Definitions
- the invention relates to a wood treatment process in which lignocellulose-containing Materials are immersed in hot oil for a specified amount of time.
- a wood treatment process of the above type is the subject of DE 1 000 592. Das Impregnation process explained in this document is used to oil or oil as quickly as possible soak other impregnating agents to change the properties of the wood. By Use of high frequency is said to soak at a temperature of the oil bath of 200 ° C in a few minutes. Resistance can be achieved by such a procedure only increase compared to wood-destroying fungi, provided that the biocides corresponding to the oil Adds funds.
- a disadvantage of this type of heat treatment is however, in particular that at the required high temperatures (160-260 ° C) in a gas atmosphere due to the relatively poor heat transfer of gases and sensitivity of the entire remuneration process often an inhomogeneous remuneration with partial reduced resistance to wood-destroying fungi is achieved.
- Boiler pressure impregnation is particularly widespread as a wood preservation process.
- the Pressure impregnation has proven to be a very effective wood preservation process, however there are increasing concerns about the use of solutions containing heavy metals for reasons of environmental protection, because it cannot be excluded that these substances can be washed out of the wood over time and thereby into the ground and in reach the groundwater. There may be a hazard when performing the procedure of the persons entrusted with it and cause environmental damage from waste water.
- Wood preservation processes of the above type are recommended for wood products, that are exposed to the weather, for example in wooden buildings, fences or outdoors banks to be set up.
- Impregnation of tar oils practiced e.g. DE 4112643
- Heat treatments also for additional hardening of modified vegetable oils in impregnated wood e.g. WO 96/38275
- these procedures are only applicable to wood types that are easy to drink applicable; types of wood that are difficult to soak cannot be compensated.
- the invention is based on the problem of a wood treatment method with a preserving effect at the beginning to develop the type mentioned, which leads to the highest possible, uniform protective effect of the material over the entire cross-section, but not for health reasons or necessitates substances of concern for reasons of environmental protection, advantageous properties of the wood changed as little as possible and which with a the simplest possible system can be carried out.
- this problem is solved in that for controlled, thermal Converting the duration of the oil treatment to several hours and the temperature of the Oil bath is 180 ° C to 260 °.
- the method according to the invention is carried out in exactly the same way as for thermal treatment under protective gas to a preservative effect, without this for reasons of Environmentally harmful wood preservatives must be used. Because as a heat transfer medium however hot oil is used instead of protective gas, can be carried out during the implementation of the procedure work with relatively simple facilities, so that even smaller companies can apply the method according to the invention. Unlike other wood preservation processes, whose protective effect is based on the impregnation with various substances, can also use this process to process impregnable, lignocellulosic materials such as. Spruce, poplar or bamboo due to the thermal transformation over the whole Cross-section can be coated homogeneously since no substances are introduced into the material Need to become.
- the protective effect is achieved by thermal conversion of the lignocellulose-containing Caused substance, the oil serves as a heat exchanger and shields the to be remunerated Material before exposure to oxygen. Escaping gases prevent penetration of the oil during the thermal treatment, e.g. just a few millimeters of wood oil-soaked and can be planed off, making oil-free tempered wood products If necessary, easily soakable types of wood such as pine sapwood be impregnated by cooling the oil after the thermal treatment.
- the treatment according to the invention is very homogeneous in oil and additionally For increased resistance to wood-destroying fungi there is a high dimensional stability of the wood.
- the necessary heating of the oil is usually possible for woodworking companies without significant additional costs, since waste wood is often generated in such companies, which can be burned to generate the required heat.
- the heated oil can be pumped out at the end of the treatment, as a result of which the thermal energy stored in the oil can be transferred quickly to other reactor vessels with little energy loss.
- the high oil temperatures of 180-260 ° C. do not lead to any crack formation upon contact with moist products containing lignocellulose. For example, freshly sawn, large-sized spruce scantlings with the dimensions 100x100x1350 mm 3 were thermally converted in hot rapeseed oil over the entire cross-section without cracks in an oil bath.
- the method according to the invention has so far been tested in practice in the case of pine and spruce wood, with improved dimensional stability and increased resistance to wood-destroying fungi being found in laboratory tests. A few hours are usually sufficient for the treatment; however, the remuneration period depends on the material moisture and the dimensions and can take several days if the values are high. A treatment time of 4.5 hours on samples with the dimensions 50x25x15 mm 3 and an initial wood moisture of 6% was tested in practice and found to be sufficient.
- Fresh, untreated pine ( Pinus sylvestris L.) and spruce ( Picea abies L. Karst.) Were cut to the dimensions given in Table 1.
- the samples were heated with a wood moisture content of 6% at three temperatures (180 ° C, 200 ° C and 220 ° C) without pressure in an oil bath made of pressed, refined linseed oil with exclusion of oxygen. After reaching the desired temperature, the wood samples were immersed in the hot oil for 4.5 hours. The samples cooled in the oil bath for 15 minutes. Comparative samples were also treated in the drying cabinet at appropriate temperatures in an air atmosphere for 4.5 hours (no protection claim is made for the treatment in air).
- Mass change The mass increase WPG (Weight Percent Gain) of the oil-heat-treated samples was 50-70% (Table 2).
- the heat-treated samples in an air atmosphere showed mass losses depending on the treatment temperature of up to 10%. Since the oil content caused a mass increase, a possible loss of wood substance as a result of the oil heat treatment could not be determined exactly.
- ASE improvement of samples treated at 220 ° C was of a similar order of magnitude for both types of treatment, around 40% (Table 4). The degree of improvement was dependent on the relative humidity. The ASE decreased with increasing humidity, whereby samples treated with higher temperatures showed smaller differences than samples treated with lower temperatures.
- lignocellulose-containing material treated by the process according to the invention has increased dimensional stability, paint on the wood surface is better than untreated material.
- the lignocellulose-containing material treated by the process according to the invention has due to the oil loading during later processing compared to the previously known Processed material has the advantage, among other things, that it is easier to machine edit and nails can be driven in easily. On top of that prevented by the oil from the formation of health-threatening fine dust or is at least greatly reduced.
- the oil loading in the process according to the invention easily adapted to the respective intended use of the products and for example for wood products to be brought into the ground are chosen higher than for those that are only exposed to weathering without earth contact.
- Another advantage of the method according to the invention is that the oil after Treatment is absorbed very quickly, so that a few minutes after the treatment results in a dry surface of the wooden parts.
- Linseed oil and rapeseed oil have been tried out in practice, with comparably good protective effects let achieve.
- An undesirable embrittlement of the lignocellulose-containing material can be reduced if the heat treatment is carried out in an oil bath in the absence of oxygen.
- the oil can also function as a surface coating agent take over when the liquid bath after heat treatment cooled with the material in it and then this in a room climate air-conditioned and then heated to 60 to 180 ° C. By this cooling and Subsequent heating creates a closed, hardened surface on wooden surfaces Oil film. This also means that the brown color created by the oil can be achieved the surface is more permanent, while otherwise oiled wood surfaces in the Nature quickly fades.
- the oil has an initial temperature of at least 180 ° C. hereby fast energy-saving compensation is possible without causing cracking on the wooden surface of materials containing lignocellulose, also with moisture content comes about fiber saturation and larger dimensions.
