Zibo fired clay brick antique brick, aluminum silicate clay mineral is some prolonged weathering products, with strong stickiness named. After the water is made to reconcile the clay brick, brick placed calcined (about 1000 ℃) has made bricks. Clay contains iron Beijing Antique brick, generate red ferric oxide, that the most common red brick firing process when complete oxidation; and if added to the cooling water in the firing process, the iron in the clay incomplete oxidation generated cheap iron (FeO) then was blue, that brick. Brick and red brick hardness is about the same, just different methods of cooling after firing, and the red brick is a natural cooling, simpler Hebei antique brick, so now produce more red brick, brick water cooling (in fact, one kind of hypoxia cooling) antique brick, operate more trouble, so now the production is relatively small. Although the strength, hardness similar, but the performance in terms of antioxidant brick, hydration, atmospheric erosion was significantly better than the red brick. A continuous kiln fired brick tiles, by tunnel kilns and furnaces and exhaust * duct, exhaust * Road connection between the tunnel kiln drying kiln import and import, exhaust trail * provided with a blower; tunnel kiln along the inlet to the outlet into the preheating section, high-temperature section, insulation segment, steam humidification section shifted in order as well ... The utility model discloses a ribbon of asphalt tiles, including the top body and lower body, the upper layer is provided between the body and the lower body of the steps, the upper body is provided above bitumen layer with non-slip strips on the lower body. The utility model using bitumen layer between the tile joints easily overcome and tipped into the gray water phenomenon ...
