Boehmite Alumina

Zibo Xiangrun thiab Shandong Bairui pawg tsim aluminas thiab boehmites muab tau los ntawm txhuas alkoxides. Peb aluminas thiab boehmites muaj tshuaj purity thiab dispersibility. Tseem ceeb cov khoom xws li pore ntim, particle loj thiab tej qhov chaw deg yuav tau kho. Vim lawv muaj peev xwm ntawm cov khoom, cov aluminas thiab boehmites muaj ntau tshaj 30 xyoo pom lawv txoj kev mus rau ntau hom kev siv ntau yam, xws li cov kev txhawb zog, coatings, polymer additives, pleev xim pleev xim, cov roj ntsha thiab kua txiv hmab txiv ntoo.

Synonyms

pob alumina, AlO (OH), colloidal boehmite, tshuaj yaj, boehmite dispersions, nano-tsuas boehmite, dispersible boehmite, aluminium oxide

Dispersible boehmites yog siv rau hauv daim ntaub ntawv xws li cov kua nplaum ci, cov phau ntawv pov thawj rau cov tshuaj nplaum, cov khoom tsis haum, kev tswj ntawm qhov dej, qhov kev txhuam thiab pleev xim pleev xim.

Lwm cov kev siv ntau dua rau kev siv cov hmoov pob hmoov alumina nrog rau txheej ntim thiab cov coag tshuaj polymer.

Cov tshuaj hmoov alumina, uas yog nano-xim nyob rau lub sij hawm faib, muaj kev sib tov sib xyaw ua ke, zoo sib xws, thiab ua kom zoo tshaj plaws uas ua rau lawv siv cov ntaub ntawv zoo rau kev siv cov ntaub ntawv colloidal. Tshuaj khov dispelible yog siv rau hauv cov ntaub ntawv xws li cov kua nplaum ci, cov phau ntawv pov thawj rau cov kab xo, cov khoom tsis haum, kev tswj kev tswj hauv rheology, kev txhuam thiab cov txheej txheem pleev xim. Lwm cov kev siv ntau dua rau kev siv cov hmoov pob hmoov alumina no muaj xws li ntim txheej thiab cov tshuaj ntxiv rau polymer.
