Ko te Quartz te waahanga kohuke nui o te maha o nga toka penei i te granite me te gneiss, a he tino kohuke ahumahi. Ko nga rauemi quartz e whakamahia nuitia ana i roto i te mara photovoltaic, a koinei tetahi o nga rawa matua matua mo te ahumahi photovoltaic.
Raw Material for Industrial Silicon: Silica Ore
Ko te silica ore te mea tino nui rawa atu mo te whakarewanga o te silicon ahumahi, a ko te ingoa nui hoki o nga kohuke e pa ana ki te kiripaka penei i te vein quartz, quartzite me te kirikiri kirikiri. Ko te silicon ahumahi, e mohiotia ana ko te silicon metal, he mea hanga ki te silica ore (ko te waahanga matua ko te silicon dioxide), te waro, te waro me te petroleum coke me etahi atu reductants waro, i hangaia e te tauhohenga whakaheke teitei, ka taea te whakarite silicon ahumahi hei polysilicon i muri mai. purenga atu.
Hikohiko Photovoltaic, polysilicon kōeke solar, ko te rauemi mata matua o te pūnaha whakaputa hiko photovoltaic, ko te rauemi mata whakarunga o te mekameka ahumahi photovoltaic, he totoka hina-pango ki te umeraa konganuku, he ira whakarewa tiketike, pakeke, brittleness, matū kore mahi i te pāmahana rūma me ētahi atu āhuatanga, me ngā āhuatanga semiconducting, he rauemi semiconductor tino nui, e mohiotia ana ko te mekameka ahumahi photovoltaic o te "koura pango! ". Ko te hangarau hanga polysilicon auraki o naianei kei te whakapai ake i te tikanga Siemens me te tikanga mo te moenga waiu silane, te ahua hua mo te hiraka rakau me te silicon granular.
Ka taea te whakamahi i te Polysilicon hei rauemi mata mo te tohi i te silicon monocrystalline. Karekau he tikanga whakakoero rohe whakatara whakarewa me te tikanga toia totika. Ko te tikanga rewa rohe whakarewa-kore-kore e pa ana ki te whakamahi i nga coils auau-nui i roto i te ruma oumu korehau, ko te karaihe kakano karaihe kotahi me nga rakau polysilicon e hono ana ki te rohe rewa, a, i te mutunga ka whakaputa i te tino parakore, iti-diameter silicon monocrystalline.
Ko te tikanga tohanga tika ko te tikanga Cheklausky, ko te tikanga me horoi i te kirikiri polycrystalline raw i te tuatahi ki te tango i ona poke o te mata, katahi ka mau te karaihe uri ki roto i te raima toi, i muri i te whakaurunga o te karaihe, hoatu te te pakihiwi, te tipu isodiametric, te kati me etahi atu tukanga, me te mutunga ka whakaputa i te silicon monocrystalline.
Raw Material of Quartz Crucible: High Purity Sand Quartz
Ko te parapara kiripaka he momo ipu, he mea hanga mai i te kirikiri kiripaka parakore na roto i te hanga pokepokea me te hanga i te pāmahana teitei ma te whakamahi i te tikanga pewa hiko. Ko te ahuatanga o te teitei o te pāmahana, te wa roa o te ratonga, te maatanga teitei, me era atu. Ko te nuinga o te waa ka whakamahia hei taputapu awhina mo te hikohiko me te hiko o te ra e toia ana nga rakau silicon monocrystalline.
I roto i te hanga silicon monocrystalline, ko te quartz crucible he wa kotahi te whakamahi o te silicon whakarewa me te tipu karaihe o nga rauemi matua, ko te utu hanga o te silicon monocrystalline me te kounga o te hua hua ka whai paanga tika.
Ko te parapara kiripaka e whakamahia ana mo te hanga silicon monocrystalline i Haina te nuinga o te waa ka tango i nga papa-rua-papa-toru-toru ranei, a ko te ma o te kirikiri kiripaka ka pa tika ki te kounga o nga rakau silicon mo te toia karaihe. Ko te iti o te ma o te kirikiri kiripaka, ka kaha ake te whakaputa i nga waahi pango me nga mirumiru i roto i te tukanga whakarewa wera nui. Ka whakamahia hei onepu paparanga o roto, he roa te wa i roto i te taiao pāmahana teitei ka hanga te kiripaka i roto i te pakitara o roto he mirumiru hau ka tukuna e te wera, na reira ka pa ki te pumau me te reeti angitu o te hanga angiangi angiangi monocrystalline. Na reira, ko te kirikiri o roto e hiahia ana kia nui ake te ma o te kirikiri kiripaka me te utu nui ake. Ko te kiripaka kiripaka a Haina me te onepu o roto me etahi atu hua o te quartz high-end me kawemai mai i te United States, Norway, me etahi atu, ko nga whakaritenga o te kounga o te quartz crucible he iti iho i roto i te onepu o waho, te rauemi mata o te me kawe mai ano ana kohu mai i Inia me etahi atu whenua hei whakaoti i te raruraru. I te nuinga o te korero, ko nga rauemi mata o te onepu o roto mo te kiripaka kiripaka ko te kiripaka pegmatite granite mai i te rohe o Spruce Pine o North Carolina, USA, e tohuhia ana e w(SiO2)≥99.998% (4N8) me te kounga pumau. Ko te rauemi mata mo te onepu waenga ko te vein quartz A grade ore i kawemai mai i Inia me etahi atu whenua, e tohuhia ana e w(SiO2) ≥99.998% (4N8). Ko te rauemi mata matua o te onepu o waho ko te kounga me te pumau o Inia me etahi atu whenua i kawemai he iti te iti o te quartz vein quartz A-grade, tata ranei ki te A-grade B-grade ore, e tohuhia ana e w(SiO2)≥99.995% (4N5) . Ko te kounga o te hua kiripaka kowhatu e pa ana ki te kounga me te utu o te silicon monocrystalline toia tika, i te mea ko te whakahou ake o te mahi toi karaihe ka nui ake nga whakaritenga mo te purea, te ora me te rahi o te quartz crucible, me te whakaihiihi i te hiahia mo te quartz crucible teitei. Ko te kirikiri kiripaka te mea matua mo te hanga quartz crucible, ko tona taumata kounga me te taumata utu e tino whakatau ana i te mahi me te utu o te quartz crucible, na reira, me whakapai ake te kounga o te kirikiri kiripaka parakore teitei mai i te matawai puna kohuke quartz, te tukatuka me etahi atu waahanga, kia pai ake ai te kounga o te quartz crucible ki te whakatutuki i te hiahia i roto i te hanga o te kirikiri monocrystalline tika-whakaahua photovoltaic.
Te Matapihi Matapihi Ataahua: Te kirikiri kiripaka rino iti
Ko te karaihe PV he taputapu nui i roto i te mekameka ahumahi PV me tetahi waahanga e kore e taea te whakakapi i nga waahanga whakangao hiko PV, i te mea ko te kirikiri kiripaka tetahi o nga rawa matua mo te hanga karaihe PV, a ko te kounga o te kirikiri kiripaka he paanga nui ki te te kounga o te karaihe PV. He rereke te karaihe PV mai i te karaehe noa, he mea hanga na roto i te tukatuka hohonu o te karaihe ultra-ma. Ko te karaehe ultra-ma ko te ahua o te karaehe rino iti ultra-marama, e mohiotia ana ko te karaihe rino iti, te karaihe maramara teitei, me te iti o te pahū-whaiaro, te rite o te tae, te whakawhiti marama teitei, te pai o te permeability, te iti o te ultraviolet transmittance, etc . Ko te karaehe he iti ake te nui o te rino. Ko te hanga karaihe Photovoltaic me iti te rino o te kirikiri kiripaka super ma, e 13% o te utu o te karaihe; He iti-kounga tiketike-rino super ma kiripaka kiripaka ore o Haina he āhua onge, kukū i roto i Anhui Fengyang, Guangdong Heyuan, Hunan, Guangxi me Hainan, me ētahi atu, te vai i roto i te ahumahi i roto i tetahi tohu o te monopoly tūturu; ki te kaihautu karaihe photovoltaic o naianei, hei tauira, ko Xinyi photovoltaic me te turanga whakaputa a Follett kei Beihai, Guangxi, Anhui Wuhu me Fengyang, me etahi atu, e tautoko ana i te kirikiri kirikiri kirikiri kounga teitei, ko te turanga whakaputa kei Beihai, Anhui Wuhu me Fengyang. Ko nga turanga whakaputa o Xinyi photovoltaic me Follett e arotahi ana ki Beihai o Guangxi, Wuhu o Anhui Province me Fengyang, me etahi atu, he mea tino pai ki nga maina kirikiri kirikiri kounga teitei, me te kounga o nga rauemi mata he pumau, he iti te utu, he pai ki te whakapai ake i te pumau o nga hua kua oti me te whakaiti i te utu whakaputa.
Ko nga rauemi mata Quartz kei roto i nga momo poke, penei i te Fe, Al, K, Na, Ca, me etahi atu, i roto i te hanga o te karaihe ultra-ma ko nga poke kino rawa atu o nga poke rino, ka taea te noho i te ahua o te ahua kore utu, engari ka taea ano he kiriata angiangi, he whakakapi kurupae, he whakaurunga ranei i roto i te ahua o nga kohuke, e tika ana kia tangohia he raupapa o nga tukanga.
Mo te tango i nga poke rino, me haere i roto i te raupapa o te tinana me te matū tukanga hohonu-tukatuka, kia rite ki te tikanga tango te nuinga wehea ki tikanga tinana (horoi me te māka desliming, scrubbing, wehenga autō, re-pootitanga), matū tikanga (flotation, wairewa waikawa) me tikanga moroiti, me ētahi atu, i roto i te kiripaka rauemi raw tukanga hohonu-tukatuka taea te hāngai i runga i te ahua o te poke rino me te āhua o te noho o te huinga o enei tikanga, i roto i te tikanga ki te kitea he he pai mo te puna o te tukanga tukatuka hohonu o te ore.
Opaniraa
Ko te kirikiri kiripaka he mahi e kore e taea te whakakapi i roto i te ahumahi photovoltaic i roto i te silicon ahumahi, i nga crucibles quartz me te karaihe photovoltaic. Na te tipu o te hiahia o te ao mo te kaha whakahou, te tere o te whanaketanga o te ahumahi photovoltaic me te nui o te pikinga o te kaha whakauru o te photovoltaics, ko tana tono mo te kirikiri kiripaka kua kite i te tipu tere.
