Ps-15T high-voltage ceramic products production process and firing control

Fangwan soil: kilometers away from the plant area, the main mineral is montmorillonite is about kaolinite accounted for: A, quartz accounted for 79A, and contains feldspar, A, color is white, pink.

High-alumina bauxite: Henan Dengfeng production content above, the color is gray.

Yangshan Coal Mine Clay: It is a kilometer away from the plant area. It is a combination clay with strong plasticity. It is generally dark brown.

Hubei Luotian feldspar: mainly composed of potassium feldspar and free quartz, the color is light gray. , 6, chemical composition billet formula According to the electric porcelain craft request, we draw the local material as the main, accounting for 59A, due to the use of raw materials Fangwan soil in the formula content is more, plus the mineral is montmorillonite class, the higher the content, Improve the mechanical strength and electrical properties of ceramics. Introduce high-alumina vanadium into the blanks. The formula is shown in the table.

The glaze formulations of the proposed glaze raw materials generally require high purity, harmful impurities as little as possible in the glaze formulation was introduced when the local Bay soil, Yangshan clay, to improve glaze slurry suspension performance.

Discussion The product from the first kiln to the eighth kiln was not fully oxidized, resulting in a grayish-gray, sponge-like, and large bottom section.

From the ninth kiln to the twelfth kiln, by extending the oxidation holding time, the optical pyrometer measures the temperature in the upper half of the kiln and keeps the heat for a few hours, basically eliminating the defects of the products due to oxidation problems, but the kiln products are in the upper half. The department also appeared yellow and formed many small bubbles and orange peel-like glazes. We believe that the temperature at the start of reduction is too high. The temperature of the thermocouple instrument is the critical temperature range for peroxide, the pores are closed, and the reducing atmosphere is not easy to penetrate into the blank. Make the high-cost reduction the thirteenth kiln, learn the lessons of the above firing, adjust the reduction temperature, subject to the instrument temperature indicator, the instrument indicates that the temperature is lower, the product quality has improved significantly, the finished product rate is silicate alkali industry heat Processes and Equipment Wuhan Institute of Building Materials, etc. The first edition of the first edition of Wu Shengyu Ceramics Calculation of the blank glaze formulations and performance calculation Light Industry Press Year Guo Jing Yuan Qing Qing Daily Fine Ceramics Light Industry Press Year Month Wei Zhonghan Ceramic Decorative Materials Jiangxi Science and Technology Press Years Ceramic Technology Jiangsu Yixing Ceramic Industry School Year Month

Accelerometer Sensor

Accelerometer Sensor are widely used to monitor vibration in aerospace, automotive and manufacturing applications. Mechanical engineers often use them to diagnose problems with rotating equipment or assess the stability of structures that are subject to periodic stresses (such as monitoring the vibrations caused by trains/trucks crossing bridges, etc.) They are also often used in monitoring for condition-based maintenance, allowing engineers to examine the vibrations produced by a piece of equipment to assess its health, and monitoring the stresses sensitive equipment undergoes during transportation.

The most common method of acquiring vibration data involves connecting Accelerometer vibration sensor and configuring them into a data acquisition system that can deliver high-resolution (24-bit) vibration data at very high sample rates. Modern data acquisition systems can plot, log, filter, and analyze vibration data in real time, and allow using a variety of accelerometer types.
