Thekuchotsedwa kwa mzere wolembedwaZosefera za magnetite zimawonjezera kukana kovala ndi 20 ~ 35% poyerekeza ndi zinthu wamba zosefera za magnetite.Atha kutanthauza zomwe zachitika bwino m'munda, kuphatikiza kafukufuku ndi kukwezedwa kwa zosefera zosanjikiza zitatu zosanjikiza, bedi la fyuluta yamitundu itatu yosanjikiza, zosefera za magnetite zosankhidwa kuchokera ku miyala yosowa kopitilira muyeso ya metamorphic, ndi poizoni Makhansa ena obwera chifukwa cha zitsulo zolemera alandira chidwi chofala kuchokera kwa anthu osamalira madzi kunyumba ndi kunja.Ngati zinyalala zokhala ndi mphamvu yokoka pang'ono kapena zosayenerera zikugwiritsidwa ntchito, kusinthika kwa turbidity kapena kusinthasintha kwamadzi m'madzi kumalimbikitsidwa.Zinyalala monga dzimbiri ndi sikelo zitha kuchotsedwa.The fyuluta zakuthupi ndi yaing'ono tinthu kukula ndi lalikulu enieni yokoka amagawidwa m'munsi wosanjikiza.Kulemba chizindikiro kuchotsa kumapangitsa kuti kusefedwa kufulumizitse, ndipo kumapangitsa kuti kukhale kovuta kwambiri kukwaniritse zofunikira zina, kugawa tinthu ting'onoting'ono, fumbi lochepa, mchere wosungunuka (kloridi) ndi kutsika kwambiri, kuphulika kwakukulu kwa malo ndi malo a unit panthawi imodzi. ndipo imakwaniritsa zofunikira zaukadaulo zamafakitale ndi zankhondo.

1. Ndipamwamba kwambiri, koyera zachilengedwe zopanda zitsulo sandblasting abrasive.Kuphatikiza apo, malinga ndi momwe zinthu ziliri, zitsulo zosapanga dzimbiri zidzatsukidwanso mchenga kuti ziyeretsedwe pamaso pa pickling ndi passivation.Fumbi ndilochepa kwambiri, ndipo madontho a mafuta omwe angakhalepo pamwamba amachotsedwa, 2g / cm3, ngodya zake ndi zakuthwa, ndipo ubwino wa madzi ndi wabwino.Popanga mawonekedwe a bedi la fyuluta, mphamvu yokoka ndi chitsulo ndipamwamba kwambiri, kotero kuti pamakhala fumbi lochepa pophulika, ndi zosefera zomwe zimakhala ndi mphamvu yokoka pakati pa tinthu tating'onoting'ono zimagawidwa pakati, ndipo zimakhala ndi FeTiO3 ( imafotokozedwanso ngati FeOTiO2), yomwe ingachepetsenso ndalama.

2. Malo ogwirira ntchito adzakhala abwino kuposa mchenga wa quartz.Momwe mungasankhire zinthu zosefera Momwe mungasankhire zinthu zosefera ndi kukula kwakukulu kwa tinthu ndi mphamvu yokoka yaying'ono imagawidwa mumtunda wapamwamba, kapena kukwaniritsa cholinga china chaumisiri kapena kupanga matte pamwamba kuti muchepetse chiwonetsero, ndikuchotseratu sikelo, dzimbiri. , mchere wosungunuka ndi dothi lina.Pambuyo poyesa ndi kutsimikizira ndi kusintha, kuphwanya kwapang'onopang'ono kumakhala kochepa panthawi ya kuphulika, ndipo panthawi imodzimodziyo, kusefera kumakhala kwautali.Kutengera kugwiritsa ntchito, imatha kubwezeredwanso nthawi 5-10.Fyuluta iyi ili ndi mphamvu yayikulu yolumikizira dothi, 5-8.Chifukwa chake nthawi yosefera ndi yayitali,

3. Ukadaulo wosefera pa nthawi yoyeretsera zolembera zamakono nthawi zonse umangosintha zofunikira zachidziwitso, n'zosavuta kupanga zosefera ndi zinthu zapadding zosakanikirana mu ndondomeko ya backwashing, ndipo ndizoletsedwa kusuntha molimbika.Mzere wolembera umatsuka zowononga zoyera, zopanda mankhwala komanso zopanda fumbi za RZG garnet, ndipo zimasinthidwanso ndikugwiritsiridwa ntchitonso.Kusankha kwapamwamba kachulukidwe fyuluta magnetite monga pad n'kofunika kwambiri.Ilibe silicon yaulere, Zitsulo zolemera ndi zinthu zina zovulaza zimakhala ndi zotsatira zabwino kwambiri zodulira ndipo pang'onopang'ono zimakhala zazing'ono.

4. Bedi losefera la fyuluta lili ndi zigawo zitatu za zinthu zosefera.M'malo mwake, chifukwa cha zinthu zosefera zonyansa, kutuluka kwamadzi kwachipwirikiti, kukula kwa tinthu tating'onoting'ono tosiyanasiyana ndi mphamvu yokoka, ndi zina zotero, kumamatira kwamphamvu kwambiri komanso moyo wautali wakutira umakwaniritsidwa.Kuuma kwakukulu, kulimba kwambiri, kulimba kwabwino, ngodya zakuthwa komanso kulimba m'mphepete, malo opukutidwa ndi mchenga alibe zoyikapo, kotero kuti kuthekera kochotsa dothi la bedi la zosefera kutha kuchitidwa mokwanira, ndiye kuti, pafupifupi zinthu zitatu zosefera Kukula kwa tinthu ndi kuchokera pamwamba mpaka pansi.
