Kodi Diatomite ndi chiyani?

Diatomite ndi mwala wachilengedwe wa siliceous sedimentary womwe umapangidwa makamaka ndi zotsalira za ma diatomu akale, zomwe zimakhala ndi zinthu monga kutseguka kwambiri, kulowetsedwa, ndi kusefedwa. Gawo lalikulu la diatomite ndi amorphous silicon dioxide (SiO₂), yomwe nthawi zambiri imakhala ndi zonyansa zopitilira 80% ndipo imafika mpaka 94%, pomwe imakhala ndi zinthu zochepa monga Al₂O₃, Fe₂O₃, CaO, MgO, ndi zinthu zachilengedwe. Kapangidwe kapadera ka Diatomite ndi mankhwala kapangitsa kuti ikhale chinthu chofunikira kwambiri m'mafakitale osiyanasiyana padziko lonse lapansi, ndi ntchito zake zomwe zimagwiritsa ntchito tsiku ndi tsiku, kupanga mafakitale, komanso kuteteza chilengedwe.

1. Kupangidwa kwa Diatomite: Chozizwitsa cha Dziko Chomwe Chinapangidwa ndi Moyo Wakale ndi Nthawi

Gawo lalikulu la diatomite ndi makoma a maselo a siliceous (frustules) a ma diatom akale—algae ang'onoang'ono omwe ankakhala m'nyanja, m'nyanja, ndi m'madzi ena. Pa nthawi ya moyo wawo, zamoyozi zinkatulutsa silika yosungunuka m'madzi kuti zimange makoma awo ovuta komanso obowola. Pamene ma diatom ankafa, mafupa awo a silica ankakhazikika pansi pa madzi, n’kusonkhanitsa zinthu zambiri. Pansi pa kutentha, kupanikizika, ndi mikhalidwe ya geological kwa zaka mamiliyoni ambiri, zinthu zimenezi zinkapindika ndi kufalikira, n’kusanduka mwala wofewa, wofanana ndi choko womwe timautcha diatomite. Panthawiyi, kapangidwe kake ka ma diatom frustules kobowola kanasungidwa, motero kuyika maziko a makhalidwe apadera a diatomite.

Masiku ano, malo abwino kwambiri opangira ma diatomite akugawidwa padziko lonse lapansi. Madera akuluakulu opangira ma diatomite ndi United States, China, Denmark, Japan, France, ndi Mexico. China ili pa nambala yachiwiri padziko lonse lapansi m'malo osungira ma diatomite, ndipo malo akuluakulu amapezeka kumpoto chakum'mawa kwa China (Jilin Changbai Mountain), Xinle (Hebei), madera akum'mawa, Panxi (Sichuan), ndi kum'mawa ndi kumwera chakumadzulo kwa Yunnan. Malo amenewa amasiyana mu kapangidwe ka mchere ndi njira zokonzera (zomwe zimagawidwa ngati imvi yaiwisi diatomite, yellow calcined diatomite, ndi white flux-calcined diatomite), koma zonse zimasunga mawonekedwe apakati a diatomite—kuchuluka kwa porosity ndi mphamvu yoyamwa yomwe imachokera ku kapangidwe kovuta ka ma diatomite opangidwa ndi zinthu zakale.
