Technical Field
The invention relates to the technical field of foam stabilizers, in particular to a production process of a composite foam stabilizer for pumpable ceramsite concrete.
Background
Along with the continuous promotion of the national energy-saving and environment-friendly requirements on buildings, more and more building floor surfaces are designed into light concrete for reducing dead weight and playing a role in heat preservation, heat insulation and sound insulation. Ceramsite concrete is used as a lightweight concrete with good heat preservation, heat insulation and sound insulation properties, and is widely used in building engineering gradually, but since the ceramsite density as coarse aggregate is small (the apparent density is generally not more than 1500kg/m 3 ) The ceramsite and the cementing slurry have larger density difference, so that when concrete is prepared, particularly when the concrete with large fluidity meeting pumping is prepared, the ceramsite is easy to float upwards and isolate in the transportation, pumping and pouring processes due to small density, and the pumping of the ceramsite is not removed, the pumping is blocked, and the pumping and pouring construction cannot be performed.
The composite blowing agent generally includes a foaming component and a foam stabilizing component. The foaming component is usually some surface active substances with excellent foaming performance, such as rosin, synthetic substances and protein foaming agents, and the foam stabilizing component enhances the stability of foam by increasing the viscosity of the solution and delaying the drainage of the film wall, and is usually some glue substances. The existing common compound methods mainly comprise a complementary method, a synergistic method and a function increasing method. The quality of the foaming agent is uneven, and the foaming agent is expensive, thereby being unfavorable for popularization, production and application.
In order to reduce pumping pressure loss, control ceramsite to float up in a large area due to vibration and solve the problem of holes caused by air which cannot be discharged and is caused by low fluidity, the invention provides a production process of a composite foam stabilizer for pumpable ceramsite concrete.
