Sechinhu chikuru chedhaka re diatom, ivhu re diatomaceous rinonyanya kushandisa chimiro chayo che microporous kuunza adsorption capacity ye macromolecular magasi akaita se benzene, formaldehyde, etc. Hunhu hwediatomaceous earth hunogadzirisa zvakananga kushanda kwedhaka re diatom Kuwedzera kune hutano hwe diatomite hunotaridzirwa nekugadzirwa kwe diatomite, yakakosha nzira ye diatomite ine adsorption yekugadzirwa kwayo. Parizvino, nzira dzinowanzo shandiswa dzekugadzirisa diatomite pamusika dzinonyanya kusanganisira kugocha uye kuverengera. Izvo zvinodikanwa zvekugocha zvakakwirira, kumhanya kunononoka, kubuda kwakaderera, uye mutengo wakakwira, nepo zvinodiwa zvekuverengera zvakaderera, kumhanya kunomhanya, uye mutengo wakaderera.

1. Kunonzi kugocha kunoreva kunyatso kudzora tembiricha inenge 500 madhigirii celsius, zvishoma nezvishoma kukwidza tembiricha yepasi diatomaceous, uye kugocha nekumhanya kusingaperi kweanopfuura maawa maviri, iyo inogona kuchengetedza yakawanda yepore kuvimbika uye yakanaka adsorption yepasi diatomaceous, uye inononoka Kuwedzera tembiricha uye kusinga gadzirise kupisa kunogona kubvisa organic tembiricha.zvachose, uye kuchena kwakakwirira uye zvimedu zvakafanana.

2. Calcining inoreva kuwedzera diatomaceous pasi kune co-solvent uye kuipisa muchoto pakupisa kwakanyanya kwe900 kusvika 1150 degrees kwemaminitsi gumi kusvika kumaminitsi makumi matatu. Iyo co-solvent inokurumidza kunyunguduka uye kusungira nediatomaceous pasi. Calcining inogona kuitwa nenguva shoma uye mutengo wakaderera. Zvisinei, nokuti tembiricha yakanyanyisa uye yakaoma kudzora, zviri nyore kupinza uye kupeta diatomite, iyo inoda kugadzika uye yakaputsika kusvika kune yakatsetseka inodiwa, zvichiita kukuvadza kwechipiri kune pores pamusoro pe diatomite. Sezvo iyo cosolvent inonyungudika uye inonamatira kumusoro kwepasi diatomaceous, ma pores epasi diatomaceous akavharika, uye iyo chaiyo nzvimbo yepasi diatomaceous yakaderedzwa. Uye zvakare, tembiricha yakakwira kusvika 1100 inonyungudika nyore uye inonyangarika ma micropores epasi diatomaceous, iyo micropore chimiro che diatomaceous muviri inoparadzwa zvachose, mamwe emadziro emadziro anonatswa uye akanyungudutswa, uye iyo yakawanda-vacancy chimiro chediatomaceous pasi inopindwa, zvichikonzera kuderedzwa kweadsorption.

Kuedza kwedhaka re diatom kwakaratidza kuti 100g yepasi diatomaceous yakaverengwa pa 500 madhigirii celsius kwemaawa maviri uye 5% co-solvent yakawedzerwa, uye ipapo nzvimbo yakaverengerwa pa 900 ° uye 1100 °, zvichiteerana, uye nzvimbo yakaonekwa pasi pekuongorora electron maikorosikopu.

Mushure mokunge calcination pa 500 °, nzvimbo yepasi diatomaceous yakakwana kwazvo, uye pores haina zviratidzo zvekuputsika kana fusion, zvichiratidza kuti ine yakakwirira adsorption. Mushure mekuverengerwa pa900 ℃, iyo diatomaceous pasi yakafumura siliceous denderedzwa sieve disc, uye mipendero yaro yakatenderedza yakanyungudika. Iwo ma micropores ari mudenderedzwa sieve muviri akavharika nekuda kwekunyungudika zvishoma nezvishoma, uye chikamu chemuviri wekutanga sieve chakatsemuka kuita zvidimbu.

Mushure mekuverenga pa1150 ℃, ma micropores ari pamusoro pevhu re diatomaceous akanyunguduka uye akanyangarika, chimiro che micropore chemuviri we diatomaceous chakaparadzwa zvachose, uye adsorption yakarasika zvachose.

Zvinogona kuoneka kuti kunyangwe nzira dzakasiyana dzekugadziridza dzepasi diatomaceous kubva munzvimbo imwechete yekugadzira zvinokonzeresa misiyano mikuru mukuita kweadsorption yepasi diatomaceous. Naizvozvo, Dr. Ni's diatomaceous earth inosarudza yakakwirira-yepamusoro yakagochwa diatomaceous pasi seyakanyanya mbishi yepasi diatomaceous kuti ive nechokwadi Iyo yakasarudzika crystal adsorption chimiro chediatomaceous earth haina kuparadzwa, uye iyo adsorption kugona kwedhaka redhiyamu inovimbiswa kusvika pamwero mukuru, kuisa hwaro hwekushanda kweDr.
