[Recommendation] The working principle of the foam machine_The working characteristics of the foam forming machine

Hebei Changxing Foam Machinery Co., Ltd. is a company specializing in silicon polystyrene EPE foam machine, and its field is also quite prominent. Today we can learn more about the company's details. Beads after foam machinery and equipment A certain amount of foaming agent and water vapor are retained in the foam. When it is out of the machine, it will condense into a liquid, and the liquid foaming agent will dissolve into the polystyrene, so that the pressure in the bubbles will quickly decrease, and negative pressure (partial vacuum ), the beads are very soft and easily deformed. Therefore, when air is sent, try not to make the wind pressure too large, the inner wall of the air pipe should be as smooth as possible, and the bending radius should be as large as possible (to reduce collision resistance). The pipeline should be a good conductor of electricity, and the entire line must be grounded to avoid static electricity. For ignition, the transmission speed should not exceed 8m/s to avoid damage to the beads. A certain amount of foaming agent and water vapor are retained in the pre-expanded beads of the foam machinery and equipment. When they are discharged from the machine, they will condense into a liquid, and the liquid foaming agent will dissolve into the polystyrene to quickly reduce the pressure in the bubbles. , There is negative pressure (partial vacuum) in the bubble, and the beads are very soft and easily deformed. Therefore, when air is sent, try not to make the wind pressure too large, the inner wall of the air pipe should be as smooth as possible, and the bending radius should be as large as possible (to reduce collision resistance). The pipeline should be a good conductor of electricity, and the entire line must be grounded to avoid static electricity. For ignition, the transmission speed should not exceed 8m/s to avoid damage to the beads. The beads just out of the foam mechanical pre-expander are all damp. After being released from the pre-expander, they absorb air and suddenly encounter cold, causing the foaming agent in the honeycomb cells to condense and form a negative pressure in the cells, so the beads are in It must be placed for a period of time after pre-expansion. On the one hand, it is dried, and on the other hand, it is allowed to infiltrate air to eliminate negative pressure, so that the internal pressure and external pressure in the cells can be balanced to prevent the cells from collapsing and make the beads elastic. The process of drying, cooling and stabilizing the cell pressure of the EPS beads just out of the pre-expander is called maturation. Maturation improves the further expansion of the pre-expanded beads during the molding process, the fusion between beads and the elastic foam of the beads. The working principle of foam machinery is beneficial to improve the quality of EPS products.

Its control program is designed in a fool-style, simple, Convenient, no professional training is required to start operation. The full hydraulic drive of the foam molding machine has domestic hydraulic frequency modulation technology, which solves the adaptability of the foam molding machine to various materials, improves the compactness of the materials, and shortens the molding cycle. There are two necessary factors for the formation of foam, one is the foaming agent solution, and the other is air, both of which are indispensable. Without the blowing agent solution, the liquid film surrounding the gas would not form, and there would be no bubbles. And without gas, foaming agent solution alone cannot form bubbles. In the bubble formation system, the foaming agent solution is the dispersion medium, the gas is the dispersed phase, and the gas is dispersed in the liquid to form bubbles, and then numerous bubbles form the foam. In addition to the important factor of blowing agent performance, the introduction of gas into the blowing agent solution is another important factor. The introduction of gas into the liquid must be completed by the molding machine, that is, the foam molding machine adopts a certain method to introduce the gas into the liquid. The above is some introduction about 'the working principle of foam machinery'.
