Nta ntawm Cenospheres Hollow Microspheres
Cenospheres (Expanded Mineral Materials Containing Alumina and Silica) yog ib qho khoom los ntawm cov chaw tsim hluav taws xob hluav taws xob thiab yog lub teeb yuag, inert, hollow sphere uas muaj cua lossis inert gas. Cov xim ntawm Cenosphere txawv ntawm grey mus rau yuav luag dawb thiab nws qhov ceev yog li ntawm 0.4 - 0.8 g / cm3 (0.014 - 0.029 lb./cu hauv), uas muab lawv nrog buoyancy.
Cenospheres yog siv los ua lub teeb yuag yuag hauv cov pob zeb thiab cov yas. Cov spheres yog tov nrog cov resin los ua lub teeb yuag syntactic ua npuas ncauj siv los ua cov khoom tseem ceeb rau cov sandwich panels, tooling blocks, thiab buoyancy foam. Lawv yog siv los ua cov vuas hluav taws kub-resistant refractory thiab ceramic coatings nrog tsawg thermal conductivity. Hlau-coated cenospheres yog ntxiv rau EMI shielding xim.
Nta ntawm Cenospheres (tseem hu uaHollow Microspheres):
1. Zoo fluidity: Lub hollow microbeads yog hollow ncig microspheres nrog ib tug particle txoj kab uas hla ntawm 0.2µm-400µm, thiab tus kheej kheej tus nqi yog ≥95%, uas ua rau kom lub fluidity ntawm cov khoom ntim thiab ua rau cov khoom ntim ntau haum rau kev ua.
2. Tsawg ceev: hollow microspheres muaj cov khoom ntom ntawm 0. 4g / cm3 -0. 8g / cm3. Piv nrog rau cov khoom siv hauv av feem ntau, hollow microspheres yog 30% -85% sib dua hauv qhov hnyav.
3. High Fill Rate: Hollow microspheres nyob thaj tsam tsawg kawg nkaus kom tau ntim. Vim nws cov qauv spherical, lub viscosity yog heev txo.
4. Lub zog siab: hollow microspheres tuaj yeem tiv taus 4000 kg / cm vim lawv lub plhaub tawv.
Compressive zog ntawm 3 mus rau 7000 kg / cm3.
5. Tsawg Shrinkage: Kab noj hniav kab noj hniav yog ib qho ntawm ob peb cov ntaub ntawv nyob rau hauv lub muab tub lim uas muaj peev xwm ua tau tsawg shrinkage. Lub shrinkage tus nqi ntawm ib tug loj tus naj npawb ntawm puv hollow microspheres.
6.Thaum tshav kub kub rwb thaiv tsevthiab suab rwb thaiv tsev: Lub hollow feature ua rau lub hollow microspheres muaj thermal conductivity tsawg thiab yuav siv tau rau cov rwb thaiv tsev kub thiab suab rwb thaiv tsev ntaub ntawv.
7. Muaj zog ruaj khov: hollow microspheres tuaj yeem muab ntxiv rau cov kuab tshuaj, cov tshuaj organic, dej, acids lossis cov hauv paus tsis hloov lawv cov khoom siv tshuaj.
8. Qhov kub thiab txias tsis kam: Txij li lub melting point ntawm hollow microspheres siab li 1450 ° C, nws tuaj yeem nyob ruaj khov ntawm qhov kub siab tshaj 1000 ° C.
9. Hluav taws xob rwb thaiv tsev: Siv ntau yam hluav taws xob hloov hluav taws xob, ntsuas vaj huam sib luag, thiab cov khoom ntim hluav taws xob los txhim kho rwb thaiv tsev.
10. Tus nqi qis: Tus nqi ntawm hollow microspheres yog 50% -200% qis dua li ntawm cov khoom siv microspheres.
