1. Principle of coating machine

The film coating machine is a kind of film coating equipment that assists technicians in accurate film preparation. It simulates manual operation to provide a film coating environment with more uniform force and constant speed. It is generally matched with preparers and wire rods to control the film thickness.

The coating machine itself does not control the film thickness, which is determined by the scraper / bar of the coating machine.

2. Application of coating machine

 a. Coating material research

 The lab research will use a compact film applicator to produce consistent test charts for research after different formulations.

 b. Raw material

 Raw material manufacturers in the paint and coatings industry, such as adhesives, pigments, additives, colorants, solvents and resins, need reproducible sample drawings to define the role of their products in paint formulations in their R & D laboratories.

 c. Battery R&D

 The industry is eager to seek better and environmentally friendly batteries. Thin film technology plays an important role in this research. These laboratories use automatic film applicators to apply films, such as electrolytes from thin metal plates.

3. How to choose?

* Depends on the coating material

Scraper is used for those with high viscosity, and wire rod is used for those with low viscosity. Generally, the bottom end is used for heating, and the top end is used for rapid drying.

*Determin the coated substrate

Pay special attention to the flat substrate if the vacuum film cannot be adsorbed; If it is hard ground materials such as tinplate, it depends on the flatness and roughness. If the base material is too small, it is impossible to use the scraper, because the scraper depends on the height difference provided by the weight at both ends. In this case, it is good to choose the wire rod. However, if the viscosity is too high, samples or wire rods should be provided for trial use. Generally, the film is adsorbed by vacuum; Use normal glass plate for paper.

*Determine the coating size

Confirm the needed coating size (LxW) then choose the suitable coating machine is important.

Generally speaking, the coating machine is mainly to reduce the error caused by manual coating and improve the repeatability effect. One difference between imported and domestic products is the motor and the other is the coating plate. The smoothness, flatness and straightness of the plate directly affect the accuracy and effect of the coating film. The motor is mainly affected by factors such as vibration and service life. In order to reduce the vibration impact caused by the motor, many buyers will choose the coating machine with vacuum adsorption function and put the vacuum pump outside, a good way to reduce the vibration of the coating machine itself
