nkhani

Kuyika kwa zinthu zamatope za diatom pamsika nthawi zambiri kumawonetsa mawu oti "diatomite yopanda calcined" pazopangira. Kodi pali kusiyana kotani pakati pa non-calcined diatomite ndi calcined diatomite? Kodi ubwino wa non-calcined diatomaceous earth ndi chiyani? Onse calcination ndi osawerengetsa njira kuyeretsa dziko diatomaceous. Mwala wa Diatomaceous earth uli ndi zonyansa zambiri, choncho njira zingapo ziyenera kugwiritsidwa ntchito poyeretsa. Non-calcined amatanthauza dziko la diatomaceous lomwe silinawerengedwe kutentha kwambiri. Amatchedwanso madzi osamba diatomaceous earth. Ndi yosiyana ndi flux-calcined diatomaceous earth. Iwo otsukidwa ndi omwazika, sieved, supergravity munda laminar otaya centrifugal beneficiation, youma gulu, etc. Woyengeka diatomaceous lapansi anapezedwa ndi ndondomeko akhoza bwino kusanja ndi kuchotsa quartz, feldspar mchere, dongo ndi zina organic nkhani mu original diatomite ore, ndipo akhoza molondola m'magulu a wexizem zinchito dziko matanthwe matanthwe zinthu zachilengedwe. Dziko lapansi la diatomaceous limaphatikizapo malo okulirapo, porosity yayikulu, pore voliyumu yayikulu, kukula kocheperako, komanso mphamvu zowongolera komanso kuwongolera chinyezi.

Malinga ndi kuyerekezera kwa kuyamwa kwa chinyezi kwa ma diatomite awiriwa pansi pa malo omwewo omwe amapezedwa ndi kafukufuku wa labotale, zikuwonekeratu kuti mphamvu ya kuyamwa kwa chinyezi ya diatomite yopanda calcined ndi yapamwamba kangapo kuposa ya calcined diatomite. Kuchita kwa diatomite kudzakhudza kuthekera kwa zinthu zamatope za diatom kuti zigwire mamolekyu owopsa monga formaldehyde omwe ali opanda mlengalenga. Kugwiritsa ntchito diatomite sanali calcined kuonjezera malonda adsorption matope diatom kangapo, ngakhale kakhumi Koposa, malinga ndi mayesero angapo Hongyi sanali calcined diatom matope mankhwala ndi m'madipatimenti zogwirizana, formaldehyde kuyeretsedwa ntchito anafika 96%, 95%, 94%, ndi 92% motero, onse 90%. Sikovuta kuwona kuti kusintha kwa magwiridwe antchito a dziko lapansi losawerengeka la diatomaceous pazinthu zamatope za diatom ndizodziwikiratu.
