Sealing structure and sealing method for radon leakage of in-situ leaching uranium mining liquid collecting pool
The invention discloses a sealing structure and a sealing method for radon leakage of a liquid collecting pool for in-situ leaching uranium mining, pores are filled with single-component foaming polyurethane, and a compact radon-proof layer is formed by using a single-component polysulfide sealant with a low radon diffusion coefficient. And finally, acrylic ester paint which is good in radon-proof performance and has the same color as the environment is used as the second radon-proof layer, and the attractive effect is achieved. The single-component foaming polyurethane is used as a main framework for filling pores, the single-component polysulfide sealant is used as a main radon-proof material, the acrylate paint is used as a two-layer radon-proof and appearance-beautifying material, the radon sealing effect of the multi-layer material is excellent and reaches 78.2%, the weather resistance is good, and the service life is long. And meanwhile, the device can adapt to deformation of the color steel plate of the liquid collection pool in severe convection weather, has very high innovativeness and practical value, and has a good application prospect.
本发明公开一种用于地浸采铀集液池氡泄露的密封结构及密封方法，利用单组分发泡聚氨酯填充孔隙，利用氡扩散系数较低的单组分聚硫密封胶形成致密的防氡层。最后使用防氡性能较好的并且与环境色相同的丙烯酸酯漆作为第二层防氡层以及起到美观作用。以单组分发泡聚氨酯为填补孔隙的主要骨架，以单组分聚硫密封胶为主要防氡材料，丙烯酸酯漆为二层防氡及美化外观材料，多层材料氡密封效果优秀，达到了78.2％，且具有良好的耐候性，同时能够自适应集液池彩钢板在遭遇强对流天气时的形变，具有很强的创新性和实用价值，有良好的应用前景。
