In the process of building piling or shield tunnel construction on the construction site, shield construction, tunnel segment cleaning, grouting pipelines, mortar hopper cleaning, underground flushing, etc. will produce a large amount of sewage, especially in water-rich formations, when encountering water inflow, a large amount of high-concentration mud water will be produced, and the wastewater contains a large amount of kaolin mud particles, cement, etc., and the wastewater applied on the grou

Polyacrylamide (PAM) is one of the effective water treatment agents in the field of sewage treatment, many customers more or less understand the use method and conditions of polyacrylamide (PAM), but there are also many customers who do not understand the use and preservation of polyacrylamide (PAM), carelessness leads to losses. Henan Laixing Water Purification will share the knowledge about the shelf life of polyacrylamide (PAM) and how to preserve polyacrylamide (PAM).

Polyacrylamide (PAM) is a water-soluble polymer linear polymer that is insoluble in most organic solvents and has the advantages of good flocculation performance, low dosage and high efficiency. Polyacrylamide (PAM) is used as a water treatment agent to varying degrees in municipal sewage treatment and industrial wastewater treatment. An example is the treatment of wastewater with polyacrylamide (PAM) in aluminum profile plants, and the production process of aluminum profiles includes degreasing

As a chemical product, polyacrylamide (PAM) not only determines its application field, performance, model and raw material ratio, but also determines its price, one of the important indicators is ionization, the ionization index generally refers to cationic polyacrylamide (CPAM), which is one of the important indicators of cationic series products. As the saying goes, buying right is not wrong, which is very reasonable for polyacrylamide (PAM). The higher the ionization of cationic polyacrylamid

Putty powder is used when decorating houses, especially on walls. Putty powder is a substrate used to repair and level walls, and is a commonly used decorative material. And it is used in large quantities, which provides a good foundation for the next step of decoration (painting wallpaper). Putty powder is generally composed of substrate, filler, water and additives. Polyacrylamide (PAM) is mainly used in sewage treatment and sludge dewatering, in fact, PAM is present in the thickening industry

With the development of the construction industry, the rise of the ceramic industry is an inevitable trend. Ceramic factories use tens of thousands of tons of water every day, making ceramic wastewater treatment a challenge. The concentration of suspended solids in ceramic wastewater is very high, and if it is discharged directly without treatment, it will not only block rivers and wastewater, but also cause water pollution. The main source of ceramic wastewater is the wastewater discharged from

There are three types of ions commonly used in polyacrylamide (PAM): cationic, anionic, and non-ionic. Different ionic forms of polyacrylamide (PAM) have different functions. Since anionic polyacrylamide (HPAM) and cationic polyacrylamide (CPAM) are widely used, many customers don't know how to distinguish between them, but this is understandable, because no matter what type of polyacrylamide (PAM) is the same white particle in appearance, how to distinguish between anionic (HPAM) type and catio

Coking plant wastewater refers to wastewater generated during coal coking, gas purification, chemical product recovery and refining. It mainly comes from coking wastewater and gas cooling wastewater, which accounts for more than half of the total coking wastewater and is the main source of coking wastewater. Gas final cooling water and crude benzene separation water, as well as wastewater generated during the refining process of tar and crude benzene. The following Henan Laixing Water Purificati

Polyacrylamide (PAM) is widely used as a water treatment agent, cationic polyacrylamide (CPAM) and anionic polyacrylamide (HPAM). The main indicators of cationic polyacrylamide (CPAM) are ionization in addition to molecular weight, while the main indicators of anionic polyacrylamide (HPAM) are molecular weight and hydrolysis degree. When customers purchase anionic polyacrylamide (HPAM), they rarely take the initiative to mention the hydrolysis index, so what is the meaning of anionic polyacrylam
