Foamed electrical cabinet sealing strips are widely used in sealing industries such as electrical and electronic, lighting fixtures, chemical plants, industrial equipment, and automobiles. Their key functions are moisture-proof, anti fouling, shock absorption, and noise reduction. At present, there are many types of foam sealing strips on the market, how can we choose high-quality sealing strips? You may refer to the following two practices.
1、 Smell the odor
Take a sniff to see if it has a strong odor. High quality foam sealing strips are made of cost-effective raw materials and will not have a significant odor. If you smell something unusual, don't choose.
2、 Look at the surface
Wrap the sealing strip of the electrical cabinet tightly around the aluminum material and expose it to sunlight for a while. Check if there is any damage or discoloration in the area where the surface of the aluminum material comes into contact with the sealing strip. At the same time, check if there is any yellowing of dust on the surface of the sealing strip. If these phenomena occur, it indicates that the sealing strip is not good enough.
In summary, when selecting foam sealing strips, it is necessary to choose a cost-effective and better sealing strip to ensure good performance indicators. Do not choose counterfeit or inferior products to reduce costs.
Sealing strip of electrical cabinet
How many methods can machine cabinet sealing strips be connected?
But many friends know that this mechanical equipment sealing strip product has a wide range of uses. In order to integrate into this special natural environment, sometimes it is necessary to connect the entire piece together to form a ring, and then carry out practical effects. The following are some methods that come into contact. Do you know how to connect? Firstly, it is necessary to use strong adhesive. If it is of this type, whether it is foam or plastic, it can be connected with oily adhesive in any form.
If the strength is relatively strong, then if it is made of silicone foam, a special strong adhesive can also be used, but this strength is likely to be relatively weak. In situations where the specified level is not too high, it can be selectively applied, followed by mechanical equipment sealing strips that can also be hot melt connected. Whether it is silicone or polyethylene, hot melt can be used for this. If the strength and original adhesive are basically the same, the basic principle is that this continuous high temperature can connect them together.
So let's take a look at the sealing strip of the mechanical equipment and install an O-ring after connection, which is convenient for assembly and use on the equipment. If there is no connection, manual laser cutting can be used, and then it can be connected again to continuously melt at high temperature, which has a good pre immersion effect. This connection usually depends on the natural environment and the state of this operation method, and it is also very convenient to repair. Let's take a look again and see if there are any other ways.
The sealing strip of the electrical cabinet can also be classified based on the cross-sectional method and the characteristics of its application location. After sealing it tightly, it is not easy to open and has a very good waterproof sealing effect, as well as sound insulation and noise reduction. Although it may seem like a very small thing, such a small character cannot be ignored. By using this newly created raw material for sealing strips, you can understand that you should choose the ones with advantages and not the ones with inferior quality.
