In the food, fertilizer, soil, grain, chemical and many other industries, the detection of nitrogen is increasing, and we know that the detection of nitrogen or protein detection is one of the most cumbersome tests in chemical laboratories, although there are professions. Instruments such as nitrogen analyzers help, but many of these operations still need to be done manually. In order to improve efficiency and make the protein detection "quickly stable", a more automated automatic nitrogen analyzer came into being.
The use of an automatic nitrogen analyzer to detect protein content has five major advantages. The first is fast, the instrument is easy to use, simple to operate, high detection efficiency, can quickly obtain measurement results, greatly improving the efficiency of protein detection; second is accurate, automatic nitrogen analyzer sensitivity, precision, use of instruments The operation can reduce the manual error and obtain the true and accurate measurement result. The third is automatic. The traditional nitrogen analyzer is semi-automatic, the titration needs to be completed manually, and the automatic nitrogen analyzer realizes complete automation operation. The process does not require human intervention, which greatly reduces the labor cost of the whole experiment, and the measurement efficiency is several times higher than the traditional method. The fourth is environmental protection. The automatic nitrogen analyzer has an excellent exhaust gas recovery device, which can effectively prevent the exhaust gas from escaping and is safer. And environmental protection; the fifth is safety, the safety protection function of the automatic nitrogen analyzer is more perfect, and the safety of the operator is guaranteed.
The above are the five advantages of automatic nitrogen analyzer to detect protein content. To sum up, it can be said that the automatic nitrogen analyzer makes the protein detection "fast, accurate and stable". These advantages make the automatic nitrogen analyzer in food, medicine, The applications in cereals, dairy products, fertilizers, urea for vehicles, feed, plants, tobacco, etc. are more and more widely used, which not only meets the high-frequency protein testing experiments in all walks of life, but also ensures the detection effect through technological upgrading. , to provide support for the high quality development of various industries.
There are many grades of PVC. The viscosity or K value commonly used in the industry indicates the average molecular weight (or average degree of polymerization) of PVC, that is, the length of the PVC molecular chain, which determines the grade of the resin and the corresponding processing parameters. The molecular weight of the resin is related to the physical and mechanical properties of the product.
PVC Resin is a kind of non-crystalline linear polymer compound. The larger the relative molecular mass, the higher the viscosity, the higher the molecular weight, and the higher the tensile strength, impact strength, and elastic modulus of the product, but the flow of the resin melt Decline in sex and plasticity. The viscosity number is usually used to indicate the molecular weight of the polymer, and the polymer model is divided
PVC used to be the largest general-purpose plastic in the world, and it is widely used. It is widely used in construction materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc
SG3 (K-70, S1300): mostly used for soft products, hoses, wires and cables, films, shoe materials, toys, auto parts etc.
PVC RESIN SG3 has high purity, less fish eyes, easy to blister, high temperature resistance, insulation, soft product texture, etc. It is mainly used to produce soft products such as wires and cables, agricultural films, conveyor belts, and daily plastic products.
