Problems solved by technology

Also need to have certain health care function for foamed ceramics, as release negative ion function etc., but if all add negative ion material on foamed ceramic base material and prepare negative ion foamed ceramics, the cost of product will increase a lot, and can cause unnecessary waste. Waste, such as smallpox ceiling products are often reinforced on the back of the foamed ceramic ceiling due to safety considerations, such as coating adhesive, pasting glass fiber mesh, etc., which will cover the base material and cause the negative ion function of the base material to fail. to the desired effect

Abstract

The invention discloses a light-weight anion foamed ceramic. The light-weight anion foamed ceramic with a double-layer structure is formed by using basic foaming powder and anion foaming powder; correspondingly, the invention also discloses a kind of the above-mentioned A method for preparing lightweight negative ion foamed ceramics; the invention effectively improves the utilization efficiency of negative ion materials and reduces the usage amount of negative ion materials by setting layered design and adding negative ion materials only in the surface layer. At the same time, through the combination of formula structure and preparation process, a foamed ceramic with fine and uniform pore size and high strength is prepared.

Description

technical field [0001] The invention belongs to the field of foamed ceramics, and in particular relates to a lightweight negative ion foamed ceramic and a preparation method thereof. Background technique [0002] A series of waste materials such as polishing waste and waste tiles are often a major problem that plagues ceramic manufacturers; in recent years, many ceramic companies and scientific research institutions have begun to carry out a series of projects related to the utilization of ceramic resource waste; although some achievements have been made, but It mostly uses a single type of waste; the main reason is that the composition of different types of waste residues is complex and unstable; a large number of introductions can easily lead to problems such as product foaming and deformation; therefore, how to realize the comprehensive resource utilization of various waste materials in ceramic factories is an urgent need. solved problem. [0003] It is a common way to u...
