Clean workshop is a special work area designed to control dust, microorganisms and other contaminants in the environment. They are commonly used in industries that require a highly clean and sterile environment, such as pharmaceuticals, biotechnology, medical device manufacturing, and electronics manufacturing.
The design and operation of clean workshops aim to minimize or eliminate fine dust and microorganisms in the air to ensure the quality and safety of the production process. These workshops typically use special air filtration systems, strict environmental controls, and regular cleaning procedures to maintain a high level of cleanliness.
In clean workshops, personnel are often required to wear special protective clothing and masks to prevent external contaminants from entering the work area. Cleanroom levels are typically classified based on their allowable limits on airborne particles, such as those specified in the ISO 14644 standard.
Clean workshops are widely used in many fields. Here are some common scenarios:
Pharmaceutical Industry:
The pharmaceutical industry has extremely high requirements for a clean environment and is used in drug manufacturing, drug packaging and filling.
Medical Device Manufacturing:
When producing medical devices and equipment, the presence of microorganisms and other contaminants needs to be strictly controlled to ensure product safety and quality.
Electronic Manufacturing:
In the manufacturing process of chips, semiconductors and other electronic equipment, clean workshops can reduce the impact of dust and other particles on electronic devices.
Food Processing:
In some food processing processes, especially for highly sensitive food products (such as certain beverages, dairy products, etc.), a clean environment is required to ensure product hygiene and quality.
Aerospace Industry:
In the aviation and aerospace fields, clean workshops are used to manufacture aviation parts and aerospace devices to ensure their performance and safety.
Laboratories and Research:
Scientific research laboratories require clean environments to conduct experiments that are sensitive to microorganisms and the environment.

Cleanliness grade is a standardized grading system used to describe the degree of cleanliness. It is usually used to measure the number and size of particles in the air in a clean environment. These rating systems usually classify based on the size and amount of particles in the air, with the most common standard being the ISO 14644 standard.
The ISO 14644 standard defines cleanroom cleanliness classes that describe the number of particles of a fixed size in the air. Specific levels include:
1. ISO 1 to ISO 9: ISO 1 is the highest level of cleanliness, and ISO 9 is the lowest. ISO Class 1 means there are no more than 10 particles of 0.1 microns (microns) or less per cubic meter of air. As the rating decreases, the amount of particulate matter allowed increases accordingly.
2. ISO 14644-1 Standard: This standard also defines the design and operational requirements for clean rooms to ensure that cleanliness levels are maintained.
Each industry may have specific requirements for cleanliness levels to ensure product quality and safety.
1. Superior Design Flexibility and Speed:
* Design Flexibility:
Steel structures offer greater design freedom and can be customized into a variety of shapes and sizes to meet the specific layout and space needs of a cleanroom.
* Quick Build:
Steel structures are usually assembled much faster than concrete, allowing clean workshops to be built faster, shortening the construction period, and putting them into use quickly.
2. Lightweight and Durable:
* Lightweight:
Steel structures are relatively light, which reduces the weight of the building and reduces the requirements for foundation and supporting structures.
* Strength and Durability:
Steel has exceptional strength and durability, allowing it to withstand repeated loads and impacts while maintaining structural stability and integrity.
3. Sustainability and Ease of Maintenance:
* Recyclability:
Steel structure materials have high recyclability, which is conducive to sustainable development and environmental protection.
* Easy to Maintain:
Steel structures are generally easier to maintain, and coating or anti-rust treatments can extend the life of the structure and reduce routine maintenance costs.
4. Fire safety and environmental adaptability:
* Fire Safety:
Steel structures generally perform better in the event of a fire than concrete, making it easier to predict and control the effects of a fire.
* Adapt to Environmental Changes:
Steel structures are more adaptable to environmental changes and are easier to carry out structural adjustments, expansions or renovations.
While steel structures offer many advantages, concrete also has its advantages in certain situations, such as greater sound insulation and fire resistance. Therefore, when choosing building materials, you need to take into account the needs and environmental conditions of the specific scene, and comprehensively consider various factors to make the most appropriate choice.
