涂布无尘车间在生产过程中，由于涉及到高分子材料、化学制品等，极易产生静电。静电会对产品和生产环境造成诸多不良影响，如吸引灰尘、吸附粒子等，严重影响产品质量。因此，在涂布无尘车间内安装静电消除装置非常必要。

一、涂布无尘车间静电的产生及危害

1. 静电的产生

在涂布无尘车间内，静电主要来源于以下几个方面：

（1）摩擦：生产过程中，物体之间的摩擦产生静电。例如，塑料制品、化纤材料在加工过程中，由于摩擦而产生静电。

（2）剥离：在涂布过程中，涂料与载体之间的剥离产生静电。

（3）接触：物体在接触过程中，由于电荷的不平衡而产生静电。

（4）感应：在高压电场作用下，物体表面产生静电。

2. 静电的危害

（1）吸引灰尘：静电会吸引空气中的灰尘、粒子，附着在产品表面，影响产品质量。

（2）电击：静电放电时，会产生电击现象，对生产和操作人员造成伤害。

（3）设备损坏：静电会对电子设备、仪器仪表等造成损坏，影响生产正常进行。

（4）火灾爆炸：在易燃易爆环境中，静电可能引发火灾或爆炸事故。

In the production process of the coating dust-free workshop, it is easy to generate static electricity due to the involvement of polymer materials, chemicals, etc. Static electricity will cause many adverse effects on products and production environments, such as attracting dust, adsorbing particles, etc., which will seriously affect product quality. Therefore, it is necessary to install a static elimination device in the coating clean room.

1. The generation and hazard of static electricity in the dust-free workshop

1. Generation of static electricity

In the coating dust-free workshop, static electricity mainly comes from the following aspects:

(1) Friction: During the production process, friction between objects generates static electricity. For example, during the processing of plastic products and chemical fiber materials, static electricity is generated due to friction.

(2) Peeling: During the coating process, the peeling between the coating and the carrier generates static electricity.

(3) Contact: During the contact process, static electricity is generated due to the imbalance of charge.

(4) Induction: Under the action of high-voltage electric field, static electricity is generated on the surface of the object.

2. Hazards of static electricity

(1) Attracting dust: static electricity will attract dust and particles in the air, attach to the surface of the product, and affect the quality of the product.

(2) Electric shock: When electrostatic discharge, electric shock will occur, causing injury to production and operators.

(3) Equipment damage: static electricity will cause damage to electronic equipment, instrumentation, etc., affecting the normal progress of production.

(4) Fire and explosion: In flammable and explosive environments, static electricity may cause fire or explosion accidents.

Second, the function and principle of static elimination device

1. Role

The static elimination device is mainly used to eliminate static electricity in the coating dust-free workshop in real time to prevent static electricity from causing adverse effects on production and the environment. Its main functions are as follows:

(1) Reduce the electrostatic electricity on the surface of the object and prevent the accumulation and discharge of static electricity.

(2) Eliminate static electricity in the air and reduce the impact of static electricity on the product.

(3) Protect production and operation personnel from static electricity.

2. Principle

Static elimination devices mainly achieve static elimination in the following ways:

(1) Air ionization: A large number of negative ions are generated through the ionization device, so that the positive ions and negative ions in the air are balanced and the static electricity is reduced

(2) Grounding: The object is connected to the ground through a wire, and the static electricity is introduced to the ground, thereby eliminating the static electricity.

(3) Static Eliminator: The electric field of the electrostatic eliminator is used to neutralize the charge on the surface of the object to achieve the purpose of eliminating static electricity.

3. Installation and application cases of static elimination device in coating dust-free workshop

1. Installation

The installation location of the static elimination device in the coating dust-free workshop is usually as follows:

(1) Entrance: Install an electrostatic elimination device at the entrance of the workshop to eliminate static electricity for personnel and items entering the workshop.

(2) Production equipment: install static elimination devices in key parts such as coating equipment and drying equipment.

(3) Air purification system: install static elimination device in the air purification system to reduce static electricity in the air.

2. Application cases

(1) A plastic products factory: a static elimination device is installed in the coating dust-free workshop, which effectively reduces the static electricity on the surface of the product and improves the product quality.

(2) A coating factory: a static elimination device is installed on the drying equipment on the coating production line to reduce the defects such as fish eyes and pitting on the surface of the coating film.

(3) An electronics factory: an electrostatic elimination device is installed in the coating dust-free workshop to protect electronic components from electrostatic damage and improve product yield.

Fourth, summary

It is necessary to install static elimination devices in the coating dust-free workshop, which can effectively reduce the impact of static electricity on production and the environment, improve product quality, and ensure the safety of production and operators. According to the existing information and project cases, it is suggested that the installation and application of static elimination devices should be fully considered in the design of the coating dust-free workshop, so as to create a good environment for production.
