Sida wax ugu muhiimsan ee dhoobada diatomaceous, dhulka diatomaceous inta badan isticmaalaa qaab-dhismeedka microporous si ay u keenaan oo ku saabsan awoodda adsorption ee gaasaska macromolecular sida benzene, formaldehyde, iwm Tayada dhulka diatomaceous si toos ah u go'aamisa functionality ee dhoobada diatom Intaa waxaa dheer in tayada diatomite go'aamiyay texture of diatomite saamayn aad u badan oo ku saabsan habka diatomite saamayntiisa. Waqtigan xaadirka ah, hababka sida caadiga ah loo isticmaalo ka-hortagga diatomite ee suuqa inta badan waxaa ka mid ah duban iyo calcination. Shuruudaha dubantu waa sarreeyaa, xawaaruhu waa gaabis, wax soo saarku waa yar yahay, kharashkuna waa sarreeyaa, halka shuruudaha calcination ay yar yihiin, xawaaruhu waa dhakhso, kharashkuna si dabiici ah ayuu u hooseeyaa.

1. Waxa loogu yeero duban waxa loola jeedaa in si adag loo xakameeyo heerkulka ilaa 500 darajo Celsius, si tartiib tartiib ah kor loogu qaado heerkulka dhulka diatomaceous, iyo duban xawaare joogto ah in ka badan 2 saacadood, taas oo ilaalin karta inta badan daacadnimada daloolka iyo adsorption wanaagsan ee dhulka diatomaceous, waana gaabis Kor u kaca heerkulka iyo kulaylka joogtada ah ayaa ka saari kara cilladaha dabiiciga ah.gebi ahaan, iyo caddaanku waa sarreeyaa, qaybuhuna waa lebis.

2. Calcining waxaa loola jeedaa in lagu daro dhulka diatomaceous isku-darka iyo kuleylinta foornada heerkulka sare ee 900 ilaa 1150 darajo 10 daqiiqo ilaa 30 daqiiqo. Isku-darka-isku-darka si dhakhso ah ayuu u dhalaali karaa oo u xidhaa dhulka diatomaceous. Calcining waxaa lagu samayn karaa waqti yar iyo kharash yar. Si kastaba ha ahaatee, sababtoo ah heerkulku aad ayuu u sarreeyaa oo ay adag tahay in la xakameeyo, way sahlan tahay in la gooyo oo la jeexjeexo diatomite, taas oo u baahan in la dhigo oo la jebiyo ganaaxa loo baahan yahay, taasoo keenta dhaawac labaad oo soo gaara daldaloolada dusha sare ee diatomite. Marka uu qaboojiyaha dhalaalayo oo uu ku dheggan yahay dusha sare ee dhulka diatomaceous, daloollada dhulka diatomaceous waa la xirayaa, oogada gaarka ah ee dhulka diatomaceous waa la dhimay. Intaa waxaa dheer, heerkulka sare ee sare sida 1100 si fudud u dhalaali iyo baaba'aan micropores of dhulka diatomaceous, qaab-dhismeedka micropore ee diatomaceous jirka gebi ahaanba waa la baabi'iyay, qaar ka mid ah darbiyada daldaloola waa crystallized oo dhalaalay, iyo qaab-dhismeedka bannaan ee badan ee dhulka diatomaceous waa la dhex galiyay, taasoo keentay hoos u adsorption.

Tijaabada dhoobada diatom ayaa muujisay in 100g oo dhulka diatomaceous ah lagu dajiyay 500 darajo Celsius muddo 2 saacadood ah waxaana lagu daray 5% isku dar ah, ka dibna dusha sare ayaa lagu qiyaasaa 900 ° iyo 1100 °, siday u kala horreeyaan, dusha sare waxaa lagu arkay mikroskoob elektaroonik ah.

Ka dib calcination at 500 °, oogada dhulka diatomaceous waa mid aad u dhameystiran, iyo daldaloolada ma laha calaamado burbur ama fusion, taasoo muujinaysa in ay leedahay adsorption sare. Ka dib markii la kariyey at 900 ℃, dhulkii diatomaceous wuxuu soo bandhigay saxanka shaandhada siliceous, iyo cidhifyada ku hareeraysan ayaa dhalaalay. Micropores-ka ku jira shaandhada wareegta ah waa la xiray sababtoo ah dhalaalid tartiib tartiib ah, iyo qayb ka mid ah shaandhada asalka ah ayaa la jajabiyey.

Ka dib markii calcination at 1150 ℃, micropores on dusha dhulka diatomaceous dhalaalay oo la waayay, qaab-dhismeedka micropore ee jidhka diatomaceous gebi ahaanba burburay, iyo adsorption gebi ahaanba lumay.

Waxaa la arki karaa in xitaa farsamooyinka farsamaynta kala duwan ee dhulka diatomaceous ee isla goobta wax soo saarka ay keeni doonto kala duwanaansho weyn oo saameyn ku yeelashada dhulka diatomaceous. Sidaa darteed, Dr. Ni ee dhulka diatomaceous wuxuu doortaa tayada sare ee la dubay dhulka diatomaceous sida alaabta ceeriin ee ugu weyn ee dhulka diatomaceous si loo hubiyo in qaab dhismeedka adsorption crystal gaar ah ee dhulka diatomaceous aan la baabbi'in, iyo awoodda adsorption ee dhoobada diatomaceous waa dammaanad ilaa xadka ugu weyn, dhigayay aasaaska u shaqaynta ee Dr. Mud ee nadiifinta dhoobada hawada.
