1. Kodi silicon yachitsulo ndi chiyani?
Silicon yachitsulo, yomwe imadziwikanso kuti silikoni yamafakitale, idapangidwa ndi chitsulo chosungunula cha silicon dioxide ndi carbonaceous reduction agent mu ng'anjo ya arc yomira. Chigawo chachikulu cha silicon zambiri pamwamba 98,5% ndi pansi 99,99%, ndi zosafunika otsala chitsulo, zotayidwa, calcium, etc.
Ku China, chitsulo pakachitsulo kaŵirikaŵiri amagawidwa m'makalasi osiyanasiyana monga 553, 441, 421, 3303, 2202, 1101, ndi zina zotero, zomwe zimasiyanitsidwa ndi chitsulo, aluminium ndi calcium.
2. Ntchito munda wa zitsulo silicon
Zomwe zimagwiritsidwa ntchito pansi pazitsulo zachitsulo zimakhala makamaka silicon, polysilicon ndi aluminiyamu. Mu 2020, chiwopsezo chonse cha China chili pafupifupi matani 1.6 miliyoni, ndipo chiŵerengero cha mowa chili motere:
Silika gel osakaniza ali ndi zofunika kwambiri pa zitsulo pakachitsulo ndipo amafuna mankhwala kalasi, lolingana chitsanzo 421 #, kenako polysilicon, ambiri ntchito zitsanzo 553 # ndi 441 #, ndi zotayidwa aloyi zofunika ndi otsika kwambiri.
Komabe, m'zaka zaposachedwa, kufunikira kwa polysilicon mu silicon organic kwawonjezeka, ndipo gawo lake lakhala lalikulu komanso lokulirapo. Kufunika kwa ma aloyi a aluminiyamu sikunangowonjezereka, koma kwachepa. Ichinso ndi chinthu chachikulu chomwe chimapangitsa kuti zitsulo zopanga zitsulo za silicon ziziwoneka ngati zapamwamba, koma kuchuluka kwa ntchito kumakhala kotsika kwambiri, ndipo pali kuchepa kwakukulu kwa zitsulo zachitsulo zapamwamba pamsika.
3. Momwe mungapangire mu 2021
Malinga ndi ziwerengero, kuyambira Januware mpaka Julayi 2021, zogulitsa zachitsulo za silicon ku China zidafika matani 466,000, kuwonjezeka kwa chaka ndi 41%. Chifukwa cha mtengo wotsika wa silicon yachitsulo ku China m'zaka zingapo zapitazi, kuphatikizapo kuteteza chilengedwe ndi zifukwa zina, mabizinesi ambiri okwera mtengo amakhala ndi ntchito zochepa kapena amatsekedwa mwachindunji.
Mu 2021, chifukwa cha kupezeka kokwanira, magwiridwe antchito a silicon yachitsulo adzakhala apamwamba. Mphamvu yamagetsi ndi yosakwanira, ndipo chitsulo chogwiritsira ntchito silicon ndi chochepa kwambiri kuposa zaka zapitazo. Silicon ya mbali yofunidwa ndi polysilicon ndiyosowa chaka chino, ndi mitengo yokwera, mitengo yayitali yogwirira ntchito, komanso kuchuluka kwa kufunikira kwa silicon yachitsulo. Zinthu zambiri zapangitsa kuchepa kwakukulu kwa silicon yachitsulo.
Chachinayi, tsogolo la silicon yachitsulo
Malinga ndi momwe zinthu zilili komanso zofunikira zomwe zafufuzidwa pamwambapa, tsogolo la silicon yachitsulo makamaka zimadalira yankho la zinthu zam'mbuyomu.
Choyamba, kupanga zombie, mtengo umakhalabe wokwera, ndipo kupanga zombie kuyambiranso kupanga, koma zitenga nthawi.
Chachiwiri, mipiringidzo yamagetsi yamakono m'malo ena ikuchitikabe. Chifukwa cha kuchepa kwa magetsi, mafakitale ena a silicon adadziwitsidwa za kudula kwa magetsi. Pakalipano, palinso ng'anjo za silicon za mafakitale zomwe zatsekedwa, ndipo n'zovuta kuzibwezeretsa kwakanthawi kochepa.
Chachitatu, ngati mitengo yapakhomo ikhalabe yokwera, zogulitsa kunja zikuyembekezeka kuchepa. Chitsulo cha silicon cha China chimatumizidwa makamaka kumayiko aku Asia, ngakhale sichimatumizidwa kumayiko aku Europe ndi America. Komabe, kupanga masilikoni aku Europe kwakula chifukwa chamitengo yaposachedwa yapadziko lonse lapansi. Zaka zingapo zapitazo, chifukwa cha mtengo wapakhomo waku China, kupanga kwa China chitsulo cha silicon kunali ndi mwayi wokwanira, ndipo kuchuluka kwa zotumiza kunja kunali kwakukulu. Koma mitengo ikakwera, madera ena adzawonjezeranso mphamvu zopangira, ndipo zogulitsa kunja zidzachepa.
Komanso, ponena za kufunikira kwa pansi, padzakhala silicon ndi polysilicon zambiri mu theka lachiwiri la chaka. Pankhani ya polysilicon, mphamvu yopangira yomwe idakonzedwa mu gawo lachinayi la chaka chino ndi pafupifupi matani 230,000, ndipo kufunika kokwanira kwa silicon yachitsulo kukuyembekezeka kukhala matani pafupifupi 500,000. Komabe, msika wa ogula zinthu zomaliza sungathe kugwiritsa ntchito mphamvu zatsopano, kotero kuti kuchuluka kwa magwiridwe antchito atsopano kudzachepa. Nthawi zambiri, kuchepa kwa zitsulo za silicon kukuyembekezeka kupitilira chaka chonse, koma kusiyana sikudzakhala kwakukulu. Komabe, mu theka lachiwiri la chaka, makampani a silicon ndi polysilicon osaphatikizapo silicon yachitsulo adzakumana ndi zovuta.
