In order to obtain the pore structure conforming to the technical requirements, it is necessary to have the foam which conforms to the technical requirements, and the two are basically corresponding. What quality bubble, what kind of stoma also has?. The basic technical requirements of the bubble are as follows: 5 are indispensable. First, the higher the stability of foam, the better the bubble time Foam with good stability, good mechanical strength and hard to break or excessive deformation under slurry extrusion. In addition, it has self water, the water film is not easy to lose in the gravity and surface tension, can maintain the integrity of foam film thickness and long time, which can make the long time remaining and not burst bubble. 1., the stability of the bubble on the pores of the impact of three: most of the bubble does not disappear, in the slurry after the initial setting is fixed in the foam concrete, the formation of pores. Foam stability is not good, most or less part of the foam in the pouring after the collapse, the formation of pores rarely, and even in the soon after pouring slurry collapse, that is commonly known as collapse, resulting in completely failed pouring. 2., a good stability of the foam, the slurry is not easy to deformation under the extrusion too large, there is a certain pressure to maintain their approximate sphere, but eventually form a good hole shaped spherical pores; 3. foam with good stability, the liquid film is difficult to break in the pulp, and it is difficult to form the communicating hole formed by the collusion of the gas after the rupture. Therefore, it eventually forms
