Plasma surface treatment of automotive materials in automotive plasma processors:
        Application of automotive plasma processor to surface treatment of automotive materials can not only improve the bonding quality, but also after plasma cleaning, the surface of the material will also obtain new characteristics, so that the general material can obtain better surface processing performance.
        After plasma surface treatment, the surface of the material gets new characteristics, so that ordinary materials get the surface processing performance that the original special materials have. In addition, the plasma cleaning effect eliminates the need for solvent cleaning, which is environmentally friendly and saves cleaning and drying time.

Plasma surface treatment

Automotive plasma processor
        Automobiles have higher and higher requirements for sealing materials, and the demand for sealing rubber strips is also increasing. New technologies and new materials continue to appear, so processing technologies will become more and more complex. In recent years, with the continuous development and maturity of thermoplastic elastomer technology, new thermoplastic elastomer materials such as TPO and TPV have been used more and more widely in automotive sealing strips. The material combines the excellent properties of elastomers and plastics, which is convenient for processing and recyclable, and is gradually replacing EPDM products. The ordinary door seal is composed of a co-extruded solid core bracket and a sponge rubber tube seal. The sponge part has a sealing function after being compressed by the car body door frame. However, when driving at high speed, the external air pressure may exceed the great sealing force provided by the sponge body, resulting in sealing failure.
        In order to solve this problem, some companies have designed a new type of sealing profile to introduce magnetic rubber into the sponge body, that is, apply a magnetic coating on the sponge body or add magnetic moldings to directly magnetically attract the metal frame of the fuselage. Thereby increasing the sealing performance of the sponge body. Because the surface tension of these automobile sealing rubber strip materials is very low, when using flannel, flocking, PU, ​​silica gel and other coating processes, the materials are not easy to bond. In the past, manual segmented grinding processes were used to increase the surface roughness of the rubber strips. Applying primer again, the polishing process is time-consuming and labor-intensive, and the production efficiency is low. It cannot cooperate with the extrusion equipment for online processing, which is likely to cause secondary pollution, high cost, and low product qualification rate. Nevertheless, with the continuous improvement of product requirements, its grinding process has been unable to meet the requirements of the Ministry and European standards for automobile production.
        Plasma processor is used for the surface treatment of automotive sealant strips:
        Low-temperature plasma processor plasma technology is used for surface treatment of various automobile sealing strips. After testing, the surface energy can reach >80dynes/cm. The process of polishing or coating polyester can be removed. No primer is required, and it can be extruded or pressed. The speed of the flocking machine realizes online processing, increases productivity, reduces costs, does not damage the surface of the tape, and meets the environmental protection requirements of coating water-soluble glue. Jet low-temperature plasma has been applied to the door frame sealing strip, door head, window guide groove, window edge, front and rear windshield, front and rear cover sealing strips of cars and automobiles.
        After being treated by a plasma processor, the hydrophilicity of the glass is improved, and it is used in medical equipment, which is conducive to the adhesion and growth of cells. In the glass bottle labeling process, the plasma surface treatment machine is used for the pretreatment of the glass bottle body. Through the pretreatment, low-cost and environmentally friendly water-based glue can be used to seal the label.
