Preparation method of negative oxygen ion heat preservation air duct

Abstract

The invention discloses a preparation method of negative oxygen ion heat preservation air duct in the technical field of heat preservation air duct preparation, The method comprises the following steps: a. Cleaning, b. Laying, c. Welding, d. Compacting, e. Sewing, f. Detecting, the invention has good heat preservation effect and simple cleaning, the traditional industrial washing machine can be cleaned, and the content of small particle size negative oxygen ions in the inner layer is high, reaching 3000 pieces / cm3. 10000 / cm3, which is convenient for purify that air in the controlled area, remove the peculiar smell, adsorbing the PM2.5 particles, and the negative oxygen ion material on the inner wall of the air duct also has bacteriostatic effect, the bacteriostatic rate is above 90%, and the flame retardant grade of the heat preservation air duct is up to GB8624 2012 Grade B, S1 d0 t0, smoke density as low as GB / T8627 2007 <= 15, toxicity grade of tobacco production is GB / T8627 2006is not less than ZA2.

Description

technical field [0001] The invention relates to the technical field of preparation of thermal insulation air ducts, in particular to a preparation method of negative oxygen ion thermal insulation air ducts. Background technique [0002] With the prosperity of the country, the improvement of science and technology, the development of industry has also been greatly improved. Insulation ducts can be seen on the walls everywhere in the factory workshop. Through the intake and exhaust of the insulation ducts, it is convenient to improve the air quality in the factory workshop. It is convenient for workers to continue working. [0003] In the prior art, some conventional thermal insulation ducts have the following disadvantages: [0004] 1. Conventional thermal insulation ducts use rubber-plastic insulators, glass fiber, and asbestos as thermal insulation materials. This material has poor folding resistance, cannot be machine washed, and is bulky and difficult to transport; [0...

AI Technical Summary

Problems solved by technology

[0004] 1. Conventional thermal insulation ducts use rubber-plastic insulators, glass fiber, and asbestos as thermal insulation materials. This material has poor folding resistance, cannot be machine washed, and is bulky and difficult to transport;

[0005] 2. Conventional thermal insulation ducts are complex to install, difficult to sew, and difficult to shape;

[0006] 3. Conventional thermal insulation air ducts are not easy to clean, resulting in a lot of dust accumulated on the inner wall of the air ducts, easy to breed bacteria, and poor ventilation quality. Therefore, we propose a preparation method for negative oxygen ion insulation air ducts
