  The invention refers to absorbent structures for use in an absorbent article, the absorbent structure comprising a water absorbing material. The water absorbing material is obtainable by a process comprising the steps of bringing particles of a non surface-crosslinked water-absorbing polymer in contact with at least one post-crosslinker, at least one water-insoluble metal phosphate, and at least one further ingredient. The at least one ingredient is selected from at least one Nitrogen-containing water-soluble polymer, and at least one hydrophobic polymer. The particles are heat-treated at a temperature in the range from 120°C to 300 °C.

  本发明涉及用于吸水制品的吸水结构，该吸水结构包括吸水材料。该吸水材料可通过一种工艺获得，该工艺包括以下步骤：使非表面交联吸水聚合物颗粒与至少一种后交联剂、至少一种不溶于水的金属磷酸盐和至少一种其他成分接触。至少一种成分选自至少一种含氮水溶性聚合物和至少一种疏水性聚合物。颗粒在 120°C 至 300°C 的温度范围内进行热处理。

  Painting in commercial, residential, and retail environments requires extreme care to avoid paint being deposited where it is not required. Drop cloths are commonly used to protect a floor or furniture during the painting process. However, these are generally simply plastic sheets to provide a barrier to the liquid paint and nothing more. Accordingly, it would be advantageous to provide a drop sheet or tarp that supports a liquid material drying process such as by dehydration, coagulate, etc. or form solid materials thereby reducing the instances of subsequent paint transfer from the drop sheet or tarp directly or indirectly to other surfaces and / or objects. It would also be advantageous to drop sheet or tarp that provides a non-slip surface which prevents the drop sheet from sliding around and remains well in place without additional weights, tape, etc.

  在商业、住宅和零售环境中进行油漆涂刷时需要格外小心，以避免油漆沉积在不需要的地方。在油漆过程中，通常使用遮盖布来保护地板或家具。然而，这些通常只是用来阻挡液体油漆的塑料布，仅此而已。因此，提供一种能够支持液体材料干燥过程（如脱水、凝固等）或形成固体材料的遮盖布或防水布将是非常有利的，从而减少随后油漆从遮盖布或防水布直接或间接转移到其他表面和/或物体上的情况。同样有利的是，遮盖板或防水布应具有防滑表面，以防止遮盖板滑动，并在没有额外重量、胶带等的情况下保持稳定。
