Polyetherimide

The main purpose of these materials – to dissolve and dilute the paint materials. Knowing the composition and appointment of solvents and thinners, can be successfully used them for other purposes, for example, for the manufacture of adhesives, degreasing materials, etc. Simple solvents Acetone – dissolve natural resins, oils, polystyrene, epoxy resins, vinyl chloride copolymers, polyacrylates, chlorinated rubber. Gasoline Galosha, B-70 dissolves rubber, hot form – polyethylene. Benzene dissolves oils, fats, waxes, rubber, cellulose ethers, some silicone resin in hot form – polyethylene. Butyl acetate dissolves cellulose ethers, oils, fats, chlorinated rubber, vinyl copolymers carbinol resin. Dichloride dissolves dammar, Ku-maroon, vinyl polymers, acrylics, polystyrene.

Xylene dissolves alkidnostirolnye and divinilatsetilenovye (lac 'Etinol') polymers. Methyl acetate – acetone analogue. Methyl alcohol (methanol), dissolving the cellulose nitrate, polyvinyl acetate, novolac resins. Turpentine dissolves Kopal, dammar, colophony. Thinner oil, al-kidnostirolnyh and epoxy paints (varnishes). Solvent dissolves oil, bitumen, rubber, urea oligomers poliiefiry tetroftalevoy acid Polyetherimide and polyesterimide. Toluene dissolves shellac, Kopal, cellulose esters, polystyrene, silicone resin. When mixed with other solvents (he – the main component) dissolves epoxy, vinyl and acrylic polymers, chlorinated rubber, skinny alkyds.

In the hot polyethylene dissolves. White Spirit (Heavy fraction of gasoline) dissolves fatty alkyds, butyl-and tsiklokauchuk, polibutilmetakri-lat epoksiefiry. Cyclohexane dissolves etiltsellyu-vine oils, fats, waxes, rubbers. Cyclohexanone dissolves cellulose esters, fats, oils, most natural and synthetic polymers, polyurethane. Acetate dissolves most of the polymers. Cellosolve dissolves urea oligomers carbinol resin polivinilformaletilal (vinifleks).

Decorative Thickness

This allows you to move "dew point" in the insulation (Styrofoam) and significantly increase the efficiency of lightweight concrete in the construction and significantly extend the life of the building. Reade Griffith is often quoted as being for or against this. The required thickness of expanded polystyrene insulation boards for the outer insulation of the walls (in the "wet" the facades) required thickness of insulation (EPS) at minimally acceptable heat resistance of the walls of buildings of different purposes and different climatic conditions (in accordance with SNIP 23-02-2003 "Thermal protection of buildings") varies according to region of Russia and the region application of thermal insulation. Terms perform calculations for the table: The calculation is based on the requirements of SNiP 23-02-2003 For sample calculation taken a group of buildings – residential, medical and child care centers, schools, boarding schools, hotels and hostels. With the new construction required thickness of insulation is determined by the following constructive solutions – bearing portion of the wall is made of ceramic bricks or corpulent rock thickness of 380 mm and the outer protective layer – 4,5 mm plaster reinforced with fiberglass, the thickness of the decorative layer is determined by the fraction of the filler. The wall on the inside of a finishing plaster layer thickness of 20 mm. The coefficient of uniformity of heat engineering walls – 0.95. In the reconstruction of additional insulation thickness was determined with the following conditions – the walls are made of mud brick corpulent thickness depending on the purpose of the building and construction area – 380, 510, 640 or 770 mm with 20 mm plaster for buildings of the 1st and 2nd groups, and without plaster – for building third group. The protective layer of additional insulation is made of plaster 4.5 mm thick, reinforced with alkali-resistant fiberglass, and the thickness of the decorative layer is determined by the fraction of the filler.

Facing Clapboard Lining

With the present development of production become increasingly popular finishing materials, made of drywall and plastic. But such material as wood, time-tested, still in favor. And of course the role of cladding material itself the best option remains the wooden paneling. With groove and tongue, it is easy to assemble and versatile in use it is possible to "sheathe" any building and not just facades, but premises from the inside. The most popular wood siding – siding is made of pine – it is one of the cheapest, and it is to this day, holds first place in the category of price and quality. But if you want that would-room with his hands, in this case, the maximum lime suit lining, because it endure high temperatures and very poorly heated, and compared with the pine tar does not allocate.

Linings are made from different woods such as alder, oak, mahogany … .. but because of the very high prices they are used much less frequently than pine or lime lining. This lining material is divided into four classes – Extra, followed by classes – A, B, C. Lining-class produced the most expensive and vysokochestvennyh parody of wood, as it is free of knots and, accordingly, it is very expensive. The lower class bunks, the lower the quality and the higher the number of knots. Before you finish the installation of lining, it must be during the day for the acclimatization of the material to withstand the premises for which it is intended, and prepare all the necessary tools. You will definitely need the following tools: screwdriver, drill, wood screws, 75 and 35 mm, electrofret, screws, quick installation, wall paneling, klyamera mounting studs or 20 mm, level, hammer, plumb, mounting thread, hangers, stapler, staples, cabin, vapor barrier, mineral wool, wood block 40 * 50, and before any work you need wiring, set up to power.

Sochi Load

Falling off the roof of snow and ice mass is high risk to human life. In the Finnish collection of construction orders and instructions stating that the entrance to the building and all its approaches, as well as playgrounds must be protected from falling from the roof of snow and ice. This regulation also applies to all paths and walkways surrounding the building. When the roof slope exceeds 1:8, protected from the falling snow are installed on the roof snegozaderzhateli, awnings over the front door, as well as planting shrubs and regulatory approaches to the building. Snegozaderzhateli installed close to the ledge on the continuation of the wall, so that the load extended to the supporting structure. Snegozaderzhateli installed in a continuous series by building. Snegozaderzhateli made of galvanized steel or other corrosion resistance materials.

Fasteners snegozaderzhatelya must be solid construction and fitted in such a way that does not entail the occurrence of the roof. On steep roofs and in areas with high snow load may require several snegozaderzhateley series. For example, in Lahti design snow load 1.8 kN/m2, and in the mountainous areas of Sochi – 6.0 kN/m2. The following table shows the maximum length of the pitch for a single row snegozaderzhateley depending on the snow load and the angle the slope of the roof. In the example highlighted in the table, the slope of the roof 18 'and the estimated snow load is 2.0 kN / mg. At the intersection of these lines are visible maximum length of the pitch for a single row snegozaderzhateley, 9.7 m. This means that if the actual length of the slope is greater than 9.7 m, it is recommended to install an additional number of snegozaderzhateley.

You also need to take into account that, if not installed snegozaderzhateli along the entire length of the slope, but only on certain areas, the actual burden they may exceed the estimated snow load for the area. The actual snow load could exceed the estimated also in the spring after a snowy winter, when the snow the roof is wet and heavy. In this case, you must still pay attention to the structural strength of the roof and, if necessary, clean off any excess snow from the roof. In recent years the market roofing elements bezhopasnosti roof (snegozaderzhatel, fences roofs, ladders, catwalks) acquire an increased interest from both the end user, and from vendors of roofing materials. Please explore the range of one of the producers of the security features of the roof – tubular snegozaderzhateley, roof rails and ladders.

Using Drywall

Drywall is widely used in modern construction, primarily in order to align the walls and ceilings. Also, this building material helps to soundproof the room. Plasterboard has a light weight, can be easily transformed, so that in the modern interior design, it stands in the most unexpected combinations. The name "drywall" well reflects the structure of this building material. Roughly speaking, drywall is a slab of plaster layer, covered on both sides of sheets of cardboard.

There are some types of drywall. Ordinary gypsum board used for interior residential spaces – rooms, corridors, where the humidity does not exceed 70%. Bathroom, kitchen and other rooms with high humidity, a special moisture-resistant drywall. Vlagoottalkivayuschie properties of such a building material acquired by impregnation of gypsum special substances, repelling moisture. Although such material and are used in environments with high humidity, it must be additionally protected by covering with waterproof paint.

Fire-resistant gypsum board is also produced, which is used in areas with high risk of fire or high temperatures. When a manufactured building material, the gypsum is added fiberglass, which prevents the destruction of the material under high temperatures. Developed even drywall, which combines the quality of water and fire, but it is definitely more expensive than other types of drywall. The main preimsch6stvami drywall is its plasticity, the ability to conceal surface irregularities, which can not disguise the plaster, and, moreover, drywall – it is environmentally friendly building material. But the drywall has its drawbacks, in particular, it will spoil by moisture, is a useful floor area, is worth more than other building materials. If you are going to equip the apartment with the help of this construction material, in addition to the drywall you need to buy either: 1.

Technology Application

We recommend that you use to plaster the walls 'stucco'. To understand the benefits of using 'plaster', it should consider the following features: applied to the wall with a thin layer that allows you to display a wall with a minimum of material, does not shrink and does not crack, dry out in two times faster than conventional plaster putty consumption of plaster surface is greatly reduced. If take into account all these factors, the total cost of materials compared with similar work using conventional cement-sand mix will remain unchanged. However, you will significantly save on time, the cost of the work and certainly get better and more reliable result. Before applying the plaster, the wall is applied to the soil depth of penetration, which allows a layer of plaster is stronger hold on the wall. In plaster wall in a fiberglass reinforcing mesh, which allows you to smooth out the voltage inside the plaster and avoid the appearance of microcracks.

Next on the surface of the plaster is applied several coats of putty. Before each layer of the ground surface. Then the wall is polished and applied topcoat sealers (special putty with a small fraction). If the wall is being prepared for painting, polishing and then coating produced by the light special high-powered searchlights, which allows you to keep track of the smallest flaws on the wall. At the end of the pre-treatment of the wall is ready for application of finishing materials (paint, wallpaper, decorative plaster, etc.) Technology Application of different types of finishing materials are not identical. Next we take a closer look at some of them.

Paint the ceiling preparation does not differ much from the training walls. Device screed and waterproofing First, using gidrourovnya done marking of the floor level. Of the place, most raised relative to the rest room, then on the walls made a mark of zero.

Russian Floor

Before you buckle your hands is the surface of the concrete slab is cleaned of dust and dirt. Ideal to clean concrete impossible, so then primed surface binders. Primed surface provides good shvatyvaemost with screed. It is important for either sex, but especially for ceramic tile. If buckle under the tile poorly grasped with the cooking surface, then walking on a tile will be heard the characteristic sound of, and eventually the floor will be uneven and the tiles will start to detach from the base and “fly.” In Russia traditionally buckle made of dry concrete mixtures. Since the mixture of concrete and sand in any proportion – not a very durable material, then it is added adhesives. Before the screed will be laid floor covering, it must dry. An experienced master of the construction firm will always be able to pinpoint the degree of humidity tie, I will only note that the average time needed to dry – 45 days.

After this, the screed is applied waterproofing cover, and on top – moisture-resistant sheet of plywood, 12 mm thick. Plywood does not interfere, under any cover, but it is especially necessary for flooring, or high humidity (water leak or just a few days of early autumn, when is wet weather and central heating is not included) can destroy the most beautiful and expensive hardwood floor. In the European technology for the manufacture of cable ties are special self-leveling mix – so called self-leveling floors. Under these mixtures for additional noise and heat insulation are often put a layer of styrofoam, and for extra waterproofing on top plank polymer film. This floor dries much faster common ties (approximately 10-15 days).

Directly to the self-leveling floor can be laid tile, laminate and carpeting. To lay the same parquet necessarily need a layer of plywood. In addition, the bulk layer has a floor very small thickness (25 mm.), which is especially useful in homes with low ceilings.
