Selection and Maintenance of Diesel Generator Set Painting

Jan. 10, 2019

At present, the generator shell paint products on the market are dazzling, and the functions of each series are different. How to choose a generator shell paint product that is suitable for yourself and the economy and whether there are tricks in the use of the generator shell paint to save unnecessary expenses is a concern of many users.

Misunderstanding 1. The generator shell paint zero VOC is the best

 

As with other paint products, the environmental friendliness of generator casing paint has become the focus of business and consumers. The VOC of the generator casing paint refers to the total amount of organic compounds contained in the paint, and these organic compounds are the main components of the main film-forming materials that constitute the paint of the generator casing. The role of the main film-forming material is to enhance the viscosity of the paint of the generator casing, which is what the saying goes as the paint of the generator casing. If the content of VOC is lowered, it is likely to cause a decrease in the viscosity of the paint of the generator casing, which may result in paint dusting, foaming, cracking, and low scrub resistance of the generator casing.

 

Experts said that if the quality of the paint on the outer casing of the generator is not taken into consideration, it is very simple to simply reduce the VOC content. For example, adding more water to the paint of the generator casing can reduce the VOC content. Therefore, some small generator shell paint manufacturers can make VOC very low, but the quality is not guaranteed. Experts stressed that the generator casing paint has a mandatory national standard as a product that directly enters the spray. The qualified products sold on the market have already reached this standard, and are environmentally friendly and harmless. Therefore, consumers do not have to keep an eye on the contents of “environmental protection” and “VOC” when purchasing the paint of the generator casing. As long as they are qualified products that meet the national standards, they can be assured to buy.

 

Misunderstanding 2. Generator shell paint pursues self-cleaning function and scrub resistance

 

At present, many generator shell painters use the product's self-cleaning function and thousands of times of scrubbing as a promotional point. Experts said that the self-cleaning statement is applied to the outer generator shell paint, which refers to the stain resistance of the generator shell paint, which is also known as the dirt resistance. Specifically, the paint of the generator casing is not easily stained with dust after being treated, and the dust that has been stained on the surface can be washed away by the flushing of the rainwater, thereby achieving a clean effect. Although some merchants inject self-cleaning functions into the paint of the generator casing, in fact, most of the paint cleaning of the generator casing is still done by manual scrubbing.

 

The national standard stipulates that the scrub resistance of the paint of the qualified generator casing is not less than 300 times, and the number of scrubs promoted by some generator shell paints has reached tens of thousands of times. This is a good thing, indicating that the scrubbing properties of these generator shell paints are good. , but the cost should be increased accordingly. As a consumer, the paint on the generator casing is rubbed once a day for 3,560 times. Therefore, consumers should not excessively pursue self-cleaning function and scrub resistance when purchasing generator shell paint.

 

Misunderstanding 3: It is the crack-proof generator shell paint that can cover the crack.

 

Many consumers think that the paint of the generator casing that can cover the crack is the paint of the crack-proof generator casing. In fact, the function of crack-proof and generator cover paint covering micro-cracks is two different things. It is not that the motor is cracked, and the paint on the generator casing will not crack. Experts tell us that there is indeed a thick paint shell paint on the market, but this kind of generator shell paint is mostly used in outdoor motors, which is basically difficult to use in indoor generator surface, and the cost is very high. There is no specific requirement in the national standard for the elasticity of the paint of the diesel generator casing. In some coastal areas, due to the sinking of the foundation every year, the generator surface is easily cracked, and the paint of the elastic generator casing is widely used. However, as an ordinary consumer, it is not necessary to use a high-cost elastic generator casing paint in the home decoration.

 

Finally, Starlight recommends that consumers purchase a generator shell paint, look at the test report of the generator shell paint, and make a comprehensive analysis of other aspects of the generator shell paint. For example, the alkali resistance of the paint of the generator casing: the alkali resistance of the paint of the generator casing. If the alkali resistance of the paint of the generator casing is not strong, it is easy to yellow after a period of time. After making a comprehensive analysis, choose the products you really need.
