Description

A stick for the electrostatic induction

The present invention relates to a "round rod for electrostatic induction" for facilitating the generation of static electricity, more specifically, characterized in that the main component is composed of 'Crystalline Carbon, sodium polyacrylate, zirconium oxide' do. This is a technology related to a new electrostatic induction equipment to induce static electricity in a short time to facilitate dust and foreign matter dust collection.

The present invention relates to a mixture for generating static electricity, and more particularly to a mixture for the purpose of generating a strong voltage of static electricity while at the same time smoothing the generation of static electricity.

Static electricity means static electricity that is not carried by rubbing objects. In other words, static electricity is electricity that is stationary on an object like friction electricity. For example, rubbing the glass rod with silk cloth creates a positive electric charge on the glass rod, and rubbing the ebonite rod with hair creates a negative charge on the ebonite rod. The opposite concept of static electricity is called voltaic (動 電氣), but generally speaking electricity is not widely used because it means voltaic.

Static electricity has long been known as triboelectric, and since the late 18th century, quantitative research has been carried out by C. Coulomb and others, and has been the basis for the application of electricity and the development of electromagnetics.

You may have noticed some static electricity while taking off your hairy sweater in a dry, dry winter. Fire at a gas station, or a car with oil, or a metal doorknob, or electricity, can all be caused by static electricity. On very low humidity days, tens of thousands of volts of static electricity can be generated when you take off your sweater or walk on a wool carpet. However, since static electricity only has a high voltage and current flows only at a very short time, it is extremely rare to be seriously injured by static electricity.

To prevent static electricity in your room, you should use natural carpeting and cover the door's metal handles with natural fibers. In addition, if static electricity flows into the computer, the internal parts may be abnormal, so the screws connecting the case and the main board serve as grounding to prevent static electricity. You can discharge the static electricity by touching the object slightly without touching the metal object, and then grab the object to reduce the damage of the static electricity to some extent.

Copiers are examples of engineering applications of static electricity that we only feel uncomfortable with. Toner particles that are negatively charged by electric current will only stick to areas where the image is reflected by static electricity. Using this principle, the paper is brought into close contact with each other, and a strong positive charge is applied from the back of the paper.

Electrostatic induction is the phenomenon in which electric charges are induced on the surface of an object when an electric field is brought close to a conductor or a dielectric. It is also called electrostatic induction or electrostatic sensitization.

On the side near the charge, a different kind of charge appears on the opposite side, and on the other side the same charge appears. This phenomenon is used to make a detector to find out the state of charge or to make a Leiden bottle that stores electricity. Unless grounded or touching the ground, the object remains in its original electrical neutral state as a whole.

Approaching a positively charged object to a conductor, such as a metal, the free electrons in the conductor receive the attraction from the positive charge and move toward the charge. As a result, negative charges are induced on the surface close to the charged body, and positive charges are induced on the opposite side. Approaching a negatively charged object will do the opposite. At this time, if you take away the whole body again, it will return to the original neutral state. This is because only the charge distribution is changed while the charge amount is preserved. Therefore, the magnitude of the positive and negative charges induced on both sides of the conductor is the same.

Comb your hair with a comb, then bring it closer to a small piece of paper and the piece of paper will stick to the comb. There are no free electrons in paper-like insulators, but as you bring the charge closer, the arrangement of polar molecules changes. Objects with these properties are called dielectrics. At this time, since the amount of positive and negative charges in the dielectric is the same, there is no change. At both ends, however, molecules are arranged in one direction to induce charge. It is for this reason that dust sticks well to synthetic fibers.

Existing electrostatic generating products have disadvantages that it is difficult to develop products for real life because they do not use the raw materials to maximize the induction of static electricity or static electricity is not generated smoothly or the voltage of generated static electricity is insufficient.

The technical problem to be achieved by the present invention is to provide an electrostatic derivative that overcomes the above-mentioned disadvantages, in particular, is easy to induce static electricity, is inexpensive, reduces cost, and is easy to apply in real life.

"Circular rod for electrostatic induction" according to the present invention is characterized in that the main component is composed of 'Crystalline Carbon and sodium polyacrylate, zirconium oxide'.

When the above-mentioned main components are mixed in a constant ratio to form a mixed composition, and manufactured by incorporating the same into a plastic material again in an appropriate amount, static electricity can be effectively generated.

As described above, the "round rod for electrostatic induction" has an advantage of being able to easily induce static electricity to effectively collect and remove dust and foreign matter.

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, and such modifications and modifications belong to the appended claims.

In order to achieve the above technical problem, the present invention is characterized by consisting of 'Crystalline Carbon and sodium polyacrylate, zirconium oxide' as a main component.

Carbon is an element belonging to group 4B of the periodic table.

Element Code: C, Atomic Number: 6, Atomic Weight: 12.011, Melting Point: 3550 ℃

(Amorphous), Boiling Point: 4827 ° C (Amorphous), Specific Gravity: 1.8 ～ 2.1 (Amorphous)

It is an element known from ancient times, and it is computed as three allotropes, such as amorphous carbon, graphite, and diamond, as a single element substance. Graphite was known in the Middle Ages, and the fact that diamonds were used as gemstones was confirmed by experiments by A.L.Laboisie in 1772 and H.Daviy in 1814. The name diamond derives from the Greek adamas, meaning that it is not conquered from nothing harder, and graphite is derived from the Greek grafein, which means writing from the fact that it has long been used as a writing instrument. Carbon is known to originate from the Gothic hauri and is also known to originate from the jval of Sanskrit, which means combustion. Diamonds are colorless, transparent equiaxed crystals, usually octahedral. Hardness is the highest of the materials. It has a so-called diamond gloss and is sometimes yellow, red, light, green, blue, or black because of impurities. It has a high refractive index of 2.417 and also has high dispersibility. Usually phosphorescent. When air is shut off and heated to 2000 ° C, it turns into graphite. Likewise, when air is shut off and burned at 700 to 900 ° C, carbon dioxide is produced. It is very stable against chemicals such as acids and alkalis. Graphite is a black, hexagonal crystal with metallic gloss. Usually, it is hexagonal plate-like, scaly-shaped, kernel-like, etc., and all have a cleavage. Hardness is 1 to 2 soft. Exhibits significant conductivity. Chemically, it is somewhat more active than diamond, and in air, it ignites and combusts at 500-600 degreeC or more. The powder is treated with concentrated sulfuric acid and concentrated nitric acid to give a greenish brown liquid called graphite acid. Amorphous carbon is a black powder, but consists of very fine crystals of graphite and can be said to be an incomplete form of graphite. Atom arrays are like graphite and are not as scattered as liquids or glass. The particles are porous and only vary in size or shape. It is insoluble in various solvents and is chemically stable, but more active than graphite. It acts on the oxygen and sulfur at the glowing temperature to become carbon dioxide and sulfur dioxide, respectively. At higher temperatures it is easier to react and reacts directly with many elements. For example, acetylene is produced by reacting with hydrogen, carborundum is produced by reacting with silicon, and carbides are formed also with lithium, calcium, iron, aluminum and the like. In addition, it has a reducing effect and takes oxygen from many oxides to form carbon monoxide or carbon dioxide. Coke, charcoal, and grenade are among the amorphous carbons. Diamonds, which have been treated with pure carbon at high temperatures and pressures, have been produced, but have only been made of extremely fine particles. Graphite is obtained by mixing a small amount of sand and iron oxide in anthracite coals, pitch, etc., and heating it to 4,100 ° C in an arc furnace. Amorphous carbon is obtained by incomplete combustion of organic matter and is obtained as carbon black after pyrolysis of hydrocarbons to remove hydrogen. Small amounts can be obtained by dehydrating carbohydrates such as sugar with concentrated sulfuric acid and the like. Diamond is used as a jewel, and it is used for the tip of various drilling, etc. by using a thing with big hardness. For this purpose, low quality bolts such as potential bolts, black diamonds or carbonards are used. Graphite is also used in reactor moderators, electrodes for electrolysis, crucibles, pencils, and gamma agents. Amorphous carbon has a fuel and other uses depending on its shape and properties. The powder is important as an adsorbent, and the fine carbon black is used for fillers of pigments, printing inks and rubber. Carbon has five types of mass 10, 11, 12, 13, and 14. A mass of 12 is usually a stable isotope, but 13 is also stable and present at a rate of 1.108% by volume in the carbon element. Others are unstable and present in trace amounts, but carbons of 14 and 11 mass are used as tracers. In particular, carbon having a mass number of 14 emits β-rays having a half-life of 5750 and is used in archeology and the like for estimating the generation age of mummies.

'Crystalline Carbon' refers to the crystallization of carbon by applying high temperature and high pressure to carbon. Specifically, carbon is denatured at a pressure of about 60,000 to 70,000 atm and a temperature of 1,700 to 2,000 degrees Celsius or higher to convert the carbon into a covalent bond form.

A covalent bond is a chemical bond that refers to a bond formed by two atoms releasing electrons to form electron pairs and sharing them. Also known as electron pair bonds and isopolar bonds. At this time, the spins of the electrons forming each pair of electrons are considered to be opposite directions. For example, in a hydrogen molecule, a hydrogen atom shares two atoms and takes on a helium type electronic structure. In addition, ionic bonds that are bonded by positive and negative ions between positive and negative ions are called bipolar bonds. In covalent bonds, there is no such difference between two atoms. Also known as 結合). Quantum mechanics explains that two electrons enter together in the exchange energy generated by exchanging electrons, or in a stable bond orbital between two atoms. Covalent bonds are found in most organic and some inorganic compounds. Atoms such as hydrogen, carbon, oxygen, and sulfur tend to form covalent bonds. In the schematic representation of covalent bonds, electrons involved in the bond are often represented by dots, such as H: H, Cl: Cl, and the like. One pair of electrons is represented by one bond line, and may be represented as H-H, O = O, or N≡N. In bond strength, triple bonds are stronger than double bonds, and double bonds are stronger than single bonds. Covalent bonds, like ionic bonds, are typical and extreme bond forms, and most of the actual bonds have their intermediate character. For example, in the case of hydrogen chloride, the probability distribution of the electrons is biased toward the chlorine for some time, which is a covalent bond with the nature of ionic bonds.

'Crystalline' is a term used to mean crystals. Crystals mean 'particles with regular grids'.

Crystals are evidence that the atoms or ions that make up the crystals are in regular order internally. Internally, however, members and ions have a regular arrangement, but they cannot form crystals externally for various reasons. Regardless of the external crystalline form, the members have a regular internal arrangement. However, in mineralogy, physics, chemistry, metallurgy, biology, etc., it is usually called crystalline even when the crystalline form is not fully developed. On the other hand, solids in which members or ions are arranged irregularly are called amorphous. Examples of amorphous materials include glass and protein stones. When viewed with the naked eye, the absence of mineral particles does not indicate that they are amorphous. Minerals produced as powders are also usually crystalline.

Crystals can be divided into several types according to the chemical composition, chemical bonds, and the like.

Ionic crystals are crystals formed by the ionic bonds of cations and anions. Salts of metals such as sodium chloride composed of Na + and Cl- form ionic crystals well. Among the materials that appear to be ionic crystals, many chemical bonds exhibit covalent bonds.

Metal crystal is a crystal made of metal element by metal bond. It is mainly composed of crystal structure such as body centered cubic structure, face centered cubic structure and hexagonal close structure.

Covalent crystal is a crystal in which valence is connected by covalent bond. Diamond and silicon carbide are good examples. It is quite hard and its melting point and boiling point is very high.

Molecular crystals are crystals formed by weak bonds mainly caused by van der Waals forces. Most organic compounds such as inert gas elements, non-metal inorganic compounds such as oxygen, hydrogen and iodine, and naphthalene are examples of these.

The crystals often form perfectly crooked malformations, although they may appear completely in shape. Crystals also form pillars, needles, fibers, leaves, and wood boards, depending on the production environment. On the other hand, the same minerals but different crystal forms are called normal, and the same type of crystal and crystal are combined with each other according to regularity. Twins are formed when they are produced by precipitation directly in solution, or by mechanical forces after minerals are produced. The twin can be known by the fact that the face meets the crystal surface and forms a recessed angle. The crystal used for the electronics industry, such as a semiconductor, generally uses the thing synthesize | combined by the laboratory, without using a natural acid crystal.

Covalent crystallization of carbon through mesh covalent bonds leads to a diamond-like structure, which dramatically improves electrical conductivity. Although it is lower than diamond, but shows higher conductivity than copper, 'Crystalline Carbon' can provide high efficiency in inducing static electricity.

Sodium Polyacrylate is a food additive for increasing the adhesiveness and viscosity of foods, enhancing the emulsion stability, and improving the physical properties and feel of foods. It is widely used as a thickener, stabilizer, coagulant, wetting agent, emulsion dispersant, and tissue improver in food. White powder with no smell and taste. Sodium polyacrylate is highly hydrophilic and hygroscopic as a polymer in sodium acrylate. It slowly dissolves in water to form a viscous transparent gel solution, insoluble in all organic solvents. In the case of 0.5% solution, the viscosity is about 1000 cps, resulting in a highly viscous solution because the molecules increase due to the ionic phenomenon caused by a large number of anions in the molecule. In particular, since the viscosity is large and the addition amount is at least, and the heat resistance is large, it does not decompose to about 300 ° C., so that it is easy to use in foods requiring heat treatment. In addition, since there is no fear of corruption or deterioration like natural products, it is excellent in storage. However, divalent or higher metal salts, such as calcium and magnesium, cause white precipitates, reduced viscosity, and precipitation due to certain concentrations of acid (pH 4). This is because sodium polyacrylate is an electrolyte, and thus is easily affected by acid or other metal ions.

Sodium polyacrylate is easily ionized as an electrolyte. Therefore, induction of static electricity by using sodium polyacrylate can easily generate static electricity.

Zirconium (Zr) is a silvery white or off-white shiny metal and belongs to the hexagonal system. It is black powder which is amorphous, and powder has a low flash point and is easy to explode when mixed with an oxidizing agent. It is easy to oxidize at normal temperature, but it is easy to become zirconium oxide at high temperature. Insoluble in acids and alkalis, soluble only in aqua regia and hydrofluoric acid. Its properties are similar to titanium, and its separation from hafnium is difficult, especially because its chemical properties resemble hafnium. Its melting point is higher than that of titanium, but its heat resistance is weaker than that of titanium, and its tensile strength is lower than 400 ℃.

Zirconium oxide (zirconium) is an oxide of zirconium. It is a yellowish white or brown substance made by heating zirconium hydroxide. It is used as a special ceramic or crucible fireproofing, heat-resistant utensils, glass heat-resistant and corrosion-resistant ceramic raw materials. Zirconium oxide extends the lifespan of equipment made for the purpose of electrostatic induction and has the characteristic of facilitating the generation of static electricity.
