The State Council of the State-owned Assets Supervision and Administration Commission recently released an official notice regarding the China Petroleum and Chemical Industry Association's request to establish a Grease Professional Committee. This move marks a significant step in the formalization and coordination of the grease industry within the broader petroleum and chemical sector.
Grease, as a critical component of petroleum products, plays a vital role in various sectors, including industrial, civil, defense, and aerospace applications. In 2005, China produced approximately 270,000 tons of grease annually, accounting for nearly 20% of global output. Its widespread use underscores its importance in both economic and technological development.
In its application, the China Petroleum and Chemical Industry Association explained that the grease industry organization was initially established in 1985 with the approval of the Ministry of Civil Affairs. It was affiliated with the Petroleum Refinery Committee of the China Petroleum Institute. The association included state-owned, local, and private grease companies, research institutions, military research units, and other related organizations, totaling 38 member institutions at the time. In 1987, it was renamed the Grease Association.
Over the years, the association has contributed significantly to the growth and development of the grease industry. However, due to changes in regulations, such as Decree No. 23 issued by the Ministry of Civil Affairs in 2001, which prohibited branch organizations from establishing lower-level entities, the structure of the association became outdated. Additionally, the narrow scope of the industry made it unsuitable to function as a national-level association, affecting its operational efficiency and coordination.
To address these challenges and ensure more effective management and service, the association has now applied to become a specialized committee under the China Petroleum and Chemical Industry Association. The association’s Fourth Session of the Council approved this application, and it is planned to establish the "China Petroleum and Chemical Industry Association Grease Specialty Committee" based on the existing Grease Association. This restructuring aims to enhance the industry's standardization, improve service quality, and better support the development of the grease sector in China.
Sapphire Crystal
Sapphire glass
Sapphire crystal has a crystalline rather than a glass-like structure. Sapphire has a Mohs hardness of 9, which is the third hardest of all transparent materials after Moissanite and diamond, so it is particularly valuable in this application because of its scratch resistance. Sapphire crystal is a high-purity synthetic sapphire (single crystal) made of fused alumina. The chemical formula is Al2O3, and the sapphire crystal is corundum.
Compared with traditional quartz glass or mineral glass, sapphire glass is slightly less sensitive to impact, and has a very high light transmittance and refractive index.
The physical properties of synthetic sapphire crystals:
Hexagonal crystal structure
Density: about 4 g / cm³
Melting point: +2050℃
Thermal conductivity at 25℃: 42 W/(m·K)
Compressive strength at 24°C: 2GPa
Tensile strength at 24°C: 186.4 MPa
100% acid resistance
