Ultrapure water, also known as up water, refers to water with a resistivity of 18 m*cm (25). In addition to water molecules, there are almost no impurities, no bacteria, viruses, chlorinated dioxins and other organic matter, and of course, there are no minerals and trace elements required by the human body, that is, water that almost removes all atoms except oxygen and hydrogen. It can be used in the preparation process of ultra-pure materials (semiconductor component materials, nano-fine ceramic materials, etc.) using distillation, deionization, reverse osmosis technology or other appropriate supercritical fine technology.
The resin of the polishing mixed bed cannot be recycled and reused. The polishing mixed bed, also known as the disposable mixed bed, is generally used at the end of the process to further improve the quality of the produced water. In order to obtain a conductivity of 0055 s cm (resistivity 18.)2 m ·cm) theoretical pure water, after the ordinary mixed bed or EDI water purification equipment, the polishing mixed bed is usually installed for the final finishing.
Ultrapure water can be used in the following areas:
1) Electronics, electric power, electroplating, lighting appliances, laboratory, food, papermaking, daily chemicals, building materials, painting, batteries, laboratory, biology, pharmaceutical, petroleum, chemical, steel, glass and other fields.
2) Chemical process water, chemical agents, cosmetics, etc.
3) Production processes of monocrystalline silicon, semiconductor wafer cutting and manufacturing, semiconductor chips, semiconductor packaging, lead cabinets, integrated circuits, liquid crystal displays, conductive glass, picture tubes, circuit boards, optical communications, computer components, capacitor clean products and various components.
TULSIMER MB-1518 is a ready-to-use, pre-mixed, super regenerative polishing resin made from premium TULSIMER T-42(NS)H (strong acid cation exchange resin) and TULSIMER A-24 OH (strong alkali anion exchange resin) in a 1:1 ratio5 volume ratios are mixed. It is designed to produce ultra-high purity water. The cationic and anion exchange resins used in Tulsimer MB-1518 are made through a carefully developed process that uses a super regeneration process that prioritizes obtaining a pure product. This advanced manufacturing technology ensures that the quality of the resin is unmatched, making it the preferred choice for the preparation of ultrapure water.
