Noise reduction plate and processing technology thereof

Abstract

The invention relates to the related field of the environmental protection technology, in particular to a noise reduction plate and a processing technology thereof. The noise reduction plate comprises a plate shell and a sound insulation and noise reduction plate, and moisture-proof centrifugal glass wool is installed in the sound insulation and noise reduction plate. According to the moisture-proof centrifugal glass wool, ceramic fibers, ethylene diamine tetraacetic acid and organic fluorocarbon resin protective agents are added on the basis of common glass wool, and the waterproof paint is sprayed on the surface of the glass wool, so that the moisture-proof centrifugal glass wool has the advantages of being high in flame retardant property, good in sound absorption effect, stable in chemical property, resistant to water and corrosion and fast to dry; the sound insulation and waterproof performance of the whole noise reduction plate is effectively improved; and a ventilation pipeline is arranged in the sound insulation and noise reduction plate and communicates with ventilation openings, and the ventilation openings formed in the front face and the back face of the plate shell are located at different horizontal heights, so that the ventilation pipeline is in a Z shape in the sound insulation and noise reduction plate, when a fan of an air conditioner rotates, noise reduction can be carried out on sound generated by the fan, and ventilation convection of air can be guaranteed.

Description

technical field [0001] The invention relates to the related field of environmental protection technology, in particular to a noise reduction board and its processing technology. Background technique [0002] With the improvement of living standards, air conditioners have entered thousands of households. For homes and small offices, the required air conditioner power is small, and wall-mounted air conditioners (1, 1.5, 2, and 2.5 horses, etc.) are generally the main ones, and the external units of the air conditioner are usually installed on the outer wall. Due to the small distance between adjacent households, the noise generated by the operation of the air conditioner's external unit is air-borne (the noise is transmitted into the household through the doors, windows and holes on the wall through the air) and structural sound (the noise is transmitted through the air-conditioning external unit). The steel bracket is transmitted to the floor or wall, and then transmitted to...

Problems solved by technology

However, a completely closed sound insulation panel will hinder air convection, thereby affecting the heat dissipation capacity. At this time, it is necessary to open some ventilation holes on the sound insulation panel to increase air convection, but increasing the ventilation holes will also allow the sound to pass through the ventilation. holes directly to the outside of the device, increasing the noise
