In the insulation construction of the generator body in thermal power plants, wire mesh is the core binding and fixing component of soft insulation materials such as ceramic fiber blankets. Many construction and procurement friends often struggle: should galvanized wire mesh or stainless steel wire mesh be used for generator insulation wire mesh? Combining GB50264, GB50126, and DL/T insulation standards for the power industry, we will provide a clear overview of the selection logic for everyone.

What is the temperature resistance level requirement for the plastering material used in power plants? The power plant plaster belongs to the "outer protective layer of the insulation layer", not the refractory lining. The temperature resistance of the plaster calibration needs to be higher than the hot surface temperature of the inner insulation layer, with a safety margin reserved. All requirements include A1 level non flammability, low loss on ignition, thermal shock resistance, vibration resistance, no cracking, and no corrosion of the base material.

What type of ceramic fiber blanket should be selected for thermal power plants? In thermal power plants, the selection of ceramic fiber blankets needs to be determined based on the actual operating temperature, working environment, and mechanical requirements of the equipment location. There is a huge temperature difference in different parts of the power plant, and there is no one level that can "eat the whole plant". After receiving a customer's inquiry, the editor from Rosewool Insulation Refractory Co.,Ltd. recommends a type selection plan for ceramic fiber blankets in power plants;

What are the main reasons for the failure of insulation materials in power plants? What types of insulation materials are used in power plants? Among the core causes of insulation material failure in power plants, moisture is the main reason for failure, and shrinkage cracking and vibration detachment are common accompanying manifestations. Wind erosion only accounts for a low proportion in unprotected outdoor areas.

Common overheating areas in power plant operating equipment (mainly in thermal power plants, divided into main body, pipelines, valves, and auxiliary equipment, all of which are prone to insulation failure and surface overheating hotspots);

What are the reasons for the temperature of the equipment shell in the thermal power plant exceeding the design value, causing local overheating, and infrared temperature measurement exceeding the standard? Thermal power plants generally refer to "pipelines, valves, turbine bodies, heaters, headers, furnace bodies, flue gas ducts", etc. The designed outer wall temperature is usually the temperature of the outer surface of the insulation layer (not the temperature of the metal base material), and the vast majority is "insulation failure", with a few being abnormal body structure/medium.
