Hāʻawi ʻo Junda i kahi kōpili ākea o nā mea boehmite
Hoʻokaʻawale mua ʻia nā mea e ka dispersibility.Junda e hāʻawi i nā huahana mai ka dispersible loa, ka paʻa paʻa, PB950, a hiki i ka liʻiliʻi liʻiliʻi, extrusion grade, PB250A a me PB150.A loaʻa iā ia nā ʻano o ka maʻemaʻe kiʻekiʻe, ka hāʻawi ʻana i ka nui o nā ʻāpana, maikaʻi dispersion. , Paʻa pūʻulu maikaʻi, a me nā mea ʻē aʻe, hiki ke hoʻohana nui ʻia i ke ahi retardant, ka uhi ʻana o ka diaphragm ikehu hou, ka pā lithium ka uhi ʻana o ka pepa electrode, ka pā keleawe i uhi ʻia, polishing abrasive a me nā māla ʻē aʻe.
Loaʻa kēlā me kēia papa o nā mea i loko o kahi ākea o nā kī maʻamau, e wehewehe ana i nā waiwai e like me ka nui o ka kristal, ka nui o ka pore, a me ka nui o ka particle. noi kūikawā.
ʻO kēia pūʻulu o nā huahana he liʻiliʻi liʻiliʻi liʻiliʻi, leo pore kiʻekiʻe, kahi ākea kikoʻī nui, hoʻoheheʻe gel maikaʻi, hoʻomaʻemaʻe kristal kiʻekiʻe, haʻahaʻa haʻahaʻa haumia. Loaʻa iā ia nā hiʻohiʻona o ka gel thixotropic.
1, hoʻohana ʻia e like me ka petrochemical a me ka hoʻomaʻemaʻe catalyst ʻoihana binder a me ka molecular sieve synthesis o ke kumu alumini.
Hoʻohana nui ʻia ʻo Pseudo-boehmite ma ke ʻano he binder no ka catalytic cracking catalyst. ʻAʻole hiki i ka pseudo-boehmite ke hoʻomaikaʻi wale i ka ikaika o ka catalyst, akā hoʻoponopono pū i ka puʻupuʻu pore nui o ka catalyst, hoʻomaikaʻi i ka thermal a me ka hydrothermal stability o ka catalyst, hoʻoponopono i ka density o ka waikawa ikaika o ka catalyst, a hoʻomaikaʻi i ka hana catalytic.
2. Hoʻohana ʻia e like me ke kākoʻo catalyst
Hoʻohana nui ʻia ʻo Boehmite ma ke ʻano he kākoʻo catalyst no ke kemika, hoʻomaʻemaʻe aila a me nā hopena petrochemical. ʻO nā hiʻohiʻona maʻamau ke kākoʻo hydrorefining catalyst, reforming catalyst support, methanation catalyst support, a pēlā aku.
