Dispersing agent for wet electroceramic body connecting process and wet body-connecting method

Abstract

The invention relates to a dispersing agent for a wet electroceramic body-connecting process and a wet body-connecting method. The dispersing agent is prepared from sodium polyacrylate and is applied to the wet body-connecting process of electroceramic bodies. The dispersing agent is an aqueous solution of the sodium polyacrylate with the weight percentage concentration of 0.2 to 1.5 percent; the using temperature of the dispersing agent is 25 to 50 DEG C in summer and autumn, and 15 to 40 DEG C in winter and spring; and the hydration time is 7 to 35 minutes. The wet body-connecting method by using the sodium polyacrylate as the dispersing agent comprises the following steps of: preparing the dispersing agent, namely weighing the sodium polyacrylate according to the requirement, putting the sodium polyacrylate into a container, adding hot water slowly, and adding water with stirring; dissolving the materials fully, stirring uniformly, and adding water until the required concentration is achieved; and stirring uniformly, and preparing the dispersing agent.

Description

technical field [0001] The invention belongs to the technical field of electric porcelain, and in particular relates to a process method for wet bonding of electric porcelain, in particular to a process method for using sodium polyacrylic acid as a dispersant, supplemented with appropriate proportioning. Background technique [0002] Wet blank joining process is a molding process with a long history in the global electric porcelain industry. It originated in the 1970s. This process has the characteristics of less investment, low cost, high work efficiency, and can produce products with large structural size and complex shapes. , is widely used in the production of electric porcelain. This process is to hydrate the interface of two or several mud sections with dispersant, then connect the mud sections, and then cut them into the required shape. The dispersant is very important in the whole process. The electric porcelain industry has always been Both use soda (sodium carbona...

Problems solved by technology

The second is to make the porcelain brittle and reduce the mechanical strength and thermal shock resistance of the product

The third is that sodium ion is a highly active conductive ion. Under the action of an electric field, it is easy to generate electron migration, reduce the electric strength of the porcelain body, and be broken down during the electrical performance test of the product.
