High decibel noise in industrial and manufacturing environments not only reduces productivity, but also threatens workers' health. Studies show that exposure to high noise levels can lead to stress and fatigue, which can lead to injury or hearing loss. Work environment polluted by high intensity noise (such as heavy engineering machinery and metal processing plant operating noise and other troubled voice) can be installed through the denali melamine foam sound-absorbing board method to make noise to acceptable levels. The Yadina mylamine foam wall panel and refraction panel can reduce and control the noise and reverberation in factories, assembly plants and other industrial occasions by blocking and filtering sound waves. Yadina melamine foam can before industrial noise became a difficult problem to solve in intangible, has helped thousands of companies to protect the health of its employees and saves expensive insurance claims. Yadina production of melamine foam resistance to high temperature (240 ℃ high temperature peak) and flame retardant B1 level (flame retardant), sound attenuation coefficient, the NRC = 0.95), so it can provide efficient solutions for industrial noise reduction. After cutting, the Yadina melamine foam board can be used directly in the ceiling and wall of the workshop to achieve the effect of sound absorption. The Yadina mylamine foam is cut and cut, it can be processed into the insulation layer of the pipe, and it has excellent anti-noise insulation for hot water canisters, air-conditioned ventilation ducts, gas pipelines and hot air ducts.
