Domestic plasma cleaning machine wholesale machinery production technology to improve the ability of environmental protection

Facing the current serious global economic pressure, and high Labour costs, in order to solve the development of the enterprise in the new environment, the industry is generally believed that should change the original production mode, adopting efficient domestic wholesale plasma cleaning machine equipment to replace the low efficiency of manual mode of production, so that the domestic plasma cleaning machine better play its role in the new environment, green environmental protection so as to win the favor of the market better. The use of non-standard automation domestic plasma cleaning machine machinery for product production and processing, not only can effectively improve the degree of standardization of products, but also can greatly improve the production efficiency of enterprises, reduce production costs. In the production of the use of domestic plasma cleaning machine equipment, to a large extent to help enterprises to solve the shortage of labor, difficult to recruit workers and other problems. If the production of the same number of products, if the use of manual processing, may need ten people, and the use of automatic plasma cleaning machine production technology, only two people about the control equipment can be, while the processing of products than manual processing standardization is much, and the use of short time. The unique domestic plasma cleaning machine wholesale machinery production has so many advantages, why not in the production of vigorously promote the application? The main factors affecting the popularization of plasma cleaning machine are the lack of understanding of domestic plasma cleaning machine and the lack of production technology of plasma surface treatment machine. At present, it is difficult to realize the production of domestic plasma cleaning machine with real high efficiency. Therefore, many enterprises are worried about the production of equipment, worried that they spent a lot of money to buy a plasma cleaning machine, still can not improve the production efficiency, but increased the cost of equipment maintenance. The customer's concern is right, to solve these problems, but also need our professional plasma cleaning machine wholesale manufacturers continue to improve the technical level, produce higher quality products, provide better services, to help customers solve their worries.

Oxidation resistance of plasma sprayed thermal barrier coatings

Oxidation resistance of plasma sprayed thermal barrier coatings

With the development of aviation industry, the inlet temperature and efficiency of turbine engine gas are constantly improving, but the existing superalloy and cooling technology can not meet this demand. Therefore, the application of plasma sprayed thermal barrier coating on the surface of superalloy is particularly important, and thermal barrier coating has a long history of working at high temperature. Antioxidant capacity is an important index to evaluate the properties of plasma sprayed thermal barrier coatings. The thermodynamic and kinetic analysis of high temperature oxidation behavior of plasma sprayed thermal barrier coatings was carried out by using the method of weighing and oxide layer thickness. The composition distribution and structure changes of the samples were studied by means of X-ray diffraction and electron probe. The oxidation mechanism of thermal barrier coating was discussed based on the experimental results. The static oxidation performance of ZrO2 thermal barrier coating prepared by atmospheric plasma machine spraying was tested by using MgO and Y2O3 as stabilizers. It was found that the static oxidation kinetics of the two thermal barrier coatings followed a parabolic rule, and the porosity decreased with the increase of oxidation temperature, while the monocline content increased. Although the MgO content is higher than that of Y2O3, the Y2O3-stabilized ZrO2 thermal barrier coating has better thermal stability. However, in the Y2O3 stabilized ZrO2 thermal barrier coating, Al element is uniformly distributed on the transition layer and has good oxidation resistance. The Y2O3-ZrO2/NiCoCrAlY composite thermal barrier coating was prepared by low pressure plasma spraying technology, and the static oxidation test was carried out at 800-1000℃. The thermal barrier coating has good high temperature oxidation resistance by spraying the adhesive layer by low pressure plasma processor. Moreover, after the sample is oxidized for a long time at a high temperature, the aluminum element in the binder layer will diffuse to the interface between the ceramic layer and the binder layer, forming a uniform and dense double alumina film, which can protect the matrix more effectively. Research on three kinds of high temperature oxidation behavior of thermal barrier coating showed that plasma oxidation process of thermal barrier coating can be divided into oxygen absorption, diffusion of oxygen in the ceramic layer, selective oxidation Al2O3 film, film growth, thick film and thick film destroyed six stages, including the distribution of aluminum directly affect the growth of the protective film and mature, will affect the oxidation resistance of the coating.

Plasma surface treatment of polymer materials surface applications

Plasma surface treatment of polymer materials surface applications

Most organic gases are polymerized and deposited on the solid surface under the action of low-temperature plasma surface treatment to form continuous, uniform, pinhole-free ultrathin films, which can be used as protective materials, heat insulation materials, liquid-gas separation films and laser guided films, etc., and are widely used in optical, electronic, medical and other fields. Poly (methyl methacrylate) or polycarbonate plastic plasma polymer can be used to produce inexpensive, high-quality and easy to process optical lenses, but the surface hardness of the lens is too low, easy to produce scratches. Plasma deposition with fluorine or silicone monomer on the surface of the lens at low temperature can improve the anti-scratch performance and reflectivity of the lens. Plasma chemical vapor deposition technology has been applied to plastic window glass, automobile blinds, car lights and halogen sky lamps. Plasma polymer films have many properties that allow the same substrate to be used in many fields. The method of chemical vapor deposition for diamond carbon wear resistant coating is to introduce carbon gas into plasma. This plasma has the characteristics of chemical resistance, no pinhole, no leakage and so on, which can prevent various chemical agents from corroding the substrate. You can also apply antifriction paint to windshield wipers or a low friction paint to computer disks to reduce head collisions. Plasma polyethylene film deposited on the surface of silicone rubber can significantly reduce the oxygen transmission coefficient of silicone rubber. The reverse osmosis membrane was prepared with nitrogen-containing monomer, and the salt resistance of the membrane reached 98%. In general, polymer microcapsules are used for biological sustained-release drugs. Reverse osmosis film can be formed on the surface of microcapsules by plasma polymerization technology. The results show that the discharge power and other factors have a great influence on the resistance of plasma polymer films when they are used as sensor elements. After treated with different vinyl monomers and AR glow discharge, the hydrophobicity and dyeing properties of the fabric were improved in a very short time.

The difference between different frequency excitation plasma of plasma processor

The difference between different frequency excitation plasma of plasma processor

The density and excitation frequency of plasma are as follows: Nc = 1.2425 x 108 v2 Where, Nc is plasma density (cm-3) and V is excitation frequency (Hz). There are three common excitation frequencies of plasma: ultrasonic plasma excitation frequency is 40kHz, RF plasma processor plasma excitation frequency is 13.56MHz, microwave plasma excitation frequency is 2.45GHz. Various plasmas produce different self-bias voltages. The self-bias voltage of ultrasonic plasma is about 1000V, that of RF plasma processor is about 250V, and that of microwave plasma is very low, only dozens of volts. Moreover, the three kinds of plasma have different mechanisms of action. The reaction of ultrasonic plasma is physical reaction, the reaction of radio frequency plasma processor plasma is physical and chemical reaction, the reaction of microwave plasma is chemical reaction. Because of the great influence of ultrasonic plasma on the surface to be cleaned, RF plasma cleaning and microwave plasma cleaning are mostly used in the actual production of semiconductor cleaning activation bonding.
