Feldspar ndi imodzi mwa mchere wofunika kwambiri wopanga miyala padziko lapansi. Feldspar yokhala ndi potaziyamu kapena sodium yambiri imagwiritsidwa ntchito kwambiri mu zinthu zadothi, enamel, galasi, abrasives, ndi mafakitale ena. Potassium feldspar, chifukwa cha potaziyamu wambiri komanso kukhala gwero la potaziyamu yosasungunuka m'madzi, ingagwiritsidwe ntchito mtsogolo popanga feteleza wa potashi, zomwe zimapangitsa kuti ikhale gwero lofunika kwambiri la mchere. Feldspar yokhala ndi zinthu zosowa monga rubidium ndi cesium ikhoza kukhala gwero la mchere wochotsera zinthuzi. Feldspar yokhala ndi utoto wokongola ingagwiritsidwe ntchito ngati miyala yokongoletsera komanso miyala yamtengo wapatali.
Kupatula kukhala zinthu zopangira magalasi (zomwe zimagwiritsa ntchito pafupifupi 50-60% ya zonse zomwe zimagwiritsidwa ntchito), feldspar imagwiritsidwanso ntchito mumakampani opanga zinthu zadothi (30%), ndipo zina zonse zimagwiritsidwa ntchito mu mankhwala, zopukutira, fiberglass, ma electrode olumikizirana, ndi mafakitale ena.
Kutuluka kwa Galasi
Feldspar ndi chimodzi mwa zigawo zazikulu za magalasi osakaniza. Ndi kuchuluka kwa Al₂O₃ komanso chitsulo chochepa, feldspar imasungunuka kutentha kochepa ndipo imatha kusungunuka kwambiri. Imagwiritsidwa ntchito makamaka kuwonjezera kuchuluka kwa alumina mu magalasi osakaniza, kuchepetsa kutentha kosungunuka, ndikuwonjezera kuchuluka kwa alkali, motero kuchepetsa kuchuluka kwa alkali yomwe imagwiritsidwa ntchito. Kuphatikiza apo, feldspar imasungunuka pang'onopang'ono kukhala galasi, kuletsa mapangidwe a makhiristo omwe angawononge chinthucho. Feldspar imathandizanso kulamulira kukhuthala kwa galasi. Nthawi zambiri, potaziyamu kapena sodium feldspar imagwiritsidwa ntchito mu mitundu yosiyanasiyana ya magalasi osakaniza.
Zosakaniza za Thupi la Ceramic
Feldspar isanayambe kuwotcha, imagwira ntchito ngati chinthu chochepetsera kuuma, kuchepetsa kuchepa kwa kuuma ndi kusintha kwa thupi, kukonza magwiridwe antchito ouma, komanso kuchepetsa nthawi youma. Pakuwotcha, feldspar imagwira ntchito ngati flux yochepetsera kutentha kwa kuwotcha, kulimbikitsa kusungunuka kwa quartz ndi kaolin, komanso kuthandizira kupangidwa kwa mullite mu gawo lamadzimadzi. Galasi la feldspar lomwe limapangidwa panthawi yosungunuka limadzaza tinthu ta kristalo ta mullite m'thupi, zomwe zimapangitsa kuti zikhale zokhuthala komanso kuchepetsa porosity, motero zimawonjezera mphamvu yake yamakina ndi mphamvu zake zamagetsi. Kuphatikiza apo, kupangidwa kwa galasi la feldspar kumawonjezera kunyezimira kwa thupi. Kuchuluka kwa feldspar komwe kumawonjezeredwa m'mabomba a ceramic kumasiyana malinga ndi zipangizo zopangira ndi zofunikira za malonda.
Ceramic Glaze
Ma ceramic glaze amapangidwa makamaka ndi feldspar, quartz, ndi dongo, ndipo kuchuluka kwa feldspar kumayambira pa 10-35%. Mu makampani opanga ma ceramics (thupi ndi ma glaze), potassium feldspar imagwiritsidwa ntchito kwambiri.
Katundu Wathupi ndi Mankhwala
Feldspar ndi mchere womwe umapezeka kwambiri padziko lapansi, wokhala ndi potaziyamu yambiri yotchedwa potassium feldspar, yomwe imayimiridwa ndi mankhwala otchedwa KAlSi₃O₈. Orthoclase, microcline, ndi sanidine zonse ndi mchere wa potassium feldspar. Ma feldspar awa ali ndi kukhazikika kwabwino kwa mankhwala ndipo nthawi zambiri amalimbana ndi kuwonongeka kwa asidi. Ali ndi kuuma kwa 5.5-6.5, mphamvu yake ya 2.55-2.75 t/m³, komanso kutentha kwa 1185-1490°C. Michere yodziwika bwino ndi monga quartz, muscovite, biotite, beryl, garnet, ndi magnetite, columbite, ndi tantalite pang'ono.
Kugawa kwa Ma Deposits a Feldspar
Ma depositi a Feldspar amagawidwa m'magulu awiri kutengera mtundu wawo:
1. **Gneiss kapena Migmatitic Gneiss**: Mitsempha ina imapezeka mu granite kapena miyala yoyambira, kapena m'malo omwe imalumikizana. Mcherewu umakhala makamaka mu feldspar block zone ya pegmatites kapena feldspar pegmatites yosiyana.
2. **Miyala ya Igneous Type Feldspar Deposits**: Miyala iyi imapezeka m'miyala ya igneous ya acidic, yapakatikati, komanso ya alkaline. Yomwe imapezeka m'miyala ya alkaline ndiyofunika kwambiri, monga nepheline syenite, kutsatiridwa ndi granite, albite granite, orthoclase granite, ndi quartz orthoclase granite deposits.
Kutengera njira yopangira mchere ya feldspar, malo osungiramo feldspar amagawidwa m'mitundu ya miyala ya igneous, mtundu wa pegmatite, mtundu wa granite wogwa, ndi mtundu wa miyala ya sedimentary, ndipo mitundu ya miyala ya pegmatite ndi igneous ndiyo ikuluikulu.
Njira Zopatukana
- **Kusanja ndi Manja**: Kutengera kusiyana koonekeratu kwa mawonekedwe ndi mtundu kuchokera ku mchere wina wa gangue, kusanja ndi manja kumagwiritsidwa ntchito.
- **Kulekanitsa Magnetic**: Pambuyo pophwanya ndi kupukuta, zida zolekanitsa maginito monga ma plate magnetic separator, ma LHGC vertical ring high gradient magnetic separator, ndi ma HTDZ electromagnetic slurry magnetic separator amagwiritsidwa ntchito kuchotsa chitsulo cha maginito chofooka, titaniyamu, ndi mchere wina wodetsedwa kuti ayeretsedwe.
- **Flotation**: Amagwiritsa ntchito kwambiri HF acid m'malo okhala ndi asidi, ndi ma amine cations ngati zosonkhanitsira zolekanitsa feldspar ndi quartz.
Kuti mudziwe zambiri za Huate magnetic separator ndi momwe angathandizire pakuyeretsa ndi kulekanitsa feldspar ndi mchere wina, pitani patsamba lathu. Huate Magnetic Separator imapereka njira zamakono zolekanitsira maginito zomwe zimagwirizana ndi zosowa zanu zamafakitale.
