Boiler insulation material selection: ceramic fiber blanket model revealed
Recently, the discussion on boiler insulation materials is hot again, among which ceramic fiber blanket has attracted much attention because of its excellent thermal insulation performance and wide range of applications. So, what type of ceramic fiber blanket should be chosen for boiler insulation.
China's refractory products
Based on the present, look to the future, the establishment of many varieties, different grades of refractory products.
Manufacturing process of ceramic fiber
There are three methods for making ceramic fibers: the spinning method, the blowing method and the spinning method. The ceramic fiber in the ceramic fiber paper is commonly used in the blowing method. The wire blowing method is to spray the molten mixed raw materials to the peripheral surface of the high-speed disc in a trickle state under the pressure of a rare gas. Under the pulling force of the high-speed rotation of the disc, it is spun into filaments and coiled on the disc to obtain ceramic fibers of several microns.
Application Prospect of Ceramic Fiber
Compared with organic polymer membrane, ceramic membrane has many special advantages, such as heat resistance, solvent corrosion resistance, high mechanical strength, uniform and narrow pore size distribution, controllable microstructure, long service life, etc., so it can meet the particularly harsh requirements. It has a wide application prospect in petrochemical industry, chemical industry, metallurgical industry, food industry, green energy-saving engineering, new energy and other fields, and is receiving increasing attention. However, the practical ceramic membrane is generally asymmetric structure, the membrane preparation process is complicated, the manufacturing time is long, and the cost is high. In addition, the commercial ceramic membrane generally adopts a multi-channel tubular configuration, the thickness of the membrane tube is thick, and the packing density of the membrane is low, resulting in a small filtration area per unit volume and low separation efficiency.
Refractory fiber composition: revealing its unique properties and composition
Recently, the research on the composition of refractory fiber has made new progress, and this material has attracted much attention because of its excellent fire resistance. Next, let's explore the composition of refractory fiber and understand what makes this material unique.
