Coating materials are widely used in construction of residential houses, office and industrial buildings, bridges, buildings, and also in the works for their repair. It uses all kinds paint materials: paints, primers, sealers, enamels, solvents. Very popular alkyd paints and varnishes, the production of which the initial components are alkyd resins and polymers obtained by polycondensation of glycerol or pentaerythritol with phthalic anhydride. Alkyd materials are divided into glyptal (a typical representative – GF-021 primer) and pentaphthalic (enamel PF-115). Pentaphthalic enamels are available in a variety of colors and can be used for painting as wood and metal products and structures. In order to extend the life of alkyd paint enamel is applied to the primed surface.
Often in the construction of the painting works to the shortening of the painting works are used nitroemali (enamel NTs-132) with the ability to dry for several hours. Nitroemali best applied with a pneumatic atomizer as well as applying the enamel with a brush is difficult because of the rapid film formation. Nitrocellulose paints also applied to prepared and primed surface. As a rule, nitroemali available ready to use, but if necessary to dilute the solvent 646. Solvent 646 is better to use, made in accordance with formulations according to GOST. Otherwise, you can use the paint material.
Surfaces prepared for painting, cover the primer GF-021 or equivalent. The use of enamel NTs-132 works in painting nezagruntovannyh surfaces is not allowed. The facades of buildings and structures are painted with acrylic paints, and with high ecological characteristics, as well as organosilicon materials, which provide weatherproof coverage. Such organosilicate compositions, such as OC-12-03, applied for painting surfaces, concrete structures and masonry structures. It should be borne in mind that the paint on the base organosilicate compositions in addition to decorative and has fire properties, since the coating nonflammable.
Therefore, when forehead tax of water vapor transmission, the different results of test completely can be gotten under different conditions of test. That is completely different to the oxygen results and other regular gases. Therefore, the widening of scope of measurement through test gas alteration or reduction of water vapor difference is not adjusted between the two sides. 4.Conclusion With the introduction of new materials and applications, materials of high tax of transmission are to be used extensively. This article presents some staff, convenient, fast necessary half to widen scopes of measurement of instruments of barrier property. For the time being, emptying, especially emptying in the sides of packing, during test of barrier property, would have to be emphasized, to prevent errors caused for the false operation.
WEB SERVICES Web Services or Servios Web are using to disponibilizar interactive services in the Web or Internet, being able to be had access by other applications, is identified by URI (Unique Resource Identifier), described and defined using XML. The reason becomes that it attractive is the fact of this model to be based on technologies standards, in particular XML and HTTP. Web Services allows that applications interact between itself independent of its platform of development, these applications sends and receives given in format XML, this and the only premise for the communication of a service web. The XML (Extensible Markup Lenguage, or Language of Extended Marking) and a technology that facilitates the document analysis for programs, that allows to the exchange and exhibition of content of databases, and can also be used for exchange of messages in the communication of distributed systems, will not be carried through a deepened study of technology XML since the same it is not fit in the target of the article. Using this technology we can develop software or components of software capable to interact, either sending or receiving information, with others software, not importing the programming language where these had been developed, the operational system where they twirl and the hardware that is used … (GOMES, 2010).
Web Services possess all the necessary information so that other systems can interact with the service, called to the methods and protocols communication, this integration and made through exchanges of messages based on XML this it makes with that the more flexible service is ace varies available platforms in the market, generally and implemented aiming at to responsibility a service in the world-wide net of computers ‘ ‘ internet’ ‘. Better to understand the functioning of a Web Service we go to make a study of its architecture and employed technologies UDDI (Universal Description Discovery and Integration): the UDDI consists of supplying ways so that the Web Services is registered and published in the net this it allows that services are located in form of repositories, another functionality of the UDDI and the storage of WSDL.Atualmente archives exists two standards of development of Web Services, standard SOAP and standard REST or RESTfull, the article approaches only standard SOAP, to follow meets one brief explanation of the involved technologies.
Technology pasta production Manufacture of macaroni izdeliyPodgotovka raw materials to manufacturing pasta meal preparation is: a weighing, blending, sieving, magnetic ochistkeSmeshivanie.Dlya which must mixing pasta flour? Mixing of different batches of flour of the same species in a specific ratio shall be carried out to improve some measure due to the higher raw material. The application requires improvers thorough mixing of batches of flour in a special mukosmesitelyah. Mixing, also, you must use small quantities of container storage of raw materials, especially if the stock is not supported by the necessary microclimate for storage. In Depending on where and what time is every bag of flour moisture in it can vary quite strongly over time. The difference in humidity in the bags can be up to 1 2%, which can lead to unstable pasta press and the entire line in tselom.Proseivanie. Screening is carried out to separate accidentally fallen into the flour foreign particles such as lint, yarn, paper, dry lumps of flour. For screening, is usually used Burat, centrifugal sieve, sieving, and other equipment are fitted with metal sieves with openings ranging in size from 1.0 to 1.6mm.
The most popular flour sifter, sifter is a "Pioneer." Magnetic cleaning. Magnetic purification of flour produced by permanent magnets to remove metallic impurities that may have gotten into the flour as a result of the arrangements. In the field of the magnets, the flour should be moving in a layer of 6-8mm with a rate not exceeding 0.5 m / sec. Such a system of magnetic cleaning equipment is required for the macaroni. Every 4 hours, magnets ochischayutsya.Prigotovlenie pasta dough. Pasta dough in its composition, is the simplest of all kinds test, used in the production of baked goods. Often, the recipe consists of only flour and water. The introduction of any additives and improvers, significantly increases the cost of pasta and forces manufacturers to move into a higher price category.
With all the natural simple – clean it, does not allow pathogenic bacteria to multiply, and resistant to fire and effects of household chemicals, does not attract dust. Linoleum hard enough, is not deformed by mechanical action and temperature difference. PVC vinyl is cheaper, and if you decide to choose it, it is better to natural substrate. The substrate is made of thick natural fabrics allow less tired legs and prevents the accumulation of static electricity. Planning and design of today modern interior design with an open kitchen layout is divided into zones not only by walls or a bar, but with the combined floor coverings. When the joint space space "flows" from one to another, you can either clear to carve out a zone, or, conversely, to make it as a continuation of the previous one.
For example, if a combination of tile flooring and kitchen area will be allocated from the general interior of the apartment. Whatever coating you choose, kitchen should be in harmony with the rest of the apartment interiors, and much depends on the shape and size of the kitchen and on your furniture. However, the most important thing for any kitchen – is safe and most comfortable conditions for work. No beauty can not be justified, if at the time of cooking and other kitchen work owners are constantly in danger of injury. It has become fashionable to organize the kitchen area on the podium, and even when it is technically unfounded.
In this case the owners often do not think about how they will move out of the kitchen into the dining room and back, carrying the dishes and trays of food. Formed in the device the catwalk step can cause constant discomfort and serious injury, so you should always keep in mind about the basic purpose and plan for its cuisine with maximum security. In general, the material for the kitchen flooring must be not only durable, beautiful, and water resistant, but also safe, allowing the kitchen to feel free and comfortable. To take into account all these factors, as well as compliance with the basic your kitchen style apartment or house, it is best to use the services of professional designers.
Introduction the area daeducao is an excellent mirror of the size of the exclusion, the discrimination, the inaquality and the injustice in Brazil. The repetncia and the evasion, forceful soexemplos of this affirmation. Brazil appears enters piorestaxas of reprovao and pertaining to school evasion of the world according to Organization dasNaes Joined for the Education, Science and Culture (TAKAHASHI, 2006). Segundodados of the MEC (IBGE, 2006), only 56.2% of the young in the etria band de14 the 16 years had concluded basic education in the waited age. NoNordeste, in the same period, this index falls for 37,4%. Already osconcludentes of average education, the national tax declined still more, poissomente 37.9% of the young ones up to 19 years had poissomente obtained this fact.
NoNordeste, analyzing the same indicating, the tax of conclusion of the ensinomdio was considered in 2006, the minor of the country with only 20.9% of seusjovens exhibiting a diploma of according to degree to the 19 years. Simply, the school the same continues perpetuating model the question of the conectividade, or of faltadela, it is a real and problematic question, therefore the people who nopossuem access to the TICs present a fragility each maisconsidervel time in the work market. free software.

Roof – top element of the roof (covering) that protects the building from all types of environmental influence. Of course, what the quality of the materials from which the roof is done, depends largely on longevity, speaking without understatement, the entire structure. Thus, surfaced roofing (roofing, polymer-bitumen, bituminous roofing) is a special synthetic material used during roofing and waterproofing work. This soft, roll roofing on both sides treated by a modified bitumen primarily used to cover flat roofs. Quality roofs should have a number of properties, including are: resistance to temperature extremes, exposure to biological agents, to the appearance of corrosion and water tight.
In particular, the material should have some flexibility to be able to perform Roofing work, even in remote places. Roll roofing surfaced is to ensure reliability and quality of its installation nesgnivayuschuyu basis of polyester, glass fabric. When you install a roof frequently used gas burners, but you can use self-adhesive bituminous and polymeric roofing. Consider some of the materials. Roofing Gidrostekloizol (surfaced roofing) Modern, high-quality roofing material, obtained by continuous, two-way application to the foundation of molten bitumen, which consists of petroleum bitumen, filler, processing aids.
When igotovlenii Gidrostekloizola used as a basis: nesgnivayuschie fiberglass materials. It is interesting that the use of nesgnivayuschie basis leads to an increase in the life of the roof to fifteen years. In Depending on the type of foundation, type of dressing and the application of Gidrostekloizol issued the following brands: Gidrostekloizol-TAP, HSS-Gidrostekloizol – used for installation of the upper layer of roof membrane – with coarse grit or scaly on the front side and a polymer film deposited by a cloth; Gidrostekloizol-HSP, Gidrostekloizol-CCI – used for installation of the upper layer of roof membrane with a protective layer and lower layers of the roof membrane for waterproofing of building structures – with a polymer film on both sides of the canvas.
In the era of film cameras 'FED', 'Change' camera repair shops used to lubricate fotomehanizmov bone oil, as more resistant to temperature fluctuations. While the shortage and inaccessibility were commonplace. In the absence of a sale of the oil it offered to produce their own. Here's one recipe: clean of meat bones bull or cow's feet, crush them into small pieces and placed in an enamel dishes and fill with distilled water. The whole product is cooked for 5-6 hours. over low heat, without putting a large boil.
Appeared during boiling foam gradually removed. The prepared liquid broth is cooled, after which surfaced on the surface of the fat collected in separate glass bottles. Then take four well-washed bottles, glass insert them into a funnel with filter bandwidth of the paper. Gradually and carefully pour the fat one of the craters. Filtration of fat is slow and not immediate. When all the fat will be filtered in the first funnel, pour it into the second, then third and so on. Do this for as long as the fat becomes completely liquid. Cooked oil settles in for a month. After that, oil is separated from the precipitate, filtered, and only then apply the grease fotomehanizmov. The mechanisms of most modern digital cameras work without lubrication through the use of special materials.
Plasma spraying allows high-quality ceramic coatings having, except iznostostoykosti, heat and electrical insulating properties. However, the most cost-effective manufacturing of new equipment is a hardening of the methods of spraying and surfacing with subsequent repair of the same methods. In the course of the last few years modern technology sputtering and deposition enabled the import substitution and, in some cases, successful entry into global markets with product updates to manufacturers turbodrills, screw downhole motors and drill bits for drilling Well, conveying rollers for roller conveyors metallurgical industries, geophysical equipment, and many others. Worldwide high-speed robotic complex deposition and / or plasma deposition becomes an inherent part of modern repair production of the transport industry. The introduction of this technology pays for itself within 2-3 years, subsequently bringing a steady income. Supplied by us robotic systems and high-speed plasma deposition was successfully working in industries such as engine building and repair of aircraft components to their highest demands for quality parts, oil and gas engineering, manufacture of parts for heavy trucks.
