nyab xeeb, uas yog qhov txaus siab rau kev ua haujlwm zoo hauv qhov chaw uas muaj kev puas tsuaj ntau.

Lub tswv yim no yog qhov tswv yim tshiab uas muaj kev nyab xeeb rau lub ntiaj teb thiab muaj kev pab tau zoo dua rau cov khoom sib xyaw uas muaj qhov loj tsawg dua, thiab nws sib koo nrog cov standards rau aerospace industry (ISO 9001/ROHS) thiab txhawb kev pab rau kev tsim cov khoom uas muaj kev pab tau zoo rau cov khoom sib xyaw thiab muaj kev pab tau zoo rau kev ua haujlwm. Yog qhov zoo rau cov kev siv uas xav tau kev sib npog ntawm qhov loj tsawg, kev nyab xeeb rau qhov ceev ntau, thiab kev pab tau zoo rau cov khoom sib xyaw—los ntawm cov khoom sib xyaw rau aerospace mus rau cov khoom sib xyaw tshiab hauv tsev kho mob.
