The Kjeldahl method is a classical method for measuring nitrogen, and the Kjeldahl nitrogen analyzer is a special instrument for determining nitrogen based on the Kjeldahl method. Currently, Kjeldahl nitrogen analyzer has been widely used with the development of the industry. It has played an important role in the testing of soils, foods, agricultural products, feeds, and other nitrogen-containing compounds. When the Kjeldahl method is used to determine the sample, it will undergo sample digestion - sample distillation separation - titration analysis of the three processes, and in the process of sample digestion will produce a lot of acid mist, which will cause serious environmental pollution, Damage to facilities will affect the health of operators. Therefore, modern Kjeldahl analyzers need to solve these problems. How does the Kjeldahl nitrogen analyzer achieve pollution-free emissions?
The Kjeldahl nitrogen analyzer has been able to achieve pollution-free emissions because the instrument is equipped with an exhaust gas collection device and an acid-neutralizer that can achieve the collection, neutralization, and filtration of the acid mist. The exhaust gas collection device will mainly be used during the digestion process. The large amount of acid mist generated is collected, and the neutralization of acid and alkali is responsible for the treatment of acid mist. The device is mainly composed of a secondary filter. The first stage completes the neutralization and filtration of the acid mist with the corresponding concentration of alkali solution. And enter the second stage, the second stage uses distilled water, continue to filter the residual gas discharged into the first stage, after the secondary filtration of the gas can be ruled out. Through verification, the neutralized filtered gas is a neutral gas, which will not cause any harm to the environment and facilities, thus ultimately achieving pollution-free emissions.
At present, the safety and stability of the Kjeldahl nitrogen analyzer are very high, which not only ensures the safety of the operators during the test, but also avoids the environmental pollution during the test process, compared with the traditional Kjeldahl method. The use of the Kjeldahl nitrogen analyzer to carry out the determination test has the characteristics of convenience, speed, accuracy, etc., and can meet the requirements of modern sample measurement. Therefore, it is highly welcomed by industry personnel.
The main function of printing thickener is to provide good rheological properties. It transfers the sizes or colour sizes on printing screen and roller to the fabric to combine dyes with fibers to ensure the clear outline of printing patterns. The pattern is clear, the color is bright and even. When the dye is fixed, the reaction products and residues can be easily removed in the downstream process, which makes the fabric feel soft. It can be seen that Printing Thickeners play an important role in the printing industry.
