手板工艺中的塑料喷涂工艺流程，你知道吗？接下来由济南手板厂家为大家进行简单地介绍吧。手板工艺之塑料喷涂工艺流程包含5个方面：

Do you know the process flow of plastic spraying in the hand board process? Next, let's have a brief introduction from Jinan Handboard Factory. The plastic spraying process of the hand board process includes five aspects:

1.退火：退火是指塑件成型时产生的应力的过程。退火是为了避免涂装后应力集中处开裂问题。退火处理是把塑料成型件加热到热变形温度以下，保温2h即可应力。

1. Annealing: annealing refers to the process of relieving the stress generated during the forming of plastic parts. Annealing is to avoid cracking at the stress concentration after coating. Annealing treatment is to heat the plastic molding to the temperature below the thermal deformation temperature, and the stress can be relieved after holding for 2h.

2.除油：塑料件表面常沾有油污、手汗和脱模剂，它会使涂料附着力变差，涂层产生龟裂、起泡和脱落。涂装前应进行除油处理。对塑料件通常用汽油或酒精清洗，然后进行化学除油化学除油后应清洗工件表面残留碱液，并用纯水后清洗干净，晾干或烘干。

2. Degreasing: The surface of plastic parts is often stained with oil stain, hand sweat and release agent, which will make the adhesion of the coating poor, and the coating will crack, blister and fall off. Oil removal shall be carried out before painting. The plastic parts are usually cleaned with gasoline or alcohol, and then the residual lye on the surface of the workpiece shall be cleaned after chemical degreasing, and cleaned with pure water, dried or dried.

3.除电及除尘：塑料制品是绝缘体，表面电阻一般在1013Ω左右，易产生静电。带电后容易吸附空气中的细小灰尘而附着于表面。因静电吸附的灰尘用一般吹气法除去十分困难，采用高压离子化空气流同时除电除尘的效果较好。

3. Electricity removal and dust removal: plastic products are insulators, and the surface resistance is generally about 1013 Ω, which is easy to generate static electricity. After electrification, it is easy to absorb fine dust in the air and attach to the surface. Because it is very difficult to remove the dust adsorbed by static electricity by general air blowing method, it is better to use high-pressure ionized air flow to remove the electrostatic dust at the same time.

4.喷涂：塑料涂层厚度为15~20μm，通常要喷涂2~3道才能完成。一道喷涂后晾干15min，再进行第二次喷涂。需要光亮的表面还须喷涂透明涂料。涂后的制件对于阻燃性能基本没有影响。

4. Spraying: plastic coating thickness is 15~20 μ m. It usually takes 2-3 coats to finish. Dry for 15min after the first spraying, and then conduct the second spraying. The surface that needs to be bright must also be sprayed with transparent paint. The coated parts have no effect on the flame retardance.

5.烘干：涂完后可在室温下自干，也可在60℃条件下烘烤30min。正确的塑料喷涂工艺可以提高产品质量，也可以提高生产效率。苏州金瑄工贸有限公司多年从事塑料喷涂加工，拥有成熟的加工工艺。

5. Drying: after coating, it can be dried at room temperature or baked for 30min at 60 ℃. Correct plastic spraying process can improve product quality and production efficiency. Suzhou Jinxuan Industry and Trade Co., Ltd. has been engaged in plastic spraying processing for many years and has mature processing technology.
