1. He aha te silicon whakarewa?
Ko te silicon whakarewa, e mōhiotia ana ko te silicon ahumahi, he hua o te whakarewanga o te hauhā silicon me te kaiwhakaiti waro i roto i te oumu pewa i raro i te wai. Ko te wāhanga matua o te silicon he nui ake i te 98.5% me te iti iho i te 99.99%, ā, ko ngā paru e toe ana ko te rino, te konumohe, te konupūmā, me ētahi atu.
I Haina, ka wehea te konganuku silicon ki ngā momo rerekē pērā i te 553, 441, 421, 3303, 2202, 1101, me ētahi atu, e wehea ana i runga i te nui o te rino, te konumohe me te konupūmā.
2. Mara tono o te silicon whakarewa
Ko ngā whakamahinga o te silicon whakarewa ko te silicon, te polysilicon me ngā koranu konumohe te nuinga. I te tau 2020, ko te tapeke o te whakamahinga a Haina e tata ana ki te 1.6 miriona tana, ā, ko te ōwehenga whakamahinga e whai ake nei:
He nui ngā whakaritenga mō te silica gel mō te silicon whakarewa, ā, me whiwhi i te taumata matū, e rite ana ki te tauira 421#, ā, whai muri ko te polysilicon, ngā tauira 553# me te 441# e whakamahia whānuitia ana, ā, he iti rawa ngā whakaritenga mō te koranu konumohe.
Heoi, i ngā tau tata nei, kua piki ake te hiahia mō te polysilicon i roto i te silicon waro, ā, kua nui haere tonu tōna ōwehenga. Kāore i te piki ake te hiahia mō ngā koranu konumohe, engari kua heke iho. He take nui anō hoki tēnei e puta ai te āhua teitei o te kaha whakaputa konganuku silicon, engari he tino iti te tere whakahaere, ā, he nui te korenga o te silicon konganuku kounga teitei i te mākete.
3. Te āhua o te whakaputanga i te tau 2021
E ai ki ngā tatauranga, mai i Hanuere ki Hūrae 2021, i eke te kaweake whakarewa silicon a Haina ki te 466,000 tana, he pikinga tau-ki-te-tau o te 41%. Nā te iti o te utu o te silicon whakarewa i Haina i ngā tau kua pahure ake nei, me te tiaki taiao me ētahi atu take, he iti te tere whakahaere o te maha o ngā umanga utu nui, he kati tika rānei.
I te tau 2021, nā te nui o te tuku, ka piki ake te tere whakahaere o te silicon whakarewa. Kāore i te rawaka te tuku hiko, ā, he iti iho te tere whakahaere o te silicon whakarewa i ērā o ngā tau kua hipa. He iti te nui o te silicon me te polysilicon e hiahiatia ana i tēnei tau, he nui ngā utu, he nui ngā tere whakahaere, ā, kua piki ake te hiahia mō te silicon whakarewa. Nā ngā āhuatanga whānui i arahi ki te korenga nui o te silicon whakarewa.
Tuawhā, te au o te whakarewa silicon i te heke mai
E ai ki te āhuatanga o te tuku me te tono i tātarihia i runga ake nei, ko te ia o te heke mai o te silicon whakarewa e whakawhirinaki ana ki te otinga o ngā āhuatanga o mua.
Tuatahi, mō te hanga tūpāpaku, he nui tonu te utu, ā, ka tīmata anō te hanga i ētahi o ngā mahi tūpāpaku, engari ka roa pea te wā.
Tuarua, kei te haere tonu ngā aukati hiko o nāianei i ētahi wāhi. Nā te korenga o te hiko, kua whakamōhiotia ētahi wheketere silicon mō te motuhanga hiko. I tēnei wā, kei te kati tonu ngā oumu silicon ahumahi, ā, he uaua ki te whakaora i aua oumu i roto i te wā poto.
Tuatoru, ki te noho teitei tonu ngā utu o roto, e matapaetia ana ka heke te kaweake. Ko te nuinga o te konganuku silicon o Haina ka kaweakehia ki ngā whenua Āhia, ahakoa he onge te kaweake ki ngā whenua o Ūropi me Amerika. Heoi, kua piki ake te hanga silicon ahumahi o Ūropi nā te teitei o ngā utu o te ao i ēnei rā. I ētahi tau kua pahure ake nei, nā te painga utu o roto o Haina, he painga tino nui te hanga konganuku silicon a Haina, ā, he nui te rahinga kaweake. Engari ki te teitei ngā utu, ka piki ake hoki te kaha whakaputa a ētahi atu rohe, ā, ka heke te kaweake.
Waihoki, mō te tono i raro iho, ka nui ake te hanga silicon me te polysilicon i te haurua tuarua o te tau. Mō te polysilicon, ko te kaha whakaputa kua whakaritea mō te hauwhā tuawhā o tēnei tau he tata ki te 230,000 tana, ā, ko te katoa o te hiahia mō te silicon whakarewa e matapaetia ana he tata ki te 500,000 tana. Heoi, kāore pea te mākete kaihoko hua whakamutunga e pau i te kaha hou, nō reira ka heke te tere whakahaere whānui o te kaha hou. I te nuinga o te wā, e matapaetia ana ka haere tonu te korenga o te konganuku silicon i roto i te tau, engari kāore te āputa e tino nui. Heoi, i te haurua tuarua o te tau, ka raru ngā kamupene silicon me te polysilicon kāore e uru ana ki te silicon whakarewa.
