Otsu mud, a heavy-pounded brand of silican moss built by beijing daejin new materials, inc. Beijing daejin new silicates ltd., known as otsu shares, introduced japanese silican slur products and technologies back to japan in 2003 and embarked on an autonomous research and development tour of silina. In order to improve/enhance the quality of products, firms have not only imported modern equipment from abroad, set up multiple production lines, but also established large production workshops. In the production process, otsuki has always adhered to a professional production spirit, with layers of pedestals and human testing to ensure that the quality of the product is not insensitive. In order to bring the series of products into the national market, it has formed its own team and has set up brand stores in many cities to build a complete marketing network. As a result of several efforts, otshin's shares were listed in 2011 as a few new three-board companies in the silicate mud industry. Otsu shareholding is prominent in the field of green eco-walls, thanks to its strong brand strength. According to statistics, it has acquired dozens of patented technologies and has established long-standing cooperation with well-known institutions for research of building materials, such as the general institute for scientific research, the laboratory for priority research on green and environmentally sound building materials, and has facilitated cooperation with inspection agencies, such as the centre for technical supervision of building materials and the centre for monitoring and inspection of construction materials. Today, it is also continuing to improve its own production processes and technical equipment, paving the way for bulk production of r&d under the flag。
