Nyika yeDiatomaceous imhando yedombo resiliceous rinopararira munyika dzakadai seChina, United States, Japan, Denmark, France, Romania, nezvimwewo. Idombo resiliceous sedimentary rine biogenic, rinonyanya kuumbwa nemasara ediatoms ekare. Makemikari aro anonyanya kuumbwa neSiO2, iyo inogona kumirirwa neSiO2 · nH2O, uye mineral structure yayo ndeye opal uye mhando dzayo. Matura evhu rediatomaceous muChina anosvika mamiriyoni mazana matatu nemakumi maviri ematani, ane mukana wekuchengetedza anopfuura mabhiriyoni maviri ematani, akanyanya kuunganidzwa muEast China neNortheast China. Pakati pavo, Jilin (54.8%, neLinjiang City muJilin Province iri iyo yekutanga kuchengetwa kwakaratidzwa muAsia), Zhejiang, Yunnan, Shandong, Sichuan, nedzimwe nzvimbo dzine kupararira kwakakura, asi ivhu remhando yepamusoro rinongowanikwa munzvimbo yeChangbai Mountain yeJilin, uye mamwe mamineral akawanda ivhu regiredhi rechitatu kusvika rechina. Nekuda kwehuwandu hwakawanda hwekusvibiswa, harigone kugadziriswa uye kushandiswa zvakananga. Chikamu chikuru chevhu rediatomaceous semutakuri iSiO2. Semuenzaniso, chikamu chinoshanda che industrial vanadium catalyst iV2O5, co catalyst ialkali metal sulfate, uye catalyst yakagadzirwa ne diatomaceous earth yakanatswa. Kuedza kwakaratidza kuti SiO2 ine simba rekudzikamisa zvinhu zvinoshanda uye inowedzera nekuwedzera kwehuwandu hweK2O kana Na2O. Basa re catalyst rine chekuitawo nekupararira uye chimiro che pore che catalyst. Mushure mekurapa neacid ye diatomaceous earth, huwandu hwe oxide disadvantages hunoderera, huwandu hweSiO2 hunowedzera, uye nzvimbo chaiyo yepamusoro uye huwandu hwe pore hunowedzerawo. Nokudaro, mhedzisiro ye catalyst ye diatomaceous earth yakanatswa iri nani pane ye natural diatomaceous earth.

Nyika yeDiatomaceous inowanzo umbwa kubva muzvisaririra zvesilicate mushure mekufa kwealgae ine cell imwe chete, inozivikanwa sediatoms, uye hunhu hwayo iSiO2 isina morphous yemvura. Diatoms dzinogona kurarama mumvura yakachena nemumunyu, dzine mhando dzakasiyana. Dzinowanzo kamurwa kuita diatoms dze "central order" uye diatoms dze "feathered order", uye imwe neimwe ine "genera" dzakawanda dzakaoma kunzwisisa.

Chinhu chikuru chiri muvhu rema "diatomaceous earth" iSiO2, ine mhando yepamusoro ine ruvara ruchena uye huwandu hweSiO2 hunowanzo pfuura 70%. Ma "single diatoms" haana ruvara uye akajeka, uye ruvara rwevhu rema "diatomaceous earth" runoenderana nemaminerari evhu ne "organic matter". Maumbirwo evhu rema "diatomaceous earth" anobva muzvicherwa zvakasiyana-siyana anosiyana.

Nyika yeDiatomaceous, inozivikanwawo sediatom, idura rema diatom rakaumbwa mushure mekufa kwemuti mumwe chete une sero uye nguva yekuiswa kwemiti iyi inosvika makore chiuru kusvika zviuru zviviri. MaDiatoms aive chimwe chezvisikwa zvekutanga kuonekwa panyika, zvichigara mumvura yegungwa kana mumvura yedziva.

Rudzi urwu rwevhu remadiatomaceous runoumbwa nekuiswa kwezvisaririra zvemadiatomu emiti yemumvura ine sero rimwe chete. Kushanda kwakasiyana kwediatomu iyi ndekwekuti inogona kupinza silicon yakasununguka mumvura kuti igadzire mapfupa ayo. Kana hupenyu hwayo hwapera, inoisa uye inoumba madhipoziti evhu remadiatomaceous pasi pemamiriro ezvinhu epasi. Ine zvimwe zvinhu zvakasiyana, zvakaita semaburi, huwandu hushoma, nzvimbo yakakura chaiyo, kusagadzikana, uye kugadzikana kwemakemikari. Mushure mekuchinja kugoverwa kwehukuru hwezvimedu uye hunhu hwepamusoro hwevhu rekutanga kuburikidza neprocMaitiro ekuongorora akadai sekupwanya, kurongedza, kukora, kupatsanura mhepo, uye kubvisa tsvina, inogona kukodzera zvinodiwa zvakasiyana-siyana zvemaindasitiri zvakaita sekuputira uye zvekuwedzera pendi.
