Formula 1 cement bricks, clay: to contain a certain amount of loose particles in order to facilitate mixing cement. Less sand clay, can be equipped with sand in the soil. Less sand and hard clay, after adding sand to be milled. 2, cement: 10% incorporation of 425 # ordinary portland cement, brick can improve the strength and water resistance permeable planting brick mold, cracking after immersion in water. Otherwise, there will be general brick cracking phenomenon. 3, admixtures: the incorporation of a small amount of additives (booster), apart from increasing the strength of brick sclerosis, but also reduce the amount of cement, reduce product costs. 4, water: water suitable planting brick mold, brick strength is high. Forming less water, the difference between the strength of brick, the material in the mold resistance, single-sided pressure is not dense brick bottom surface; forming more water, the bottom surface of moist, easy to break something when the mold. When the sand moisture content of 3-5%, water consumption by 10% during molding is appropriate. If too much material pre-planting brick mold sand, then dropped to 8%. Plastic Mold is most commonly used plastics processing industry mold processing, plastic products businesses can give exact dimensions and configuration of the whole through the plastic mold. However, as the brick mold plastic mold four holes to plant trees, its varieties and processing methods also varied. Moreover, a variety of plastic products, construction and production process is simplified varying. This has resulted in species diversity and structure of the plastic mold. Modern economic development is very much to promote the development of industries, including plastic mold as a plastic processing Dong drama, and its development is very rapid. Plastic has many component parts, the function of each of these parts is not the same, making the plastic mold has become a relatively complex processing tools. In general, the total can be divided into two parts and the movable mold fixed mold, and the two parts is composed of a plurality of systems. Purpose, structural plastic mold very complex, which also makes plastic mold processing becomes very complicated. This can produce a wide variety of plastic products.
