E like me ka mea nui o ka lepo diatom, hoʻohana nui ka honua diatomaceous i kona ʻano microporous e lawe mai i ka hiki adsorption o nā kinoea macromolecular e like me benzene, formaldehyde, a me nā mea ʻē aʻe. I kēia manawa, ʻo nā ʻano hana maʻamau o ka hoʻoili ʻana i ka diatomite ma ka mākeke ka mea nui i ka ʻala a me ka calcination. He kiʻekiʻe nā koi o ka hoʻomoʻa ʻana, lohi ka wikiwiki, haʻahaʻa ka hoʻopuka, a he kiʻekiʻe ke kumukūʻai, ʻoiai he haʻahaʻa nā koi calcination, wikiwiki ka wikiwiki, a ʻoi aku ka haʻahaʻa o ke kumukūʻai.

1. ʻO ka mea i kapa ʻia ʻo ka ʻala ʻana e pili ana i ka mālama pono ʻana i ka mahana ma kahi o 500 degere Celsius, e hoʻokiʻekiʻe mālie i ka mahana o ka honua diatomaceous, a me ka ʻai ʻana i ka wikiwiki mau no nā hola 2, hiki ke mālama i ka hapa nui o ka pore pono a me ka adsorption maikaʻi o ka honua diatomaceous, a ua lohi.piha loa, a ua kiʻekiʻe ka keʻokeʻo a ua like nā ʻāpana.

2. ʻO ka Calcining e pili ana i ka hoʻohui ʻana i ka honua diatomaceous i ka co-solvent a me ka hoʻomehana ʻana i loko o ka umu ahi ma kahi wela kiʻekiʻe o 900 a 1150 degere no 10 mau minuke a 30 mau minuke. Hoʻoheheʻe koke ka co-solvent a hoʻopaʻa me ka honua diatomaceous. Hiki ke hana ʻia ka calcining me ka liʻiliʻi o ka manawa a me ke kumu kūʻai haʻahaʻa. Eia nō naʻe, no ka mea he kiʻekiʻe loa ka mahana a paʻakikī hoʻi i ka mālama ʻana, maʻalahi ka sinter a me ka pellet i ka diatomite, pono e hoʻoheheʻe ʻia a wāwahi ʻia i ka fineness i makemake ʻia, e hōʻino i ka lua i nā pores ma ka ʻili o ka diatomite. I ka hoʻoheheʻe ʻana o ka cosolvent a pili i ka ʻili o ka honua diatomaceous, ua paʻa nā pores o ka honua diatomaceous, a ua hoʻemi ʻia ka ʻāpana kiko o ka honua diatomaceous. Eia kekahi, ʻo ke kiʻekiʻe kiʻekiʻe e like me 1100 e hoʻoheheʻe maʻalahi a nalowale i nā micropores o ka honua diatomaceous, ua hoʻopau loa ʻia ka micropore structure o ke kino diatomaceous, ua crystallized a hoʻoheheʻe ʻia kekahi o nā pā pore, a ua komo ka nui o ka honua diatomaceous.

Ua hōʻike ka hoʻokolohua o ka lepo diatom ua calcined 100g o ka honua diatomaceous ma 500 degere Celsius no 2 mau hola a ua hoʻohui ʻia ka 5% co-solvent, a laila ua calcined ka ʻili ma 900 ° a me 1100 °, kēlā me kēia, a ʻike ʻia ka ʻili ma lalo o kahi microscope electron scanning.

Ma hope o ka calcination ma 500 °, ua piha loa ka ʻili o ka honua diatomaceous, a ʻaʻohe hōʻailona o ka hāʻule ʻana a i ʻole ka hui ʻana o nā pores, e hōʻike ana he kiʻekiʻe ka adsorption. Ma hope o ka calcined ʻana ma 900 ℃, ua hōʻike ka honua diatomaceous i ka siliceous circular sieve disc, a ua heheʻe kona mau kihi a puni. Ua ālai ʻia nā micropores i loko o ke kino kānana pōʻai ma muli o ka hoʻoheheʻe mālie ʻana, a ua wāwahi ʻia kekahi ʻāpana o ke kino kānana mua i mau ʻāpana.

Ma hope o ka calcination ma 1150 ℃, ua hoʻoheheʻe ʻia nā micropores ma ka ʻili o ka honua diatomaceous a nalowale, ua luku loa ʻia ke ʻano micropore o ke kino diatomaceous, a ua nalowale loa ka adsorption.

Hiki ke ʻike ʻia ʻo nā ʻano hana hana like ʻole o ka honua diatomaceous mai ka wahi hana like e hoʻololi nui i ka hopena adsorption o ka honua diatomaceous. No laila, Dr. Ni ka diatomaceous honua koho kiʻekiʻe-koʻo 'ana i ka lepo diatomaceous e like me ka mea nui maka mea o ka honua diatomaceous e hōʻoia i ka kū hoʻokahi aniani adsorption hale o ka honua diatomaceous aole i lukuia, a me ka adsorption hiki o ka lepo diatom ua hōʻoia 'ia i ka nui loa, e kau ana i ke kumu no ka functionality o Dr. Mud's diatom ea lepo e hoomaemae.
