1. Industry status

1. At present, the smoke exhaust and air ducts in the construction market mainly use cement smoke exhaust and air ducts made by molds and manual paste. Such products do not meet the technical requirements of 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 cement flue products, namely, the flexible impact resistance and fire resistance limit, cannot meet the standard requirements. When a fire occurs in the kitchen, the cement flue is prone to burst and fall off, posing a great hidden danger to the safety of people's lives and property and public interests. Across the country, the accumulation of oil pollution in the flue has become a fire hazard for a long time, and the flue fire has shown an increasing trend year by year.

2. The composite smoke exhaust air duct production line is independently developed and mass-produced by Shandong Innovation Building Materials Complete Equipment Co., Ltd. The series of products that have been formed can meet the requirements of various customers of different scales and requirements.

2. Technical indicators of composite smoke exhaust duct

1. Water absorption rate % 17.6

2. Bending strength/MPa 13.9

3. Impact strength/(kj/㎡) 9.0

4. Vertical load/KN 121

5. Flexible impact resistance without cracking

6. Combustion performance without burning

3. Equipment features

1. The equipment has a high degree of automation and low labor intensity. It can automatically complete sizing, main materials, and cloth laying, automatically flattening, and high-speed re-pressing. It is a large-scale equipment that can realize automatic functions such as automatic pallet loading, automatic slitting, and automatic board connection.

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

3. Flexible manufacturing of pipes, various specifications of smoke exhaust and exhaust duct products can be produced according to different requirements of customers

4. One machine can be used for multiple purposes, and can produce flue boards, fireproof decorative boards, ceiling boards and other products.

IV. Product features

The successful development of the composite smoke exhaust duct has completely solved the technical problem that the two important indicators of the current cement flue cannot meet the requirements of 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. The product adopts new inorganic refractory materials for mechanized production, and the fire resistance limit reaches more than 1.5h. According to the latest national JG/T194-2006 standard test, the vertical bearing capacity reaches more than 121KN (the national standard is ≥90KN), and the soft impact resistance is far higher than the national standard. It is light, crack-resistant, tensile-resistant, and easy to transport and install. It makes up for the quality deficiencies of cement flues and eliminates safety hazards. It completely solves the problem of smoke and odor in the kitchen. It is a new type of high-strength fire-resistant smoke exhaust and air duct with extremely stable and safe performance.
