Nitrogen purity indicators for various industries
The electronics industry（≥99.9%）
Generally used for packaging, sintering, annealing, reduction, storage, etc. of electronic products. Mainly used in industries such as wave soldering, reflow soldering, crystal, piezoelectric, electronic ceramics, electronic copper strips, batteries, and electronic alloy materials. So the purity requirements vary depending on the purpose, usually requiring no less than 99.9%, some use 99.99% purity, and some even use nitrogen purification equipment to obtain high-quality nitrogen with a purity greater than 99.9995% and a dew point lower than -65 ℃.
Metallurgical and metal processing industries (≥ 99.999%)
Used for annealing protection atmosphere, sintering protection atmosphere, nitriding treatment, furnace cleaning and blowing gas, etc. Applied in metal heat treatment, powder metallurgy, magnetic materials, copper processing, metal wire mesh, galvanized wire, semiconductor, powder reduction and other fields. By producing nitrogen with a purity greater than 99.9% and using it in combination with nitrogen purification equipment, high-quality nitrogen with a purity greater than 99.9995% and a dew point lower than -65 ℃ is produced.
Food and pharmaceutical industries (≥ 99.5 or 99.9%)
High quality nitrogen gas is obtained through processes such as sterilization, dust removal, and water removal, meeting the special requirements of the industry. Mainly used in food packaging, food preservation, pharmaceutical packaging, pharmaceutical ventilation, and pharmaceutical conveying atmosphere. By producing nitrogen with a purity of 99.5% or 99.9%.
Chemical and new materials industries (generally requiring nitrogen purity ≥ 98%)
Nitrogen in the chemical and new materials industries is mainly used for chemical feed gas, pipeline blowing, atmosphere replacement, protective atmosphere, product transportation, etc. Mainly used in industries such as chemical, spandex, rubber, plastics, tires, polyurethane, biotechnology, intermediates, etc. The purity is required to be no less than 98%.
Other industry sectors of use
It is also used in other fields such as coal, oil, and oil transportation. With the progress of technology and the development of society, the use of nitrogen is also increasing. On site gas production has gradually replaced traditional nitrogen supply methods such as liquid nitrogen evaporation and bottled nitrogen due to its advantages of low investment, low operating cost, and convenient use.
Nitrogen generator rental - on-site nitrogen production
The PSA pressure swing adsorption nitrogen generator, as a major equipment for on-site nitrogen production, has the characteristics of economy, efficiency, time-saving, and simplicity. It does not require the purchase of finished nitrogen gas and can directly separate nitrogen gas from the air, resulting in low operating costs. Moreover, the pressure swing adsorption nitrogen production technology can adjust the purity and flow rate of nitrogen according to the specific needs of the site, and has significant advantages compared to traditional bottled nitrogen.
The benefits of on-site nitrogen production:
1. Time saving: By on-site nitrogen production, you can eliminate delays and logistics risks associated with purchasing liquid nitrogen, thereby obtaining a continuous supply of nitrogen.
2. Easy to install: Easy to install, use, and maintain.
3. Cost control: The cost of bulk nitrogen typically depends on the duration of the procurement contract. When producing nitrogen on-site, you can produce as much nitrogen as you need.
4. Overall solution: Customized solutions to meet the specific needs of the project. We not only provide on-site nitrogen production equipment, but also offer a complete set of solutions.
5. Safety first: For operators and end-users, it is safer to control the time and method of using nitrogen, without waste or leakage.
6. Focusing on core business: We can provide 24 x 7 all-weather service support, so you can focus on your core business.
