How to distinguish between sintered clay brick and sintered coal gangue brick
Two kinds of brick color is not the same, the red clay brick, the brick surface slightly dark, in addition there are also differences between the surface of brick also has the difference between the former than the latter.
Sintered coal gangue brick with coal gangue as main raw material, sintering after selection, crushing, molding, drying and baking into non clay brick. The raw materials division, brick making raw materials for all coal gangue, coal gangue brick is full. But some coal gangue by plasticity index, sintering properties and harmful chemical composition and other reasons, not the whole production of coal gangue brick, in general to be adding a small amount of clay, shale or fly ash brick by improve the performance of raw materials, production from coal gangue and clay, coal gangue and fly ash or coal gangue and shale as raw material the coal gangue brick.
Because the main component of fly ash is some very small hollow or solid glass beads, the apparent density is very small, so the fly ash brick has light weight and good thermal insulation and sound absorption performance. The use of fly ash to make bricks, the consumption of fly ash is large, the proportion of fly ash in China's fired brick has been increased by more than 40%. The use of sintered fly ash brick can save energy, protect land resources and protect the environment. Therefore, it is one of the industrial projects that the state should give priority to and support.
Fired fly ash brick is a common brick made of fly ash as main raw material and mixed with cement such as coal gangue powder or clay. It is made up of ingredients, molding, drying and roasting. The utility model is characterized in that the clay can be saved, the fuel is saved, and the environment is protected. Because its wood property is the same as that of sintered clay brick, and its weight is lighter than that of the latter, it is a new type of sintered wall material which is easy to be popularized and applied.
Coal gangue is an industrial waste produced during coal mining. Using coal gangue as raw material for the production of new wall materials, both to protect the ecological environment, but also save the land, save energy, it meets the development policy of wall materials industry in China, is a new wall material attaches great importance to and vigorously support the development of the.
