Protective Materials Copper

The main cause of the decay of wood to be found in the juices of wood, so you should strive for a more thorough removal of them, that is to desiccation. If the wood is well dried, it rots very rare. It was suggested that many ways saturated solutions of various salts, wood, resins, creosote, etc. in order to prevent rotting. And, indeed, many of these funds reach the goal, but because of the complexity of application and as a result of significant changes in the natural color of wood joiners they do not fit. If you saturate the wood with a solution of creosote, it is, first, turn black, and secondly, to acquire such a pungent odor that becomes unusable and difficult to use in residential installation. Therefore, creosote impregnated sleepers and basically telegraph poles.

We tried to find such relief convoys that they are not spoiled appearance of the tree and it is not clouded construction. One of the these compositions, no doubt, be regarded as an antiseptic water-based. Saturation of wood is not exposed to either rot or wormhole, as proved by a series of experiments made by various researchers and enrich tree with copper sulfate can be that way. Pre-evaporated tree is placed in a hermetically sealable copper cauldron in which pour the right amount of copper sulfate solution, heated to 400, then closed boiler and pump up the solution until the boiler pressure reaches ten atmospheres. Half an hour later the pressure weakens, the tree is removed from the shell and dried. Saturate the tree with copper sulfate can be another way. But this method is applicable only to freshly cut trees, which can still be recovered movement juices. This is a significant difference and a significant disadvantage to him, soaking will be less reliable due to the presence in the tree of the plant juices.

Wanting to sate solution felled tree, placed it on the ground, closer to the saws across the butt, leaving a small nedopil. Then underneath a log drive the wedge, thus cutting the gap widens upwards, and both sides of the timber are tilted slightly from the ends of the cut. In the extended slit cut end is inserted a thin lead pipe, a few yards in length, which is connected to the other end with a vessel containing a warm solution copper sulfate and placed on a (possibly. greater) height. Of course, the sides are cut zakonopachivayut oakum and tar, so the solution is poured out. Vessel and a protective treatment for wood cutting in place under considerable pressure and gradually included in the tree passes through the length of his and follows from the free end of the solution is mixed with wood sap, and replaces them. At the end of 3-5 days of wood soaked through, and can be proceed to its' drying in the usual way. A solution prepared from 400 g of copper sulfate in a bucket of water. Saturated with copper sulfate treated wood is much harder. At present, available to a wide range of antiseptic funds and virtually all construction companies use wood preservative to protect wood structures.
