Description

TECHNICAL FIELD The present invention relates to a water modifier for use in a cleaning apparatus that cleans the surfaces of automobiles, railroad vehicles, ships, etc. only by spraying water and forms a film on the surface to be cleaned, and a method for producing the same.

BACKGROUND ART Conventionally, the surfaces of automobiles, railroad vehicles, ships, and the like are polluted by rainfall, adhesion of dust, and the like, and thus require regular cleaning.
In particular, when washing an automobile or the like, it is common practice to wash the car with a detergent and then apply wax.
In recent years, there has been some practice of forming a film using a specially blended polymer, but this has the disadvantage of high cost.

Therefore, the present applicant has developed a water modifier in which a ceramic powder raw material, which is a mixture of tourmaline powder, borax, and sodium silicate powder, is adhered to the surface of a ceramic carrier and fired to form a tourmaline-containing film (for example, See Patent Document 1).

This water modifier has the following effects (1) to (3).
(1) This water modifier filling can be used permanently and for a long period of time, so that only the washing water circulating in the cartridge filled with this water modifier can be used to wash automobiles and form a silica borate film. , labor and cost can be greatly reduced.
(2) Since the washing water is activated by the circulation between the water modifiers, it is possible to separate the dust adhering to the surface of the automobile or the like and increase the washing power, thus eliminating the need for detergents. can prevent environmental pollution.
(3) The cleaning water that flows between the water modifiers contains silica borate, which is a component of the water modifiers, and is sprayed onto the surface of automobiles, etc., and tourmaline is generated by electrodeposition due to the electric charge. By forming a silica borate film by firmly adhering to the surface and adhering to fine irregularities on the surface, the silica borate film is vitreous, so it has high water repellency and does not easily adhere to dirt. In addition to omitting the trouble of applying wax, washing of automobiles, etc. after formation of the silica borate film can be done only with water, making detergents and chemicals unnecessary.

However, in this tourmaline-containing coating, since sodium silicate powder is used, although the sintering adhesion with the ceramic carrier is sufficiently demonstrated, it cannot be denied that it may peel off from the ceramic carrier depending on the application. .

Japanese Patent No. 3612442

The present invention is a water modifier for use in a cleaning apparatus that saves labor and costs cleaning work and eliminates the need for chemicals such as detergents and waxes, and comprises sintering a carrier and a tourmaline-containing coating. To provide a water modifier which has strong fixation to prevent peeling of a tourmaline-containing film from a carrier, and a method for producing the same.

In view of the undeniable problem that the tourmaline-containing film may peel off from the carrier in the case of sodium silicate powder, the present invention has been made by attaching a ceramic powder raw material containing tourmaline, a melting material, and petalite powder to the surface of a ceramic carrier. By sintering to form a tourmaline-containing coating, the sintering adhesion of the support and the tourmaline-containing tourmaline-containing coating is further enhanced by the lithium silicate contained in the petalite powder, compared with a conventional tourmaline-containing coating using sodium silicate. The water modifier can be used semi-permanently and for a long period of time by being strengthened.
Also, by firing at 1000° C. or less during the formation of the tourmaline-containing film, it is possible to prevent tourmaline from changing its crystal form and losing its electrical properties.
When this water modifier is used in a washing device, the borate silica eluted from the tourmaline-containing film is contained in the source water, and the action of the tourmaline electrifies the borate silica, and the source water becomes electrically charged. Since it is decomposed and water-reformed into active water, the detergency is improved and the contained silica borate adheres to the surface of the object to be cleaned by electrodeposition.

In short, as a whole, the activated water containing silica borate obtained by passing water through a water activation tank filled with a granular water modifier is ejected onto the surface of an automobile or the like to clean the surface and form a silica borate coating. In the water modifier, the tourmaline-containing film is sintered on the surface of the carrier formed by sintering a mixture of zeolite and bachanite, so the water modifier can be used semi-permanently for a long period of time. Since the washing water flowing through the water modifier-filled cartridge is used only for washing automobiles and forming a silica borate film, labor and cost can be greatly reduced.
In addition, since the washing water is activated by the circulation between the water modifiers, the dust adhering to the surface of the automobile or the like can be removed and the washing power can be increased, thus eliminating the need for detergents. Environmental destruction can be prevented.
Furthermore, the washing water that flows between the water modifiers contains silica borate, which is a component of the water modifiers, and is sprayed onto the surface of automobiles, etc., and tourmaline is generated. and adheres to the fine irregularities on the surface to form a silica borate coating. Since the silica borate coating is vitreous, it has high water repellency and is less likely to be stained, In addition to saving the trouble of applying wax, washing of automobiles, etc. after formation of the silica borate film can be done only with water, and detergents and chemicals can be made unnecessary.

In addition, in the invention described in the claims, a ceramic powder raw material containing tourmaline, a melting material, and petalite powder is adhered to the surface of a ceramic carrier and fired to form a tourmaline-containing film. The sintering adhesion of the tourmaline-containing coating to the carrier surface can be strengthened by the presence of irregularities on the surface of the ceramics.
And by unevenly distributing tourmaline only on the surface layer of the water modifier, it is possible to bring the tourmaline and the source water into contact with each other efficiently, improve the water activation efficiency, and promote the elution of silica borate. Moreover, it is possible to reduce the production cost by reducing the tourmaline content required for the water modifier.

In addition, the tourmaline-containing coating can facilitate sintering adhesion of the tourmaline-containing coating to the carrier below the temperature at which the melting agent lowers the sintering temperature and the tourmaline loses its electrical properties, and Lithium silicate, which is the main component of petalite, can reliably prevent the peeling of the tourmaline-containing coating from the carrier, and can improve the impact resistance of the tourmaline-containing coating. Lithium silicate can increase the elution amount of silica borate.

In addition, before the tourmaline-containing coating is sintered, the carrier is formed by molding and firing ceramic powder obtained by pulverizing and mixing zeolite and Bacchanite. The sintering adhesion of the tourmaline-containing coating to the carrier surface can be strengthened, and the carrier can be sintered at a temperature higher than the temperature at which tourmaline loses its electrical properties. Since the contained minerals act as a fusing agent, when mixed with zeolite, the carrier can be easily sintered and the strength of the carrier can be improved.

In addition, since the water modifier manufactured by the manufacturing method according to claim 1 or 2 and the secondary water modifier containing magnesia as a main component are used in combination, the source water passing through the water activation tank of the washing device By eluting minerals, the water quality of the active washing water is made alkaline to improve the detergency, and the water is activated by the same action as the water modifier formed with the tourmaline-containing film to improve the detergency. can be achieved.

Alternatively, a ceramic powder raw material containing tourmaline, a molten material and petalite powder is adhered to the surface of a ceramic carrier , fired to form a tourmaline-containing film, and zeolite and bachanite are pulverized and mixed. Since the powder is molded and fired to form the carrier, the new manufacturing method as in the present application is mainly composed of simple steps, and the process of the ceramic industry can be diverted, so it is possible to manufacture water modifiers. Furthermore, most of these raw materials can be obtained stably and in large quantities from natural ores, etc., at a low cost.

It is the longitudinal cross-sectional view seen from the front side of the main body. It is the longitudinal cross-sectional view seen from the left side of the main body. It is a figure explaining the boric-acid silica film formation condition in the surfaces, such as a motor vehicle. 1 is a schematic cross-sectional view of a water modifier; FIG.

An embodiment of the present invention will be described below with reference to the drawings.
A cleaning device 1 in which a water modifier manufactured by the method for manufacturing a water modifier of the present invention is used is provided with a water activation tank 3 and a water supply device 4 for high-pressure water in a base case 2 .

The water activation tank 3 has a detachable lid 5 on the top, and replaces a cartridge 7 filled with a large number of spherical (granular) water modifiers 6, 6a, . . . freely worn.
A water supply port 8 is provided at the bottom of the water activation tank 3 to which a water supply pipe 8a of tap water to which water supply pressure is applied is directly connected, and the upper part of the water activation tank 3 and the water supply device 4 are communicated with each other by a connecting pipe 9. .
The diameters of the water supply port 8 and connecting pipe 9 provided on the supply side and the drain side of the water activation tank 3 are smaller than that of the connecting pipe 9 on the downstream side of the drain.
Also, a high-pressure hose 11, a gun 12 and a nozzle 13 are connected in sequence to a high-pressure water delivery port 10 of the water supply device 4. As shown in FIG.

The water activation tank 3 is provided with a discharge port 14 for taking out the activated water to the outside, and the base case 2 is provided with wheels 15, a handle 16, legs 17, a switch, a power plug, etc., and is mounted on the upper surface. A placement section is provided.

Next, a method for washing an automobile or the like using the water modifier according to the present invention will be described.
A tap water supply pipe 8a is connected to a water supply port 8 of a water activation tank 3 in which a freely water-permeable cartridge 7 containing a large number of granular water modifiers 6, 6a, . . . A high-pressure hose 11, a gun 12 and a nozzle 13 are sequentially connected to the cleaning water outlet 10, and the water supply device 4 is operated.

When the cleaning device 1 starts operating, the source water (tap water) supplied from the water supply port 8 passes through the water activation tank 3, and the silica borate S1 eluted from the tourmaline-containing coating 18 of the water modifiers 6, 6a, . . . , S2 . Water is fed from the tank 3 to the water feeder 4 via the connecting pipe 9 .

The activated water containing silica borate that has flowed into the water supply device 4 is ejected from the nozzle 13 through the high-pressure hose 11, the gun 12, etc. onto the surface W of the automobile (including the glass surface and other surfaces) as high-pressure washing water. The active cleaning water cleans the dirt adhering to the surface W, and the silica borate S1, S2, ... contained in the cleaning water adheres to the surface W due to the electric charge and enters the fine unevenness of the surface W. , forming a vitreous thin boric acid silica coating M1 on the surface W;

Next, detailed actions in the basic cleaning method described above will be described.
, 20, 20a, . . . , 20, 20a.

The components of the first type of water modifiers 6, 6a, . These water modifiers 6, 6a, . . . contain borate silica S1, S2, . and mixed into the source water.

The tourmaline that forms the tourmaline-containing film 18 adhered to the surfaces of the water modifiers 6, 6a, . It has the property of generating an electric charge (piezoelectricity, electric potential, etc.) on the surface.
In addition, tourmaline easily elutes the silica borate S1, S2, . Therefore, when the tourmaline generates an electric charge, the surfaces of the silica borate S1, S2, etc. mixed in the source water are charged with an electric charge, and the silica borate S1, S2, . . . It seems that the effect is provided.
Moreover, it is believed that the electric charge generated by the tourmaline causes electrolysis of the water passing around the water modifiers 6, 6a, .

The components of the secondary water modifiers 20, 20a, etc. of the second type are formed by sintering magnesia, and the secondary water modifiers 20, 20a, . . . It has an alkaline action.
In addition, like the water modifiers 6, 6a, . It is thought that the source water is activated by the following actions due to the contact action with the water passing through.
For example, when water comes into contact with the secondary water modifiers 20, 20a, . . . , static electricity is generated and the potential changes. , which seems to be activated by water.

, 20, 20a, . Acting on water structures such as ionic bonds and hydrogen bonds, clusters (bonds of water molecules H ₂ O) become smaller, and the water structure becomes hydrophobic and activated. Contaminants adhering to the surface W such as are included in the water structure, and the cleaning action is increased.

In addition to the action of the water reforming materials 6, 6a (including the secondary water reforming materials 20, 20a, the same applies hereinafter in the washing action), the water activation is caused by the pressure acting on the source water. It flows into the water activation tank 3 filled with the material 6, 6a and changes, or the pressure increases (pressure change ), the viscosity of water changes, water structure changes occur, and pressure changes occur.
In addition, since the gaps between the large number of granular water modifiers 6, 6a, . . . , the water pressure around the water modifiers 6, 6a, . These running water actions promote charge generation in tourmaline and elution of silica borate S1, S2, .

Then, when the silica borate-containing activated washing water is jetted onto the surface W of an automobile or the like, dirt attached to the surface W is removed by the pressure water jetted at high pressure from the water supply device 4, or the dirt is contained and removed by the activated water. .
At the same time as the cleaning action, the electrified silica borate S1, S2, etc. contained in the cleaning water are firmly attached to the surface W of the automobile or the like by the electrodeposition action by the electric charge generated by the tourmaline. Since the surface W such as a painted surface or a glass surface has innumerable fine irregularities, the silica borate S1, S2, etc. contained in the washing water enter into the irregularities and adhere to the surface W. A thin borated silica coating M1 is formed.
Since the boric acid silica film M1 is also vitreous and has a water-repellent surface, it is difficult for dirt to adhere.

Finally, a preferred embodiment using the cleaning method described above is described.
When the cleaning method of the present invention is performed for the first time, if the dirt on the automobile or the like is not sufficiently removed, the dirt will be firmly embedded in the silica borate coating M1. It is essential.
Further, when the cleaning according to the present invention has been carried out even once, only water cleaning is sufficient, but by carrying out the cleaning according to the method of the present invention a plurality of times, new coatings M2, M3, . . . Formed, glossiness and water repellent effect are improved.

In addition, according to the cleaning apparatus and cleaning method described above, the silica borate coatings M1, M2, . . . Etc. to facilitate care.
Further, by using a detergent for the first cleaning, even if the surface W of an automobile or the like is dirty, the detergent can be used together to remove the dirt and prevent the dirt from remaining in the silica borate coatings M1, M2, . . . .
In addition, the cartridge 7 filled with the water modifiers 6, 6a, . At the same time, the water modifiers 6, 6a, . . . are easily replaced.
In addition, by making the diameter of the connecting pipe 9 smaller than the diameter of the water supply port 8, the three actions of charge generation (charging), inclusion of silica borate, and activation are promoted by pressure change, and the effect of the washing water is improved. improve.
Further, by providing the water activation tank 3 with a discharge port 14, the silica-borate-containing activated water can be taken out separately into a bucket or the like, thereby improving usability.

Next, an example of a method for manufacturing the water modifiers 6, 6a, . . . according to the present invention will be described.
Basically, powder of ceramics (all ceramic raw materials including ceramic raw materials such as kaolin and feldspar, fine ceramic raw materials such as alumina and zirconia, etc.) is formed into a substantially spherical shape or granulated, A carrier 19 is formed by sintering, and then a ceramic powder raw material containing tourmaline (tourmaline) is adhered to the surface of the carrier 19 and sintered to form a tourmaline-containing film 18 .

Specifically, first, zeolite and Bacchanite are pulverized and mixed, then molded or granulated into a substantially spherical shape, fired at 1000 to 1100° C. to form the carrier 19, and then tourmaline powder, borax, and petalite powder. are put into a pan-type tumbling granulator together with the carrier 19, and mixed while adding an appropriate amount of water to obtain a ceramic powder raw material containing tourmaline and petalite powder on the surface of the carrier 19. It is deposited and fired at 600-1000° C. to form a tourmaline-containing coating 18 .

Although the carrier 19 formed by sintering as described above is desirable in terms of hardness and strength, the carrier 19 may be an unsintered carrier 19 using a ceramic raw material that has been roughly pulverized to a suitable particle size.
In addition, when tourmaline is heated at a temperature exceeding 1000° C., it changes its crystal shape (transition) and loses its electrical properties. There must be.
Also, in order to firmly sinter the ceramic powder raw material containing tourmaline and petalite powder and to adhere it to the carrier 19 to form the tourmaline-containing film 18, it is necessary to bake at 600° C. or higher. confirmed.

Further, when the tourmaline-containing film 18 is formed by mixing tourmaline powder, borax, and petalite powder, the amount of tourmaline that adheres to the surface of the carrier 19 is insufficient when the tourmaline powder is 30% or less by weight. When it is 70% or more, borax and petalite acting as a fusing agent are insufficient, and it becomes difficult to sinter and fix tourmaline to the surface of the carrier 19 at 1000 ° C. or less. It was confirmed that when powder is 30-70%, borax is 50-20%, and petalite powder is 25-10%, the tourmaline-containing film 18 can be firmly adhered and formed, and a practically sufficient water reforming effect can be obtained. was done.

Also, when the carrier 19 is made by pulverizing and mixing 50% zeolite and 50% Bacchanite by weight ratio, good sintering results were confirmed at 1000 to 1100° C., but the carrier 19 The raw materials and firing temperature are not limited to the above, and other ceramic raw materials may be used by mixing them as appropriate. When using other ceramic raw materials, consider the characteristics of the selected ceramic raw materials, and sufficiently firmly It is desirable to set it so that it can be sintered.

The size of the carrier 19 may be appropriately adjusted according to the size of the cleaning device 1 to be used, etc. At that time, the thickness of the tourmaline-containing coating 18 formed on the surface of the carrier 19 is determined by considering the particle size of the carrier 19. For example, when the particle diameter of the carrier 19 is 5 mm, the tourmaline-containing coating 18 is formed with a thickness of 0.2 mm, and when the particle diameter of the carrier 19 is 30 mm, the tourmaline-containing coating 18 is formed with a thickness of 2 mm. do it.

According to the method of manufacturing the water modifiers 6, 6a, . It allows the sintering of the carrier 19 at higher temperatures, but not below the temperature at which it loses its mechanical properties.
Further, since tourmaline powder, borax, and petalite powder are mixed, the borax and petalite powder, which are fusing agents, lower the sintering temperature of the tourmaline-containing coating 18 .
Further, by forming the carrier 19 by pulverizing and mixing zeolite and Bacchanite having an adsorptive action, a carrier 19 having excellent adsorptive properties can be obtained.
In addition, since Bacchanite contains a large amount of minerals (metal oxides, etc.) in its composition, when mixed with zeolite, the minerals act as a melting agent to lower the sintering temperature of the carrier 19 .
