The advantages of vacuum plasma cleaning machine

The advantages of vacuum plasma cleaning machine

The plasma cleaning process can get effective vacuum cleaning. In contrast to plasma cleaning, water washing is usually a dilution process. Compared with CO2 cleaning technology, plasma cleaning does not need to use other materials. Compared with sandblast cleaning, plasma cleaning can optimize the surface structure of the material, not just the surface protrusion. It can be integrated online with no extra space. Low operating cost, environmentally friendly pretreatment process.

Theoretical analysis of cleaning machine of plasma surface processor

Theoretical analysis of cleaning machine of plasma surface processor

Let's first simply define what plasma is. A plasma is a glowing gas mass composed of positive ions, electrons, free radicals and neutral gas atoms. For example, a fluorescent lamp or a neon red light shines in the state of plasma shining. Plasma is mainly produced by the electronic gas atoms to the crash, the neutral gas atoms disintegrate and plasma, but of gas nucleus on the periphery of electronics has a binding energy, we call it the binding energy, the electronic energy must be greater than the binding energy of the outside world, will have the ability to solve from the neutral gas atoms, but the external electronic is often insufficient energy, no dissociative gas atoms in ability, so we have to use to the energy of electrons in an atom on the method of energy, make the electronic has use disintegrate the neutral gas atoms. Plus energy to electronic, its method is to use parallel plate electrode has been flow voltage, electron in the electrode, will be attracted by positively charged electrode and accelerating, in the process of accelerating electrons can accumulate energy, when the energy of an electron reaches a certain extent, have the ability to ionize the gas atoms, the methods which can produce high density plasma has a lot of kinds, we simply introduce some methods to produce high density plasma, plasma surface treatment machine is modified according to the design.

Common problems with plasma surface treatment equipment

Common problems with plasma surface treatment equipment

1. Processing time of plasma surface treatment equipment? The chemical modification on the polymer surface of plasma equipment is due to free radicals. The longer the plasma equipment is processed, the greater the discharge power will be. Therefore, it needs a good grasp. 2. What is the power of the plasma surface processor? The power of a common plasma device is about a thousand watts. 3. How long can I keep the products with the surface treatment of plasma processor? This is based on the material of the product itself. In order to avoid secondary pollution of the product, it is suggested that the next process can be carried out after the plasma surface treatment, which can effectively solve the problem of secondary pollution and improve the performance and quality of the product. 4. Will the plasma device produce harmful substances during use? There is no need to worry about this problem, because the plasma equipment has a full set of preventive measures when it is processed. It will be equipped with an exhaust system, and a small part of ozone will be ionized by the air, so it is not harmful to human body. The above problems are some common problems of plasma surface treatment equipment, so the manufacturers who buy and use plasma surface treatment equipment can rest assured to use, because it will not produce harmful substances in the process of treatment, it is this characteristic that the plasma equipment has achieved good results in the market.

Plasma grafting

Plasma grafting

When the group generated by plasma surface activation or plasma-initiated polymerization layer cannot be firmly bonded to the material surface, plasma grafting is often used to improve it. The principle of plasma grafting is as follows: first, the surface activation is used to generate new active groups on the surface of the material, and this group is used to generate chemical covalent bonds with the following active substances, which contain specific groups that can meet the application requirements, so as to achieve the purpose of meeting both surface characteristics and firm binding. In plasma surface modification of materials, surface grafting by plasma surface processor (PSMP), due to the effect of active particles on surface molecules, the surface molecular chain is fractured to generate new active groups such as free radicals and double bonds, and then surface crosslinking and grafting reactions occur.

What is plasma

What is plasma

Plasma is an ionized gaseous substance composed of atoms deprived of some electrons and positive and negative ions generated after ionization of atomic groups. It is a macroscopic electroneutral ionized gas with a scale larger than Debby's length. Its motion is mainly controlled by electromagnetic force and shows significant collective behavior. It is widespread in the universe and is often seen as the fourth state in which matter exists apart from solid, liquid and gas. Plasma is a good conductor of electricity, and it can be captured, moved, and accelerated using a clever magnetic field. The development of plasma physics provides new technologies and processes for the further development of materials, energy, information, environmental space, space physics, geophysics and other sciences. A plasma is a fourth state of matter different from solids, liquids and gases. Matter is made up of molecules, which are made up of atoms, which are made up of a positively charged nucleus and the negatively charged electrons surrounding it. When heated to a high enough temperature or for other reasons, the outer electrons break free from the nucleus and become free electrons, just like a student running to the playground after class. The electrons leave the nucleus, a process called ionization. At this time, the matter will become a positive nucleus and negative electrons composed of a uniform "paste", so people jokingly called it plasma, plasma, the total amount of positive and negative charges in the plasma is equal, so it is approximately neutral, so called plasma. The seemingly "mysterious" plasma is actually a common material in the universe. It is found in the sun, stars and lightning, and accounts for 99 percent of the entire universe. In the 21st century, people have mastered and used electric and magnetic field generation to control plasma. Common plasma is high temperature ionized gas, such as arc, neon lights and fluorescent lights in the gas, such as lightning, aurora, etc. The electron gas in the metal and the carrier in the semiconductor and the electrolyte solution can also be regarded as plasma. On earth, there are far fewer plasma materials than solid, liquid, or gaseous materials. In the universe, plasma is the main form of matter existence, accounting for more than 99% of the total matter in the universe, such as stars (including the sun), interstellar matter and the ionosphere around the Earth, etc., are plasma. In order to study the generation and properties of plasma to clarify the movement law of plasma in nature and use it for human service, magnetohydrodynamic and plasma dynamics have been formed in the past 30 or 40 years under the impetus of astrophysics, space physics, especially nuclear fusion research. Plasma is composed of a collection of ions, electrons and unionized neutral particles in a neutral state of matter. Plasmas can be divided into two types: high temperature and low temperature plasmas. Plasma temperature is respectively expressed by electron temperature and ion temperature, which are equal to each other and called high-temperature plasma. The difference is called a low temperature plasma. Low temperature plasma is widely used in many kinds Production area. For example: plasma TV, baby diaper surface waterproof coating, increase beer bottle barrier. What is more important is the instant application of computer chips to make the Internet era a reality. High-temperature plasmas occur only when the temperature is high enough. Stars constantly emit this plasma, which makes up 99% of the universe. A cryogenic plasma is a plasma that occurs at room temperature (although electrons are very hot). Low temperature plasma can be used for surface treatment such as oxidation, denaturation, or precipitation coating on organic and inorganic materials. Plasma is a form of matter composed mainly of free electrons and charged ions. It is widely found in the universe and is often regarded as the fourth state of matter. It is called Plasma state, or "supergas", or "Plasma". Plasma has high conductivity and strong coupling effect with electromagnetic field. Plasma was discovered by Crooks in 1879, and in 1928 the American scientists Irving Langmuir and Tonks first introduced the term 'plasma' to physics to describe the form of matter in gas discharge tubes [1]. Strictly speaking, a plasma is a gas cluster with high energy and kinetic energy. The total charge of the plasma is still neutral. By high energy of electric field or magnetic field, the electrons in the outer layer are shot out. A plasma is the fourth state of matter, an ionized "gas," which exhibits a highly excited unstable state consisting of ions (with different symbols and charges), electrons, atoms and molecules. In fact, the plasma phenomenon is not new. In nature, hot flames, brilliant lightning, and brilliant auroras are all the result of plasma action. For the universe as a whole, more than 99.9% of matter e

Plasma cleaning

Plasma cleaning

In the process of industrial production, super-purity cleaning of electronic components, optical components, mechanical parts, polymer materials and other surfaces to remove extremely small dirt particles is often a very critical process. Most of the traditional cleaning methods are wet cleaning. With the continuous development of modern high technology, this cleaning method has exposed many defects, that is, the residual cleaning agent and tiny particles will adhere to the surface after cleaning and drying, which cannot meet the requirements of modern high technology. The low-temperature plasma cleaning process actually removes the pollutants from the treated workpiece and takes them away under the impact of plasma reaction. Generally, the treatment cycle only takes a few minutes to remove the surface smudge-free and zero pollution. Because gas penetrates far more into tiny crevices than liquid, complex objects can also be thoroughly cleaned. The decisive factor in the plasma cleaning process is that no matter in the atmospheric pressure state or vacuum state, even under the greenhouse conditions, the plasma will react with organic pollutants, decompose into molecules such as water and carbon dioxide, and have good volatilization. Advantages of plasma cleaning: The treatment temperature is low and has wide suitability. Clean thoroughly without residue. Process control, good consistency, support downstream drying process. Low cost of use and waste disposal. Environmental protection technology, no harm to the operator's body. Plasma application Industry: Science software, semiconductor, microelectronics, printed circuit board, precision machinery, medical polymer, hardware processing, clock manufacturing, optical fiber cable, photovoltaic new energy, glassware.
