High Purity Chemical Concentration Water Supply System

High-purity chemicals are a key supporting material manufacturing of large-scale integrated circuits and oversized integrated circuits, mainly used for cleaning, etching, etching, and high-energy battery electrolytes, electronic components, high-end general chips, discrete, flat panel displays, Solar cells, photovoltaic glass and other fields. The purity and cleanliness of high-purity chemicals have a very important impact on the finished rate, electrical properties and reliability of the integrated circuit. High-purity chemicals have a variety of varieties, large amounts, high technical requirements, storage and use have time limit and have corrosive properties.

In the industries produced by integrated circuit chips and liquid crystal displays, various inorganic chemicals (mainly including various acids, alkali, salt, etc.) need to be delivered to process equipment through pipelines, these chemical solutions Harmful corrosive, flammable, explosive and volatility, etc. This type of tube is required to adopt a two-casing construction method, and the traditional dual cannula construction process is a hard tube construction method of a PP tube or a PVDF tube in a transparent PVC tube.

This process uses the construction method of transparent PVC tubes, that is, the pipeline system includes two-layer pipe inner and outer tubes, and the inner tube uses a soft pipe of a copolymer of tetrafluoroethylene and a total fluorine-based ethylene ether (divided by PFA / PVDF / ECTFE and other series), the inner tube is a pipe for transporting chemicals, and the outer tube uses a transparent PVC pipe to protect the pipe. The delivery pipeline specification is generally solder PFA pipe and its tubular members, pipes, and attachments, and the accessories, and the attachment. Connect to the device is usually connected to the flange.

High-purity chemical concentration water supply system composition: System generally consists of a receiving device provided between the exterior wall of the chemical, a chemical receiving storage tank, a supply device, and a chemical supply pipeline.

a. The chemical receiving device is provided in the chemical, and the exterior wall is provided with a receiving window, which directly receives the chemicals of the outdoor chemical tank car, and injects the drug storage tank.

b. Standardized Social Receiving Tanks, placed on the grounds of chemicals, store chemicals; c. The chemical supply device is placed in the chemical, supplies chemicals to the use of equipment.
