Diatomaceous earth filter aid li na le sebopeho se setle sa microporous, adsorption performance, le compressive resistance, tse sa nolofalletseng feela hore mokelikeli o hloekisitsoeng o fihlele tekanyo e ntle ea phallo, empa hape o sefa lintho tse tiileng tse emisitsoeng, ho netefatsa ho hlaka.Diatomaceous Earth ke sediment ea mesaletsa ea khale e nang le sele e le 'ngoe ea diatom.Litšobotsi tsa eona li kenyelletsa boima bo bobebe, li-porous, matla a phahameng, ho se mamelle, ho suthela, ho kenya letsoho, ho bapatsa le ho tlatsa, har'a lisebelisoa tse ling tse ntle haholo.

Diatomaceous Earth ke sediment ea mesaletsa ea khale e nang le sele e le 'ngoe ea diatom.Litšobotsi tsa eona li kenyelletsa boima bo bobebe, li-porous, matla a phahameng, ho se mamelle, ho suthela, ho kenya letsoho, ho bapatsa le ho tlatsa, har'a lisebelisoa tse ling tse ntle haholo.E na le botsitso bo botle ba lik'hemik'hale.Ke thepa ea bohlokoa ea indasteri bakeng sa ho kenya letsoho, ho sila, ho sefa, ho bapatsa, anticoagulation, demolding, ho tlatsa le ho tsamaisa.E ka sebelisoa haholo liindastering tse kang metallurgy, boenjiniere ba lik'hemik'hale, motlakase, temo, manyolo, thepa ea mohaho le lihlahisoa tsa ho pata.E ka sebelisoa hape e le li-filler tse sebetsang tsa indasteri bakeng sa polasetiki, rabara, ceramics, ho etsa pampiri le liindasteri tse ling.

Lisebelisoa tsa "diatomaceous earth filter" li arotsoe ka lihlahisoa tse omeletseng, lihlahisoa tse nang le calcined, le lihlahisoa tsa flux calcined ho latela mekhoa e fapaneng ea tlhahiso.
① Lihlahisoa tse omisitsoeng
Sehlahisoa se hloekisitsoeng, se omisitsoeng pele, le se pshatlehileng sa silika se omisitsoeng se omisitsoe ka mocheso oa 600-800 ° C ebe sea pshatleha.Sehlahisoa sena se na le boholo bo botle haholo ba likaroloana 'me se loketse ho sefa ka mokhoa o nepahetseng.Hangata e sebelisoa hammoho le lisebelisoa tse ling tsa ho hloekisa.Sehlahisoa se omisitsoeng hangata se mosehla o bobebe, empa hape se na le bosoeu ba lebese le bohlooho bo bobebe.

② Sehlahisoa se nang le calcined
Thepa e hloekisitsoeng, e omisitsoeng, le e pshatlehileng ea diatomaceous ea lefats'e e kenngoa ka sebōping sa rotary, se calcined ka mocheso oa 800-1200 ° C, ebe sea siloa ebe se kenngoa ho fumana sehlahisoa sa calcined.Ha ho bapisoa le lihlahisoa tse omeletseng, ho kenella ha lihlahisoa tsa calcined ho feta makhetlo a mararo.Lihlahisoa tse nang le calcined hangata li khubelu ka 'mala.

③ Lihlahisoa tsa Flux calcined
Ka mor'a ho hloekisoa, ho omisoa le ho senya, lihlahisoa tse tala tsa lefats'e la diatomaceous li eketsoa ka lintho tse fokolang tse kang sodium carbonate le sodium chloride, 'me li calcined ka mocheso oa 900-1200 ° C. Ka mor'a ho senya le ho hlophisa boholo ba likaroloana, flux calcined sehlahisoa se fumanoa.The permeability ea lihlahisoa tsa flux calcined e eketsehile haholo, e leng makhetlo a fetang 20 a lihlahisoa tse omeletseng.Lihlahisoa tse calcined tsa flux hangata li tšoeu, 'me ha litaba tsa Fe2O3 li le holimo kapa tekanyo ea flux e le tlase, e bonahala e le pinki e bobebe.

Litšitiso tse kholo tsa li-diatomaceous earth filter aid ke:

1. Khaello ea lisebelisoa.Tlhahiso ea lithuso tsa "diatomaceous earth filter" e hloka lefats'e la diatomaceous la boleng bo holimo le nang le diatom tse phahameng.Le hoja Chaena e na le mehloli e mengata ea lefats'e ea diatomaceous, bongata bo boholo ke merafo ea lefatše ea diatomaceous e bohareng ho ea tlaase, e leng thata ho finyella litlhoko tsa tlhahiso;

2. Theko ea tlhahiso e batla e phahame.Ts'ebetso ea tlhahiso ea lefats'e ea diatomaceous e batla e rarahane, 'me e kopantsoe le theko e phahameng ea boleng bo phahameng ba lisebelisoa tsa lefats'e tsa diatomaceous, litšenyehelo tsa tlhahiso ea lithuso tsa lihlahisoa tsa lefats'e tsa diatomaceous Chaena li bolokiloe ka mokhoa o phahameng;

3. Sekhahla sa ho sefa se batla se lieha 'me bongata ba bongata bo phahame.Ho eketsa ho feta ho latela boleng ba eona hangata ha ho finyelle litlhoko tse lebelletsoeng, 'me ho eketsa ho feta ho tla eketsa litšenyehelo.Batho ba bang ba batla ho hlahisa lihlahisoa tsa mofuta oa lefats'e oa diatomaceous ka bongata bo fokolang ba bongata, empa ka lebaka la mefokolo ea sebopeho le sebopeho sa lisebelisoa tse tala, liphello tse khotsofatsang ha li e-s'o finyelloe ho fihlela joale;

4. Ho tsitsa ha lik'hemik'hale ha hoa nepahala.Likahare tsa likarolo tse kotsi tse kang tšepe le k'halsiamo lefatšeng la diatomaceous li batla li phahame 'me li teng sebakeng se arohaneng, kahoo sekhahla sa ho qhibiliha ha sona se phahame.Ha u sefa lino tse ngata le lino tse tahang, ho qhibiliha ha tšepe e ngata ho ka ama tatso le tatso ea sehlahisoa.
