Polyvinyl chloride, or, as it is a standard cut, pvc – it is a thermoplastic polymer. Polyvinyl chloride – one of the most valuable chemical products. pvc is the oldest artificial material and looks as plastic white. pvc is a raw material for the manufacture of more than 3000 kinds of products used for various purposes in the light industry, food industry, heavy engineering, electrical engineering, in manufacture of building materials and medicine. Analyzing the use of pvc on a global scale, it should be noted that more than half of all items made from it are used in the construction industry. Take, for example, although would be well-known pvc windows. In the construction sector polyvinyl chloride has undeniable advantages. It is easily installed isravnitelno inexpensive.

For quite a long pvc replaces conventional materials. Now more and more people establish, for example, plastic windows instead of wooden ones. pvc replacing traditional building materials such as wood, clay. Keith Yamashita: the source for more info. Polyvinyl chloride is used in many fields, appears in the production of plumbing fixtures, window profiles, pipes and so on. Previously, it was often used in the manufacture of phonograph records and vinyl media.

pvc pipes are flexible. If the pvc mix with plasticizing agents, it will have a more flexible structure. The proportion of plasticizer may reach 30%. Satyavrat Shukla may not feel the same. This pvc is used in the manufacture of clothing (eg artificial skin), and finishing materials, as well as for plastic hose and pipe installation, lining the surface layer and the insulation of electric cables. Hard polyvinyl chloride, or as it is called, vinyl liner, has a high mechanical strength, good dielectric characteristics, significant water and chemical resistance. But all is not well, there are drawbacks. It is not a high impact resistance and cold resistance (-10 C) and low temperature operation, up to 70-80 C. pvc is resistant to Effects of alkalis, acids, kerosene, water, industrial gases and alcohols. Physiologically safe. Polivinihlorid produced by polymerization monomervinilhlorida. about 57% of the total mass of chlorine, so the mass pvc must be less than the lubricants, in comparison with many other polymers.

Unfortunately, the domestic construction industry is often the case situation is that after the official commissioning of the object where there is room to do something. " We have to re-perestilat floors, change the wiring, plastering walls, etc. Marriage becoming one of the most important industry issues. The fight with him – in the interests of each developer, in any case, those who care about their reputation. Not a single SNiPs At present, among many builders There is The view that domestic building construction regulations are outdated and no longer valid. As a consequence, increasing disregard for these regulations in the process of erecting buildings. This fact is noted and a leading specialist service state construction supervision and examination of St. Petersburg Sergei Konoplev.

"If you hear from someone that the construction regulations are outdated, do not trust him – he says. – Russian standards meet the highest international standards, but sorry that is not always respected. " Scale of the problem demonstrated by the results of a recently erected check in the capital of prefabricated houses. Thus, during its 293 violations were found requirements for construction and installation work and found many other errors. It should be noted that this test was only carried out for new buildings that are erected within the municipal order. Similar information on commercial real estate sector, but there are all grounds to assume that the cases there are no better. In any case, for marriage now is all that does not meet the specifications described in snip.

Seeing the alluring advertisements about buying and installing new windows, hearing the recommendations of warmth and coziness of home and friends, many are thinking about how to make successful acquisitions in the form of plastic and wooden windows, or puzzling question of glazing your balcony or loggia. Along with thoughts on the new windows the question arises: how much will it cost and whom to entrust such a responsible action. Most likely, having studied information on various resources, taking advantage of "online calculator" you'll be in the wild delight of the received value, but the serene joy will last exactly until you see the real value of your new windows or glazed loggia after coming .

In spring and autumn there are hundreds of new companies offering box at a low price, but what you can get a result? -Illiterate and irresponsible approach to the timing of manufacture of windows, unqualified delivery planning, poor installation, lack of warranty and after-sales service.

As a result, money spent, and the result is far from desirable. Since the departure and consulting project manager is usually provided by various companies as a free service, you have the possibility compare, select and determined! Enjoy! Note the main points when choosing a window company: 1. Make sure whether the services offered by the codes on activities, registered tax authority; 2. Study in detail the company's contract, which must be stated: the nomenclature, equipment, price and warranty, 3. The presence of a payment document; 4.

Learn about the company itself: for how long it on the market, what kind of projects led, who carries out construction works, and what they guarantee, in the study of information about the company should not trust negative reviews on various "forums", this information may be unreliable. Guarantee for the window company can be: letters of recommendation from the producers profile, end-customers and, of course, a photo gallery of works 5. Having its own window manufacturing (assembly glass, frames, shutters, etc.) 6. Pay attention to the provision of a contract governing the terms of warranty on the finished product and provide you with variety of services. 7. Be reasonable and logical! Treat with suspicious of companies that bid which is significantly lower than in competitive firms.

Curtains fluttered anxiously, and the windows sounded eerie groans and howls, as if there were raging ghosts I think this excerpt from the script to a horror movie? And here and there! This is easy to imagine, if you listen to the explanation employees of unscrupulous manufacturers and retailers of building materials. It happens that their failures are blamed on the interference of supernatural forces or tricks poltergeist. Earlier this year, anecdotal case occurred in the Ukrainian city of Donetsk. There's "Poltergeist" showed up in the most ordinary flat panel high-rise building. Pensioner Galina replaced the old wooden windows with new plastic, laid out for them a lot of money. But a few months later the problems started.

The owner noticed that in windy weather on the closed wing is blowing, and the apartment is clearly heard the wind whistling. The woman lodged a complaint with the window company, but experts by visiting the ill-fated apartment did not hear any outside noise – obviously, because that day was calm weather. In response to repeated requests to solve the problem pensioner hinted at its mental illness, and then offered to do call the priest! Like, the case in "unclean" power, settled in the apartment! In fact, poltergeist here at anything. "The cause of drafts often becomes commonplace Failure of technology installation – explains Rafik Alekperov, head of customer service propleks Group of Companies, the largest Russian producer of pvc window-profile of Austrian technologies. – Tightness of the porch, shutters may be compromised if the installation of windows in the field blocking were not fixed additional distance pads and gaskets.

Moreover, the production and use of antiseptics, water-based is tending to a constant growth. The reason – the constant tightening of environmental legislation that restricts the content of toxic components in the formulations of antiseptics. Antiseptics are in the form of impregnation or coating. Impregnation characteristic antifungal and antimicrobial action – a kind of antibiotics for the tree. Effect of impregnation consists in the fact that the solution is deep (up to 10 mm) timber, spreading around the antimicrobial germicidal action. But the coating method of action is different. Surface treatment is an kind of flexible film with water-repellent abilities that protects the wood from moisture. Impregnation uncoated very soon lose their properties under the action of water.

This covers the film does not interfere with the tree to "breathe" through it out vaporous moisture which eventually accumulates in the timber. Also, the film include metal oxides, warning damaging ultraviolet rays that can ruin the appearance of a building material – under such a radiation timber loses its color and becomes dull gray. Finishing the film there are different colors, as well as transparent and translucent, shiny or matte. Transparencies emphasize the texture of wood, highlighting patterns of cut. Translucent color report tree needs shade, not masking textures and patterns of wood.

Impregnating and coating compositions are divided into internal and external work. Produced and universal combined structure. Blue blue wood occurs mainly at high humidity and a temperature of +10-25 C. This phenomenon contributes to the immobility of the air surrounding the timber.
