Cov khoom siv tseem ceeb ntawm cov iav photovoltaic yog: xuab zeb silica, soda tshauv, dolomite, limestone, aluminium hydroxide, mirabilite, sodium nitrate, sodium pyroantimonate, thiab qee cov iav tawg rov ua dua tshiab. Vim yog qhov tshwj xeeb xav tau rau lub teeb transmittance ntawm cov iav photovoltaic, feem ntau nws yuav tsum tau tias cov ntsiab lus hlau ntawm txhua yam khoom siv raw yog qis, thiab cov khoom siv raw yog tsawg hlau, txhawm rau kom tau txais lub teeb transmittance siab.
1. Xuab zeb silica, lub ntsiab lus tseem ceeb ntawm silica, lub hauv paus ntsiab lus xaiv dav dav ntawm lub Hoobkas
11 Cov ntsiab lus SiO2 siab thiab ruaj khov.
1.2 Cov ntsiab lus Fe2O3 thiab Al2O3 tsawg thiab ruaj khov.
1.3 Tsis muaj cov khoom me me uas tsis yooj yim tawg, xws li chromite thiab lwm yam kuab paug.
1.4 Qhov loj me ntawm cov khoom me me, tsis muaj cov khoom loj thiab hmoov zoo ntau dhau.
1.5 Cov dej noo ruaj khov.
Cov kev cai tshwj xeeb ntawm cov ntsuas
A. Cov tshuaj lom neeg muaj pes tsawg leeg:
| Cov Ntsiab Lus | SiO2 | Al2O3 | Fe2O3 | LOI | Cov dej noo |
| % | ≥99.3 ± (0.4) | ≤0.3 ± (0.1) | ≤0.008 | ≤0.15 | ≤5.0 |
Yog tias muaj qhov chaw cia khoom homogenizing, qhov kev tswj thiab kev tswj dej tuaj yeem ua kom yooj yim kom tau raws li qhov yuav tsum tau ua ntawm kev pub rau hauv qhov chaw cia khoom homogenizing.
B. Kev faib tawm ntawm cov khoom me me
| mm | 1.0 | 0.71 | 0.50 | 0.125 | -0.125 |
| % | Tsis muaj dab tsi | ≤ Tsis muaj | ≤5.0 | ≥90.0 | ≤10.0 |
Hais txog qhov faib tawm ntawm cov khoom me me, qee cov ntaub ntawv qhia tias tus qauv hmoov zoo tuaj yeem so kom txaus rau 15%, tab sis hom qhov cub yuav tsum tau xav txog. Yog tias nws yog lub qhov cub uas muaj oxygen tag nrho, nws tuaj yeem so kom txaus, thaum yog tias nws yog lub qhov cub cua, nws yuav tsum tsis txhob so, kom tsis txhob muaj qhov tsis zoo ntawm cov hmoov zoo txhaws lub lattice thiab ya mus ua rau muaj qhov tsis zoo dawb. Lub ntsiab lus yaj ntawm cov xuab zeb silica yog> 1800 ℃. Yog tias muaj cov khoom loj dua, qhov xwm txheej ntawm tsis yaj yuav tshwm sim (nyob ntawm qhov traction thiab qhov nrawm yaj ntawm lub qhov cub).
Tam sim no, cov chaw tseem ceeb ntawm cov xuab zeb silica yog: Fengyang cheeb tsam, Anhui xeev, Wenchang, Hainan xeev, Hepu, Beihai, Zhanjiang, thiab Heyuan cheeb tsam. Txawv teb chaws, tam sim no muaj Indonesian, Malaysian, Nyab Laj thiab Australian xuab zeb. Hauv fengyang thiab heyuan vein quartz ore zoo li lub sijhawm kawg rau kaolin elutriation ua xuab zeb gravel crushing dua (piv txwv li, hepu, zhanjiang xuab zeb), dua yog xuab zeb hiav txwv (feem ntau muaj titanium dioxide tsis tshem tawm lossis txo, lub kiln muaj qee qhov erosion, thiab titanium dioxide residues hauv iav tuaj yeem ua rau lub teeb uv transmittance iav poob).
2. Cov dej qab zib, cov chaw tsim khoom iav feem ntau xaiv cov dej qab zib hnyav, cov khoom tseem ceeb ntawm sodium carbonate, ua lub luag haujlwm hauv kev sib xyaw, nws cov granularity thiab silica xuab zeb mus rau hauv kev sib raug zoo, cov kev cai dav dav ntawm cov dej qab zib soda cov qauv zoo thiab cov ntsiab cai xaiv yog raws li nram no:
2.1 Cov ntsiab lus Na2CO3 siab
2.2 Cov ntsiab lus qis ntawm NaCl thiab Fe2O3
2.3 Qhov loj me ntawm cov khoom me me thiab tsis muaj cov kuab paug thiab cov khoom sib xyaw.
Cov kev cai tshwj xeeb ntawm cov ntsuas
A. Cov khoom xyaw uas yuav tsum tau muaj:
| Cov Ntsiab Lus | Na2CO3 | NaCl | Kev poob | Fe2O3 |
| % | ≥99.0 | ≤0.50 | ≤0.50 | 0.0030 |
5. Aluminium hydroxide, feem ntau muab cov khoom alumina, lub zog ntawm lub iav los txhim kho lub luag haujlwm, tab sis cov ntsiab lus alumina siab yuav ua rau yaj qhov tsis zoo, yuav tsum tau ceev faj ntxiv, cov kev xav tau dav dav ntawm cov iav photovoltaic alumina cov ntsiab lus hauv 0.95-1.05% lossis li ntawd, tuaj yeem tau txais kev ua tau zoo thiab lub zog xav tau. Vim tias aluminium hydroxide yooj yim dua rau yaj dua li alumina, thiab tuaj yeem tsim cov dej molecules kom tso tawm, txhim kho kev meej, yog li feem ntau ntawm lub Hoobkas yog kev xaiv ntawm aluminium hydroxide ua cov khoom siv raw los qhia cov khoom alumina. Txawm li cas los xij, cov kev tshawb fawb tsis ntev los no tau qhia tias ultrafine alumina hmoov tseem tuaj yeem siv rau ntawm iav photovoltaic yam tsis cuam tshuam rau qhov zoo ntawm lub iav. Cov khoom siv raw yog ua los ntawm kev siv cov yam ntxwv ntawm cov khoom me me thiab loj dua lub zog ntawm qhov chaw. Txoj cai xaiv ntawm aluminium hydroxide cog:
5.1 Cov ntsiab lus ntawm txhuas oxide yuav tsum siab, txhuas hydroxide yuav tsum siab
5.2 Cov ntsiab lus Fe2O3 qis dua
5.3 Tsis muaj kuab paug thiab tsis muaj caking.
