Definitions

• the present invention relates to a process for the preparation of Garden furniture made of robinia wood, comprising a process step, in which the robinia wood is treated.
• Robinia wood is ideal for the production of Outdoor furniture, because it is harder, weatherproof and durable than most other woods.
• Rotimber is regarding its hardness, weather resistance and durability even to date in the outdoor area preferred teak superior.
• Robinie over teak has the advantage that robinia wood no Tropical wood is but a wood that can be grown in Europe. The Use of Robinienholz for garden furniture is thus not allowed the cutting down of the rainforest.
• the problem underlying the present invention is the Creating a method of the type mentioned, with which creates an attractive surface of Robinia wood.
• the robinia wood at least 30, preferably at least 60 hours is attenuated.
• the robinia wood between 60 and 90 hours, in particular about 80 hours is attenuated. It has been found that, depending on the strength of the to be damped Woods after about 80 hours on average the desired Color change both on the surface and in the interior of the Wood has taken place.
• the Robinia wood is steamed at a humidity of 100%.
• the robinia wood at the latest four weeks after the impact in particular At least two weeks after the impact is dampened. It has shown to be achieved by steaming Color change may then no longer be achieved If, after the impact waits too long, until with the Steaming the robinia wood is started.
• the robinia wood is dried after steaming.
• the robinia wood up to a wood moisture of 9% to 12%, preferably up to one Wood moisture is dried between 10% and 11%.
• Wood moisture is comparatively ideal for the further treatment of the Wood.
• the drying is about in a period between 10 and 25 days, especially in one Period of 15 to 20 days is performed.
• the robinia wood after steaming and before drying for a certain Time span is temporarily stored. During the interim storage It is possible to neutralize the wood, causing cracks in the wood be avoided.
• the robinia wood is mechanically processed after drying, in particular by Cutting and / or milling and / or drilling and / or grinding.
• the robinia wood after steaming, especially after drying mechanical processing surface finishing.
• This surface finishing for example, by a glaze be achieved.
• it may be a brown glaze act.
• the surface finishing also by a paint, especially achieved by a white paint become.
• the Surface finishing an introduction into a fungicide solution includes. Such incorporation into a fungicide solution can in particular before the connection of individual parts of the garden furniture done so that the joints are effectively protected.
• the Surface treatment a contribution to a wood preservation solution includes.
• the introduction into the wood preservation solution can, for example be realized by diving.
• a primer is carried out, in particular by immersion in a corresponding primer solution.
• a top coat on the primer is, in particular by spraying.
• the coating lacquer Color pigments include, in particular brown color pigments.
• At least one intermediate coat is applied, in particular by spraying.
• two intermediate coatings can be applied, wherein drying between these two intermediate coatings can take place.
• a top coat is applied, in particular by spraying.
• the topcoat white is.
• the primer, the at least one Intermediate coating and the topcoat can thus be a coating, In particular, a white finish can be applied.
• the Paint can be made porous, because by the steaming the tannic acid can be largely removed. An open-pored Paint offers the user a much more pleasant Attack.
• the Robinie is taken in the months of September to May. After the impact, the Robinia tribes become planks cut.
• the Damping occurs at a temperature between 95 and 105 ° C a humidity of 100% instead.
• the Tailored planks can make steaming more or less long to last; to endure, to continue.
• For average board thicknesses from 23 mm to 45 mm is a meaningful damping duration between 60 hours and 90 Hours, where the average duration of the steaming process is about 80 hours.
• the steamed planks are stored before entering corresponding drying chambers to about 10% to 11% wood moisture be dried. This requires an average drying time from about 15 to 20 days.
• the wood is up to the Reaching the fiber saturation point at about 25% wood moisture at dried at a temperature of about 40 ° C. Then it will be further dried at a temperature of about 55 ° C.
• planks After drying, the planks become so-called scantlings cut for legs, armrests and the like of Outdoor furniture can be used.
• a machining of the edges by milling and / or Drilling and / or grinding and the like.
• the parts are at least partially with each other connected.
• the partially interconnected Parts dipped in a wood preservative solution.
• the parts will be on it then dried and ground for at least 12 hours.
• the parts are immersed in a primer, After removal from the primer dried for 12 hours and ground.
• the coating varnish can in particular Have color pigments, in particular brown color pigments.
• the overlay paint can be 10% brown color pigments exhibit.
• the Garden furniture After the above surface treatment, the Garden furniture final assembled.
• fittings can be made V2A steel can be used so that the wood does not pass through Fittings is attacked.
• a white paint the partially interconnected parts immersed in a primer, 12 Hours dried and sanded. After that, the Parts are sprayed with an intermediate coat, 12 hours dried and sanded. After that, the Parts are sprayed a second time with the intermediate coat, Be dried and ground for 12 hours. it can connect to the thus treated parts a topcoat, In particular, a white topcoat be sprayed.
