With the rapid development of modern technology, precision instruments are being used in various fields more and more widely. Whether it is laboratories, medical equipment or industrial production, precision instruments play a crucial role. However, precision instruments have extremely high environmental requirements, especially their sensitivity to static electricity. Static electricity will not only affect the normal operation of the instrument, but may also lead to data errors and even equipment damage. Therefore, how to effectively eliminate static electricity has become an important issue in the protection of precision instruments.
Bis-(2-dimethylaminoethyl) ether (hereinafter referred to as “bis-ether”) has gradually attracted attention as an efficient electrostatic eliminator in recent years. This article will introduce in detail the electrostatic elimination ability, product parameters, application scenarios and actual effects of bis ethers, helping readers to fully understand the important role of this material in the protection of precision instruments.
The chemical formula of bis-(2-dimethylaminoethyl) ether is C8H18N2O, which is an ether compound containing two dimethylaminoethyl groups. Its molecular structure is as follows:
CH3
|
CH3-N-CH2-CH2-O-CH2-CH2-CH2-N-CH3
|
CH3
The molecular structure of the bis ether contains two amino groups, which makes it have strong polarity and can effectively absorb moisture in the air, thereby reducing the generation of static electricity. In addition, the molecular weight of the bis ether is moderate and has low volatility, and can maintain a stable electrostatic elimination effect for a long time.
The physical properties of bis ethers are shown in the following table:
Properties | value |
---|---|
Molecular Weight | 158.24 g/mol |
Boiling point | 210-215°C |
Density | 0.89 g/cm3 |
Flashpoint | 85°C |
Solution | Easy soluble in water, |
As can be seen from the table, bisethers have higher boiling points and lower volatilityThis makes it stable at room temperature and is not easy to volatilize losses. At the same time, bis ethers are easily soluble in water and organic solvents, making them easy to prepare and use in practical applications.
Static electrostatic is a phenomenon caused by the imbalance of the charges on the surface of the object. In the working environment of precision instruments, the production of static electricity mainly comes from the following aspects:
The harm of static electricity to precision instruments is mainly reflected in the following aspects:
The electrostatic elimination mechanism of bis ethers is mainly based on the amino groups in their molecular structure. The amino group has strong polarity and can adsorb moisture in the air to form a conductive film. This conductive film can effectively neutralize charge on the surface of the object, thereby eliminating static electricity.
Specifically, the electrostatic elimination process of bis ethers can be divided into the following steps:
With other common static electricityCompared with eliminators, bis ethers have the following advantages:
Electric Elimination Agent | Pros | Disadvantages |
---|---|---|
Bis-(2-dimethylaminoethyl)ether | The static electricity elimination effect is good and lasts for a long time | High cost |
Ion Fan | Fast static electricity removal | Continuous power supply is required, and the noise is high |
Antistatic spray | Easy to use | The effect lasts for a short time and is easy to volatile |
Antistatic cloth | Portable, easy to clean | The effect is limited, and it needs to be replaced frequently |
It can be seen from the table that bis ethers have obvious advantages in electrostatic elimination effect and duration. Although it is costly, it still has high application value in precision instrument protection.
The main function of the dustproof cover of precision instruments is to prevent dust, particulate matter and other pollutants from entering the instrument, and it also requires a certain ability to eliminate static electricity. Therefore, the design of the dust cover needs to meet the following requirements:
The main application of bis ether in precision instrument dustproof covers is as follows:
In practical applications, the electrostatic elimination effect of bis ether in the dustproof cover of precision instruments is significant. The following are some practical application cases:
