Description

  The present invention relates to a cleaning agent suitable for cleaning articles such as interiors of automobiles and buildings, office automation equipment, and toys, which are frequently contacted by people.

Conventionally, the active water obtained by processing by the reverse osmosis membrane method has been used for cleaning various articles (cleaning cleaning and wiping cleaning).
In the reverse osmosis membrane method, for example, when a water tank is divided into two compartments by a semipermeable membrane, when saline is injected into one compartment and pure water is injected into the other compartment, the pure water side naturally decreases, The water side increases and the saline solution is diluted. This is because the semipermeable membrane has extremely small pores, and sodium ions and chloride ions in the saline solution, and these ions and water molecules are associated with each other. This is because the aggregate cannot penetrate the pores, and only small water molecules in the cluster (an aggregate composed of multiple water molecules) permeate the semipermeable membrane and move between the two compartments. Using this semipermeable membrane, raw water (containing a small amount of mineral ions etc. in tap water) is injected into only one compartment, and the semipermeable membrane is forced to permeate by pressurizing the raw water. At this time, while removing raw water-containing impurities in the semipermeable membrane, the cluster is divided, It generates a sex water, a method was set to be accumulated in compartment on the other side.
Since this active water has small clusters of water molecules constituting it, it has a low surface tension and excellent permeability, and penetrates into the fine gap between the article to be cleaned and the dirt adhering to it. Therefore, the detergency is high and the use of a detergent such as an organic surfactant can be eliminated.
However, since the formation of clusters is primarily due to the inherent polarity of water molecules, after the generation of active water, the clusters gradually re-grow, and the cleaning power decreases with time. I couldn't save it.
By the way, like the above-mentioned active water, alkaline ionized water is an example of water that does not require detergent and is environmentally friendly and has high detergency.
However, alkaline ionized water is applied to the raw water and adjusts the association state and charge state of water molecules to provide detergency, so it suddenly returns to normal water when contacted with the article to be cleaned. Moreover, even if it was in contact with air in the reservoir state, it gradually returned to the original water and the detergency could not be maintained for a long time.
Then, the washing water which invented the alkaline ion water produced | generated with the electrolysis apparatus further by the reverse osmosis membrane method, and produced | generated the activated water obtained again by electrolytic treatment was invented (refer the following patent document 1). .
This washing water was designed to prevent the electrons from being easily discharged into the air by preventing impurities from being contained by removing the contained impurities while setting the pH value to 12 or more. .

  However, even if the product of the above-mentioned Patent Document 1 is used for an article that easily adheres to dirt due to static electricity, such as an air conditioner such as an air conditioner, an OA machine, etc. In places where it must be re-attached and the appearance must be kept clean, such as in a store, etc., cleaning must be repeated frequently. In this respect, there is no difference from the case of using a conventional surfactant. It was.

  In view of the above problems, the present invention produces raw water by treating raw water by a reverse osmosis membrane method, prepares a cleaning agent by adding sodium silicate to the active water, and cleans the article to be cleaned with the cleaning agent. In addition to cleaning or wiping and cleaning, a film made of sodium silicate is formed on the surface of the article to be cleaned, and the film solves the above problem by preventing the adhesion of dirt.

In short, since the present invention was prepared by treating raw water by a reverse osmosis membrane method to produce active water and blending the active water with sodium silicate, such a detergent has high osmotic power and removes dirt very easily. In addition, by performing cleaning, a coating of sodium silicate (so-called water glass) can be formed on the surface of the article to be cleaned, and the coating makes it difficult for dirt to adhere, thereby reducing the number of cleanings.
In addition, the surface of the water glass coating is highly hydrophilic and can easily penetrate even with normal water between the coating surface and the attached dirt, making it easier to clean the next time after the first coating is formed. I can do it.
In addition, since the generation of static electricity is reduced by the water glass coating, for example, if OA equipment, home appliances, and the like are wiped and cleaned with the cleaning agent, the amount of dirt adhered thereafter can be drastically reduced.
Furthermore, by containing water glass in the active water, the growth of clusters is suppressed and the clusters are kept small, so that the cleaning power is maintained over a long period of time and the usability is good. Since it is harmless to the human body, it is highly safe and has practical effects such as being suitable for cleaning personal items that have many opportunities for human contact.

Hereinafter, the cleaning agent of the present invention will be described in detail.
The cleaning agent of the present invention is prepared by treating raw water by a reverse osmosis membrane method to produce active water and blending the active water with sodium silicate.

The raw water may be ordinary tap water in addition to distilled water and purified water, and the active water is obtained by applying a pressure to the raw water to forcibly permeate the semipermeable membrane (so-called reverse osmosis). This active water is modified into water of a smaller cluster by removing impurities such as various ions contained in the raw water, ultrafine suspended particles, etc., and by dividing the water molecule cluster. Is.
In addition, as a reverse osmosis membrane apparatus, SW-150 type marketed from Pure Water, Inc. is mentioned, for example, What is necessary is just to select and use suitably from such a commercially available thing.

Sodium silicate is also referred to as sodium silicate or water glass. As types, sodium metasilicate (Na ₂ SiO ₃ ), sodium orthosilicate (Na ₄ SiO ₄ ), sodium metadisilicate (Na ₂ Si ₂ O ₅ ) There are sodium metatetrasilicate (Na ₂ Si ₄ O ₉ ) and the like, and there are anhydrides and hydrates, and any ordinary commercially available one may be selected and used.

  When the amount of sodium silicate is less than 5% by weight, it is difficult to form a sodium silicate coating on the article to be cleaned, and when it is more than 35% by weight, it is difficult to stabilize by dissolving in active water. In order to easily cause precipitation, the composition of each component is preferably in the range of 65 to 95% by weight of active water and 5 to 35% by weight of sodium silicate.

Since the cleaning agent of the present invention has the above-described configuration and is mainly composed of reverse osmosis membrane water, the surface tension is small and the osmotic power is high. By spraying and washing, spraying a small amount of cleaning agent on the article, and wiping with a cloth, paper, etc., dirt is removed very easily, and after cleaning, reverse osmosis membrane water evaporates from the surface of the article to be cleaned and is dried. However, the sodium silicate contained in the cleaning agent remains on the surface of the article to be cleaned, and a sodium silicate film is formed. This film reduces the adhesion of dirt.
In addition, by containing sodium silicate in the reverse osmosis membrane water, the enlargement of the water molecule cluster size is suppressed, and the detergency is maintained for a long period of time.
