What is plasma?

Plasma is commonly referred to as the fourth state of matter, with the first three states being solid, wave body, and gas, which are common around us. A certain amount of plasma is composed of a mixture of charged particles and neutral particles (including atoms, ions, and free particles). High physical conductivity reacts with electromagnetic force.

When the temperature rises, substances will change from solids to liquids, and liquids will turn into gases. When the temperature of a gas increases, gas molecules will separate into atoms. If the temperature continues to rise, electrons around the atomic nucleus will detach from the atom and become ions (positive charge) and electrons (load).

The application advantages of plasma cleaning machine in the field of plastic printing!

Under normal circumstances, various plastic materials such as spraying, printing, electroplating, and bonding need to be cleaned with a plasma cleaning machine before pre-treatment. What is the effect! Before spraying, printing, electroplating, and bonding, surfaces such as PP, PVC, PET, PC, and PE can be activated and modified by plasma cleaning, and surface pollutants can be removed.

Plasma processing machines can be widely used in plastic, silicone, rubber, metal, mobile phones, computers, toys and other plastic casings for pre-treatment before printing and painting, thereby improving surface adhesion; For example, plastic cosmetic bottles are pre treated with a plasma cleaning machine before printing, which can improve surface adhesion, prevent text from falling off, and improve product quality.

Plasma formation: Plasma is formed by electrically ionizing gases (such as oxygen or air), resulting in plasma, electrons, and neutrality.

Plasma cleaning machines can decompose and remove organic pollutants and other residues, increase surface energy, make them more hydrophilic, and more easily accept adhesives, coatings, and coatings. Plasma cleaning machines can change surface chemical properties, create new functional groups, and enhance bonding advantages. 

Plasma treatment enhances the adhesion of plastics to other materials. In medical applications, low-temperature plasma treatment is used to prepare the bonding, coating, and printing of plastic surfaces for cleaning and activating bonding and coating surfaces in electronic manufacturing. Plasma treatment is used for coating, coating, and bonding plastic surfaces in various industries.

The atmospheric pressure plasma cleaning machine of Guangdong Zhenyi Intelligent Equipment Co., Ltd. uses atmospheric pressure plasma and is suitable for large-scale applications. The effectiveness of plasma treatment depends on factors such as gas type, pressure, and treatment time. Different types of plastics may require different plasma treatment parameters, and plasma treatment usually only affects the surface layer of the plastic, maintaining the overall material properties unchanged.

The atmospheric plasma cleaning machine has the ability to etch, activate bond energy, and crosslink to form new functional groups. There are a large number of ions, excited molecules, free radicals, and other active particles in the plasma. The particle energy in the plasma is between 0-20eV, while most of the bond energy in polymers is between 0-10eV. 

The free radicals in the plasma form a network like crosslinking structure with these bonds, greatly activating surface activity. Complex chemical reactions occur on the activated material surface, introducing new functional groups such as alkyl, amino, carboxyl, etc. These functional groups are active groups that can significantly improve the surface activity of the material.
