galaas koronto-dhaliye (galaas PV) oo ceeriin ah

Alaabta ceeriin ee ugu muhiimsan ee galaaska photovoltaic waa: ciid silica ah, dambas soodhaha ah, dolomite, dhagaxa nuuradda ah, aluminium hydroxide, mirabilite, sodium nitrate, sodium pyroantimonate, iyo galaas dib loo warshadeeyay oo jabay. Iyada oo ay ugu wacan tahay shuruudaha gaarka ah ee gudbinta iftiinka ee galaaska photovoltaic, guud ahaan waxaa loo baahan yahay in birta ku jirta walax kasta oo cayriin ah ay yar tahay, walaxda cayriin-na ay tahay bir yar, si loo helo gudbinta iftiinka sare.

1. Ciidda silikoonka, qaybta ugu weyn ee silikoonka, mabda'a guud ee xulashada warshadda

11 Heerka sare ee SiO2 iyo xasilloonida.

1.2 Heer hoose oo Fe2O3 iyo Al2O3 ah iyo mid deggan.

1.3 Ma jiraan wax walxo ah oo aan la isku halleyn karin, sida chromite iyo waxyaabo kale oo wasakhaysan.

1.4 Cabbirka walxaha ku habboon, ma jiraan walxo waaweyn iyo budo aad u fiican.

1.5 Qoyaan deggan.

Shuruudaha tusmada gaarka ah

A. Halabuurka kiimikada:

Haddii ay jirto xarun kaydin oo isku mid ah, xakamaynta iyo xakamaynta biyaha si habboon ayaa loo dejin karaa si loo daboolo shuruudaha quudinta kaydinta isku midka ah.

B. Qaybinta walxaha

Marka la eego qaybinta cabbirka walxaha, qaar ka mid ah qoraallada ayaa muujinaya in heerka budada khafiifka ah si habboon loo dhimi karo ilaa 15%, laakiin nooca foornada waa in la tixgeliyaa. Haddii ay tahay foorno oksijiin ah, si habboon ayaa loo dejin karaa, halka haddii ay tahay foorno hawo ah, waa in aan la dejin, si looga fogaado cilladaha budada khafiifka ah ee xirta shabagga oo duulaya taasoo keenta cillado cad. Barta dhalaalka ee ciidda silica waa > 1800℃. Haddii ay jiraan walxo waaweyn, xaaladda dhalaal la'aan ayaa dhici karta (iyadoo ku xiran xaddiga jiidista iyo heerka dhalaalka ee foornada).

Waqtigan xaadirka ah, ilaha ugu muhiimsan ee ciidda silica waa: aagga Fengyang, Gobolka Anhui, Wenchang, Gobolka Hainan, Hepu, Beihai, Zhanjiang, iyo aagga Heyuan. Dibadda, waxaa hadda jira ciid Indonesian, Malaysian, Vietnamese iyo Australian ah. Tayada macdanta fengyang iyo heyuan ee xididka quartz ayaa ah waqtigii ugu dambeeyay ee kaolin loo sameeyay burburinta quruurux ciid mar kale (tusaale ahaan, hepu, ciid zhanjiang), mar kale waa ciidda badda (inta badan waxaa ku jira titanium dioxide oo aan laga saarin ama la dhimin, foornada waxay leedahay nabaad-guur gaar ah, haraaga titanium dioxide ee galaaska waxay horseedi kartaa galaaska gudbinta iftiinka UV).

2. Soodhaha Soodhaha, warshadaha galaaska guud ahaan waxay doortaan soodhaha soodhaha culus, qaybta ugu weyn ee soodhaha kaarboonat, waxay door ka ciyaaraan isku-darka, dhumucdeeda iyo ciidda silica ee xiriirka, shuruudaha guud ee warshadda ee heerarka tayada soodhaha soodhaha iyo mabaadi'da xulashada waa sida soo socota:

2.1 Na2CO3 oo sarreeya

2.2 NaCl iyo Fe2O3 oo hooseeya

2.3 Cabbirka walxaha ku habboon iyo ka xor ah wasakhda iyo dubista.

Shuruudaha tusmada gaarka ah

A. Shuruudaha Maaddada:

5. Aluminium hydroxide, oo inta badan bixisa qaybaha alumina, xoogga galaaska si loo xoojiyo doorka, laakiin maaddada sare ee alumina waxay horseedi kartaa dhalaalidda caddaynta xaaladda liidata, waa in taxaddar la muujiyaa, shuruudaha guud ee warshadaha ee maaddada alumina galaaska photovoltaic ee 0.95-1.05% ama wax la mid ah, waxay heli karaan waxqabad wanaagsan iyo shuruudaha xoogga. Sababtoo ah aluminium hydroxide way ka fududahay in la dhalaaliyo marka loo eego alumina, waxayna soo saari kartaa molecules biyo ah si loo sii daayo, loo xoojiyo caddeynta, sidaa darteed inta badan warshadda waa doorashada aluminium hydroxide oo ah walxaha ceeriin ah si loo soo bandhigo halabuurka alumina. Si kastaba ha ahaatee, daraasado dhowaan la sameeyay ayaa muujiyay in budada alumina ultrafine wali loo isticmaali karo galaaska photovoltaic iyada oo aan saameyn ku yeelan tayada galaaska. Maaddada ceeriin waxaa loo isticmaalaa sifooyinka cabbirka walxaha yar yar iyo ka weyn tamarta dusha sare. Mabda'a xulashada warshadda aluminium hydroxide:

5.1 Ka kooban oksaydhka aluminiumku waa inuu sarreeyaa, hydroxide-ka aluminiumku waa inuu sarreeyaa

5.2 Shuruudaha Fe2O3 ee hooseeya

5.3 Ma jiraan wax wasakh ah iyo wax la isku qurxiyo.
