RAW MATERIAL POWDER FOR PIPING REPAIR GUNNING MATERIAL
To provide a raw material powder for a piping repair gunning material capable of being blown from a position away from piping when repairing the piping, having an excellent adhesion strength to the piping, and adhering easily to the piping.SOLUTION: The present invention is the raw material powder for a repair gunning material which is blown onto a damaged portion of the piping transporting a fluid to repair the piping. The raw material powder is mixed with water and a carrier gas and blown onto a repairing portion, and contains 18 to 65 mass% of an elastic resin, 15 to 65 mass% of portland cement and 2 to 34 mass% of aggregate with a particle diameter of 0.2 to 2 mm.SELECTED DRAWING: Figure 1
【課題】配管を補修する際に、配管から離れた位置から吹き付けることが可能であり、配管に対する接着強度に優れており、配管に対して付着しやすい配管吹付補修材用の原料粉末を提供する。【解決手段】流体の搬送する配管の破損部分に吹き付けて配管を補修する吹付補修材の原料粉末であって、当該原料粉末は、水と搬送気体と混合して補修箇所に対して吹き付けられるものであり、弾性樹脂１８〜６５質量％と、ポルトランドセメント１５〜６５質量％と、粒径が０.２〜２ｍｍの骨材２〜３４質量％とを含有する配管吹付補修材用の原料粉末である。【選択図】図１
