How to paint paint deployment deployment
Paint is the material that people need to use for decoration. At present, the color of paint on the market is not too much, many colors are deployed. In general, paint deployment is a technical activity that requires professionals to complete it. However, amateurs can master the same skills through learning. So how do you paint? What are the precautions for the deployment of paint colors? The following Xiaobian will share these issues with you and look forward to helping you.
How to mix a paint
To modulate the desired color, you should choose the appropriate color. If the selected color is not suitable, the resulting paint will not achieve the desired effect. For example, in the deployment of green, any yellow and blue can be assigned to medium green, but only in the case of yellow and blue purity of the green light is more pure and bright.
How to mix paint two
The deployment of paint is a technical activity and is usually done by experienced oil workers. Based on past practical experience, experienced workers can identify which monochromatic color the excellent board color is after contrasting with the swatches, and the proportion of each monochrome is roughly the same, and then use the same kind of paint as the Matching. After being approved by the design and construction unit, the same or similar painting method as the template is used to paint the same color as the template.
What are the precautions for paint deployment?
Modulating paint is not a simple matter. Everyone needs to pay attention to more matters in the process of modulation. Everyone should first determine the number of color paints in the paint template or sample, and then estimate the weight of various paints participating in color matching as a basis for deploying large samples.
What are the two notes of paint preparation?
Everyone should not mix all kinds of paint together when preparing, and should follow a certain order. In the color match, we should first add the main color paint, and then use the color paint with strong coloring as the secondary color, slowly and intermittently add the main color paint, and constantly stir. Control the sample or sample, observe it at any time, read it out. Must be patiently deployed to adjust the color to meet the requirements.
What are the three considerations of paint preparation?
I believe that many people have had this experience. When they painted the paint, they felt that the color was just right, but when the paint dried, it was found that the color was too dark. This is because the color paint is light when it is wet, and the color will turn deep after it is dried. Therefore, in the color matching process, the color of the wet paint is slightly lighter than that of the paint on the sample plate. In order to make the depth of paint suitable for deployment, we should first understand the floating degree of a certain primary color in the complex paint and the change of the paint. Happening.
What are the four notes of paint preparation?
Everyone should not use pure color paints when deploying paints. This is because the paint colors have different colors. For example, in the case of a green match, yellow heads with green heads and blue heads with yellow heads are generally used; When using it, it is necessary to use blue with a trace of red and a red pigment with a trace of blue so that good results can be produced.
What are the five notes for paint preparation?
If you feel that the color is too dark, you can add some white paint to the paint. Everyone can add different amounts of white according to the actual needs to dilute the primary color or the complex color to get different shades of light, such as light blue, Light blue, sky blue, blue, dark blue and so on. By adding different amounts of black, different colors with different brightness can be obtained, such as gray, brown, brown, grass green, and the like.
Now many paints produced by paint manufacturers are basic colors. These colors cannot always meet the needs of the owners and therefore need to be re-modulated. It is worth noting that only paints of the same nature can be blended, and paints of different properties cannot be matched against each other, otherwise they will cause segregation, sedimentation, floating color, and even scrapping, resulting in waste. The above is the deployment of paint colors, and the colors to be deployed will be unique. You will also praise your talents.
Plate rolling is a process of continuous three-point bending of sheet metal using a plate rolling machine. The equipment puts the sheet material between the upper and lower work rolls when rolling. The upper roller is raised and lowered vertically, and the two lower rollers rotate and move horizontally relative to the axis of the upper roller. When the upper roll descends, the plate is plastically deformed and bent between the upper and lower work rolls. The continuous rotation of the bottom roller drives the steel plate to advance and retreat through the friction between the plate and the roller to complete the coiling.
1. Pre-bending. When the plate is rolled, there is a length at both ends of the plate that does not bend because it does not touch the upper roller. It is called the remaining straight edge. In the process, the minimum force arm at which the plate starts to bend is called the theoretical remaining straight edge. The bending form (symmetrical bending, asymmetrical bending) is related.
2. Centering. The purpose of centering is to make the generatrix of the workpiece parallel to the roller axis to prevent skew.
3. Roll round. Rolling is the main process of product forming, which is divided into two types: one-time feed and multiple feeds. Multiple feeds are commonly used for rolling thick plates. The number of feeds depends on the technological constraints (such as the maximum allowable deformation during cold rolling) and equipment constraints (such as non-slip conditions and power conditions). When the rebound of the cold coil is significant, a certain amount of overcoiling must be added.
4. Straightening round. The purpose of rounding is to make the curvature of the entire circle as uniform as possible to ensure product quality. The general rounding process is divided into three steps:
(1) Load: According to experience or calculation, adjust the work roll to the position of the required maximum correction curvature.
(2) Rounding: Roll the roller 1 to 2 turns under the corrected curvature to make the entire curling rate uniform.
(3) Unloading: gradually unload the load, so that the workpiece is rolled several times under the gradually reduced correction load.
