Today, with the advocacy of ecologically friendly and sustainable development of industry, many countries around the world have taken "green chemistry" as an important direction for the development of the chemical industry in the new century.

In the process of evaporation treatment of wastewater from by-product ammonium salt (including organic amine) of chemical industry, some ammonium salt will be hydrolyzed and converted into ammonia gas (or organic amine). They enter into the condensate with the evaporation and condensation of water vapor, resulting in the ammonia nitrogen in the condensate exceeding the standard (according to the evaporation process, the ammonia nitrogen content generally varies from 200-1000 mg/L), unable to be discharged or reused, which brings difficulties to the production enterprises, but also causes waste of resources.

The reasonable and effective treatment of waste water, waste gas and solid waste is the core of environmental protection work. With the in-depth development of national environmental protection work, the waste gas treatment work has gradually become the focus of environmental protection and attracted more and more attention, and the emission standard of volatile organic compounds in waste gas has become more and more strict. Volatile organic compounds (VOCs) are a kind of main air pollutants in the exhaust gas, mainly some low boiling point, volatile organic compounds, which are produced in the chemical production process of raw material reagents or solvents volatilization, which not only causes material loss to related production enterprises, but also brings difficulty to the treatment of exhaust gas.

Lactic acid is a kind of multi-purpose organic acid and it is also one of the three recognized organic acids in the world.

Citric acid, scientific name 2-hydroxypropane-1,2,3-tricarboxylic acid, is widely used in food, medicine, cosmetics and other industrial fields. The production of citric acid is mainly through biological fermentation. In the process of fermentation, salt, pigment and other impurities will inevitably be produced. It is necessary to achieve the impurity removal and purification of citric acid through necessary refining process to meet the requirements of relevant standards.

Sunresin and its subsidiaries fully support to fight against the coronavirus.

The Aquatech 2019 edition of the major biennial water trade show was held again at the RAI Exhibition Center in Amsterdam, Netherlands 4th-8th Nov. As the world's leading brand of water treatment exhibition it gathered water related high-quality manufacturers, many technologies, service providers or institutions as well as professional buyers and countless visitors in a strong business atmosphere.

When it comes to resin cotton, there are still many people who don't know what it is. In fact, there are many other names, such as non-rubber cotton, hot air cotton, Khmer elastic cotton and so on. The main components of resin cotton are polyester fibers and 4080 low melting point fibers. In the production process, 4080 low melting point fibers are used instead of adhesives, and the combing and netting technology is adopted. The product has good elasticity. The research and development of China resin manufacturers has always been a professional level.
