On January 14th, with the support of the provincial party committee, the provincial government, and the provincial quality supervision bureau, the Jixi National Graphite Quality Inspection and Testing Center was officially completed. Alongside this milestone, the Provincial Graphite Product Standardization Technical Committee—composed of over 30 academicians, experts, and professors—was also officially established. Vice Mayor Lan Zhizhen attended the press conference held at the provincial newspaper building on the same day and delivered a speech emphasizing the importance of high-quality graphite development for regional and national growth.
It is reported that Jixi has long maintained a strong technical advantage in graphite product inspection and testing. Since 1998, it has been responsible for the supervision and inspection of graphite products. To better support the development of the national graphite industry, the State Administration of Market Regulation officially approved the establishment of the National Graphite Product Quality Supervision and Inspection Center at the end of 2011. This center now serves as a key platform for quality testing, technical services, and innovation within the national graphite new materials sector, contributing to the healthy and rapid development of the industry.
In accordance with the Heilongjiang Provincial Standardization Regulations, Jixi has actively leveraged its quality supervision functions. In July 2013, the Provincial Quality Supervision Bureau officially approved the establishment of the Provincial Graphite Product Standardization Technical Committee. The committee has since been working diligently on developing national and industry standards, aiming to enhance its influence in both national and international standardization activities.
At the joint press conference organized by the provincial government and the quality supervision department, Han Yufeng, the newly elected director of the Provincial Graphite Product Standardization Technical Committee, Chairman of the National Graphite Industry Technology Innovation Strategy Alliance, and Chairman of Aoyu Graphite Group, made a statement and gave interviews to major national and provincial media outlets. His remarks highlighted the significance of standardization and collaboration in driving the sustainable development of the graphite industry.
Sds Drill Bits
SDS Plus and SDS Max drill bits can be used for drilling operations in concrete, reinforced concrete, granite and similar materials. SDS-Plus has a drilling diameter of 4mm to 32mm and a drilling depth of 110mm to 1000mm; SDS-Max has a drilling diameter of 12mm to 52mm and a drilling depth of up to 1200mm.
SDS Drill Bits are available with two (properly shaped integral straight edges), three (star arrangement) or four (integral cross arrangement) inserts, made of cemented carbide. They are deeply embedded in the steel head with industrial solder and are characterized by a high degree of mechanical and heat resistance.
SDS Plus and SDS Max Bits should not only be selected based on the diameter of the drilled hole, but also their depth standard. Both of these measures are necessary to maximize productivity.
