Menene bambanci tsakanin martani bonded da sintered silicon carbide?

Idan ya zo ga yumbu na silicon carbide, akwai manyan nau'ikan iri biyu:amsa bonded silicon carbideda kuma sintered silicon carbide. Duk da yake nau'ikan yumbura guda biyu suna ba da matakan tsayin daka da juriya, akwai wasu bambance-bambance masu mahimmanci tsakanin su biyun.

Bari mu fara da martani bonded silicon carbide tukwane. Waɗannan tukwane suna tsakanin 85% da 90% silicon carbide kuma sun ƙunshi wasu siliki. Matsakaicin zafinsu shine 1380 ° C. Ɗaya daga cikin manyan fa'idodin yumbu na silicon carbide mai ɗaukar martani shine cewa ana iya daidaita su zuwa manyan girma da siffofi. Wannan ya sa su kayan aiki masu kyau don ƙirƙirar samfurori na musamman da masu sana'a. Bugu da ƙari, ƙarancin haɓakar haɓakawa da ingantaccen juriya na waɗannan tukwane ya sa su zama mashahurin zaɓi a cikin masana'antar guguwar ma'adinai.

Silicon carbide mara ƙarfi mara ƙarfi yana da babban abun ciki na silicon carbide, wanda zai iya kaiwa sama da 99%, kuma mafi girman juriya na zafin jiki shine 1650°C. An gabatar da wani ƙayyadaddun ƙayyadaddun ƙayyadaddun haɓakawa yayin aikin sintiri, wanda ke sa SiC mara matsi mara ƙarfi don kera ainihin sassan SiC. Saboda babban madaidaicin sa, ana amfani da siliki carbide mara ƙarfi mara matsi don yin gyare-gyare da daidaitattun sassa masu jurewa.

Baya ga madaidaicin gyare-gyare da sawa sassa, babban kayan aikin kiln don masana'antar sinadarai na iya yin amfani da mafi girman juriya na zafin jiki na silicon carbide mara ƙarfi. Ga waɗanda ke neman ingantaccen bututun musayar zafi don kayan aikinsu na sarrafa sinadarai, silicon carbide mara matsi tabbas zaɓin abu ne mai yuwuwa.

Gabaɗaya, haɗin kai da haɗin kai da rashin matsi na yumbura SiC, kodayake kowanne yana da fa'ida da rashin amfaninsa, sun dace da masana'antu da aikace-aikace daban-daban. Idan kuna buƙatar samfur na musamman ko girman girman da zai iya jure lalacewa, abin da ke da alaƙa da silicon carbide yumbu na iya zama zaɓin da ya dace a gare ku. Don ƙarin sassa masu laushi waɗanda ke buƙatar jure yanayin zafi, silicon carbide mara ƙarfi na iya zama mafi kyawun zaɓi. Ko da wane nau'in yumburan siliki carbide da kuka zaɓa, zaku iya kasancewa da tabbaci cewa zai samar da dorewa da dorewar aikin ku.
