Coating classification: damping coating

Core tip: damping coating is a kind of coating which can absorb mechanical work, reduce vibration and noise Damping coating is one of the important materials for vibration and noise control of aviation, ship, automobile and other mechanical equipment at home and abroad Because the inherent damping and damping performance of metal structure is very low, it is necessary to improve the damping and damping performance of metal structure by using damping and damping system with excellent performance and reasonable structure to ensure the smooth operation of equipment or device and reduce noise pollution Damping coating can transform the mechanical energy of vibration into heat energy or other forms of energy consumption, thus improving the vibration attenuation rate In addition, damping coating can reduce vibration and pressure Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: damping paint is able to absorb mechanical power, reduce vibration, reduce noise paint Damping coating is one of the important materials for vibration and noise control of aviation, ship, automobile and other mechanical equipment at home and abroad Because the inherent damping and damping performance of metal structure is very low, it is necessary to improve the damping and damping performance of metal structure by using damping and damping system with excellent performance and reasonable structure to ensure the smooth operation of equipment or device and reduce noise pollution Damping coating can transform the mechanical energy of vibration into heat energy or other forms of energy consumption, thus improving the vibration attenuation rate In addition, damping coating not only has the functions of vibration reduction and noise reduction, but also has the functions of heat insulation, oil resistance, water resistance, corrosion resistance and sealing Damping coating is made up of polymer resin and some fillers and auxiliary materials It is a special coating which can be applied on the surface of various metal plate structures According to the different mechanism of damping coating, damping coating can be divided into free damping structure and constrained damping structure The free damping structure pastes a certain thickness of viscoelastic damping material on the surface of the base plate When the base plate produces bending vibration, the damping layer vibrates together with the basic layer, and generates tension compression deformation inside the damping layer, which consumes energy, thus plays a role of vibration reduction and noise reduction Representative free damping coatings such as 3101 multifunctional water-based damping coatings A high modulus elastic layer is pasted on the outer surface of the damping layer of the constrained damping structure When the damping layer produces bending vibration along with the basic structure layer, which causes the damping layer to produce tension compression deformation, the elastic layer will play a role of constraint and produce shear deformation, thus consuming more energy The representative constrained damping coating is 3109 The damping property of damping coating is closely related to temperature and frequency Low temperature is equivalent to high frequency, high temperature is equivalent to low frequency The selection of damping coating varies with working frequency and temperature, such as wide temperature range damping coating, low temperature range damping coating, high temperature range damping coating, etc At present, damping coating mainly covers the plate-shaped shell of vibration, such as the shell of spacecraft, the shell of aircraft, the shell of automobile, the chassis and the outer cover of vibration machinery, etc., in order to suppress the transmission of vibration and noise Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
