The company has been granted 2 more patent authorizations

Recently, the company has received two more patents from the China National Intellectual Property Administration. One is the company's independently developed "Corrosion and Scale Inhibition Combination Agent and Preparation Method", which has successfully obtained national invention patent authorization (patent number: ZL 2017 11247451.5）， This achievement was filed for a patent application on December 1, 2017 and obtained a patent authorization certificate on August 28, 2020; The second is a splash proof device for heat exchangers, which has been granted a national utility model patent authorization (patent number: ZL 2019 2 1732592.0）。 These two patents are respectively the ninth invention patent and the tenth utility model patent authorized by the company, and they are also witnesses to the company's continuous improvement of core technological strength and persistent progress on the road of technological innovation.

The invention patent for "Corrosion and Scale Inhibition Combination Agent and Preparation Method" is a polyether ester compound and its preparation method, as well as a corrosion and scale inhibition combination agent and its preparation method mainly composed of this compound. The compound contains carboxyl hydrophilic chain segments and alkyl hydrophobic chain segments, which are easy to form an adsorption film on the metal surface. The hydrophilic end is adsorbed on the metal surface, and the hydrophobic end is dispersed in the wastewater to prevent ions (Cl, SO42) in the water from corroding the metal substrate. In addition, due to its large number of carboxyl groups, it has the function of chelating calcium and magnesium ions, making it a new type of corrosion and scale inhibitor. It is added to wastewater for zero discharge of circulating cooling water, which not only protects the circulation system from corrosion and scaling of sewage, but also enables the reuse of sewage. Moreover, the microorganisms in the water can achieve the initial treatment effect of sewage during the recycling process.
The utility model patent for an anti splash water device for heat exchangers solves the problem of stains and splashes inside the heat exchanger tubes during the cleaning process, avoiding chemical corrosion and physical damage to operators caused by splashing stains.
