Shenzhen foam concrete manufacturers tell you that bubbles are formed the basis of foamed concrete, foaming agent quality will directly affect the quality of foam concrete.
1, foam stability: good quality of preparation of cement foam bubbles, their film tenacious, the mechanical intensity is good, not easy to burst in a slurry extrusion or excessive deformation. In addition, it has a self-retention, liquid film on the water in a gravity under the action of surface tension and the loss can be long foam liquid film thickness and integrity, allowing the long bubble not burst. Stability foam slurry of liquid film difficult to break down in the body, is not easy to form a hole.
2, uniformity of foam: production of bubble bubble cannot be exactly the same, but it should be close, bubble diameter should be as small as possible, preferably in between 0.1~1mm.
3, bleeding rate: homemade foam after bleeding out gradually. Foam low bleeding rates in order to better guarantee the number of bubbles in the foam and foam concrete porosity, which is to ensure the density of foam concrete.
4, for the negative effect of cementitious materials: gel material is a major source of strength of foamed concrete, foaming agent foams prepared by very good stability, but after joining the cementitious materials will reduce the strength of foamed concrete or even lose their strength, so preparing to use foam not gel negative effects of foaming agent.
