Plasma film deposition technology

Plasma polymerization medium film can protect electronic components, using plasma deposition conductive film technology to protect electronic circuits and equipment from damage caused by static charge accumulation, plasma deposition film technology can also be used to make capacitor components. It can be widely used in electronic industry, chemical industry, optics and other fields.   Plasma volume silicon compound, SiOxHy is produced using SiH4+N2O(or Si(OC2H4)+O2). The air pressure is 1~5 ttos (1 ttos ≈133 pa) and the power is 13.5MHz. SiH4+SiH3+N2 was used for Si3N4 deposition at 300℃ and the deposition rate was 180 angm/min. The amorphous silicon carbide film is obtained SixC1+x: H by adding a carbon containing co-reactant silane, and x is Si/Si+C ratio. Hardness over 2500 kg/mm.   The selective osmosis and reverse osmosis membranes are prepared by depositing a thin polymer film on a porous substrate by plasma, which can be used to separate gases in the mixture, ions and water. It can also be combined with ultra-thin film layer to adapt to different selectivity, such as molecular size, solubility, ionic affinity, diffusivity, etc. In the conventional method, 0.5 mm film was deposited on the carbonate - silicon copolymer substrate, the permeation ratio of hydrogen to methane was 0.85, and the permeability of methane was higher than that of hydrogen. When the plasma deposited benzoyl cyanide monomer on the substrate, the ratio increased to 33, and the separation efficiency was greatly improved. Reverse osmosis membrane can be used for desalting seawater. When the water flow rate is lower than a certain threshold, the desalting effect is better. The polymer film has good permeability resistance, such as olefins, heterologous aromatics and aromatic amines.   The film prepared by plasma deposition technology can be used for optical elements, such as anti-reflection film, moisture-proof film, anti-wear film, etc. Plasma can be used in integrated optics to deposit a stable film according to the required refractive index and connect it to each element in the optical path. Such films lose 0.04 decibels of light per centimetre.

Application of plasma surface treatment in plastic and rubber industry

Due to the non-polarity of polypropylene, PTFE and other plastic materials, in industrial applications, it will be difficult to bond the surface of some plastic products. In the absence of plasma surface treatment, the printing, bonding, coating and other processes have very poor effect, or even cannot be carried out. Some processes use some chemicals to treat the surface of these rubbers and plastics in the production process, which can change the adhesive effect, but this method is difficult to master, the chemicals themselves are toxic, the operation is very complicated, the cost is high, and the chemicals have an impact on the original excellent properties of rubber and plastics materials. Plasma surface treatment technology is used to treat these materials, so that these materials can play the role of structural surface under the bombardment of high speed and high energy plasma. Meanwhile, an active layer is formed on the surface of the materials to enable rubber and plastic to carry out printing, bonding, coating and other operations.   Plasma surface treatment for plastic surface treatment:   The study found that most plastics have low surface tension, such as polyethylene (PE) and polypropylene (PP), which have a surface tension of 31 Dyne,The surface tension of polyester (PET) and PVC (PVC) is 39 Dyne,Nylon (PA) is 41 Dyne.   In order to meet the requirements of printing and bonding, the surface tension must reach the dyne value of 38, 38, 52, 48, 56 or even higher. Until the invention of off-surface processing machines, many plastic process designs preferred materials, which could meet the requirements of spraying or bonding processes, before the use of such materials, because of the high cost of materials, manufacturing costs have been high. Since the 1980s, with the extensive application of plasma surface treatment, manufacturers began to focus on more plastic varieties, PP, PC, ABS, SMC all kinds of elastomer and a variety of composite materials have also been fully developed. Plasma surface treatment not only solves the adhesion between the same material components, but also solves the adhesion between different material components. In the new process, the traditional surface treatment (such as polishing machine, polishing effect is limited) and environmentally friendly water-based coating treatment (some treatment only about 40mN/m, the material can not be completely wetted) have been impacted. Although fluoride treatment has a good effect, a lot of harmful gases will be produced in the process of use, which often greatly increases the cost of waste gas treatment for manufacturers. Plasma surface treatment is an economical and environmentally friendly surface treatment process, the treated material surface can easily reach 65 because of the surface tension, to meet many high standards of process requirements. It is the use of electromagnetic discharge to produce plasma, jet to the surface of the material, thus greatly improving the surface energy of plastic products.   Plasma surface treatment for rubber:   Rubber and plastics are non-polar, not under the state of surface treatment, its printing, bonding, coating, and other functions are very poor, or even can not be carried out. In the surface treatment process of some rubber, the use of some chemicals, although it can improve the bonding effect, but this method is complex to operate, chemicals themselves toxic, very careful use, and the purchase cost is high, and the chemicals will destroy the rubber material part of the good performance. Plasma-surface treatment is used for rubber surface treatment, so that these materials can play the role of structural surface to a great extent under the bombardment of high speed and high energy plasma, and at the same time, an activation layer is formed on the surface of the material, so that rubber can be used for printing, bonding, coating and other operations. Using plasma technology to treat rubber surface, simple operation, no harmful substances before and after treatment, good treatment effect, high production efficiency, low operating cost.

Silicon rubber plasma processor surface treatment

Polymethyl methacrylate has been used as a contact lens material since the 1940s. PMMA is still widely used because of its high refractive index, suitable hardness and good bioaffinity. However, PMMA has poor hydrophilicity, which can cause long-term pannus closure and discomfort to the wearer. At the same time, its oxygen permeability is poor, serious can lead to complications. If the above shortcomings of PMMA can be overcome, its efficiency can be greatly improved. Plasma polymer of acetylene, nitrogen and water was used to coat PMMA lens surface, which can improve the hydrophilicity of material and reduce adhesion of corneal epithelial cells. The addition of organosiloxane to the polymer sandwich can improve the permeability of the material, but due to its inherent hydrophobic nature, siloxane will reduce its moisture retention. The surface hydrophobic problem of silicon-containing polymer can be treated by glow discharge generated by vacuum plasma cleaner. PMMA through vacuum plasma cleaning machine and polysiloxane binding material surface treatment, can reduce the surface carbon content, increase the oxygen content of PMMA, improve its moisture.   Contact lenses made of silicone rubber are called "soft" lenses. Silicone rubber has good permeability, soft texture, good mechanical elasticity, durability and other characteristics. Its disadvantages are too large viscosity, hydrophobic, liquid easy to permeate. Coating the silicone rubber with a layer of methane film can improve its moisture retention, reduce viscosity, reduce the permeability of liquid, and maintain its air permeability.   PMMA is a material commonly used for intraocular lens transplantation, but its contact with corneal epithelial cells can lead to damage of corneal epithelial cells. Hydrophilic monomers, such as hydroxyethyl isobutenate or N-vinyl pyrrolidone, can be deposited on the PMMA surface by grafting or irradiation with a vacuum plasma cleaning machine. Static "contact tests" between the cornea and lens of rabbits showed that PMMA surfaces without plasma treatment could cause 10-30% cell damage, while PMMA/HEMA composite surfaces could cause about 10% cell damage, and PMMA/NVP composite surfaces could cause less than 10% cell damage. Plasma deposition on C3F8, HEMA and NVP all significantly reduced corneal cell damage. In addition, adhesion ability of NVP membrane on PMMA surface was significantly lower than that of PMMA.   Plasma treatment is usually a plasma reaction that causes changes in the molecular structure of the surface or substitutions of the surface atoms. Even in the inert environment of oxygen and nitrogen, plasma treatment can produce high active groups at low temperature. In the process, the plasma also emits high-energy ultraviolet light and produces fast-moving ions and electrons that break the polymer's bonds and generate the energy needed for chemical reactions on the surface. The bulk properties of the polymer remain unchanged only if a few atomic layers are involved in the chemical process on the surface of the material. In addition, the possibility of thermal damage and deformation is avoided due to the low temperature of plasma treatment. Selecting appropriate reaction gas and process parameters can promote some specific reactions and form special polymer attachments and structures.

Functions and USES of plasma cleaning machine

As its name suggests, the plasma cleaning machine is a cleaning equipment, if only from the literal meaning of understanding the plasma cleaning machine function will be a bit one-sided. Because the plasma cleaning machine can not only clean the surface cleaning role, but also a series of applications such as surface modification activation. When it comes to the role of the plasma cleaning machine, can not say magic plasma, it is no exaggeration to say that the role of the plasma cleaning machine can be said to be the role of the plasma.   To clearly understand the function and purpose of the plasma cleaning machine, we must begin by understanding the plasma. So, what is a plasma? Plasma is a state of matter, we know that the state is usually solid, liquid, gas, but in some special cases, can also be a fourth state, such as the surface of the sun, and the earth's atmosphere in the ionosphere material. This state is called the plasma state, or the fourth state of matter.   The following substances are present in plasma: high-speed electrons, excited neutral atoms, molecules, and atomic groups (free radicals); Ionized atoms, molecules, and molecules dissociated by ultraviolet light; An unreacted molecule, atom, etc., but a matter as a whole remains electrically neutral.   The plasma cleaning mechanism mainly relies on the "activation" of the active particles in the plasma to remove the surface stains. In terms of mechanism, plasma cleaning generally includes the following processes: excitation of inorganic gases into plasma; Adsorb the gaseous phase to the solid surface; The adsorption group reacts with the solid surface molecule to form the product molecule. The molecule of the product is resolved into the gas phase. Get the reaction residue off the surface.   The general functions of plasma cleaning machine are as follows: 1. Plasma surface activation/cleaning; 2. Improved bonding ability after plasma treatment; 3. Plasma etching/activation; 4. Plasma rubber removal; 5. Plasma coating (hydrophilic and hydrophobic); 6. Strengthen the state character; 7. Plasma coating; 8. Plasma surface modification, etc.

Glass plasma surface treatment

Glass has been used as a material for centuries. Due to the chemical inertia of the glass and its stable properties under the influence of the environment, the glass substrates are cleaned and dried by conventional cleaning methods, so it is difficult to completely remove the foreign bodies adsorbed on the surface. In addition, the surface will be exposed to the air during transportation and handling, which will inevitably adsorb the ambient gas, water vapor and particles. If left untreated, it will lead to insufficient binding force between the film layer and the substrate, resulting in pinholes and particles. After being cleaned and treated by plasma surface treatment machine, the glass material can enter into the next process immediately. Therefore, plasma surface treatment of glass is a stable and effective process.   Plasma surface treatment machine modification, the processing technology of glass has simple equipment, low raw material consumption, low cost, high value-added products, glass coating, adhesive, membrane process was optimized, the low temperature plasma surface treatment machine modified material has been widely used in capacitive, resistive touch screen mobile phone, such as some need to finish machining of glass. After plasma treatment, the glass can reach a point of 72 dyne or even higher, and the water drop Angle can be reduced to less than 10 degrees. It solves the difficulties of glass bonding, printing, electroplating and other problems.   In the plasma, as the glass substrate is bombarded by the charged energy particles (electrons) in the plasma, the ambient gas, water vapor and dirt adsorbed on the surface of the substrate are first bombarded to activate them, make the surface clean and improve the surface energy. When the substrate is deposited, the film atoms or molecules are immersed in the surface to increase van der Waals force. The second is that the surface of the glass substrate is impacted by the charge particles (electrons). Under such impact, many pits and pores will be formed on the surface of the glass substrate. In the deposition process, atoms or molecules in the film enter into these grooves and pores, thus generating mechanical locking force. In addition, the coarsening of the substrate surface increases the actual surface area, which is beneficial for increasing van der Waals forces (intermolecular forces), diffused adhesion, and electrostatic adhesion, thus increasing the total adhesion.   After plasma surface treatment of glass, the surface of the substrate can be cleaned and activated, and the surface can be improved. It can not only effectively remove the environmental gas molecules, water vapor and pollutants adsorbed on the substrate, but also form a clean and activated micro rough surface on the surface of the substrate, and avoid secondary pollution.
