Optimization of composite nucleating agent for wear-resistant Al-Si glass ceramics ZHAO Yun-cai 1 XIAO Han-ning 2 TAN Wei 2 (1. Department of Mechanical and Electrical Engineering, Yueyang Normal College, Yueyang Hunan 414003; College of Materials Science and Engineering, Hunan University, Changsha 410083, Hunan, China) 3. Conclusion 3.1 Preparation Wear-resistant glass ceramics, the use of orthogonal test method to determine the compound nucleating agent ratio of CaF2C'23 3.2 nucleating agent CaF2, CQ3 and Zr2 content of the glass phase separation, crystallization and the improvement of the wear resistance of the material are There is a greater impact on the preparation of wear-resistant glass ceramics more ideal composite nucleating agent components.
3.3 Compound nucleating agents (CaF2, Cr23, and Z2) are favorable for the dissolution of glass in the melt while reducing the interfacial energy, so that the activation energy of nucleation is reduced, so that it is easy to obtain high-performance wear-resistant glass ceramics with compact structure and fine grains.
The present invention provides a multifunctional pull faucet, comprising: a faucet body, a drawing part is provided at the water outlet port thereof, and the drawing part is connected to a main channel, wherein at least three are provided in the faucet body A branch channel, and the three branch channels are all connected to the main channel. A multifunctional pull faucet provided by the present invention, wherein the hot water channel, the cold water channel and the water purification channel (pure water channel) are all connected to the main channel , And the main channel is connected with the drawing part on the main body of the faucet, so that the drawing part can obtain the water quality (hot water, cold water, purified water or pure water) required by different users, thereby improving the user experience, and , By integrating the hot water channel, cold water channel and pure water channel (pure water channel) into the main channel, the internal structure of the faucet is simplified, and the production cost of the faucet is reduced.
