The production model is often used in the airbrush introduction: it is evenly colored with the airbrush, and it can make camouflage and old effects. The cost of the airbrush is relatively expensive (mainly the gas pump is expensive, it takes four or five hundred pieces), but it can be used for a long time.
Huahui activated carbon can be divided into pellet
carbon, granular carbon, impregnated carbon , acid washed carbon, powder carbon
and briquette carbon etc, more than 6 kinds and hundreds of specifications.
Huahui can produce special activated carbon
to absorb mercury, high adsorption activity carbon with CTC larger than 120%
and particle diameter of activated carbon less than 0.9mm in the world advanced
level.
Acid washed carbon is Huahui Company's
fourth series of products. Through acid washing, alkali washing and special
technologies, Huahui can produce < 3% ultra low ash activated carbon.
The airbrush is a tool that uses compressed air to spray the model paint. It is believed that friends who have contacted art will not be familiar with it. Use the airbrush to paint more evenly, and you can make camouflage and old-fashioned effects. The cost of the airbrush is relatively expensive (mainly the gas pump is expensive, it takes four or five hundred pieces), but it can be used for a long time. If you want to make the perfect model and hand, it is recommended that you have as much as possible.
There are many varieties of airbrushes. GUNZE and Tamiya products are commonly found in the market. GUNZE's airbrush is relatively simple to use, the nozzle has a fixed diameter and the nozzle can be replaced.
The area of ​​the paint is controlled by adjusting the knob of the nozzle, and the trigger on the airbrush controls the amount of air. The nozzle has a diameter of 0.2 and 0.5.
Tamiya's airbrush is double-acting. Pressing the trigger controls the amount of air, and the force that pulls back controls the area of ​​paint spray. When using, both should be controlled at the same time, which requires constant practice to control freely.
Before you paint, you must first adjust the paint, the most important thing is to dilute the paint. In order to control the paint concentration, a pipette is generally used to control the amount of the solvent. How much solvent to use for dilution depends on the situation. Generally, the ratio of oil paint in Tamiya is slightly less than that of paint, which is close to 1:1. Water-based paints can be added with a small amount of solvent. If the paint is too thick, you can increase the air pressure to match. If the paint is too thin, you can lower the air pressure and extend the distance from the model surface.
Test spray before coloring with a spray pen. This allows testing the concentration and area of ​​the paint as well as the effect of the spray. If there is a problem, it is necessary to improve immediately. Don't take the model to try, you can try it with cardboard or newspaper. Through the test spray, adjust the angle of the nozzle, the size of the air pressure and the distance of the paint.
After the test spray is no problem, it can be officially colored. The method of coloring is the same as hand-painting, which is a cross-coating method. According to the cross-spray "spray" method, the model can be sprayed very evenly without accumulating too thick.
Generally speaking, the model is first combined, then polished, and then painted. However, some parts must be colored first, so it is necessary to use the color separation paper. The use of color separation paper is very important for coloring with a spray pen. Use a color separation paper to control the area of ​​the sprayed area. Especially when doing the hand, we often use the color separation paper to stick the curvature of the model to cover the colored areas. This step is sometimes more time-consuming than coloring, so be patient.
