Industry elites attend exchange meetings
From June 15th to 18th, 2020, the 'National Gypsum based Mortar Production and Application Technology Exchange Conference' organized by Qihang Media was grandly held at the Zheping Hotel in Zhengzhou. Representatives from over 600 gypsum upstream and downstream production enterprises from all over the country, as well as experts and professors from many well-known universities, totaling more than 1200 people, attended this grand event. The conference mainly focused on gypsum calcination technology, gypsum formula research, common problems in gypsum plastering and self flow, and the next development trend of the gypsum industry. The conference was packed with applause and the atmosphere was very lively! Many attendees expressed that they had gained a lot and that this trip was not in vain.

There were no empty seats at the exchange meeting

Mr. Tao Tao, General Manager of Yunnan Zhuangan Technology Co., Ltd
The conference had a total of 42 agenda items, with one of the biggest highlights being a report on the production and application of phosphogypsum. Professor Sun Zhenping from Tongji University in Shanghai exchanged views with everyone on the development of phosphogypsum hydraulic composite cementitious materials and their derivative applications in pre mixed mortar; Professor Ma Baoguo from Wuhan University of Technology shared his research on the design, preparation, and application technology of high-performance phosphorus based cementitious materials; Mr. Wang Liangjie, General Manager of Hubei Xinyangfeng New Building Materials Technology Co., Ltd., reported on the topic of 'Introduction to Xinyangfeng Phosphogypsum Purification and Refining Process and the Whole Industry Chain'; Mr. Tao Tao, the general manager of Yunnan Zhuangan Technology Co., Ltd., gave a lecture on 'Advanced Technology for Harmless Treatment of High Grade Phosphogypsum by Water Washing and Calcination'. Mr. Yang Jiaguo, Technical Director of Hubei Zhimeitang Gypsum New Technology Co., Ltd., shared with industry elites the 'Harmless Treatment Process of Phosphogypsum and Its Application in Plastering and Self leveling'.

Mr. Yang Jiaguo, Technical Director, introduces five important types of phosphogypsum based plastering mortar
The report of Zhimeitang mainly introduces the impurities and harmless treatment process of phosphogypsum, five important phosphogypsum based plastering mortars, and thick layer self flowing phosphogypsum based materials. The report took 3 months and traveled over 10000 kilometers to collect data before finally being completed. The attending representatives expressed their appreciation for the rigorous scientific attitude and pragmatic and truth-seeking practical spirit of Zhimei Tang. During the intermission of the conference topic report, the organizer also interspersed numerous award-winning knowledge quizzes, and everyone actively participated and answered questions enthusiastically, pushing the academic exchange atmosphere to a climax time and time again.

The conference also carefully arranged over 100 booths for participating companies to promote their products and exchange technology. At the Zhimeitang booth, samples of the company's newly developed Xinyangfeng phosphogypsum based self leveling, Yunnan Zhuangan phosphogypsum based lightweight plastering gypsum, ultra-thin layer plastering gypsum, insulation layer plastering gypsum, as well as Zhimeitang series gypsum additives, high-quality vitrified microbeads, and other products were displayed. Representatives from various enterprises stopped to discuss and exchange information with the technical engineers of Zhimeitang on the harmless treatment technology of phosphogypsum, and to learn about the latest developments in the industry.

The machine spraying site jointly set up by Jin Yakun Building Materials and Zhimei Tang
Outside the venue, Zhimeitang and Hubei Jinyakun Building Materials Co., Ltd. jointly held a large-scale machine spraying demonstration of phosphogypsum based lightweight plastering gypsum. Representatives from enterprises who come to observe the machine spraying process and learn about the phosphorus sulfur mixed gypsum and water washed phosphogypsum processes are constantly coming. Enterprises interested in Zhimeitang products have personally taken the stage, testing spray guns, spatulas, and scrapers, all praising the excellent quality and performance of the lightweight plastering phosphogypsum on site!

Industry elites experience the spraying effect of phosphogypsum machine
This conference involves various aspects of gypsum production and application, but why has phosphogypsum attracted widespread attention and discussion? There are two reasons for this: firstly, the long-term development of the gypsum building materials industry is facing the problem of gypsum resources; Secondly, the harmless treatment process of phosphogypsum has matured.

Guests braved the rain to observe the machine spray demonstration
As is well known, although desulfurization gypsum has been recognized and widely used in the industry, the price of raw gypsum is becoming increasingly high and requires bidding for purchase; And with the continuous advancement of power plant technology, the amount of by-product desulfurization gypsum is decreasing. In the future, only mortar factories that have access to desulfurization gypsum resources can afford to use desulfurization gypsum. At present, the phosphogypsum used in the industry is a by-product of the phosphoric acid industry. China's phosphogypsum stockpile alone has exceeded 200 million tons, and it is increasing every year, making the resources particularly abundant. In addition, in recent years, large domestic phosphating enterprises have invested heavily in harmless treatment of phosphogypsum, and the effect is very significant. Harmless treated phosphogypsum has high whiteness, high strength, and is easy to construct, gradually replacing desulfurization gypsum in large quantities. Lightweight plastering gypsum produced from phosphogypsum has been widely used in Beijing, Hubei, Yunnan, Guizhou, Sichuan, Chongqing and other regions; The gypsum wall panels and gypsum mold boxes produced with phosphogypsum are also on the right track, and in the future, only phosphogypsum resources can support gypsum mortar building materials.

It can be said that phosphogypsum has never received as much attention on the stage of gypsum building materials as it does now. It is the harmless treatment process and advanced application technology that promote the virtuous cycle of phosphogypsum turning waste into treasure! Although there is still a lot of work to be done, there is no doubt that the development of phosphogypsum has ushered in spring!
