一、水性涂料涂装生产线的工艺设计的优点：

1、 The advantages of process design for water-based coating production lines:

1.操作人员有健康保证：水性涂料仅采用少量低毒性醇醚类有机溶剂，改善了涂装生产线的作业环境，有利于工作人员的健康。

1. Health assurance for operators: Water based coatings only use a small amount of low toxicity alcohol ether organic solvents, which improves the working environment of the coating production line and is beneficial to the health of workers.

2.易清洗：水性涂料涂装工具可用水清洗，大大减少清洗溶剂的消耗。

2. Easy to clean: Water based coating tools can be cleaned with water, greatly reducing the consumption of cleaning solvents.

3.环保要求达标：以水作为稀释剂及用水清洗喷涂涂装设备器具，一般的水性涂料有机溶剂(占涂料)在10%～15%之间，而现在的阴极电泳涂料已降至1.2%以下，有机溶剂大幅度降低，节省资源效果显著，减少了涂装废气处理对大气的污染，更能达到国家环保要求，从而保护环境。

3. Environmental protection requirements meet standards: Water is used as a diluent and water is used to clean spraying and painting equipment and equipment. Generally, the organic solvent (accounting for 10% to 15% of the coating) in water-based coatings is between 10% and 15%, while the current cathodic electrophoretic coatings have decreased to below 1.2%. The organic solvent has been greatly reduced, resulting in significant resource savings and reduced air pollution caused by coating waste gas treatment. This can better meet national environmental protection requirements and protect the environment.

4.耐腐蚀：涂装电泳线的涂料可以对复杂的工件进行涂装，内腔、焊缝、棱角、棱边部位都能涂上一定厚度的涂膜，提高了工件的耐腐蚀性。

4. Corrosion resistance: The coating of electrophoretic lines can be applied to complex workpieces, and a certain thickness of coating film can be applied to the inner cavity, welds, edges, and edges, improving the corrosion resistance of workpieces.

5.附着力强：水性涂料在湿表面和潮湿环境中可以直接涂覆施工，水性涂料对材质表面适应性好，涂层附着力强。

5. Strong adhesion: Waterborne coatings can be directly applied on wet surfaces and humid environments. Waterborne coatings have good adaptability to material surfaces and strong coating adhesion.

6.减少火灾危害：水性涂料以水作溶剂，节省大量资源，水性涂料消除了施工时火灾危险性。

6. Reduce fire hazards: Water based coatings use water as a solvent, saving a lot of resources. Water based coatings eliminate the fire hazards during construction.

二、水性涂料涂装生产线的工艺设计的缺点：

2、 Disadvantages of process design for water-based coating production lines:

1.水性涂料电导率高，使用静电喷涂时，需要绝缘等特殊处理措施。

1. Waterborne coatings have high conductivity, and special treatment measures such as insulation are required when using electrostatic spraying.

2.因为水的缘故，容易滋生细菌，因此要注意防腐防霉。

2. Due to water, it is easy to breed bacteria, so it is important to pay attention to anti-corrosion and mold prevention.

3.表面张力打，对施工过程中的材质基材表面清洁度要求高，污染易使涂膜产生缩孔。

3. Surface tension testing requires high surface cleanliness of the material substrate during the construction process, and contamination can easily cause shrinkage of the coating film.

4.水性涂料蒸发潜热大，作为稀料的水挥发性不好，容易引起流挂、针孔、起泡等涂层缺陷；流平及固话时，能量消耗大，碳排放量增加，而且对涂装生产线的环境、湿度要求高。

4. Water based coatings have a high latent heat of evaporation, and the water used as a diluent has poor volatility, which can easily cause coating defects such as sagging, pinholes, and foaming; When leveling and using fixed lines, energy consumption is high, carbon emissions increase, and high requirements are placed on the environment and humidity of the painting production line.

5.水性涂料腐蚀性强，对涂装设备腐蚀性大，运输途中，输送管路的腐蚀性强，需要采用不锈钢管，做好防护措施，设备改造大。

5. Waterborne coatings have strong corrosiveness and are highly corrosive to painting equipment. During transportation, the corrosion of the conveying pipeline is strong, and stainless steel pipes need to be used. Protective measures should be taken, and equipment renovation should be carried out.

6.水的粘度受剪切力影响变化很大，在收到高剪切力作用时，水性涂料的粘度会下降很多，会对输调漆系统带来很大的影响。

6. The viscosity of water is greatly affected by shear force, and when subjected to high shear force, the viscosity of water-based coatings will decrease significantly, which will have a significant impact on the paint transportation and blending system.

7.室温低于5摄氏度以下时不宜存储，容易冻坏。

7. When the room temperature is below 5 degrees Celsius, it should not be stored as it is prone to freezing damage.
