Abstract: The invention relates to chemically resistant structures that float on top of a liquid to reduce the level of evaporation from the liquid. The liquid could be in a small container or vat, or in a larger pool, pond, or reservoir. The structure is preferably a foamed material of a polyamide or fluoropolymer, or may be a hollow or foamed structure having a polyamide or fluoropolymer outer layer. The structures covering the liquid may consist of a single structure or two or more discrete structures that partially or fully cover the surface of a liquid. The covering is especially useful where the fluid contains toxic, reactive or corrosive substances. One preferred structure is a polyvinylidene fluoride foam structure (such as a KYNAR from Arkema Inc) at about 0.1-36 inches in length/diameter.

Abstract translation: 本发明涉及浮在液体顶部以降低液体蒸发水平的耐化学腐蚀结构。 液体可以在一个小容器或桶，或者在一个较大的池，池塘或水库。 该结构优选为聚酰胺或氟聚合物的发泡材料，或者可以是具有聚酰胺或氟聚合物外层的中空或发泡结构。 覆盖液体的结构可以由部分或完全覆盖液体表面的单一结构或两个或更多个离散结构组成。 当流体含有有毒，反应性或腐蚀性物质时，覆盖物尤其有用。 一个优选的结构是长度为约0.1-36英寸的聚偏二氟乙烯泡沫结构（例如来自Arkema Inc的KYNAR）。
