Modification and application of the suitable cleaning process for the surface plasma treatment of plastic printing products

Modification and application of the suitable cleaning process for the surface plasma treatment of plastic printing products

        Plasma surface treatment of plastic printing products, suitable cleaning process modification application:         Printing is an important way of information transmission and an effective means of beautifying products. The popularization and application of plastic products has promoted the development of plastic printing, and the development of plastic printing has made the application of plastic products more abundant and full. However, not all plastics have good natural printability. Some plastics are affected by ink adhesion due to non-polar molecular structure, low surface tension, or too smooth and stable chemical properties. Collectively referred to as difficult-to-print plastics, which require plasma treatment to be modified by an adaptive cleaning process to improve adhesion. Plasma treatment on the surface of plastic printing products         Introducing polar groups into the plastic surface, or increasing the surface tension, or increasing the surface roughness and using plasma treatment, this process provides a new way for the printing of difficult-to-print plastics. When considering ink wetting and adhesion, the contact angle is an important parameter. The contact angle is the tangent to the droplet surface from the three-phase boundary point where the liquid contacts the solid and the gas. The angle between the tangent and the solid surface is called the contact angle (the angle on the liquid side). The adhesion of printing ink is also related to the surface roughness of plastic products. Only when the surface roughness is appropriate can a great adhesion be obtained. The effective bonding area between the roughness of the ink and the plastic increases, and the ink can directly enter the micropores. When the solvent evaporates, the ink resin is mechanically embedded in the pores, forming many tiny mechanical connection points. Firmly "rivet" the ink on the plastic product.         However, too rough surface is also detrimental to ink adhesion, because too rough surface will make the wettability of the ink worse, fail to fill the micropores, cause adhesion defects, and decrease the adhesion. The critical surface tension means that when the surface of the plastic is completely wetted by the liquid (that is, the contact angle is exactly equal to zero), the surface tension of the liquid is defined as the critical surface tension of the plastic. The surface tension of various measuring liquids is known. If a certain measuring liquid can just completely wet the plastic, its surface tension is the critical surface tension of the plastic.         After the plasma treatment of the surface of the plastic printing product, the surface roughness, surface wettability and adhesion of the surface molecular structure of the plasma cleaning activation modification have obvious changes. Plasma treatment produces a large number of plasma particles, which directly or indirectly interact with the surface molecules of the plastic to produce polar groups such as carbonyl groups and nitrogen-containing groups on the surface molecular chains. At the same time, the surface molecular chains can be cross-linked and polarized charges can be generated.         After the plasma treatment of the surface of the plastic printing product, the surface roughness changes and becomes larger with the increase of temperature and processing time. This can be explained as the result of the oxidative degradation of the surface of the polymer and the interaction of the surface dielectric. The oxidative degradation products of molecules physically accumulate in the surface charge center, forming surface protrusions. Extending the treatment time and increasing the treatment temperature will reduce the charge center of the surface dielectric, but increase the strength, so that large and small protrusions are formed on the surface, and the surface roughness changes greatly. The increase in surface tension is mainly the result of the contribution of polar components, which is due to the increase of surface polar molecules due to the oxidation reaction of the plastic surface.

Atmospheric plasma surface treatment equipment explains the speed and width of material surface treatment

Atmospheric plasma surface treatment equipment explains the speed and width of material surface treatment

        Atmospheric plasma surface treatment equipment is used for the surface treatment of various materials. What is the processing speed and processing width? The processing width of the atmospheric pressure nozzle is about 20-80 mm. Compared with the activation process, the cleaning speed can reach tens of cm/ Seconds, if it is a folding box, it can reach 300m/min, and it can be customized according to needs.         Using atmospheric plasma surface treatment equipment plasma technology, the plasma is excited by high pressure; with the help of compressed air, the plasma is ejected from the nozzle. The plasma effect can be divided into two types: the plasma surface treatment device uses the active particles contained in the plasma nozzle to activate and precisely clean it. In addition, the activated spray can be accelerated by compressed air to remove adherent particles scattered on the surface. Changes in process parameters such as processing speed and distance to the surface of the substrate will have varying degrees of impact on the processing results.         An important step of plasma surface technology for atmospheric plasma surface treatment equipment is plasma cleaning. The dirt particles are converted into a gas phase through a chemical reaction with the ionized gas and an activated gas jet accelerated by compressed air, and then discharged through the continuous airflow through the exhaust pipe and the continuous airflow. When the copper oxide and hydrogen mixture gas-plasma are in contact, the reduction of the copper oxide occurs, and the oxide is chemically reduced to form water vapor. This gas mixture contains Ar/H2 or N2/H2, where the content of H2 is less than 5%. For atmospheric plasma, it consumes a lot of gas when it works.         What are the main advantages that plasma surface treatment equipment can bring us? Technology applied to the online process, for example, before encapsulating, bonding or coating continuous profiles and pipe fittings, use atmospheric plasma surface treatment equipment for plasma cleaning pretreatment. Partial surface cleaning can be performed by plasma surface treatment equipment without contact Other surface components, for example, do not touch other surface components on Al, Au and Cu pads (wire bonding) to improve the activated adhesion adhesion.

After online integration, plasma treatment can provide an ideal surface state for subsequent processes such as bonding, printing, or synthesis.         In the past, glass production generally used three basic colors: white, green, and brown. In order to make more exquisite glass silk-screen packaging, many products, such as glass bottles, beverage bottles, and perfume bottles, must be dyed, and beverage metal containers are also dyed. Decorative spray paint should be carried out to attract consumers.         For the above two kinds of packaging, high-standard surface spraying and general-purpose low-temperature plasma treatment equipment are required to provide particularly effective support for the above-mentioned spraying process. Nowadays, when people buy perfume, they don’t pay much attention to the fragrance, but often also pay attention to the packaging. Compared with the fragrance, its importance is not inferior. At present, the perfume glass bottles of major brands use plasma before printing. Technically processed.         Process advantages of plasma activation treatment of low temperature plasma treatment equipment:         1.
