The industrial chain structure of liquid nitrogen generators in laboratories and industrial gases

　　Industrial natural gas has become one of the few industries that offer long-term growth trends and generate free cash flow for investors. Industrial natural gas companies sell their products as utility products to basic customers, not commodities. The industrial natural gas business model, as a special chemical, mitigates the cyclical and variable nature of the chemical industry, providing stable growth trends for revenue and returns.

　　Laboratory liquid nitrogen generatorFrom the perspective of the industry value chain, raw material air, transportation, and customers are the key points of the industrial gas industry value chain and are also key links in generating the industry's main profits.

　　The industrial chain structure of the laboratory liquid nitrogen generator is basically the same as that of the industrial gas industry chain. The industrial chain of the liquid nitrogen industry is air separation equipment, chemical product manufacturing, and liquid nitrogen container manufacturing, mainly used in downstream fields:

　　1. The metallurgy and metal processing industry is widely used in metal heat treatment, powder metallurgy, magnetic materials, copper processing, metal mesh, galvanized wire, semiconductors, powder reduction, etc., used for annealing protective gas, sintering protective gas, nitriding treatment, washing furnace, purge gas, etc. Some of these industries require nitrogen with a purity greater than 99.5%, while others require high-quality nitrogen with a purity greater than 99.9995% and a dew point below -65℃.

　　2. The chemical and new materials industry is mainly used for chemical raw material gases, pipeline purging, atmosphere replacement, protective atmosphere, product transportation, etc., in the chemical, spandex, rubber, plastics, tires, polyurethane, biotechnology, and intermediate industries. Many chemical industries do not have high requirements for nitrogen purity, and many have a purity higher than 98%.

　　3. The food and pharmaceutical industry is mainly used for food packaging, food preservation, pharmaceutical packaging, pharmaceutical gas replacement, and pharmaceutical transportation atmosphere. In order to meet the special requirements of the industry, it is usually necessary toLaboratory liquid nitrogen generatorcarry out sterilization, dust removal, and water treatment. The food industry does not have high requirements for nitrogen, and many nitrogen purities can reach more than 98%. The pharmaceutical industry usually requires nitrogen with a purity of 99.9%. When the amount of nitrogen used in the food industry is small, membrane separation is usually used to separate nitrogen; when the amount of nitrogen is large, pressure swing adsorption is usually used to produce nitrogen.

　　4. The electronics industry is mainly used for packaging, sintering, annealing, reduction, and storage of electronic products in industries such as wave soldering, reflow soldering, crystal soldering, piezoelectric soldering, electronic ceramics, electronic copper strips, batteries, and electronic alloy materials. Generally speaking, the electronics industry requires nitrogen with a purity of 99.9% or 99.999% or more.

　　The key raw materials for industrial gases are air separation gases and primary chemical raw materials. Key raw materials come from a very wide range, and the market supply is sufficient, making it easier to obtain from relevant raw material manufacturers. Industrial gas containers are used repeatedly for a long time, so the cost of industrial gas is relatively low, and the Price fluctuations have little impact on the industry. Key companies in the industry adjust other customers' Product Sales Prices according to raw material fluctuations, reducing the adverse impact on the company's profit level.
