Description
本発明は、エアコン洗浄に適したエアコン用洗浄原液、洗浄液及び洗浄方法に関するものである。 The present invention relates to an air conditioner cleaning stock solution, a cleaning liquid, and a cleaning method suitable for cleaning an air conditioner.
エアコン洗浄の作業では、界面活性剤や化学物質を配合した洗浄液、苛性ソーダ配合の強アルカリ性の洗浄液が用いられることがある。
このような洗浄液には、例えば界面活性剤や化学物質、苛性ソーダ等の劇物が含有されており、被洗浄物、作業者及びこの洗浄したエアコンが設置されている環境に悪影響が生じることがある。
When cleaning air conditioners, cleaning solutions containing surfactants and chemicals, and strong alkaline cleaning solutions containing caustic soda are sometimes used.
Such cleaning solutions contain harmful substances such as surfactants, chemicals, and caustic soda, which can have a negative impact on the objects being cleaned, workers, and the environment in which the cleaned air conditioner is installed. .
すなわち、界面活性剤は、皮膚から吸収され、肝臓で分解されずに体内に蓄積される。アトピー症状が出たり、アレルギーの原因になるなど、人体に悪影響を及ぼすこともある。
また、天然由来の界面活性剤は、石けんなどに使われている界面活性剤である。微生物の働きによって、最終的には水と炭酸ガスに分解されて自然に帰ることができる。しかし、合成洗剤などに使われている石油系の界面活性剤は、分解されるまでに非常に長い時間がかかり、なかには完全に分解されずに生態系に悪影響を及ぼす成分も含まれていることがある。
That is, surfactants are absorbed through the skin and accumulate in the body without being broken down by the liver. It can also have negative effects on the human body, such as causing atopic dermatitis and allergies.
Naturally derived surfactants are those used in soaps and the like. Through the action of microorganisms, it is eventually decomposed into water and carbon dioxide and returned to nature. However, petroleum-based surfactants used in synthetic detergents take a very long time to decompose, and some of them may not be completely decomposed and may have a negative impact on the ecosystem. There is.
近年、このような劇物を含有しない洗浄液を用いてなくても、ウルトラファンバブル高圧洗浄機を用いることで高い洗浄効果を発揮する方法が知られている。
このような洗浄方法に用いる洗浄液は、ＮａＯＨ及びＫＯＨを主成分としており、界面活性剤も含有している。
In recent years, a method has been known that uses an ultrafan bubble high-pressure washer to achieve a high cleaning effect without using a cleaning liquid that does not contain such deleterious substances.
The cleaning liquid used in such a cleaning method has NaOH and KOH as main components, and also contains a surfactant.
しかしながら、このような洗浄液を、ウルトラファインバブル高圧洗浄に使うと、ウルトラファインバブルの影響で界面活性剤の発泡が強くなるため、通常の高圧洗浄機使用時と比べて極端に泡立ちが激しく、このクリーム状の泡の影響で洗浄が困難である。 However, when such a cleaning solution is used for ultra-fine bubble high-pressure cleaning, the foaming of the surfactant becomes stronger due to the influence of the ultra-fine bubbles, so the foaming is extremely intense compared to when using a normal high-pressure washer. Difficult to clean due to creamy foam.
このことにより以下３つの問題点が発生する。
泡立ちが激しいため、洗浄後のすすぎに使う水の量が約２０％増加し、また目視で洗浄効果が確認しにくいため作業における効率が低下する。
流れにくいクリーム状の泡の影響でアルミフィンに接触する時間が増えることで、ＮａＯＨ及びＫＯＨがアルミフィンを腐食するリスクがある。
大量の泡が跳ね返ることで周辺に飛び散り、ＮａＯＨ及びＫＯＨの影響で汚染するだけでなく、エアコン付近のアルミサッシなどの素材を腐食するなどのリスクが高い。
This causes the following three problems.
Because of the strong foaming, the amount of water used for rinsing after cleaning increases by about 20%, and the efficiency of work decreases because it is difficult to visually confirm the cleaning effect.
There is a risk that NaOH and KOH will corrode the aluminum fins due to the increased contact time with the aluminum fins due to the influence of the creamy foam that does not flow easily.
A large amount of bubbles rebounds and scatters around the area, which not only causes contamination due to the effects of NaOH and KOH, but also poses a high risk of corroding materials such as aluminum sashes near the air conditioner.
上述した問題を解決するため下記洗浄液を新たに開発。これを用いたエアコン洗浄方法を確立した。
本発明は、このようなエアコン洗浄作業に用いられるエアコン用洗浄液の現状に鑑みなされたもので、エアコンの部品であるアルミ素材を腐食することなく、且つ高い洗浄効果を有し、安全、安心、無害なエアコン用洗浄原液、洗浄液及び洗浄方法を提供することを目的とする。
In order to solve the above-mentioned problems, we have newly developed the following cleaning liquid. We established an air conditioner cleaning method using this.
The present invention was developed in view of the current state of the air conditioner cleaning liquid used in such air conditioner cleaning work, and it does not corrode the aluminum material that is the part of the air conditioner, has a high cleaning effect, and is safe, secure, and safe.

以下、本発明の実施形態に係るエアコン用洗剤及びエアコン洗浄方法を説明する。
一般的なエアコン洗浄液（ＮａＯＨ及びＫＯＨを主成分とし界面活性剤を含有したもの）を改良し、界面活性剤不使用のエアコン洗浄液である。
Hereinafter, an air conditioner detergent and an air conditioner cleaning method according to an embodiment of the present invention will be described.
This is an improved version of the general air conditioner cleaning liquid (which contains NaOH and KOH as main components and a surfactant), and is a surfactant-free air conditioner cleaning liquid.
本実施例のエアコン用洗浄原液は、
界面活性剤を含まないエアコン用洗浄原液であって、
含有量０．３～０．９重量％の水酸化カリウムと、
含有量３～１９．９重量％の２-アミノエタノールと、
含有量７～１５重量％のケイ酸塩と、
含有量１～１５重量％のグルコン酸ナトリウムと、
水と、を含む。
また、本実施例のエアコン用洗浄原液は、キレート剤を含有している。
本実施例のエアコン用洗浄原液は、水酸化ナトリウムを含有しておらず、ｐＨ１３～１４のアルカリ性である。
また、本実施例のエアコン用洗浄原液の上記水は、水道水、もしくは蒸留水である。
The cleaning solution for air conditioners in this example is as follows:
A cleaning solution for air conditioners that does not contain surfactants,
Potassium hydroxide with a content of 0.3 to 0.9% by weight,
2-aminoethanol with a content of 3 to 19.9% by weight,
silicate with a content of 7 to 15% by weight,
Sodium gluconate with a content of 1 to 15% by weight,
including water.
Further, the air conditioner cleaning stock solution of this example contains a chelating agent.
The air conditioner cleaning stock solution of this example does not contain sodium hydroxide and is alkaline with a pH of 13 to 14.
Further, the water in the air conditioner cleaning stock solution of this embodiment is tap water or distilled water.
本実施例のエアコン用洗浄液は、界面活性剤を含まないエアコン用洗浄原液と、
エアコン用洗浄原液を５～２０倍に希釈する水と
を含み、
前記エアコン用洗浄原液は、
含有量０．３～０．９重量％の水酸化カリウムと、
含有量３～１９．９重量％の２-アミノエタノールと、
含有量７～１５重量％のケイ酸塩と、
含有量１～１５％のグルコン酸ナトリウムと、
水と、を含む。
The air conditioner cleaning liquid of this example is an air conditioner cleaning stock solution that does not contain a surfactant,
Contains water to dilute the air conditioner cleaning solution 5 to 20 times,
The cleaning solution for air conditioners is
Potassium hydroxide with a content of 0.3 to 0.9% by weight,
2-aminoethanol with a content of 3 to 19.9% by weight,
silicate with a content of 7 to 15% by weight,
Sodium gluconate with a content of 1 to 15%,
including water.
本実施形態のエアコン用洗浄液には下記特徴がある。
ウルトラファインバブルでも泡立たない様に界面活性剤（非イオン、陰イオン各界面活性剤）を不使用とする。通常の洗浄機では洗浄力低下につながるが、ウルトラファインバブルを使用した場合は洗浄力に影響はなく、逆に２０％～３０％すすぎに使う水の量が少なくなり、目視での洗浄効果の確認も容易となり作業効率が向上する。
The air conditioner cleaning liquid of this embodiment has the following characteristics.
No surfactants (nonionic or anionic surfactants) are used to prevent foaming even with ultra-fine bubbles. With normal washing machines, the cleaning power decreases, but when using Ultra Fine Bubbles, the cleaning power is not affected, and on the contrary, the amount of water used for rinsing is reduced by 20% to 30%, which reduces the visual cleaning effect. Confirmation becomes easier and work efficiency improves.
また、ＮａＯＨを非使用でありＫＯＨの含有を1％未（例えば０．９％）とすることにより、エアコン本体のアルミフィン部分の腐食を抑え腐食によるトラブルを低減できる。 Furthermore, by not using NaOH and containing KOH at less than 1% (for example, 0.9%), corrosion of the aluminum fin portion of the air conditioner body can be suppressed and troubles due to corrosion can be reduced.
さらに、アミノエタノール、ケイ酸塩を安定性上限まで含有を増やし（従来品の１．５倍）洗浄果を高めることにより、ＮａＯＨ及びＫＯＨを主成分とする従来の洗浄液と同様の洗浄効果を維持。 Furthermore, by increasing the content of aminoethanol and silicate to the upper limit of stability (1.5 times that of conventional products) and increasing the cleaning effect, it maintains the same cleaning effect as conventional cleaning liquids whose main ingredients are NaOH and KOH. .
本発明に至った経緯は以下である。
ＮａＯＨとＫＯＨには、強い洗浄力がある一方、アルミを腐食するリスクがあり、そのリスクを低減しつつも洗浄力を担保する必要があった。
The circumstances leading to the present invention are as follows.
While NaOH and KOH have strong cleaning power, there is a risk of corroding aluminum, so it was necessary to reduce that risk while ensuring cleaning power.
また、界面活性剤の働きの一部である汚れを素材から浮かし剥がす働きを無くすことは、洗浄力が低減するリスクがあったが、ウルトラファインバブルの分離作用でこれを補うこととした。 In addition, eliminating the ability of surfactants to lift and remove dirt from materials had the risk of reducing cleaning power, but we decided to compensate for this with the separation effect of ultra-fine bubbles.
以上のことから、ウルトラファンバブル高圧洗浄機を用いたエアコン洗浄において、本実施例のエアコン用洗浄原液を用いことで、泡立ちを抑さえ、アルミフィンや周辺に対する素材腐食のリスクを抑え尚且つ洗浄力を高めた洗浄が可能となった。 Based on the above, when cleaning an air conditioner using an ultra fan bubble high pressure washer, by using the air conditioner cleaning stock solution of this example, it is possible to suppress foaming, reduce the risk of material corrosion to the aluminum fins and surrounding areas, and clean. Cleaning with increased power is now possible.

FIG. 4 is a chart for explaining the effects of cleaning an object to be cleaned using the air conditioner cleaning stock solutions of Examples 1, 2, and 3, respectively.
Among the items shown in Figure 4, the "effect on materials" was applied in all of Examples 1 to 3 for 1 hour diluted solution and 20 times diluted solution for aluminum pieces, hydrophilic coating pieces, and aluminum foil pieces. No change in appearance was observed after immersion for 2 hours or 3 hours. Therefore, during the air conditioner cleaning work, there is no adverse effect on the parts made of each material of the air conditioner.

また、実施例２の原液は、１時間浸漬でアルミ箔片を全て溶解、実施例３の原液は１時間、２時間、３時間浸漬でアルミ箔片を一部溶解させた。このような原液での溶解度は、実施例２が高い（洗浄力が高い）。
Among the items shown in Figure 4, "cleaning power" was determined by the undiluted solutions of Examples 2 and 3, where the aluminum pieces were partially whitened when immersed in water for 1, 2, and 3 hours, and the hydrophilic coated pieces showed slight whitening after immersed in water for 3 hours. dissolve in
In addition, the stock solution of Example 2 completely dissolved the aluminum foil pieces by immersion for 1 hour, and the stock solution of Example 3 partially dissolved the aluminum foil pieces by immersion for 1 hour, 2 hours, and 3 hours. The solubility in such a stock solution is high in Example 2 (high detergency).

Regarding the items shown in FIG. 4, Example 1 has low detergency (solubility), but has no adverse effect on air conditioner parts in other items.
Example 2 has the highest detergency and has no adverse effect on air conditioner parts in all other respects.
Example 3 received somewhat lower evaluations in terms of crystallization and stability. In addition, the evaluation is somewhat lower than that of Example 2 in terms of safety, detergency, and cost.
実施例３は、結晶化が起こり、安全性が実施例２よりは低くなる。また、ケイ酸塩の配合量（上限）により、逆にアルカリ溶解度抑制が働き、洗浄力は実施例２に比べて低下する。洗浄力及び製品の安全性、素材への影響は実施例２が最適である。 In Example 3, crystallization occurs and safety is lower than in Example 2. In addition, depending on the amount (upper limit) of the silicate, the alkali solubility is suppressed, and the detergency is lower than that in Example 2. Example 2 is optimal in terms of cleaning power, product safety, and influence on materials.
