In the electronics industry, compressed air plays an important role, but it also needs to meet certain quality requirements, including the following aspects:
compressed air must be dry and dust-free: In the production process of electronic products, tiny dust particles may have a negative impact on the performance of the product. Therefore, compressed air must be efficiently filtered to ensure that it is dust-free. In addition, due to the sensitivity of electronic products to humidity, compressed air also needs to be fully dried.
Low oil content in compressed air: In the production of electronic products, if the compressed air contains oil, it will not only affect the product quality, but may also cause the failure of production equipment. Therefore, the oil content of compressed air needs to be strictly controlled.
Pressure stability: The electronics industry has certain requirements for the pressure of compressed air, and it is necessary to ensure the stability of the pressure to prevent problems in the production process.
Specifically, some advanced electronic industry applications may need to use compressed air of 2-1-1 grade under ISO8573-1 standards, I .e. compressed air is below dew point temperature -20 ℃, dust particle size is not more than 0.1um, oil content is not more than 0.01 mg/m & sup3; and other standards. In some semiconductor, chip and other industries, it may be necessary to use more stringent compressed air quality levels, such as oil-free compressed air.
In order to meet these standards, the electronics industry usually installs various types of purification devices in compressed air systems, such as pre-air storage tanks, post-air storage tanks, precision filters (pre-filtration, pre-filtration and fine filtration) and dryers. Through the combination of these purification devices, the impurities in the compressed air, such as oil, moisture, solid particles, etc., can be effectively removed to ensure the purity and stability of the compressed air, so as to meet the high-quality requirements of the electronics industry for compressed air.
Nitrogen in the semiconductor factory is bodyguards, cleaners, porters and air conditioners, while the water-lubricated oil-free screw air compressor is the source that provides clean raw materials for the nitrogen machine. The source is not clean, and the back is completely useless.
The air pressure range of the plant usually depends on the specific application requirements. Generally speaking, the output pressure range of industrial air compressors is between 5~13 bar (that is, 500~1300 kPa or 72.5~188.5 psi), because most industrial applications, such as pneumatic tools and machines
Oil-free air compressors are widely used in many industries and fields, mainly due to their ability to provide high-quality, high-purity compressed air. The following are some of the main industries and fields where oil-free air compressors are applicable: Medical and health field: Because oil-free air compressors can
Common terms related to air compressors include: Nominal volume flow: refers to the volume of gas discharged by the air compressor per unit time under a certain exhaust pressure. Pressure: refers to the highest pressure of the air compressor discharge gas, the commonly used working pressure unit is bar or Mpa
Professional instructions on the output pressure of air compressors in large factories The output pressure of air compressors in large factories shall be comprehensively determined according to the production process, equipment characteristics and safety specifications, and there is no globally unified fixed value. Now from the technical standards, industry practice and optimization direction to provide
If the air compressor does not change the filter element for one year, the following results may be caused: Filter element blockage: Over time, the empty filter element will accumulate a large amount of dust, particles and other impurities, resulting in a decrease in its filtering effect or even complete blockage. Water filter may also be due to water
When choosing a permanent magnet inverter screw air compressor, users should consider a number of factors, including brand reputation, product quality, technical strength, after-sales service and cost performance. Although there are many brands and products to choose from in the market, the following suggestions or
Will high voltage cause the air compressor not to start automatically? Yes, too high voltage may cause the air compressor to fail to start automatically. Air compressor in the design has its rated operating voltage range, when the actual voltage exceeds this range, may lead to empty
Compressed air is widely used in the lithium battery industry and is a key element to ensure production quality and efficiency. The following is a detailed analysis of its core application scenarios and technical requirements: 1. electrode material preparation stage airflow crushing and classification function: driving airflow mill will be positive (such as NC
The amount of air supplied by a compressor is conceptually closely related to its output, but strictly speaking, they are not identical. Air supply usually refers to the volume or flow of compressed air that the compressor can provide per unit of time, which is a measure of compressor performance.
