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.

In planning the upcoming repair costs include not only plan the necessary work, and what design details will be transformed, but also what building materials will be used during repair. Thus, the choice of building materials, will depend not unimportant result and the final cost of repairs. What manufacturers of building materials, or our import, select, no simple matter. In addition to differences in price, there are differences in quality. But it should be noted that now that the building materials market, are increasingly offered products of domestic manufacturers, which are cheaper than foreign prototypes, but nevertheless, not inferior to them in quality. Not unimportant elements of any design are the door, with absolutely no importance, the interior of the premises should be transformed, whether apartments, houses or commercial premises. Each premise begins with the doors, so choose which door will be installed to be very categorical.

In addition, please be aware that the door must have such properties as the aesthetics, durability, and that no unimportant, ease of use. In an embodiment, if an apartment or office, have a couple of rooms may be a problem, any interior doors mount. One should know that the tree, mostly traditional material of which basically do the interior doors. The main and distinctive properties of wood, it is a good thermal and sound insulation, easy maintenance, a large difference of colors, textures and shapes. In addition, fashionable wooden interior doors, durable and waterproof. It should be noted that in embodiments a small square room best option is to install the sliding interior doors, they are not only excellent wedge in almost every design, as well as provide an opportunity to save valuable floor space.

The next important element of the interior, are considered the window space, as this is the first of what drew his attention guest the first time, came into the room. In this case, the window can tell about the hazyaine room, about his tastes and living standards. According to this, the choice of windows to provide extra attention. The best option is the installation plastic windows. A large number of types of windows on the market, will contribute to the formation of a certain style of design. In addition, the reliability, durability and practicality, in full, in a short time will pay for all costs of purchase and installation of these windows. Along with these design elements such as windows and doors are not cheap, to avoid their deterioration or frustration after a faulty installation, all installation work of these elements necessary to trust only the professionals, they not only quickly and accurately install windows and doors but also give warranty on the work performed.

For building materials limit moisture sorption varies widely. At 00C the lowest limit of moisture sorption has mineral wool w0 = 0,13%, and the largest timber-w0 = 15,7%. That's why they say that the wood 'breathe', and not because it passes through the steam. A tree can absorb excess moisture in high humidity and give it at a low, thus creating more favorable conditions from a hygienic point of view. Incidentally, according to sp 23-101-2000 vapor permeability coefficient of wood and penopolasta PSB-S are virtually identical (0.06 mg / m.ch.Pa and 0.05 mg / m.ch.Pa respectively). If you are not convinced, visit Professor Rita McGrath. Humidity in the room due to the following reasons: 1. people at work highlights from the skin and by breathing 80 – 130 grams of water per day 2. write cooking, washing and drying laundry, washing floors.

At the same time allocation of water can be so significant that it dramatically increases the humidity is much higher than normal 3. Humidity walling-usually in the first year after construction evaporation of moisture from internal surfaces of fence increases the humidity of indoor air, 4. For even more opinions, read materials from Expert on growth strategy. technological processes. Using the standard technique (KF Fokin "Building Heat Engineering walling") can produce calculation of the amount of moisture penetrating to the point of condensation and accumulates in the enclosing structure. Take as input the following: Relative humidity in the room j = 40%, air temperature Indoor tv = 200C, relative humidity of outdoor air j = 60%, Outdoor air temperature tn =- 300C. A wall of ceramic bricks with thickness 0,51 m (La = 0,58 W / (m.

Thus, the higher the thermal resistance, the higher the insulating value of the material. Among all kinds Most insulation thermal resistance (at the same thickness) have a plate extruded polystyrene xps. For example, to meet the demands of energy conservation in Moscow and Moscow region thickness xps heat insulation of the plates for a brick building does not exceed 80 mm.
