How is plastic foam foamed?The steam generator tells you the answer

“Plastic foam” is a polymer material formed by a large number of gas micropores dispersed in solid plastic. It has the characteristics of light weight, heat insulation, sound absorption, shock absorption, etc., and its dielectric properties are also better than resin. Today, its societal uses are so wide that almost any plastic can be made into Styrofoam. It is also one of the most widely used plastics in the world. In the production process of plastic foam, it needs to be carried out under the action of high temperature and high pressure catalyst, and the polymerization reaction occurs in a closed reactor. The steam generator is also one of the important production equipment for the foam plastic factory to produce foam plastic. It mainly provides high-quality steam for foam production and assists foaming.
1. Chemical foaming: mainly using chemical reagent foaming agent, etc., to generate bubbles in the plastic through thermal decomposition. This bubble mainly exists in polyurethane foam, and in this process, a steam generator is required to provide a stable heat source for decomposition. Our steam generator can provide a stable heat source, and the time and temperature can be adjusted, so that chemical foaming The process will not be interrupted.
2. Physical foaming: dissolve the plastic with other gases and liquids, and then make the plastic expand. This method does not alter the original shape of the plastic. In this process, a third-party expansion effect is used to evaporate the plastic. A steam generator is used to provide a heat source to dissolve other gases and liquids in the plastic, which then produces a material expansion reaction.
3. Mechanical foaming: The method of mechanical mixing is mainly used to melt the gas into the mixture and extrude it by external force. In this process, a steam generator is also needed to assist.
Therefore, the steam generator is very suitable for the production of plastic foam. Various foaming methods require the use of steam generators, and the national demand for foaming needs to meet food hygiene requirements. The actual use of traditional boilers is very limited. The steam generated by our steam generators is high-temperature and clean, which fully complies with national standards.
Nobles steam generators are actively used not only in the plastic foam industry, but also in the food industry, medical industry, mechanical industry, cleaning industry, greenhouse cultivation, heating and other industries. Our steam generators are all in use.
