The uPVC Profile on the market is mainly white, but the demand for color in the market is great. With the advancement of technology, many process methods have appeared. Various methods such as extrusion, spraying, laminating, etc. Jinan lumei plastic steel profile manufacturer shares the coloring method of colorful plastic steel profile with you.
The overall colorful aluminum profile means that in the production of uPVC Profile, color paste is added in the seasoning process to make it colorful. This kind of method is generally that the external environment of the aluminum profile contains hue. In the overall coloring method, the color paste to be colored is mixed into the compound fertilizer granules of the pvc profile or configured as a liquid to be added from the air outlet of the extruder to obtain the coloring method of the overall colorful pvc profile.
Its advantages are: the project investment is small, the processing process is convenient, and the failure rate is low; the defect is: the heat distortion temperature is low, very dark brown, dark brown aluminum profile, because of the endothermic reaction, its surface temperature is It may be close to the application temperature limit of the aluminum profile, which often causes problems such as deformation and cracking of the aluminum profile.
In addition, this kind of coloring method is also very easy to cause uneven color or fading. In addition, the color paste has certain corrosion to the machinery and equipment, so this kind of coloring method is rarely used.
Surface spraying of uPVC Profile is also a simple method, which stipulates that in the production process of plastic steel profiles, degreasing must be carried out before spraying to ensure the adhesion of the paint and prevent the paint from falling off. The color of the paint can be selected independently, and the adhesion of the paint and the previous solution and the quality of the manufacturer and its production process are very harmful.
Co-extrusion processing technology is a processing technology that is used in many applications at this stage. In this method, the colorful co-extrusion layer and the surface layer of the aluminum profile are fused together during the processing of aluminum profiles. The color tone is only produced on the surface of the aluminum profile, and the color tone is reliable. The production processing room must upgrade a small and medium-sized co-extruder with a single-screw extruder. The raw materials used for co-extrusion are colored plexiglass plates PMMA, etc. The defect of co-extruded aluminum profile is that it is not easy to repair after partial damage.
The two-color co-extrusion method is an excellent and perfect production process for the production of colorful pvc profiles in the world today. The two-color co-extrusion method is actually a composite technology in the entire process of the extrusion of the general milky white aluminum profile.
Macromolecule materials generally include colorful organic glass plates, ternary composition ASA and colorful PVC plastic masterbatches. The two-color co-extrusion method must be equipped with a co-extrusion machine, in which the mold design and production are very complicated, and each aluminum profile must have a set of molds, and the one-time capital investment is relatively high. In addition, it is very difficult to recycle non-conforming products and waste materials. In addition, not only must high-quality impact-resistant PMMA powder, but also a variety of colors must be reserved. For this reason, its application and development trend are also limited.
The plan of sub-film processing technology to make the plastic steel profile colorful has been widely used in the specific sales market. There are many options for the color of the film material, which has a good anti-aging effect and can achieve good adhesion. The production and processing method is to solve first, remove the waste and oil stains on the surface of the aluminum profile, apply the glue on the laminating machine, and go through several pressings of the roller, so that the film layer and the surface of the aluminum profile are inseparably bonded together.
There are more and more applications of colored plastic steel. With the advancement of science and technology, it is expected that better technology will be applied to plastic steel profile products to achieve richer colors, lower costs and longer service life.
Jinan lumeiu uPVC Profile Co., Ltd. is based on digesting and absorbing advanced plastic steel profile manufacturing technology and technology at home and abroad, focusing on health and environmental protection, and providing users with a safe and healthy door and window profile system.
