Importance and selection of special seal for box lock
In the industrial field, sealing is an important index for some specific equipment and devices. Among them, the box lock is one of the products that are frequently used in daily life, and its sealing performance is directly related to the safety and preservation effect of articles. The key component to ensure the good sealing performance of the box lock is the special seal for the box lock.
I. Function and Importance of Special Seal for Box Lock
1. Waterproof and dustproof function
The special seal for box lock can effectively prevent impurities such as rain and dust from entering the lock body, thus protecting the lock from the external environment. This is especially important for outdoor bags or boxes for storing precision instruments and valuables.
2. Improve durability
Good sealing performance is helpful to prolong the service life of the box lock. Because when moisture and corrosive substances in the air enter the lock body, the metal parts will rust and be damaged; And long-term exposure to humid environment will also accelerate the aging process of electronic components. Therefore, this kind of problem can be avoided by improving the sealing performance of the whole box lock.
Step 3 increase security
In addition, in some special occasions (such as military use), luggage needs to have strong impact resistance to ensure that the contents are safely transported to the destination without damage. At this time, if the box lock is poorly sealed, it may lead to unlocking failure due to collision and other reasons, which will affect the progress of task completion and even cause irreparable losses.
4. Improve the user experience.
Last but not least, a special sealing ring with reasonable design and high quality can make users feel more comfortable feel and more assured psychological expectation-after all, no one wants their suitcase or toolbox to be opened easily, right?
Second, how to choose the right special seal for box lock?
In view of the above requirements, the following will introduce several common material types and their scope of application:
1.PVC material:
This is a low-cost plastic product which is also common in the civil market. It has good flexibility and weather resistance, and can maintain a certain elasticity in low temperature environment. However, due to the toxicity of PVC itself (especially the release of harmful gases under heating conditions), it is recommended to use it only in non-food contact applications.
2.TPE/TPR/TPO thermoplastic elastomer:
This kind of composite material has the advantages of traditional rubber and synthetic resin: high strength, strong resilience and difficult deformation make them very suitable for making small parts with strict specifications and sizes; In addition, because it does not contain halogen, it will not produce toxic smoke to pollute the environment during combustion.
3.Silicone silica gel:
As we all know, silica gel is famous all over the world for its unique chemical stability-it can withstand extreme pressure.
The terminal temperature changes (60°C to+200 C) and shows excellent resistance to almost all organic solvents; In addition, this raw material has excellent electrical insulation and low permeability, so it is especially suitable for medical and health care industries.
Third, summary
To sum up, we can see that there are many technical details behind a seemingly simple and ordinary small object! Therefore, before purchasing or customizing the corresponding models and specifications, it is best to know clearly the specific standards you need to achieve in order to make a correct decision.
