During the production process of optical lenses, the requirements for the production environment are extremely stringent. As Guangzhou Cleanroom Construction Co., Ltd., with our deep accumulation and rich experience in the purification equipment field, we are dedicated to creating a production environment that meets high standards for enterprises. Today, we will provide a detailed interpretation of the construction standards for optical lens constant - temperature and humidity dust - free workshops.
I. Cleanliness Standards: The Cornerstone of Quality
For optical lens production, cleanliness is directly related to the quality and performance of the lenses. Usually, the cleanliness of an optical lens constant - temperature and humidity dust - free workshop needs to reach Class 10,000 or even higher standards. Taking the Class 10,000 cleanliness level as an example, the number of dust particles with a size of 0.5μm or more per cubic meter should be controlled within 352,000. Such strict restrictions on the number of particles are to prevent dust particles from adhering to the surface of the lenses during key processes such as lens grinding and coating, thereby avoiding defects such as scratches and spots and ensuring the optical performance and imaging quality of the lenses.
II. Temperature and Humidity Control Standards: Fine - Tuning is the Key
1. Temperature
The workshop temperature generally needs to be precisely controlled within 23°C ± 1°C. The materials of optical lenses are mostly glass or resin. These materials have different thermal expansion coefficients, and even a slight change in temperature may cause changes in the size and shape of the lenses, thereby affecting the accuracy and imaging quality of the lenses. The advanced temperature control system provided by our company can ensure that the temperature in all areas of the workshop is uniform, providing a stable temperature environment for lens production.
2. Humidity
The relative humidity needs to be maintained within the range of 45% ± 5%. Appropriate humidity can effectively prevent dew formation on the lens surface, avoid lens mildew and corrosion caused by moisture. At the same time, it can also reduce the generation of static electricity and prevent dust from being adsorbed by static electricity to contaminate the lenses. Through professional humidification and dehumidification equipment, combined with an intelligent humidity monitoring system, precise control of the workshop humidity can be achieved.
III. Airflow Organization Standards: Creating a Pure and Stable Production Environment
1. Unidirectional Flow
In the core processing areas of the lenses, such as the coating area and the high - precision grinding area, the unidirectional flow airflow organization form is often adopted. Air is sent vertically downward from the high - efficiency filters on the ceiling, flows through the work area at a uniform speed, and then is discharged from the air return vents on the ground. This airflow form can quickly carry away dust particles and pollutants in the work area, maintain a high level of air cleanliness, and provide a guarantee for the high - precision processing of the lenses.
2. Turbulent Flow
In some auxiliary areas, such as the material storage area and the personnel passageway, the turbulent flow airflow organization method can be adopted. By reasonably arranging air supply outlets and air return outlets, the air forms irregular flows in these areas, which can not only meet certain cleanliness requirements but also reduce costs. At the same time, by setting reasonable pressure differences, it is ensured that the air in the clean area will not be affected by the back - flow of air from the polluted area.
IV. Building Material Standards: The Solid Guarantee of Quality
1. Ground
Antistatic, wear - resistant, and easy - to - clean materials, such as antistatic epoxy self - leveling floors, are selected. This kind of floor can not only effectively prevent the damage to the lenses caused by static electricity generated by personnel walking and equipment operation but also has good wear resistance and chemical corrosion resistance. It is convenient for daily cleaning and maintenance and can maintain good service conditions for a long time.
2. Wall
Color steel plates are used as the wall materials. The surface of the color steel plates is smooth, without pores, not easy to accumulate dust, and convenient for cleaning and disinfection. At the same time, it also has good thermal insulation performance, which helps to maintain the stability of the temperature and humidity in the workshop and reduce energy consumption.
3. Ceiling
The ceiling also adopts color steel plates and is closely connected to the walls to ensure the airtightness of the entire workshop. The high - efficiency filters on the ceiling are installed in precise positions, which can ensure the efficient filtration and uniform distribution of air, providing clean air for the workshop.
