した湿潤剤なるものを塗布していた。2. Description of the Related Art Conventionally, for example, when asbestos is peeled off, as a means for preventing the dust from scattering, a wetting agent to which water or a surfactant is added in order to promote internal penetration is used. Had been applied.

【発明が解決しようとする課題】そして、これらの塗布

して大量に塗布していた。These coatings have been applied in large quantities with the viscosity of the liquid itself reduced as much as possible in order to increase the permeability.
【０００４】しかし、アスベストは自身のもつ吸水能力
の為に、塗布した直後瞬間的に吸水が始まるが、一定量
吸水するとその後は吸水しにくくなり、内部まで充分に
浸透しにくいという性質を有している。[0004] However, asbestos has its own water absorbing ability, so that water absorption starts instantly immediately after application, but after absorbing a certain amount of water, it has a property that it is difficult to absorb water thereafter, and it is difficult for the asbestos to sufficiently penetrate into the interior. ing.

共に表面の乾燥が進み、剥離除去する際の粉塵の飛散を
防止するという目的を充分に達成することはできない。[0005] Despite this, the actual situation is to apply the coating repeatedly four to five times to absorb more water. However, even if it is repeatedly applied many times, most of it falls down and does not sufficiently penetrate deep into the asbestos, but rather the surface progresses with the passage of time, preventing the scattering of dust when peeling and removing. The purpose cannot be fully achieved.

らないから、たれ落ちる液が多量になり、これが原因で
漏電等の事故を引き起こすことも多かった。[0006] Further, since the liquid used is extremely low in viscosity as described above, it is liable to drip. Therefore, the coating must be repeated many times to prevent drying of the surface and to supplement the coating amount. . In addition, since the liquid has to be applied many times, the amount of the liquid dripping off becomes large, which often causes an accident such as electric leakage.
【０００７】本発明は上記の点に鑑みなされたものであ

供せんとするものである。The present invention has been made in view of the above points, and it is an object of the present invention to effectively prevent the scattering of these dusts when peeling and removing asbestos and the like, and also to prevent various adverse effects caused by dripping. It is an object of the present invention to provide a method for preventing dust scattering.

【課題を解決するための手段】而して、本発明の要旨
は、保水剤と増粘剤を含む薬剤を処理対象物に塗布し、
所要の時間養生させた後該処理対象物を剥離除去するこ
とを特徴とする粉塵飛散防止方法にある。SUMMARY OF THE INVENTION Accordingly, the gist of the present invention is to apply a chemical containing a water retention agent and a thickener to an object to be treated,
A method for preventing dust scattering is characterized in that the object to be treated is peeled off after curing for a required time.
【０００９】また、上記保水剤、増粘剤を含む薬剤に浸
透剤を加えるようにしてもよく、更にまたこれらに発泡
剤及び／又は起泡剤、硬化剤を加えるようにしてもよ
い。Further, a penetrant may be added to the above-mentioned agent containing a water retention agent and a thickener, and a foaming agent and / or a foaming agent and a curing agent may be added to these.
【００１０】また、上記薬剤等を塗布した後、養生中
に、薬剤の粘性を利用して処理対象物の表面にシート類
を貼付し、表面からの乾燥を防ぐようにしてもよい。Further, after applying the above-mentioned chemicals or the like, sheets may be adhered to the surface of the object to be treated by utilizing the viscosity of the chemicals during curing to prevent drying from the surface.
【００１１】[0011]
【発明の実施の形態】以下、本発明の実施形態について
説明する。保水剤と増粘剤を含む薬剤を処理対象物であ
るアスベストに塗布する。この塗布は、ローラー、スプ
レー、刷毛、コテ等を用いて行う。Embodiments of the present invention will be described below. A chemical containing a water retention agent and a thickener is applied to asbestos to be treated. This application is performed using a roller, a spray, a brush, an iron, or the like.
【００１２】そして、その後所要の時間養生させた後、
該アスベストを剥離除去するものである。尚、養生に要
する時間は塗布する薬剤の量によって決定する。After curing for a required time,
The asbestos is peeled off. The time required for curing is determined by the amount of the applied medicine.
【００１３】このようにして行うと、保水剤と増粘剤を
含む薬剤の作用によりアスベストに深く浸透させること
ができる。したがって、アスベストの内部全体に充分に
薬剤を浸み込ませることができ、アスベストが剥離する
際にくずれても粉になって飛散することがない。また、
従来は１回の塗布量が６０〜１５０ｇ／ｍ2 と少なかっ
たが、本発明においては浸み込ませる量を増やすことが
できるから、１回に３００ｇ／ｍ2 以上塗布することが
可能となり、塗布回数も少なくて済む。[0013] By doing so, the asbestos can be deeply penetrated by the action of a chemical containing a water retention agent and a thickener. Therefore, the medicine can be sufficiently infiltrated into the entire inside of the asbestos, and even if the asbestos peels off and breaks, it does not become a powder and scatter. Also,
Conventionally, the amount of application at one time was as small as 60 to 150 g / m 2 , but in the present invention, the amount of infiltration can be increased, so that 300 g / m 2 or more can be applied at one time, The number of application times can be reduced.
【００１４】また、薬剤は湿潤性及び粘性を保ちながら
アスベストの内部迄浸透するから、アスベストを剥離す

止することができる。[0014] Further, since the drug penetrates into the asbestos while maintaining wettability and viscosity, it is possible to more effectively prevent the asbestos from scattering as powder when the asbestos is peeled off.
【００１５】また、薬剤は上記の如く粘性が高いから、
これを塗布したときに塗布部分から下にたれにくい。即

等の事故を起こす等の問題も生じない。[0015] Further, since the drug is highly viscous as described above,
When this is applied, it does not easily fall down from the applied portion. That is, the medicine is easily held on the application surface. Therefore, it is not necessary to apply the coating many times to prevent the drying or to supplement the coating amount as in the conventional case, and there is no problem such as an accident such as a leak due to a large amount of dripping liquid.

It has the effect of promoting the penetration of the drug throughout the asbestos interior. The effect can be further enhanced by further adding a penetrant, a foaming agent, a foaming agent, and a curing agent to the above-mentioned medicines alone or in combination.

ために粉になって飛散することがない。When a curing agent is added to the above-mentioned chemicals, the applied chemicals are hardened. Therefore, when asbestos or the like is peeled off using a tool such as kerosene, the asbestos does not fall apart and is removed as a lump. Can be. Therefore, the removing operation can be performed efficiently, and since it is hardened, it is not scattered as powder.

量を調節して塗布することが可能となる。According to the present invention, a chemical containing a water retention agent and a thickener can be surely and quickly penetrated into the entire inside of an object to be treated such as asbestos. Therefore, when an object to be treated such as asbestos is peeled off, even if it breaks, it does not scatter as powder. In addition, since the chemical has high permeability and can infiltrate a large amount of the chemical into the processing target at one time, the number of application times is small. In addition, it is possible to adjust the amount of application to apply.
