Usage

Application field

• Printing industry: It is used to wash films for printing plate making. High-quality films are the basis for achieving precise printing, which is directly related to the clarity and color accuracy of printed products.

• Medical imaging: Washing films produced by medical examination equipment such as X-rays and CT. Clear and accurate images are crucial for doctors to accurately diagnose diseases.

• Advertising production: Wash the film in the advertising design to ensure the high-quality output of the advertising picture, which is used for the production of large posters, light box advertisements, etc.

Development principle:

After exposure, the film enters the developer of the film processor, and the chemical components in the developer react chemically with the exposed photosensitive material on the film. The photosensitive material in this area is converted into a visible black or other color image material, and the image gradually appears. In the unexposed area, the photosensitive material reacts very slowly or almost not at all with the developer. The photosensitive material in these areas remains basically the same and will be removed or retained as a blank part in the subsequent processing process, thus forming a developed image corresponding to the exposure pattern. After development, the film enters the fixer, and the unreacted photosensitive material on the film fixes the image that has been formed. The chemical components in the fixer can react with the unreacted photosensitive material, dissolve it and wash it off the film, leaving only the stable image that has been developed. After the fixation process, the image on the film will no longer be affected by subsequent chemical treatments or external factors. After the fixation is completed, the film needs to be dried to remove the residual developer and fixer on the film. Water such as dry film is dried for subsequent use and storage.

Basic structure

• Chemical tank part: It includes multiple chemical tanks, which respectively hold developer, fixer, washing water, etc. The chemical tank is usually equipped with a circulation system to ensure uniform concentration and temperature of the chemical solution.

• Conveying system: It is composed of motors, rollers, gears, etc., which can accurately control the conveying speed and position of the film in the medicine tank and drying area, ensure that the film stays in each processing area for a sufficient time, and ensure the washing and drying effect.

• Drying part: There are two common methods: hot air drying and heated drum drying. Hot air drying blows the heated air to the surface of the film through a fan; heated drum drying allows the film to pass through the heated drum surface and achieves drying through heat conduction.

• Control system: It can realize precise control of parameters such as washing temperature, time, conveying speed and drying temperature. Parameters can be entered manually, or multiple washing modes can be preset to meet the washing needs of different types of films.

Details

Function principle

• Flushing principle: Film processor realizes flushing based on the chemical reaction between chemical agents and photosensitive materials on the surface of film. After the film is exposed, the chemical composition of its photosensitive layer changes. Chemical solutions with different functions in the film processor act on the film in turn, and the latent image formed by exposure is converted into a stable and visible image through chemical processes such as development and fixing. For example, the developer reduces the silver halide in the exposed part to silver, and the fixer removes the unexposed silver halide, thereby fixing the image.

• Drying principle: The washed film is quickly dried through a hot air circulation system or a heating roller to avoid residual water stains affecting the image quality.

Operation screen

Machine advantage

The microcomputer operating system is simple and convenient, with high stability, and realizes automatic control. Turn on the power switch to automatically enter work.
For the program.When the temperature of the medicine reaches the set value, put the film in for washing, and automatically turn on the roller drive system.
Fixing and developing, water washing valve, drying and heating systems are all done in one go. When there is no film, it will automatically enter the energy saving state
Microcomputer display, menu-type data setting modification program, upper and lower split design, wide dark.
A series of innovative designs such as boxes, large-capacity collection boxes, anti-oxidation devices for liquid medicines, etc.
The body adopts galvanized sheet structure to ensure no Will rust, the sink is made of imported stainless steel, which is sturdy and durable, and the traction roller is wear-resistant, corrosion-resistant and resistant Aging and high temperature resistance.
Worm gear guides are processed by high-quality imported plastic molds, which are durable.
The side plate of the fixed roller adopts imported stainless steel, which is stronger and more durable than the plastic side plate
