The increasingly rapid development of the new century, the development of China clay brick faster and faster, with the continuous development of the economy, the material of the wall to meet the continuous improvement of people's quality of life becomes more and more operators and people's requirements, our company is the production of a multi-functional materials clay brick. Clay brick, also known as the fired brick building man-made small bulk, clay brick clay (including shale, coal gangue powder) as the main raw material, mud treatment, molding, drying and roasting. , Solid and hollow, respectively. September 26, 2012, the National Development and Reform Commission announced that China will "Twelve Five" period in Shanghai and other hundreds of cities and the county to progressively restrict the use of clay products or disable the solid clay brick. Clay brick clay (including shale, coal gangue powder) as the main raw material, mud processing, molding, drying and roasting
Square and elongated brick gradually created in China as early as the Spring and Autumn Period, the Qin and Han Dynasty brick-making technology and scale of production, quality and varieties of fancy has a significant development, the Bank said "Qin brick tile. The ordinary brick dimensions of 240 mm × 115 mm × 53 mm, divided into according to the size of the compressive strength (N / mm ², in N/mm2) MU30, MU25, MU20, MU15, MU10, MU7.5 6 Power Level . Clay bricks using local resources, cheap, durable, as well as fire protection, thermal insulation, sound insulation, moisture absorption, etc., widely used in the civil construction. Waste and scrap bricks can also be used for concrete aggregates. For the improvement of the ordinary clay brick block small, since the major drawback of many soil consumption, the forward direction of lightweight, high strength, hollow, large development. Sand-lime brick to an appropriate proportion of lime and quartz sand, sand or fine-grained sandstone, finely ground, add water, mixing, semi-dry method is extruded and made autoclave curing. Fly ash bricks, fly ash as the main raw material, mixed with the of gangue powder or clay cementing material, ingredients, molding, drying and roasting can make full use of industrial waste, saving fuel.
China clay brick Al2O3 content is generally above 40%, the Fe2O3 content less than 2.0% to 2.5%. Ingredients 65 to 85% clinker, 35 to 15% binding clay. The crushing combination of clay and finely ground clinker mixed grinding, particle clinker preparation of semi-dry mud, high pressure molding, firing at about 1400 ° C, and better performance. Clay brick at a high temperature, a weak acid, anti-alkaline slag erosion is a bit weak, but enhanced with Al2O3 content increases. The thermal stability of silica brick, magnesia brick (see magnesia brick) as well.
Acceptable quality blast furnace clay brick by drying vacuum impregnated phosphate, the second low-temperature firing of phosphoric acid impregnated products for masonry lining of blast furnace body part. Such as the production of clay bricks.
I believe that our production of clay bricks will be more in line with the requirements of the people, I will continue to work hard.
