Comparison of the advantages and disadvantages of laboratory film coating machine and manual film scraping?

difference contrast

Laboratory film coating machine and manual scraping film are two common coating methods, each of which has its own advantages and disadvantages. The following is a comparative analysis:

Film coating function: The film coating machine can control the speed, heat, and provide functions such as adsorption and smoothing of film materials, drying, and UV curing. It is difficult to complete the film in one step by hand.

Coating efficiency: The laboratory coating machine can achieve high-speed and large-area coating, and the coating efficiency is higher; while manual scraping needs to be done manually one by one, and the coating efficiency is low.

Coating precision: The laboratory coating machine adopts an automatic control system, which can achieve higher coating precision, especially for complex coatings such as thick films and multi-layer films; manual scraping is more suitable for simple coatings and small areas coating film.

Repeatability: The laboratory film coating machine can achieve high repeatability and consistency, because the thickness and quality of the coating can be automatically controlled according to the previously set parameters; it is difficult to ensure the consistency of the coating by manual scraping, especially are at different times or between operators.

Difficulty of operation: The laboratory film coating machine requires technical personnel to operate and maintain, and requires professional technical knowledge and experience; manual film scraping is relatively simple and can be operated by ordinary staff.

Cost: The price of the laboratory film coating machine is relatively high, requiring special equipment and maintenance costs; while the cost of manual scraping film is low, and it can be operated by simple hand tools.

In short, the laboratory coating machine and manual scraping film have their own advantages and disadvantages, and the appropriate coating method should be selected according to the specific coating requirements and experimental conditions. For experiments and production needs that require a large number of high-quality coatings, the laboratory coating machine has more advantages; for simple coatings and small-area coatings, manual scraping is more convenient, fast and economical.

how to choose?

The choice of coating method should be comprehensively considered according to specific needs and experimental conditions. Here are some factors for choosing a coating method:

Coating requirements: Different coatings require different thickness, consistency and surface quality, and the appropriate coating method should be selected according to the coating requirements.

Coating area: The size of the coating area determines the choice of coating method. The laboratory Film Applicator is more suitable for large area coating, while the manual scraping film is more suitable for small area coating.

Coating material: The physical and chemical properties of the coating material also determine the choice of coating method. For example, some coating materials require high-precision control and higher temperature and humidity control, and only laboratory film coating machines can be used.

Experimental Conditions: Experimental conditions should also be considered. If the laboratory does not have a laboratory coating machine, other coating methods need to be selected.

Experimental funding: Experimental funding is also a factor in choosing a coating method. Hand-scratched membranes are less expensive and are suitable for laboratories with limited budgets.

In short, when choosing a coating method, factors such as coating requirements, coating area, coating material, experimental conditions, and experimental funding should be considered comprehensively, and a suitable coating method should be selected according to the specific situation.
