Energy-saving brick promotion into the "fast track"

The traditional "Qin brick Hanwa" had a glorious period in the history of the city's architectural application. The Changshu brick and tile factory had reached 138 at most. However, in the development of urban construction in the past 20 years, such building materials fired from clay have become more and more serious due to land destruction and air pollution when raw materials are collected and burned. New wall materials with excellent energy-saving and consumption-reducing effects will have greater use in this situation. According to calculations made by the staff of the Municipal Wall Materials Reform and Building Energy Conservation Office, the city’s annual output of conventional brick and tile plants is 275 million standard bricks, although it only accounts for 10% of the total amount of wall materials in the city, but if these All materials are replaced with new wall materials, and less 2522 mu of land can be excavated each year (in order to dig two meters deep), which greatly saves land resources.

According to the latest statistics from the Economic and Information Commission, there are 20 new wall material manufacturers in the city, with a production capacity of 2.3 billion standard bricks. These new wall materials can guarantee the city's architectural applications and save land in terms of quality, and are divided into six major categories: autoclaved aerated concrete blocks, concrete blocks, concrete porous bricks, sludge bricks, and color steel plates. New composite wallboard wall building materials. Among them, two types of environmentally-friendly products such as autoclaved aerated concrete blocks and new composite wallboard type building materials have a good response in this market.

Autoclaved aerated concrete blocks are widely used in this city, and major environmental protection projects such as the Changshu Public Mansion and the Huating Villa Area have adopted this kind of environmental protection building materials. This year, Golden Elephant Wall Materials Co., Ltd., established through the reorganization of assets, used ** foaming technology to produce brand-new autoclaved aerated concrete blocks, accelerating the marketing of such environmentally friendly building materials. After the product is processed by this technology, quartz sand replaces the clay material and becomes a lightweight porous material with a density of only 1/3 of the red brick and 1/4 of the ordinary concrete, and is also convenient for loading and transportation. At the same time, the product's thermal insulation effect is 6 times that of clay bricks and 12 times that of ordinary concrete, which can save 50% of electric energy for the use of indoor air-conditioning. After all production is completed, the Golden Elephant Wall can form a production capacity of 200,000 cubic meters to meet the city's and surrounding areas' demand for environmentally-friendly wall materials.

Changshu Keying Composite Material Co., Ltd. is a leading company in the research and development of new types of composite wallboard type building materials. The company invested more than 30 million yuan last year to develop a multi-functional lightweight composite wall. The weight of materials used per square meter of this type of wall is only 35 kilograms. Compared with ordinary walls, the weight is reduced by 90% and the thickness is reduced to 10 centimeters. However, it can also achieve the thickness of 28 cm traditional wall fire prevention, sound insulation and other physical performance indicators, can save a lot of construction steel and concrete, reduce the cost of 5% of the housing. This year, the product has entered the stage of market launch, and it is expected that 500,000 square meters of sales and 75 million yuan of sales will be generated next year, accumulating strong momentum for the renovation of wall materials.
