Njengento eyinhloko yodaka lwe-diatom, umhlaba we-diatomaceous ikakhulukazi usebenzisa isakhiwo sawo se-microporous ukuze ulethe amandla okukhangisa amagesi ama-macromolecular njenge-benzene, i-formaldehyde, njll. Izinga lomhlaba we-diatomaceous linquma ngokuqondile ukusebenza kodaka lwe-diatom Ngaphezu kwekhwalithi ye-diatomite enqunywa ukubunjwa kwe-diatomite, indlela ebaluleke kakhulu yokucubungula i-diatomite inethonya elikhulu ekucutshungulweni kwayo. Njengamanje, izindlela ezisetshenziswa kakhulu zokucubungula i-diatomite emakethe ikakhulukazi zifaka ukugazinga nokubala. Izidingo zokuthosa ziphezulu, isivinini sihamba kancane, okukhiphayo kuphansi, futhi izindleko ziphezulu, kuyilapho izidingo zokubala ziphansi, isivinini siyashesha, futhi izindleko ziphansi ngokwemvelo.

1. Lokhu okubizwa ngokuthi ukugazinga kubhekisela ekulawuleni ngokuqinile izinga lokushisa elingu-500 degrees Celsius, ukuphakamisa kancane kancane izinga lokushisa lomhlaba we-diatomaceous, nokuwosa ngesivinini esingaguquki isikhathi esingaphezu kwamahora angu-2, okungagcina iningi lobuqotho bembotshana kanye nokukhanyiswa okuhle komhlaba we-diatomaceous, futhi kuhamba kancane.ngokuphelele, futhi ubumhlophe buphakeme futhi izinhlayiya zifana.

2. Ukubala kubhekisela ekwengezeni umhlaba we-diatomaceous ku-co-solvent nokuwufudumeza esithandweni ekushiseni okuphezulu kuka-900 kuya ku-1150 degrees imizuzu eyi-10 kuya kumaminithi angu-30. I-co-solvent iyancibilika ngokushesha futhi ihlangane nomhlaba we-diatomaceous. Calcining kungenziwa ngesikhathi esincane kanye nezindleko eziphansi. Kodwa-ke, ngenxa yokuthi izinga lokushisa liphezulu kakhulu futhi kunzima ukulilawula, kulula ukucwilisa kanye ne-pellet i-diatomite, edinga ukugaywa futhi iphulwe ekuqineni okudingekayo, okwenza umonakalo wesibili kuma-pores ebusweni be-diatomite. Njengoba i-cosolvent incibilika futhi inamathela ebusweni bomhlaba we-diatomaceous, ama-pores omhlaba we-diatomaceous ayavinjelwa, futhi indawo ethile yomhlaba we-diatomaceous iyancishiswa. Ngaphezu kwalokho, izinga lokushisa eliphakeme elifinyelela ku-1100 liyancibilika kalula futhi linyamalale ama-micropores omhlaba we-diatomaceous, isakhiwo se-micropore somzimba we-diatomaceous sibhujiswa ngokuphelele, ezinye izindonga ze-pore zicwebezela futhi ziyancibilika, futhi isakhiwo sezikhala eziningi zomhlaba we-diatomaceous singena, okuholela ekunciphiseni ukukhanga.

Ukuhlolwa kodaka lwe-diatom kubonise ukuthi i-100g yomhlaba we-diatomaceous yabalwa ku-500 degrees Celsius amahora angu-2 futhi i-co-solvent engu-5% yengezwa, kwase kuthi indawo engaphezulu yabalwa ku-900 ° no-1100 °, ngokulandelana, futhi ingaphezulu labonwa ngaphansi kwe-electron microscope yokuskena.

Ngemuva kokubala ku-500 °, ubuso bomhlaba we-diatomaceous buphelele kakhulu, futhi ama-pores awanazo izimpawu zokuwa noma ukuhlanganiswa, okubonisa ukuthi kune-adsorption ephezulu. Ngemva kokubalwa ku-900 ℃, umhlaba we-diatomaceous wadalula i-siliceous circular sieve disc, futhi imiphetho yayo ezungezile yayincibilikile. Ama-micropores emzimbeni wesisefo esiyindilinga ayevimbekile ngenxa yokuncibilika kancane kancane, futhi ingxenye yomzimba wokuqala wesisefo yaphulwa yaba yizicucu.

Ngemuva kokubala ku-1150 ℃, ama-micropores ebusweni bomhlaba we-diatomaceous ancibilika futhi wanyamalala, isakhiwo se-micropore somzimba we-diatomaceous sacekelwa phansi ngokuphelele, futhi i-adsorption yalahleka ngokuphelele.

Kungabonakala ukuthi ngisho namasu ahlukene okucubungula omhlaba we-diatomaceous avela endaweni efanayo ekhiqizayo azodala umehluko omkhulu emthelela wokukhanga we-diatomaceous earth. Ngakho-ke, umhlaba we-diatomaceous kaDkt. Ni ukhetha izinga eliphezulu lomhlaba ogazingiwe we-diatomaceous njengento eyinhloko yokusetshenziswa komhlaba we-diatomaceous ukuze kuqinisekiswe Isakhiwo esiyingqayizivele se-crystal adsorption yomhlaba we-diatomaceous asibhujiswa, futhi amandla okukhanga odaka lwe-diatom aqinisekisiwe ngezinga elikhulu kakhulu, abeka isisekelo sokusebenza kwe-diatom air mud's purify diatom's air mud's purify Dr.
