Dalian metal plastic painting, using roller construction, is a rough surface effect, which is similar to wallpaper. The so-called roughing, rough surface, knurling, texture and texture all refer to this kind of effect. Short hair roller is recommended for home decoration, which is easy to operate during construction, and the pattern is relatively shallow, which is easy to take care of daily; The large texture effect produced by the long hair roller is easy to hang ash, and it is also beautiful to make small areas such as TV background wall and corridor background.
Brush construction is a plane effect, but the brush will leave brush marks. Home decoration generally uses a wool brush. The wool brush is relatively soft and can minimize brush marks. When painting, the proportion of water added shall be controlled between 20-30%, not more than 35%. If the dilution ratio is higher than this, problems such as powder removal, sagging, floating color and bottom leakage are likely to occur. The dilution ratio with air injection is similar to that with brush. The dilution ratio without air injection varies with different machines, which is generally less than 20%.
Dalian metal plastic painting has a large waste of painting. After our statistics on a large number of construction, the answer is No. spraying is not more expensive than painting and rolling, especially the one-time film-forming thickness without air spraying can meet the construction requirements. The sprayed paint film is delicate, like a child's face; However, the film is thin, the protection ability of the wall is poor, it is not easy to repair, and the paint consumption is large. For flat paint, the effect of spraying and roller coating is not different, and the delicate feeling of spraying is not strong, which can not reflect the advantages of spraying. Roll coating is recommended to highlight the unique texture of flat paint For eggshell light and satin light paint, if you pursue the delicate feeling of paint film, you can choose to spray.
Scraping is a bit like puttying. It is mainly used for paints with high solid content, high viscosity and high gloss. It has high technical requirements for workers, otherwise there will be obvious scratches In addition, due to the thin film thickness of spraying. Baking paint is to apply three coats of primer and four coats of finish paint on the substrate. Each coat of paint is sent to the dust-free constant temperature baking room for baking. The edges and corners of the baked paint are smooth and the color is the same. It proves that the paint film is uniform and the color is full. The surface of the painted door panel is smooth without lines and orange peel.
The surface of Dalian metal plastic painted door panel is flat and smooth. Hit the baking paint with a hard object, there is no abnormality, and the paint film is not damaged. The advantages are bright color, strong visual impact, good surface finish, easy scrubbing, good moisture-proof and fire-proof performance. The paint baking door mostly uses the density board as the base material, and the back is trimeric hydrogen amine. The process is complex, the processing cycle is long, and the price is relatively high. The types of high-grade PU paint baking doors are divided into piano paint baking and metal (automobile) paint baking. Metal paint baking is better than piano paint baking.
