Fly Processing Production Process

Fly ash brick is mainly used for the construction of the wall body and foundation, is in the siliceous and calcareous raw materials mixed with aggregate and plaster after mixing fly ash cement equipment compressed into silicate concrete products, so the use of common industrial and civil buildings. But it is worth noting that the fly ash brick because of the particularity of raw material, so cannot be used for building foundation and construction of easy to receive the freeze-thaw and the dry-wet alternate parts, also cannot be used in building long-term heating or heating speed, contain acidic materials.

From the selection of material, general brick of fly ash autoclaved fly ash brick, three types of pipe from fly ash brick, autotrophic fly ash brick, distinguishes between the three processed fly processing production process, and adopt the method of fly ash cement production is also slightly different, so lead to the performance of three kinds of fly ash brick also vary widely. Autoclaved fly ash brick is confirmed and vapor pressure maintenance, can make the strength of fly ash brick is higher, and the performance is more stable; And pipe is made by atmospheric pressure steam curing fly ash brick, because without the depth of the high pressure heat pipe from lack of water, so prone to cracking, and so on and so forth. Autotrophic main gel composition of fly ash is cement, fly processing production process is very simple, is natural curing after forming, so the production cycle than the above two kinds of fly ash brick is longer.

Fly ash brick compared with other buildings, more energy conservation and environmental protection, thus fly processing production process are more strict. In addition of fly ash can be used as fuel power plants, also can be a new raw material of fly ash brick, large area of industrial waste less pollution to the environment, at the same time can fly ash brick factory vigorously conserve farmland, compact layout of the factory to shorten the production cycle in great quantities, not influenced by seasonal and weather can do production throughout the year. In addition, the extent of the fly ash brick production automation machinery operation is very high, the roasting boiler not need regular brick production use, reduced the roasting of atmospheric pollution.

In addition, because fly processing production process requirements than sintered clay is superior, and the coefficient of thermal conductivity is smaller than sintered clay brick, is beneficial to improve the function of building, and accord with the requirement of the environmental protection industry policies in China, so many construction firms are starting to switch to fly ash brick used in non load-bearing parts of the building, can effectively reduce the cost of construction, has obvious economic benefits and environmental benefits.
