Dị ka isi ihe onwunwe nke diatom apịtị, diatomaceous ụwa tumadi na-eji ya microporous Ọdịdị na-eweta banyere adsorption ike nke macromolecular gas dị ka benzene, formaldehyde, wdg The àgwà nke diatomaceous ụwa kpọmkwem na-ekpebi ọrụ nke diatom apịtị Na mgbakwunye na àgwà nke diatomite kpebisiri ike site udidi nke diatomite a ọzọ mmetụta nke adsorption usoro nwere. Ka ọ dị ugbu a, usoro a na-ejikarị eme ihe maka nhazi diatomite n'ahịa bụ nke gụnyere ịsa nri na calcination. Ihe ndị a chọrọ n'ọkụ dị elu, ọsọ na-adị ngwa ngwa, mmepụta dị ala, na ọnụ ahịa dị elu, ebe ihe achọrọ calcination dị ala, ọsọ na-agba ọsọ, na ọnụ ahịa dị ala.

1. Ihe a na-akpọ iri nri na-ezo aka na ịchịkwa okpomọkụ nke ihe dị ka 500 degrees Celsius, jiri nwayọọ nwayọọ na-ebuli okpomọkụ nke ụwa diatomaceous, na-eri nri na-agba ọsọ ọsọ maka ihe karịrị awa 2, nke nwere ike ijide ọtụtụ n'ime iguzosi ike n'ezi ihe nke pore na ezigbo adsorption nke ụwa diatomaceous, na ọ na-adịghị ngwa ngwa The okpomọkụ ịrị elu na okpomọkụ okpomọkụ nwere ike wepụ organic impulities.kpamkpam, na ọcha dị elu na ahụ bụ edo.

2. Calcining na-ezo aka ịgbakwunye ụwa diatomaceous na co-solvent na kpo oku ya n'ime ọkụ na okpomọkụ dị elu nke 900 ruo 1150 degrees maka nkeji 10 ruo 30 nkeji. Ihe mgbaze na-agbaze ngwa ngwa ma jikọta ya na ụwa diatomaceous. Enwere ike ịme calcining na obere oge na ọnụ ala dị ala. Otú ọ dị, n'ihi na okpomọkụ dị oke elu ma sie ike ịchịkwa, ọ dị mfe sinter na pellet diatomite, nke dị mkpa ka a na-agbanye ala ma gbajie ya na mma dị mma achọrọ, na-akpata mmebi nke abụọ na pores n'elu diatomite. Ka ihe mkpuchi ahụ na-agbaze ma na-arapara n'elu ụwa diatomaceous, a na-egbochi pores nke ụwa diatomaceous, na ebe a kapịrị ọnụ nke ụwa diatomaceous na-ebelata. Ke adianade do, elu okpomọkụ dị elu dị ka 1100 mfe agbaze na-apụ n'anya na micropores nke diatomaceous ụwa, micropore Ọdịdị nke diatomaceous ahu na-kpamkpam bibiri, ụfọdụ n'ime pore mgbidi na-crystalized na gbazee, na multi-ohere Ọdịdị nke diatomaceous ụwa na-penetrated, n'ihi na mbelata adsorption.

Nnwale nke apịtị diatom gosiri na 100g nke ụwa diatomaceous ka a na-agbakọ na 500 degrees Celsius maka awa 2 na 5% ihe mgbaze na-agbakwunyere, wee mee ka elu ahụ dị na 900 ° na 1100 °, n'otu n'otu, a na-ahụkwa elu n'okpuru nyocha nke eletrọn microscope.

Mgbe calcination na 500 °, elu nke diatomaceous ụwa zuru oke, na pores enweghị ihe ịrịba ama nke ọdịda ma ọ bụ ngwakọta, na-egosi na ọ nwere nnukwu adsorption. Mgbe agbachara ya na 900 ℃, ụwa diatomaceous ekpughere diski okirikiri siliceous okirikiri, na akụkụ ya gbara ya gburugburu agbazewo. A gbochiri micropores dị n'ime ahụ sieve okirikiri n'ihi na-agbaze nke nta nke nta, na akụkụ nke ahụ sieve mbụ gbajiri n'iberibe.

Mgbe calcination na 1150 ℃, micropores dị n'elu ụwa diatomaceous gbazere ma pụọ ​​n'anya, e bibiri usoro micropore nke ahụ diatomaceous kpamkpam, adsorption ahụ furu efu kpamkpam.

Enwere ike ịhụ na ọbụna usoro nhazi dị iche iche nke ụwa diatomaceous site n'otu mpaghara mmepụta ga-eme ka nnukwu ọdịiche dị na mmetụta mgbasa ozi nke ụwa diatomaceous. Ya mere, Dr. Ni's diatomaceous ụwa na-ahọrọ elu-edu ṅara n'ọkụ diatomaceous ụwa dị ka isi akụrụngwa nke diatomaceous ụwa iji hụ na The pụrụ iche crystal adsorption Ọdịdị nke diatomaceous ụwa na-adịghị ebibi, na adsorption ikike nke diatom apịtị na-ekwe nkwa na nke kasị ukwuu n'ókè, ịtọ ntọala maka ọrụ nke Dr. Mud si dị ọcha ikuku diatom.
