Application of Moisture Analyzer With the development of scientific research and the development of production technology, the quantitative analysis of moisture has been listed as one of the basic items of physical and chemical analysis of various substances, and it is an important quality indicator of various substances.
Different requirements for the determination of moisture were proposed according to the different moisture contents in the different types of samples. Moisture measurement can be industrial production control analysis, or the signing of the quality of industrial and agricultural products; moisture can be measured from tons of product, and only a few microliters of test solution can be used for moisture analysis in the laboratory; A constant moisture analysis of several to several tens of tens of thousands of water, or a trace moisture analysis with a water content of only one millionth or less.
These instruments are simple, sensitive, and reproducible. They can measure continuously and automatically display data. Foreign moisture analyzers are expensive and are unsustainable for some domestic laboratories and companies. In recent years, many domestic instrument manufacturers have strengthened the research and practice of moisture analyzers, and have achieved very significant benefits, bringing the various technologies of domestic moisture analyzers closer to international standards and meeting the needs of general laboratories and enterprises. Classical moisture analysis methods have been gradually replaced by various moisture analysis methods.
Moisture Analyzer Classification and Application Ranges Moisture analysis methods can generally be divided into two major categories, namely physical analysis and chemical analysis.
Chemical analysis moisture analyzers include: Karl Fischer moisture analyzer, Coulomb moisture analyzer, and dew point moisture analyzer.
Karl Fischer is a classical method, also known as trace moisture analyzer, which is mainly used for the detection of samples with low moisture content. After improvements in recent years, it has greatly improved the accuracy and expanded the measurement range. Domestic Karl Fischer moisture analyzers include Shanghai Science and Technology Instrument Co., Ltd., Haidian Chaosheng, Pioneer Weifeng, and Jiangsu Jianghuan Analytical Instrument Co., Ltd.
The dew-point moisture analyzer is easy to operate, the instrument is not complicated, and the measured results are generally satisfactory. It is often used for the determination of trace moisture in permanent gas. However, this method interferes more. Some cold-changeable gases, especially at higher concentrations, interfere with condensation than water vapor.
Coulomb moisture meters are often used to determine the moisture content of gases. This method is easy to operate, quick to respond, and especially suitable for the determination of trace moisture in gases. If you use ordinary chemical methods, it is very difficult. However, electrolytic methods are not suitable for the determination of alkaline substances or conjugated diolefins. Manufacturers include Chengdu Instrument Factory, Jiangsu Jianghuan, Daqing Rishang and others.
The moisture analyzer of the physical analysis method includes: an infrared moisture meter, a halogen moisture meter, and a microwave moisture meter.
Infrared (Halogen) Moisture Analyzer is easy to operate, less time-consuming and accurate, so the infrared moisture meter can be widely used in all industries that need to measure moisture quickly, such as medicine, food, feed, seeds, rapeseed, dehydrated vegetables, tobacco , Chemicals, tea, food, meat and textiles, agriculture, forestry, paper, rubber, plastics, textiles and other industries in the laboratory and production process. . Domestic infrared (halogen) moisture analyzer is mainly Shenzhen Guanya Electronic Technology Co., Ltd.
The microwave moisture analyzer uses a microwave field to dry the sample, which accelerates the drying process, has a short measurement time, is easy to operate, and has high accuracy, and is suitable for determination of moisture in petroleum, kerosene, and other liquid samples. Domestic manufacturers include Changsha Youxin Company.
O Ring, Rubber O ring: An O-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.
O ring are installed in the groove, moderate compression section for type O sealing ring (circle). Because of its manufacturing cost is not high, convenient installation and therefore has been widely used in the sealing industry.
O-ring mainly used for fluid (such as: water, oil, air, chemical solvents, chemicals, etc.) and sealing the gap between a static long-term use temperature of -60 ℃ to 220 ℃.. Varies on material, the use of static pressure is less than 20MPa. Sometimes for dynamic, dynamic pressure when using less than 5MPa. And semiconductor vacuum seal.
An o-ring technically is also a gasket but it's shape and the material it is made from differs from most gaskets. The biggest difference between the two is o-rings are almost exclusively used for very high pressure applications such as hydraulics where a regular cork, paper or rubber gasket would fail.
Gasket is also called as static seal. It is a mechanical element use to prevent the leakage of fluid between the two components which are static or doesn't have relative motion. While Oil Seal also called as dynamic seal is use to prevent leakage of fluid between two components having relative rotary or sliding motion.
A gasket is primarily used to seal two mating surfaces. It prevents leakage of fluids. Washers on the other hand are used primarily to spread pressure evenly, and are used in places of high vibration.
A washer is a thin plate (typically disk-shaped) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a screw or nut.
Our Factory used materials: Nitrile Rubber, Silicone Rubber, Fluorine Rubber, EPDM Rubber, Acrylic Resin, Tetrapropanate Fluorine Rubber, Chloroprene Rubber, Epichlorohydrin Rubber, Fluoro Silicone Rubber, Hydrogenated Nitrile Rubber, Butyl Rubber, Natural Rubber, Polyurethane Rubber, Styrene Butadiene Rubber, PE, PTFE and so on.
