Sintering and non-sintering process itself makes […]
Sintering and non-sintering process itself makes the product is essentially different. No matter what kind of raw materials, because whether clay, shale, coal gangue, fly ash, from the mineralogy point of view, the main component of them are "clay material", sintered by sintering and can be made of high strength, Long-lived wall masonry materials, such masonry buildings up to several hundred years of their lives. The non-sintered block there are many significant performance defects, mainly in:
1, Non-sintered blocks have relatively high energy consumption and resource consumption throughout the production process. Non-sintered block products are through the cement (or gypsum) as a gelling agent, add sand, stone and various industrial waste, through natural conservation or (pressure) steam curing to solidification, block masonry material. As a cementitious material, cement consumes a large amount of non-renewable resources, such as limestone and clay, as well as a large amount of coal and other high-quality energy sources, and emits huge amounts of carbon dioxide in the production process. In the production of concrete, a large amount of limestone blocks The economic value of limestone resources consumed by the two is far greater than the economic value of clay resources used in burning bricks. Walls built with non-sintered blocks have a very high heat transfer coefficient, making them much more energy efficient than walls made of sintered blocks, a typical high-energy-consumption building. Does not meet the national energy saving industry policy.
2. The characteristics of the raw materials of the non-sintered block determine its drying shrinkage value is large, the performance and volume stability period is too long, making the construction of the wall prone to deformation cracking during use and other issues.
3, with non-sintered block construction of the wall has a very high heat transfer coefficient, the use of energy consumption is much higher than the sinter block construction of the wall, is a typical high-energy buildings. Does not meet the national energy saving industry policy.
4, non-sintered block of uncomfortable and environmental protection
Non-sintered block does not have insulation, noise, breathing and other functions, does not meet the green and comfortable building needs. It is difficult to separate and completely recycle after the end of its service life, and it can only become environmentally unfriendly garbage.
5, non-sintered block construction of the house because of its lack of energy-saving building requirements, the need to use the paste or paste within the insulation method,http://www.576dz.com
