Description

A method for making refractory lightweight particle wall on-site spraying and filling

technical field

Background technique

At present, my country's building energy consumption accounts for about 1/3 of the total energy consumption of the whole society. The living area of heating cities in northern my country only accounts for 10% of the national urban living area, but building energy consumption accounts for 40%.

Compared with developed countries with similar climate conditions, the heating energy consumption per square meter of buildings in our country is about three times that of developed countries. my country is currently making every effort to promote building energy saving by 65%. standard.

Gypsum board and light steel keel are common materials for making partition walls, and it is common practice to cut and fill rock wool into them. This method is more energy-saving and environmentally friendly than concrete casting or aerated brick stacking. However, because the rock wool is manually cut and filled on site, and the horizontal and vertical keels in the wall increase the amount of labor, often only one working hour is required. It can make several square meters, but the efficiency is low. In particular, the application of low-cost organic insulation materials such as foamed polystyrene, foamed polyurethane and foamed phenolic formaldehyde in building insulation is greatly limited due to low flame retardancy and fire resistance; foamed perlite, foamed ceramics, foamed glass , Foamed cement and other inorganic thermal insulation materials are heavy and have poor thermal insulation effect, and require a large amount of adhesive to bond with the two side panels, and also require a lot of manpower and high cost for cutting.
