Discussion on door hinge of corrosion-resistant fume hood

With the rapid development of science and technology and the continuous progress of industrial production, the design, manufacture and use of laboratory equipment pay more and more attention to safety and stability.. Among them, fume hood, as an important laboratory furniture, plays an irreplaceable role in protecting the health of experimenters and improving experimental efficiency. As an indispensable small part in the fume hood, the door hinge plays an important role in ensuring the realization of the overall function of the fume hood.

First, the basic function of the door hinge

Fume hood is a kind of professional equipment used to remove harmful gases, dust and other substances. Its working principle is to draw toxic gases from the operating area through a fan, and then filter them to the outside. In order to facilitate the experimenters to carry out various experimental operations, glass windows or door panels are usually set in front of the fume hood to ensure good observation field and convenient operation. At this time, it is necessary to use the door hinge to connect these movable parts with the fixed structure. Therefore, a door hinge with good performance and reliable quality is very important to improve the safety level of the whole fume hood.

Second, the necessity of corrosion resistance

Because of the complex and changeable laboratory environment, we often come into contact with acid-base solutions and other chemical reagents with strong corrosive properties. If the materials used do not have strong enough corrosion resistance, they are likely to be damaged or even failed due to long-term contact. This will not only affect the normal workflow, but also bring potential risks to users. Therefore, it is particularly important to choose a door hinge with excellent corrosion resistance.

Third, how to choose a suitable corrosion-resistant door hinge?

1. Material selection: Generally speaking, stainless steel is widely used to make such products because of its excellent comprehensive performance (such as high strength and good wear resistance); In addition, some special alloys can also be customized according to specific needs.

2. Surface treatment technology: the anticorrosion effect can be further enhanced by electroplating and plastic spraying on the metal surface;

3. Sealing design: non-metallic components such as rubber ring or silicone gasket are used for sealing, which effectively prevents external media from invading the internal mechanism and causing rust and other problems;

4. Structural optimization: Considering that there may be frequent opening and closing in practical application scenarios, it is necessary to try to avoid dead angle areas where moisture or impurities are easy to accumulate, so as to reduce the possibility of corrosion;

5. Consideration of brand reputation: Choosing well-known brands and understanding the feedback information from users can effectively avoid the subsequent troubles caused by quality problems.

To sum up, the importance of corrosion-resistant fume hood door hinge is self-evident. It is directly related to the personal safety of experimenters and the accuracy of experimental results. Therefore, in our daily work, we should attach great importance to the selection and procurement of related accessories, and strive to achieve the best cost-effective solution!
