Chiyambi cha kusefera kwa zidindo

Zomwe zimatchedwa kusefera kwa pre-№ ndi kuwonjezera kuchuluka kwa chithandizo cha fyuluta muzosefera, ndipo pakapita nthawi yochepa, kusungunula kosasunthika kokhazikika kumapangidwira pazitsulo zosefera, zomwe zimasandutsa kusefera kosavuta kwapa media kukhala kusefera kozama, zomwe zimapangitsa kuyeretsa Kwamphamvu ndi kusefa. Zothandizira zosefera zomwe zimagwiritsidwa ntchito nthawi zambiri ndi perlite, cellulose, diatomaceous earth, carbon black ndi asibesitosi. Zothandizira zosefera za Diatomite zakhala zikugwiritsidwa ntchito kwambiri chifukwa cha zabwino zake zonse pakuchita, mtengo, gwero ndi zina.

Mfundo ya pre-coating filtration

Pampu ya fyuluta imagwiritsidwa ntchito podutsa kuyimitsidwa komwe kuli ndi chithandizo cha fyuluta mu thanki ya fyuluta, ndipo pakapita nthawi yozungulira, chithandizo cha fyuluta chimayikidwa pamwamba pa fyuluta sing'anga kupanga fyuluta isanayambe kupaka wosanjikiza ndi pores zovuta komanso zabwino. Chifukwa cha kukhalapo kwa ❖ kuyanika, kulondola kwapamwamba kwa kusefedwa kumapezedwa poyambira gawo lotsatira la kusefera, komanso kutha kuletsa tinthu tating'ono kuti tisatseke pores za chinthu chosefera. Panthawi yosefera, tinthu tating'onoting'ono takuyimitsidwa timasakanizidwa ndi tinthu tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono tomwe timawonjezera pang'onopang'ono kenako ndikuunjikana pagawo la fyuluta kuti mupange keke yotayirira, kotero kuti kusefera kumakhala kokhazikika.

Makhalidwe a diatomite fyuluta aid

Zothandizira zosefera za Diatomite zimabwera mumitundu yosiyanasiyana. Chigawo chake chachikulu ndi khoma la porous siliceous chipolopolo. Zizindikiro zazikulu za ntchito ndi kukula kwa tinthu, kachulukidwe kachulukidwe, malo enieni, ndi chigawo chimodzi. Pakati pawo, kugawidwa kwa tinthu tating'ono ndi chimodzi mwa zizindikiro zofunika kwambiri zogwirira ntchito. Imatsimikizira mwachindunji kukula kwa pores fyuluta ndi kugawa kwa micropores. Tinthu tating'onoting'ono tating'onoting'ono timakhala ndi madzi abwinoko, koma kusefera kolondola kumakhala kotsika, kotero kuchuluka kwakuyenda kofunikira komanso kusefera kumayenera kukumana. , Sankhani makulidwe oyenera a dziko la diatomaceous. Zopangidwa m'nyumba zimagawidwa m'mitundu iwiri ya makulidwe, yomwe ingagwiritsidwe ntchito yokha kapena kuphatikiza ndi makulidwe osiyanasiyana ndi kukula kwa tinthu kuti tipeze kulondola kwambiri kusefera. Kuchulukirachulukira kwa diatomite kumakhalanso ndi chikoka chachikulu pa kusefa. Kachulukidwe kakang'ono kachulukidwe, kuchuluka kwa pore kwa tinthu tating'onoting'ono ta zosefera, komanso ma permeability ake ndi ma adsorption kuyenera kuyendetsedwa panthawi yakuphimba. Kuphatikizika kwa diatomite yapakatikati ndi kuchuluka kwa kufalikira kwa njira yophikirapo kale kumathandizira kuti tinthu tating'ono ta diatomite tigwirizane ndi mapangidwe a yunifolomu yoyambira. Kuchulukira kwa diatomite nthawi zambiri kumakhala 0.3 mpaka 0.6%, ndipo kuthamanga kozungulira kumatha kukhazikitsidwa 1 mpaka 2 kuchuluka kwanthawi zonse. Kuthamanga kwa pre-coating nthawi zambiri kumakhala pafupifupi 0.1MPa.
