kayan aikin ƙarfe na photovoltaic (gilashin PV)

Manyan kayan da ake amfani da su wajen yin gilashin photovoltaic sune: yashi silica, ash na soda, dolomite, dutse mai laushi, aluminum hydroxide, mirabilite, sodium nitrate, sodium pyroantimonate, da kuma wasu gilashin da aka sake yin amfani da su. Saboda buƙatun musamman na watsa haske na gilashin photovoltaic, gabaɗaya ana buƙatar cewa yawan ƙarfe na kowane abu ya yi ƙasa, kuma kayan da ake amfani da su ba su da ƙarfe sosai, domin samun watsa haske mai yawa.

Idan akwai wurin ajiya mai kama da juna, ana iya sassauta tsarin sarrafa ruwa da sarrafa shi yadda ya kamata don biyan buƙatun ciyarwa a cikin wurin ajiya mai kama da juna.

B. Rarraba ƙwayoyin cuta

Dangane da rarraba girman barbashi, wasu rubuce-rubuce sun nuna cewa ana iya rage ma'aunin foda mai kyau zuwa kashi 15% daidai, amma ya kamata a yi la'akari da nau'in murhun. Idan murhun iska ne, ana iya sassauta shi yadda ya kamata, yayin da idan murhun iska ne, bai kamata a sassauta shi ba, don guje wa lahani na ƙurar da ke toshe layin da kuma tashi da ke haifar da lahani na fari. Wurin narkewar yashi na silica shine > 1800℃. Idan akwai manyan barbashi, yanayin rashin narkewa na iya faruwa (ya danganta da adadin jan hankali da kuma yawan narkewar murhun).

A halin yanzu, manyan hanyoyin samun yashi na silica sune: yankin Fengyang, lardin Anhui, Wenchang, lardin Hainan, Hepu, Beihai, Zhanjiang, da yankin Heyuan. A ƙasashen waje, a halin yanzu akwai yashi na Indonesia, Malaysia, Vietnam da Ostiraliya. A cikin fengyang da ingancin ma'adinan heyuan na vein quartz, a matsayin lokutan ƙarshe na kaolin, an sake murƙushe yashi (misali, hepu, yashi na zhanjiang), kuma yashi na teku ne (galibi yana ɗauke da titanium dioxide ba tare da cirewa ko ragewa ba, murhun yana da wasu zaizayar ƙasa, kuma ragowar titanium dioxide a cikin gilashi na iya haifar da gilashin watsa haske na UV).

2. Soda soda, masana'antun gilashi gabaɗaya suna zaɓar babban soda soda, babban sinadarin sodium carbonate, suna taka rawa wajen haɗa shi, girmansa da yashi silica cikin dangantaka, buƙatun masana'antu na ƙa'idodin ingancin soda soda da ƙa'idodin zaɓi sune kamar haka:

2.1 Babban abun ciki na Na2CO3

2.2 Ƙarancin abun ciki na NaCl da Fe2O3

2.3 Girman barbashi mai dacewa kuma babu gurɓatawa da cake.

5. Aluminum hydroxide, galibi yana samar da sassan alumina, ƙarfin gilashin don haɓaka rawar, amma yawan alumina na iya haifar da narkewar bayani game da mummunan yanayi, yana buƙatar a yi taka tsantsan, buƙatun masana'antu na gabaɗaya na abun ciki na alumina na gilashin photovoltaic a cikin 0.95-1.05% ko makamancin haka, na iya samun kyakkyawan aikin yankewa da buƙatun ƙarfi. Saboda aluminum hydroxide yana da sauƙin narkewa fiye da alumina, kuma yana iya samar da ƙwayoyin ruwa don fitarwa, haɓaka haske, don haka yawancin masana'antar shine zaɓin aluminum hydroxide azaman kayan da aka samar don gabatar da abun ciki na alumina. Duk da haka, binciken da aka yi kwanan nan ya nuna cewa har yanzu ana iya amfani da foda alumina na ultrafine akan gilashin photovoltaic ba tare da shafar ingancin gilashin ba. Ana amfani da kayan da aka samar ta amfani da halayen ƙaramin girman barbashi kuma ya fi ƙarfin saman. Ka'idar zaɓi na shukar aluminum hydroxide:

5.1 Ya kamata sinadarin aluminum oxide ya kasance mai yawa, kuma aluminum hydroxide ya kamata ya kasance mai yawa
