Kusefa ndi njira yodziwika bwino yochizira thupi yomwe imagwiritsidwa ntchito kuchotsa zinthu zosasungunuka m'madzimadzi. Chifukwa chakuti zinthu zolimba zomwe zili m'madzimadzi nthawi zambiri zimakhala tinthu tating'onoting'ono tomwe timakhala tosalala, topanda mawonekedwe, tomata, komanso tosavuta kutseka mabowo a nsalu yosefera, ngati zosefedwa padera, mavuto monga kuvutika kusefera ndi kusefera kosadziwika nthawi zambiri amabuka, zomwe sizingagwiritsidwe ntchito pochita. Ngati chothandizira chosefera chawonjezeredwa ku yankho kapena wosanjikiza wa chothandizira chosefera waphimbidwa kale pamwamba pa nsalu yosefera, zitha kusintha kwambiri vutoli. Liwiro losefera ndi lachangu, chosefera chimakhala choyera, ndipo zotsalira za chosefera zimakhala zolimba, zomwe zimatha kuchoka pa nsalu yosefera. Chothandizira chosefera chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana ndi diatomaceous earth. Ndicho chomwe nthawi zambiri timatcha diatomaceous earth filter aids.

Chothandizira pa fyuluta ya Diatomaceous earth ndi mtundu watsopano wa fyuluta yopangidwa bwino kwambiri yopangidwa ndi kukonzedwa pogwiritsa ntchito diatomaceous earth ngati zinthu zoyambira kudzera mu njira zosungira zotsekedwa monga kukonza, kusanja, kugawa, kugawa, ndi kugawa. Imatha kupanga keke yolimba ya fyuluta, yomwe imatha kuletsa tinthu tating'onoting'ono mu madzi oyambira kusefedwa kukhala zonyansa za colloidal pa mafupa a latisi. Chifukwa chake, imakhala ndi kulowerera bwino ndipo imapereka kapangidwe ka keke yosefedwa yokhala ndi mabowo, yokhala ndi mabowo a 85-95%, yomwe imatha kupeza chiŵerengero cha kuthamanga kwa madzi pogawa cholimba ndi chamadzimadzi, ndipo imatha kusefa zinthu zolimba zoyimitsidwa. Chothandizira pa fyuluta ya Diatomaceous earth chimakhala ndi kukhazikika kwabwino kwa mankhwala ndipo chingagwiritsidwe ntchito modalirika kusefa madzi aliwonse kupatulapo yankho lolimba la caustic. Sizidetsa madzi osefedwa ndipo zimagwirizana ndi zofunikira za Lamulo la Ukhondo wa Chakudya. Ndipo ingagwiritsidwe ntchito mokwanira pazipangizo monga nsalu yosefedwa, pepala yosefedwa, maukonde achitsulo, ziwiya zadothi, ndi zina zotero. Imatha kupeza zotsatira zabwino zosefera pamakina osiyanasiyana osefedwa ndipo ili ndi ubwino wazipangizo zina zosefera. Kugwiritsa ntchito zida zothandizira za diatomaceous earth filter kukufalikira kwambiri. Kumagwiritsidwa ntchito m'makampani popanga zinthu zosefera. Kumagwiritsidwa ntchito m'makampani opanga chakudya posefera mowa, madzi osambira, madzi a zipatso, zakumwa zosiyanasiyana, manyuchi, mafuta a masamba, kukonzekera ma enzyme, citric acid, ndi zina zotero. Kumagwiritsidwa ntchito m'makampani opanga mankhwala posefera utoto, zokutira, electroplating, solvents, acids, electrolytes, ma resin opangidwa, ulusi wa mankhwala, glycerol, emulsion, ndi zina zotero. Kumagwiritsidwa ntchito m'makampani opanga mankhwala posefera maantibayotiki, shuga, ndi mankhwala achikhalidwe aku China. Ponena za kuteteza chilengedwe, imagwiritsidwa ntchito poyeretsa madzi m'mizinda, madzi osambira, zimbudzi, madzi otayira m'mafakitale, ndi zina zotero.

1、 Diatomaceous earth filter aid: Ndi mtundu wa diatomaceous earth filter aid womwe umapangidwa kudzera mu kuumitsa, kusungunuka, kuwononga, ndi kugawa, zomwe zingagwiritsidwe ntchito pogawa mitundu yosiyanasiyana ya madzi ndi olimba. Mitundu yosiyanasiyana ya diatomaceous earth filter aid imasankhidwa pogawa mitundu yosiyanasiyana ya madzi ndi olimba. Amagwiritsidwa ntchito kwambiri pokonzekera. Magulu ambiri amagwiritsa ntchito kapangidwe ka mapokoso a diatomaceous earth ndi silika shells. Pokonza, chisamaliro chiyenera kuperekedwa pakusunga kapangidwe ndi mawonekedwe apadera a mafupa a diatomaceous, kusankha mosamala zida zoyenera zophwanyira ndi kupukusa komanso mikhalidwe yaukadaulo, ndikusunga umphumphu wa kapangidwe ka diatomaceous momwe zingathere kuti tipewe kugawikana kwachiwiri. Zipangizo zopukusa zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala chosokoneza mpweya.
2、 Ntchito zitatu zofunika kwambiri za diatomaceous earth filter aid ndi izi: 1. Screening effect. Iyi ndi surface filtration effect. Pamene madzi akuyenda mu diatomaceous earth, ma pores a diatomaceous earth amakhala ang'onoang'ono kuposa kukula kwa tinthu tating'onoting'ono ta tinthu tating'onoting'ono, kotero tinthu tating'onoting'ono sitingadutse ndipo timagwidwa. Izi zimatchedwa screening effect. 2. Pakusefa mozama, njira yolekanitsa imachitika mkati mwa medium, ndipo tinthu tating'onoting'ono tomwe timadutsa pamwamba pa fyuluta ya keke timatsekedwa ndi ma pores mkati mwa diatomaceous earth. Kuthekera kosefa tinthu tating'onoting'ono kumagwirizana kwambiri ndi kukula ndi mawonekedwe a tinthu tating'onoting'ono ndi ma pores.
3, Kulowetsedwa kwa madzi kumatanthauza kupangika kwa magulu a unyolo pakati pa tinthu tomwe timakokedwa ndi ma charge otsutsana, motero kumamatira mwamphamvu ku dziko lapansi la diatomaceous.
