What are the requirements and standards for class 100 clean room?
Specifically depends on the application in what industry
10 level 100 level thousand level 100,000 level 100,000 level 300,000 level million clean room design requirements - different levels of clean room design is mainly to meet the requirements of its level on the line, as follows:
Hundred thousands of biological clean room level table
Ten thousand hundred thousand biological clean room level table
Pharmaceutical clean room ABCD four levels
Pharmaceutical industry level
Clean room air changes
Clean room pressure difference table
Looking at the adoption!
The difference between class 100, class 1,000, class 10,000 clean room?
1, the dust particle capacity is not the same.
Thousand level clean room 0.5 micron dust particles less than 9 million, hundred level clean room 0.5 micron dust particles less than 1 million.
The dust particles of 5 microns in a class 1,000 clean room are less than 50,000, and the dust particles of 5 microns in a class 100 clean room are less than 0 million.
2, the workshop uses different
100-class clean room can be used for the pharmaceutical industry, such as aseptic manufacturing process, a large number of applications in the plant, such as the manufacture of items in the body, surgery, including transplantation surgery, the manufacture of integrators. Thousands of clean room is mainly used for the production of high-quality optical products, but also used for testing, assembly of aircraft snake screwdriver, assembly of high-quality miniature bearings and so on.
3, different sterility
Hundred clean room is not a sterile room, a thousand clean room on the "sterile" or "dust-free" environment to be strict.
Clean room, also known as clean room, dust-free workshop, dust-free room or clean room. The main function of a clean room is indoor pollution control, without which mass production of pollution-sensitive parts is impossible. Inside FED-STD-2, a cleanroom is defined as a room with air filtration, distribution, optimization, and construction materials and devices in which specific rules of operating procedures are used to control the concentration of suspended particles in the air in order to achieve the appropriate level of particulate cleanliness.
Introduction
Clean room cleanliness and control of contamination of the continued stability of the clean room is to test the quality of the core standards of the clean room, the standard according to the regional environment, the degree of purification and other factors, divided into a number of grades, commonly used international standards and domestic industry standards in the regional, a number of well-known purification engineering companies, in the prevailing standards, but also has its own implementation of the higher than the international standard of prevailing Some well-known purification engineering companies, in addition to the prevailing standards, also has its own implementation of higher than the international standards of purification indicators, purification capacity and environmental adaptability far beyond the international brands. Generally industrial aluminum as a framework, the use of fan filter unit FFU air supply, surrounded by anti-static curtains, the top cover seamless blind, forming a seamless area, the internal purification level of up to 100 - 100,000; especially suitable for local cleanliness requirements in the workshop area, such as assembly line work area of high-precision product assembly area.
What is the standard of clean room?
Clean room means to control the air pressure, humidity, temperature, etc. in a certain index, so that the spatial environment in line with certain production conditions.
Clean room is divided into different standards according to the cleanliness level, different cleanliness level cleanliness standards are as follows:
1, class 10: 0.1um concentration ≤ 10, 0.2um concentration ≤ 2. This level belongs to the high-level purification project, applicable to precision, micro electronic technology industry.
2, 100 level: 0.1um concentration ≤ 100, 0.2um concentration ≤ 24, 0.3um concentration ≤ 10, 0.5um concentration ≤ 4, this level is a common grade, applied to the pharmaceutical industry, sterile manufacturing.
3, 1000 level: 0.1um concentration ≤ 1000, 0.2um concentration ≤ 237, 0.3um concentration ≤ 102, 0.5um concentration ≤ 35, 1.0um concentration ≤ 8, this level is used in the production of micro-axis, optical devices.
4, 10000 level: 0.1um concentration ≤ 10000, 0.2um concentration ≤ 2370, 0.3um concentration ≤ 1020, 0.5um concentration ≤ 352, 1.0um concentration ≤ 83, this level is used in the production of hydraulic equipment or food and beverage.
5, 100000 level: 0.1um concentration ≤ 100000, 0.2um concentration ≤ 23700, 0.3um concentration ≤ 10200, 0.5um concentration ≤ 3520, 1.0um concentration ≤ 832, 5.0um concentration ≤ 29, this level is used in many industrial fields.
6, 1,000,000 level: 0.1um concentration ≤ 1,000,000, 0.2um concentration ≤ 237,000, 0.3um concentration ≤ 102,000, 0.5um concentration ≤ 35,200, 1.0um concentration ≤ 8,320, 5.0um concentration ≤ 293, this level of purification degree is lower, mainly used in the printing plant, packaging plants and other cleanliness This level of purification is low, mainly used in printing factories, packaging factories and other industries that do not require high cleanliness.
Per cubic meter will be less than 0.5 micron particle size of the number of dust control in the 3500 below, it reached the international dust-free standard of A level. Currently, the dust-free standard applied in chip-level production and processing is higher than Class A, and such a high standard is mainly applied in some higher-grade chip production. The amount of dust is strictly controlled at less than 1,000 per cubic meter, which is commonly known in the industry as the thousandth level.
The choice of address of the clean room should be in line with the principle of favorable production, convenient life, saving investment and operating costs. Dust-free workshop and traffic spacing between the main road should be more than 50 meters.
The factory site should be located in the natural environment and water quality is better, the atmosphere contains less dust concentration, topography, features, landforms caused by the microclimate conducive to the production of energy-saving areas, should be far away from a large number of emitting dust, smoke, toxic gases and microorganisms in the area, such as airports, railroads, wharves, traffic routes, and so on, and in the source of contamination and the year-round dominant wind direction of the wind upwind side, and there is a certain distance of protection.
Is the air fresh in a class 100 clean room
Fresh air.
Class 100 clean room: Class 100 clean room can be used in the pharmaceutical industry, such as aseptic manufacturing processes, this clean room purification project is used in a large number of applications, planting such as the manufacture of items in the body, surgical procedures, including transplants, the manufacture of the integrator, the isolation of those who are particularly sensitive to bacterial infections of the patient's isolation treatment, for example, such as the isolation of the patient's bone marrow transplantation post-operative treatment.
The cleanliness level of the clean room is actually that the smaller the value, the higher the level of purification, the higher the cleanliness, the higher the cost. Hundred level clean room means that the air cleanliness is 100 clean room, that is, the workshop particles per cubic meter control within 100, comparable to the degree of cleanliness requirements of the operating room.
