Manufacturer of soundproof and damping felt

Damping soundproof felt manufacturer Damping soundproof felt (foreign name: damping) is a roll or sheet type soundproof material mainly composed of EPDM rubber, which has the characteristics of light weight, ultra-thin, softness, and high tensile strength. Damping soundproofing felt is suitable for soundproofing treatment of drainage pipes, and can be bent to fit the shape of the pipe. During construction, only cutting tools and glue are needed to complete the installation. It can be used in conjunction with gypsum board for wall and ceiling sound insulation [2], meeting the requirement of indoor background noise ≤ 30 decibels in projects such as' zero carbon buildings' in Xiong'an New Area [1]. The main application scenarios include residential buildings, hotels, hospitals, and other places. Damping refers to the characteristic of any vibration system experiencing a gradual decrease in vibration amplitude due to external forces and/or inherent reasons of the system, as well as the quantitative characterization of this characteristic. Soundproofing felt material is lightweight, ultra-thin, soft, and has high tensile strength. It has a black finish and is packaged in rolls; Soundproofing felt is made of high-purity fine iron powder as raw material, and applies shock absorption and soundproofing technology to develop soundproofing materials for floors, walls, and pipelines. It has 20 years of application experience in Japan. It can effectively isolate external noise and create a safe, quiet, and comfortable environment. Soundproofing materials are mainly divided into two categories: rolls and sheets, with nine major characteristics. The high proportion of 90% iron powder in sound insulation materials effectively increases their surface density, which is one of the important indicators used to measure the success or failure of sound insulation materials. As the surface density increases, the material becomes heavier, and the sound insulation effect is naturally well guaranteed. With its very ideal surface density, sound insulation materials,

The manufacturer of damping soundproof felt easily achieved a single weight isolation volume of over 20 decibels, while the single weight isolation volume of sheet products has exceeded 30 decibels. The model of thin soundproofing material is only 0.8 millimeters, which is only the thickness of three business cards. The soundproofing effect of the. 8mm product far surpasses traditional walls that are hundreds of times thicker than it. Thinning the product also saves space, effectively improving the utilization of space and creating greater benefits in the same area. Through rigorous experiments, it has been proven that after 72 hours of immersion in water, there is no deformation, and the use effect of the ultra quiet fragrance sound insulation material can still be guaranteed to be as good as before. flame retardant

Damping and soundproof felt manufacturers have conducted tests on flame retardancy according to international standards. The combustibility of Super Shizuka is classified as Class B except for non combustible stones, and its smoke toxicity is also a very important indicator in building materials. 1. Good waterproof effect, which can achieve immersion in water without water seepage and without mold growth; 2. High temperature resistance, without softening, deformation, or dripping when heated; 3. The thermal conductivity coefficient is small, and the thermal conductivity coefficient of polyurethane tile shell is low in insulation materials, which can reduce the heat loss of the material to a minimum; 4. Good flame-retardant property. The good flame-retardant property of polyurethane tile depends on the phosphorus containing flame retardant, which is a kind of phosphide that can agglomerate. When polyurethane foam burns, it can decompose into a product that is not easy to burn. Generally, 1.5% phosphorus is added to foam to obtain the flame-retardant effect of jia; 5. Low price, which may be a concern for people. With good performance and low price, it is difficult to achieve. This type of pipe shell is mainly processed from environmentally friendly and pollution-free polyurethane, and is one of the trusted insulation materials. The company adheres to the concept of "equal price for quality, equal quality for price; meeting the needs of customers, doing what customers think; honest management, people-oriented", insisting on making good products, insisting on making high-quality, low-priced products, and insisting on making products that satisfy customers.
