Foam concrete block introduced from abroad to China has for many years, state and industry introduced related standards and technical norms, JC/T1062-2007 foam concrete block and JG/T266-2011, foam concrete application technology rules JGJ/T341-2014 and so on. Due to the characteristics of heat preservation, sound insulation, light weight and environmental protection, the development of this product has been in our country for many years, but the production process has not been a great breakthrough, so that there has been no large-scale application.
There are several aspects of restricting our country new wall materials and foam concrete block development: Formula 1, the domestic manufacturers of the technology is relatively backward, the intensity of the product is low, amounting to less than national standard. 2, manufacturers did not use the advanced automatic production line, production efficiency is low. Due to the above reasons as manufacturers Wei Jian investment brick, light brick.
Guangzhou Ou re building materials Co., Ltd., the introduction of Europe and the United States the latest technology and foam concrete block equipment, so that the production level of China's foam concrete block to reach a new height. 1, the use of special initial setting kiln technology, shorten the initial setting time of cement foaming; 2, accelerate the release time, through constant temperature and humidity conditions, let raw material for producing block rapid contraction shaping to achieve the best coagulation condition of, so do 5-8 minutes fast demoulding. The above two points not only solve the problem of strength but also solve the problem of output.
Foam concrete block production of raw materials are: water, cement, fly ash, foaming agent and other materials. Production process: the cement and fly ash and other raw materials to fully mixing, using the European compound special cement foaming technology to fully foam after the automatic pouring into the mold. After 10 to 8 minutes after the initial coagulation can be cut, the product after professional conservation, 3 to 7 days after the intensity of the detection of 3.5Mpa.
