Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slime peeling remover that can be advantageously used for peeling and removing slime generated on a solid surface such as a drain pipe, and a slime peel removing method using the slime peel remover. It is.

  It is easy for slime to occur on the inner surfaces of drainage pipes around water such as kitchens, bathrooms, and washrooms. Slimming not only impairs aesthetics but also causes off-flavors. For this reason, it is necessary to peel and remove the slime generated in the drain pipe.

  The slime is a viscous substance containing bacteria that have grown from food residues and human waste as nutrients, and bacterial discharge. Bacteria (particularly Pseudomonas aeruginosa) effluents include polysaccharides such as calcium alginate, proteins and the like. In order to peel and remove such slime from the drain pipe, it is necessary to decompose proteins or polysaccharides contained in the slime.

In Patent Document 1, as a slime removing agent having excellent proteolytic ability, an alkali metal hypochlorite is used as a main base material, and at least selected from N-acyl sarcosine salts, trialkylamine oxides, or alkyl sulfonates. A slime remover containing a type of surfactant, an alkali metal hydroxide salt, and water is disclosed.
JP 2003-55698 A

The slime removing agent containing an alkali metal hypochlorite disclosed in Patent Document 1 as an active ingredient has an immediate effect on peeling peeling of the slime, but has a problem that its removal effect is short.
An object of the present invention is to provide a slime peeling remover capable of maintaining the slime removing effect over a long period of time.

  The present inventor has found that when a weakly alkaline magnesium aqueous solution is brought into contact with a slime generated on a solid surface such as a drain pipe, the slime is easily peeled off from the solid surface. And if the granular material containing magnesium hydroxide or magnesium oxide is installed at the upstream side of the opening of the drainage pipe where the slime has occurred or the surrounding area, or the location of the slime in the drainage pipe, In a state where magnesium hydroxide and / or magnesium oxide is dissolved little by little in the water flowing through the water, the weakly alkaline magnesium aqueous solution can be brought into contact with the slime over a long period of time, and the internal surface of the drainage pipe is peeled off and removed. The present invention was completed by confirming that it can be maintained over a long period of time. It should be noted that when the weakly alkaline magnesium aqueous solution is brought into contact with the slime, the slime is easily peeled off from the solid surface because the calcium ions of calcium alginate, one of the viscous components of the slime, are replaced with magnesium ions. This is probably because alginic acid is dissolved in water.

  Therefore, the present invention includes bacteria and bacteria formed on a solid surface, including particulate matter containing 50% by mass or more of magnesium hydroxide and / or magnesium oxide and having an average particle diameter in the range of 0.1 to 50 mm.
