Problems solved by technology

[0003] At present, the processing method of the honeycomb carrier of the internal combustion engine exhaust gas purifier is rolling. After the original plate is subjected to multi-stage hot rolling and cold rolling, a thin material with a thickness of 50 μm is finally produced, and the existing processing method requires multiple processes. Among them Involving heat treatment and rolling process, the process is cumbersome and time-consuming, the cost is high, the quality stability is poor, the product yield is low, and some waste is generated. Therefore, we propose a 3D printing technology-based exhaust gas purifier for internal combustion engines. Preparation

Abstract

The invention discloses a preparation method of an internal combustion engine tail gas purifier based on a 3D printing technology. The preparation method comprises the following steps that S1, raw materials are prepared, specifically, ingot casting and melting are carried on required metal raw materials, and corresponding alloy is added into molten metal according to the actual requirements of a honeycomb carrier of the internal combustion engine tail gas purifier; S2, the raw materials are subjected to vacuum atomization powder preparation, specifically, the molten metal is prepared into metal powder through a vacuum atomization powder preparation method; S3, the honeycomb carrier of the internal combustion engine tail gas purifier is prepared; and S4, polishing finishing and acid pickling are conducted. Compared with an existing preparation method, the preparation method of the internal combustion engine tail gas purifier based on the 3D printing technology is simple in technologicalprocess, the finished product composition material is uniform, the product yield is high, the procedures of heat treatment, hot rolling, cold rolling and welding in an existing preparation method areomitted, the risk of product scrapping is reduced, short-process green and clean manufacturing is achieved, and energy is also saved.

Description

technical field [0001] The invention belongs to the field of exhaust purifiers for internal combustion engines, and more specifically relates to a method for preparing an exhaust purifier for internal combustion engines based on 3D printing technology. Background technique [0002] Honeycomb carrier is a commonly used core component for various types of exhaust pollution control. By coating catalyst or adsorbent on the appropriate type of honeycomb carrier, it can effectively remove harmful components in exhaust gas and realize the control of exhaust gas pollution. Among the various properties of the honeycomb carrier, the specific surface area is the key factor for the exhaust gas purification effect. The high specific surface area can increase the contact area between the coating material and the exhaust gas, and improve the purification efficiency of the exhaust gas. [0003] At present, the processing method of the honeycomb carrier of the internal combustion engine exh...
