Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of cleaning a drain pipe. Specifically, the present invention relates to a method for simply and efficiently cleaning drain pipes in kitchens, bathrooms, washrooms, toilets, washing machine areas, etc.

[Conventional technology]

Drainage pipes often become clogged with oil and other dirt contained in the wastewater, which accumulates and forms scales and build-up, causing foul odors and blockages. Conventionally, methods for cleaning drain pipes have mostly used powder-type detergents that are sprinkled directly into the pipes, or liquid-type detergents that are poured directly into the pipes. However, these powder and liquid type detergents are not retained on the inner wall surface of the drain pipe and flow out before they can exert their cleaning effect, so the percentage of effective use is small and the sufficient effect cannot be achieved. . Particularly in recent years, many drainage pipes in kitchens, washrooms, etc. are vertical, and this drawback has become a problem.

[Problem that the invention seeks to solve]

The object of the present invention is to provide a method for simply and efficiently decomposing, removing and cleaning dirt or slimy particles that stick to the inner walls of drainage pipes and cause pipe odors and clogging.

[Means for solving problems]

In order to solve this objective, the inventors of the present invention conducted extensive research and found that if pre-foamed detergent is injected deep into the pipe, the injected foam will move upwards from the injection point and quickly move inside the pipe. It was found that it swells and stabilizes. The present invention is based on this knowledge, and is an aerosol can filled with foaming detergent for cleaning drain pipes in kitchens, bathrooms, washrooms, etc., and a long nozzle is connected to the spout of the aerosol can. The gist of the present invention is a method for cleaning a drain pipe, which is characterized by using a drain pipe, inserting the long nozzle deep into the discharge port, and spraying.

Hereinafter, the present invention will be described in detail. As shown in the accompanying drawings, the present invention uses an aerosol can with a long nozzle filled with a foaming detergent, and passes the pre-foamed detergent through the long nozzle into a pipe. Spray directly onto the inner wall of the area. That is, in the attached drawings, (1) shows an aerosol can, (2) shows a long nozzle attached to the spout of the aerosol can, and (3) shows a drainage pipe, but the tip of the long nozzle (2) extends into the pipe. Once inserted, press the spray button on the aerosol can and the force of the aerosol will spray deeper into the can.

Such aerosol cans with long nozzles are conventionally known and are not particularly limited, but include:
The long nozzle usually has a diameter of about 0.5 to 1.0111 mm and a length of about 150 to 200 mm.

The longer the length, the more preferable it is, but if it is too long, it will be inconvenient to handle, and it will also be limited by the ejection power of the aerosol. Foaming aerosol detergents are not particularly limited, but those that generate a large amount of foam (stable foam) are preferably used. Examples of foaming aerosol detergents include surfactants, builders, amines, organic solvents, water, It contains a propellant such as LPG.

In addition, as detergent ingredients, oil-soluble solvents such as propylene glycol monobutyl ether and limonene are also blended to break down oil stains stuck inside the pipes, and a small amount of fragrance is blended to leave a refreshing scent after cleaning. .

〔Effect of the invention〕

If the spray is continued into the pipe as described above, the foamed foam will swell upward from the sprayed area and fill the pipe. If left in this state for a while, the bubbles will gradually descend. During this time, dirt stuck to the inner wall of the pipe is dissolved and removed.

Next, if you rinse the inside of the pipe by running water, the bubbles will move deeper into the pipe and the cleaning will be completed cleanly. Yellowing, slimy, odor, oil stains, etc. on the inner circumference of the drain pipe will be easily removed, and the pipe will be completely cleaned. can be prevented from clogging.

Next, the present invention will be explained in more detail with reference to Examples. In the Examples, all "%" indicates "% by weight".

Example 1 1) IJ monene 2.00%, propylene glycol monobutyl ether 2.00%, sodium metasilicate 2.
00%, phosphoryoxyethylene nonylphenyl ether (

, lemon fragrance (Ogawa Fragrance Co., Ltd., 6E-29843
) 0.2%, monoethanolamine 1.00%, ammonia (025%) 1.00% and water (balance) and 90% of the intermediate solution obtained by mixing LPG (3.8Ky
/cl) was filled into an aerosol can (AE330, manufactured by Toyo Seikan Co., Ltd.). (Contents: 315 g per can) Pulp with steel balls was used, and a long nozzle with an inner diameter of 0.77 mm and a length of 185 nm was attached to the aerosol can. The nozzle of this aerosol can was inserted all the way into a kitchen drain vibro (caliber: 5 liters) and sprayed until the pipe was filled with bubbles (about 8 seconds). The pipe was left as it was for about 5 minutes to allow the foamed detergent to react with the dirt stuck to the inner wall of the pipe. After that, when I washed the inner wall surface of the pipe with an appropriate amount of water, the unpleasant odor was gone, the smell was refreshing, and most of the dirt had been removed. On the other hand, for comparison, commercially available pipe cleaners are powder type (based on sodium metasilicate, sodium percarbonate, or sulfamic acid, mixed with a surfactant) and liquid type (based on caustic soda or sodium hypochlorite). When we sprinkled or poured detergents into the drain pipes of a similarly dirty kitchen, we found that these detergents did not adhere to the inner walls of the pipes much; I poured water and washed it away, but the smell was not completely removed and the dirt remained.
