How to solve the problem of foam cement separation and precipitation

     Foaming cement and precipitation occurs in the process of construction and separation has always been a key factor affecting product quality, the early people attributed the quality of foam agent, think there is a good foaming agent can make the ideal foam cement, (here ideal foam cement refers to the general after cement foam can make no separation, precipitation, strength, have uniform hole, is not true low bulk weight, high strength, uniform closed hole, pore clear dense, aperture moderate insulation, can meet the thickness of more than 1000 mm of a pouring construction.) In fact, in recent years, there have been a variety of new foaming agents that can meet the current construction requirements, But there are still a lot of separation and precipitation problems in the market, Therefore, the author has solved the problem in the past two years, But it still cannot completely solve the problem of separation and precipitation, In the discussion of improvement, it is found that the existing equipment can not meet the requirements of product deepening research, The process flow and formulation adjustment we developed cannot be achieved on the old equipment, From this, we found that, The quality of the foaming cement is mainly affected by three major factors, First, the process technology, The second is the material ratio (including the foaming agent), Third, the technical conditions of the equipment, In addition, the quality changes caused by the operation level and responsibility in the construction, We know that even in the past few years, when the equipment and technology is relatively backward, there are still good products, But the stability of a good product is difficult to control, In addition, if there is a good foaming agent can also make a little better product, But its stability is also difficult to control, All these problems show that the mass stability of foam cement is affected by many factors, Therefore, our company also focuses on the deep development of equipment in addition to the research of process formula, So that the performance of the equipment can meet the requirements of product development; 1. The equipment shall have all the process flow of the foaming cement, Each process should be simple and reliable.2. To fit into the variability and accuracy of the ingredients.3. With advanced control technology to achieve operability.4. Develop a set of process standards and operating procedures.5. Determine the technical objectives of foaming cement, foaming agent and foaming machine. The following new foaming machine, foaming agent for some discussion.

    the cement foaming machine is the key equipment of the current foaming cement products. At present, the market sales of cement foam machine is imported from South Korea and domestic imitation, Despite the different manufacturers, There are technical differences between the different models, But its basic performance has not changed much, The main reason is that the initial application of foam cement is mainly limited to ground heating and insulation construction, And the floor heating insulation construction to "self-leveling" pumping cast-in-place technology, So the performance of the equipment has been around the floor heating and insulation development, Due to the superior properties of the foaming cement, In recent years, some enterprises, in addition to the construction of floor heating and insulation, Has developed to the roof, wall, insulation brick and other fields, Use the original equipment to test the more required products, And the original equipment in the product function development ability is far from adapted, Research and development of new equipment has been listed as a development target, In recent years, some enterprises have developed small, light non-pumping foaming machine is designed for roof construction, sporadic insulation construction, product development, Its weight and structure have changed greatly, Small volume and light weight equipment provides a guarantee for small construction, Dragon minicomputers currently on the market, Weight is less than 100kg, And the bubble production and mainframe phase approximate. With the continuous increase of sporadic sites and the expansion of the application scope, the large output light machine has also been on the market, this kind of model in the premise of the quality control of the product has made a lot of optimization and improvement.

1. weight from more than 1 tons to 500kg output increased, some per hour can reach 30m2

2. volume from a few meters to 1.6, meters, meters wide, meters, 1.4 meters high, installation space is less than two square meters, the supporting mixer, feeding machine also miniaturization, can meet the requirements of various construction site, some even can all equipment into a dozen square meters of room construction, greatly facilitate the environmental requirements of the construction unit.

3. the improvement of the control system, improve the product control ability in the process of production, to adapt to the product adjustment of fast, simplification, the application of electronic injection technology make the foaming agent accurate adjustment and random strain into reality, avoid the waste of liquid medicine, ensure the stability of the product, multifactor variable control measurement basic make the product quality has risen a quantity level.

4. cement slurry processing and foam processing mixed older models qualitative change, provide technical support for processing high quality foam cement, foam is not only good uniform, and can greatly save foaming agent, and can replace different types of foaming agent at any time, without its foaming multiple determination and test, a few minutes can adjust accurately

5. after the optimization of pumping technology, not only for light and efficient, low energy consumption, more make the service life of pumping and maintenance convenient to achieve the ideal state, new pumping technology pneumatic push principle, and extrusion conveying principle, minimize the pumping high voltage pulse, effectively protect the integrity of the foam, the pumping process foam crushing is almost zero, the delivery pressure, determined by conveying height and resistance, pumping function automatically adjust to adapt to the pressure, to achieve the purpose of "soft" pumping, ensure product quality and stability.6, the single-chip microcomputer program controls the application of the frequency converter, to provide the foaming machine with the convenience of the operation and function. Simplify the control, increase the function, for the special high-performance intelligent automation equipment to provide hard, software support, some old models through the selection of frequency converter also improve the operability. In short, the new foaming machine highlights a "new" word, it is the new technology, new process, new products, new material innovation embodiment.
