一、水性涂料涂裝生產(chǎn)線的工藝設(shè)計(jì)的優(yōu)點(diǎn)：

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

1.操作人員有健康保證：水性涂料僅采用少量低毒性醇醚類有機(jī)溶劑，改善了涂裝生產(chǎn)線的作業(yè)環(huán)境，有利于工作人員的健康。

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：水性涂料涂裝工具可用水清洗，大大減少清洗溶劑的消耗。

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

3.環(huán)保要求達(dá)標(biāo)：以水作為稀釋劑及用水清洗噴涂涂裝設(shè)備器具，一般的水性涂料有機(jī)溶劑(占涂料)在10%～15%之間，而現(xiàn)在的陰極電泳涂料已降至1.2%以下，有機(jī)溶劑大幅度降低，節(jié)省資源效果顯著，減少了涂裝廢氣處理對(duì)大氣的污染，更能達(dá)到國家環(huán)保要求，從而保護(hù)環(huán)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.耐腐蝕：涂裝電泳線的涂料可以對(duì)復(fù)雜的工件進(jìn)行涂裝，內(nèi)腔、焊縫、棱角、棱邊部位都能涂上一定厚度的涂膜，提高了工件的耐腐蝕性。

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.附著力強(qiáng)：水性涂料在濕表面和潮濕環(huán)境中可以直接涂覆施工，水性涂料對(duì)材質(zhì)表面適應(yīng)性好，涂層附著力強(qiáng)。

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.減少火災(zāi)危害：水性涂料以水作溶劑，節(jié)省大量資源，水性涂料消除了施工時(shí)火災(zāi)危險(xiǎn)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、水性涂料涂裝生產(chǎn)線的工藝設(shè)計(jì)的缺點(diǎn)：

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

1.水性涂料電導(dǎo)率高，使用靜電噴涂時(shí)，需要絕緣等特殊處理措施。

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

2.因?yàn)樗木壒?，容易滋生?xì)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.表面張力打，對(duì)施工過程中的材質(zhì)基材表面清潔度要求高，污染易使涂膜產(chǎn)生縮孔。

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.水性涂料蒸發(fā)潛熱大，作為稀料的水揮發(fā)性不好，容易引起流掛、針孔、起泡等涂層缺陷；流平及固話時(shí)，能量消耗大，碳排放量增加，而且對(duì)涂裝生產(chǎn)線的環(huán)境、濕度要求高。

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.水性涂料腐蝕性強(qiáng)，對(duì)涂裝設(shè)備腐蝕性大，運(yùn)輸途中，輸送管路的腐蝕性強(qiáng)，需要采用不銹鋼管，做好防護(hù)措施，設(shè)備改造大。

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響變化很大，在收到高剪切力作用時(shí)，水性涂料的粘度會(huì)下降很多，會(huì)對(duì)輸調(diào)漆系統(tǒng)帶來很大的影響。

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.室溫低于5攝氏度以下時(shí)不宜存儲(chǔ)，容易凍壞。

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