    1、 Product introduction



     

    Jianyuan glass magnesium composite air duct is a new type of high-tech composite plate, It is a new generation of energy-saving and environmental protection green products with light weight, high strength, non combustion, sound insulation, heat insulation, moisture resistance, water resistance, long service life, etc.


    Glass magnesium composite air duct is mainly used in construction, decoration, fire protection and other fields, especially suitable for the decoration of crowded places such as restaurants, hotels, shopping malls, basement, civil air defense and mine and other humid environment projects. Glass magnesium fire-proof board is a replacement product of various plywood, density board, particleboard, gypsum board, etc., which is the green product recommended by the National Decoration Association Color environmental protection building materials. The glass magnesium composite air duct has been tested by the national building materials testing center and the national quality supervision and Testing Center for fixed fire extinguishing systems and fire-resistant components, and its physical properties meet the technical requirements of qualified products in JC / t646-2006 standard, and the combustion performance reaches gb8624a.

    4、 Product features

    U ultra high strength performance: Jianyuan brand glass magnesium air duct has high strength, flexural strength is greater than 1.8MPa, can withstand 3000pa wind pressure, can meet the use of high, medium and low pressure air system.

    Unique moisture-proof performance: Jianyuan glass magnesium composite air duct has high water resistance, no rust and corrosion in humid environment. Even if it is soaked in moisture, it can still keep its original shape, and its moisture resistance strength is above 97%.

    U green environmental protection, clean air: as a new type of green and environmental protection building materials, Jianyuan brand glass magnesium composite air duct has taken effective environmental protection measures from the aspects of raw materials, process formula, energy consumption and emission in the production process, product recovery, etc. no matter in the process of production, production, installation or use, the air duct does not produce substances that pollute the environment. Through the test, even when the air duct is burning, the smoke produced by it does not contain toxic substances and is harmless to human body. At the same time, it has no rust, no mildew, no dust, no reproduction of bacteria and bacteria, no dust and fiber, no odor, no granular, gaseous pollutants and biological aerogel, which can improve the indoor air quality

    Excellent fire protection performance: Jianyuan brand glass magnesium air duct is composed of non combustible inorganic materials and non combustible thermal insulation materials by high-tech technology, and is determined to be A-class non combustible material through the inspection of national fire protection construction quality supervision and inspection center. The special adhesive and accessories of Jianyuan brand glass magnesium air duct are all class a non combustible materials.

    U Low air leakage rate, improve the efficiency of air transportation: Jianyuan brand glass magnesium composite air duct is made of imported adhesive structure without flange connection, which greatly improves the airtightness of air duct. Compared with iron sheet air duct, it reduces the air leakage rate of bite and flange, reduces the air leakage rate of air duct, and improves the efficiency of air transportation. The air leakage rate of Jianyuan brand glass magnesium composite air duct is far lower than that of iron Air leakage rate of skin duct.

    U good thermal insulation performance, reduce heat conduction energy consumption: Jianyuan brand glass magnesium composite air duct is directly composite with thermal insulation materials, no secondary insulation is required, the air duct thermal conductivity is small, the insulation performance is excellent, and the heat conduction loss in the process of cold and hot air transportation is reduced.

    U small wind resistance, reduce friction loss: Jianyuan brand glass magnesium composite air duct adopts mechanized production, with smooth and smooth surface, small friction coefficient, low wind resistance and minimal absolute surface roughness of air duct.

    Excellent sealing performance: Jianyuan thermal insulation composite ventilation pipe is made of adhesive and hook, without other material link, which greatly improves the sealing performance, reduces the air leakage rate and greatly improves the air transmission rate.

    U long service life, saving investment: Jianyuan brand glass magnesium composite duct product design structure is reasonable, reliable performance, stable quality, service life more than 30 years, saving multiple cost investment for customers
