What are the properties of formaldehyde-free glass fiber muffler?  It is estimated that many people have almost understood it, and have even begun to study the production and installation of formaldehyde-free glass fiber muffler, whether it has muffler, environmental protection properties, fire rating can reach GRADE A and other details, which means that you have A certain understanding of it, but not necessarily comprehensive.  Here, according to the needs of users, the performance of the deadened the noise of fiberglass duct do a simple summary, wish I could help you, to the rise in recent years, a new type of air conditioning and ventilation duct have a deeper understanding, so as to make better use of formaldehyde-free deadened the noise of fiberglass duct, as soon as possible to complete the construction design and installation of air conditioning and ventilation system.  

What are the properties of formaldehyde-free glass fiber muffler?  As a new type of air conditioning ventilation pipe, its performance can be summarized with eight words "sound absorption and noise reduction, heat preservation and heat insulation", which is also the performance of glass wool, because the material of formaldehyde-free glass fiber muffling duct is formaldehyde-free glass wool plate, this plate has a good sound absorption and noise reduction, energy saving and heat preservation.  And formaldehyde-free glass fiber muffler air duct light quality, high density, high strength, is light and high strength air conditioning ventilation duct, can greatly reduce the load of the building.  Compared with the traditional iron duct, it is more suitable for the design needs of modern buildings and keeps the aesthetics of buildings.  

There are many performance advantages of formaldehyde-free glass fiber muffler air duct. The advantages and performance of the above mentioned can reach fire grade A, as well as small air leakage, simple production and installation, etc., all depend on the middle layer material of this air duct and the sealing glue and tape.  Formaldehyde-free deadened the noise of fiberglass duct middle tier of the density of 80 kg/m3 formaldehyde-free green glass wool board, its inner layer coated with nano polymer coating, has a good sound-absorbing and antibacterial moisture-proof performance, many large buildings, such as shopping center, cinema, hotel, or even deadened the noise of apartment villa will suggest using formaldehyde-free glass fiber duct,  It can not only absorb sound and reduce noise, but also be formaldehyde-free and environmentally friendly, and keep indoor air clean. These are the embodiment of the good performance of glass fiber muffler.  

Glass fiber muffler air duct also has two kinds, one is ordinary glass fiber muffler air duct, with traditional yellow glass wool plate;  The other is the formaldehyde-free fiberglass muffler we mentioned. The color is white glass wool plate.  Formaldehyde-free glass wool plate binder is formaldehyde-free, and fiber is long and thin, almost no dust generation, good resilience, and the general plate binder is formaldehyde, not up to the standard of zero formaldehyde.  Now on the market, it is the environmental performance of formaldehyde-free glass fiber muffler, as well as muffler, heat preservation and other properties that are the focus of users.
