Description

Technical Field

[0001] The utility model belongs to the technical field of testers, and in particular relates to a heat-insulating solar film tester. Background Art

[0002] Solar film is also called heat insulation film. In modern solar film production technology, vacuum spraying or magnetron sputtering technology is often used to make aluminum, gold, copper, silver and other metals into multiple layers of dense high-insulation metal film. In addition to heat insulation and light insulation, it also has explosion-proof function. High-quality explosion-proof film uses a special polyester film as the base material. The film itself has strong toughness and is combined with special pressure-sensitive glue. In case of an accident, the glass will be firmly bonded by the film after it breaks and will not splash and injure people. After the solar film processing is completed, samples of appropriate size need to be taken for quality testing, such as heat insulation and light insulation effects.
