Izinto eziphambili zeglasi ye-photovoltaic zezi: isanti ye-silica, i-soda ash, i-dolomite, i-limestone, i-aluminium hydroxide, i-mirabilite, i-sodium nitrate, i-sodium pyroantimonate, kunye neglasi ephukileyo ephinde yasetyenziswa. Ngenxa yeemfuno ezikhethekileyo zokuhambisa ukukhanya kweglasi ye-photovoltaic, ngokubanzi kufuneka ukuba umxholo wentsimbi wento nganye eluhlaza ube phantsi, kwaye izinto eziluhlaza zibe yintsimbi ephantsi, ukuze kufumaneke ukuhambisa ukukhanya okuphezulu.
1. Isanti yeSilica, eyona nto iphambili kwiSilica, umgaqo wokukhetha umzi-mveliso ngokubanzi
11 Umxholo ophezulu weSiO2 kunye nozinzo.
1.2 Umxholo ophantsi we-Fe2O3 kunye ne-Al2O3 kwaye uzinzile.
1.3 Akukho masuntswana arhabaxa, njenge-chromite kunye nezinye izinto ezingcolisayo.
1.4 Ubungakanani obufanelekileyo bamasuntswana, akukho masuntswana makhulu kwaye kukho umgubo ocolekileyo omninzi kakhulu.
1.5 Umthamo wokufuma ozinzileyo.
Iimfuno zesalathiso ezithile
A. Ukwakheka kweekhemikhali:
| Umxholo | I-SiO2 | I-Al2O3 | I-Fe2O3 | I-LOI | Ukufuma |
| % | ≥99.3±(0.4) | ≤0.3±(0.1) | ≤0.008 | ≤0.15 | ≤5.0 |
Ukuba kukho indawo yokugcina amanzi ehambelanayo, ulawulo lwamanzi kunye nolawulo lunokukhululwa ngokufanelekileyo ukuze kuhlangatyezwane neemfuno zokondla kwindawo yokugcina amanzi ehambelanayo.
B. Ukusasazwa kwamasuntswana
| mm | 1.0 | 0.71 | 0.50 | 0.125 | -0.125 |
| % | Akukho | ≤Akukho | ≤5.0 | ≥90.0 | ≤10.0 |
Ngokuphathelele ukusasazwa kobukhulu bamasuntswana, ezinye iincwadi zibonisa ukuba umgangatho womgubo ocolekileyo unokuncitshiswa ngokufanelekileyo ukuya kwi-15%, kodwa uhlobo lwe-oven kufuneka luqwalaselwe. Ukuba yi-oven esebenza ngeoksijini yonke, inokuncitshiswa ngokufanelekileyo, ngelixa ukuba yi-oven yomoya, akufuneki incitshiswe, ukuze kuthintelwe iziphene zomgubo ocolekileyo ovala i-lattice kwaye ubhabhe ubangele iziphene ezimhlophe. Indawo yokunyibilika kwesanti ye-silica yi> 1800℃. Ukuba kukho amasuntswana amakhulu, imeko yokungancitshi inokwenzeka (kuxhomekeke kubungakanani bokutsalwa kunye nesantya sokunyibilika kwe-oven).
Okwangoku, imithombo ephambili yesanti yesilika yile: Indawo yaseFengyang, iPhondo laseAnhui, iWenchang, iPhondo laseHainan, iHepu, iBeihai, iZhanjiang, kunye nendawo yaseHeyuan. Amazwe angaphandle, okwangoku kukho isanti yaseIndonesia, yaseMalaysia, yaseVietnam kunye neyaseOstreliya. Kwifengyang kunye neHeyuan vein quartz ore umgangatho njengexesha lokugqibela lokucoca i-kaolin eyenziwe ngegravel etyumzayo kwakhona (umz., ihepu, isanti yaseZhanjiang), kwakhona isanti yolwandle (ikakhulu iqulethe i-titanium dioxide ayisusi okanye ayinciphise, i-oven inokhukuliseko oluthile, kwaye iintsalela ze-titanium dioxide kwiglasi zinokukhokelela ekudluliseleni ukukhanya kwe-UV phantsi).
2. I-soda yesoda, iifektri zeglasi ngokubanzi zikhetha i-heavy soda soda, eyona nto iphambili kwi-sodium carbonate, zidlala indima ekudibaniseni, ubuncinci bayo kunye nesanti ye-silica ibe ngulwalamano, iimfuno zefektri ngokubanzi zemigangatho yomgangatho wesoda yesoda kunye nemigaqo yokukhetha zezi zilandelayo:
2.1 Umxholo ophezulu we-Na2CO3
2.2 Umxholo ophantsi weNaCl kunye neFe2O3
2.3 Ubungakanani obufanelekileyo beesuntswana kwaye azinazo izinto ezingcolisayo neziqhotyoshelwa.
Iimfuno zesalathiso ezithile
A. Iimfuno zezithako:
| Umxholo | I-Na2CO3 | I-NaCl | Ilahleko | I-Fe2O3 |
| % | ≥99.0 | ≤0.50 | ≤0.50 | 0.0030 |
5. I-aluminium hydroxide, ikakhulu inika izixhobo ze-alumina, amandla eglasi ukuze kuphuculwe indima, kodwa umxholo ophezulu we-alumina unokukhokelela ekucacisweni kokunyibilika kwemeko embi, kufuneka uqaphele ngakumbi, iimfuno zeshishini ngokubanzi zomxholo we-alumina yeglasi ye-photovoltaic kwi-0.95-1.05% okanye ngaphezulu, zinokufumana ukusebenza okuhle kokusika kunye neemfuno zamandla. Ngenxa yokuba i-aluminium hydroxide kulula ukuyinyibilikisa kune-alumina, kwaye inokuvelisa iimolekyuli zamanzi ukuze zikhuphe, ziphucule ukucaciswa, ngoko uninzi lwefektri lukhetha i-aluminium hydroxide njengezinto ezikrwada zokwazisa ukwakheka kwe-alumina. Nangona kunjalo, izifundo zakutshanje zibonise ukuba umgubo we-alumina ocoliweyo ungasetyenziswa kwiglasi ye-photovoltaic ngaphandle kokuchaphazela umgangatho weglasi. Izinto ezikrwada zisebenzisa iimpawu zobukhulu obuncinci besuntswana kunye namandla amakhulu kunomphezulu. Umgaqo wokukhetha wesityalo se-aluminium hydroxide:
5.1 Umxholo we-aluminium oxide kufuneka ube phezulu, i-aluminium hydroxide kufuneka ibe phezulu
5.2 Imfuneko ephantsi yomxholo we-Fe2O3
5.3 Akukho ngcoliseko kwaye akukho kugaywa kweekeyiki.
