Abstract

The invention belongs to a production method of a fireproofing flue of an environmental-friendly building and an exhaust duct in a washroom. The method comprises the steps of bittern making, mixed pulping, forming, maintaining and the like of raw materials comprising magnesium oxide, magnesium chloride, fibrous fragments and accessories. The fireproof plate, a kitchen flue and the exhaust duct in the washroom of the environmental-friendly building have the advantages of high mechanical strength, incombustibility, energy conservation and environmental friendliness. Tested by the national quality surveillance examination test center for building material and industrial housing building material, the environmental-friendly building fireproof plate, the kitchen flue and the exhaust duct reaches the quality and technical index stated by the nation in the aspects of mechanical strength, fireproofness, hydrolytic resistance, formaldehyde release limit and the like. The on-site analog experiment is carried out on the kitchen flue and the exhaust duct in the washroom by the national surveillance examination test center for air-conditioning equipment, and flues at 36-story floor height are tested, reach the quality and technical index stated by the nation, and have the performances of environmental friendliness, fireproofness, corrosion resistance and the like as compared with the cement chimney, and avoids the backward flow phenomenon in air draft.

Description

technical field [0001] The invention relates to a production method of a flue and an exhaust duct, in particular to a production method of a fireproof flue and an exhaust duct, including a kitchen flue and a bathroom exhaust duct. Background technique [0002] With the rapid development of social economy, building an ecological, environmentally friendly city, and a harmonious home living environment is the aspiration of all human beings. The use of land is becoming increasingly tense, and the government has introduced more and more policies on land use. In this context, urban residential buildings are concentrated, and high-rise residential buildings will be the subject of extensive construction. [0003] The kitchens, bathrooms, and exhaust ducts of today's high-rise residential buildings are mostly near the windows. Every household used to emit oily fumes and exhaust gases outside their windows, resulting in a situation where cooking is done downstairs and smoke is emitte...
