随着远红外加热技术的推广应用,以碳化硅、陶瓷等材料做为元件的加热装置越来越多,而用氧化镁管的仍然占有很大的比例。氧化镁管应用远红外加热技术通常有两种方法:一种是用等离子喷涂法;一种在氧化镁管上,进行手工涂刷一层高辐射率涂料。这种方法虽然简易,但涂层不牢固,弊病很多,节电效果不巩固。齐齐哈尔铁东陶瓷厂 With the popularization and application of far-infrared heating technology, more and more heating devices are used as components, such as silicon carbide and ceramics, while magnesium oxide tubes still occupy a large proportion. Magnesia tube far-infrared heating technology is usually used in two ways: one is the use of plasma spraying method; a magnesium oxide tube, hand-painted a layer of high emissivity paint. Although this method is simple, but the coating is not strong, many disadvantages, energy-saving effect is not consolidated. Qiqihar Iron East pottery factory
