Plasma surface treatment can improve the hydrophilic bonding ability of steel /EPDM surface

Plasma surface modification technology is a kind of gas-solid coherent reaction system, which can effectively improve the hydrophilic, hydrophobic and biocompatibility of metal surface and greatly improve the bonding fastness of metal-metal and metal-polymer without introducing other substances and causing environmental pollution. Cleaning the metal surface is the preparation process and prerequisite for the production of various metal products. Proper cleaning methods and high quality cleaning techniques can improve the quality and performance of metal products. Among them, plasma surface treatment technology is a cleaning technology developed in recent years, and it is also one of the research hotspots in the field of atmospheric pressure plasma jet application at home and abroad. Compared with the traditional cleaning technology, plasma surface treatment has the advantages of high efficiency, environmental protection and no pollution, and compared with other cleaning technologies, plasma surface treatment has the advantages of rapid, simple, economical and controllable. The material of solid state engine combustion chamber shell is mainly steel, which is generally treated with sand blasting and solvent cleaning, followed by an insulating layer, which plays a heat preservation and heat protection role on the combustion chamber shell, prevents the high temperature and high pressure gas from reducing the strength of the shell, impairing the structural integrity of the shell, and ensures the reliable operation of the engine. EPDM rubber has the advantages of low density, good weather resistance, good aging resistance, high thermal insulation performance, corrosion resistance and so on. It is widely used in aerospace and other fields, especially for the insulation layer in the combustion chamber of solid rocket motor. EPDM as the engine of the solid insulation insulation materials, at present, the domestic research has made great progress, but the main chain of the EPDM rubber molecular structure of the saturated, itself is weak polar material, low surface energy, contact Angle, adhesive infiltration is difficult, weak boundary layer and caking difficulties, low bond strength, this limits the application of EPDM in a wider field. In the pre-treatment process, EPDM sealants are sprayed with a lubricant coating or flocking glue, replacing mechanical grinding and chemical undercoating, making them environmentally friendly. The sealing strip is pretreated with plasma surface treatment technology to make it more stable, efficient and free from wear and tear. Plasma surface treatment can improve the hydrophilicity of high steel surface, mainly by cleaning the material surface, while the hydrophilic effect is affected by the treatment power, time, distance and times, and the magnitude of which is in turn power, distance, time and times. The shear strength corresponds to the surface energy of steel. Similarly, under the same conditions, increasing the surface energy is beneficial to improving the bonding performance.

How plasma surface treatment works-CRF PLASMA

How plasma surface treatment works-CRF PLASMA

A plasma is a collection of electrically neutral substances composed of ions, electrons and neutral particles. During plasma surface treatment, the plasma transmits its energy to the molecules and atoms on the surface of the material when it collides with the surface of the material, resulting in a series of physical and chemical reactions. By injecting particles or gases into the surface of the material, it can cause collision, scattering, excitation, rearrangement, isomerization, defect, crystallization and amorphous, so as to change the surface properties of the material. 1. Etching effect of plasma surface treatment on material surface: Under physical action, a large number of ions, excited molecules, free radicals and other active particles in the plasma will act on the surface of solid samples, which can remove the original pollutants and impurities on the surface. This process also produces etching, which can make the surface of the sample rough, forming many tiny pits, increasing the roughness ratio of the sample surface, and improving the adhesion and wetting properties of the solid surface. 2. Effects of plasma surface treatment on activation bond energy and cross-linking: The particle energy in the plasma is between 0 and 20eV, while most of the bond energy in the polymer is between 0 and 10eV. Therefore, after plasma surface treatment ACTS on the solid surface, the original chemical bonds on the solid surface can be broken, creating a new reaction atmosphere. Free radicals in the plasma can form a network crosslinking structure with these bonds, which greatly activates the surface activity. 3. Plasma surface treatment can form new functional groups: When plasma surface treatment is carried out, introducing reactive gas into discharge gas will produce complex chemical reactions on the surface of activated material. In this process, new functional groups can be introduced into the material surface, such as hydrocarbon group, amino group, carboxyl group, etc. These new functional groups are some active groups, which can significantly improve the activity of the material surface. The principle of plasma surface treatment is mainly to use the active particles in the plasma for "activation", so as to achieve the treatment effect of removing the pollutants on the material surface. Plasma surface treatment usually involves the following reaction processes: (1) Firstly, the inorganic gas is excited into a plasma state; (2) The gaseous phase substances are adsorbed on the solid surface through the action; (3) The adsorbed substances react with molecules on the solid surface to form product molecules; (4) The product molecules are then analyzed to form the gas phase, so as to achieve the effect of the reaction residue off the surface.

Plasma cleaning machine principle and cleaning advantages

Plasma cleaning machine principle and cleaning advantages

Plasma cleaning machine cleaning principle: The plasma cleaning machine USES gas as the cleaning medium, which can effectively avoid the secondary pollution caused by liquid cleaning. A vacuum pump is attached to the plasma cleaning machine, and the plasma in the plasma cleaning chamber constantly washes the material surface during the operation. After a short time of cleaning, the organic pollutants can be effectively cleaned off, and then the pollutants can be removed by the vacuum pump, and the cleaning degree can reach the molecular level. In addition to the super cleaning function, the plasma cleaning machine can also change the surface performance of some materials according to the needs under certain conditions. The plasma ACTS on the surface of the material and changes the chemical bonds of the molecules on the surface of the material so that new surface properties can be formed. For some materials with special purpose, the glow discharge of the plasma cleaning machine not only enhances the adhesion, compatibility and infiltration of these materials, but also can achieve disinfection and sterilization. Plasma cleaning machine is widely used in the fields of optics, optoelectronics, electronics, material science, life science, polymer science, biomedicine, microfluidics and so on. Advantages of plasma Cleaning Machine (compared with traditional process): 1. Able to adopt precise numerical control technology with high degree of cleaning automation; With high precision control device, high precision of time control; Correct plasma cleaning will not produce damage layer on the surface of the product surface quality can be guaranteed; The cleaning process is carried out in a vacuum environment, which is an environmentally friendly cleaning process that does not pollute the environment, and effectively avoids the influence of human factors. The cleaning surface will not be contaminated by secondary pollution. 2. Many materials should be cleaned to change their surface tension and improve their adhesion before they need to be bonded. Plasma material and surface organic pollutants have chemical reaction, the waste gas is extracted by the vacuum pump, so as to achieve the purpose of cleaning the surface of the material. The test results show that the surface tension changes significantly before and after cleaning, which is helpful for the next bonding process. Surface modification of the material before surface spraying can improve the spraying effect of the material. Some chemical materials, such as PP or other chemical materials, are hydrophobic or hydrophilic, but they can also be cleaned by plasma through the above process, modify the surface of the material, so that its hydrophilic or hydrophobic to improve, facilitate the next spraying process. 3, the plasma cleaning machine has online production capacity, and can achieve full automation. Plasma cleaning is a very environmentally friendly process. It is not limited by geometric shape, and can be used for surface treatment of powder, small parts, sheet, non-woven cloth, textiles, hoses, hollow bodies, printed circuit boards, etc. It is a nondestructive process without any mechanical changes to the parts. Besides, it meets the harsh conditions such as clean room, easy to use, flexible and simple to operate, and has remarkable treatment effect for various parts and components. The process conditions are controllable, and the cost is low, the effect is good, and the time is short. The appearance of the treated products will not be affected by the high and low temperature of plasma treatment, and the parts will be less heated. The plasma cleaning machine has the advantages of low operation cost, high process safety and operation safety, and is also a cleaning process with remarkable effect after treatment.

What causes the smell of plasma cleaning machines

What causes the smell of plasma cleaning machines

The answer is that ozone is at work. The basic principle of ozone generation during plasma discharge is that oxygen molecules are decomposed into oxygen atoms in the low-temperature plasma gas formed in the discharge reactor, and then ozone molecules are formed through the three-body collision reaction, which also takes place in the ozone decomposition reaction. Ozone, chemical molecular formula for O3, also known as triatomic oxygen and superoxygen, because of its fishy taste and named, room temperature can be reduced to oxygen. Compared with oxygen, it is soluble in water and easily decomposed. Ozone consists of an oxygen atom carried by an oxygen molecule, which determines that it is only temporarily stored. The oxygen atoms that carry them are used up by oxidation, and the rest combine to form oxygen into a stable state, so there is no secondary pollution of ozone. If the gas we introduce contains oxygen, a small amount of ozone will be produced during the reaction. It is because of the production of ozone, we can sometimes smell a bad smell when using the plasma cleaning machine, which is also the reason that the plasma cleaning will produce a bad smell. Plasma cleaning machine, also known as plasma surface treatment instrument, is a new high-tech technology, the use of plasma to achieve conventional cleaning methods can not achieve the effect. Plasma is a state of matter, also known as the fourth state of matter, does not belong to the common solid liquid gas three states. By applying enough energy to a gas, it can be ionized into a plasma state. The "active" components of plasma include ions, electrons, atoms, active groups, excited nuclides and photons, etc. The plasma cleaning machine USES the properties of these active components to treat the sample surface, so as to achieve the purpose of cleaning. Conditions for plasma production: sufficient reaction gas and pressure, reaction products must be able to hit the surface of the cleaning object at high speed, and sufficient energy supply. The resulting substances must be volatile micromixtures so that they can be pumped away by vacuum pumps. The capacity and speed of the pump must be large enough to rapidly remove the by-products of the reaction and to replenish the gas required for the reaction.

Nitrogen plasma cleaning machine Manufacturer

According to the nature of gases, plasmas can be divided into the following two types: Gas and the gas plasma: gaseous plasma according to their chemical properties of the gas used when different can be divided into two categories, lively and inert gas gas, inert plasma such as argon (Ar), nitrogen (N2), nitrogen fluoride (NF3) is used, carbon tetrafluoride (CF4), air, gas plasma such as oxygen (O2), hydrogen (H2), etc., the reaction mechanism of different kinds of gas in the process of cleaning, lively plasma have bigger influence on the chemical reaction. Because of the different nature of gases, the pollutants used for cleaning them must also have different choices. If one gas permeates into another or more gases, the mixture of these elements will produce the etching and cleaning effects we want. By using the ions or highly active atoms in plasma, the surface pollutants are smashed apart or formed into volatile gases, which are sent out through the vacuum system to achieve the purpose of surface cleaning. At low pressure in a high-frequency electric field, gas molecules, such as oxygen, nitrogen, methane, water vapor, in a glow discharge, will break down the accelerating atoms and molecules. When the generated electrons are accelerated in the electric field, they can obtain high energy and collide with the surrounding molecules or atoms, so that the molecules and atoms are reexcited by the electrons, but they are in the excited state or ionic state. At this time, the existence state of the matter is the plasma state. In addition to gas molecules, ions and electrons, there are electrically neutral atoms or groups of atoms in a plasma, which are excited by the state of energy (also known as free radicals) and the light emitted by the plasma. Among them, the length and energy of the wave play an important role in the interaction between the plasma and the material surface. In the plasma cleaning process, nitrogen as an inactive gas, mainly as a non-reactive gas, nitrogen plasma treatment can improve the hardness and wear resistance of materials. Sometimes, nitrogen also ACTS as an active gas, forming ammonia compounds. In many cases, plasma cleaner manufacturers use nitrogen or use it as an inactive gas.
