Ⅰ. the field

Construction materials, soil and water conservation, desertification control, agriculture and other fields

Ⅱ. Application status

The new waterproof/water retention technology of micro-particle powder can be widely used in construction materials, agriculture, soil and water conservation and desertification control and other fields.

In the application of waterproof technology: for example, in the construction industry, it can solve the problems of dripping, leakage, and other problems caused by substandard waterproof quality in the field of building waterproof, changing the traditional “ Three felt and four oil ” Waterproofing process, and the same life as the building, reduces the frequency of secondary repair, and has been promoted and used in a number of state-owned enterprises and central enterprises such as China Railway, China Communications Construction, China Hydropower, Xi 'an Construction Engineering Group.

In the application of water retention technology: such as the field of desert treatment, the new water retention and new material technology of micro-particle powder has shown great potential and effect in water storage and sand fixation. The water-retaining agent in the new water-retaining material series of micro-particle powder can make the sand body have the stability, permeability, water retention and effectively store the nutrient and gas content required for plant growth. At the same time, it can make this trait coexist with the modified sand body for a long time, and promote the survival rate of vegetation on sandy land and saline-alkali land to reach more than 95%. The growth time is shortened by 20%, and even water-loving plants such as watermelon and grapes can survive on the sandy land, which fundamentally improves the performance of sand bodies and saline-alkali land, and maximizes the essential requirements of ecological management of sandy wasteland. At present, it has been applied to the Three North Shelterbelt area, and the demonstration area for the Middle East desert environmental management project is in the verification stage (see annex for the contract).

Ⅲ. industrialization situation

Xi 'an Meinan Biotechnology Co., Ltd. now has a plant size of 5000 square meters and a total of 35 employees, including 1 overseas academician, 3 doctors and 3 masters in the R&D team; With 2 fully automated production lines, the production capacity can reach 40,000 tons/year. The company's waterproof mortar series and water-retaining agent series products have established flagship stores in major e-commerce platforms, and the market share has reached 10%; Among them, the water-retaining agent products have successfully signed a $300 million purchase contract with UAE enterprises at the first China (Shaanxi) Brand Goods Dubai Exhibition held at the Dubai Arab Economic and Trade Exchange Center (China Pavilion at World Expo City).

Ⅳ. Technical principles

Microparticle powder waterproof new material series products: It is a 10-2 ~ 10 micron triple-mesh glass ceramic material containing micro-grains formed by silica after microwave special nucleation treatment, combined with the stimulated aerogel reaction, making it hard, soft point and high mechanical strength, with good chemical stability and thermal stability, from the qualitative change, fundamentally changed the traditional construction industry construction process.

Micro-particle powder water retention new material series products: is the reverse research and development of new waterproof technology of micro-particle powder, so that it can actively absorb its own weight more than 1000-1400 times of water, to ensure that it reaches the characteristics of water retention, water retention and so on.

Ⅴ.Key technologies

Technique 1: The plant extraction technique in "A method for extracting tannin from lacquer leaves" is to extract the active chemical from cotton. Raw materials are very common, easy to directly obtain and low cost, which greatly reduces the research and development cost of new water-retaining and waterproof new material technology of micro-particle powder, thereby reducing its production cost.

Ⅵ.Main technical indicators

micro-particle powder new waterproof new material series products

1. Properties: Particle powder new waterproof new material series products are non-toxic, harmless and non-irritating odor, of which particle powder new waterproof powder is white powder; The pH value of the new water-retaining sand is neutral, and the fineness can reach 80 to 100 mesh.

2. High and low temperature freeze-thaw: Excellent and stable waterproof effect can be achieved in the range of -50℃ ~ 250℃.

3. Anti-channeling water: It forms a special film-like structure with the base of the building, which will not channeling water and allow air to enter, achieving the special effect of both waterproof and breathable.

4. Durability: It forms a special membrane structure with the base of the building and has the same life span as the building.

5. Permeability: The new waterproof agent of micro-particle powder can penetrate general objects with water table 5 ~ 8mm.

(2) Micro-particle powder new water retention new material series products

1. Water absorption: can absorb more than 400 ~ 600 times of its own weight;

2. Properties: The new water-retaining powder of micro-particle powder is colorless and pH value is neutral.

7. Scope of application

Microparticle powder waterproof new material series products can be used to solve the construction of nuclear power plants, sewage treatment ponds, garages, basements and roof, wall, toilet water preservation and waterproof projects; The new material of micro-particle powder water retention can be used in desert, saline-alkali land treatment, wetland restoration, crop land improvement, sludge solidification, etc.
