Ink is an important material used for packaging materials printing, it will be printed through the pattern, text performance in the substrate ink includes the main components and auxiliary components, they are evenly mixed and repeatedly rolled into a viscous gelatinous fluid. Ink is used in the printing process to form the graphic information material, so the role of ink in printing is not trivial, it directly determines the printed image of the tone, color, clarity and so on. In printing we need to understand the composition of ink and ink classification.
Laser cleaning is a new type of environmentally friendly cleaning methods, it can not only remove metal surface oxides, but also able to remove non-metallic workpieces, such as ceramics, plastics, etc., but also able to remove dust on the surface of the workpiece, oil, floating rust, coatings, etc., and will not hurt the workpiece itself.
It is not easy to modify the ink after it dries. Since the ink is printed on corrugated paper, if you use chemical reagents to wipe it off, the surface of the corrugated paper will be wet and wrinkled. If you use adhesive tape to remove the corrugated paper for reprinting, the layer of paper on the surface of the corrugated paper will also be glued off, damaging the corrugated paper. If there are a large number of printing errors that can't be corrected, you can only throw them away, which is undoubtedly a waste of money. Laser cleaning, on the other hand, can quickly clean the printing ink from the corrugated paper without harming the surface of the corrugated paper, making the corrugated paper ready for secondary use.
Advantages of laser cleaning:
1. Laser cleaning is a "green" cleaning method that does not require the use of any chemicals or cleaning fluids. The waste material is basically a solid powder that is small in size, easy to store, and can be recycled, so it can easily solve the environmental pollution problems caused by chemical cleaning.
2, the traditional cleaning methods are often contact cleaning, cleaning the surface of the object has a mechanical force, damage to the surface of the object or cleaning medium attached to the surface of the object being cleaned, can not be removed, resulting in secondary pollution, laser cleaning of non-abrasive and non-contact so that these problems are solved.
3, the laser can be transmitted through the fiber optic transmission, and robots and robots to match, easy to achieve long-distance operation, can clean the traditional method is not easy to reach the parts, which in some dangerous places can ensure the safety of personnel;.
4, laser cleaning can remove various types of pollutants on the surface of various materials, to achieve the cleanliness of conventional cleaning can not be achieved. And also can not damage the surface of the material in the case of selective cleaning of the surface of the material pollutants.
5,Laser cleaning is highly efficient and saves time.
