Resolving minor paint problems Paint is an important part of interior decorating, and it is prone to some thorny problems that make people helpless. In fact, as long as you find out the real cause of the problem, it is not difficult to have satisfactory results for the remedy. The following is a solution to the problems that are easily caused by paint, so that you can be more comfortable in the interior decoration.
1. The peeling of paint may be due to the fact that the surface is too smooth. If the original paint is lacquer or powder (with untreated sizing paint), the new paint will not stick to the surface. Or it may be wood decay or metal rust, or peeling off due to poor paint quality.
A small area of ​​paint is peeling off. It can be sanded with fine sandpaper, then putty put on it, brushed with a primer and repainted. Exfoliation over a large area must scrape all the paint off and repaint it.
2. Foaming of paint Firstly, the foam is punctured. If water appears, it means that under the lacquer layer there is moisture infiltration underneath or behind it. After the sun is exposed to sunlight, the moisture evaporates into vapor, and the paint is lifted up into foam. At this point, the blistering paint is removed with a hot air gun, the wood is allowed to dry naturally, then the primer is applied, and finally the entire repair surface is repainted.
If there is no water in the bubble, it may be cracked wood grain, there is a small amount of air, the sun through the sun, the air expands, the paint bulge. Faced with this situation, first scrape off the blistering paint, then use a resin filler to fill the cracks, repaint it, or use no filler. After the paint is peeled off, apply a microporous paint directly.
3. In the case of cracks, the paint should be removed with a chemical paint remover or hot air gun and then repainted.
If the fracture range is not large, then sanding blocks or wet or dry sandpaper can be used to dilute the broken paint. After the surface has been smoothed, apply putty, apply a primer, and repaint it.
4. The paint flowing through the paint is too thick at one time, which will cause runny. The paint can not be dry yet. Brush it with a brush. If the paint has started to dry, dry it. Use a fine sandpaper to smooth the paint, clean the surface, clean it with a damp cloth, and re-apply it. Outer paint, be careful not to brush too thick.
5. There are many causes of stain on the surface of the stain. For example, the moisture in the latex paint dissolves the substance on the wall and the paint surface is rusted. The wall surface that is rubbed with the steel wool will cause rust spots, and the dark pipe inside the wall will appear with stains. In order to prevent stains, a layer of primer containing aluminum powder may be applied first. If stains are present, remove the emulsion paint at the stains first, brush the primer layer containing aluminum powder, and then re-paint.
6. Mouldy discoloration This problem occurs most often on wet paint surfaces, such as vapors that condense on glass or metal surfaces and often produce brown-black stains. At this point can be used fungicides, according to the instructions of the instructions to deal with moldy parts, to be killed after the mold, the surface clean and then re-paint.
7. The cause of loss of luster is that there is no primer, or that the primer and the inner layer of paint have not been dry and there is a light paint on it. As a result, the light paint is absorbed by the wood and loses its luster. The poor quality of glossy paint is also a reason.
Grind the old paint with wet or dry sandpaper, brush the dust, wipe the surface with a clean, damp cloth, and dry the paint again.
It is important to pay attention to the fact that paint is applied in very low temperatures and the paint film may lose its luster after it has dried.
8. The wrinkling of the film is usually caused by the second pass of the first pass of the paint. At this time, the solvent in the lower layer paint will affect the upper layer of the film to make it wrinkle.
In this case, the wrinkled paint film can be removed by chemical amalgamation or heating and repainted. Remember, we must wait until the first time after the paint is dry before we can go on the second pass.
9. Coarse paint The newly painted surface is rough, usually the paint brush used is not clean or contaminated by the surrounding environment. It is also possible that the paint is mixed with patent leather, which has not been precipitated and filtered before use, or has been dusted when the paint is dry.
In order to prevent these problems from occurring, clean paint brushes and paint buckets must be used. Before using the old paint, be sure to filter it with paint filter paper or clean nylon stockings. In addition, the painted surface should be covered with a cover or cardboard when the paint is dry to prevent dusting.
If the paint is rough, after it has dried, use a wet or dry sandpaper to polish it and clean it, then repaint it. Pay special attention to the paint brush must be clean.
The appearance of dark spots on the surface of the painted wood may be caused by the fact that the wood section was not sealed before being painted, and the sun was exposed to the sun, the wood section was heated, and the resin leaked from the wood section. At this point scraper can be used to scrape off the paint, and then polished with fine sandpaper to expose the knots, seal the knot with a knotted paint, and wait until dry, and then re-paint.
10. The paint does not dry well in the room or the temperature is too low, the paint will dry slowly. It is possible to open all doors and windows to promote ventilation, or put a heater indoors to increase room temperature.
If it still fails to solve the problem, it may be that the painted surface is greasy. This can be removed with a chemical paint remover or a heating method, thoroughly rubbing the surface, and then repainting.
11. Stick the lacquer on the lacquer surface as much as possible. When the paint is not dry, remove the larvae. Then use a brush to dip lightly on the surface. If the paint has started to dry out, wait for the paint film to harden completely, and then wipe off the bug. This will not mess the surface.

Short Radius Elbow refers to that the radius of curvature is 1 times of the elbow pipe diameter,also referred to as 1D.
Elbow push hot forming process is the use of special elbow pushing machine, mandrel and the heating device, so that pushing pipe raw material to forward movement in the mold set, be heated in motion, expanding and bending forming process. Elbow push hot deformation characteristics of tube diameter is determined according to the law of constant volume before and after deformation of the metal material, use smaller diameter than the diameter of the elbow, through mandrel to control the deformation process of the blank, to other parts of the compensation due to thinning of the diameter expands, thereby obtaining a uniform wall thickness of the elbow.
