Application and maintenance of anti-corrosion hinge of anti-corrosion fume hood

In the laboratory environment, experimenters need to use various chemicals and reagents frequently to carry out experimental operations. These chemicals will produce harmful gases in the process of volatilization, which will cause corrosion to the equipment in the laboratory. In order to protect the safety of laboratory environment and the service life of instruments, a kind of special furniture-fume hood, which is specially designed for storing and handling chemicals and removing harmful gases, came into being. Among them, as one of the important accessories of fume hood, anti-corrosion hinge plays a vital role.

I. Function and Classification of Anticorrosive Hinges

1. Function: The anti-corrosion hinge is mainly used to connect the door panel of the fume hood with the frame structure, so as to ensure that the door body can be opened and closed smoothly and has good sealing performance; At the same time, it must have excellent corrosion resistance to resist corrosion from internal chemicals.

2. Classification: According to different materials, it can be divided into stainless steel hinges, plastic hinges and other types; According to the installation method, it can be divided into two forms: surface-mounted hinge (also known as exposed hinge) and hidden hinge.

Second, the material selection and its characteristics analysis

For the anti-corrosion hinge applied to fume hood, its material selection is very important. Common high-quality materials are as follows:

1. Stainless steel: It has good mechanical strength and oxidation resistance, is stable and reliable in acid and alkali environment, and is easy to clean and maintain.

2. ABS plastic: light and durable, strong water resistance, suitable for low-concentration acid-base solution contact occasions.

3. Coating metal alloy: A protective film is formed on the surface of ordinary steel by electroplating to improve the overall corrosion resistance.

Third, the installation considerations

The correct installation method is not only related to the normal use effect of the product, but also directly related to the safety and stability of the whole system:

1. Before fixing, check whether all parts are intact;

2. Adjust the appropriate opening angle according to the actual demand before fastening;

3. Pay attention to keep the crack of the door uniform, so as to prevent deflection or looseness;

4. Regularly check whether there is abnormal wear on the hinge joint, and replace the damaged parts in time to avoid affecting the performance of the whole machine;

Fourth, daily maintenance skills

Because this kind of product has been running in harsh environment for a long time, it is very necessary to clean and disinfect it effectively on a regular basis:

1. Use mild neutral detergent with soft cloth to gently wipe the surface to remove impurities such as dirt and dust;

2. For the parts that are difficult to clean, you can choose tools such as special cleaning solution or high-pressure air gun to assist in completing the task;

3. At ordinary times, it is necessary to pay attention to avoid the collision and scraping of hard objects so as not to damage the surface protective coating and thus reduce the durability index;

In a word, anti-corrosion hinge is an indispensable key component to ensure the normal operation of fume hood. Only by selecting products with suitable materials and following correct and standardized operation procedures can their service life be effectively extended and the expected purpose be achieved. In addition, in the daily management work, we should also strengthen the monitoring of its status, and take immediate measures to solve problems when found, so as to create a healthier and more comfortable working space for scientific researchers!
