Provided is a sheet containing a fluorine-containing copolymer. The arithmetic mean surface roughness Ra of at least one surface of the sheet is 5.0 μm or less, and the thickness of the sheet is 4 mm or less. Also provided is a method for producing a sheet containing a fluorine-containing copolymer, in which method a raw material containing a fluorine-containing copolymer is wound around a roll by a roll kneader equipped with at least one pair of rolls to form a sheet, the maximum temperature of the raw material when forming the sheet is 60°C or more, and the thickness of the obtained sheet is 4 mm or less.

The utility model discloses a kind of concrete blocks combined with microcapsule phase change material, it is related to concrete block technical field, the concrete block includes block main body, the top of the block main body is equidistantly provided with multiple positioning blocks, the bottom of the block main body is equidistantly provided with multiple positioning grooves, and positioning groove and positioning block are adapted between, and the block main body includes microcapsule phase change material main body.In the utility model, the microcapsule phase change material main body of block built-in, its kernel paraffin-fatty acid composite phase change material can be in 20~28 ℃ interval high-efficiency heat absorption and release, reduce indoor maximum temperature 2~5 ℃ in summer, reduce heat loss 15~25% in winter, realize building energy saving and indoor thermal comfort promotion, shell melamine-formaldehyde resin can completely block phase change material leakage, guarantee the stable temperature control life of block more than 15 years, avoid the functional attenuation caused by material loss of conventional phase change block.
