Abstract

The invention discloses a diatom plate with a photocatalysis function and a production process thereof. The diatom plate is a laminated diatom plate, and consists of multiple diatom unit layer plates; material layers of the diatom plate comprise surface layers located on two sides of the diatom plate and middle layers located between the surface layers on the two sides; totally 12 to 20 material layers are arranged for the diatom plate; the middle layers of the diatom plate are made of slurry A, and the surface layers of the diatom plate are made of slurry B; the slurry B contains a nano TiO2 / diatomite composite material. In addition, the invention further discloses the production process of the diatom plate with the photocatalysis function. The diatom plate can be used to adsorb indoor toxic and harmful pollutants and continuously decompose organic pollutants, such as formaldehyde, methylbenzene and ammonia gas, adsorbed and captured by the surface of the diatom plate under illumination, the purification efficiency is high, and the purification effect is lasting; the diatom plate has a good moisture regulation function, and is large in specific surface, good in heat conductivity coefficient, high in breaking strength and long in service life.

Description

technical field

[0001] The invention belongs to the fields of mineral materials and applications and inorganic non-metallic materials, and in particular relates to a diatom plate with photocatalytic function and a production process thereof. Background technique

[0002] Diatomaceous earth is a kind of siliceous sedimentary rock with biogenic remains of ancient diatoms. It has the characteristics of looseness, light weight, and porosity, and has a three-dimensional pore structure and nano-pore size distribution. The pore distribution is regular. It is widely used in the preparation of health and environmental protection. , Energy saving and other functional materials. As early as the 1980s, there was the production and application of microporous calcium silicate boards with diatomite and lime as the main raw materials and asbestos as the reinforcing fiber, formed by casting and molding, and cured by high temperature steam. However, the calcium silicate board produced by the...
