(Summary description)Plasma cleaner pretreatment DLC tungsten carbide aspherical mirror carbon film and wood wetting effects: Plasma cleaning machines are widely used in the activation and modification cleaning of precision electronics, semiconductor packaging, automobile manufacturing, biomedical, optoelectronic manufacturing, new energy, textile printing and dyeing, packaging containers, household appliances and other industries. The wettability of wood pulp is an important interface property that characterizes the difficulty and effect of wetting, spreading and bonding on the surface of wood pulp when certain liquids (water, binders, oxidants and cross-linking agents, etc.) are in contact with wood pulp. Plasma pretreatment is of great significance to the interface of wood pulp and various modification processes. The tungsten carbide aspherical mirror carbon film on the DLC surface is cleaned by a plasma cleaning machine, and the plasma cleaning machine is very effective in cleaning the tungsten carbide aspherical mirror carbon film on the DLC surface. After the aspheric mirror surface DLC film is treated by the plasma cleaning machine, the removal effect is good, and the film residues such as dirty, messy and miscellaneous surfaces can be removed. Wood pulp is a natural high molecular polymer, which not only has dual properties of biology and physicochemical, but also is a non-uniform anisotropic material. Its surface structure and chemical composition will affect the glue performance of wood pulp, thereby affecting wood The overall strength, toughness, durability and other properties. Test method: Put the wooden veneer on the lower tray of the plasma cleaning machine, then place it in the reaction chamber, and close the chamber door. Then turn on the vacuum pump, evacuate, pump to the corresponding vacuum value, turn on the gas required for plasma treatment, and press the start button to perform plasma treatment. Determination. Because plasma treatment is time-sensitive, the treated samples must be tested for surface contact angle in the shortest possible time. Chengfeng Zhizao has developed small plasma cleaning machines for universities and scientific research units. An experimental platform developed by scientific research institutions and corporate laboratories, or creative small-scale production enterprises. It has rich information in customer use, application demand analysis, and many years of experience in design and manufacturing. Small multifunctional plasma surface treatment equipment is a huge investment, both in design concept and in choice of accessories. The company can provide corresponding accessories according to the different requirements of customers, with surface plating (coating), etching, plasma chemical treatment, powder plasma treatment and other functions, and at the same time achieve conventional performance. RESULTS AND ANALYSIS After pretreatment with a plasma cleaner, the contact angle decreased from 113.8° to about 50° after about 3 minutes. With the prolongation of the treatment time, the change of the contact angle tended to be stable or slightly increased, especially when the treatment time exceeded For more than 7 minutes, the wood surface is greatly affected by high-energy electrons, the ions are relatively uninterrupted, the energy accumulation is large, and the local area has too deep etching. , carbonyl and other chromophoric groups, and the high-energy plasma discharge increases the temperature of the wood surface, which is easy to cause local color to darken and cause carbonization. Low-temperature plasma discharge treatment is performed on the wood, and the treatment time is preferably 3 minutes.
