JP2000044987A - Solid fur remover - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a solid fur remover which can easily remove fur by only polishing with water by mixing and kneading a binder such as a rubber, a plastic, or an elastomer with an abrasive material and tourmaline and/or a detergent and molding the mixture. SOLUTION: At least one binder selected from among rubbers, plastics, and elastomers is mixed and kneaded with an abrasive material (e.g. silica rock or alumina), tourmaline having an average particle size of about 1.5 μm and a Mohs' hardness of 7-7.5 and/or a detergent (e.g. a sodium alkylbenzenesulfonate, a sodium salt of a fatty acid, or sodium fatty acid alcohol sulfonate), and if necessary a builder (e.g. sodium tripolyphosphate or bentonite) and amorphous silica. The resultant mixture is subjected to compression molding, injection molding, or extrusion and if necessary is vulcanized by heating to be solidified, thus giving a solid fur remover at least partly having convex or concave surfaces.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid scale remover for removing scale adhered to a water circulating appliance such as a kitchen appliance, a washroom, a bathroom and the like.

[0002]

2. Description of the Related Art Conventionally, commercially available products of this type of solid descaling agent include silicone rubber, natural rubber or vinyl chloride resin as a binder and silica,
It is manufactured by kneading an abrasive such as alumina and solidifying it by compression heating or heat extrusion. The thus obtained solid descaling agent is applied to a metal, enameled or porcelain tile device to which the scale is adhered, and is rubbed with water. It is a principle of removing scale using a polishing agent.

[0003]

The water scale contains a mixture of neutral fats and proteins which have become insoluble in water, and metal rust and dust mixed with the mixture and adhere to or adhere to the surface of the appliance. There are things. However, in the above-mentioned commercially available solid descaling agent, mainly, descaling is intended to be removed by abrasion, but a satisfactory removal performance is not necessarily obtained, and the purpose cannot be achieved unless used in combination with a detergent. There was a problem that there were many.

[0004]

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has made intensive studies, and as a result, has achieved the intended object by including tourmaline or a detergent having a surfactant effect. The present invention has led to the invention of a solid descaling agent capable of removing water. That is, the present invention relates to one or two of rubber, plastics or elastomer.
The gist is a solid descaling agent obtained by kneading and forming one or more binders with an abrasive such as silica stone and alumina, and tourmaline and / or a detergent.

[0005] Tourmaline is also called tourmaline and is a "polar crystalline" ore. When this ore comes in contact with water, the water is ionized and a surfactant effect is generated, which has the effect of facilitating the removal of water scale from the instrument surface. . Similarly, the detergent has the same surfactant effect as tourmaline. Therefore, the addition of tourmaline or a detergent improves the performance of removing scale. When tourmaline and detergent are added together, the surfactant effect is synergistic, resulting in even more pronounced removal performance.

[0006] Tourmaline has a Mohs' hardness of 7 to 7.5 and is useful as an abrasive. However, if the particles are too coarse, they may damage the counterpart equipment. A diameter of about 1.5 μm is desirable.
Silica stone has a Mohs hardness of 7 and is also preferred as an abrasive. on the other hand,
When a detergent is added together, amorphous silica having a large specific surface area is preferable in order to stably retain the surfactant used as the detergent in the solid molded product. It is desirable to use silica in a balance with a surfactant to be added.

As an abrasive, alumina or the like can be used in addition to silica stone. As the cleaning agent, a surfactant having a high cleaning effect can be used. For example, sodium alkylbenzene sulfonate, fatty acid Na, fatty acid alcohol sulfonate Na, or the like can be used, and used in combination with sodium tripolyphosphate, bentonite, or the like as a builder. It is desirable to do. These abrasives, tourmaline and / or detergents are uniformly kneaded with a binder, and are solidified by compression molding, injection molding, extrusion molding or the like, and, if necessary, by heating and vulcanizing.

As the binder, a polymer material such as rubber, plastics, and elastomer is used. As rubber, silicone rubber, natural rubber, SBR, NBR, E
There are PM, polyisoprene rubber and the like, all of which are vulcanized and cured. As the plastics, polyvinyl chloride or polyolefin resin can be used, and as the elastomer, a thermoplastic elastomer (T
PE) can be used, and specifically, a polystyrene-based thermoplastic elastomer such as polyolefin-based thermoplastic elastomer (TPO) and styrene-butadiene copolymer (SBS) can be used, and extrusion molding or injection molding can be used. To solidify. Of course, rubber, plastic, and elastomer may be mixed. The shape of the solid descaling agent may be cubic, but may be at least partially provided with a convex or concave curved surface.
