Full text of the announcement: The company has recently obtained the invention patent certificate issued by the State Intellectual Property Office. The details are as follows: Invention name: A method for measuring the wear ratio of polycrystalline diamond composite sheets Patent No.: ZL201010030197.5 Patent Type: Invention Patent Application Date: 2010 Patent period of January 18 : 20 years (calculated from the filing date) This invention patent provides a new detection method for the wear resistance of polycrystalline diamond composite sheets. The acquisition of this patent will not have a major impact on the company's recent production and operation, but it will be beneficial to the company's new product research and development, which will help protect the company's intellectual property rights and enhance the company's core competitiveness. Special announcement. The impact of the Board of Directors of Henan Sifangda Superhard Materials Co., Ltd. on Sifangda on November 22, 2011 , the company stated that this invention provides a new detection method for the wear resistance of polycrystalline diamond compact (PDC). . The acquisition of this patent will not have a major impact on the company's recent production and operation, but it will be beneficial to the company's new product research and development, which will help protect the company's intellectual property rights and enhance the company's core competitiveness. Although the company said that it will not have a major impact on the recent production and operation, but the stock price of Sifangda was stimulated by the news yesterday to close the daily limit. The specification of the patent obtained by the reporter describes a method for measuring the wear ratio of the polycrystalline diamond composite sheet, fixing the polycrystalline diamond composite sheet to the lathe tool holder, and cutting the concrete block with the polycrystalline diamond composite sheet. Calculate the loss volume of the polycrystalline diamond composite sheet and the concrete block. The ratio of the loss volume of the concrete block to the loss volume of the polycrystalline diamond composite sheet is defined as the wear ratio of the polycrystalline diamond composite sheet. The concrete block is composed of a certain proportion of cement, sand and water. Stir well, pour into the mold, vibrate and compact, solidify and maintain for several days. According to the mass percentage, the cement in the concrete block material accounts for 10-50% of the total weight of the raw materials, and the sandstone accounts for 20-60% of the total weight of the raw materials. Water accounts for 5-30% of the total weight of raw materials. It is worth mentioning that the specification of the patent also describes that the method has small measurement error and can accurately reflect the wear resistance of the polycrystalline diamond composite sheet PDC. Obviously, this technology will help the development of PDC. It is understood that Sifangda's main business is a composite superhard material manufacturer, and the main products of composite superhard materials include polycrystalline diamond compact (PDC), polycrystalline cubic boron nitride (PCBN) composite and polycrystalline diamond (PCD). ) Drawing die blanks, etc. With the support of advanced production technology and unique material formula, the technical performance of the company's composite super-hard materials is close to or reach the level of international similar products, but it still has the leading international competitors in the high-end products such as PDC for oil/gas. A certain gap.

Sifangda announced yesterday that the company has recently obtained the invention patent certificate issued by the State Intellectual Property Office. The invention name is a measurement method for the wear ratio of polycrystalline diamond composite sheets. The patent term is 20 years. In the afternoon, Sifangda's share price rose sharply and eventually closed at the daily limit.
