この発明は吹付はアスベストの除去方法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] This invention relates to a method for removing asbestos by spraying.
吹付はアスベストの有害性が大きな社会問題として注目
されているが、従来アスベスト除去方法としては次のよ
うな方法が知られている。Spraying is attracting attention as a major social problem due to the toxicity of asbestos, but the following methods are known as conventional asbestos removal methods.

等がそれである。(1) A method of using a powerful dust collector to simultaneously suck up the material cut by the worker and collecting it in a sealed container. (2) A method of spraying or injecting resin onto the asbestos to solidify it and removing it manually with a scraper ( 3) Methods include spraying high-pressure water to moisten and remove asbestos, and asbestos that has peeled off on the floor surface, gel it and capture it with a polymeric water-absorbing agent sprinkled on the floor surface, and mix it with cement to solidify and recover. .

が残ることは看過しえないものとされる。According to the above-mentioned conventional technology, it is said that the method described in (1) makes it possible to clean and ventilate the working room at once after the removal of asbestos]. 1) It is not reliable enough to expect a satisfactory effect in a wide range of construction sites since it only collects dust around the dust suction port.
(2) Removal methods that rely on human labor tactics require a great deal of labor from the workers involved in removing asbestos 21#, and detailed manual removal is impossible. Furthermore, although the method (3) is superior in terms of safety, workability, and F efficiency, it cannot be overlooked that there remains a problem in the dispersion of asbestos dust due to the impact when removing by spraying high-pressure water.

The purpose is to provide a method.

止するものである。That is, the present invention forms a continuous spray curtain by spraying pre-diluted polymer dispersion around the area where asbestos is to be removed by projecting high-pressure water, and captures and gels the dust that accompanies the peeling of asbestos. Alternatively, the spraying prevents asbestos from spreading through drying and solidification.

意義を存するものである。As described above, in the present invention, asbestos is peeled off and removed by spraying by spraying high-pressure water, but it has an important meaning in preventing asbestos dust from spreading due to the impact of the sprayed water.

散しないので二次公害発生の危険もない。Therefore, first, prior to the work, the asbestos removal area should be entirely surrounded by a polyethylene sheet, and the seams should be completely coated with Vj Water Nol to prevent any leakage of the sprayed water. Asbestos dust generated during high-pressure water injection in a closed enclosure is enveloped in a continuous spray curtain formed by a jet of diluted polymer dispersion. In other words, the asbestos dust that has been peeled off and scattered falls down due to the water being thrown, but the inner part of the asbestos becomes dust at the same time as it is thrown off, while the polymer dispersion that is continuously sprayed around the asbestos falls. The polymer dispersion that is caught and falls onto the ground envelops the dust, and some of it gels after falling, and some of it sticks to the floor or wall without scattering due to the dry solidification of the polymer dispersion. (Even when the polyethylene sheet is dismantled and collected after the work is completed, no dust is spread, so there is no risk of secondary pollution.

The seams of these sheets are glued with gum tape, and a waterproof coating is applied on top of it to prevent water leakage, so as to prevent moisture from leaking outside due to high-pressure water spraying and peeling. 0 Workers must wear masks while working. Asbestos $5) Engage in high-pressure water jet stripping without inhaling dust. Around the high-pressure water projection position, a pre-diluted polymer dispersion is sprayed with a sprayer in synchronization with the high-pressure water jetting and peeling.Continuous I!
' to form a fog curtain. Super absorbent resin is sprayed on the polyethylene sheet floor work area, and the hydrated asbestos removed by high-pressure water and the sprayed polymer dispersion immediately gel, and other dust is included in the polymer dispersion and some of it dries. At the same time, it adheres to the polyethylene sheet. In this way, the gelled, exfoliated asbestos and the dust contained in the polymer dispersion are collected within the polyethylene sheet in the work area, are deposited on the worker's clothing, and are never dispersed elsewhere.

のである。As described in 1, the present invention uses high-pressure water to spray a pre-diluted polymer dispersion onto the asbestos detachment, forming a continuous spray curtain to capture asbestos dust and prevent it from dispersing. Therefore, the removal and recovery of asbestos in the work area is ensured as gelled asbestos and polymer dispersion adhering dust without causing any damage outside the area, and the workability is extremely high and safety is assured. It is possible to demonstrate the thoroughness of pollution prevention without any anxiety.
