The polyester fiber sound-absorbing board mainly produced by our company is also known as glass wool, which is also known as polyester fiber sound-absorbing board. It is a kind of material with sound-absorbing function made from polyester fiber by hot-pressing. The polyester fiber sound-absorbing board has similar sound absorption characteristics with other porous materials, and its noise reduction coefficient is about 0.8~1.10, making it an efficient sound-absorbing body with broadband. The polyester fiber sound-absorbing board has sound-absorbing and heat-insulating properties, and the material of the board is uniform and solid, elastic, flexible, wear-resistant, impact-resistant, tear-resistant, not easy to scratch, and large in width. The polyester fiber sound-absorbing board has more than 40 colors and can be assembled into various patterns. It can make the interior shape design more flexible and effective. You can even copy art pictures on polyester sound-absorbing board through computer.

The polyester fiber sound-absorbing board has been tested by the national fire detection center for fire protection parameters, and the results show that it has good fire protection performance, and meets the requirements of the national standard GB8624B1. Generally used in engineering noise reduction: automobile engine and engineering motor seal to reduce noise. It has a good mitigation effect on high-frequency high decibel noise. It is suitable for mining operations, construction sites, motor noise reduction, large equipment operation environment and other places with strict acoustic requirements.

The Emmett calcium silicate plate produced by our company takes silicon, calcium and other materials as the main raw materials, uses the exquisite technology of rolling, pressure and densification, and undergoes autoclave curing, drying and cutting, surface polishing, etc., to produce the calcium silicate plate with the crystal structure of tobermorite (C5S6H5) as the main structure. The ceiling made of Emmett calcium silicate board has the characteristics of sag-resistant, moisture-resistant, dust-resistant and non-combustible, which effectively solves the defects of easy sagging and short service life of mineral wool board gypsum board. Emmett calcium silicate board is an ideal decoration board for permanent buildings. Partitions and ceilings are also applicable to parapets, raised floors, desktop boards, billboards, goods cabinets, kitchen and toilet wall panels, goods cabinets, fire-resistant air ducts, furniture linings, fire-resistant door linings, ships, subway engineering fire protection, etc.

Our company has passed the GB/T19001-2008 idt ISO9001:2008 quality management system certification, from product design, raw material procurement, to product manufacturing, storage and delivery, strict control, improve work quality, and ensure the quality of each piece of Emmett calcium silicate board.

Emmett calcium silicate board and cement board series products are made of siliceous materials, calcium materials, and reinforced fiber glycogen through pulping, molding, steaming, edging and other processes. Under the conditions of high temperature and high pressure, the siliceous calcium material reacts to form tobermorite (C5S6H5) crystal with extremely stable performance. Therefore, the Emmett calcium silicate plate with this crystal as the main component has the characteristics of fire prevention, moisture prevention, durability, low deformation rate, heat insulation, etc.

The mineral wool sound-absorbing board produced by the company takes mineral wool as the main raw material for production. It has sound absorption, incombustibility, heat insulation, decoration and other superior properties. It does not contain asbestos, formaldehyde and other harmful substances. The product can be recycled; Rich and colorful patterns, vivid appearance design, multiple choices, and good decoration effect; It can effectively solve the noise pollution and is an indoor ceiling decoration material that combines the advantages of many ceiling materials. It is widely used in various building ceiling and wall decoration; Such as hotels, restaurants, theatres, shopping malls, offices, studios, studios, computer rooms and industrial buildings. The product can control and adjust the reverberation time, improve the indoor sound quality, reduce noise, improve the living environment and working conditions. At the same time, the incombustible performance of the product can meet the fire protection requirements of the architectural design.

Our mineral wool board is exported to Europe, America and other parts of the world. The annual output of calcium silicate board is 6.8 million m2, the annual output of mineral wool sound-absorbing board is 4.2 million m2, and the annual output of keel is 5 million pieces
