The EPS intermittent pre-conditioning machine has such a function. What is the production process and working principle of the product? At the beginning, let’s first understand what an EPS intermittent pre-engine is. EPS batch pre-blower is a device that makes foam with a certain concentration of foaming agent aqueous solution. The foaming agent itself cannot become foam automatically, but it can become foam by the mechanical action of the foaming machine. The foaming machine and the foaming agent are technical systems that cooperate with each other, and the two cannot function alone. Therefore, the product itself cannot create bubbles out of thin air. It is to introduce air into the foaming agent aqueous solution to make it evenly dispersed to achieve a possible liquid-gas contact surface, so that the surface active substances in the foaming agent are formed on the surface of the foaming agent, and the surface of the liquid film forms an electric double layer , surrounding the air to form bubbles.
Then it’s about how it’s produced, how it works. The EPS intermittent preview machine retains a certain amount of foaming agent and water vapor after being pressurized, and condenses into liquid when discharged from the machine, and then dissolves the liquid foaming agent into polystyrene, so that the pressure in the bubble drops rapidly, and negative pressure appears in the bubble. Pressed, very soft and easily deformed. Therefore, try not to make the air pressure too high during air delivery, the inner wall of the air duct should be as smooth as possible, the bending radius should be as large as possible, and the pipeline should be a good conductor, so that the entire pipeline should be grounded to avoid static ignition and prevent damage to the beads. The beads on the newly produced EPS intermittent previewer are wet. After coming out of the machine, the foaming agent in the honeycomb pores is condensed due to the sudden cooling of the inhalation, and negative pressure is formed in the pores. Therefore, the beads are placed for a period of time, on the one hand, they are dried, and on the other hand, they penetrate into the air to eliminate the negative pressure, so that the internal pressure can be balanced with the external pressure, so as to avoid cell collapse and make the beads elastic. The beads are dried for a certain period of time, and the bubble pressure is stable. After ripening, the foaming agent and water vapor in the cells condense into a liquid, forming a negative pressure in the cells. At this time, air penetrates into the cell through the cell membrane, balancing the pressure inside the cell and the pressure outside, so that the hairball is elastic. Ripening is also different, generally can be divided into natural ripening method and pressure ripening method. This is how the production of the product works.
EPS intermittent pre-engine, with the continuous progress of the economy, the product is also constantly improving, maybe one day, the use function of the product will be greatly changed, thereby improving the efficiency of production and truly realizing the fully automated process.
