Description

  The present invention relates to a glass polishing agent and a glass polishing method for removing dirt adhered to a glass surface such as a mirror and a window glass, and a rust removing agent and a rust removing method for removing rust generated on the surface of a metal product. It is.

  The surface glass of mirrors installed in bathrooms and bathrooms is covered with tap water, soap, shampoo, etc., and when it dries, white stains called scales and scales tend to stick. This white stain is mainly caused by mineral components such as calcium, magnesium, and silica in tap water. Of these, silica compounds are the same quality as the surface glass. Even if acid or acetic acid is used, it cannot be easily removed.

  In the past, for example, the surface of a cloth was coated with an abrasive such as alumina to grind the surface of the glass with an abrasive such as alumina. Also, for example, Patent Document 1 below discloses a glass polishing agent that removes dirt by mixing organic acid, organic hydrochloric acid, chelating agent, etc. with alumina powder, and applying this composition to a mirror surface and wiping with a cloth. ing. Patent Document 2 below proposes a cleaning system in which a diamond pad is attached to the head of a cleaning machine, and floor stones and glass are polished and cleaned while water is supplied.

Japanese Patent Laid-Open No. 9-176693 JP 2007-152189 A

  By the way, the conventional method using an abrasive such as alumina requires a lot of time and labor since it is necessary to polish the glass surface by rubbing it strongly to remove the adhered silica dirt firmly. The work is not easy. Moreover, since the glass polish of the said patent document 1 is fundamentally by grinding | polishing of the glass surface by an abrasive | polishing agent, it cannot remove even the stain | pollution | contamination which entered between the particles of the glass surface layer. Furthermore, since the method of Patent Document 2 requires a diamond pad and an electric cleaning machine, it is costly, and is not limited to removing dirt from the silica compound fixed to the glass surface.

  Therefore, the present invention has been devised to solve these problems, and the main purpose thereof is to easily and safely remove dirt adhered to the glass surface without using an abrasive or a surfactant. It is to provide a novel glass polishing agent and glass polishing method. Another object of the present invention is to provide a novel rust remover and rust remover that can easily and safely remove rust generated on the surface of a metal product with almost the same components as the glass polish. It is.

  As described above, the present inventor cannot easily remove the silica compound just by lightly polishing the glass surface with an abrasive such as alumina as described above. It would not have been cleaned unless it was polished to a considerable depth. This is because the silica compound is not only fixed to the glass surface, but also a part of it penetrates into the glass from the spread of the glass particles due to aging deterioration of the glass surface, and it is dried and fixed as it is I think this is the cause.

  Then, in order to solve the said subject, this invention is a glass polishing method which makes a bamboo vinegar contain citric acid in a predetermined ratio, and a glass polishing method using the same. Then, a glass polishing agent mixed with a predetermined amount of citric acid in this bamboo vinegar and stirred is sprayed on the surface glass of a mirror installed in a bathroom or bathroom, and after a predetermined time (1-2 minutes), By simply sliding the glass surface so that it is rubbed lightly with a sliding material, scaly white stains due to the silica compound fixed to the glass surface can be dissolved and easily removed.

  That is, not only the silica compound fixed to the glass surface but also the silica compound that penetrates into the interior from between the particles of the glass surface layer and does not reach the abrasive can be chemically dissolved and removed. . Moreover, it becomes difficult to become dirty by removing the silica compound that has entered the inside of the glass, and the effect of removing the stain can be exhibited over a long period of time. And since this glass polish is weakly acidic, even if it touches skin directly, it can work safely, without harming.

  Moreover, the liquid which contained citric acid in the bamboo vinegar in this way can be used for a rust removal agent and a rust removal method using the same. That is, this rust remover is sprayed on the surface of a metal product where rust is generated, and the rust stain can be easily removed by rubbing with a cloth, sponge, scrubbing, etc. after a predetermined time (5 to 6 minutes). . Moreover, if it is a small metal product, the rust which generate | occur | produced on the surface can be easily removed only by immersing in the liquid of this rust remover for several tens of minutes-several hours.

  According to the glass polishing agent of the present invention, calcium or magnesium compounds can be obtained by spraying on a glass surface such as a mirror without using an abrasive or a surfactant and then sliding lightly with a sliding material. Of course, scaly white stains due to the silica compound fixed to the surface glass can be dissolved and easily removed. Moreover, since this glass polish is weakly acidic, even if it directly touches the skin, it can be safely operated without causing any immediate harm.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. As shown in FIG. 1, the glass polish 100 according to the present invention has a composition containing citric acid in bamboo vinegar. Citric acid (C ₆ H ₈ O ₇ ) is an organic compound contained in citrus fruits and is one of the hydroxy acids. Traditionally, water stains such as toilets, baths, and kitchens (residues of detergent and water stains, etc.) ) Is known for its cleaning effect. These water-borne stains are alkaline, whereas citric acid is acidic, and it is said that neutralizing alkaline stains exerts a cleaning effect. Citric acid may be either an anhydride or a crystal (hydrate).

  On the other hand, bamboo vinegar liquid is obtained by cooling and liquefying exhaust gas generated when making bamboo charcoal, and has been conventionally said to have deodorizing, sterilizing, antibacterial and insecticidal effects. Among them, more than 200 kinds of chemical substances are contained, and in particular, the main components are moisture and tar content, but in addition to that, about 5% acetic acid, each of 0. About several percent formic acid and propionic acid, about several hundred ppm each of phenols and alcohols, orthocresol, metacresol, paracresol and the like are included. Bamboo vinegar has a hydrogen ion concentration (pH) of about 2.5 to 3.5, and is weakly acidic without causing any harm even if it directly touches the skin. The specific gravity is almost the same as that of water. In addition, although this bamboo vinegar liquid has a component slightly different depending on the production area and the kind of bamboo, there is no significant difference depending on the production area and kind, and any bamboo vinegar liquid can be used.

  Then, a glass polish (liquid) mixed with a predetermined amount of citric acid in this bamboo vinegar solution and stirred is sprayed on the surface glass of a mirror installed in a bathroom or bathroom, and after a predetermined time has passed, the glass surface is By simply sliding lightly with a sliding material, not only calcium and magnesium compounds but also scaly white stains caused by silica compounds fixed to the surface glass can be dissolved and easily removed. This is because the silica compound fixed to the glass surface is removed by the physical action of sliding of the sliding material, and the silica compound that has penetrated into the glass from between the glass particles on the surface is a component of the silica compound. It is thought that it is dissolved and removed by the chemical action due to. Moreover, since this glass polish is weakly acidic, even if it directly touches the skin, it can be safely operated without causing any immediate harm.

  More specifically, by adding solid (powder) citric acid at a ratio of 10 g to 25 g to 100 ml of this bamboo vinegar solution, an excellent dirt removing effect can be exhibited. That is, as shown in the examples described later, when the amount of citric acid is less than 10 g, it takes time to obtain a sufficient removal effect, and when it exceeds 25 g, the removal effect falls. The silica compound dissolution and removal effect of the glass polish of the present invention having such a composition, that is, the chemical action is under intensive study, but when using wood vinegar instead of bamboo vinegar, bamboo Since the removal effect as high as vinegar cannot be obtained, it is considered that the difference in the component or the amount of the component is influencing.

  The wood vinegar is a liquid obtained by cooling and liquefying the exhaust gas generated when making charcoal, similar to the bamboo vinegar, and the components are basically the same. However, bamboo vinegar has less tar content, acetic acid and alcohol content than wood vinegar, and conversely has more formic acid and phenols. I think that it has a big influence on the effect.

  Further, the liquid containing citric acid in the bamboo vinegar can be used as a rust remover. In other words, this rust remover can be sprayed around rusted metal products such as scissors and kettles and stainless steel sinks in the kitchen and rubbed with a sliding material after 5-6 minutes to easily remove the rust stains. It becomes. Moreover, if it is a small metal product, the rust which generate | occur | produced on the surface can be easily removed only by immersing in the liquid of this rust remover for several tens of minutes-several hours.

Next, examples and comparative examples of the mirror polish 100 according to the present invention will be described.
(Examples 1-14)
As shown in FIGS. 3 and 4, 5 g, 10 g, 15 g, 20 g, 25 g, 30 g, and 35 g of powdered citric acid (hydrate) are mixed and stirred for 100 ml of commercially available bamboo vinegar solution. Seven types of samples (mirror polish) were prepared. Then, using these seven types of samples, an experiment for confirming the effect of removing dirt on two types of mirrors A and B each having a white scaly silica compound fixed on the surface thereof was conducted.

  As an experimental method, as shown in FIG. 1, each material is put in a spray container 200 having a capacity of 200 ml and sprayed uniformly on the surface of the mirror 300 from a distance of about 30 cm toward the surface of the mirror 300 in a vertical state. Using a diamond cleaner manufactured by Daiso Sangyo Co., Ltd., the surface of the mirror 300 was lightly rubbed with a uniform force within a range of 10 cm × 10 cm for a predetermined time to remove scaly white stains adhering to the surface.

  Thereafter, the surface was washed with tap water and dried, and then the specular reflectance of the portion was measured. As a method for measuring the specular reflectance, a spectrophotometer MCPD-100 (manufactured by Otsuka Electronics Co., Ltd.) was used, and the specular reflectance was measured according to the angle defined in Japanese Industrial Standard (JIS). That is, as shown in FIG. 2, the surface of the mirror 300 to be measured was irradiated with light from the light source 400 at an incident angle of 45 °, and the reflected light was measured by the light receiver 500. The specular reflectivity was calculated by setting the specular reflectivity of a new mirror of the same type as 100%. In addition, mirrors A and B both have a size of 30 cm wide and 45 cm long, which has been used for about 5 to 6 years in a rented studio apartment.

(Comparative Examples 1-5)
As shown in FIG. 7, acetic acid only (Comparative Example 1), citric acid only (Comparative Example 2), bamboo vinegar liquid only (Comparative Example 3), wood vinegar liquid only (Comparative Example 4), and 100 ml of wood vinegar liquid The cleaning effect on mirror A was confirmed under the same conditions as in the example except that 30 g of citric acid was mixed and stirred (Comparative Example 5).

  As a result, as shown in FIG. 7, the surface reflectances of Comparative Examples 1 to 5 when the surface was rubbed for 30 seconds were all about 60%, and a scaly white stain remained clearly even visually. I understand that. Moreover, even when polished for 60 seconds, the surface reflectance remains around 70%, and white stains are still conspicuous.

  On the other hand, in Examples 1 to 14, as shown in FIGS. 3 to 6, the surface reflectance when the surface was rubbed for 30 seconds greatly exceeded the comparative example, and scaly white stains were observed. Almost inconspicuous. In particular, the surface reflectances in Examples 2 to 5 and Examples 9 to 12 in which the amount of citric acid is 10 g to 25 g are increased to about 90%. Furthermore, when the surface was carefully polished for 60 seconds, the surface reflectance reached 95 to 98%, which was almost the same as the surface reflectance of a new mirror.

  Therefore, as can be seen from these examples, even when the glass polish according to the present invention comprising bamboo vinegar and citric acid is used, even a silica compound firmly fixed on the surface can be easily removed. . In addition, as shown in FIG. 3 to FIG. 6, the surface reflectance when the polishing time was 15 seconds was shown. However, about 15 seconds is still insufficient, and it is necessary to rub the surface for at least about 30 seconds. It has been found that if it is polished for at least 60 seconds, it will be sufficiently clean. Moreover, in Comparative Example 5 in which 30 g of citric acid was mixed and stirred in 100 ml of wood vinegar, the removal effect was low, and it was also found that wood vinegar does not provide a sufficient removal effect like bamboo vinegar.

  In addition, all the experiments according to Examples 1 to 14 were performed with bare hands, and after the experiment was completed, the hand was washed with tap water. I couldn't. Therefore, the glass polishing agent 100 according to the present invention has a very low possibility of adversely affecting the human body, and is far more than other commercially available cleaning agents, such as chlorine-based powerful cleaning agents for toilet cleaning. It turned out to be safe. Furthermore, it was also found that a mirror from which dirt was removed with the glass polishing agent of the present invention lasted longer than a mirror that was cleaned to the same extent by polishing with an abrasive alone. As a result of using the two mirrors after removing the dirt under approximately the same conditions for about one year, the mirror from which the dirt was removed with the glass polishing agent of the present invention had white dirt (silica compound) compared to the other. It was difficult to adhere.

Next, the Example and comparative example at the time of using the glass polish 100 which concerns on this invention as a rust remover are demonstrated.
(Examples 15 to 21)
As shown in FIG. 8, 5 g, 10 g, 15 g, 20 g, 25 g, 30 g, and 35 g of powdered citric acid (hydrate) are mixed and stirred for 100 ml of commercially available bamboo vinegar solution, respectively. A sample (rust remover) was prepared. Then, using these seven kinds of samples, confirmation experiments were conducted on the rust removal effect of five-dimension nails (JIS standard number NZ150, length 150 mm, thickness 5.2 mm) in which red rust was generated.

  As an experimental method, a plurality of the 5 inch nails having red rust on the surface are prepared in advance, and at least two or more 5 inch nails are immersed in each container storing the sample for 30 minutes and 1 hour. The surface was thoroughly rubbed with a finger to remove rust, and then rinsed with running water to wipe off moisture, and the residual state of rust was visually confirmed. And, the state where almost no rust remains, that is, the state where almost no rust can be visually confirmed is `` best '', the state where a little rust remains is `` good '', the state where rust is conspicuous, that is, can be clearly confirmed visually. It was recognized as “bad”.

(Comparative Examples 6 to 10)
As shown in FIG. 9, only acetic acid (Comparative Example 6), citric acid only (Comparative Example 7), bamboo vinegar liquid only (Comparative Example 8), wood vinegar liquid only (Comparative Example 9), and 100 ml of wood vinegar liquid The rust removal effect with respect to the said 5 inch nail was confirmed on the same conditions as an Example except having used the liquid (comparative example 10) which mixed and stirred the citric acid 30g.

  As a result, as shown in FIG. 9, in Comparative Examples 5 to 10, regardless of the immersion time, all remained to the extent that rust was conspicuous, and a sufficient rust removal effect was not obtained. On the other hand, in the case of Examples 15-21, when it was immersed for 30 minutes as shown in FIG. 8, rust fell and all remained. Further, when immersed for 1 hour, the rust removal effect was further enhanced, and rust was hardly confirmed. In particular, in Examples 16 to 19 in which the blending amount of citric acid was 10 to 25 g, it was the best state in which almost no rust remained.

  Therefore, as can be seen from these examples, the rust generated on the surface of the metal product can be easily removed by using the rust remover according to the present invention consisting of bamboo vinegar and citric acid. In the case of a large metal product that cannot be immersed in a liquid rust remover as in this embodiment, for example, in the case of a metal product such as scissors or a kettle or around a stainless steel sink in a kitchen, as shown in FIG. If the rust remover is put in the spray container 200 and sprayed on the surface of the metal product and rubbed with a metal scrubber, the surface rust can be easily removed.
