Information
1. Car interior
With the development of economy, consumers have higher and higher requirements for automobile performance, such as automobile appearance, operating comfort, reliability, and durability. In order to meet the requirements of consumers, automakers pay more attention to detail optimization and improvement when producing cars, such as
(1) The instrument panel is treated before flexible polyurethane (PU) coating
(2) The control panel is processed before sticking to the table
(3) Pre-treatment of internal PP parts for planting tape
(4) Treatment of automobile door and window seals
The coating effect of instrument panel or control panel without any treatment before is very poor, not abrasion-resistant, and easy to paint. Although chemical treatment can change the coating effect, it also changes the performance of the instrument panel and other substrates. , Which reduces its strength. At present, many manufacturers have used plasma technology to treat these substrates. Through plasma bombardment, the micro-level activity of the material surface is enhanced, which can significantly improve the coating effect. According to experiments, it is necessary to select different process parameters to process different materials with a plasma cleaner to achieve better activation effects.
2. Engine oil seal
The engine crankshaft oil seal prevents the engine oil from leaking from the engine and prevents foreign matter from entering the engine. The crankshaft oil seal is one of the engine parts and comes into contact with the engine oil at high temperatures. Therefore, materials with excellent heat resistance and oil resistance are required. At present, PTFE materials are commonly used in cars. With the continuous improvement of automobile performance requirements, more and more manufacturers use this material, and its application prospects are very broad. PTFE material has excellent performance in all aspects, high temperature resistance, corrosion resistance, non-sticking, self-lubricating, excellent dielectric properties, and low friction coefficient. However, the surface activity of untreated PTFE material is poor, and its one end is connected to the metal. The bonding between the two is very difficult, and the product cannot meet the quality requirements. In order to solve this technical problem, we must try to change the surface properties of PTFE (polytetrafluoroethylene) and metal bonding without affecting the performance of the other side. Although solution treatment in industry can improve the bonding effect to a certain extent, it changes the performance of the original PTFE. Experiments have proved that after bombarding the PTFE surface to be bonded with plasma, its surface activity is significantly enhanced, and the bond with the metal is firm and reliable, which meets the requirements of the process, while the other side maintains the original performance, and its application is also More and more widely recognized.
3. Ignition coil
With the development of the automotive industry, its performance requirements in all aspects are getting higher and higher. Ignition coils can increase power. The obvious effect is to increase the torque at low and medium speeds when driving, eliminate carbon deposits, better protect the engine, extend the life of the engine, reduce or eliminate engine resonance, fully burn fuel, reduce emissions, etc. Features. To make the ignition coil fully play its role, its quality, reliability, and service life must meet the standards. However, there are still big problems in the current ignition coil production process. After epoxy resin is poured outside the ignition coil skeleton, the skeleton is in The front surface of the mold contains a large amount of volatile oil stains, which causes the bonding surface of the skeleton and the epoxy resin to be unreliable. When the finished product is used, the temperature rises at the moment of ignition, which will generate bubbles in the gap of the bonding surface, which will damage the ignition coil. There will also be explosions.
After the ignition coil skeleton is treated with plasma, it can not only remove the non-volatile oil on the surface, but also greatly improve the surface activity of the skeleton, that is, it can improve the bonding strength of the skeleton and the epoxy resin, avoid the generation of bubbles, and improve the enameled wire after winding. The welding strength of the contact with the frame. In this way, the performance of the ignition coil in all aspects of the production process has been significantly improved, and the reliability and service life have been improved.
