Diatomite ndi mwala wachilengedwe wa siliceous sedimentary, womwe umapangidwa makamaka ndi zotsalira za ma diatoms akale. Mankhwala ake makamaka ndi SiO2, wokhala ndi Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5 ndi zinthu zachilengedwe. Ma mineral a diatomite makamaka ndi opal ndi mitundu yake, kutsatiridwa ndi mchere wa dongo - hydromica, kaolinite ndi zinyalala za mchere. Zinyalala za mchere zimaphatikizapo Shi Ying, feldspar, biotite ndi zinthu zachilengedwe. Zomwe zili mu zinthu zachilengedwe zimakhala kuyambira pazidutswa mpaka kupitirira 30%. Diatomite ndi yoyera, yoyera ngati imvi, imvi komanso yofiirira ngati imvi, ndipo ili ndi zinthu zabwino, zomasuka, zopepuka, zoboola, zoyamwa komanso zolowa m'madzi.
Zinthu zowonjezera zokutira za Diatomite, zokhala ndi ma porosity ambiri, kuyamwa kwamphamvu, kukhazikika kwa mankhwala, kukana kukwawa, kutentha
Kukana ndi makhalidwe ena, kungapereke mawonekedwe abwino kwambiri a pamwamba pa zokutira, kugwirizana, kukhuthala ndi kumamatira. Chifukwa cha kuchuluka kwa ma pore ake, kumatha kufupikitsa nthawi youma. Kungachepetsenso kuchuluka kwa utomoni, kuchepetsa ndalama.

Ntchito yaikulu
Nthawi zonse imagwiritsidwa ntchito mu utoto wa latex, utoto wamkati ndi wakunja wa khoma, utoto wa alkyd resin, utoto wa polyester ndi machitidwe ena okutira,
makamaka popanga zokutira zomangamanga.
Pogwiritsa ntchito zokutira ndi utoto, kuwala kwa pamwamba pa filimu yophimba kumatha kulamulidwa mofanana, kukana kukanda ndi kukana kukanda kwa filimu yophimba kumatha kuwonjezeka, chinyezi ndi kuchotsa fungo loipa zimatha kuchotsedwa, mpweya ukhoza kuyeretsedwa, ndipo makhalidwe a kutchinjiriza mawu, kusalowa madzi, kutchinjiriza kutentha ndi malo abwino olowera amatha kukwaniritsidwa.

Matope a Diatom amapangidwa makamaka ndi zinthu zachilengedwe zopanda chilengedwe, ndi zinthu zobiriwira zoteteza chilengedwe, zokha zopanda kuipitsa chilengedwe, zopanda fungo. Matope a Dialgae ali ndi chitetezo chachilengedwe cha chilengedwe, ukadaulo wamanja, malamulo a chinyezi, mpweya.
kuyeretsa, choletsa moto, kuyamwa kwa phokoso ndi kuchepetsa phokoso, kusunga kutentha ndi kutchinjiriza, kuteteza maso, makoma
Kudziyeretsa, kukhala ndi moyo wautali komanso makhalidwe ndi ntchito zina, ndi utoto wa latex ndi mapepala ophimba mapepala ndi zokongoletsera zina zachikhalidwe
zipangizo sizingayerekezedwe.
Zinthu zowonjezera za Diatomite zili ndi ma porosity akuluakulu, kuyamwa kwamphamvu, mphamvu zokhazikika za mankhwala, kukana kuvala komanso kukana kutentha.
