Importance and selection of special hinge for anti-corrosion fume hood
With the development of science and technology and the improvement of experimental requirements, the requirements of laboratory furniture are getting higher and higher. As one of the important safety protection equipment in the laboratory, the performance of fume hood directly affects the safety and health of users. Among them, the special hinge for anti-corrosion fume hood is an important accessory, and its quality is directly related to the service life and safety of the whole fume hood.
First, the importance of special hinge for anti-corrosion fume hood
1. Ensure the normal operation of the fume hood: Hinge is the key component connecting the door panel and other parts of the fume hood. Frequent opening and closing of the door in daily use will cause the hinge to be worn or damaged, so high-quality hinges can ensure the fume hood to work stably and reliably for a long time.
2. Improve the safety of the laboratory environment: corrosive chemicals can easily lead to rust or serious corrosion of hinges made of ordinary materials, which not only affects the appearance, but also may cause harm to users; The hinge made of high-quality anti-corrosion materials can effectively avoid such problems, improve the overall structural stability and prolong the service life.
3. Compliance with relevant specifications and standards: According to the technical conditions of GB/T148692017 experimental platform, there are clear requirements for various facilities in the laboratory, including but not limited to functional indicators such as "acid and alkali resistance" and "moistureproof and waterproof". Therefore, only products that meet the specified requirements can achieve the expected results and facilitate the later maintenance and management.
Second, how to choose the appropriate hinge for anti-corrosion fume hood?
1. Material selection:
(1) Stainless steel series: it has good heat resistance and chemical corrosion resistance;
(2) Copper alloys: they have good electrical conductivity and wear resistance, and are suitable for special occasions such as strong oxidants;
(3) Engineering plastics/composites: light in weight but high in strength, with good chemical stability and insulation properties, which are suitable for various application scenarios.
2. Design details:
Pay attention to the following points when purchasing:
(1) Whether it is easy to install and disassemble to facilitate later cleaning and maintenance;
(2) Whether the bearing capacity meets the actual needs (for example, large-size glass windows are heavier);
(3) The smoothness of opening and closing and the existence of damping devices need to be carefully checked and verified.
3. Reference brand word-of-mouth evaluation:
It is also a feasible way to judge the quality by knowing the feedback of products produced by various manufacturers in the market.
In a word, when selecting the hinge for anti-corrosion fume hood, we should comprehensively consider many factors to make a decision, so as to ensure that we finally choose the ideal one that meets the budget and functional requirements!
