I. Industry Status

1. Currently, the smoke and gas ducts in the construction market mainly use cement smoke and gas ducts made with molds and manual paste, which do not meet the technical requirements specified by the national standards "JG/T194-2006" and "JC/T854-2008" issued by the Ministry of Construction and the National Development and Reform Commission. In particular, the two important indicators of the flexibility impact resistance and fire resistance limit of cement duct products cannot meet the standard requirements. When a fire occurs in the kitchen, cement ducts are prone to bursting and falling off, posing great risks to the safety of people's lives and property and public interests. Across the country, the accumulation of grease in ducts has become a fire hazard over time, and the incidence of duct fires has been increasing year by year.

2. The composite smoke duct production line is independently developed and mass-produced by Shandong Innovation Building Materials Complete Equipment Co., Ltd., and has formed a series of products suitable for various customer requirements of different scales and needs.

II. Technical Indicators of Composite Smoke Ducts

1. Water absorption rate % 17.6

2. Bending strength /MPa 13.9

3. Impact strength /(kj/㎡) 9.0

4. Vertical load /KN 121

5. Flexibility impact resistance No cracking

6. Combustion performance Non-combustible

III. Equipment Features

1. The equipment has a high degree of automation, low labor intensity, and can automatically complete slurry application, main material, fabric laying, automatic leveling, high-speed re-pressing, and large-scale equipment, achieving automated functions such as automatic board lifting, automatic cutting, and automatic board joining.

2. Can produce various specifications of boards: 1220*2440*2-40mm, 1220*3600*2-40mm, and can also be customized according to customer requirements.

3. The manufacturing of ducts is flexible and can produce various specifications of smoke and gas duct products according to different customer requirements.

4. One machine serves multiple purposes, capable of producing smoke duct boards, fireproof decorative boards, ceiling boards, and other products.

IV. Product Features

The successful development of composite smoke ducts has completely solved the technical problems that the current cement ducts cannot meet the important indicators of flexibility impact resistance and fire resistance limit as required by the national standards "Residential Kitchen and Bathroom Exhaust Duct JGT194-2006" and "Glass Fiber Reinforced Cement Exhaust Duct JCT854-2008" issued by the Ministry of Construction and the National Development and Reform Commission. This product uses new inorganic fireproof materials for mechanized production, with a fire resistance limit of over 1.5 hours. According to the latest national standard JG/T194-2006, the vertical load capacity has reached over 121KN (the national standard is ≥90KN), and the flexibility impact resistance also far exceeds the national standard. It is lightweight, crack-resistant, has strong tensile strength, and is convenient for transportation and installation. It compensates for the quality shortcomings of cement ducts, eliminates safety hazards, and completely solves the problem of smoke and odor transfer in kitchens, making it a new type of high-strength fireproof smoke and gas duct with extremely stable and safe performance.
