Zothandizira zosefera za Diatomaceous lapansi zimakhala ndi mawonekedwe abwino a microporous, magwiridwe antchito adsorption, komanso kukana kolimba, zomwe sizimangopangitsa madzi osefedwa kuti akwaniritse chiwongolero chabwino, komanso kusefa zolimba zoyimitsidwa bwino, kuwonetsetsa kuti zimveka bwino.Dziko la Diatomaceous ndi dothi lakale la diatom lomwe lili ndi cell imodzi.Makhalidwe ake ndi monga opepuka, porous, apamwamba-mphamvu, osavala, kusungunula, kutchinjiriza, adsorption, ndi kudzaza, mwa zina zabwino kwambiri.

Dziko la Diatomaceous ndi dothi lakale la diatom lomwe lili ndi cell imodzi.Makhalidwe ake ndi monga opepuka, porous, apamwamba-mphamvu, osavala, kusungunula, kutchinjiriza, adsorption, ndi kudzaza, mwa zina zabwino kwambiri.Ali ndi kukhazikika kwamankhwala.Ndizinthu zofunikira zamafakitale zotchinjiriza, kugaya, kusefera, kutsatsa, anticoagulation, kugwetsa, kudzaza, ndi chonyamulira.Itha kugwiritsidwa ntchito kwambiri m'mafakitale monga zitsulo, uinjiniya wamankhwala, magetsi, ulimi, feteleza, zomangira ndi zinthu zotchinjiriza.Itha kugwiritsidwanso ntchito ngati zodzaza mafakitale zamapulasitiki, mphira, zoumba, kupanga mapepala, ndi mafakitale ena.

Zothandizira zosefera za Diatomaceous lapansi zimagawidwa kukhala zinthu zowuma, zopangidwa ndi calcined, ndi zinthu zopangidwa ndi flux calcined malinga ndi njira zosiyanasiyana zopangira.
① Zinthu zouma
Dothi loyeretsedwa, lowumitsidwa, ndi lophwanyidwa silika zouma zouma zimawumitsidwa pa kutentha kwa 600-800 ° C ndikuphwanyidwa.Mankhwalawa ali ndi kukula kwa tinthu tating'ono ndipo ndi oyenera kusefera mwatsatanetsatane.Nthawi zambiri amagwiritsidwa ntchito limodzi ndi zida zina zosefera.Zouma zouma nthawi zambiri zimakhala zachikasu, komanso zimakhala zoyera zamkaka komanso zotuwa.

② Mankhwala owerengeka
Zida zoyeretsedwa, zouma, ndi zophwanyika za diatomaceous lapansi zimadyetsedwa mu ng'anjo yozungulira, yotenthedwa pa kutentha kwa 800-1200 ° C, kenako ndikuphwanyidwa ndikusiyidwa kuti mupeze mankhwala opangidwa ndi calcined.Poyerekeza ndi mankhwala youma, permeability mankhwala calcined ndi kuposa katatu apamwamba.Zopangira calcined nthawi zambiri zimakhala zofiira mopepuka.

③ Flux calcined mankhwala
Pambuyo pa kuyeretsedwa, kuyanika, ndi kuphwanya, zida zapadziko lapansi za diatomaceous zimawonjezeredwa ndi zinthu zazing'ono zomwe zimasinthasintha monga sodium carbonate ndi sodium kolorayidi, ndi calcined pa kutentha kwa 900-1200 ° C. Pambuyo kuphwanya ndi kukula kwa tinthu, flux calcined mankhwala anapezedwa.The permeability wa mankhwala flux calcined chawonjezeka kwambiri, amene ndi oposa 20 kuposa zinthu youma.Zopangidwa ndi calcined za flux nthawi zambiri zimakhala zoyera, ndipo Fe2O3 ikakhala yochuluka kapena mlingo wa flux ndi wotsika, umawoneka ngati pinki.

Zoyipa zazikulu za diatomaceous earth filter aids ndi:

1. Kusowa kwazinthu.Kupanga zida zosefera za diatomaceous earth zimafunikira nthaka yapamwamba kwambiri ya diatomaceous yokhala ndi ma diatom apamwamba.Ngakhale kuti dziko la China lili ndi zinthu zambiri zapadziko lapansi zotchedwa diatomaceous, unyinji wake ndi migodi yapakatikati mpaka yotsika, yomwe ndi yovuta kukwaniritsa zofunikira zopanga;

2. Mtengo wopangira ndi wokwera kwambiri.Njira yopangira dziko lapansi ya diatomaceous ndi yovuta kwambiri, komanso yophatikizidwa ndi mtengo wapamwamba wa zipangizo zapadziko lapansi za diatomaceous, mtengo wopangira zida za diatomaceous earth filter ku China zasungidwa pamlingo wapamwamba;

3. Kusefedwa kumachepa pang'onopang'ono ndipo kachulukidwe kake ndi kokwera.Kuonjezera zambiri malinga ndi khalidwe lake nthawi zambiri sikukwaniritsa zofunikira, ndipo kuwonjezerapo kumawonjezera mtengo.Anthu ena akufuna kupanga mankhwala amtundu wa diatomaceous lapansi omwe ali ndi kachulukidwe kakang'ono kocheperako, koma chifukwa cha zofooka pakupanga ndi kapangidwe kazinthu zopangira, zotsatira zogwira mtima sizinapezeke mpaka pano;

4. Kukhazikika kwamankhwala sikoyenera.Zomwe zili muzinthu zovulaza monga chitsulo ndi calcium mu dziko la diatomaceous ndizokwera kwambiri ndipo zimakhalapo m'malo olekanitsidwa, kotero kuti kuwonongeka kwake kumakhala kwakukulu.Mukasefa zakumwa zambiri ndi zakumwa zoledzeretsa, kusungunuka kwachitsulo chambiri kumatha kusokoneza kukoma ndi kukoma kwa mankhwalawa.
