The pretreatment of industrial plasma cleaning equipment provides good adhesion to the surface of the material:
Good adhesion is extremely critical. The adhesion of the surface plays a decisive role in the bonding process. If an adhesion promoter (primer coating) or solvent-based process is used, it is not environmentally friendly or costly. After pretreatment and fine cleaning of the adhesive surface by industrial plasma cleaning equipment, users can use solvent-free UV adhesives and water-soluble materials.
Due to the effective activation of the surface of industrial plasma cleaning equipment, incompatible substances can also be bonded together, so that the adhesive can be attached to surfaces that are difficult to bond (such as non-polar plastics). The chemical primer pretreatment or surface polishing and washing becomes unnecessary. This also avoids the emission of volatile hydrocarbons (VOC) during the production process.
Modern products require high-quality coatings to peel off, which makes users very annoyed, and it can even cause some high-tech products to malfunction. Especially the automobile manufacturing industry is inseparable from the coating and painting process, with laser marking switches, bright decorative strips, cover plates, scratch-resistant display screens, reflective baffles, grids or sundries in ventilation devices The handles of the box need to be coated and painted.
The plastic parts inside the car now also use high-cost coatings. Plasma technology of industrial plasma cleaning equipment can be used as pretreatment for bonding and coating in this field. This process has been applied in BMW and Rolls-Royce cars.
The painting of mobile phone shells has extremely high requirements on the surface: the paint surface must be flawless, and the overall surface clean and beautiful. A small dust particle that is almost invisible on the surface of the shell before painting will form unsightly bumps after painting, making it unacceptable for consumers. Static electricity is the main cause of dust adhesion.
The mobile phone supplier responded to this problem: installing industrial plasma cleaning equipment for mobile phone shells to achieve an ideal cleaning effect in the production process. Before painting, multiple rotating plasma spray guns clean the plastic surface efficiently, reducing the scrap rate from 12% to 2%.
Good adhesion ability allows cheap raw materials to be put into use. The plasma process introduced above can be easily combined with the existing processes to improve processes such as injection molding.
Today, this process allows cheaper materials to be used for two-component injection molding of soft and hard rubber.
In order to firmly bond normally incompatible plastics, plasma surface treatment technology can be used to replace expensive ABS/PC and thermoplastic polyurethane (TPU) composite injection molding with cheap polypropylene (PP). In the processing technology of multi-component composite materials of plastics and plastics and plastics and metals, the plasma process of industrial plasma cleaning equipment also has great potential in cleaning and improving bonding capabilities. This process can also be used for thermoplastic-thermoplastic bonding, thermoplastic-thermosetting plastic bonding, thermoplastic-silicone rubber bonding, etc.
