Fiber-reinforced exhaust duct

Abstract

The invention belongs to component and fittings in the field of architecture, and specifically relates to a fiber-reinforced exhaust duct. The fiber-reinforced exhaust duct is characterized by being made from the following raw materials of: by weight, 100 parts of portland cement, 5-10 parts of waste paper pulp fiber, 10-17 parts of asbestos fiber, 1-3 parts of a polypropylene substance and 1-1.2parts of a special-purpose auxiliary agent. By changing wastes into the main raw materials of the product, the invention is energy saving and environmentally friendly, and simultaneously is used to save a large amount of national resources and completely solve the problem of flying dust generated during the whole production process. In addition, a lot of machines are adopted to replace artisan craftsmanship, thus greatly improving the working environment for workers and mitigating their labor intensity.

Description

technical field [0001] The invention belongs to components and parts in the construction field, and in particular relates to a fiber-reinforced exhaust duct. Background technique [0002] At present, the production of exhaust ducts is still dominated by traditional manual powder and assembly of magnesium oxychloride, and there are also appropriate mechanically formed exhaust ducts with traditional sand and gravel as the main raw material. However, the exhaust ducts of handmade powder cannot meet the requirements of various indicators of the industry standard at all, and have gradually withdrawn from the market. So we began to study the use of mechanical forming instead of manual production, but the weight and flexibility of traditional materials still require a large number of steel bars to meet, which is a serious waste of materials, and there are certain risks in fire resistance. Manufacturers have begun to study the use of magnesium oxychloride materials to replace tradi...

However, the exhaust ducts of handmade powder cannot meet the requirements of various indicators of the industry standard, and have gradually withdrawn from the market

So we began to study the use of mechanical forming instead of manual production, but the weight and flexibility of traditional materials still require a large number of steel bars to meet, which is a serious waste of materials, and there is a certain risk in fire resistance.

Manufacturers have begun to study the use of magnesium oxychloride materials to replace traditional sand and gravel materials to overcome the requirements of its flexibility and fire resistance. However, due to the essential characteristics of magnesium oxychloride materials, its molecular structure is extremely unstable, such as durability, halogen return , dampness, and deformation are problems that cannot be solved in China at present.

Furthermore, the magnesium oxychloride exhaust duct is basically assembled, and the amount of labor required in the production process is huge, not only the production cost is high, but also the working environment is extremely poor
