The production line of the dust-free injection workshop has a wide range of products, such as cosmetic containers, lighters, bathroom accessories, auto parts, smart electronic accessories, etc. It is a basic supporting industry with a wide range of application industries. In view of the characteristics of plastic products, they need to be It is produced in a safe and dust-free space, so the injection molding dust-free workshop has also emerged. Plastic raw materials, toners, nozzle materials, molds, injection molding machines, peripheral equipment, fixtures, sprays, various auxiliary materials and packaging materials are used in the production process of the injection molding dust-free workshop. Injection molding production requires 24 hours of continuous operation. The production process It is easy to produce non-methane total hydrocarbon waste gas, and prolonged exposure has an impact on the human body. Therefore, according to the precision requirements of the industry and the different production processes, the injection molding dust-free workshop has a large difference in the purification level, and it needs to be analyzed separately according to the specific situation. During the construction process, the designers of CEIDI Xidi will emphatically consider the emission of exhaust gas and the treatment of dust. Air treatment is also the key content of the design and decoration construction of the dust-free injection workshop.

Air purification system for decoration and construction of dust-free injection workshop

The air purification treatment in the decoration system of the dust-free injection workshop should adopt three-stage filters of primary, medium and high-efficiency filters. Its working principle is: outdoor air → wet curtain → primary effect filter → medium efficiency filter → (central air conditioning heating or cooling) → high-pressure fan → air supply duct → high-efficiency air supply outlet → clean room → exhaust gas collection bell mouth → exhaust air Charcoal waste gas treatment equipment) → high-pressure exhaust fan → discharge at an altitude of 15 meters.

1. By installing a dust-free air-conditioning box, the air purification and filtration can meet the design requirements. According to the actual situation of the customer, design a 100,000-300,000-level dust-free air-conditioning purification box

2. A large amount of hot exhaust gas will be generated during the injection molding process, which must be discharged into the clean room as soon as possible through reasonable collection to maintain the dust-free requirements of the working environment.

3. For centralized emission of exhaust gas, according to the requirements of different local regulations, add activated carbon exhaust gas treatment equipment (for example: the new injection molding machine factory project in Shanghai Pudong must do exhaust gas treatment before emission is allowed)

The main structural materials for the decoration and construction of the dust-free injection workshop

1. The ventilation ducts of the dust-free workshop are made of galvanized sheet steel, and PEF flame-retardant insulation board is used for insulation.

2. The ground adopts epoxy self-leveling or high-grade wear-resistant plastic dust-free floor.

3. The wall and roof materials of the dust-free workshop are generally made of 50mm thick sandwich color steel plates and alumina profiles for purification.

4. The door adopts a clean airtight door, and the window adopts aluminum alloy glass fixed window.

Of course, the clean room purification project is a particularly widely used industry. When some precision manufacturing content in the application industry requires more than 100,000 cleanliness requirements, local cleanliness projects in the injection purification workshop will also be built, such as:

1. Set up a clean bench: Class 1~100.

2. Set up a clean work shed: In order to enclose a small space in a turbulent clean room space with anti-static transparent plastic cloth, use independent HEPA or ULPA and air-conditioning blower units to become a higher level of clean space. The grade is 10~1000, the height is about 2.5 meters, and the covering area is less than 10 square meters. The four pillars and the installation of movable wheels can be used for flexibility.

With the development of modern products in the direction of high-quality, precise and cutting-edge, more and more companies have cooperated with CEIDI to achieve win-win results. CEIDI has also been focusing on the development and deepening of engineering in the field of professional cleaning, and continues to create iconic clean system projects.
