The invention is directed to a process for the continuous acetylation of wood elements. The process particularly combines a batchwise impregnation step, with a continuous reaction step. In order to realize this, a collection step is built-in, so as to allow batches of impregnated wood elements to be fed into a reactor in a continuous manner. Very high acetylation contents can be obtained, at a level that had not been achievable before in a continuous and non-catalyzed acetylation process.

A system for treating wood (30), comprising: —a treatment vessel (14) configured to receive at least one wood stack (4) for treatment, and —a stack holding system (2) for holding a wood stack (4), the stack holding system (2) comprising: —a frame (6), configured to support the wood stack (4); —a first element (8), connected to the frame (6) near an upper side of said frame (6), configured to exert a first, downward force on the wood stack (4); and —a second element (10), connected to the frame (6) near a lower side of said frame (6), configured to exert a second force on the wood stack (4) in a direction opposite said first force. The invention also comprises a method for treating wood, using a system for treating wood according to the invention.

Process for the treatment of plant tissue having a capillary system with active substances and/or dyestuffs, characterised in that a shaped piece containing openings and/or having grooves or knobs on its surface, the openings or surface structure of which are loaded with active substance and/or dyestuff, is applied to the plant tissue with the aid of a setting tool or setting device in such a way that no air penetrates into the capillary system.

A wood treatment device may include a container and a closure assembly. The container may include an elongate body with an open end and having an internal expanse for holding a wood-treatment agent in fluid communication with the open end. The closure assembly may be configured, when positioned at the container open end, to close at least partially the open end. The closure assembly may include a release unit having an inner face exposed to the internal expanse and an outer face facing away from the internal expanse. The release unit may be configured to impede passage of the wood-treatment agent through the release unit. In some examples, an adapter may extending distally of the container and have an exposed surface facing the container and defining an opening configured to allow a foot of a manipulation tool to be moved through the opening and pivoted laterally to engage the adapter.

This application relates to the technical field of building material processing, and more particularly, to a method for manufacturing a transparent heat-insulation building material based on waste wood. The method includes the following steps of: step S1, wood pretreatment, step S2, wood acetylation treatment, step S3, resin impregnating, and step S4, hot press molding to obtain a densified wood.
