Since 2018, Chengzhi Yonghua has been invited to join the National Technical Committee for Standardization of Semiconductor Equipment and Materials (SAC/TC203) and has been involved in the review of national standards in the industry. In just over a year, Chengzhi Yonghua, with its important mission, has completed its own transformation into a Huamei brand.

According to the "Management Measures for Group Standards of Shijiazhuang Standardization Association", on December 24, 2019, Shijiazhuang Standardization Association approved the release of the "Differential Scanning Calorimetry Method for Determining the Melting Point of Liquid Crystal Monomers" (SBX 026-2019), "Direct Current Voltage Method for Determining the Resistance of Liquid Crystal Monomers Induced by Isothermal Reaction" (SBX 027-2019), and "TFT Mixed Liquid Crystal Density Testing Method" (SBX 028-2019) developed by our company, which will be implemented from February 1, 2020. This is hereby announced.

The formulation of standards is an important step in product quality control. Standards can provide important basis for product inspection and quality control, which is conducive to strictly controlling the content of each component, ensuring the quality of LCD products, and promoting the development of the LCD industry chain. It has important economic significance and scientific value.

Our company will continue to be committed to the research of testing methods for liquid crystal monomers and liquid crystal mixtures, actively carry out standardization construction work, do a good job in technical layout and standard layout, create cutting-edge advantages in new materials and technologies, strive to play a leading role in standardization construction in Hebei Province and even the country, and demonstrate our responsibility in the field of liquid crystal materials.
