Izinto eziyinhloko zokusetshenziswa kwengilazi ye-photovoltaic yilezi: isihlabathi se-silica, umlotha we-soda, i-dolomite, i-limestone, i-aluminium hydroxide, i-mirabilite, i-sodium nitrate, i-sodium pyroantimonate, kanye nengilazi ephukile ephinde yasetshenziswa. Ngenxa yezidingo ezikhethekile zokudluliselwa kokukhanya kwengilazi ye-photovoltaic, ngokuvamile kuyadingeka ukuthi okuqukethwe kwensimbi kwento ngayinye eluhlaza kube kuphansi, kanti into eluhlaza kube yinsimbi ephansi, ukuze kutholakale ukudluliselwa kokukhanya okuphezulu.
1. Isihlabathi se-silica, ingxenye eyinhloko ye-silica, isimiso sokukhetha esijwayelekile sefektri
11 Okuqukethwe okuphezulu kwe-SiO2 kanye nokuqina.
1.2 Okuqukethwe okuphansi kwe-Fe2O3 kanye ne-Al2O3 futhi okuzinzile.
1.3 Azikho izinhlayiya eziphikisayo, njenge-chromite nezinye izinto ezingcolisayo.
1.4 Usayizi wezinhlayiya ofanele, azikho izinhlayiya ezinkulu kanye nempuphu ecolekile eningi kakhulu.
1.5 Umswakama ozinzile.
Izidingo ezithile zenkomba
A. Ukwakheka kwamakhemikhali:
| Okuqukethwe | I-SiO2 | I-Al2O3 | I-Fe2O3 | I-LOI | Umswakama |
| % | ≥99.3±(0.4) | ≤0.3±(0.1) | ≤0.008 | ≤0.15 | ≤5.0 |
Uma kukhona indawo yokugcina amanzi ehlanganisa ukulingana, ukulawula amanzi nokulawula kungakhululeka ngokufanele ukuze kuhlangatshezwane nezidingo zokufaka amanzi endaweni yokugcina amanzi ehlanganisa ukulingana.
B. Ukusatshalaliswa kwezinhlayiya
| mm | 1.0 | 0.71 | 0.50 | 0.125 | -0.125 |
| % | Nil | ≤Akukho | ≤5.0 | ≥90.0 | ≤10.0 |
Ngokuphathelene nokusatshalaliswa kobukhulu bezinhlayiya, ezinye izincwadi zibonisa ukuthi indinganiso yempuphu ecolekile ingakhululeka ngokufanele ifike ku-15%, kodwa uhlobo lwe-oven kufanele lucatshangelwe. Uma kuyi-oven ephefumula umoya-mpilo kuphela, ingakhululeka ngokufanele, kanti uma kuyi-oven yomoya, akufanele ikhululeke, ukuze kugwenywe amaphutha empuphu ecolekile evala i-lattice bese indizela kude okubangela amaphutha amhlophe. Indawo yokuncibilika kwesihlabathi se-silica ingu-> 1800℃. Uma kunezinhlayiya ezinkulu, isimo sokungabikho kokuncibilika singase senzeke (kuye ngokuthi inani lokudonsa kanye nezinga lokuncibilika kwe-oven).
Njengamanje, imithombo eyinhloko yesihlabathi se-silica yilezi: indawo yaseFengyang, iSifundazwe sase-Anhui, iWenchang, iSifundazwe saseHainan, iHepu, iBeihai, iZhanjiang, kanye nendawo yaseHeyuan. Kwamanye amazwe, okwamanje kunesihlabathi sase-Indonesia, saseMalaysia, saseVietnam kanye nesase-Australia. E-fengyang nase-heyuan vein quartz ore ikhwalithi njengezikhathi zokugcina ze-kaolin elutriation eyenziwe nge-sand gravel echotshozwa futhi (isb., i-hepu, isihlabathi saseZhanjiang), futhi isihlabathi solwandle (ikakhulukazi siqukethe i-titanium dioxide engasusi noma inciphise, isitofu sinokuguguleka okuthile, futhi izinsalela ze-titanium dioxide engilazini zingaholela ekudlulisweni kwengilazi yokukhanya kwe-UV phansi).
2. I-soda soda, izimboni zeglasi ngokuvamile zikhetha i-soda esindayo, ingxenye eyinhloko ye-sodium carbonate, zidlala indima ekuhlanganiseni, ubumbumbulu bayo kanye nesihlabathi se-silica ebuhlotsheni, izidingo ezijwayelekile zemboni zezindinganiso zekhwalithi ye-soda soda kanye nezimiso zokukhetha yilezi ezilandelayo:
2.1 Okuqukethwe okuphezulu kwe-Na2CO3
2.2 Okuqukethwe okuphansi kwe-NaCl kanye ne-Fe2O3
2.3 Usayizi wezinhlayiya ofanele futhi awunazo izinto ezingcolisayo kanye nokugoqwa.
Izidingo ezithile zenkomba
A. Izidingo zesithako:
| Okuqukethwe | I-Na2CO3 | I-NaCl | Ukulahlekelwa | I-Fe2O3 |
| % | ≥99.0 | ≤0.50 | ≤0.50 | 0.0030 |
5. I-aluminium hydroxide, ikakhulukazi enikeza izingxenye ze-alumina, amandla engilazi ukuze ithuthukise indima, kodwa okuqukethwe okuphezulu kwe-alumina kungaholela ekucacisweni kokuncibilika kwesimo esibi, kudingeka uqaphele ukwandisa, izidingo ezijwayelekile zemboni yokuqukethwe kwe-alumina yengilazi ye-photovoltaic ku-0.95-1.05% noma ngaphezulu, kungathola ukusebenza okuhle kokusika nezidingo zamandla. Ngoba i-aluminium hydroxide kulula ukuyincibilikisa kune-alumina, futhi ingakhiqiza ama-molecule amanzi ukuze ikhiphe, ithuthukise ukucaciswa, ngakho-ke iningi lemboni likhetha i-aluminium hydroxide njengezinto zokusetshenziswa ukuze kwethulwe ukwakheka kwe-alumina. Kodwa-ke, izifundo zakamuva zikhombisile ukuthi i-aluminium powder e-ultrafine ingasetshenziswa engilazini ye-photovoltaic ngaphandle kokuthinta ikhwalithi yengilazi. Izinto zokusetshenziswa kusetshenziswa izici ezincane kakhulu futhi ezinkulu kunobuso bamandla. Isimiso sokukhetha isitshalo se-aluminium hydroxide:
5.1 Okuqukethwe kwe-aluminium oxide kufanele kube phezulu, i-aluminium hydroxide kufanele ibe phezulu
5.2 Isidingo sokuqukethwe okuphansi kwe-Fe2O3
5.3 Akukho ukungcola futhi akukho ukugaywa kwamakhekhe.
