VACUUM METHODS WITH BALLS FOR INSULATION AND PREVENTION OF NOISE AND ITS APPLICATIONS

摘要

The present invention relates to a vacuum insulation/noise preventing method using characteristics of a hollow sphere. The hollow sphere is filled inside a plastic film bag and of which pressure is reduced to form a vacuum body having various shapes as an independent module. The vacuum module where the hollow sphere is filled has a simple process to be capable of managing a perfect vacuum quality and has excellent strength to be extensively applied and has semi-permanent durability.
