Silicon metal news

1. ntchito.

  Silicon metal (SI) ndi chinthu chofunika kwambiri chachitsulo chokhala ndi ntchito zosiyanasiyana. Nazi zina mwazomwe zimagwiritsidwa ntchito kwambiri ndi chitsulo cha silicon:

1. Zida za semiconductor: Chitsulo cha silicon ndi chimodzi mwa zinthu zofunika kwambiri zamagetsi zamagetsi zamagetsi, zomwe zimagwiritsidwa ntchito popanga zinthu zosiyanasiyana zamagetsi, monga transistors, maselo a dzuwa, maselo a photovoltaic, photoelectric sensors, etc. kugwiritsa ntchito silicon yachitsulo ndi kwakukulu kwambiri.

2. Zida za alloy: silicon yachitsulo ingagwiritsidwe ntchito popanga zipangizo za alloy, zomwe zingapangitse mphamvu, kuuma ndi kuvala kukana kwa alloy. Chitsulo chachitsulo cha silicon chikugwiritsidwa ntchito kwambiri pazitsulo zosungunula ndi kuponyera zitsulo, monga zitsulo zosapanga dzimbiri, carbide cemented, alloy refractory ndi zina zotero.

3. Silicate ceramic zipangizo: chitsulo pakachitsulo angagwiritsidwe ntchito pokonzekera silicate ceramic zipangizo, zinthu za ceramic izi zimakhala ndi katundu wabwino kwambiri wotchinjiriza ndi kutentha kwapamwamba kuvala kukana, zomwe zimagwiritsidwa ntchito kwambiri mu mphamvu yamagetsi, zitsulo, mafakitale a mankhwala, zoumba ndi mafakitale ena.

4. Mapangidwe a Silicone: chitsulo cha silicon chingagwiritsidwe ntchito ngati zipangizo zamagulu a silicone kuti apange mphira wa silikoni, utomoni wa silicone, mafuta a silikoni, silikoni ndi zinthu zina. Zogulitsazi zimakhala ndi kukana kwambiri kutentha kwambiri, kukana kutentha, kukana kwa dzimbiri, zomwe zimagwiritsidwa ntchito kwambiri muzamlengalenga, magalimoto, zomangamanga, zamankhwala ndi zina.

5. Minda ina: Chitsulo cha silicon chingagwiritsidwenso ntchito pokonzekera silicon carbon fiber, silicon carbon nanotubes ndi zipangizo zina zogwira ntchito kwambiri, pokonzekera zipangizo zopangira matenthedwe, zokutira zakuthupi, spark nozzles ndi zina zotero.

Nthawi zambiri, chitsulo cha silicon ndi chinthu chofunikira kwambiri m'mafakitale, chomwe chimagwiritsidwa ntchito kwambiri pazinthu zamagetsi, zitsulo, zoumba, zamankhwala, zamankhwala ndi zina. Ndi chitukuko chosalekeza cha sayansi ndi ukadaulo, kugwiritsa ntchito chitsulo cha silicon kukupitilizabe kukula ndi kupanga zatsopano, padzakhala chiyembekezo chokulirapo pamsika.

2.Global kupanga silicon mafakitale.

Pankhani ya mphamvu kupanga: mu 2021, padziko lonse mafakitale pakachitsulo mphamvu kupanga ndi matani 6.62 miliyoni, amene matani 4.99 miliyoni anaikira mu China (SMM2021 ogwira kupanga mphamvu chitsanzo ziwerengero, kupatula Zombie kupanga mphamvu za matani 5.2-5.3 miliyoni), kuwerengera 75%; Kuthekera kopanga kunja kuli pafupifupi matani 1.33 miliyoni. M'zaka khumi zapitazi, mphamvu zopangira zakunja zakhala zokhazikika, ndikusunga matani opitilira 1.2-1.3 miliyoni..

China ndiyomwe imapanga silicon yamakampani, phindu lopangira mabizinesi, aloyi ya photovoltaic/silicone/aluminium ndi misika ina yofunika kwambiri yogulitsira anthu aku China, ndipo pakufunika kukula kwakukulu, kuteteza udindo waukulu wamakampani aku China opanga silicon. Msikawu ukuyembekezeka kuti mphamvu yopanga ma silicon padziko lonse lapansi ikwera mpaka matani 8.14 miliyoni mu 2025, ndipo China idzalamulirabe kukula kwa mphamvu, ndipo kuchuluka kwake kudzafika matani 6.81 miliyoni, kuwerengera pafupifupi 80%. Kutsidya kwa nyanja, zimphona zamafakitale zama silicon zikukula pang'onopang'ono kunsi kwa mtsinje, makamaka kuyang'ana mayiko omwe akutukuka kumene monga Indonesia omwe ali ndi mtengo wotsika wamagetsi.

Pankhani yotulutsa: kuchuluka kwa silicon yamakampani padziko lonse lapansi mu 2021 ndi matani 4.08 miliyoni; China ndiye omwe amapanga silicon yayikulu kwambiri padziko lonse lapansi, ndipo zotulutsa zimafika matani 3.17 miliyoni (data ya SMM kuphatikiza 97, silicon yosinthidwanso), zomwe zimawerengera 77%. Kuyambira 2011, dziko la China laposa dziko la Brazil monga dziko lopanga komanso kugwiritsa ntchito silicon m'mafakitale.

Malinga ndi ziwerengero zapadziko lonse lapansi, mu 2020, Asia, Europe, South America ndi North America, gawo la mafakitale a silicon ndi 76%, 11%, 7% ndi 5%, motsatana. Malinga ndi ziwerengero zapadziko lonse lapansi, kupanga masilikoni akumayiko akunja kumakhala ku Brazil, Norway, United States, France ndi malo ena. Mu 2021, USGS idatulutsa zidziwitso zopanga zitsulo za silicon, kuphatikiza aloyi ya ferrosilicon, ndi China, Russia, Australia, Brazil, Norway, ndi United States zidakhala woyamba kupanga zitsulo za silicon.
