isici sokushisa sic
Izakhi zokushisa ze-Sic zenziwe ngekhwalithi eluhlaza ye-SiCpowder, eyengezwe kwezinye izithasiselo ngokuvumelana nenani lempahla.Izinto zokushisa ze-silicon carbide ziyimikhiqizo engeyona eyensimbi. Uma kuqhathaniswa nezakhi zokushisa ze-metallic, banochungechunge lwezimpawu, ezifana nezinga lokushisa eliphakeme, i-antioxidation, i-anticorrosion, ukwandisa izinga lokushisa ngokushesha, i-coefficient ephansi yokwanda okushisayo nokunye. Ngakho-ke, asetshenziswa kabanzi ezintweni zikagesi nezikazibuthe, izitsha zobumba, imboni ye-metallurgy nokunye.
Izinto zokushisisa ze-Sic Ukucaciswa kanye Nebanga Lokumelana

I-Shandong Zhongpeng Special Ceramics Co., Ltd ingesinye sezixazululo ezintsha ze-silicon carbide zobumba eChina. I-ceramic yobuchwepheshe ye-SiC: Ubulukhuni be-Moh buyi-9 (ukuqina kwe-Moh entsha yi-13), enokumelana okuhle nokuguguleka nokugqwala, ukuhuzuka okuhle kakhulu – ukumelana ne-oxidation. Impilo yesevisi yomkhiqizo we-SiC iyinde izikhathi ezi-4 kuya kwezi-5 kune-alumina material engu-92%. I-MOR ye-RBSiC izikhathi ezi-5 kuye kweziyi-7 kune-SNBSC, ingasetshenziselwa izimo eziyinkimbinkimbi. Inqubo yekhotheshini iyashesha, ukulethwa kunjengoba kuthenjisiwe futhi ikhwalithi ingeyesibili. Sihlala siphikelela ekuphonseni inselelo imigomo yethu futhi sibuyisele izinhliziyo zethu emphakathini.
