Requirement Of Pigment For Mechanical Paint

Pigment orange 13 manufacturer said, mechanical paint, also known as mechanical coatings, is a coating applied to the surface of machinery and all kinds of mechanical parts, mainly coated on the surface of machine tools, equipment, automobiles, hardware, glass fiber reinforced plastic and other surfaces, to play a decorative and protective role. What are the requirements for pigments when coloring mechanical paint? The following are the relevant requirements:

The requirements for paint pigments:
● Pollution resistance
● Durability: including resistance to freezing and thawing, washing resistance, aging resistance, weathering resistance and so on.
● Alkalinity resistance: the decorative objects of the paint are mainly some alkaline materials, so alkalinity is an important characteristic of the paint.
● Minimum film-forming temperature: Each kind of paint has a minimum film-forming temperature, and the minimum film-forming temperature is different for different paints.

Film Thickness
Mechanical products generally require a thick film, if you want to achieve a certain thickness, we need to spray more than once, a film requirements in the 20μm below the low-pressure spraying, film in the 20-40μm with medium-pressure spraying, the requirements of more than 40μm with high-pressure spraying.

Mechanical Strength
Mechanical products coating film should also be able to anti-knock, anti-friction, that is, the mechanical strength should be high, which is very important. To achieve the desired strength, must take into account the film to be thick, high film hardness, good adhesion.
Which film hardness is also dependent on the quality of the paint itself and the ideal baking effect, the general baking paint is higher than the hardness of the self-drying paint, so the design of the general use of the baking process for processing.

Adhesion
Adhesion is a measure of mechanical strength is an important indicator, the treatment of good and bad is the core of the adhesion, engineering machinery products structural parts are generally used in the way of shot blasting treatment, treatment and then blowing dust, pretreatment phosphating, primer, its main purpose is to make the paint film to achieve the best state of adhesion.

Among them, Pigment Yellow 110 is mainly used in metal decorative paints, automobile paints and latex paints. Plastic coloring shows excellent thermal stability, light fastness is one of the most light-resistant varieties of known yellow organic pigments. Heat resistance in HDPE has reached 290°C. It is suitable for primary coloring of polypropylene, polyacrylonitrile and polyamide, and is also used in a variety of printing inks. It possesses good solvent resistance, heat resistance and resistance to sterilizing treatments, and can be applied to fine art pigments, solvent-borne wood coloring, and so on.
The choice of spraying method also has a great influence on the adhesion, the higher the rate of paint advance, the closer the relative adhesion, if there is static electricity, can also improve the adhesion.

Marble Resistance
Most of the working environment of engineering machinery products in the outdoors, it is required to have a very good good weather resistance, coating film to be able to resist corrosion, resistance to the harsh outdoor environment, so the weather resistance requirements of the pigment is essential, but also requires the coating film to be uniform, uniform adhesion, to avoid pinholes, bubbles and so on.

Gloss
Mechanical paint gloss is good or bad mainly depends on the fine degree of atomization, the finer the atomization, the better the gloss. Mechanical surface is beautiful gloss is the best embodiment of good, engineering machinery products do not require gloss like cars, but the surface of the same beautiful symbol of the quality of the product, up to the technical indicators at the same time the gloss will be improved, engineering machinery by making the sub-film thickness to achieve a more desirable luster, the use of atomized air-assisted airless spraying.
