涂布无尘车间是如何做到在生产时无尘的？

涂布无尘车间是一种在生产过程中控制尘埃、微粒和其他污染物颗粒的环境，以确保产品质量和生产效率。在涂布工艺中，无尘车间对于产品的外观、性能和可靠性至关重要。本文将详细介绍涂布无尘车间是如何实现无尘环境的，以及其关键技术和措施。

一、无尘车间的定义及分类

无尘车间是指在室内环境中，通过空气过滤、尘埃控制、湿度和温度控制等措施，将空气中的尘埃和其他微粒浓度降低到一定程度，以满足特定生产工艺要求的洁净室。根据洁净度等级，无尘车间可以分为若干个级别，如ISO 1级、ISO 5级、ISO 10级等。其中，ISO 1级表示空气中的尘埃颗粒直径小于0.1μm，数量不超过100颗/立方厘米；ISO 10级表示空气中的尘埃颗粒直径小于1μm，数量不超过1000颗/立方厘米。

A dust-free workshop is an environment where dust, particulates and other pollutant particles are controlled during the production process to ensure product quality and production efficiency. In the coating process, a dust-free workshop is essential for the appearance, performance and reliability of the product. This paper will introduce in detail how to achieve a dust-free environment in coating dust-free workshop, as well as its key technologies and measures. A dust-free workshop refers to a clean room that reduces the concentration of dust and other particles in the air to a certain extent to meet the requirements of specific production processes through air filtration, dust control, humidity and temperature control and other measures in the indoor environment. According to the cleanliness level, the dust-free workshop can be divided into several levels, such as ISO level 1, ISO level 5, ISO level 10, etc. Among them, ISO 1 indicates that the diameter of dust particles in the air is less than 0.1μm, and the number is not more than 100 pieces/cubic centimeter; ISO level 10 indicates that dust particles in the air are less than 1μm in diameter and do not exceed 1,000 particles per cubic centimeter.

按理来讲，车间内的气流→初效过滤净化→空调→中效过滤净化→净化风柜送风→送风管道→高效送风口→吹入洁净室→带走尘埃细菌等颗粒→回风百叶窗→初效过滤净化，反复重复这个工作流程，就可以可达到净化的效果。那么这个流程在实际的车间生产中，又有哪些关键的技术？

Logically speaking, the air flow in the workshop → primary filtration and purification → air conditioning → medium efficiency filtration and purification → purifying air supply cabinet → air supply pipeline → efficient air supply outlet → blowing into the clean room → taking away particles such as dust and bacteria → return air shutters → primary filtration and purification, repeated this work process can achieve the purification effect. So what are the key technologies of this process in actual workshop production?

二、涂布无尘车间的关键技术和措施

1. 空气过滤

空气过滤是无尘车间的核心组成部分。通过高效空气过滤器（HEPA）或超高效空气过滤器（ULPA）对空气进行过滤，可以有效去除空气中的尘埃、细菌和其他微粒。在涂布车间，通常采用HEPA过滤器，以满足生产过程中对空气质量的要求。

2. 尘埃控制

尘埃控制是无尘车间的重要措施之一。主要包括以下几个方面：

（1）人员管理：进入无尘车间的人员需穿着专用洁净服，并经过吹淋、洗手等清洁处理。此外，还需定期对车间人员进行培训，提高他们对洁净室规范的认识。

（2）物料管理：物料进入无尘车间前需进行清洁处理，如脱脂、擦拭等。同时，在车间内设置物料缓冲区，减少物料在传递过程中的污染。

（3）设备管理：定期对生产设备进行清洁和维护，确保设备表面无尘埃、油污等污染物。同时，选用符合洁净室要求的设备，避免设备故障产生的尘埃。

2. Dust control Dust control is one of the important measures of a dust-free workshop. It mainly includes the following aspects: 

(1) Personnel management: The personnel who enter the dust-free workshop need to wear special clean clothes, and go through cleaning treatment such as blowing and washing hands. In addition, workshop personnel need to be regularly trained to improve their awareness of clean room specifications. 

(2) Material management: materials need to be cleaned before entering the dust-free workshop, such as degreasing, wiping, etc. At the same time, the material buffer zone is set up in the workshop to reduce the pollution of the material during the transfer process. 

(3) Equipment management: clean and maintain the production equipment regularly to ensure that there is no dust, oil and other pollutants on the surface of the equipment. At the same time, choose equipment that meets the requirements of the clean room to avoid dust caused by equipment failure.

3. 湿度和温度控制

湿度和温度是无尘车间环境控制的重要参数。在涂布过程中，适宜的湿度和温度有利于提高产品质量和减少尘埃生成。通常，无尘车间内的湿度控制在40%-60%，温度控制在18-22℃。通过空气调节系统，可以实现对湿度和温度的精确控制。

 3. Humidity and temperature control Humidity and temperature are important parameters for the environmental control of a dust-free workshop. In the coating process, suitable humidity and temperature are conducive to improving product quality and reducing dust generation. Usually, the humidity in the dust-free workshop is controlled at 40%-60%, and the temperature is controlled at 18-22 ° C. Through the air conditioning system, precise control of humidity and temperature can be achieved.

4. 洁净室设计

无尘车间的设计需考虑以下几个方面：

（1）布局：合理规划车间布局，将洁净区和非洁净区分开，避免交叉污染。同时，设置足够的风道面积，确保空气流通。

（2）气流组织：采用乱流或层流气流组织方式，使空气从洁净度高的区域流向洁净度低的区域，实现尘埃的有序流动。

（3）墙壁和地面：选择防尘、易清洁的材料，如不锈钢、瓷砖等。地面需设有坡度，便于冲洗和排放污染物。

4. Clean room design The design of the clean room workshop needs to consider the following aspects: 

(1) layout: reasonable planning of the layout of the workshop, separating the clean area and the unclean area to avoid cross contamination. At the same time, set up enough air duct area to ensure air circulation. 

(2) Airflow organization: Turbulence or laminar airflow organization is used to make the air flow from the area with high cleanliness to the area with low cleanliness to achieve the orderly flow of dust. 

(3) Walls and floors: choose materials that are dust-proof and easy to clean, such as stainless steel, tiles, etc. The ground should be sloped to facilitate flushing and discharge of pollutants.
