The chromatograph is a device for chromatographic separation analysis. Including sample introduction system, detection system, record and data processing system, temperature control system and mobile phase control system. Modern chromatographs are characterized by their stability, sensitivity, versatility, and high degree of automation. Ion chromatography is an important chromatographic separation technology for the analysis of ionic compounds. It is widely used in the food, electronics, chemical, energy, and environmental fields and is a necessary analysis tool for quality control, environmental protection, and other related departments to obtain basic data. However, over the years, the domestic ion chromatograph market has been monopolized by foreign companies. Domestic ion chromatographs have a large gap with international standards. In particular, there are shortcomings or shortages in the production technology of chromatographic columns, suppressors and other major core components. The imported ion chromatograph is expensive and users can't afford it; the domestic ion chromatograph is unstable and the user dares not use it, which restricts the wide application of the ion chromatograph. Recently, the project of “Development and Industrialization of Multi-functional Ion Chromatographâ€, organized by the State Administration of Quality Supervision, Inspection and Quarantine Technology Development Center of Qingdao, Shandong Province, has been approved as a national special project for the development of major scientific instruments and equipment. Recently, the project of “Development and Industrialization of Multi-functional Ion Chromatograph†organized and organized by the State Administration of Quality Supervision, Inspection and Quarantine Technology Development Center of Qingdao, Shandong Province was approved as a national special project for the development of major scientific instruments and equipment. The special project adopts the joint management and organizational management model. There are 9 sub-tasks involving 8 production, research, and research cooperation units.
Ion chromatography is an important chromatographic separation technique for the analysis of ionic compounds. It has unique advantages in sample analysis and plays an irreplaceable role in gas chromatography and liquid chromatography. Ion chromatographs are widely used in the fields of food, electronics, chemical engineering, energy, and the environment. They are necessary analytical tools for quality control, environmental protection, and other related departments to obtain basic data. Therefore, ion chromatography has a huge demand and market in the fields of quality inspection, environmental protection, electronics, and energy. However, over the years, the domestic ion chromatograph market has been monopolized by foreign companies, and the gap between domestic ion chromatographs and the international level is large, especially in the production technology of chromatographic columns, suppressors and other major core components. The imported ion chromatograph is expensive and users can't afford it; the domestic ion chromatograph is unstable and the user dares not use it, which restricts the wide application of the ion chromatograph. The organization and implementation of the project “Development and Industrialization of Multi-functional Ion Chromatographs†aims to develop high-sensitivity, high-stability multi-functional ion chromatographs with independent innovation core technologies and achieve industrialization. The leading role of innovation in industrialization has important social and economic significance.
According to reports, the National Special Scientific Instruments and Equipment Development Special Project was established by the Ministry of Science and Technology and the Ministry of Finance in 2011 to support the development of major scientific instruments and equipment, and to improve the independent innovation capability and self-equipment level of China's scientific instruments and equipment, and to form a Characteristic, influential scientific instruments and equipment, service economy and social development.
The main function of the edge banding is to seal the cross-section of the board, so as to avoid the damage of the board and the adverse factors (mainly moisture) in the process of use and prevent the formaldehyde inside the board from volatilizing, and at the same time achieve the effect of beautiful decoration.
The product has the following main features: smooth surface, no blistering, no ribbing, moderate gloss, smooth surface and back surface, uniform thickness, uniform width, reasonable hardness, high elasticity, good quality, strong wear resistance, trimmed and sealed The color of the side and the side is close to the surface color, not whitish, good gloss, and the overall color of the finished furniture is coordinated.
The role of edge banding:
First, the edge banding has the function of blocking harmful gases such as formaldehyde
Good edge banding or multi-sided edge banding can reduce the amount of formaldehyde emission per unit time (ie, slow down the emission rate). It is worth noting that edge banding will not reduce the formaldehyde content of the board, but this has the advantage of edge banding. It can reduce the formaldehyde emission per unit time of unenvironmentally-friendly sheets to a level that is acceptable to humans and does not affect health.
Second, the role of beautifying furniture
Good edge banding has the effect of beautifying office furniture, but if it is to be beautiful, the requirements for edge banding will be higher. Not only must the edge banding and the end surface of the board be firmly and smoothly combined, but also that the edge banding must be combined with other The joints of the surfaces should not have defects such as bottoming, chipping, and large gaps, and the transition should be natural, smooth and smooth.
Third, extend the service life of office furniture
The precise edge sealing design of the board can prevent water or other liquids from entering the board, avoiding the expansion, deformation and breeding of bacteria on the desktop, thereby prolonging the service life of the office furniture, and the office furniture after the edge sealing treatment is also more expensive in terms of cleaning easy.
Fourth, avoid sharp edges and corners from hurting people's bodies
The general edge banding will use the dull edge banding design to smooth the corners of the table, thereby reducing the damage to the body by the sharp corners
