　　涂装生产线工艺流程分为：前处理、喷粉涂装、加热固化。

　　The process flow of the painting production line is divided into pre-treatment, powder coating, and heating curing.

　　涂装生产线前处理工段的生产

　　Production of pre-treatment section of painting production line

　　前处理有手动简易工艺和自动前处理工艺，后者又分自动喷淋和自动浸喷两种工艺。工件在喷粉之前必须进行表面处理去油去锈。在这一工段所用药液较多，主要有除锈剂、除油剂、表调剂、磷化剂等等。

　　There are manual and automatic pre-treatment processes for pre-treatment, with the latter being divided into two types: automatic spraying and automatic immersion spraying. The workpiece must undergo surface treatment to remove oil and rust before powder coating. There are many chemicals used in this section, mainly including rust remover, oil remover, surface conditioner, phosphating agent, etc.

　　在涂装生产线前处理工段或车间，第一要注意的就是制定必要的强酸强碱购买、运输、保管和使用制度，给工人提供必要的保护着装，安全可靠的盛装、搬运、配置器具，以及制定万一发生事故时的紧急处理措施、抢救办法。其次，在涂装生产线前处理工段，由于存在一定量的废气、废液等三废物质，所以在环保措施方面，必须配置抽气排气、排液和三废处理装置。

　　In the pre-treatment section or workshop of the painting production line, the first thing to pay attention to is to establish necessary regulations for the purchase, transportation, storage, and use of strong acids and alkalis, provide workers with necessary protective clothing, safe and reliable packaging, handling, and equipment configuration, and develop emergency response measures and rescue methods in case of accidents. Secondly, in the pre-treatment section of the painting production line, due to the presence of a certain amount of waste gas, waste liquid, and other three waste substances, it is necessary to install exhaust, liquid discharge, and three waste treatment devices in terms of environmental protection measures.

　　前处理过的工件质量，由于前处理液及涂装生产线工艺流程不尽相同，其质量当有差异。处理较好的工件，表面油、锈去尽，为了防止短时间内再次生锈，一般应在前处理后几道工序，进行磷化或钝化处理：在喷粉前，还应将已磷化的工件进行干燥，去其表面水分。小批量单件生产，一般采用自然晾干、晒干、风干。而对于大批量之流水作业，一般采取低温烘干，采用烘箱或烘道。

　　The quality of pre treated workpieces may vary due to differences in the pre-treatment liquid and coating production line processes. For well processed workpieces, the surface oil and rust should be completely removed. In order to prevent rusting again in a short period of time, phosphating or passivation treatment should be carried out in several processes after pre-treatment. Before powder coating, the phosphated workpiece should also be dried to remove its surface moisture. Small batch single piece production generally adopts natural air drying, sun drying, and air drying. For large-scale assembly line operations, low-temperature drying is generally adopted, using ovens or drying channels.

　　喷粉涂装的组织生产

　　Organization and production of powder coating

　　对于小批量工件，一般采取手动喷粉装置，而对于大批量工件，一般采用手动或自动喷粉装置。无论是手动喷粉或自动喷粉，把住质量关是非常重要的。要确保被喷工件着粉均匀、厚度一致，防止薄喷、漏喷、擦落等缺陷。

　　For small batches of workpieces, manual powder spraying devices are generally used, while for large batches of workpieces, manual or automatic powder spraying devices are generally used. Whether it is manual or automatic powder spraying, it is very important to control the quality. To ensure even powder coating and consistent thickness of the sprayed workpiece, and prevent defects such as thin spraying, missed spraying, and wiping off.

　　?

　　What?

　　在涂装生产线引这一工序，还应注意工件之挂钩部分，在进入固化之前，应尽可能将附着其上的粉末吹掉，防止挂钩上之多余粉末固化，有的对固化前去掉余粉确有困难时，应及时剥离挂钩上已固化之粉膜，从而确保挂钩导电良好，以利下批工件易于着粉。

　　In the painting production line, attention should also be paid to the hook part of the workpiece. Before entering the curing process, the powder attached to it should be blown off as much as possible to prevent the excess powder on the hook from curing. If it is difficult to remove the excess powder before curing, the cured powder film on the hook should be peeled off in a timely manner to ensure good conductivity of the hook and facilitate the powder coating of the next batch of workpieces.

　　涂装生产线固化工序生产

　　Curing process production of coating production line

　　这一工序应注意的事项有：喷好的工件，如果是小批量单件生产，进固化炉前注意防止碰落粉末，如有擦粉现象，应及时补喷粉末。烘烤时严格工艺及温度、时间控制，切实注意防止色差、过烘或时间过短造成固化不足。

　　The precautions to be taken in this process include: for workpieces that have been sprayed, if they are produced in small batches, be careful to prevent powder from falling off before entering the curing furnace. If there is any powder scraping phenomenon, powder should be sprayed in a timely manner. Strictly control the process, temperature, and time during baking, and pay attention to preventing color difference, over baking, or insufficient curing caused by too short a time.

　　对于大批量自动输送的工件，在进烘道前同样要仔细检查是否漏喷、喷薄或局部擦粉现象，如发现不合格件，应把好关防止进入烘道，尽可能取下重喷。如个别工件因薄喷不合格，在固化出烘道后可以重喷再次固化。

　　For workpieces that are automatically transported in large quantities, it is also necessary to carefully check for any missed spraying, thinning, or localized powder wiping before entering the drying oven. If any non-conforming parts are found, they should be carefully inspected to prevent them from entering the drying oven and removed for re spraying as much as possible. If individual workpieces are not qualified due to thin spraying, they can be re sprayed and re cured after curing in the drying oven.

　　所谓涂装即指对金属和非金属表面覆盖保护层或装饰层。涂装流水线经历了由手工到生产线、到自动生产线的发展过程，自动化的程度越来越高，所以涂装生产线的应用也越来越广泛，并深入到国民经济的多个领域。

　　The so-called painting refers to covering metal and non-metal surfaces with protective or decorative layers. The painting production line has gone through a development process from manual to production line, and to automatic production line. The degree of automation is becoming higher and higher, so the application of painting production line is becoming more and more widespread, and it has penetrated into multiple fields of the national economy.

　　注意事项

　　Precautions

　　一、涂装生产线上应注意被涂物件的装挂。预先通过试浸来设计挂具及物件在涂装生产线上的装挂方式，保证工件在浸涂时处于最佳位置。被涂物的最大平面应接近垂直，其他平面与水平呈10°-40°角，使余漆的涂装面上能够较流畅地流尽。

　　1、 Attention should be paid to the installation and hanging of the coated objects on the painting production line. Pre design the hanging method of fixtures and objects on the coating production line through trial immersion to ensure that the workpiece is in the optimal position during immersion coating. The maximum plane of the coated object should be close to vertical, and other planes should form an angle of 10 ° -40 ° with the horizontal, so that the remaining paint can flow smoothly on the coated surface.

　　二、在涂装生产线上涂装时为防止溶剂在车间内的扩散和尘埃落入漆槽内，浸漆槽应保护起来。

　　2、 To prevent solvent diffusion and dust from falling into the paint tank during painting on the painting production line, the immersion tank should be protected.

　　三、大型物件在涂装生产线上浸涂后，应待溶剂基本挥发后再送入烘房。

　　3、 After immersion coating on the painting production line, large objects should wait for the solvent to evaporate before being sent to the drying room.

　　四、涂装时要不断注意涂料粘度的测定，每班应测定1-2次粘度，若粘度增高超过原粘度的10%，就应及时补加溶剂。添加溶剂时，应停止浸涂作业。搅拌均匀后，测定粘度，然后再继续作业。

　　4、 During painting, constant attention should be paid to the determination of paint viscosity. The viscosity should be measured 1-2 times per shift. If the viscosity increases by more than 10% of the original viscosity, the solvent should be added in a timely manner. When adding solvents, the immersion coating operation should be stopped. After stirring evenly, measure the viscosity before continuing the operation.

　　五、漆膜的厚度主要决定于涂装生产线上物体提升的速率以及漆液的粘度。在按上述要求控制了漆液的粘度后，涂装生产线应按照漆膜30um左右的最大限速度，根据不同的设备，实验确定合适的提升速率。按此速率均匀地提升被涂物件。提升速率快，漆膜薄；提升速率慢，漆膜厚且不均匀。

　　5、 The thickness of the paint film is mainly determined by the rate of object lifting on the coating production line and the viscosity of the paint solution. After controlling the viscosity of the paint according to the above requirements, the coating production line should determine the appropriate lifting rate through experiments based on different equipment, with a maximum speed limit of about 30um for the paint film. Lift the coated object evenly at this rate. Fast improvement rate and thin paint film; Slow improvement rate, thick and uneven paint film.

　　六、在涂装生产线上进行浸涂操作时，有时造成被涂上、下部的漆膜具有厚度差异，尤其是在被涂物的下边缘出现肥厚积存。为提高涂层的装饰性，在小批量浸涂时用刷子手工除掉多余积存的漆滴，也可用离心力或静电引力设备除掉这些漆滴。

　　6、 When performing dip coating operations on the painting production line, sometimes there is a difference in thickness between the paint film on the upper and lower parts of the coating, especially when there is thickening and accumulation at the lower edge of the coated object. To improve the decorative effect of the coating, excess accumulated paint droplets can be manually removed with a brush during small batch immersion coating, or these paint droplets can be removed using centrifugal force or electrostatic attraction equipment.

　　七、在涂装生产线上浸涂木制件时，注意时间不能太长，以免木材吸入过量的涂料，造成慢干和浪费。

　　7、 When dipping wooden parts on the coating production line, it is important to note that the time should not be too long to prevent the wood from absorbing excessive paint, resulting in slow drying and waste.

　　八、加强通风设备，防止溶剂蒸气的危害；注意防火措置的安排和定期检查涂装生产线。

　　8、 Strengthen ventilation equipment to prevent the harm of solvent vapor; Pay attention to the arrangement of fire prevention measures and regularly inspect the coating production line.
