Feldspar ndeimwe yezvicherwa zvakakosha zvikuru zvinoumba matombo muvhu. Feldspar ine potassium yakawanda kana sodium inoshandiswa zvakanyanya muzvigadzirwa zveceramics, enamel, girazi, abrasives, nedzimwe nzvimbo dzemaindasitiri. Potassium feldspar, nekuda kwehuwandu hwayo hwakawanda hwe potassium uye kuva sosi ye potassium isinganyunguduke mumvura, inogona kushandiswa mune ramangwana kugadzira fetereza ye potash, zvichiita kuti ive sosi yakakosha yezvicherwa. Feldspar ine zvinhu zvisingawanzoonekwi zvakaita se rubidium ne cesium inogona kushanda sesosi yezvicherwa pakubvisa zvinhu izvi. Feldspar ine mavara akanaka inogona kushandiswa sedombo rekushongedza uye matombo anokosha zvishoma.
Kunze kwekuva chinhu chisina kugadzirwa muindasitiri yegirazi (ichiverengera 50-60% yekushandiswa kwese), feldspar inoshandiswawo muindasitiri yeceramics (30%), uye yasara inoshandiswa mumakemikari, abrasives, fiberglass, welding electrodes, uye mamwe maindasitiri.
Kuyerera kwegirazi
Feldspar chimwe chezvinhu zvikuru zvinoumba musanganiswa wegirazi. Nehuwandu hwakawanda hweAl₂O₃ uye huwandu hushoma hwesimbi, feldspar inonyunguduka patembiricha yakaderera uye ine huwandu hwakakura hwekunyunguduka. Inonyanya kushandiswa kuwedzera huwandu hwealumina mumisanganiswa yegirazi, kuderedza tembiricha yekunyunguduka, uye kuwedzera huwandu hwealkali, nokudaro ichideredza huwandu hwealkali inoshandiswa. Pamusoro pezvo, feldspar inonyunguduka zvishoma nezvishoma kuita girazi, ichidzivirira kuumbwa kwemakristaro anogona kukuvadza chigadzirwa. Feldspar inobatsirawo kudzora viscosity yegirazi. Kazhinji, potassium kana sodium feldspar inoshandiswa mumisanganiswa yakasiyana-siyana yegirazi.
Zvinhu zveCeramic Muviri
Feldspar isati yatanga kupiswa, inoshanda sezvinhu zvakachekwa, ichideredza kuoma kwemuviri, ichivandudza mashandiro ekuomesa, uye ichipfupisa nguva yekuomesa. Panguva yekupiswa, feldspar inoshanda senzira yekudzikisa tembiricha yekupiswa, ichikurudzira kunyunguduka kwequartz nekaolin, uye ichibatsira kuumbwa kwemullite muchikamu chemvura. Girazi refeldspar rinoumbwa panguva yekunyunguduka rinozadza mullite crystal grains mumuviri, zvichiita kuti ive yakakora uye inoderedza porosity, nokudaro ichiwedzera simba rayo remakanika uye hunhu hwe dielectric. Pamusoro pezvo, kuumbwa kwegirazi refeldspar kunowedzera kupenya kwemuviri. Huwandu hwefeldspar hunowedzerwa mu ceramic bodies hunosiyana zvichienderana nezvinhu zvakachekwa uye zvinodiwa zvechigadzirwa.
Ceramic Glaze
Ceramic glaze inonyanya kuumbwa nefeldspar, quartz, nevhu, ine feldspar iri pakati pe10-35%. Muindasitiri yeceramics (muviri negirazi), potassium feldspar ndiyo inonyanya kushandiswa.
Zvimiro zveMuviri neMakemikoro
Feldspar chicherwa chinowanikwa zvakanyanya pasi rose, chine potassium yakawanda inozivikanwa se potassium feldspar, inomiririrwa nemakemikari se KAlSi₃O₈. Orthoclase, microcline, uye sanidine zvese zvicherwa zve potassium feldspar. Zvicherwa izvi zvine kugadzikana kwakanaka kwemakemikari uye zvinowanzo ramba kuora kweasidhi. Zvine kuoma kwe5.5-6.5, giravhiti chaiyo ye 2.55-2.75 t/m³, uye poindi yekunyunguduka ye 1185-1490°C. Zvicherwa zvinowanzobatanidzwa zvinosanganisira quartz, muscovite, biotite, beryl, garnet, uye magnetite shoma, columbite, uye tantalite.
Kurongwa kweFeldspar Deposits
Mafeldspar deposits anonyanya kupatsanurwa kuita mhando mbiri zvichienderana nerudzi rwawo:
1. **Gneiss kana Migmatitic Gneiss**: Mimwe mitsipa inowanikwa mugranite kana mumatombo makuru, kana munzvimbo dzayo dzekubatana. Matombo aya anonyanya kuunganidzwa munzvimbo yefeldspar block yepegmatites kana differenated feldspar pegmatites.
2. **Matombo eIgneous Type Feldspar Deposits**: Madombo aya anowanikwa mumatombo eigneous ane acidic, intermediate, uye alkaline. Anowanikwa mumatombo ealkaline anonyanya kukosha, akadai se nepheline syenite, anoteverwa ne granite, albite granite, orthoclase granite, uye quartz orthoclase granite deposits.
Zvichibva pamaitiro ekugadzira zvicherwa zvefeldspar, madhaidhi efeldspar akakamurwa kuita mhando yedombo reigneous, mhando yepegmatite, mhando yegranite yakawa, uye mhando yedombo resedimentary, uye mhando dzedombo repegmatite nedombo reigneous dziri idzo huru.
Nzira dzekuparadzanisa
- **Kuronga Nemaoko**: Zvichibva pamusiyano uri pachena muchimiro neruvara kubva kune zvimwe zvicherwa zvegangue, kurongedza nemaoko kunoshandiswa.
- **Kupatsanurwa kweMagineti**: Mushure mekupwanya nekukuya, michina yekuparadzanisa magineti yakaita semaplate magnetic separator, maLHGC vertical ring high gradient magnetic separator, uye maHTDZ electromagnetic slurry magnetic separator anoshandiswa kubvisa simbi ine magnetic iron, titanium, nezvimwe zvicherwa zvisina kuchena kuti zvicheneswe.
- **Flotation**: Inonyanya kushandisa HF acid mumamiriro ezvinhu ane acidic, ine amine cations semuunganidzi wekuparadzanisa feldspar kubva ku quartz.
Kuti uwane rumwe ruzivo nezve Huate magnetic separator uye kuti vangabatsira sei mukuchenesa nekuparadzanisa feldspar nezvimwe zvicherwa, shanyira webhusaiti yedu. Huate Magnetic Separator inopa mhinduro dzepamusoro dzemagnetic separation dzakagadzirirwa zvaunoda muindasitiri.
