Isanti yeQuartz sisixhobo esibalulekileyo seminerali esisetyenziswa kwimizi-mveliso esineendlela ezahlukeneyo zokusetyenziswa, kubandakanya iglasi, ukubumba, iseramikhi kunye nezinto ezichasene ne-refractory, i-metallurgy, ulwakhiwo, iikhemikhali, iplastiki, irabha, i-abrasive kunye nezinye iimizi-mveliso. Ngaphezu koko, isanti yeQuartz ephezulu ikwadlala indima ebalulekileyo kulwazi lwe-elektroniki, i-optical fiber, i-photovoltaic kunye nezinye iimizi-mveliso, kunye nakwimizi-mveliso yokhuselo kunye neyomkhosi, i-aerospace kunye nezinye iintsimi. Kunokuthiwa iinkozo ezincinci zesanti zixhasa amashishini amakhulu. (I-vertical ring high gradient magnetic separator)
Okwangoku, zeziphi iintlobo zesanti ye-quartz ozaziyo?
01 Isanti yeQuartz yeenkcukacha ezahlukeneyo
Iinkcukacha eziqhelekileyo zesanti ye-quartz ziquka: 0.5-1mm, 1-2mm, 2-4mm, 4-8mm, 8-16mm, 16-32mm, 10-20, 20-40, 40-80, 80-120, 100-200, 200 kunye ne-325.
Inani le-mesh yesanti ye-quartz libhekisa kubungakanani bengqolowa okanye ubuncinci besanti ye-quartz. Ngokubanzi, libhekisa kwisikrini esikummandla we-intshi eyi-1 X 1 intshi. Inani lemingxuma ye-mesh enokudlula kwisikrini lichazwa njengenani le-mesh. Okukhona inani le-mesh yesanti ye-quartz likhulu, kokukhona ubungakanani bengqolowa yesanti ye-quartz buncinci. Okukhona inani le-mesh lincinci, kokukhona ubukhulu bengqolowa yesanti ye-quartz bukhulu.
02 Isanti yeQuartz yomgangatho owahlukileyo
Ngokubanzi, isanti ye-quartz ingabizwa ngokuba yi-quartz sand kuphela ukuba ine-silicon dioxide eyi-98.5% ubuncinane, ngelixa umxholo ongaphantsi kwe-98.5% ubizwa ngokuba yi-silica.
Umgangatho wengingqi wePhondo lase-Anhui DB34/T1056-2009 “isanti yeQuartz” usebenza kwisanti ye-quartz yemizi-mveliso (ngaphandle kwesanti ye-silica ephoswayo) eyenziwe ngelitye le-quartz ngokusila.
Emva kweminyaka yophuhliso, okwangoku, isanti ye-quartz idla ngokwahlulwahlulwa ibe yisanti ye-quartz eqhelekileyo, isanti ye-quartz ecociweyo, isanti ye-quartz ecocekileyo kakhulu, isanti ye-quartz exutyiweyo kunye nomgubo we-silica kushishino.
Isanti eqhelekileyo ye-quartz
Ngokubanzi, sisixhobo sokucoca amanzi esenziwe nge-quartz ore yendalo emva kokutyumza, ukuhlamba, ukomisa kunye nokuhlolwa kwesibini; i-SiO2 ≥ 90-99%, i-Fe2O3 ≤ 0.06-0.02%. Esi sixhobo sokucoca siphawulwa kukungabikho kokulungiswa kwe-engile, uxinano oluphezulu, amandla aphezulu oomatshini, kunye nobomi benkonzo ende yomgca wokuthwala ungcoliseko. Sisixhobo sokucoca amanzi ngamakhemikhali. Singasetyenziswa kwi-metallurgy, i-graphite silicon carbide, iimveliso zeglasi kunye neglasi, i-enamel, intsimbi ephosiweyo, i-caustic soda, iikhemikhali, ingxolo yejethi kunye neminye imboni.

03 Isanti yeQuartz ngeenjongo ezahlukeneyo
Isanti yesinyithi esiphantsi seglasi ye-photovoltaic (i-magnetic drum magnetic separator)
Iglasi ye-Photovoltaic isetyenziswa ngokubanzi njengephaneli yokupakisha yeemodyuli ze-photovoltaic, ezidibana ngqo nokusingqongileyo kwangaphandle. Ukumelana kwayo nemozulu, amandla, ukuhanjiswa kokukhanya kunye nezinye izalathisi zidlala indima ebalulekileyo ekusebenzeni kakuhle kokuvelisa umbane ixesha elide kunye nokusebenza kakuhle kwexesha elide kweemodyuli ze-photovoltaic. I-ion yesinyithi kwisanti ye-quartz kulula ukuyidaya. Ukuqinisekisa ukuhanjiswa okuphezulu kwelanga kweglasi yokuqala, umxholo wesinyithi kwiglasi ye-photovoltaic kufuneka ube ngaphantsi kunoweglasi eqhelekileyo, kwaye kufuneka kusetyenziswe isanti ye-quartz yesinyithi esincinci esinobumsulwa obukhulu be-silicon kunye nomxholo wokungcola okuphantsi.
Isanti ye-quartz ecocekileyo kakhulu ye-photovoltaic
Ukuveliswa kwamandla e-solar photovoltaic kuye kwaba yindlela ekhethwayo yokusetyenziswa kwamandla elanga, kwaye isanti ye-quartz ecocekileyo kakhulu inesicelo esibalulekileyo kwishishini le-photovoltaic. Izixhobo ze-quartz ezisetyenziswa kwishishini le-photovoltaic ziquka ii-quartz ceramic crucibles zee-solar silicon ingots, kunye nee-quartz boats, ii-quartz furnace tubes kunye nee-boat brackets ezisetyenziswa kwinkqubo yokusasazwa kunye ne-oxidation yenkqubo yokwenziwa kwe-photovoltaic, kunye nenkqubo ye-PECVD. Phakathi kwazo, ii-quartz crucibles zahlulwe zaba zii-square quartz crucibles zokukhulisa i-polycrystalline silicon kunye nee-round quartz crucibles zokukhulisa i-monocrystalline silicon. Zezona zinto zisetyenziswayo ngexesha lokukhula kwee-silicon ingots kwaye zezona zixhobo ze-quartz ezifunwa kakhulu kwishishini le-photovoltaic. Izinto eziphambili ze-quartz crucible yisanti ye-quartz ecocekileyo kakhulu.
Isanti yepleyiti
Ilitye le-quartz lineempawu zokungagugi, ukumelana nokukrweleka, ukumelana nobushushu, ukumelana nokugqwala kunye nokuqina. Liqinile kwaye lisetyenziswa kakhulu. Liyimveliso esemgangathweni kwimbali yophuhliso lwezixhobo zokwakha ezenziweyo. Liye kancinci kancinci laba yinto entsha ethandwayo kwimarike yokuhombisa ikhaya kwaye lithandwa ngabathengi. Ngokubanzi, i-95% ~ 99% yesanti ye-quartz okanye umgubo we-quartz ubotshelelwe kwaye uqiniswe yi-resin, i-pigment kunye nezinye izongezo, ngoko ke umgangatho wesanti ye-quartz okanye umgubo we-quartz umisela ukusebenza kwepleyiti yelitye le-quartz eyenziweyo ukuya kwinqanaba elithile.
Umgubo wesanti we-quartz osetyenziswa kwishishini le-quartz plate uhlala ufunyanwa kwi-quartz vein kunye ne-quartzite ore ekumgangatho ophezulu ngokutyumza, ukuhluza, ukuhlukana kwemagnethi kunye nezinye iinkqubo. Umgangatho wezinto eziluhlaza uchaphazela ngokuthe ngqo umgangatho we-quartz. Ngokubanzi, i-quartz esetyenziselwa i-quartz stone slab yahlulwe yaba yi-quartz sand powder entle (5-100 mesh, esetyenziswa njenge-aggregate, i-aggregate idla ngokufuna umxholo we-≥ 98% we-silicon) kunye ne-quartz sand coarse (320-2500 mesh, esetyenziselwa ukuzalisa nokuqinisa). Kukho iimfuno ezithile zobunzima, umbala, ukungcola, ukufuma, ubumhlophe, njl.
Isanti yeFoundry
Ngenxa yokuba i-quartz inokumelana nomlilo okuphezulu kunye nobunzima, kwaye ukusebenza kwayo okuhle kakhulu kwezobuchwepheshe kunokuhlangabezana neemfuno ezahlukeneyo ezisisiseko zemveliso yokubumba, ayinakusetyenziswa kuphela ekubumbeni isanti yodongwe yendabuko, kodwa nakwinkqubo eziphambili zokubumba kunye nokwenza isiseko esifana nesanti yeresin kunye nesanti egqunyiweyo, ngoko ke isanti ye-quartz isetyenziswa kakhulu kwimveliso yokubumba.
