Zou Wenjun: Increase technological innovation and target emerging application fields

The market application of ultra-fine-grained products is wide and large, but the production capacity of domestic enterprises is limited, far from meeting the requirements. There are mainly products in these aspects: one is fluid polishing products, which are rarely involved in domestic manufacturers, but are widely used in the market; the applications of coated abrasive-attached materials such as nano-diamond micro-powder and antimony oxide are also widely used; Corundum includes alumina, which is also very large. There is also a silica sol product (silica), which is only a few tens of tons in a single company in Xuzhou. The current situation in the country is that the products that the market needs cannot be produced, and the market does not need a large surplus. For example, the range of zirconium dioxide zero micron, such as 0.08-0.03, is not available in China. There are manufacturers in the country to produce, but can not guarantee mass production, supply can not keep up, said that a few micrometers is actually a few points. For example, the ceramic accessories on the mobile phone need to be polished with diamond coated abrasives, which is currently vacant; the touch screen on the mobile phone is a high-strength glass, which is actually milled with zirconia; one is sapphire, which is ultra-thin, both Grinding and throwing, a lot of vacancies. Pyramid products are used to grind aluminum alloy casings for tablets. The polished film of the film back-base diamond did not pass the test at Foxconn.
In short, in the field of grinding and polishing, precision polishing, there are still many market vacancies urgently needed in the market, all of which are occupied by foreign products. Therefore, during the 13th Five-Year Plan period, the entire industry needs to intensify its technological innovation, aiming at emerging application fields and producing high-value-added products that are urgently needed in the production market.

The heat conversion rate of it is over 98% so the temperature rises fast. It can reach the set temperature in short time after being charged with electricity. Moreover, when the set temperature is reached, it will cut off the electricity automatically.
The temperature of the screen can maintain 80 degree so it is very safe for the customers. Besides,it is safe to children and pets.(Different sizes correspond to different power)
