Tshwj xeeb Pseudo Boehmite

P-DF-10 P-DF-10 yog ib nrab ceev, pore loj loj pseudo-boehmite yam khoom, uas tus ua cim npaws purity, pore loj ntim, teeb pore loj tis thiab kua qaub-soluble zoo. Rau qhov loj p

Khoom specifications:

Yog koj kam lag luam wholesale, zoo siab heev thiab check tshwj xeeb pseudo boehmite los ntawm ib tus naas ej Suav teb tsawg sodium pseudo boehmite, tsis ntom pseudo boehmite manufacturers, CHALCO yog ib txwm thaum koj qhov kev pab.

P-DF-10

P-DF-10 yog ib nrab ceev, pore loj loj pseudo-boehmite yam khoom, uas tus ua cim npaws purity, pore loj ntim, teeb pore loj tis thiab kua qaub-soluble zoo.

Lub ntim pore loj, ib cheeb tsam deg, thermal stability, P-DF-10 muaj formability zoo siab ua tau thiab yam ntxwv kuj coj zoo, uas nyob nrog siv hauv hydrocracking, hydrotreating, hydrogenation refining catalyst

H-B-90

H-B-90 yog ib β-Al (OH) 3 cov hmoov uas ua los ntawm siab liquidity kev tshwj xeeb. Nws yog insoluble ua kua qaub. Raws li catalyst Cheebtsam, H-B-90 muaj cov khoom uas tsawg dua nws cov kua qaub chaw dhia ceev.

Tom qab kev txoj kev molding, nws yuav ua tau los ua ntau daim yeev bar pob thiab zoo li tus tshwj xeeb. H-B-90 lug siv hauv siab yam kua qaub chaw catalyst teb.
