Under normal circumstances, high-quality styrofoam will not be baked. It has excellent temperature resistance and belongs to low-density elastomer. At the same time, it also has waterproof, flame retardant and other characteristics, and its cushioning performance is also good. But if it is poor quality styrofoam, it may be baked, because the quality is not up to standard, and the performance is definitely not good.
Matters needing attention in using styrofoam
1, styrofoam is a kind of solidified material, which can be sprayed at the designated position when used. But in the process of use, we should still pay attention to the use environment. If the place where the foaming material is sprayed is wet, the curing time will be short and the best effect can be achieved, so the base should maintain a certain humidity.
2. After the foam material is used up, it is still necessary to protect its surface under the condition of complete fixation, which can better protect the polyurethane foam material from being damaged. Because in daily life, when the cured foam material is irradiated by strong ultraviolet rays, it is easy to appear the phenomenon of surface yellowing, and it is also very troublesome to maintain.
3. If the tank needs to be replaced later, the prepared new tank needs to be shaken evenly. When unloading empty cans, it should be noted that this process needs to be completed as soon as possible to avoid solidification of the spray gun interface. When using the spray gun, close the flow valve in time to avoid waste.
