Safe Temperature For the temperature of the onset blistering take the temperature at which the already obtained with expanded clay pellets density 0.95 g/cm3. The maximum possible firing temperature is the temperature of the beginning of melting of the surface of granules. To expand the temperature range of swelling using this technique, as raw clay dusting powder granules of refractory clay, which improves firing temperature and avoid melting of the granules. Expanded clay aggregate has the following features: - Easy and high strength - excellent heat and sound insulation - fire resistance, moisture and frost - acid resistance, chemical inertness; - durability - environmentally friendly, Safe, natural material similar to ceramics - a high ratio quality / price. Application of the most widely used claydite finds as a wall material. In some regions of the wall panels keramsit became the basis for industrial-scale construction. Especially effective but the application for the wall panels are well expanded lung keramzite gravel marks 300, 400, 500 (for bulk density). Density structurally keramsit insulation for single-wall panels, usually of 900-1100 kg/m3, compressive strength - 5-7,5 MPa. Such concrete in construction performs both carrier and heat-insulating function. In a two-or three-layer wall panels required bearing capacity can provide a layer (or two layers) keramsit structural and heat shield - a layer of macroporous insulation keramsit density 500-600 kg/m3.Teploizolyatsionny macroporous claydite - the lightweight concrete, which can be obtained on this filler. Its density at the minimum cement consumption only a little more bulk density keramzite .Na Leca marks 700, 800 receive structural lightweight concrete with a compressive strength of 20, 30 and 40 MPa are used for the production of slabs and coatings, bridge building, where it is particularly important to reduce the weight of structures. Ford Cars understood the implications.

Russian Federation It Absolutely not true. In the online stores sell the same products as in conventional stores, they are subject to the same warranty and they also fall under the Law of the Russian Federation. Price is lower due to savings on rental of retail space. To fully functioning online store requires a website, warehouse and several employees. And the selection of online stores is much greater than in conventional stores. Upon receipt of your order, you get a warranty card and can in case of problems, contact the nearest service center of any manufacturer. Site not fully include the online store. It is rather a showcase site, since the functional site can only view the products and descriptions. Order is not done on the site and by phone. Here is an amateur. Perhaps, after all we will soon see a completely redesigned and multi-engine. Of advantages worth noting a lot of background information. Many interesting can be found, for example, about the city of Penza, historical facts, etc. Here the creators have tried to connect online store and information portal. In any case, "Penza-trade" deserves a solid "four". Second we considered an online store much more interesting, as to the functional and design. This store digital electronics "Technology Penza (www.TehnikPenzy.ru). He was later opened in 2008. In 2010 management decided to completely redo the store management system. In my opinion, is more interesting and more convenient. Now this is really a full-featured online store, which You can see the specifications and product descriptions, photos, read customer reviews.
