Mortar and concrete mixers foaming process
This is the most primitive of the foam machine at home and abroad, can not be called a true sense of the foam machine. But, this foaming method in China, many companies still use. This foam is the blowing agent and joined together with cement and aggregate mixer, concrete materials in the pulp or the system, while relying on the mixer blade into the air, so that blowing bubbles and foam entering into the mortar or concrete inside. It will foam and bubble mix into one of the process equipment. The advantage of using this process equipment is simple, without the purchase of specialized foam machine, simple process, small investment. Its main deficiency is not fully effective foaming agent, foaming efficiency up to 50%, very few bubbles. More important is the size of the bubble uneven, affecting foam stability and strength. And its a great amount of foam arbitrary and difficult to control. Using this process equipment, in the same amount of bubbles in the case, only a small multi-purpose foaming agent 2 to 4 times. In general, this type of blowing agent for entraining mortar and concrete type, or dosage requirements of the bubble is very low, mortar and concrete density of 1500 kg / m higher than the density of mortar or concrete, not suitable for production 1500 kg / m below the lower density concrete, is not particularly suitable for 700 kg / m below the low-density concrete, can not be produced. Currently, some domestic enterprises in this original production process equipment and low-density concrete products, while saving money, equipment, simple process, but it is very unscientific, the cost is very high, and the concrete and the performance of products can not be guaranteed. Thus, the foaming process should be eliminated.
