How to distinguish the quality of high-quality 4mmA2 fireproof aluminum composite panel protective film

How to distinguish the quality of high-quality 4mmA2 fireproof aluminum composite panel protective film

(Summary description)The viscosity of the surface protective film of high-quality 4mm A2 fireproof aluminium composite panel should be determined according to the smoothness of the material surface. The viscosity of the protective film for the board should be high. On the contrary, if you choose to use it improperly, it will cause the phenomenon that the sticking is not strong or the sticking is too strong and cannot be peeled off.

Information

  The viscosity of the surface protective film of high-quality 4mm A2 fireproof aluminium composite panel should be determined according to the smoothness of the material surface. The viscosity of the protective film for the board should be high. On the contrary, if you choose to use it improperly, it will cause the phenomenon that the sticking is not strong or the sticking is too strong and cannot be peeled off.

4mm A2 fireproof aluminium composite panel

  For a given surface, it is extremely important to choose the appropriate glue and viscosity, and the subsequent processing steps are the key to determining the viscosity. Subsequent processing generally includes bending and stamping. Generally, a low-viscosity protective film is used for smooth surfaces, and the viscosity is 0.9N/cm; for medium rough surfaces, a medium-viscosity protective film is used, and the viscosity is 1.2N/cm.

  It should be torn off as soon as possible after the decoration is completed. If the time is too long, the high-quality 4mmA2 fireproof aluminum-plastic board protective film will be weathered and dry and difficult to absorb. You can scrub the surface of the double-layer aluminum-plastic board protective film with hot water, and then slowly tear it off. Generally, it can be removed. Clean up. Find the two ends that are disconnected and gently pull them apart. Use a hair dryer to blow along the horizontal lines of the film. It will be slightly hot. Lift the two ends with both hands and pull down gently.
