Okwangoku, ngenxa yophuhliso olunamandla lweshishini le-solar photovoltaic, ukusebenza kunye nokuzinza kwezixhobo zokugrumba ngelanga kudlala indima ebalulekileyo ekuvelisweni kweeseli ze-photovoltaic ezisebenzayo kakhulu. Isiseko segranite, esinokuxhathisa ukugrumba okubalaseleyo kunye neempawu zokulwa nokwaluphala, siye saba yinxalenye ebalulekileyo yezixhobo zokugrumba ngelanga.
Melana nokugqwala kwe-asidi enamandla kunye ne-alkali kwaye ukhusele ubumsulwa benkqubo yokugqwala
Ngexesha lenkqubo yokugrumba ngelanga, kusetyenziswa ii-reagents zeekhemikhali ezigrumba kakhulu ezifana ne-hydrofluoric acid kunye ne-nitric acid, ezinefuthe elikhulu lokugrumba kwiindawo zezixhobo. Iziseko zesinyithi eziqhelekileyo okanye ezinye izinto zisengozini yokugrumba nokugrumba emva kokudibana ixesha elide nezinto ezinjalo zeekhemikhali. Oku akungcolisi nje isisombululo sokugrumba kodwa kukwachaphazela ukuchaneka kunye nokuzinza kwezixhobo.
I-granite yenziwe kakhulu ziiminerali ezifana ne-quartz kunye ne-feldspar, kwaye iipropati zayo zeekhemikhali zizinzile kakhulu. Xa ijongene nemeko enamandla ye-asidi kunye ne-alkali kwinkqubo yokugrumba, isiseko se-granite sinokumelana ngempumelelo nokugrumba. Ngokwedatha evela kumaziko ovavanyo lobuchwephesha, xa isiseko se-granite sintywiliselwa kwisisombululo se-hydrofluoric acid esingama-20% iiyure ezingama-24, ubukhulu bomphezulu wokugrumba buyi-0.001mm kuphela, nto leyo ephantse ingabi namsebenzi. Olu xhathiso lubalaseleyo lokugrumba luqinisekisa ukuba ubunyulu besisombululo sokugrumba abuyi kuchaphazeleka kukugrumba kwesiseko ngexesha lokusetyenziswa kwexesha elide kwezixhobo zokugrumba, ngaloo ndlela kuqinisekisa uzinzo kunye nokuhambelana kwenkqubo yokugrumba kunye nokuphucula izinga lemveliso yeeseli ze-photovoltaic.
Isebenza kakuhle kakhulu ekulweni nokwaluphala kwaye inokwandisa ubomi benkonzo yezixhobo
Ngexesha lenkqubo yokuvelisa izixhobo zokugrumba ngelanga, ayimelani nje kuphela nokuguguleka kweekhemikhali, kodwa ikwafumana utshintsho rhoqo kubushushu kunye nokungcangcazela koomatshini. Izixhobo eziqhelekileyo, phantsi kwesiphumo sexesha elide sokwanda kobushushu kunye nokuxinana kunye noxinzelelo loomatshini, zichaphazeleka ziingxaki ezifana nokwaluphala kunye nokuguquka, okukhokelela ekwehleni kokuchaneka kwezixhobo kunye nesidingo sokutshintsha izinto okanye umatshini wonke kwangaphambili.
I-Granite inesakhiwo sangaphakathi esixineneyo nesifanayo, kwaye iikristale zayo zeminerali zidityaniswe ngokusondeleyo. Phantsi kweemeko eziqhelekileyo zokusetyenziswa, nokuba emva kwamashumi eminyaka aliqela, iimpawu zomzimba zesiseko se-granite aziyi kutshintsha kakhulu. Ukusebenza kwayo okuchasene nokwaluphala kwenza izixhobo zokugcaba ngelanga zigcine ukuchaneka okuphezulu kunye nokuzinza ixesha elide. Umzekelo, ishishini elithile le-photovoltaic lisebenzise izixhobo zokugcaba ezixhotyiswe ngesiseko se-granite. Emva kokusebenza ngokuqhubekayo iminyaka eli-15, ukuchaneka kokubekwa kwezixhobo kusenokugcinwa ngaphakathi kwe-±0.05mm, okuphantse kufane nokuchaneka xa izixhobo zaqala ukusetyenziswa. Xa kuthelekiswa nezixhobo ezisebenzisa iziseko zezinto eziqhelekileyo, umjikelo wokugcinwa wolulwa amaxesha ama-2 ukuya kwama-3, ubomi benkonzo yezixhobo buphucuke kakhulu, kwaye iindleko ezininzi zokutshintshwa kwezixhobo kunye nokugcinwa kwazo zigcinwa kumashishini.
Isiqinisekiso sokusebenza esizinzileyo sinceda ishishini le-photovoltaic ukunciphisa iindleko kunye nokwandisa ukusebenza kakuhle
Ukumelana nokugqwala kunye neempawu zokulwa nokuguga zesiseko segranite zibonelela ngeziqinisekiso zokusebenza ezizinzileyo nezithembekileyo kwizixhobo zokugqwala ngelanga. Ukusebenza kwezixhobo ezizinzileyo kuthetha ukusebenza kakuhle kwemveliso kunye nesantya esiphantsi sokulahlwa. Thatha umgca wemveliso onomthamo wonyaka we-500MW weeseli ze-photovoltaic njengomzekelo. Izixhobo zokugqwala ezinesiseko segranite zinokunciphisa ixesha lokungasebenzi kokugcinwa okubangelwa kukugqwala kwezixhobo kunye nokuguga malunga neeyure ezili-100 ngonyaka, kwaye zonyuse ixabiso leemodyuli zeeseli ze-photovoltaic eziveliswa malunga ne-2 yezigidi zeeyuan. Okwangoku, ngenxa yenkqubo yokugqwala ezinzileyo ngakumbi, izinga lemveliso lenyuke ngamanqaku eepesenti ezi-2 ukuya kwezi-3, nto leyo enciphisa ngakumbi iindleko zemveliso.
Phantsi kwemvelaphi yeshishini le-solar photovoltaic elifuna ukulingana kwegridi kunye nokunciphisa iindleko kunye nokuphucula ukusebenza kakuhle, iziseko zegranite, ezineempawu zazo ezintle zokumelana nokugqwala kunye nokulwa nokwaluphala, ziye zaba ngundoqo ekuphuculeni ukusebenza kunye nokunciphisa iindleko zezixhobo zokugcaba ngelanga. Ayiboneleli nje kuphela ngesiqinisekiso esiqinileyo semveliso esemgangathweni ophezulu yeeseli ze-photovoltaic, kodwa ikwanegalelo kuphuhliso oluzinzileyo lweshishini lonke le-photovoltaic.
