Nitrogen used in the electronics industry is generally used in the encapsulation, sintering, annealing, reduction and storage of electronic products. Mainly used in wave soldering, reflow soldering, crystal, piezoelectricity, electronic ceramics, electronic copper tape, batteries, electronic alloy materials and other industries. So according to the different uses of the purity requirements have also changed, usually the requirements can not be less than 99.9%, there are 99.99% purity, and some will use nitrogen purification equipment to get the purity of more than 99.9995%, the dew point of less than -65 ℃ of high-quality nitrogen.
Metallurgy, metal processing industry (≥99.999%)
Used in annealing protective atmosphere, sintering protective atmosphere, nitriding treatment, furnace cleaning and blowing gas, etc. Used in metal heat treatment, powder metallurgy, magnetic materials, copper processing, wire mesh, galvanized wire, semiconductor, powder reduction and other fields. Through the production of nitrogen with purity greater than 99.9%, and through the joint use of nitrogen purification equipment, the purity of nitrogen is greater than 99.9995%, with a dew point of less than -65 ℃ high-quality nitrogen.
Food, pharmaceutical industry (≥99.5 or 99.9%)
Through sterilization, dust removal, water removal and other treatments, high quality nitrogen is obtained to meet the special requirements of the industry. Mainly used in food packaging, food preservation, pharmaceutical packaging, pharmaceutical replacement gas, pharmaceutical transportation atmosphere. By making nitrogen gas with purity of 99.5% or 99.9%.
Chemical industry, new material industry (generally want nitrogen purity ≥ 98%)
Nitrogen in chemical industry and new material industry is mainly used for chemical raw material gas, pipeline blowing, atmosphere replacement, protective atmosphere, product transportation and so on. Mainly used in chemical, spandex, rubber, plastic, tire, polyurethane, biotechnology, intermediates and other industries. The purity is not less than 98%.
Other industries
It is also used in other fields such as coal, petroleum and oil transportation. With the progress of science and technology and the development of society, the use of nitrogen in more and more fields, on-site gas production with its investment, low cost, easy to use and other advantages has gradually replaced the liquid nitrogen evaporation, bottled nitrogen and other traditional ways of nitrogen supply.
