Preparation of polishing resin HMB400 using ultrapure water

Ultra pure water, also known as UP water, refers to water with a resistivity of 18M Ω* cm (25 ℃). Apart from water molecules, this type of water has almost no impurities, bacteria, viruses, or other organic matter. Of course, it also does not contain the mineral trace elements required by the human body, that is, water that has almost removed all atoms except oxygen and hydrogen. It can be used for ultra pure materials (semiconductor component materials, nano fine ceramic materials, etc.).

In the electronics industry, ultrapure water is used in semiconductor manufacturing, circuit board manufacturing, display manufacturing, and other fields. Because ultrapure water has almost no ions and microorganisms, it can avoid corrosion and pollution of electronic components; Biotechnology and Life Sciences: Ultra pure water is commonly used in research laboratories for experiments and tests that require high-purity water, such as cell culture, DNA sequencing, and protein purification; Pharmaceutical industry: Ultra pure water is used in the pharmaceutical industry for drug manufacturing, injection manufacturing, and other fields. Because there are no microorganisms or harmful substances in ultra pure water, it can avoid contamination and impact on drugs.

The production process of ultrapure water generally involves sand filtration, ultrafiltration, membrane treatment EDI、 The resin treatment process is crucial for producing ultrapure water that meets the requirements for electronic chemical use.

Ultra pure water polishing mixed bed resin is recommended for use in two ion exchange single beds or mixed beds after reverse osmosis or polishing mixed beds in ultra pure water systems. It is a renewable mixed bed resin that can be well separated to achieve ideal regeneration effects due to its obvious color and particle size differences.
