Film 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.

Equipment and materials required for a small film output center:

Most pad printing, silk screen printing and hot stamping processing companies can outsource film output business to professional film output centers, saving unnecessary funds and technical reserves. When your company has a certain scale and must establish its own film output center, you can refer to the following suggestions:

Image input equipment

Scanner: used to scan high-resolution images, manuscripts, etc.

Digital camera: take high-quality digital photos to provide clear image materials for film output.

Computer and related software

High-performance computer: equipped with multi-core processor, large memory and professional graphics card to smoothly run image processing software and perform complex image operations. Image processing software: such as Adobe Photoshop, Coreldraw, AI, etc., used for image editing, adjustment, color separation and other processing to prepare for film output.

Film output equipment/film processor/film developing machine

Laser imagesetter: Outputs image information from the computer to film, and is the core equipment of the film output center

Film processor: Develops and fixes the exposed film to make the image on the film clear, such as Kodak's small film processor, which can ensure the quality and efficiency of the processing. The consumables of the film output equipment should also be considered, such as film, developer, fixer, and water for washing.

The film output center has specific requirements for the environment, such as temperature, humidity, dust prevention, and lighting conditions, and should be set up according to the technical conditions proposed by the service provider.

Details-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.

Operation screen

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
The film processing machine adopts the upper and lower split structure, which is easy to clean and maintain, and the roller frame is easy to extract. Without the use of tools, the parts can be disassembled and maintained

How to treat wastewater from film developers?

Developers and fixers contain heavy metal ions such as silver, organic matter and other pollutants. Direct discharge will cause environmental pollution and must be discharged after targeted treatment.

Removal of pollutants

Sodium sulfide, ferrous chloride and other reagents can be added to make silver ions generate silver sulfide and silver chloride precipitation. Recovering silver after filtration and separation can reduce heavy metal pollution. Silver ions can also be reduced to metallic silver at the cathode through an electrolytic device, which is suitable for wastewater with high silver concentration. For the treatment of organic matter such as developers, oxidants such as hydrogen peroxide and sodium hypochlorite can be added to destroy the organic structure of developers (such as hydroquinone) and reduce COD (chemical oxygen demand) or coagulants such as polyaluminium chloride (PAC) and polyacrylamide (PAM) can be added to form flocs of colloidal organic matter and some heavy metals, which are separated after precipitation.

Reduce the concentration of pollutants

For low-concentration organic wastewater after pretreatment, use the biofilm method (such as contact oxidation pond) or activated sludge method to decompose residual organic matter through microorganisms; use ultrafiltration and reverse osmosis membranes to remove fine particles, residual heavy metals and organic matter in the water, and use activated carbon to adsorb residual pigments, organic matter and odor in the water to ensure that it meets the standards.

Post-treatment discharge requirements

Treated wastewater must meet local environmental protection standards before it can be discharged. Small enterprises can use integrated treatment equipment that integrates sedimentation, filtration, adsorption and other functions for treatment and discharge. Large production lines need to be equipped with a special sewage treatment system to ensure that the wastewater meets the discharge standards.
