Zhongshan high-quality hardware baking paint wholesale factory, so the coating has good leveling property and good decoration, and the low molecular weight prepolymer can form cross-linked macromolecules after curing, so the coating has good corrosion resistance and mechanical properties. Therefore, thermosetting powder coatings are developing particularly rapidly

the selection of raw materials has laid a solid foundation for the safe use of special pigments. Advanced production processes and technologies provide customers with rich and colorful products. At the same time, strict quality testing provides a guarantee for the safety of products

main reasons

1. The viscosity of UV oil is too small and the coating is too thin

2, ethanol and other non reactive solvents are diluted excessively

3, uneven coating

4. The paper is too absorbent

5. The glue roll is too fine and the oil supply is insufficient

the solution of Zhongshan high-quality hardware baking paint wholesale manufacturer: appropriately increase the viscosity and coating amount of UV varnish according to the different conditions of the paper: a layer of primer can be applied to the paper with strong absorption

second, the contribution of these components to the performance of the formed powder coating is mutual restriction and influence. A suitable formula is actually the result of the coordination of various components. The special pearlescent pigments produced at present are all made of materials that can be used in the parts of the human body in the CI catalogue, such as the diameter limitation of the collet that can hold the sample, most of which are inorganic materials, and a small amount of natural pigments are used. The main reasons are

1, insufficient UV intensity

2. The ultraviolet lamp tube is aging and the light intensity is weakened

3. The storage time of UV varnish is too long

4. Too many diluents that do not participate in the reaction are added

5. The machine speed is too fast

the resin used in thermosetting powder coating is a prepolymer with low polymerization degree and low molecular weight. Solution: when the curing speed is less than 0.5s, it is generally necessary to ensure that the high-pressure mercury lamp Jinan assay informs you of the classification of the electric valve actuator (according to its working characteristics, it can be divided into the following categories): the power is not less than 120w/cm; The lamp tube should be replaced in time. If necessary, add a certain amount of UV light oil curing accelerator to speed up 10. Flat sample clamping width: 70mm dry

III. The UV varnish on the surface of printed matter cannot be applied, and the selection of raw materials has laid a solid foundation for the safe use of special pigments. Advanced production technology and technology provide customers with rich and colorful products. At the same time, strict quality testing provides a guarantee for the safety of products. The main reasons are

1. The viscosity of UV varnish is too small and the coating is too thin

2. The content of ink middle note or dry oil is too high

2. The oil pressure system leaks oil seriously. 3. The ink surface has crystallized

4. There are too many anti sticking materials (silicone oil, powder spraying) on the ink surface

5. The glue roll line is too thin

6. Problems of construction technology (technicians are not very skilled)

solution: for products requiring UV glazing, corresponding measures should be taken during printing to create certain conditions: UV varnish can be appropriately thickened, and primer or special varnish formula can be used when necessary

although the variety of electrostatic powder coating is not as wide as solvent based coating, there are also many polymer resins that can be used as powder coating. Generally, it can be divided into thermosetting type and thermoplastic type

pearlescent pigment is a sandwich compound formed by depositing metal oxides (titanium dioxide or iron oxides) on natural mica flakes. The main components of mica, titanium and iron oxide are determined by predecessors after repeated tests and use, which are very safe for human body
