Introduction

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.

1. Basic characteristics of bis-(2-dimethylaminoethyl) ether

1.1 Chemical structure and properties

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

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.

1.2 Physical Properties

The physical properties of bis ethers are shown in the following table:

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.

2. The electrostatic elimination mechanism of bis-(2-dimethylaminoethyl) ether

2.1 Generation and harm of static electricity

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:

1. Friction-energizing: When two objects of different materials rub against each other, electrons will transfer from one object to another, resulting in an unbalanced charge.
2. Induction of power-up: When a charged object approaches a conductor, the charge inside the conductor will be redistributed, causing static electricity to occur on the surface of the conductor.
3. Contact and electricity: When two objects separate after contact, electrons will transfer from one object to another, resulting in an unbalanced charge.

The harm of static electricity to precision instruments is mainly reflected in the following aspects:

1. Data Error: Static electrostatic interference with the signal transmission of the instrument, resulting in inaccurate data acquisition.
2. Damage of equipment: Electrostatic discharge will generate a momentary high voltage, which may break down the electronic components of the instrument and cause damage to the equipment.
3. Dust adsorption: Static electricity will absorb dust in the air, affecting the cleanliness and working performance of the instrument.

2.2 Electrostatic elimination mechanism of bis ether

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:

1. Adhesive moisture: The amino groups in the bisether molecule can adsorb moisture in the air and form a conductive film.
2. Charge Neutralization: The conductive film can conduct charge on the surface of an object into the air, thereby neutralizing static electricity.
3. Sustainable Effect: Due to the low volatility of bis ethers, the conductive film can remain stable for a long time and continuously eliminate static electricity.

2.3 Comparison of bis ethers and other electrostatic eliminators

With other common static electricityCompared with eliminators, bis ethers have the following advantages:
