First, all kinds of air duct introduction
Galvanized steel pipe: one of the most used on the market, the earliest history of the ventilation pipe, the use of galvanized thin steel plate processing and production, suitable for the transport of general air with low humidity, no insulation and noise reduction functions, production and installation period is long. However, galvanized steel duct is a traditional product with a wide range of uses and places of use, and its advantages and disadvantages have long been understood and recognized by the majority of users. However, due to the particularity of its strength and structure, it can not be completely replaced.
Inorganic FRP air duct: a new type of air duct, the use of glass fiber reinforced inorganic material processing, fire resistance, corrosion resistance, large weight, hardness but fragile, will be affected by the weight of easy deformation and fracture, without insulation and noise reduction functions, the production and installation cycle is very long. In recent years, with the passage of time, people gradually understand some shortcomings of inorganic FRP air ducts, so that the market share of inorganic FRP air ducts is gradually shrinking.
MX Fabric air duct: MultiXair (MX) Fabric air duct is a flexible outlet end system made of special flame retardant fibers that replaces air ducts, air valves, tuyere or diffusers, insulation materials, etc. Also known as MX fabric duct system. With surface air, large air volume, no blowing sense; The whole air supply is evenly distributed; Anti-condensation; Easy to clean and maintain, healthy and environmental protection; Beautiful high-grade, diverse colors, outstanding personalization; Light weight; System operation quiet, improve the quality of the environment; Installation is simple and flexible, cost-effective advantages.
Second, all kinds of air duct performance comparison
1, noise reduction performance comparison
Galvanized steel sheet air pipe: no noise reduction performance, its own vibration will produce sound, must be installed muffler.
Inorganic fiberglass duct: no noise reduction performance, sound insulation performance is better than galvanized thin steel duct, must be equipped with muffler.
MX fabric air duct: its pipe wall is flexible fiber fabric, itself is a bad conductor and absorber of sound, it does not produce sound, it can also absorb equipment noise to a certain extent, with the extension of the pipeline, the effect is more obvious, can eliminate the special muffler.
2, insulation performance comparison
Galvanized sheet steel duct: large thermal conductivity, no thermal insulation performance, must be added insulation layer and protective layer.
Inorganic fiberglass duct: large thermal conductivity, no insulation performance.
MX fabric duct: The purpose of duct insulation is to prevent energy loss and condensation on the surface of the duct. Using the permeability of the fiber fabric itself, the cold air layer is formed on the surface of the air duct, so that there is no temperature difference between the inside and outside of the pipe wall, so that it will not condense, and the same effect is achieved by using a large number of insulation materials in the ordinary air duct.
3. Strength comparison
Galvanized steel sheet air duct: high strength, strong static pressure resistance, in the section size must be strengthened according to the provisions.
Inorganic fiberglass duct: high strength, but more fragile, because it is heavy, not easy to carry, vulnerable to collision resulting in cracking and damage.
MX fabric duct: Flexible material, but good toughness. Withstand pressure greater than 3000Pa.
4, moisture-proof performance comparison
Galvanized sheet steel air duct: susceptible to moisture corrosion and rust, which is more serious when conveying air with large moisture content.
Inorganic FRP air duct: limited by the proportion of raw materials, its moisture resistance stability is poor.
MX fabric air duct: Because of the cold air layer on the surface, there is no condensation.
5. Comparison of construction and installation
Galvanized sheet steel air duct: the pipe is heavy, the production and installation cycle is long, and the pipe size and direction are time-consuming. The thermal insulation layer is installed on site after the air duct is installed, which is a tedious process.
Inorganic FRP air duct: The pipe is heavy, not easy to carry, high strength, but relatively fragile, vulnerable to collision resulting in cracking and damage. The production and installation cycle is long, and the change of pipe size and direction is time-consuming. Noise reduction and heat preservation with galvanized sheet steel.
MX fabric air duct: Easy to install, high degree of systematization, simply hang and connect on site. The installation time can be reduced to one-fifth of the traditional way.
MX Misch has accumulated experience in the design and implementation of various types of fabric air duct projects at home and abroad, and has summarized several sets of installation methods for different places. For more information, call 400-836-9929
