Diatomaceous lapansi kwenikweni amapangidwa ndi kudzikundikira zigawo za zotsalira zakale diatom zomera ndizamoyo zina za cell imodzi. Nthawi zambiri, dziko lapansi la diatomaceous limakhala loyera, monga loyera, imvi, imvi, ndi zina zotero, chifukwa kachulukidwe ake nthawi zambiri amakhala 1.9 mpaka 2.3 pa kiyubiki mita, kotero mawonekedwe ake amkati amakhala ndi voids yayikulu, ndipo porosity yake imafika 100% ikauma Makumi makumi asanu ndi anayi kapena kuposerapo, kotero kuti dziko lapansi la diatomaceous ndi losavuta kugaya kukhala ufa. Chifukwa chake, nthaka ya diatomaceous yomwe idagulidwa pamsika nthawi zambiri imakhala yaufa.

Popeza chinthu chachikulu chopangidwa ndi dziko lapansi la diatomaceous ndi diatom, limapezeka makamaka ku Shandong, Jiangxi, Yunnan, Sichuan ndi malo ena okhala ndi madzi okwanira. Kuphatikiza apo, kuphatikiza kusiyanasiyana kwa njira zopangira ma diatomite, pali mitundu yambiri yazogulitsa za diatomite. Masiku ano, msika umagawidwa m'mitundu itatu: montmorillonite, dongo loyera, ndi attapulgite.

Ponena za decolorization ya diatomite, pickling ndi Kuwotcha nthawi zambiri amagwiritsidwa ntchito, ndipo m'makampani amasiku ano, kuti apititse patsogolo zotsatira za mankhwalawa, carbon activated idzawonjezedwa kuonetsetsa kuti zinthu zakuda mu yankho ndi zotsatira zina zoipa pa khalidwe la mankhwala. Chinthucho chinamwetsedwa.

Chiyerekezo cha kuchuluka kwa dziko lapansi la diatomaceous kupita ku kaboni woyatsidwa zitha kutanthauza 0.2% mpaka 0.3% ya nkhaniyo. Ndipo nthawi zonse, kusakaniza kwa mphindi khumi kumatha kuthetsa zinthu zomwe zimakhala ndi zotsatira zoipa pa mankhwala. Anthu ambiri amagwiritsa ntchito njira yosavuta ya utomoni pamene decolorizing sanali woyera diatomaceous lapansi, koma kwenikweni, njira imeneyi si ntchito, sachedwa mavuto, ndipo sakwaniritsa kuyembekezera zotsatira, choncho tikulimbikitsidwa kuti musaope mavuto , Ikadali ikuchitika ndi pickling ndi Kuwotcha, ndipo palinso zipangizo pa msika kugula, ndipo mtengo ndi chilungamo.
