106357 Natural impregnation of pine wood and use of the method method for the conservation of natural resources and the use of den den

The invention relates to peeling of a growing pine tree and to a protective treatment for producing decay-resistant wood. By mechanically directing the growth functions of the wood itself, the impregnation effect is achieved on the surface of the wood trunk, while the treated vertical wood is protected from bluing and drying cracking during processing by using suqing or paper.

The wood of the growing tree and the dead wood of the felled tree are the components of the natural life cycle and the nutrients and substrates of the natural seed and insects which cause the destruction of the wood in various uses.

Numerous different anti-rot coatings and topcoats have been developed to protect outdoor timber. to protect wood from decay and insect damage. In order to make pine wood and other wood products resistant to rot and insects, a variety of toxins are commonly used: anti-blue, salt-impregnating and creosote-impregnating and insecticides, and anti-rot paints.

In order to make wood products durable and hard, various heat treatment methods have been developed with the aim of heating and pressing those in the wood. substances in such a form that they are no longer in a form that can be used by pests and insects or that they cannot penetrate hardened wood.

For a very long time, pine wood has been barked upright to provide tar and durable construction wood, leaving a narrow living band in the trunks, giving the wood a growth effect that increases the resinous resin content of the surface wood. This peeling treatment has also been supplemented by treating the peeled body portion with a chitin preparation and salicylic acid to prevent cracking and striking of the blue fungus.

All of the protection methods mentioned have various disadvantages and disadvantages.

Poisonous solution dressing has been used to protect round bark wood from insect damage and reproduction. These poisons cause residues of toxins in timber and timber products, which are no longer allowed in the products.

The effect of paints and paintbrushes extends only to the surface of thin wood. The shielding effect is often short-lived due to cracking caused by the moisture moistening of the wood.

Undried pine lumber has been commonly treated with chlorophenol poison by spraying or sprinkling to prevent discolouration caused by blue fungi. These powerful toxins, which cause various environmental debris and occupational health damage, are now completely banned. Even the less diluted antifouling agents used today produce a variety of harmful residues in the liver and body of the workers who handle them, and in their end uses, they emit gaseous pollutants and are replaced by new harmless treatments.

Toxic wood preservatives can be absorbed into the wood by various pressure impregnation techniques, but these include arsenic-containing impregnating toxins induce toxic gasses indoors and risk of cancer treatment workers. Since 1998, the Finnish Environment Institute has recommended the use of saturated wood using arsenic only on a limited scale without being processed at the site. MyTkkwood is not suitable for burning at all because of the toxic gas emissions.

Heat treatment of wood, in turn, reduces the risk of decay. but makes wood fragile and expensive to handle due to transportation and high energy use.

The differences between pine and heartwood have been presented by e.g. Matti Jalava 1952 in The Structure and Properties of Wood.

a The pine bark impregnation in Finland has been most fully presented by architect Panu Kaila in his book Talotohtori (1997).

In field trials conducted by the Ostrobothnian Stundars Museum Museum in the Pirttikylä I (Forest Science 3 106357 student Fredrik Pressler in 1997, Master of Science in Forestry at the University of Helsinki), the bleaching and cracking of the peeled hull could not be prevented.

To date, no method has been found for treating growing wood with some chemicals to provide a saturating effect without barking.

The method of the present invention improves the efficiency of organic non-toxic impregnation by peeling of pine wood and overcomes the present deficiencies in peeling treatment.

As regards the features characterizing the invention, reference is made to the claims section.

In the method, the tree is stripped and protected in the spring in April, in May at a stage when the bark is soft and peeling off easily.

The appended drawing describes the structure of a pine tree structure and the processing technique. In Figure A, depicts a cell in a dark, resinous, aged and dead heartwood of a pine, which has been dried and trimmed by a cellular pine into a solid and thick wall. Surface tree, or mantle tree B, is a light, living, aqueous and nutritious open porous cell.

Dried and felled dried wood gets wet, dries and cracks in moisture variations. Cracks and open cells are penetrated by fungi and beneficial substances with water and air *; starting from the destruction of the wood and the wood begins to oxidize, ie slowly returns to its surface.

In vertical peeling, a three or four finger wide bark strip E is left on the pine tree to keep the tree growing. The body, peeled with protective paper or plastic C, is protected against blueing and excessive drying.

During its two to three growing seasons, pine tree develops pitch tar D and concentrates to produce resinous resinous materials, whereby it exfoliates both the surface of the barked portion and the surface area beneath it to be resinous and rot and insect resistant to the same as the pine heartwood portion. Wood removes cell water from this surface wood 4,106,357 cells, drying the wood, reducing the water and nutrient content of the cell walls and replacing them with resinous substances. In this way, cells B become solid, thick, and hard-walled, so that this tree becomes durable and thereby prevents alien organisms from invading and destroying it.

The close protection on the wood surface - increasing the thickness of the slag strip E further increases the density - reduces the flow of resin onto the wood surface and controls the spread of the resins as desired throughout the redwood.

Peeled wood dries slowly only through its own drying process through the needles and prevents cracking with resin and hardening of the wood. There is no harm in providing airtight protection for the tree trunk growth band.

It is a matter of mechanically inducing the natural pine's natural pine hatching process for decades, within a few years.

Natural wood is poured into a saturated two and a half years in the winter.

The protective plastic or paper is removed by tearing off the trees ..

Wood can be used for all purposes that require moisture, rot and insect-resistant non-living wood, either round or sawn.

Because wood chips are also resinous during sawing, they are used as * · · non-decaying, moisture-resistant heat-insulating fiber.

In heating operation, its calorific value is better than usual.

When a very long pile is made from a large pine tree, the tree is treated step by step very high, while pruning the branches. The frame can be peeled and mechanically protected.

The natural impregnation method described is used in pine trees on dry fabrics, i.e. lingonberry, heather and lichen type soils. Their pines are dense, thin-skinned wood and have a higher proportion of heartwood, and the impregnation effect is directed to a thin surface layer of wood and is perfect wherever.

Claims (2)

1. A method of natural impregnation of growing pine by utilizing barking of trees and the tree's natural production of chains, characterized by the fact that the barked pine tree is protected at the bark during the impregnation season against fungal and crack damage with paper or plastic protection. 2. Use of the method for the natural impregnation of growing tallow according to claim 1. characterized in that the impregnation method is applied in the treatment of pines on dry and barren moors.
