| Specifications:Product name, product specifications Product model weighted septal volume (dB)Wei Ke 1.2 soundproof felt 1000*10000*1.2mm Vinco-1.2 23dBWei Ke 2 soundproof felt 1000*10000*2.0mm Vinco-2.0 29dBWei Ke 3 soundproof felt 1000*5000*3.0mm Vinco-3.0 32dBOther specifications, models can be customized according to requirementsStructure damping soundproof felt:Deadening felt components generally includes three parts: substrate, fillers and additives.The sound insulation mat, rubber asphalt, three yuan, polyvinyl chloride, chlorinated polyethylene, different manufacturer will according to the different substrate selection of technical scheme for their. Sound insulation mat will add filler in the production process, commonly used fillers include metal powder, quartz powder, coarse whiting, the purpose is to increase the deadening felt density, so as to increase the volume of sound insulation effect. Filler added to the proportional control, otherwise it will lead to loss of elasticity and toughness deadening felt. In order to enhance the deadening felt elasticity, viscosity, toughness, fire resistance and tear strength and other physical properties, additives, but also to join the production process. AIDS will not only affect the physical properties of sound insulation mat, will have an important i***ct on environmental performance, because some additives are toxic.Wei Ke deadening felt is according to this principle, the introduction of foreign advanced technology and equipment, the best anti-aging corrosion tasteless EPDM rubber and a dozen organic minerals formed according to a certain proportion of refined, product is the black, green no smell, very good inhibitory effect on the low and high frequency sounds have, can effectively inhibit various vibration propagation. The material thickness ranging from 2.0mm, testing by the National Building Materials Bureau, weighted sound insulation amount Rw 27dB respectively, the flexibility is also very good, can be bent, arbitrary cut the ribbon, the construction is |
