Kukula kwa msika wamakampani aku China oyeretsa kwambiri a alumina mu 2021

Malinga ndi Lipoti la Research pa kafukufuku ndi chiyembekezo chandalama chamakampani aku China oyeretsedwa kwambiri a aluminiyamu (Kope la 2021) lotulutsidwa ndi Limu chidziwitso chaupangiri, aluminiyamu yoyera kwambiri ili ndi ubwino wa kuuma kwakukulu, mphamvu yayikulu komanso kukana kutentha kwambiri, ndipo imagwiritsidwa ntchito kwambiri pamagetsi, semiconductor ndi mafakitale ena.Aluminium yoyera kwambiri imagwiritsidwa ntchito kwambiri popanga magawo a ceramic a mabwalo ophatikizika ndi masensa agalimoto.Ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri.

Ku China, mphamvu mwadzina ya mabizinesi ambiri apakhomo omwe amapanga aluminiyamu yoyera kwambiri ndi matani masauzande ambiri.M'malo mwake, ambiri aiwo amakhazikika m'misika yotsika monga phosphors.Komabe, chiyero cha mabizinesi ena apakhomo chafika pamwamba pa 4n5, ndipo palibe kusiyana ndi mabizinesi otsogola akunja pankhani ya chiyero.Kugwiritsa ntchito kolowera gawo la safiro kumatha kuzindikira kulowetsa m'malo.Komabe, potengera kukula kwa tinthu, mabizinesi akunja amatha kukwaniritsa pansi pa 30nm (nm), ndipo mabizinesi ambiri apakhomo amakhalabe ndi kusiyana kwina.Choncho, pakali pano, alumina kwa lithiamu batire diaphragm makamaka amaperekedwa ndi Sumitomo mankhwala ndi opanga ena akunja.

M'malo ogwiritsira ntchito safiro, mabizinesi opanga aluminiyamu apamwamba kwambiri amakhala ndi zabwino zodziwikiratu zamitengo ndipo ali pafupi ndi makasitomala, zomwe mosakayikira zidzakhala ndi zabwino zambiri.Nthawi yomweyo, m'munda wa aluminiyamu wapamwamba kwambiri, ndikupita patsogolo kwaukadaulo wamabizinesi apakhomo, mabizinesi apakhomo omwe ali ndi ukadaulo wotsogola komanso magwiridwe antchito okwera mtengo adzazindikira mwachangu kulowetsa m'malo, ndikulowa msika wapadziko lonse lapansi kuti atumize katundu wambiri. - aluminiyamu woyera.

Chifukwa cha kukhazikika kwa zotengera zapamwamba komanso kutsika kwatsika pamsika wa aluminiyamu wapakhomo, zikhala njira yachitukuko ya alumina yoyera kwambiri kuti ilowe m'malo mwazogulitsa kunja ndikukwaniritsa zomwe msika wapakhomo ukufunikira.

Kukula kwa mafakitale a aluminiyamu ku China kwachedwa kwambiri ndipo kudakali koyambirira.Pakadali pano, njira yayikulu yopanga ndikuwongolera njira ya Bayer.Panthawi imeneyi, zoweta zoweta makamaka 4N aluminiyamu, ndipo pali mabizinesi ochepa zoweta kuti akhoza kupanga mankhwala 5N.Mu 2019, kutulutsa kwa aluminiyamu yaku China yoyera kwambiri kunali matani 7600, kufunika kwake kunali matani 15700, ndipo kutulutsa kunja kudafika matani 8100.Mu 2020, kutulutsa kwa aluminiyamu yaku China yoyera kwambiri kunali matani 8280, zofunidwa zinali matani 17035, ndipo kutulutsa kunja kudafika matani 8750.

Shandong Zhanchi New Material Co., Ltd (Shanghai Chenxu Trading Co.,Ltd) yopangidwa ndi alumina yoyera ya 5N 99.999, imadzaza kusiyana kwaukadaulo wapakhomo ndikuphwanya ulamuliro waukadaulo wakunja.
