  Effect of plasma surface treatment on surface modification Plasma surface treatment  is to etch the surface and generate free radicals, but when the material contacts the air, the free radicals on the surface will continue to react with the active gas in the air and generate polar groups. The type of gas plays a decisive role in the state of the plasma, and it directly affects the modification method and result of the surface of the polymer material by the plasma. Plasma surface treatment generally uses non-polymeric gases, including non-reactive gases and reactive gases. Non-reactive gases refer to inert gases such as He and Ar. When the plasma of this type of gas acts on the material, the inert gas originates from and does not combine with the polymer chain. Plasma surface treatment is to etch the surface and generate free radicals. , But when the material contacts the air, the free radicals on the surface will continue to react with the active gas in the air to produce po...

  The   plasma surface treatment machine   uses plasma to achieve effects that conventional cleaning methods cannot achieve. Plasma is a state of matter, also called the fourth state of matter, and it is not the standard three states of solid, liquid and gas. The plasma surface treatment machine uses the properties of these active components to treat the surface of the sample to achieve cleaning, coating and other purposes. How to treat the plasma surface treatment machine?  Common plasma surface treatment effects use contact angle measuring instruments, dyne pens, and surface energy test inks. The contact angle measuring instrument is currently the most common and industry-recognized testing method for evaluating the effect of plasma surface treatment machines. The test data is accurate, the operation is simple and convenient, the repeatability and stability are high. The principle is to titrate a certain amount of droplets on the surface of a solid sample through t...

  Domestic cold glue machine advantage   1. The price advantage, compared with the  cold glue machines  of major foreign brands, our domestic price is lower than that of foreign ones with the same configuration. In the past, when most printing and packaging factories received orders, when their existing machines could not meet the production requirements, they had only two options, either to purchase expensive foreign glue spray systems, or to discard the order. Reed's glue spraying machine can be sprayed accurately when it is produced. The glue head can be suitable for any high-speed production. The working frequency of the glue head is 1 time in 0.02 milliseconds. The glue spraying machine controller is powerful and easy to operate.

Principle of vacuum plasma cleaning Plasma is a state of existence of matter. Generally, matter exists in three states: solid, liquid, and gas, but in some special cases, there is a fourth state, such as the substance in the ionosphere in the earth’s atmosphere. The following substances exist in the plasma state: electrons in a state of high-speed motion; neutral atoms, molecules, and groups of atoms (radicals) in an activated state; ionized atoms and molecules; unreacted molecules, atoms, etc., but ...

  Plasma, the fourth state of matter, is an ionized gaseous substance composed of atoms deprived of some electrons and positive and negative electrons generated after atoms are ionized. Its energy range is higher than that of gas, liquid, and solid matter. There are electrons, ions and neutral particles with a certain energy distribution. When they collide with the surface of the material, they will transfer their energy to the molecules and atoms on the surface of the material. A series of physical and chemical processes. Its function on the surface of the object can achieve ultra-clean cleaning of the object, surface activation, etching, finishing and plasma surface coating. (1) Etching on the surface of the material A large number of active particles in the plasma, such as a large number of ions, excited molecules, and free radicals, act on the surface of a solid sample to remove the original contamination The surface becomes rough, forming many tiny potholes, increasing the spe...

  Due to the low surface tension of most plastic materials, many designs in the past tended to adapt to the use of materials. Nowadays, as long as the surface can meet the requirements of spraying or bonding after a certain plasma surface treatment, it can be used first. This material. In recent years, cost and material use characteristics have become the dominant factors in product design, which has caused automakers to begin to focus on more plastic varieties. At present, PP, PC, ABS, SMC, various elastomers and various composite materials have been widely used in automobile manufacturing. In this case, it is necessary not only to deal with the mutual adhesion problem between the same material parts, but also to solve the mutual adhesion problem between different material parts. However, the past plasma surface treatment methods are obviously difficult to meet this processing process. Requirements. In terms of  plasma surface treatment  effect, among all the current sur...
