The zirconia ceramic material has its own lubrication effect, so there is a great breakthrough in the fittings of the dispensing valve. The zirconia ceramic dispensing valve has a built-in cushioning and compensating elastic washer to ensure stable and good sealing performance, then the zirconia ceramic dispensing valve How should it be maintained? Nuoyi Precision Ceramics will share with you: The thickness of the ceramic dispensing valve shell exceeds the standard data requirements of GB, JB and American Standard ANSI, and the chemical elements and mechanical properties of the main material meet the specified standard requirements. First, use a wrench to unscrew the joint of the glue inlet, clean the Read more

Alumina ceramics are widely used due to their excellent properties such as high temperature resistance, strong hardness and light weight. The dielectric constant of alumina ceramics refers to a value of the degree of dielectric polarization of insulating materials under an AC electric field. The ratio of the capacitance of capacitors with the same electrode size when vacuum is used as the medium. It represents an inherent property of the material. The national standard stipulates that when the test frequency is 1MHz, the dielectric constant of the alumina ceramic structure is between 9-10. Alumina Ceramic Density The density of alumina is very small in special ceramics, only about half of Read more

Precision ceramic needle gauges are widely used because of their excellent properties such as flame retardant surface, good fire resistance, and no melting.
