Frame material

The frames of cleanrooms are usually made of industrial aluminum profiles, stainless steel squares or iron squares sprayed with plastic, which are solid, beautiful, non-rusting and non-dust-producing. Aluminum profiles are widely used for their light weight, ease of processing and affordability, while stainless steel squares are used in more demanding environments for their excellent corrosion resistance and mechanical properties.

Wall Material

The walls of clean booths are usually made of anti-static drapes or acrylic panels. These materials have good anti-static effect and high transparency, which can effectively block the entry of dust and particles, and at the same time are easy to clean and maintain.

Filtration system

The filtration system inside the clean room is the core part, usually using FFU (Fan and Filter Unit) fan filtration unit, the system through the high-efficiency filters, can provide a constant flow of clean air, to ensure that the air quality in the clean room.

Other Materials

In addition to the above materials, the clean room may also contain other auxiliary materials, such as special purification lamps, anti-static carpet, etc. The selection of these materials should also be decided according to the specific clean requirements and working environment.

Classification and application of clean room

Clean room can be classified into different categories according to the cleanliness level, such as class 100, class 1000, class 10,000, class 100,000, etc., and its cleanliness standard is based on ISO 14644 or other industry standards. Clean room can not only be used alone, but also can be used in combination with other clean equipment to adapt to different application requirements and scenarios. In industrial production, clean booths can effectively prevent dust, bacteria and other pollutants from affecting the production process, while in the field of healthcare, clean booths are used in operating rooms, sterile rooms and other key areas to ensure medical safety and hygienic conditions.

Advantages and disadvantages of clean rooms

The advantages of clean booths are their quick construction, ease of maintenance and flexibility to provide a highly clean environment in a short period of time. However, due to the extensive use of filtration equipment and fans, clean rooms can be noisy and can feel stuffy inside due to the air supply. In addition, if the clean room is not constructed in a clean room, it may lack the protection of intermediate efficiency filters, resulting in a relatively shorter service life for high efficiency filters and higher costs in the long term.

Preparation before installation

Before installing a clean shed, it is first necessary to ensure that the environmental conditions of the installation site, such as dry, ventilated, well-lit, etc., and to meet the special requirements of specific industries, such as anti-static, anti-corrosion, etc.. In addition, the clean room needs to be thoroughly cleaned and wiped to ensure that cleanliness requirements are met.

Foundation construction

The foundation construction of the clean shed should meet the design requirements to ensure that the foundation is level, solid and horizontal. After the foundation construction is completed, acceptance should be carried out, and the installation of clean shed can be carried out only after passing.

Frame Installation

The frame of the clean room is usually made of steel, and the verticality and levelness of the frame should be ensured during the installation, and anti-corrosion and anti-rust treatment should be carried out after the frame installation is completed.

Ceiling and wall plate installation

The ceiling and wall panels should be made of purification boards or other materials that meet the cleanliness requirements. When installing, make sure the flatness of the ceiling and wall plate, and the joints are tight to avoid loopholes.

Air purification system installation

The interior of the clean shed should be equipped with an air purification system, including high-efficiency filters, air showers, ultraviolet disinfection lamps and so on. When installing, make sure the connection between components is tight to avoid air leakage.

Lighting System Installation

The interior of the clean room should be equipped with a lighting system, such as LED lamps and lanterns. When installing, the waterproof and dustproof performance of the lamps and lanterns as well as the uniformity of illumination should be ensured.

Electrical system installation

The electrical system of the clean room should meet the relevant national standards and industry requirements. When installing, it should ensure the stability and safety of power supply, as well as the normal operation of each electrical equipment.

Grounding treatment

The grounding treatment of the clean room should meet the design requirements to ensure the safe operation of the equipment inside the clean room.

Acceptance and debugging

Clean shed installation is completed, acceptance should be carried out. After acceptance, the clean shed debugging to ensure that the normal operation of the system to achieve the desired clean effect.

Aerodynamics

The aerodynamic design of a clean room is based on the needs of the environment and the production process, and centers on the determination of key parameters such as air velocity, number of air changes and static pressure. The air velocity needs to be set to meet specific requirements to ensure effective particle suspension and transportation. The number of air changes also needs to be moderate, in order to achieve a reasonable ventilation effect. Static pressure refers to the pressure difference between the inside and outside of the clean room, usually required to maintain a positive pressure state to prevent the intrusion of external pollutants.

Noise control

Noise is an important consideration in the production of clean room, and its limitations have a direct impact on the protection of employee health and product quality. According to the health standard, the noise limit in the clean room should be controlled within a certain range, which can be realized through the use of acoustic materials and acoustic panels and other means of noise reduction.

Illumination requirements

The illuminance of the clean room is closely related to its internal productivity and should meet the hygiene standards and work requirements. Appropriate illumination level can be realized by suitable light source, common lighting equipment including incandescent lamps, fluorescent lamps and LED lamps.

Comprehensive Environmental Elements

In addition to the above three aspects, the environmental elements of the clean room also include temperature, humidity, etc., which need to be reasonably managed and regulated. During the design process, all possible factors in the production process should be considered comprehensively, and appropriate measurement standards should be determined accordingly.
