ES2356586T3 - SEPARATION AGENT FOR WOOD APPLICATION. - Google Patents

Abstract

Agent (I) comprises a volatile substance and a separating substance, where the volatile substance is an alcoholic substance or alcoholic solution and the separating substance contains gasoline.

Description

The invention relates to the use of an agent according to the preamble of claim 1.

 Corresponding agents are used in the mechanization of wood as separating agents, to prevent the glue or protruding glue from sticking to the corresponding wood machining tools. For the application of these agents on the edge area of a wood or a piece 5 to be glued, these agents carry a more or less volatile substance and an active substance in the separation (separation agent), which dissolves in the substance volatile, and keeps the glue or glue away from the machine. The known separation agents are usually liquids, which are sprayed onto the intended area by means of spray nozzles. After application / spraying, the volatile substance is volatilized and leaves the separation substance itself behind. 10

 For this purpose, solutions of separation agents based on alcohol and white oil have been proposed in the past. A disadvantage of these separating agents is, among others, that in the case of the application of greater quantities of separating agent solutions, especially the edges of the wood frequently present oily residues. Therefore, the edges of the boards become slippery, which makes subsequent processing and handling clearly difficult. fifteen

 In addition, in the case of solutions of known separation agents it has been proven that the plates of the chain used for the transport of the boards in the wood processing, on which the boards rest, are damaged because the gummed ones swell of the plates of the chain that should prevent the tables that rest on them from slipping. This can lead to defects in woodworking.

 The invention is based on using an agent of the type mentioned at the beginning, which has been improved in terms of the aforementioned disadvantages.

 This mission is solved using an agent with the characteristics of claim 1. Advantageous embodiments of claim 1 are found in the dependent claims.

 According to the invention, according to a first embodiment, the separation substance is formed by means of a benzine and, according to a second embodiment, by means of an alcohol, preferably a trivalent alcohol such as glycerin. The tests have resulted in the fact that for a mass proportion of approximately 3% benzine / glycerin and a mass proportion of more than 96% alcohol - preferably ethanol - especially good results are achieved. In this way you can avoid oily residues on the edges of the wood.

 According to the first embodiment, aliphatic hydrocarbons are preferably provided as a separation substance, which can be presented in the form of compounds i-, n- or / and cyclo-aliphatic or mixtures thereof. As for the kinematic viscosity, the substances mentioned are of very low viscosity and are in the range of 1.0 to 2.0 mm2 / s at 25 ° C. Especially advantageous is a kinematic viscosity of approximately 1.6 mm2 / s at 25 ° C.

 The following 35 examples of execution have resulted in practice as particularly appropriate in terms of the mission to be resolved:

Execution example 1:

 Volatile substance

 Ethanol

 Mass ratio of volatile substance

 96-97%

 Separation substance

 Benzine, mixture of i-, n- and / or C10-C12

 Mass proportion of the separation substance

 3%

 Kinematic viscosity of the separation substance at 25 ° C

 1.6 - 1.7 mm2 / s

 The mass proportion of liquid substance may be variable in favor of the addition of additives soluble in the volatile substance, such as dyes. Without additives, the mass proportions of 97% ethanol and 3% benzine are preferable as a separating substance.

Execution Example 2:

 Volatile substance

 Ethanol

 Mass ratio of volatile substance

 96-97%

 Separation substance

 Trivalent alcohol, preferably glycerin

 Mass proportion of the separation substance

 3. 4%
