Example Embodiment

[0036]

[0037] This embodiment provides an experimental device and an experimental method for directional diffusion of ions in cement stone.

[0038] The difference between the experimental device for directional diffusion of ions in cement stone in this embodiment and the experimental device 11 for directional diffusion of ions in cement stone in Example 1 is that the assembly method of the samples is different. Figure 4 It is the assembly schematic diagram of the cement stone test block in the second embodiment of the present invention, such as Figure 4 As shown, in this embodiment, 16 small test blocks of cement stone with a size of 40mm × 40mm × 40mm are spliced ​​into Figure 4 In the shape shown, the interface between each small cement stone test block is smeared with white latex, and then assembled together to obtain a cement stone test block 9 . From a sheet of extruded foam plastic with a thickness of 40mm, cut out Figure 4 2 long strips 10 of the shape shown ...

Abstract

The invention provides an experimental device for directional diffusion of ions in set cement, which is characterized by comprising a closed container which is a cube with an open top surface and one open side surface, and the open side surface of the container is an open side surface; the fan is placed outside the closed container and located in the lateral direction of the open side face; the water storage tank is mounted at the bottom of the closed container; the ultrasonic atomizer is placed in the water in the water storage tank; the timing switch is connected with the ultrasonic atomizer and used for controlling the ultrasonic atomizer to be turned on and turned off; the sample frame is arranged on the open side surface and is used for placing a sample; the movable cover plate covers the top surface of the closed container; the sample is a set cement test block and is formed by splicing a plurality of square set cement small test blocks. The invention provides an experimental method for ion directional diffusion in set cement. The experimental method is characterized in that the experimental device is used for carrying out an ion directional diffusion experiment in the set cement.

Description

technical field [0001] The invention belongs to the field of cement decoration, and in particular relates to an experimental device and an experimental method for directional diffusion of ions in cement stones. Background technique [0002] Cement-based decorative materials have high requirements on appearance, but Portland cement will cause frost after hardening, which significantly affects the decorative effect of this type of product, especially for the appearance of colored products. The frosting product of cement mainly comes from calcium ions and other alkaline ions in the cement stone, which gradually migrate to the decorative surface of the product as the dry and wet conditions of the cement decorative product change, and form white carbonate after carbonization , affecting the appearance of the product. If the blooming product ions can be directionally induced and migrated to the back of the product, thereby preventing them from migrating to the decorative surface,...
