galasi la photovoltaic (galasi la PV) zopangira

Zipangizo zazikulu zopangira galasi la photovoltaic ndi izi: mchenga wa silika, soda ash, dolomite, limestone, aluminium hydroxide, mirabilite, sodium nitrate, sodium pyroantimonate, ndi magalasi ena osweka omwe amabwezeretsedwanso. Chifukwa cha zofunikira zapadera zoperekera kuwala kwa galasi la photovoltaic, nthawi zambiri pamafunika kuti chitsulo chilichonse chikhale chochepa, ndipo chipangizocho chikhale chochepa, kuti chipereke kuwala kwambiri.

1. Mchenga wa silika, gawo lalikulu la silika, mfundo yosankha fakitale yonse

11 Kuchuluka kwa SiO2 ndi kukhazikika.

1.2 Kuchuluka kwa Fe2O3 ndi Al2O3 kochepa komanso kokhazikika.

1.3 Palibe tinthu tomwe timakana zinthu monga chromite ndi zinthu zina zoipitsa.

1.4 Kukula koyenera kwa tinthu tating'onoting'ono, palibe tinthu tating'ono ...

1.5 Chinyezi chokhazikika.

Zofunikira zenizeni za index

A. Kapangidwe ka mankhwala:

Ngati pali malo osungira madzi ogwirizana, njira yowongolera madzi ndi kulamulira madzi ikhoza kuchepetsedwa moyenera kuti ikwaniritse zofunikira pakudyetsa madzi mu malo osungira madzi ogwirizana.

B. Kugawa tinthu tating'onoting'ono

Ponena za kukula kwa tinthu tating'onoting'ono, mabuku ena amasonyeza kuti muyezo wa ufa wosalala ukhoza kuchepetsedwa kufika pa 15%, koma mtundu wa uvuni uyenera kuganiziridwa. Ngati ndi uvuni wopangidwa ndi mpweya wokwanira, ukhoza kuchepetsedwa bwino, pomwe ngati ndi uvuni wopangidwa ndi mpweya, suyenera kuchepetsedwa, kuti tipewe zolakwika za ufa wosalala zomwe zingatseke latisi ndikuuluka zomwe zimayambitsa zolakwika zoyera. Malo osungunuka a mchenga wa silika ndi > 1800℃. Ngati pali tinthu tating'onoting'ono tating'onoting'ono, vuto la kusungunuka silingachitike (kutengera kuchuluka kwa mphamvu yogwirira ntchito ndi kuchuluka kwa kusungunuka kwa uvuni).

Pakadali pano, magwero akuluakulu a mchenga wa silika ndi awa: dera la Fengyang, Chigawo cha Anhui, Wenchang, Chigawo cha Hainan, Hepu, Beihai, Zhanjiang, ndi dera la Heyuan. Kunja, pakadali pano pali mchenga wa ku Indonesia, Malaysia, Vietnamese ndi Australia. Mu fengyang ndi heyuan vein quartz ore quality monga nthawi yomaliza ya kaolin elutriation anapanga mchenga kuphwanya kachiwiri (monga hepu, mchenga wa zhanjiang), kachiwiri ndi mchenga wa m'nyanja (makamaka muli titanium dioxide osachotsa kapena kuchepetsa, uvuni uli ndi kukokoloka kwina, ndipo zotsalira za titanium dioxide mugalasi zimatha kubweretsa kuwala kwa UV pansi pa galasi).

2. Mafakitale agalasi nthawi zambiri amasankha soda yolemera, yomwe ndi gawo lalikulu la sodium carbonate, yomwe imagwira ntchito pophatikizana, granularity yake ndi mchenga wa silika kuti ugwirizane, zofunikira zonse za soda ndi mfundo zosankhidwa ndi mafakitale ndi izi:

2.1 Zambiri za Na2CO3

2.2 Kuchepa kwa NaCl ndi Fe2O3

2.3 Kukula koyenera kwa tinthu tating'onoting'ono komanso kopanda zodetsa kapena zophimba.

Zofunikira zenizeni za index

A. Zofunikira pa chinthu:

5. Aluminiyamu hydroxide, makamaka imapereka zinthu za alumina, mphamvu ya galasi kuti iwonjezere ntchito, koma kuchuluka kwa alumina kungayambitse kusungunuka kwa zinthu zosauka, ndikofunikira kusamala, chifukwa chake ndikofunikira kusamala kuti kuchuluka kwa alumina mu galasi la photovoltaic kuli pakati pa 0.95-1.05% kapena kuposerapo, zomwe zimapangitsa kuti magwiridwe antchito abwino komanso mphamvu zikhale bwino. Chifukwa aluminiyamu hydroxide ndi yosavuta kusungunuka kuposa alumina, imatha kutulutsa mamolekyulu amadzi, ndikuwonjezera kumveka bwino, chifukwa chake ambiri mwa opanga amasankha aluminiyamu hydroxide ngati zopangira kuti apereke kapangidwe ka alumina. Komabe, kafukufuku waposachedwa wasonyeza kuti ufa wa alumina wa ultrafine ukhoza kugwiritsidwabe ntchito pagalasi la photovoltaic popanda kukhudza mtundu wa galasi. Zinthu zopangira zimagwiritsidwa ntchito ndi tinthu tating'onoting'ono komanso tokulirapo kuposa mphamvu ya pamwamba. Mfundo yosankha chomera cha aluminiyamu hydroxide:

5.1 Kuchuluka kwa aluminiyamu oxide kuyenera kukhala kochuluka, aluminiyamu hydroxide iyenera kukhala yochuluka

5.2 Zofunikira zochepa za Fe2O3

5.3 Palibe kuipitsa chilengedwe komanso palibe kuyika zinthu m'mabokosi.
