Embodiment Construction

[0017] In the embodiment of the present invention, magnesium oxychloride material is used to produce a combined fireproof exhaust duct for kitchen and bathroom. The material formula of the embodiment of the present invention is: 100 kg of magnesium oxide, 60 kg of magnesium chloride, 40 kg of expanded vitrified microbeads, 2 kg of polymer A, and 1.5 kg of modifier B. Prepare the materials according to the above formula and put them into the mixer. After mixing evenly, enter the composite sheet forming machine to press into a sheet and coat it with glass fiber mesh cloth, and finally demould it. According to the above formula and process flow, the sizes of the two types of plates to be pressed are: 3000mm×250mm×7mm, 3000mm×236mm×7mm, each of which is produced in an even number of pieces; then according to the above formula and process flow, press the back shape on the special mold The inner frame and the cross-section are right-angled triangle strips. The size of the back-shape...

Abstract

The invention relates to a combined fireproof kitchen-toilet exhaust passage and a method for producing the same. The combined fireproof kitchen-toilet exhaust passage comprises a plate, an inner frame and a bar stock. The inner frame is shaped like a Chinese character hui; the cross section of the bar stock is shaped like a right-angle triangle; all the components of the combined fireproof kitchen-toilet exhaust passage are produced by pressing the magnesium oxychloride material into preformed parts and then combing and bonding the preformed parts. The magnesium oxychloride material comprises90-115 kg of magnesium oxide, 55-67 kg of magnesium chloride, 35-40 kg of expanded and vitrified small balls, 1.0-3.0 kg of macromolecule polymer A and 1.0-1.5 kg of modifier B. Produced from the magnesium oxychloride material to which the expanded and vitrified small balls are added with the corresponding process, the combined fireproof kitchen-toilet exhaust passage has greatly improved fire resistance, heat resistance and flame retardance, is light, firm and durable and can be produced on a large scale.

Description

technical field [0001] The invention relates to a flue gas fire-proof exhaust duct for a residential kitchen and bathroom and a manufacturing method thereof, belonging to the technical field of construction. Background technique [0002] Kitchen and bathroom exhaust ducts are an indispensable part of residential buildings. Traditional residential kitchen and bathroom exhaust ducts are generally made of concrete. The wall thickness of the concrete pipes is generally 1cm. There are many problems. The traditional cement flue duct The production is all manual operation, and the thickness of the product is uneven; the traditional cement flue gas duct is highly alkaline, and ordinary glass fiber mesh cloth is used as the reinforcing material of the cement flue duct, and its strength is lost quickly, which directly affects the life of the flue duct; The exhaust gas temperature of the kitchen is high. During the use of this kind of pipeline, cracks often appear, which will cause the...
