Description

[Detailed Description of the Invention] L! Yu (7)? J j'uL1 The present invention relates to an applicator for applying a mold removal liquid.

1171L'' Conventionally, mold removal liquids have been applied to objects to be treated by spraying or coating methods. However, when using the spray method, there is a large amount of scattering of the chemical solution, and there is a danger to the human body handling it due to the liquid nature and irritating nature of the chemical solution itself.Also, when the application area is large, it is difficult to apply and the work is difficult. There are bad drawbacks. The coating method does not have the disadvantages seen in the above-mentioned spray method, is considered to be effective, and has been conventionally used. However, when carrying out this application method, a brush made of natural or synthetic resin, a non-woven cloth, etc. are used for the application part, but when the viscosity of the chemical solution is low, the so-called liquid It tends to sag and is not very suitable.

Problem 1 to be Solved by Akira: The present inventors have been conducting extensive research on the above-mentioned applicator, especially the application part thereof, and in the process, they came up with the idea of using a sponge instead of the above-mentioned brush or the like.

However, polyurethane has conventionally been known as this type of sponge, and although the problem of liquid dripping has been solved when polyurethane is used, the sponge is easily discolored by ultraviolet rays,
Chemical deterioration and strength loss may occur, especially in the case of mold removal liquids whose active ingredients are sodium hypochlorite and sodium hydroxide, which have the disadvantage of poor chemical resistance, so they cannot be used as coating materials. admitted that it was not suitable for However, in subsequent research, it was discovered that when polyethylene open foam sponge was used as a component of the application product, the disadvantage of chemical deterioration seen in the above-mentioned polyurethane sponge was eliminated, and it became an extremely excellent applicator for mold removal liquid. I discovered that.

The present invention was completed based on this new knowledge.

Means for Solving the Problems, That is, the present invention is an applicator for applying a mold removal liquid, the applicator for mold removal being characterized in that the application part is composed of a polyethylene continuous foam sponge. related to.

The applicator of the present invention is based on the use of a polyethylene continuous foam sponge as the applicator, so that even if the applicator comes into contact with the mold removal solution, it does not become brittle or deteriorate.
It has excellent stability and durability, and can be used for a long period of time. Further, the applicator of the present invention has an appropriate elasticity in its application part, and is satisfactory in terms of usability and application workability.

In the present invention, as the polyethylene open foam sponge used as the application member, any of various known types can be used. A representative example thereof is "Opcel" manufactured by Sanwa Kako Co., Ltd. The sponge is JIS-
The apparent density according to 6767 is 0.027 to 0.0311
;l/C112 degree, tensile strength 0.94-1.6kO/
cm2, elongation 200-220%, tear strength approximately 1,
1 kg/am, and has an open cell rate of 97-99°8% according to ASTM-01940. In addition, it has excellent acid resistance, with dimensional change of less than about 1% even after drying when immersed in acidic and alkaline solutions such as 50% acetic acid, concentrated hydrochloric acid, 30% sulfuric acid, and 40% caustic soda solution for 24 hours. It has alkali resistance. Furthermore, this is mercury lamp irradiation (SHLlooUV, irradiation distance 10cm amount, tank temperature 40cm)
It has excellent climate resistance, with no color change observed even after 96 hours (±5°C), and is particularly suitable for the present invention.

Among the above sponges, those with a higher apparent density are relatively stiff and have excellent application workability, while those with a lower apparent density have good absorption and release properties for chemical solutions, and It has the advantage that it is easily absorbed by the sponge and distributed throughout the body, and moreover, it is easily transferred to the object to be treated by coating.

Of course, the present invention is not limited to the above, and other open polyethylene foam sponges having similar characteristics can also be used.

The applicator in the applicator may be composed of only a single layer of the above-mentioned continuous foamed polyethylene sponge; for example, the continuous foamed polyethylene sponge may have a multilayer structure consisting of two or more types of apparently different densities. It may have. Furthermore, the polyethylene continuous foam sponge may be used as an essential component and may have a multilayer structure with other olefin resin foams and the like. It is preferable that the resin foam that can have such a multilayer structure has approximately the same chemical resistance as the above-mentioned open polyethylene foam sponge. As an example, a single polyethylene foam sponge such as "Sambel Chikara" manufactured by Sanwa Kako Co., Ltd. can be exemplified. When used in combination, such a single foam sponge has the effect of reinforcing the weakness of the continuous foam sponge and ensuring sufficient transmission of force to the application portion during coating work. However, since the bubbles are not continuous, there is a risk that the supply and application properties of the chemical solution may be reduced. Therefore, when used in combination, it is necessary to provide suitable liquid introduction holes.

The above-mentioned multilayer can be formed according to a conventional method, such as a flame lamination method or a hot melt method.

The thickness of the above-mentioned application part is appropriately determined depending on the type of medicinal solution used, etc., and is not particularly limited.
Approximately 51 to 5
It is appropriate to set it to about 0 mm.

The applicator of the present invention may have any shape, structure, etc., as long as its applicator part is made of a polyethylene open foam sponge. For example, the above-mentioned applicator may basically be in the form of a bag, in which the tank containing the mold removal liquid is surrounded by the above-mentioned sponge layer. It can be put to practical use by absorbing it into a sponge layer.

Furthermore, a grip part may be attached to the bag to facilitate the application work of the liquid in the tank. According to this, there is no fear that the chemical solution will come into direct contact with the operator's fingers, etc. during the application work. It is hygienically safe.

Furthermore, the applicator of the present invention may include a suitable liquid extrusion container containing a mold removal liquid, an applicator section connected to the container, and a liquid guide means for supplying the liquid in the container to the applicator section. . One embodiment of such an applicator is shown in the accompanying drawings.

Example 1 Polyethylene extended foam sponge (
An applicator shown in FIG. 1 was prepared using Opcel LC300#2J (manufactured by Sanso Kako Co., Ltd.).

An alkaline mold remover having the following composition was filled as a chemical solution (5) into the container (1) of the applicator to obtain a mold remover applicator of the present invention.

Sodium hypochlorite (as available chlorine) 4.0% sodium hydroxide 1.0% by weight surfactant
1.0 weight 1% fragrance
Trace amount of ion-exchanged water Total: 10
Using the mold removal applicator obtained above,
When we applied the mold removal solution to the walls of the bathroom and investigated its workability, we found that there was no scattering of the chemical solution, which is seen when applying the same kind of mold removal agent in the form of a spray type, and the product has excellent workability when applied to large areas. The ease of use was very good.

In addition, the discoloration and dimensional changes of the coated area due to the mold removal solution were tested as follows. That is, a polyethylene continuous foam sponge (5 x 5 x 2 cm thick) to be used as the application part was immersed in the above mold removal chemical solution for one month at 25°C.
The state of the sponge was visually observed after 1 month and after 1 month. For comparison, instead of the polyethylene continuous foam sponge, polyurethane sponges (polyether type, "Color Form EC0J," manufactured by Bengami MTV Co., Ltd., and polyester type, "Moltobrene SC," manufactured by Bengami MTV Co., Ltd.) were each subjected to the same test.

As a result, the polyethylene continuous foam sponge showed no discoloration or dimensional change even after one month, whereas the polyurethane sponge already showed discoloration after one week and surface decomposition (chemical embrittlement). It was observed.
