When foaming with a sponge foaming machine, how does the sponge foaming machine foam?
First, the sponge foaming agent should be adjusted as needed, and then the adjusted sponge foaming agent is poured into the sponge foaming machine. The sponge foaming agent contains beads which do not foam before 80 ° C but only continuously spread out. When the temperature exceeds 80 ° C, the beads in the sponge blowing agent begin to swell and soften, forming cells that are not connected to each other. Steam due to an increase in temperature also enters the cells, and the pressure in the cells increases. As the temperature rises and the time goes by, the above process continues until the air pressure in the cell is so large that the cell is broken, and finally our common sponge is produced. This is the working process of the sponge foaming machine. It reminds the user of the sponge foaming machine that the sponge foaming agent must be adjusted. Otherwise, the sponge machinery with good quality can not produce a high quality sponge. This is meaningless. Because consumers are becoming more and more critical now, sponges of poor quality will eventually be eliminated. In order to make the company survive better, the details must be paid attention to.
For chemical sponges, it is mainly made of polyurethane soft foam rubber, which is often used in the manufacture of insoles, sponges in daily life, and the like. For foamed cotton, the main raw material is polyether, which is processed by professional mechanical equipment. For the regenerative sponges that have been popular in recent years, they are mainly formed by the extrusion of industrial sponges with specific glue. No matter what kind of sponge is produced, we must choose a good quality sponge foaming machine. Its quality will directly affect the quality of the sponge.
