產品描述:
滑石瓷結構陶瓷作為裝置構件,一般使用在絕緣設備上,如各類高頻瓷器,燈頭燈座、陶瓷電容器等領域。根據其結構,可以選擇不同的成型工藝制造(例如:熱壓鑄、干壓、等靜壓、擠壓成型等);并經過1390℃高溫燒制而成。如有需要,可以在進行表面施釉處理。
Product Instruction:
This kind of product called steatite structural ceramic , which usually used in different fields like various steatite ceramic, ceramic lamp holder, and so on, is used as assembling constructional element, it is normally used in dielectric equipments. According to the structural features, we may choose different forming methods to make(EX : thermal casting ,Dry - pressing ,Iso-pressing , Extrusion and etc); and sintered under 1390℃. If necessary, it can also be glazed on surface in further process.
