Stages of colored plastic parts
The process of coating and spraying plastic surfaces varies due to the physical and chemical benefits of plastic or polymer materials compared to the color of metals and other materials. In general, the coating and coloration process of the plastic parts includes 2 steps:
Preparation and cleaning of the surface of the piece
For the painting of plastic surfaces, it is necessary to first prepare the new colors of the surface of the piece with the aim of increasing color and adhesion, better quality and durability. In fact, at this stage the surface of the components is cleaned and eliminates particles, impurities, plastic additions in plastic and fat surfaces, dust and contamination. If this step is not properly implemented, it may have a negative effect on its adhesion and colorability. At this point, cleaning and preparation of the surface of the piece can be manually done via solvent vapor, alkaline, acidic, emulsion, or by water -based solvent.
Activate the colorability and adhesion of the piece
generally vary the colorability of polymer and plastic materials compared to metals. Most plastic materials can be seen. The plastic material has a lower polarity and therefore has a negative effect on their adhesion. There are several ways to activate the colorability of the parts. This may be done through flame, electrical or chrona and plasma gas methods.
Run the coating (Astraksh and Plastic Painting)
The third step contains the scratching and coloration of the piece. Plastic pieces can be needed for the color of the type of gender. The paint of plastic parts can be done in many ways depending on the type of piece, the quality and type of color used for it. Usually the Astrakish and Color Painting Parts Parts include:
Primer Color
Basic Color and More
Original Color
Fixers such as
Drying and baking furnace (depending on the type and type of color)
is usually done in the furnace or anch in the drying process. One of the important parameters in baking furnaces is to sprinkle plastic parts, furnace temperature and cooking time. For baking plastic parts, a temperature of 2 ° C is used. Usually 5 minutes is needed to bake plastic parts.
Plasic coloring is challenging and requires unique tricks. Painting plastic surfaces requires special expertise not to lose quality when painting.
Staining on metal and iron surfaces
Metal surfaces have different types. The most widely used metals in construction, including iron and iron alloys such as steel. The main feature of iron is rust, which should be given special attention when staining. Aluminum is also a metal that is widely used and has no problem with rust. One of the methods used to prevent rust is to galvanize metal surfaces. At present, the most important metals in the construction and industry sector are iron. This metal has no significant mechanical and chemical resistance. The most important reasons for using it in the building sector is its low price. Irons act weak against various factors such as water, moisture and other cases. Rusting is the least side effects that the iron used in the building. The high complications of iron have led to more accuracy and obsession in how to color.
A variety of colors for metals
Since most of our accessories are made of metal, their color time disappears; So it is best to paint to maintain beauty. There are many special colors such as epoxy, oil alkidy, polyurethane and so on. The best color is for staining epoxy and polyurethane iron. The most widely used and main color for metals is epoxy. Epoxy -based resin is used to stain metal surfaces in the middle and last layers. Epoxy color is highly resistant to factors such as mechanical and chemicals, acids, bases and solvents. It can also withstand heat up to 2 degrees Celsius. Since epoxy color has a high chemical and variety structure; Therefore, it is widely used, especially in industries and can replace a large number of colors. Using this color is the best option for conditions and environment that is very high.
