This is the minimum that need to know about wood before you start the impregnation of wood in an autoclave. To obtain correct results it is necessary to perform the loading of wood in an autoclave (the same breed, one section, the same humidity – Is the perfect and the best option). Autoclave – a pressurized vessel in which pressurized fluid 10.12 kgf/cm2 the process of impregnation. The impregnation process is carried out in accordance with gost 20022.6 – 93 by way of full absorption of "vacuum-pressure-vacuum." Indicators of quality of impregnation – the biological stability of wood, the depth of penetration and absorption of an impregnating liquid. The achievement of certain performance durability of wood provided the necessary quantity of absorption (in terms of dry matter or concentrate) and a depth of impregnation. Processing technology of wood preservative under pressure – is the most promising and qualified in the processing and wood preservatives. Impregnating wood protection against fungi, mold, rot and insects in more severe conditions.

There are different technologies impregnation (impregnation) of wood. Here are the two most Popular: Vacuum – atmospheric pressure (Vac-Vac, Double Vacuum). The penetration of money into the tree to a few santimetrov.Primenenie method of impregnation vacuum – atmospheric pressure and vacuum can reduce processing time. For this method requires special equipment – an autoclave, a pressurized cylinder, where you can create a vacuum or pressure. After loading the autoclave material creates a vacuum (0,075-0,09 MPa) for 10-15 minutes, then in an autoclave, without interrupting evacuation, serves an antiseptic, and then make the pressure in the autoclave equal to the atmospheric and timber kept in the solution 5-30 min. As a result, the pressure drop solution penetrates into the wood. After impregnation in an autoclave create a vacuum drying for 10-15 minutes.

The depth of infiltration is the same as in the way of hot-cold baths to 10 mm, but the time of impregnation is reduced to 1 hour. Vacuum – pressure – vacuum (Vacuum Pressure). Used for the deepest penetration of the antiseptic composition in the timber. Depth of infiltration can be increased slightly, using the method of vacuum – pressure – vacuum. This method allows us to introduce the greatest possible amount of wood preservative at the greatest depth. It is often used for impregnation with flame retardants (flame retardants). Timber placed in an autoclave and a vacuum (0,07-0,085 MPa) at 15-60 min. Then fed impregnating solution and create pressure 0,8-1,4 MPa. Material can withstand the pressure or to full impregnation or soaking up the required depth. After impregnation of a vacuum (0,07-0,085 MPa) for 40 min for drying material. Quality of impregnating determine the sampling and calculation of the absorption of protective substance and depth of infiltration by staining wood substance itself or an indicator on it.

Looking into the past, we can follow that with time, with the development of science and technology, there are all new and new building materials and technologies. The famous engineer, architect Eiffel, to realize their own, in fact, a unique project that showed people the earth with a bird's eye and the sky above big cities with skyscrapers pierced the tower of glass and concrete. However, despite all this, even today in the xxi century, the century of computer technologies and Multilevel Information Systems, a tree, like many thousands of years ago, has found application as a unique building material – laminated veneer lumber and laminated beams. I'm sure many even ever heard of these construction materials, but hardly anyone thought about the question: 'And what is the best laminated veneer lumber as compared to conventional wood? ". Resort to the help of expert opinion and, above all, look at what is called laminated veneer lumber.

That's what gives us the definition of the project Glossariy.ru: 'Multi-laminated timber – carrying a constructive element, made of wooden planks, glued together in parallel to the grain. " In other words, laminated board created by gluing wooden slats (design elements) with special adhesives so that the fiber slats arranged alternately in different directions. This is primarily provides strength and reliability of construction materials, as well as eliminates the 'pasting' timber by physical or isothermal exposures. Despite the fact that the building materials made of laminated wood appeared long enough in Russia, they began to gain its popularity only in the last 3-4 years. In Western countries and in Europe a lot of people prefer wooden houses from glued beams rather than "boxes" of glass and concrete. I'd like to hope that our country is in the future, too, will become a trend. Because overseas comfort of your home, and even more home from laminated veneer lumber, environmentally friendly building material – it symbol of security and prestige. Today, it is difficult to talk about any accurate forecasts for the construction of wooden houses in Russia, but it is already clear that the industry simply is growing at a frantic pace, the annual turnover companies multiplied several times, but as always critically-minded experts, in this case, predicting the market of construction materials from laminated veneer lumber 4-carat growth already this year.
