This is the unique characteristic of YORTAY pearl pigment?

1. YORTAY pearlescent pigments are used in the leather industry. The pearlescent pigments have obvious effects, are non-toxic, odorless, high temperature resistant, and chemically inert. They are widely used in natural varnishes for the printing and surface coating of artificial leather, which can make the original monotonous The colors become richer. There are also pearlescent pigments that are blended into transparent resins to directly produce pearlescent leather, depending on the situation.

2. YORTAY pearlescent pigments are used in automotive coatings. The pearlescent pigments have stable physical properties and good dispersion. Almost all coatings can be applied. Just like general paint production, as long as ten days leave the right amount of pigment on the transparent substrate of various paints, pearl paint can be obtained, which is most suitable for coatings for automobiles, motorcycles, bicycles and other products. Pearlescent pigments have good acid and alkali resistance and are suitable for water-based graphics. They are resistant to sulfides. They will not have color changes when encountering sulfides. The pigments are non-conductive and are most suitable for electrostatic coating processing.

3. The application of YORTAY pearlescent pigments in the ink and paper printing industries. The pigments are rich in decorative effects. They can be used alone or mixed with other pigments and added to various inks, and then processed by silk screen, gravure, or flexible printing. The printing method is made into pearl ink, which can add elegant candlelight luster and metallic effect to paper, cardboard, wallpaper, plastic and textiles. Pearlescent pigments have various particle sizes, which can be selected appropriately according to the printing method.

(1) Reasonable use of pearlescent powder on composite paper. For example, printing pearlescent ink on PET composite paper. Due to the smoothness of the paper surface, the transfer rate of pearlescent ink decreases during the printing process, and the covering effect is also poor. The flower reveals the color of the paper. Then, in the process arrangement, consider that there is a spare color sequence, and print the pearlescent ink or primer twice, so that the pearlescent light effect will be more vivid; if there is no spare color sequence, consider adding appropriate aluminum powder, white ink or transparent to the pearlescent ink In this way, the pearlescent light effect is slightly lost, but the coverage rate is improved.

(2) The particle size of pearlescent pigments is relatively large, and screen printing has a very wide range of adaptability to ink particle size, so it is very suitable to use screen printing to reproduce the pearlescent effect. At the same time, screen printing can also produce many other special effects, which are favored by packaging users. But in terms of ink drying speed, the work efficiency of Zhuguanggang Printing is relatively low, and it is not suitable for mass printing. If uv ink is used instead of ordinary ink, although the curing speed can be increased, the high reflectivity of the printing surface has a great negative effect on the expression of some pearlescent pigments, so care should be taken when choosing pearlescent pigments. The printing plate used in flexographic printing is made of rubber or photosensitive resin, and the ink is transferred through the embossing on the printing plate. Flexographic printing inks are low-viscosity liquids, solvent-based and water-based, and dry quickly, especially under radiation curing. Due to its physical and chemical properties, Yao Dexing Technology's pearlescent pigments can be used in most inks used in flexographic printing. Traditional pigments have the characteristics of astigmatism, so when mixed with pearlescent pigments, they must be highly dispersed and cannot exceed 3% of the weight of the ink. In water-based alkaline inks, alkaline additives should be used to adjust the surface properties of pearlescent pigments. If an alkaline thixotropic agent is used to adjust the viscosity, the pigment with an acidic surface must be adjusted to avoid pigment flocculation and abnormal viscosity changes. To improve the dispersion of the pearlescent pigment in the ink, the pigment can be pre-wetted and dispersed before adding it to the ink. It is best to choose a substrate with a smooth, flat surface.

4. YORTAY pearlescent pigments are used in the offset printing industry. They have the advantages of convenient plate making and low cost. Many packaging printing plants like to use offset printing when trying new packaging products, especially pearlescent products. However, there are relatively few users who really use offset printing for pearlescent printing. The reason is that the ink layer of offset printing is thin and the ink path is long, which is not suitable for the transfer of relatively large and fragile pearlescent pigments, and there are certain difficulties in the dispersion of pigments. These problems often plague packaging and printing manufacturers, making pearlescent offset printing fail to achieve mass production. Therefore, further reducing the particle size of pearlescent pigments and enhancing the abrasion resistance of pearlescent pigments are the supplier's product development direction. In offset printing, ink is transferred through a flat printing plate. The printing plate has a flat printing area and a non-printing area. Use the incompatibility of oil and water to color the printing area of the printing plate. At present, offset printing uses thin aluminum plates that have been exposed to ultraviolet light. In most cases, fountain solution is still used to separate the printing and non-printing areas. Ordinary offset printing inks are high-viscosity inks and are not suitable for pearlescent pigments. Special printing inks should be used, and the ink manufacturer needs to adjust the ink composition according to the printing procedure. Commonly used packages and labels can be printed with pearlescent pigment offset inks. The surface of the substrate is as smooth and flat as possible to optimize the arrangement of the pigments and obtain the ideal gloss effect, because the ink layer in offset printing is very thin.

5. YORTAY pearlescent pigments are used in screen printing. In the screen printing, the printing ink is transferred from the screen plate to the substrate. The frame of the platform screen printing plate is stretched with a screen, and the screen is used to transmit image information, and the ink is squeezed out through the screen and printed on the substrate by a rubber roller or a scraper. The material selection and manufacturing technology of the screen have an important influence on the printing effect. The fiber of the screen is coarse.
