What are the hazards of spray painting in Dalian?

Dalian metal plastic spray paint contains a lot of harmful chemicals such as formaldehyde and benzene, which can easily induce leukemia. Its harm to the human body has the characteristics of long-term, latent, and hidden, so it is easily overlooked by people. The harm of spray painting is greater. Spray painting takes longer than paint mixing, and paint mixing is only a process of adjusting the physical parameters of the paint solution during the use of the coating according to the needs. Usually, a diluent (also known as a solvent or thinner) is used to adjust the viscosity of the paint solution.

Spray painting is a method of applying evenly and finely dispersed mist droplets onto the surface of the object being painted using a spray gun and air pressure. Spray painting without protection, the concentration of benzene in the workplace air is quite high, which poses a great threat to spray painting workers. Long term exposure to benzene can cause chronic poisoning, leading to diseases such as leukopenia, thrombocytopenia, and impaired bone marrow hematopoietic function.

Dalian metal plastic spray painting is a more traditional way of painting, using brushes for construction. Brushing also has brush marks, and the brush is prone to shedding hair; The construction efficiency is the lower of the three painting methods, which is time-consuming and laborious; And when encountering paint with fast drying or poor leveling, it is easy to have brush marks and uneven paint film. Leave it in a dry place for at least one week, and after the paint surface is completely dry, polish it thoroughly. When repainting, the principle should be to spray less and multiple times. For color paint, as long as the color is uniform, it is considered good. Spray layer by layer, don't be impatient, spray thick at once. Color paint does not require pursuing thickness.

After spraying the varnish, let it sit for one to two weeks until it is completely dry. You can choose to polish it with coarse to fine sandpaper to smooth the varnish surface. It would be even better if you could apply polishing paste. If not polished, the glossy surface is also very shiny, comparable to piano lacquer. When spraying paint, be sure to hold the spray can within a certain distance from the surface, and then use a uniform speed to spray paint, which can make the spray paint more even. In addition, you cannot spray paint at one point all the time, which can prevent paint from remaining. Before painting, it is necessary to try spraying to see the color effect, so that the painting can achieve the expected effect.
