The semiconductor industry has extremely high requirements for compressed air, which is usually classified according to its purity, dryness, oil content and other indicators. The classification of semiconductor compressed air is generally as follows:
| Grade | temperament (non-moisture) content | moisture content | oil content | scope of application |
|---|---|---|---|---|
| changman Level | ≥ 99.995% | ≤5mg/m³ | ≤0.003mg/m³ | it is suitable for the most sensitive aspects of semiconductor production, such as lithography machines, scanning electron microscopes and other high-tech manufacturing equipment. |
| Ultra-clean level | ≥ 99.99% | ≤10mg/m³ | ≤0.01mg/m³ | suitable for various aspects of semiconductor production, such as wet process, wafer cleaning, etc. |
| Net grade | ≥ 99.9% | ≤20mg/m³ | ≤0.1mg/m³ | suitable for most aspects of semiconductor production, such as chemical vapor deposition, dry process, etc. |
| Clean level | ≥ 99.5% | ≤50mg/m³ | ≤0.5mg/m³ | suitable for some semiconductor production links, such as oxidation furnace, annealing furnace, etc. |
| Protection level | ≥ 98% | ≤100mg/m³ | ≤1mg/m³ | suitable for non-critical aspects of semiconductor production, such as test equipment, auxiliary equipment, etc. |
| Industrial Grade | ≥ 95% | ≤500mg/m³ | ≤5mg/m³ | it is suitable for equipment other than semiconductor production, such as ordinary mechanical equipment, factory compressed air, etc. |
| Atmospheric Grade | ≥ 90% | ≤1000mg/m³ | ≤10mg/m³ | suitable for some general strong equipment, such as oil drilling, some fully enclosed thermostat, etc. |
These grades are designed to meet the stringent requirements of different semiconductor production processes on the quality of compressed air. In actual production, the higher the level of compressed air, the higher the production cost. Therefore, under the premise of ensuring the quality of the process, low-grade compressed air should be used as much as possible to reduce production costs. Compressed air grade standard of semiconductor plays a vital role in semiconductor production, which plays an important role in ensuring the stability of production process and improving product quality.
When discussing whether the screw air compressor uses frequency conversion technology better, the water-lubricated screw air compressor produced by Shanghai Granklin Group provides us with a powerful answer. The application of frequency conversion technology in screw air compressor is undoubtedly an important technological innovation.
The technical application specification of oil-free air in the air separation industry As the core field of industrial gas supply, the air separation industry has strict requirements on the quality of compressed air. Oil-free air technology provides a stable operation of air separation plants by eliminating oil contamination in compressed air.
Screw air compressor, as an important gas equipment, is used in various industries. It can be used as a power source to provide enterprises with compressed gas required for production, and secondly, the gas can also be used for refrigeration and separation, and the application is diverse. Due to the use of different occasions on
The new air compressor can be put into use after installation, after running in the atmospheric environment for a period of time, the tiny particles in the air continue to accumulate, into the air and oil circuit filter, will be blocked, affecting the air
Scroll compressor and screw compressor, the two can be described as the compressor in the world of "gentle gentleman" and "tough warrior". They have their own unique charm, let us explore their differences.
In the pharmaceutical industry, air compressors play a crucial role. It is mainly used to power pharmaceutical equipment and participate in multiple key steps in the pharmaceutical production process. Specifically, the use of air compressors in pharmaceutical plants includes, but is not limited to, the use of air compressors in pharmaceutical plants.
The formula for calculating the oil content of air compressors in ppm(parts per million, parts per million) is not directly given because it involves the mass content of lubricating oil in unit volume of air. However, we can understand this plan through some indirect methods or transformation relationships.
The relationship between air compressor power and pressure and air volume can be summarized from the following aspects: The relationship between power and pressure: There is a certain relationship between the power and pressure of the air compressor. Under normal circumstances, the greater the power of the air compressor, the pressure that can be generated
When the air compressor cannot be started again after the air compressor is stopped, it may be caused by various reasons. The following are some common reasons and corresponding solutions: Power problem: Check whether the power supply is normal, and confirm the air pressure
