A self-adhesive material for a wood board is described. The self-adhesive material is formed of polyolefin film having a melt index is &#x2264;4 g/10 min (measured at 190&#xb0; C. and 2.16 kg), and the polyolefin film contains reactive groups with &#x2014;OH groups of the wood for forming self-adhesive properties. Further, a wood board in which the self-adhesive material is used as a coating and/or as a glue-line material is described.

Self-adhesive material for wood board and wood board

The invention relates to a use of a reversible molten salt for separating hydrocarbons, such as crude bitumen and/or heavy crude oil, from material comprising mineral solids. The invention relates also to a method comprising at least the steps of: (a) bringing a liquid phase comprising a reversible molten salt, preferably a reversible ionic liquid, in a contact with mineral solids comprising hydrocarbons and extracting hydrocarbons to the liquid phase from the mineral solids; (b) separating the mineral solids phase from the liquid phase, which comprises molten salt and hydrocarbons; (c) separating hydrocarbons from the liquid phase comprising molten salt; and (d) recycling the liquid phase comprising molten salt to step (a).

Method for separating hydrocarbons and use of molten salt

The invention relates to a coating for a wood board. In accordance with the invention, the coating is formed of at least three layers, which are the first () layer formed of a film containing polyolefin and a coupling agent which is reactive with &#x2014;OH groups of the wood for forming self-adhesive properties, second () layer selected from the group signaling layer and decorative layer and third () layer formed of a film containing polyolefin and the coupling agent which is re-active with &#x2014;OH groups of the wood for forming self-adhesive properties, and the second layer is arranged between the first and third layers, and the layers are joined together by means of the coupling agent. Further, the invention relates to a wood board () which has been coated by said coating.
