Environmentally friendly chemistry, also known as green chemistry, is the use of chemical techniques and methods, to fundamentally reduce the appearance and application of raw material, solvent, reagent, products and by-products which are harmful to human health and the environment. Then under the e

The performance characteristics of boiler scale inhibitorThe applicable scope of the power plant boiler scale inhibitor:Power plant boiler scale inhibitor is for thermal power plants, power plant boiler scale inhibitor high pressure boiler operating conditions and water vapor quality standards for t

Water treatment involves the removal of contaminants present in the raw or partly treated water. The major cause of water pollution are microbes, dissolved chemicals and other particulate matter, which originated either naturally or through man-made sources. The objective of all water treatment meth

1. Water TreatmentIn addition to individual processes,we can use soft water in most of the processes in printing and dyeing industry, so chelating agent can be added to chelate the metal ions in water to achieve the purpose of softening water.2. DesizingWhen sizing, some textile mills may add the he

In industrial production, a large amount of industrial cooling water is used. A variety of salts is dissolved in water, such as bicarbonate, carbonate, sulfate, chloride, etc.. Dissolved bicarbonate such as Ca(HCO3)2, Mg(HCO3)2 is the most unstable. The surface of Heat transfer is easy to decompose

1.Inhibition of precipitation function: In the system of scale inhibitor, the ion product’s values of the cationic and anionic precipitates of the fouling component are much larger than the critical precipitated ion product values without the scale inhibitor. 2.Dispersion function: In the presence o

From the earliest use of natural coagulants to primary synthesis of AlC13, FeS04-7H20 or silicone series coagulants, and then to the use of high polymer coagulants (such as PAC, PFS, PASS, PAM, etc.), as well as the upcoming biological coagulant. The process of using coagulants in humans also underg

There are many reasons for scaling in oil field, such as the deposition of impurities in water, the high salinity in water, the scaling out of the carbonate, the pressure, the pH, the temperature and so on. Water injection fouling makes the oil production system clogged and the output is decreasing

Polyaspartic acidPolyaspartic acid ( PASP ) is a new environmental protection scale inhibitor developed by foreign researchers in the past 10 years. Its sodium salt is sodium polyaspartate. It is reported that the sodium salt is biodegradable , non-toxic, non-destructive to ecological environment, a
