Embodiment 1
[0015] The technical solution adopted in this specific embodiment is: a functional dry powder diatom wall material auxiliary material, which is characterized in that it is composed of the following raw materials in parts by weight: 25 parts of non-calcined high-quality diatomite, nano-TiO2 / diatomite 75 parts of photocatalytic composite materials, 2.7 parts of additives; the additives include 0.2 parts of dry powder wetting agent, 0.5 parts of dry powder dispersant, and 2 parts of dry powder defoamer.
[0016] A preparation method of functional dry powder diatom wall material auxiliary material is characterized in that it comprises the following steps:
[0017] Step 1. Preparation of materials: Accurately weigh non-calcined high-quality diatomite, nano-TiO2 / diatomite photocatalytic composite material, dry powder wetting agent, dry powder dispersant and dry powder defoamer;
[0018] Step 2. Mixing and stirring: Add diatomite, nano-TiO2 / diatomite photocatalytic composite material...
Embodiment 2
[0023] The difference between this embodiment and Example 1 is that it consists of the following raw materials in parts by weight: 30 parts of non-calcined high-quality diatomite, 50 parts of nano-TiO2 / diatomite photocatalytic composite materials, and 1.6 parts of additives; The additives include 0.2 part of dry powder wetting agent, 0.4 part of dry powder dispersant and 1 part of dry powder defoamer.
