Coating machine knowledge handout ---

In the coating process, the coating gap is poor and the pole piece wrinkles are analyzed:

I. The phenomenon and cause of poor coating gap
1. Trailing
(1) Material: slurry material, viscosity, solid content, slurry (surface) tension
(2) Equipment: coating-back roller distance. speed of coating roller when back roller is opened. diameter of back roller. back roller surface material. back roller deformation. back roller and coating roller parallelism. back roller and oven front Rolls are not parallel. Tension in operation
(3) Operational aspects: parameters for head and tail adjustment 2. Head and tail are not parallel
(1) Material: the gravitational pull on both sides of the substrate
(2) Equipment: The back roller and the coating roller are not parallel. The back roller is not open when it is opened. The back roller surface is coaxial. The back roller and the traction roller are not parallel. The level changes. (3) The tension roller adjustment state.

PET film--


PET film is a relatively comprehensive packaging film. It has good transparency and luster; it has good air tightness and aroma retention; it has moderate moisture resistance, and its moisture permeability decreases at low temperatures. PET film has excellent mechanical properties, its toughness is the best among all thermoplastics, tensile strength and impact strength are much higher than general film; and it has good strength and dimensional stability, suitable for secondary processing such as printing and paper bags. . The PET film also has excellent heat resistance, cold resistance, and good chemical resistance and oil resistance. However, it is not resistant to strong alkali; it is easy to carry static electricity, and there is no proper antistatic method. Therefore, attention should be paid when packaging powdery articles.

(1) PET high gloss film
In addition to the excellent physical and mechanical properties of ordinary polyester films, the film also has excellent optical properties such as good transparency, low haze and high gloss. It is mainly used for high-grade vacuum aluminum plating products. The film is mirror-coated after aluminum plating, which has good packaging decoration effect; it can also be used for laser laser anti-counterfeit base film. The high-bright BOPET film has a large market capacity, high added value and obvious economic benefits.
