Plasma can be divided into two types: high temperature plasma and
low temperature plasma
. Nowadays, low temperature plasma is widely used in various production fields. Liquid crystals (LC) are a polymer material. Due to their special physical, chemical and optical properties, they have been widely used in thin and light display technology since the mid-20th century. Nowadays, various flat screen TVs have started to be. emerging, and many families After eliminating the old CRT TVs, they all focused on these brand new products. However, what bothers many ordinary consumers is that flat panel TVs are divided into two types: LCD TVs and plasma TVs. They look basically the same, but their prices are quite different. The seller for a long time and I couldn't understandclearly. This time the editor will give you a literacy lesson. If you have any questions about this, you can find out the differences between the two and their respective advantages and disadvantages in this article. Let's start with... Plasma is abbreviated as PDP in English, and it is called "plasma" in Taiwan. The English abbreviation for plasma display is PDP TV. First, let’s talk about what plasma means. We know that
Forms of matter include solid, liquid and gas. For example, water is solid below freezing and is ice. Put it in a pan and burn it. When the temperature increases, the ice turns into liquid and becomes water. If you burn it harder, when it reaches boiling point, the water will turn into a gaseous state, called water vapor.
What would happen if the vapor of water was heated, for example, to several thousand or tens of thousands of degrees? Thisst the fourth state of matter, the plasma state! Don't think plasma is mysterious. In fact, 99% of the matter in the universe we live in is in the plasma state. It should be noted that plasma does not have to be "hot" and some temperatures are not very high. #Common neon lights are also a kind of light-emitting device that uses the plasma state: a sealed glass tube with electrodes on both ends is filled with certain rare gases such as nitrogen, neon and others gas. Once the rare gas is ionized, it is used. will emit light of a specific color. The gas is different, the color of the light is also different. The plasma display unit is composed of two front and rear glass substrates. There are transparent ITO electrodes on the front panel glass and a bus electrode which improves the conductivity of the ITO. The electrodes are covered with a layertransparent dielectric and a protective layer of magnesium oxide. , mainly to protect the electrodes from losses caused by discharge shock. There are data electrodes, dielectric layers and strip-shaped interlayers on the rear panel glass, and three red, green and blue fluorescent materials are printed in each interlayer. A thin gas mixture is evacuated between the upper and lower substrates and then encapsulated. LG 102-inch Plasma TV
When the electrodes are energized, electrons flow between the two electrodes to form a current, forming an electric field that excites the inert gas into a plasma state. The inertia of the plasma state. The collision of gas and electrons produces ultraviolet light, which causes red, green, and blue phosphors to emit light, producing the corresponding colors. A plasma television is therefore in fhas a very precise neon!
The difference between plasma water and demineralized water
Machine plasma and manual plasmaThe difference between them:
The method Mechanical plasma arc starting method is non-contact arc starting
The manual plasma arc starting method is contact arc starting
In simple terms, manual plasma cutting is carried out next to the steel plate, while CNC plasma cutting is not carried out next to the steel plate.
If the same plasma power supply supports non-contact arc starting, the difference between the two cutting methods is the cutting capacity. The thickness of manual cutting is larger than that of CNC cutting.
The water spray device is used on some specific plasma cutting machines. It is mainly used in thin plate cutting industry. The plasma cutting temperature is relatively high to prevent the plaque from being affected. by temperature during processing of thin plates. Turns black and affects the cutting effect. Also, the water does not come from the trachea: there should be a special pipe connected to the tap. If the material you are cutting is relatively thick or carbon steel and you are concerned about the plate rusting, you can turn off the water. It will not have a big impact on the actual cutting effect.

Inconsistent definitions and different uses.
1. Inconsistent definitions: Plasma water is carbonated water. Deionized water refers to pure water after removing impurities in ionic form.
2. Different uses: plasmati waterque is mainly used in cosmetics and skin care products, and its main function is as a solvent. Deionized water is used for chemical laboratory water needs.
Plasma, also called plasma, is an ionized gas-like substance composed of positive and negative ions produced by ionization of atoms and atomic groups after some electrons have been deprived of them . that Debye The movement of a macroscopically neutral ionized gas of a certain length is mainly governed by the electromagnetic force and exhibits significant collective behavior.
It exists widely in the universe and is often considered the fourth state of matter after solid, liquid and gas. Plasma is a good conductor of electricity and cleverly designed magnetic fields can be used to capture, move and accelerate plasma.
The development of plasma physics foprovides new technologies and processes for the further development of materials, energy, information, environmental space, space physics, geophysics and other sciences.
Detailed information:
Plasma is a substance different from solids, liquids and gases. fourth estate. Matter is made up of molecules made up of atoms made up of a positively charged nucleus surrounded by negatively charged electrons.
When heated to a high enough temperature or for other reasons, outer electrons escape from the chains of the atomic nucleus and become free electrons, just like students running to the playground. recess after school to play casually. When electrons leave the nucleus, this process is called "ionization."
At this time, matter consists of positively charged atomsment.A uniform “sludge” composed of daughter nuclei and negatively charged electrons, which is why people jokingly call it ion sludge. The total amount of positive and negative charges in this ion slurry is equal, so it is approximately electrically neutral, which is why it is called plasma.
