Processing method of exhaust gas duct

Abstract

The invention relates to the technical field of building materials, in particular to a processing method of a flue gas exhaust flue. The processing method of the flue gas exhaust flue comprises the following processing steps of (1) carrying out material batching, wherein magnesium oxide, coal ash and wood chips are mixed in proportion to form a mixed material; (2) carrying out stir, wherein a magnesium chloride solution is added to the mixed materials formed by the magnesium oxide, the coal ash and the wood chips, and the materials are stirred to form a slurry agent; (3) carrying out material injecting, wherein glass fiber cloth is placed into a mould cavity of a rectangular pipeline mould, the rectangular pipeline mould comprises a mould body and a mould core, and the mixed material which is stirred is injected into the cavity formed by the mould body and the mould core; (4) carrying out vibration, wherein vibration is carried out after material injection is accomplished; (5) carrying out mould release operation, wherein a vibrated product is placed, and then mould release is carried out. According to the processing method of the flue gas exhaust flue, the fireproof temperature is high, and can range from 800DEG C to 1000DEG C; due to the fact that the coal ash is used, waste materials can be made profitable, industrial waste is effectively utilized, high strength and the high fireproof temperature are ensured, it is ensured that the weight of products is light, carrying and construction are conveniently carried out, processing efficiency is effectively improved through integral forming, and the products further have the advantages of being high in strength and the like.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a processing method for a smoke exhaust duct. Background technique [0002] The smoke exhaust duct is a pipe installed in a building to discharge the smoke and waste gas in the kitchen and toilet to the outside space in a concentrated manner, and is used to eliminate the oil fume or dirty gas in the toilet produced by cooking activities in the kitchen; in the prior art , using glass-magnesium combined flue gas duct, which is mainly formed by cutting and assembling the formed glass-magnesium plates, which is easy to be assembled, the overall shape life is short, the structural strength is not enough, it is easy to leak, and the assembled parts are easy Scattered in the flue to block the flue pipe, there is a potential safety hazard. During the assembly process, straight nails are required. The straight nails cannot be rust-free and non-oxidative for a long time in an al...

[0002] The smoke exhaust duct is a pipe installed in a building to discharge the smoke and waste gas in the kitchen and toilet to the outside space in a concentrated manner, and is used to eliminate the oil fume or dirty gas in the toilet produced by cooking activities in the kitchen; in the prior art , using glass-magnesium combined flue gas duct, which is mainly formed by cutting and assembling the formed glass-magnesium plates, which is easy to be assembled, the overall shape life is short, the structural strength is not enough, it is easy to leak, and the assembled parts are easy Scattered in the flue to block the flue pipe, there is a potential safety hazard. During the assembly process, straight nails are required. The straight nails cannot be rust-free and non-oxidative for a long time in an alkaline environment. Impurities are produced during the cutting of the board, which is harmful to the human body. It is healthy, and it is easy to cause injury to the staff, the remaining materials will pollute the environment, and the processing efficiency is low
