Description

Technical Field

[0001] The utility model relates to the technical field of catalyst coating equipment, in particular to catalyst coating firmness testing equipment. Background Art

[0002] Catalyst coating refers to the process of applying catalyst materials to the surface of other materials in the form of a coating. A catalyst is a substance that can accelerate the rate of a chemical reaction, and catalyst coating is the process of evenly covering the catalyst material on the surface of other materials to enhance or change the chemical reaction performance of the material under specific conditions. The catalyst coating may be subjected to various forces during use, such as mechanical stress, chemical corrosion, temperature changes, etc. Appropriate testing can evaluate whether the coating can maintain its integrity and performance stability under these conditions.

The testing equipment of the utility model includes a compressed air generating device, a compressed air buffer tank and a pressure display, a compressed air dispersion device, a catalyst fixing device, a dust recovery device and a control system. The integral catalyst to be tested is placed on the catalyst fixing device. After fixing, the compressed air generating device provides compressed air of the required pressure, and the compressed air dispersion device acts on the tested catalyst, and the test time is controlled by the time control system. This testing equipment can be used for integral catalysts within any diameter range, and can be tested according to the coating firmness requirements of different integral catalysts. The test conditions are closer to the use conditions of the integral catalyst, and effectively reflect the coating firmness of the catalyst.

The shedding of the coating can be calculated by the weight before and after purging, but the dust is not easy to collect and bear the weight, and cannot be felt intuitively and quickly. Therefore, in view of the above-mentioned deficiencies, a new catalyst coating firmness testing equipment is proposed. Utility Model Content
