In the extrusion mode, the movement direction of the magnetic pole plate is the same as that of the magnetic field. The two magnetic poles move relatively close or far away. The corresponding magnetorheological fluid flows toward the center or around under the pressure of the magnetic pole plate. The magnetic field direction is perpendicular to the flow direction of the magnetorheological fluid. When the pole plate is in relative motion, the field strength will change to control the damping force. This mode is suitable for vibration control with small vibration peak value.
Pneumatic butterfly valves are mainly used in various means of transportation and equipment. The adhesiveness is a difficult problem in the production process of pneumatic butterfly valves, and it is precisely because of the unique adhesiveness that it has a better valve and buffer function. The test shows that various components and processes in the cyanide electroplating copper zinc alloy solution have influence on the adhesion. After many tests, the best process is finally determined. The adhesion conforms to the national standard and greatly exceeds the established national standard. Brother Pneumatic Butterfly Valve Technology Co., Ltd. has adopted this process and is at an advanced level in the industry. Of course, adhesion is not the only criterion to judge whether a material has valve characteristics,
This composite material has a certain damping effect, which is not conducive to heat generation and has hysteresis, because deformation will occur in the process of the valve, and the mechanical energy generated by friction during deformation will be converted into heat energy. Adding some softeners in can improve the limitation of no heat generation.
It not only has strong adhesive property, but also has good corrosion resistance, which shows its wide use. For the harmful gas generated during manufacturing will lead to formaldehyde exceeding the standard, we use 2M-41 cyanidation copper plating fog inhibitor to inhibit the emission of harmful gas, which responds to the national air pollution control policy, with good results.
