Problems solved by technology

[0005] In this method, in order to test the corrosion performance of gypsum in sodium silicate solution, the actual corrosion environment of sodium silicate solution and gypsum is very different, and it cannot effectively simulate the use environment of gypsum; the method mentioned in this method uses a soft brush to brush the four long surfaces 10 times each, this operation step is the most critical link to determine the dissolution rate of the test block, but the size, hardness and strength of the soft brush in this link will have a very obvious impact on the results, resulting in errors in test results Large, poor repeatability

Abstract

The invention relates to the technical field of chemical equipment, in particular to a device and a method for testing corrosion performance of gypsum. The method comprises a base, a spraying device and a control system, wherein a gypsum test block to be tested is mounted on the base; the spraying device is correspondingly arranged above the base; the control system is used for controlling the spraying device to output a corrosion liquid. The device can simulate an actual corrosion environment of the gypsum to reduce a result error caused by human factors, so that a result has repeatability; through a preferred design of the shape of the inserted test block and control over the corrosion environment, a corrosion process of the gypsum is speeded up, so that the whole testing process is quick and accurate.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a device and method for testing the dissolution performance of gypsum. Background technique [0002] At present, gypsum is a widely used industrial material and building material, which can be used in cement retarder, gypsum building products, ceramic molds, medical food additives, sulfuric acid production, paper fillers, paint fillers, etc. Among them, gypsum building products and ceramic molds are widely used at home and abroad because of their many advantages. However, the poor water resistance of gypsum is also one of its important defects, which limits the application range of gypsum products and the service life of ceramic molds to a certain extent. Therefore, the optimization of the water resistance of gypsum is an important direction in the field of gypsum application research. [0003] Gypsum corrosion is the main reason for the poor water resistance of gyps...
