Water treatment chemicals, also known as water treatment chemicals, mainly refer to chemicals used in industrial water treatment, including scale inhibitors, corrosion inhibitors, bactericidal algaecides, etc. for industrial water treatment such as cooling water, boiler water, sewage, and oil field water. Defoaming agent, flocculant, etc. In addition, activated carbon and ion exchange resins are also important water treatment chemicals. Water treatment is of great significance in improving water quality, preventing environmental pollution, ensuring efficient and safe operation of industrial production, saving energy and water, and protecting the environment.
Gas treatment chemicals refer to chemicals that adsorb, filter, and purify organic waste gas generated during industrial production. Organic waste gases usually include formaldehyde, benzene series such as benzene, toluene and xylene, ethyl acetate, resin organic waste gas, additive organic waste gas, etc. They are generally toxic and harmful, insoluble in water, soluble in organic solvents, and difficult to treat. Common gas treatment agents mainly include activated carbon, inorganic salt sodium bicarbonate, sodium carbonate, etc.
Fibers used in construction engineering are generally thin and long polymer materials with certain tensile strength, elastic modulus and ultimate elongation. They are usually added to concrete and can be evenly distributed in the concrete to strengthen the concrete structure, thereby increasing the service life of the concrete structure building. Common fiber chemicals mainly include glass fiber, polyethylene fiber, steel fiber, etc.
Food additives refer to food additives that are added to food during production, processing, storage and other processes in order to improve food quality and its color, aroma and taste, change the structure of food, prevent food oxidation, corruption, deterioration and for the needs of processing technology. Natural substances or chemically synthesized substances. Common sweeteners such as food-grade glucose and sour agents such as citric acid add a lot of flavor to various foods.
Disinfection chemicals, often referred to as disinfectants, refer to preparations used to kill pathogenic microorganisms on transmission media and render them harmless. After primary or secondary treatment of wastewater, the water quality is improved and the bacterial content is greatly reduced, but its absolute value is still considerable, and there is the possibility of pathogenic bacteria. Therefore, wastewater should be disinfected before being discharged into water bodies. Commonly used disinfectants include hypochlorous acid. Hypochlorous acid disinfectants come in the form of liquid chlorine, bleaching powder, bleaching powder essence, chlorine tablets, sodium hypochlorite, etc. They mainly perform disinfection through HCIO.
In the modern industrial production process, equipment and parts are made of carbon steel, stainless steel, copper and alloys, aluminum and alloys and other materials. Metals and their products are often contaminated with various dirt and pollutants on the surface during processing. Cleaning is the key to metal surfaces. a vital part of the process. The cleaning environment is mainly divided into neutral, acidic and alkaline. According to the difference of the cleaning substrate, the appropriate cleaning agent must be selected. Commonly used acidic cleaning agents mainly include oxalic acid, amino acids, and alkaline cleaning agents are mainly caustic soda.
Agricultural chemicals refer to materials such as fertilizers, growth regulators and other inputs in agricultural production. Their use can promote the production of edible agricultural products and play an important role in the sustained and rapid development of agriculture. Fertilizers commonly used in agriculture are nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, urea, etc., which is very helpful to crop growth.
Hazardous chemicals refer to highly toxic chemicals and other chemicals that are poisonous, corrosive, explosive, flammable, and combustion-supporting, and are corrosive to the human body, facilities, and the environment. For example, if the solution of strongly alkaline sodium hydroxide or strongly acidic oxalic acid splashes on the skin, especially the mucous membrane, it can form a soft shell and penetrate into deep tissues, posing a risk of burns. Enterprises should pay more attention to standardized use during production and use, as chemicals may cause safety accidents.
There are various types of chemicals that play different roles in different industrial production. For example, talc powder can be used in both the ceramic and plastic industries, as well as in the building materials industry. Sodium sulfate is used in textiles to prepare vinylon spinning coagulants, and in glass manufacturing, it can also replace soda ash as a co solvent. As long as used properly, each chemical material can play an important role in different fields. With the development of the national economy, the development and application of fine chemicals will continue to expand, and new categories will also continue to increase.
