Why is plastic film made of hand made paste of composite material?
FRP hand lay up after the release, must be to achieve, but the smooth emergence is very important, because of the characteristics of thin flat and smooth, easy to make glass steel and mould to form two layers, not due to the small defects of the mold surface due to adhesion, so that the surface is beautiful and easy demoulding.
Glass steel production quality, surface quality is an important aspect, because only the smooth surface, smooth transition, the surface will completely cured resin, coherence, no weak points, in order to better erosion resistance medium. Hand paste operation itself is very difficult to do this. But the film is easy to improve, because the film itself is made of the machine, the surface is smooth and smooth, and the film has better toughness, can guarantee the convex, concave point transition smooth.
Films play two roles, on the one hand, make the surface quality better (the film needs to be laid flat), on the one hand, it is convenient to release and prevent adhesion.
