Welcome plaster expert group to guide our company

In early June, a gypsum expert group of 4 people went to our company (Liaodong Dongda Powder Engineering Technology Co., Ltd.) to carry out comprehensive development of our company's natural gypsum, sulfur gypsum, phosphogypsum special calcin Guidance and technical discussions.

Considering that the equipment has been successfully operated and produced by a certain manufacturer in Beijing, the experts gave their full affirmation and opinion on the analysis data of the output products. Can get the expert's approval, gave great encouragement to our research, the set of equipment, low operating costs, high efficiency, the advantages are significantly higher than other domestic similar products.

The comprehensive utilization of the phosphogypsum waste accumulated in the power plant sulfur gypsum and phosphate fertilizer plants will surely usher in a bright future.

Some members of the plaster expert group:

Yue Wenhai:

Yue Wenhai is a deputy chairman of the Professional Committee of Gypsum and Gypsum Products of the China Silicate Academy and a professor at Wuhan University of Technology. He graduated from Nanjing University in 1954 and served as a senior visiting scholar at Oklahoma State University from 1989 to 1990. He once served as Director of Materials Research and Testing Center of Wuhan University of Technology, Director of Open Research Laboratory of National Building Materials Bureau, and Director of Inorganic Non-metallic Materials Specialty Teaching Guidance Committee of National Higher Education School, enjoying special government allowances from the State Council.

Professor Wenwen Yue is a senior scholar in the field of gypsum building materials in China. Since the 1950s, it has been engaged in the research of gypsum theory and application. In the 1970s, it began to recruit graduate students. In China for the first time using modern testing methods, starting from the pure phase preparation, systematically studied the type, structure and characteristics of the gypsum dehydration phase. Preparation conditions and the formation mechanism of each phase transformation,
A method for classifying the gypsum dehydration phase was proposed, which revealed the mechanism of dehydration of dihydrate gypsum to form β-hemihydrate gypsum by nucleation-diffusion. In the study of the preparation of beta hemihydrate gypsum, it was found for the first time that the two-step method could significantly increase the strength of strength. In addition, it has made important contributions to the aging mechanism of calcined gypsum, the mechanism of action of alpha hemihydrate gypsum crystallizing agent, and the activation mechanism of anhydrite.
