1、 Product introduction
Jianyuan glass magnesium composite fire and smoke exhaust 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 fire and smoke exhaust 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, mine and other humid environment projects. Glass magnesium fire-proof board is a replacement product of various plywood, density board, particleboard, gypsum board and other boards, which is the focus of the National Decoration Association Recommended green building materials. Glass magnesium composite fire and smoke exhaust duct has been tested by national building materials testing center, national fixed fire extinguishing system and fire-resistant component quality supervision and testing center, and its physical properties meet the technical requirements of qualified products in JC / t646-2006 standard, and its combustion performance reaches gb8624a.

4、 Product features
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 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 fire-proof smoke exhaust 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 environmental protection building materials, Jianyuan brand glass magnesium composite fire and smoke exhaust 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 production, production, installation or use process, 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 u Low air leakage rate, improve air transmission efficiency: Jianyuan brand glass magnesium composite fire smoke exhaust duct is made of imported adhesive structure, without flange connection, greatly improving the airtightness of the air duct. Compared with the iron sheet air duct, it reduces the air leakage rate of bite and flange, reduces the air leakage rate of the air duct, and improves the efficiency of air transportation The air leakage rate is far lower than that of the iron sheet air duct.
U good thermal insulation performance, reduce heat conduction energy consumption: Jianyuan brand glass magnesium composite fire smoke exhaust duct is directly composite with thermal insulation material, no need for secondary insulation, air duct thermal conductivity is small, thermal insulation performance is excellent, reduce the loss of heat conduction in the process of cold and hot air transmission. U small wind resistance, reduce friction loss: Jianyuan brand glass magnesium composite fire smoke exhaust duct adopts mechanized production, the surface is smooth and flat, the friction coefficient is small, the wind resistance is low, and the absolute surface roughness of the air duct is very small. 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. Long service life and investment saving: Jianyuan brand glass magnesium composite fire and smoke exhaust duct has reasonable design structure, reliable performance and stable quality, and its service life is more than 30 years, which can save multiple cost investment for customers
