1. Wastewater analysis
. Domestic sewage
The water quality of domestic sewage is very stable, but it is turbid, dark in color, smelly, slightly alkaline, and generally does not contain toxic substances. Domestic sewage is very suitable for the reproduction of microorganisms and contains a large number of bacteria (including pathogenic bacteria), viruses and parasite eggs.
The solid matter contained in domestic sewage is .%.%, of which dissolved solids account for about %% of the solid mass, mainly various inorganic salts and soluble organic substances, and organic components account for more than % of its suspended solids. Sewage contains nutrients such as nitrogen and phosphorus.
.Industrial wastewater
Industrial wastewater is wastewater discharged during industrial production. Its composition and properties vary greatly. In addition to cooling water being relatively clean, most of it contains pollutants. Some contain organic matter, some contain toxic and harmful substances (for example, the sewage discharged from the coking plant, called phenol water, contains phenol, ammonia, sulfide and cyanide, etc.), and some have complex components and need to be treated before they can be discharged into the environment. Water bodies, and different industrial wastewater should undergo different treatments.
2. Product physical properties
Water-based polyester composite anti-corrosion
Waterproof coating
The film-forming materials are water-based polyester, fluorocarbon resin
, polyethylene, polyethylene A mixed liquid system of chlorotrifluoroethylene, tertiary carbonic acid and polysiloxane resins.
Polyethylene has good stability, extensibility, water resistance and weather resistance because there are no double bonds in the main chain. Polychlorotrifluoroethylene has good acid resistance, alkali resistance, salt resistance and mold resistance. It is used for tertiary carbonic acid. Polysiloxane has a strong defoaming and wetting effect due to the linking gene that reacts with the inorganic curing agent and grafts with the resin, especially with the concrete surface. , which is conducive to the full miscibility of powder and liquid materials, and has good penetration ability.
The powder of flexible thick-build vinyl ester resin anti-corrosion and waterproof coating is selected from
ceramic
raw materials, graphite, and flake raw materials. Ceramic raw materials are one of the most stable materials among inorganic powders at present. , has low water absorption and is used industrially to make acid-resistant bricks.
, Flexible thick-build vinyl ester resin anti-corrosion and waterproof coating. The flexible coating film has a good repair and shielding effect on the fine cracks in concrete. The water-based polyester coating film has good acid resistance, alkali resistance, salt resistance and mold resistance. Performance The vinyl ester resin anti-corrosion coating film has a tight structure and can be directly applied to the pasting of ceramic tiles. While serving as an adhesive, it forms a continuous and integrated anti-corrosion and waterproof coating film.
3. Product Introduction
High-build vinyl ester resin anti-corrosion and waterproof coating is a two-component water-emulsion elastic anti-corrosion and waterproof coating independently developed and produced by our company. Each batch is divided into groups. The group is made of vinyl ester resin, fluorocarbon resin, polymer emulsion and additives. The group is made of flake graphite and ceramic clay. When in use, mix the two components according to the factory ratio. After several After hours, it solidifies into an overall coating film that is elastic, tough and durable. According to the requirements of the national standard "Anti-corrosion Design Code for Industrial Buildings", it is divided into first-level anti-corrosion (heavy anti-corrosion), second-level anti-corrosion (medium anti-corrosion), third-level anti-corrosion (light anti-corrosion), fourth-level anti-corrosion (slight anti-corrosion), general
Sewage treatment
The plant adopts light anti-corrosion. For example, light anti-corrosion is divided into four levels (slight level), three levels (ordinary level), two levels (enhanced level), and one level (extra enhanced level).
The successful research on high-build vinyl ester resin anti-corrosion and waterproof coatings has added a very good variety of anti-corrosion and waterproof coatings to our country. It has been used in many sewage treatment plants and water supply plants and has achieved ideal results. It has made great contributions to the anti-corrosion and waterproofing of concrete structures in my country, reducing pollution, improving anti-corrosion and waterproofing effects, and creating a green environment. It has been awarded "China's Excellent Green Environmental Protection Products" and "China Engineering Construction" by the Green Building Materials Committee of the National High-tech Construction and Building Materials Industry Committee. Recommended product" honorary title.
4. Product Features
After the film is formed, the product has a large elongation, is elastic, and has good adhesion to the surface of reinforced concrete
It is tough, wear-resistant, water-resistant, oil-resistant, and water-resistant. It is weather-resistant and has excellent freeze-thaw aging resistance. It is especially suitable for anti-corrosion and waterproofing projects on the front and back surfaces of buildings in long-term water immersion environments. Its water resistance meets the requirements of relevant specifications. It is resistant to high temperatures (°C) and below, has strong resistance to alternating dry and wet conditions, and has good anti-microbial and acid, alkali and salt erosion properties. The specially developed primer has strong permeability and adhesion to concrete. It can meet the construction requirements for painting on wet surfaces. It is non-toxic, harmless and pollution-free and can be used in drinking water projects. It can be constructed on both dry and wet substrates. It is easy and safe to construct, has high bonding strength, does not blister or fall off at minus ℃, and has a service life of more than one year without the need for a protective layer.
