Abstract

A ventilating and air-discharging pipe relates to a ventilating pipe, in particular to a lightweight ventilating and air-discharging pipe. The invention provides a ventilating and air-discharging pipe with low cost, light body, thin wall, and easy-cutting and ideal ventilation effect. The technical scheme is to mix magnesia, magnesium chloride, coal ash, agricultural wastes and the chemical preparation at the ratio of 1:1-1. 2:0. 3-0. 35:0. 25-0. 3 by weight.

Description

Technical field: [0001] The invention relates to a ventilation duct, in particular to a lightweight ventilation exhaust duct. Background technique: [0002] At present, most of the existing ventilation ducts and smoke exhaust ducts in buildings use cement as the main raw material. The disadvantages are high cost, weight, wall thickness, and inability to cut, which brings great trouble to the construction; moreover, the ventilation effect is not ideal. Invention content: [0003] The present invention aims at the above problems and provides a ventilation and smoke exhaust duct with low cost, light body, thin wall, easy cutting and ideal ventilation effect. [0004] The technical scheme of the present invention is achieved like this: the present invention is that magnesium oxide, magnesium chloride, fly ash, agricultural waste, chemical preparation are mixed; By weight, magnesium oxide: magnesium chloride: fly ash: agricultural waste is 1:1-1.2:0.3-0.35:0.25-0.3. [0005] ...
