The development history of foaming machine

The foaming machine first appeared in foreign countries, and its original model uses the high-speed rotation of the impeller to make foam, so it is also called "foaming machine". Later, with the continuous advancement of technology, the technical content of foaming machines continued to improve, and new models continued to appear, forming different technical systems. my country began to use foaming machines as early as the 1950s, but it was not a special foaming model, but a mortar mixer. The foaming agent is directly added to the mortar mixer or concrete mixer, and the foaming agent and the mortar or concrete are stirred together to generate foam. Around the 1970s, special foaming agents, namely high-speed impeller foaming machines, began to appear. Since then, the technology has been continuously upgraded and replaced, and now it has developed into a third-generation model with high-pressure inflation as the main body, which can basically meet the needs of foam concrete.
