Protective film is very important for some products. Its quality will directly affect its role. Therefore, when selecting protective film, we should also recognize its quality. To be on the safe side, it is better to test the quality of UV curing UV lamp protective film to ensure that everything is correct. What Xiaobian is about to describe is about this way.

Because of the particularity of the protective membrane structure, the quality of the protective film of the high pressure spray gun can be checked from the thickness of the PVC mask, because it is related to the impact force of the protective film.

Under normal circumstances, this layer of film thickness is best in 9 silk or so, in order to ensure the protection of product performance, this point as long as the micrometer can be accurately detected.

In addition, the toughness of the protective film needs to be tested. On the one hand, the simplest way is to pull the tear from the length of the mask first and pull the tear from the width direction of the film so as to clearly determine whether the toughness of the protective film product is up to standard.

Therefore, the elasticity and elongation with good toughness must be better, and the impact resistance is strong; The toughness is poor, brittle, thin and easy to tear, and the impact resistance is poor. When selecting the protective film, we must pay attention to it.
