Examples of surface modification of plastic, rubber, and silica gel made by Chengfeng Zhizhi Plasma Cleaner Brand

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. Display industry: TP patch. Bonding in the automotive industry: car lights, steering wheels, EPDM seals, windshields, automotive electronics, automotive decorative parts.

Application of plasma plasma cleaning machine low temperature plasma activation technology in surface treatment of materials

Application of plasma plasma cleaning machine low temperature plasma activation technology in surface treatment of materials: In recent years, in order to improve the surface viscosity of organic materials, such as the treatment of rubber surfaces, the plasma plasma cleaner technology has been reduced and miniaturized, and the "hot arc" has been changed to "cold arc" and developed into a jet low temperature Plasma plasma cleaning machine. At present, the outlet temperature (instant temperature) of the spray gun researched by Chengfeng Zhizhi is only 50-80 degrees, and it has begun to be promoted and applied in the home appliance and automobile industries. In industry, such as argon arc welding, air plasma cutting and plasma spraying, plasma plasma cleaner low temperature plasma has been widely used. The core component of this type of device is usually called a plasma torch. Its plasma center temperature is as high as several thousand degrees, which is a thermal plasma. In recent years, in order to improve the adhesion performance to organic materials, such as rubber surface treatment, the plasma torch process has been lowered and miniaturized, and the hot arc has been transformed into a cold arc, and a low-temperature plasma jet plasma cleaning machine has been developed. 1. Atmospheric jet low-temperature plasma surface treatment principle: The air flow of the cold arc plasma jet gun can produce oxygen-based active substances containing a large number of oxygen atoms. These oxygen atoms process the surface of the material and can be separated and attached to the surface of the material. The organic pollutant C, which is converted into carbon dioxide, is removed; at the same time, it can improve the contact performance, thereby increasing the strength and reliability of the connection. Industrial application of low-temperature plasma activation technology in the atmosphere. (a) Pre-welding treatment Stainless steel sheet butt welding is widely used in industry. For example, the inner barrel of a solar water heater is made of 0.4mm stainless steel sheet rolled into a cylindrical shape and welded. In order to meet the welding requirements, the welding part must be cleaned. The current cleaning method is a wet method, which uses a chemical cleaning agent to manually scrub. The cleaning cost is high, the pollution is large, and it is difficult to realize automation. Atmospheric jet low-temperature plasma cleaning activation technology is a dry cleaning technology, applied to the pre-treatment of butt welding of thin plates, which can replace traditional manual chemical cleaning agents, reduce cleaning costs, improve welding quality, and reduce environmental pollution. Automation of welding area cleaning. (B) Surface treatment of plastic sheets, such as wood plastic, is a new type of material that can replace wood, but surface coating is very difficult, which greatly limits its scope of application. If chemical treatment is used, the cost is high and the pollution is large. Therefore, with low temperature plasma cleaning machine, the surface of the material will have obvious changes: the color is slightly lighter, the reflectance is reduced, and the surface is in a matte state; the surface is slightly rough when touched by hand; the adhesion performance of the spray paint is greatly improved . The bonding force before and after plasma treatment can be tested. Test method: Use a scraper to make a scratch on the surface of the part to be tested, and use a soft brush to scrape off the debris on the surface. Use scotch tape to stick the line on the line. There should be no air bubbles between the tape and the sample. Keep it for 1 to 2 minutes, and tear off the tape at a constant speed of 60 degrees. Judge the bond strength by observing the integrity of the scribe line and the square. In our daily life, such as door seals on cars, we often use rubber-processed products. The surface should be painted or woven. If there is no low-temperature plasma treatment, adhesion is not easy. If chemical cleaning is used, it will be offline and pollute the environment. The ideal solution is to use online plasma treatment. (C) The air plasma jet used for glass and metal plates can treat glass and metal surfaces, which can not only effectively remove organic pollutants from floating dust in the atmosphere, but also change the surface performance to make it last long enough. Thereby improving the joint strength of the product. In addition, atmospheric pressure plasma cleaning can be applied to the surface of organic and metal materials.

Application effect of wide-format plasma equipment: 1. Improve the surface adhesion ability and improve the reliability and durability of surface adhesion. 2. After the atmospheric pressure plasma treatment is used, the surface energy of materials such as various polymer plastics, ceramics, glass or metals have been improved. 3. Through such a treatment process, the surface tension performance of the product is improved, and it is more suitable for processing requirements such as coating and bonding in the industry. 4.

The wide-format plasma equipment technology has the following characteristics: 1. The wide-width plasma equipment can process materials with a width of 1-3 meters, which can meet the surface treatment requirements of most existing industrial materials. 2. High uniformity: The atmospheric pressure plasma is a glow-type plasma screen, which directly acts on the surface of the material. Experiments have shown that the same material can be processed at different positions with high uniformity. This feature is important for the continuous casting, Processes such as coating and printing are of great significance. 3. Low cost: The gas pressure plasma equipment has low energy consumption, and the operating cost is mainly gas.

No vacuum chamber, no arc, no harmful gas suction system, long-term use will not cause harm to the operator's body. 5. The effect is controlled: There are three effect modes for the large-width plasma equipment plasma to choose from. First, the choice of argon/oxygen combination is mainly for non-metallic materials, and has higher requirements for treatment effects. Secondly, choose the combination of argon/nitrogen, mainly for areas where there are unprocessable metals in the product to be processed. In this solution, due to the strong oxidation of oxygen, the problem can be controlled after replacing nitrogen. Thirdly, using only argon gas, the surface modification can also be achieved using only argon gas, but the effect is relatively low. This situation is rather special, and it is a scheme adopted by some industrial users when they need to perform uniform surface modification at the same time.

After the IP glue is processed by the plasma cleaner, its contact angle to DIW is extremely significantly reduced

After the IP glue is processed by the plasma cleaner, its contact angle to DIW is extremely significantly reduced: IP glue is a kind of photoresist widely used in 0.25μm photomask design rules and below. IP3600 is a photoresist commonly used for 0.25DR Hline photomasks. Even in the secondary mask processing of the 130nm process phase shift mask technology, IP glue is still used. IP glue is a kind of photoresist based on phenolic resin. The main difference between it and poly-type glue is that the surface of the glue has obvious anti-decomposition phenomenon, that is, it has poor hydrophilicity. For IP glue, its poor hydrophilicity will make it difficult for the developer to evenly act on the glue surface during development, resulting in defects or incomplete development. Therefore, in the development of IP glue, one of the technological difficulties is how to improve the hydrophilicity of the IP glue before development. Plasma cleaner is a pre-cleaning method commonly used in semiconductor manufacturing and packaging. Plasma pretreatment (bombardment) can physically remove some pollution on the surface of silicon wafers or chips (such as natural oxide layers, ash particles, and organic pollutants). Wait). The plasma surface pretreatment method is used to act on the surface of the IP glue to increase the roughness of the glue surface, thereby improving the uniformity of the deionized water wetting the glue surface, and avoiding the development defects caused by the hydrophilicity of the IP glue. During the surface treatment of the plasma cleaner, the thickness of the IP glue will be lost due to the bombardment of the plasma. In order to facilitate the control of subsequent development time and development uniformity, the thickness loss of the IP glue caused by plasma bombardment must be considered. After the surface treatment of the reticle by the plasma cleaning machine, due to the loss of plasma bombardment, the thickness of the IP glue decreased from 564.4nm before the treatment to 561.2nm after the treatment, and the thickness loss was about 3.2nm, which is far before the thickness of the IP glue before development. The deviation can be controlled within (565 +10) nm. This shows that although the surface bombardment effect will cause a certain loss of the thickness of the IP glue, the plasma energy for the treatment is lower and the time is shorter, so the thickness loss caused by it is smaller. . On the whole, this plasma surface treatment will not have a significant impact on the thickness of the IP glue. After the IP glue is processed by the plasma cleaning machine, its contact angle to DIW is extremely significantly reduced, that is, the static contact angle is reduced to 45° from the untreated 77°, and the forward contact angle is reduced to 51° from the untreated 88°. It also reduces the receding contact angle from the untreated 33° to less than 10°. This shows that due to the bombardment of the surface of the IP glue by plasma, the micro-roughness of the surface is increased, thereby increasing the adsorption and wetting ability of the IP glue to water, and improving the hydrophilicity of the surface of the IP glue. In the water rinsing step before development, it is obvious that the surface water drops on the plasma-treated reticle become smaller and are densely and uniformly distributed on the surface of the glue, which also shows its hydrophilicity and development The uniformity has been significantly improved.
