Cationic polyacrylamide (PAM) is a copolymer with ionizable groups on the linear molecular chain. Cationic PAM can be used as a thickening, flocculant, drag-reducing, etc. Because of its ionization in water and the adsorption and bridging of particles in the water body, there is more and more research on cationic polyacrylamide for the water treatment […]

Abstract. Marine biofouling not only increases fuel consumption but also affects ship speed. It also accelerates the corrosion of ship hulls and causes serious economic losses. Marine biofouling also increases the risk of marine operations. In this paper, we use benzisothiazolinone controlled slow release technology to modify marine antifouling coatings. It is hoped that the […]
Similar to the working principle of benzotriazoles and benzophenones UV absorbers. The triazine UV absorber molecule also contains an intramolecular hydrogen bond involving a hydroxyl group. And it forms a six-membered ring with N atom. This six-membered ring and the surrounding structure form a conjugate system, and the optical band gap of the conjugate system […]

The new coal chemical industry in China mainly develops from coal to oil, coal to olefin and coal to dimethyl ether. Among them, coal to dimethyl ether has been favored by many enterprises for its unique advantages. With the gradual start-up of plants under construction and the development of DME application technology, DME is expected […]
North China Oilfield Branch of China National Petroleum Corporation (CNPC) and Shanxi Energy Industry Group have reached a cooperation on coal-bed methane development project. CNPC will spend about a year to build the first coal-bed methane field in China. This is the company after the oil, natural gas and other traditional energy, CNPC began to […]
Since the second quarter, the prices of many chemical products have risen wildly. Some selling prices even hit a record high. Sulfur yellow rose by as much as 700%, which is considered the highest price increase in the chemical market. Second, the most representative is concentrated nitric acid. Concentrated nitric acid prices have seen a […]
During COVID-19 prevention and control, people’s hands are constantly exposed to objects contaminated with viruses and bacteria, especially doctors and nurses in hospitals. Therefore, keeping hands clean is one of the effective ways to reduce the risk of novel coronavirus infection. The main characteristic of Polyhexamethylene guanidine hydrochloride (PHMG) disinfectant is its effective sterilization. It can […]
What is Polyhexamethylene biguanide？ Polyhexamethylene biguanide solution system is a new chemical disinfectant developed and researched abroad in recent years. Polyhexamethylene biguanide hydrochloride is a disinfectant that is widely used at present. Studies have shown that it has excellent disinfection properties, low irritation, low toxicity, low use concentration, and fast disinfection speed. Therefore, it is […]
Out of concern for food prices and security, China will focus on the development of non-food fuel ethanol under the principle of not occupying arable land, not consuming large amounts of food, and not damaging the ecological environment. This is the information obtained by the reporter at the “China Biofuel Ethanol Industrialization Development Strategy Seminar” […]
