(Summary description)Examples of surface modification of plastic, rubber, and silica gel made by Chengfeng Zhizhi Plasma Cleaner Brand: The energy of the particles in the plasma of the plasma cleaner is generally around a few to tens of electron volts, which is greater than the binding bond energy of polymer materials (a few to tens of electron volts), which can completely break the chemical bonds of organic macromolecules to form new bonds. Energy; but much lower than high-energy radioactive rays, only involves the surface of the material, does not affect the performance of the matrix. The electrons in the low-temperature plasma have high energy in a non-thermodynamic equilibrium state, which can break the chemical bonds of the surface molecules of the material and improve the chemical reaction activity of the material (stronger than the thermal plasma), and the temperature of the neutral particles is close to room temperature This provides favorable conditions for the surface modification of heat-sensitive high molecular polymers. The following is the plasma cleaning machine brand made by Chengfeng Zhizhi to explain the action process of plasma on various materials. Plasma cleaning machine performs surface modification treatment on plastic, silica gel and other materials: After low-temperature plasma surface treatment, the surface of the material will undergo many physical and chemical changes, or corrode roughness, or form a dense cross-linked layer, or introduce oxygen-containing polar groups to improve the hydrophilicity and adhesion, respectively. Properties, absorbability, biocompatibility and electrical properties. The results show that after plasma treatment of silicone rubber, N2, Ar, O2, CH4-O2 and Ar-CH4-O2 plasma can all improve the hydrophilicity of silicone rubber, and the treatment effect of CH4-O2 and Ar-CH4-O2 is better. Well, it will not degrade over time. Under suitable process conditions, using a low-temperature plasma cleaning machine to treat materials such as PE, PP, PVF2, LDPE, etc., can significantly change the surface morphology of the material, introduce a variety of oxygen-containing groups, and make the surface change from infinite and difficult to stick. In order to have a certain polarity, easy adhesion and hydrophilicity, it is conducive to the bonding, coating and printing of materials. Surface grafting using plasma technology: Plasma graft polymerization is used to modify the surface of the material, and a covalent bond is formed between the graft layer and surface molecules, which has good durability. The polyester fiber treated with glow discharge plasma is grafted and polymerized with acrylic acid. The water absorption performance of the modified polyester fiber is greatly improved, and its antistatic performance is also improved. The advantages of industrial application characteristics are simple process, convenient operation, fast processing speed, good treatment effect, low environmental pollution, and energy saving; Use plasma cleaning machine technology to modify plastic components to improve the wetting rate of plastics; Adopt plasma technology to reflect light on plastic window glass, car blinds, lamps, halogen sky lights, etc.; Polyester fiber is strong and durable, but has a compact structure, poor water absorption, and is not easy to dye. Low-temperature nitrogen plasma is used to initiate acrylamide graft modification to polyester fabric, so that the dye uptake and dyeing depth of polyester fabric after grafting can be improved. The hydrophilicity is significantly improved; Plasma cleaner surface treatment for medical materials can introduce amino groups, carbonyl groups and other groups, and the grafting reaction of biologically active substances with these groups can be fixed on the surface of the material; Industrial: assembly bonding, camera module, headset bonding, mobile phone back cover baking, mobile phone cover processing.
