Application of low temperature plasma surface modification machine technology and equipment on materials

Low-temperature plasma surface modification machine technology equipment can be used to prepare hydrophilic substances, change the product surface value for printing use, after treatment and then use adhesives or ink can be very good to achieve the bonding effect, usually called plasma surface modification, this method is used to make the object become hydrophilic (wettability). A hydrophobic surface repels water and is considered non-wettable. Duck feathers, for example, are hydrophobic, and water flows over the surface rather than over the feathers.

Low-temperature plasma surface modification machine technology equipment

PTFE or plastic is often treated with low-temperature plasma surface modification machine technology equipment, so that the surface is more "wet-able", thus improving the adhesion and printing performance. This is a common purpose when we perform plasma cleaning.

Low temperature plasma surface modification

The low-temperature plasma surface modifier technology device actually changes the surface of the material by several layers of monolayer film, leaving free radicals on the surface and binding with glue or ink. This is especially useful when bonding different surfaces, such as plastic or metal. The surface is different, the binder is different; This makes it difficult to find a suitable adhesive. Look for connections that use plasma to change the surface, leaving extra electrons on the plastic or rubber surface. This can make the surface adhesion, strength greatly improved.

Plastic surface is smooth, usually printed or adhered to other materials, such as plastic or metal bonding treatment is not strong. When these smooth surfaces are treated with plasma, the added surface allows for direct printing without coating. This effect is quite brief, ranging from a few hours to a few days, and there is enough time to complete the process of processing the material.

Low-temperature plasma surface modification machine technology, such as vacuum plasma treatment, has more advantages than pneumatic plasma technology. Negative pressure plasma system makes the action of plasma longer and provides excellent surface improvement treatment. Atmospheric plasma systems are usually easier to install on assembly lines, or to handle large products in small areas.
