涂裝流水線的工藝流程主要包括以下步驟：

　　The process flow of the painting assembly line mainly includes the following steps:

　　一、前處理

　　1、 Pre processing

　　投入產(chǎn)品：將被涂物放到插件上，準(zhǔn)備進(jìn)行涂裝作業(yè)。

　　Product input: Place the coated material on the plugin and prepare for coating operation.

　　靜電除塵：使用靜電除塵器在工作表面形成高壓負(fù)離子電場(chǎng)，并用高壓空氣流吹工件表面，以有效清除注塑時(shí)帶來(lái)的油質(zhì)、灰塵以及塑料表面電荷積累的帶電粒子所吸附的塵埃。

　　Electrostatic precipitator: Use an electrostatic precipitator to form a high-voltage negative ion electric field on the working surface, and blow the surface of the workpiece with a high-pressure air flow to effectively remove the oil, dust, and dust adsorbed by charged particles accumulated on the plastic surface during injection molding.

　　預(yù)處理：工件在噴粉之前必須進(jìn)行表面處理去油去銹。根據(jù)工件油污、銹蝕程度以及底漆要求，采用不同的工藝流程。一般油污、銹蝕、氧化皮混合工件常用的工藝流程是脫脂除銹“二合一”、水清洗、中和、表調(diào)、磷化、水清洗、烘干（或直接電泳）。在這一工段所用藥液較多，主要有除銹劑、除油劑、表調(diào)劑、磷化劑等。

　　Pre treatment: The workpiece must undergo surface treatment to remove oil and rust before powder coating. Different process flows are adopted based on the degree of oil contamination, corrosion, and primer requirements of the workpiece. The commonly used process for mixed workpieces with oil stains, rust, and oxide scales is the "two in one" degreasing and rust removal, water cleaning, neutralization, surface adjustment, phosphating, water cleaning, drying (or direct electrophoresis). There are many chemicals used in this section, mainly including rust remover, oil remover, surface conditioner, phosphating agent, etc.

　　二、涂裝

　　2、 Painting

　　預(yù)熱：為了更好地上色，給被涂物加熱。

　　Preheating: To achieve better coloring, heat the object being coated.

　　底漆噴涂：把塑料本身的顏色覆蓋，為生產(chǎn)要求的顏色先底色噴涂。

　　Primer spraying: Covering the color of the plastic itself, and spraying the base color first to meet the production requirements.

　　烘干：通過(guò)隧道里的IR區(qū)進(jìn)行烘干，使底漆達(dá)到半干狀態(tài)，為下一道噴涂作準(zhǔn)備。

　　Drying: Drying is carried out through the IR zone in the tunnel to achieve a semi dry state of the primer, preparing for the next spray coating.

　　表面噴涂：按照生產(chǎn)要求噴涂上色。

　　Surface spraying: Spray and color according to production requirements.

　　三、固化與后處理

　　3、 Curing and post-processing

　　溜平干燥：通過(guò)隧道進(jìn)行溜平與烘干。

　　Smooth drying: Smooth and dry through tunnels.

　　UV噴涂固化：使用UV涂料，并搭配UV365nm光線，按照涂料要求的照色量（如800~1200mj）進(jìn)行瞬間固化。

　　UV spray curing: Use UV coating and combine it with UV365nm light to achieve instant curing according to the required color exposure of the coating (such as 800~1200mj).

　　冷卻：經(jīng)過(guò)高溫固化的工件需要進(jìn)行冷卻處理。

　　Cooling: Workpieces that have undergone high-temperature solidification require cooling treatment.

　　檢查與包裝：對(duì)涂裝完成的工件進(jìn)行檢查，確保質(zhì)量合格后進(jìn)行包裝。

　　Inspection and packaging: Inspect the painted workpieces to ensure quality before packaging.

　　四、注意事項(xiàng)

　　4、 Precautions

　　在涂裝生產(chǎn)線上涂裝時(shí)，為防止溶劑在車(chē)間內(nèi)的擴(kuò)散和塵埃落入漆槽內(nèi)，浸漆槽應(yīng)保護(hù)起來(lái)。

　　When painting on the painting production line, in order to prevent the diffusion of solvents in the workshop and dust from falling into the paint tank, the immersion tank should be protected.

　　大型物件在涂裝生產(chǎn)線上浸涂后，應(yīng)待溶劑基本揮發(fā)后再送入烘房。

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

　　涂裝時(shí)要不斷注意涂料粘度的測(cè)定，每班應(yīng)測(cè)定1~2次粘度，若粘度增高超過(guò)原粘度的10%，就應(yīng)及時(shí)補(bǔ)加溶劑。添加溶劑時(shí)，應(yīng)停止浸涂作業(yè)。

　　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.

　　在涂裝生產(chǎn)線上進(jìn)行浸涂操作時(shí)，可能造成被涂上、下部的漆膜具有厚度差異，尤其是在被涂物的下邊緣出現(xiàn)肥厚積存。為提高涂層的裝飾性，在小批量浸涂時(shí)可用刷子手工除掉多余積存的漆滴，也可用離心力或靜電引力設(shè)備除掉這些漆滴。

　　When performing dip coating operations on the painting production line, it may cause thickness differences between the paint film on the upper and lower parts of the coating, especially the accumulation of thickening 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 removed with centrifugal force or electrostatic attraction equipment.

　　在涂裝生產(chǎn)線上浸涂木制件時(shí)，注意時(shí)間不能太長(zhǎng)，以免木材吸入過(guò)量的涂料，造成慢干和浪費(fèi)。

　　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.

　　涂裝流水線經(jīng)歷了由手工到生產(chǎn)線、到自動(dòng)生產(chǎn)線的發(fā)展過(guò)程，自動(dòng)化的程度越來(lái)越高，在工業(yè)生產(chǎn)中發(fā)揮著重要作用。

　　The painting assembly line has gone through a development process from manual to production line, and to automatic production line. The degree of automation is becoming increasingly high and plays an important role in industrial production.
