Piping insulation materials used mainly by sound-absorbing sponge EPDM rubber and composition, the material is 5 meters long, one meter wide, thick roll of 20mm. Special design of the material, can be a good noise suppression pipeline to the outside world radiation. Acoustic principles: sound absorbing material used in the outer compartment of the design. Using sound-absorbing foam lining, the main role is to prevent the spread to the outer pipe wall vibration insulation materials, can ensure sound insulation layer insulation material. While the outer layer of insulation material with a cavity formed in the conduit wall, the radiation noise outwardly through the conduit wall, the outer insulation material through the cavity after reflection absorbing sponge. The outer layer of insulation material, using a special green rubber added minerals produced, with good sound insulation properties. Insulation materials can be well isolated from the water flow from the impact of low frequency noise deadening insulation single volume at 25 decibels, the insulation materials used in pipes, can be isolated from 16-18 decibels of noise. Ultra-thin insulation materials and simple construction, while in the construction process, no itching, does not pollute the environment. While taking into account the design of the waterproof material issue, the material can be used in any environment. Facilitate reduction of insulation materials, while the insulation materials have good plasticity, can be wrapped in different pipes. Can be solved sewer bring you unhappiness.
