Ma diatoms mudziko lapansi diatomaceousali ndi mawonekedwe osiyanasiyana, monga ma disc, singano, masilindala, nthenga ndi zina zotero. Kuchulukana kwakukulu ndi 0.3 ~ 0.5g / cm3, kuuma kwa Mohs ndi 1 ~ 1.5 (diatom bone particles ndi 4.5 ~ 5mm), porosity ndi 80 ~ 90%, ndipo imatha kuyamwa madzi 1.5 - 4 nthawi ya kulemera kwake. Ndi kutentha , Woyendetsa bwino wa magetsi ndi phokoso, malo osungunuka 1650 ~ 1750 ° C, kukhazikika kwa mankhwala, osasungunuka mu asidi aliwonse amphamvu kupatula hydrofluoric acid, koma amasungunuka muzitsulo za alkali.

Ambiri mwa silika wa dziko lapansi diatomaceous ndi amorphous, ndipo zomwe zili mu sungunuka wa silicic acid mu alkali ndi 50-80%. Amorphous SiO2 imakhala yonyezimira ikatenthedwa mpaka 800-1000 ° C, ndipo asidi osungunuka a silicic mu alkali amatha kuchepetsedwa mpaka 20-30%. 1.5 Mineral properties Diatomite ndi mtundu wa mwala wokhala ndi chilengedwe. Amapangidwa makamaka ndi 80-90%, ndipo ena mpaka 90% ya diatom frustules. Wogula wamkulu wa silicon oxide m'madzi a m'nyanja ndi m'madzi am'nyanja ndi ma diatoms, omwe amapanga diatom sludge. Panthawi ya diagenesis, diatomite imapangidwa kudzera mu gawo la petrochemical. Zipolopolo za diatom zimapangidwa ndi opal. Pa kukula ndi kubereka kwa diatoms, imatenga silika ya colloidal m'madzi ndipo pang'onopang'ono imasandulika kukhala opal.

Zambiri za diatom mudziko lapansi diatomaceous, zonyansa zocheperako, mtundu wake umakhala woyera komanso wopepuka. Mphamvu yokoka yeniyeni nthawi zambiri imakhala 0.4-0.9. Chifukwa diatomite ili ndi mabowo ambiri a zipolopolo, diatomite imakhala ndi porous. Kuchuluka kwa diatomite ndi 90-92%. Imayamwa madzi mwamphamvu komanso lilime lomata. Chifukwa cha tinthu tating'onoting'ono ta diatom, pangani dziko la diatomaceous kukhala labwino komanso losalala. Dziko la Diatomaceous silisungunuka mu asidi (HCl, H2S04, HN03), koma limasungunuka mu HF ndi K0H.

Diatomndi mtundu wa ndere za selo imodzi zomwe zinayamba kuonekera padziko lapansi. Amakhala m'madzi a m'nyanja kapena m'madzi a m'nyanja, ndipo mawonekedwe ake ndi ochepa kwambiri, nthawi zambiri amakhala ndi ma microns angapo mpaka khumi ndi awiri. Diatom imatha kupanga photosynthesis ndi zinthu zodzipangira zokha. Nthawi zambiri zimakula ndi kuberekana pamlingo wowopsa. Zotsalira zake zidasungidwa kuti zipange dziko lapansi la diatomaceous. Ndi diatomu iyi yomwe imapereka mpweya kudziko lapansi kudzera mu photosynthesis ndikulimbikitsa kubadwa kwa anthu, nyama ndi zomera. Chigawo chachikulu cha dziko la diatomaceous ndi silicic acid. Pali ma pores ambiri pamtunda, omwe amatha kuyamwa ndikuwola fungo lachilendo mumlengalenga, ndipo ali ndi ntchito zowongolera chinyezi ndi kununkhira. Zipangizo zomangira zomwe zimapangidwa pogwiritsa ntchito nthaka ya diatomaceous monga zopangira sizingokhala ndi mawonekedwe osayaka, kutulutsa chinyezi, kununkhira komanso kutsekemera bwino, komanso zimatha kuyeretsa mpweya, kutsekereza mawu, kutsekereza madzi komanso kutentha.

Jilin Yuantong Mining Co., Ltd. ndi kampani yaukadaulo yophatikiza migodi ya diatomite, kafukufuku ndi chitukuko, kukonza, ndikupanga zinthu zingapo za diatomite. Ndilo gawo labwino kwambiri komanso nkhokwe zazikulu kwambiri zama minerals ofanana m'dziko langa, komanso ndi chiyembekezo chakukula kwapadziko lonse lapansi komwe Diatomite ikuyembekezeka. Kampani yathu imapanga zida za diatomite monga zida zosefera za diatomite, zodzaza ma diatomite, ndi zida za diatomite. Zogulitsazo ndizodalirika komanso zomveka pamtengo, ndipo zimalandiridwa bwino ndi makasitomala.
