Suspended Ceilings

Different types of suspended ceilings are increasingly used for decoration in homes and in offices, shops, restaurants, entertainment centers, warehouses, factories etc. Apart from the attractive appearance, they have a number of advantages over the plastered and whitewashed or painted slabs. High moisture resistance, good noise absorption, ease of maintenance and long life – this is far from complete list of advantages suspension systems. Among the reasons why consumers choose this type of ceiling, quick installation, the ability to install lighting fixtures of all types and hide the failed communication – posting Duct ventilation systems and others. One of the types of suspended ceilings are dlinnopanelnye cassette. For even more analysis, hear from Futurist. They are made of metal and have a coating of the protective and decorative functions. Thanks modern technologies of production, each magazine has strict geometric dimensions to ensure smooth joints, and perfectly smooth surface, which guarantees the attractive appearance of the ceiling. Use as a material galvanized steel 0,6 mm thick aluminum or 0.7 mm allows finished products to avoid deformations in the transportation and installation, and gives them the necessary strength when embedded lamps various types and ventilation equipment.

Provided retention system can withstand not only the weight of the tapes themselves, but also additional equipment. In addition to the smooth models are produced and perforated with holes round and square shapes, and diamond – in the panels, known as "shtrekmetall design. Dlinnopanelnye cassette of this design allow for better ventilation: this is particularly important in public areas with high level of traffic.

NTDs Analysis

To establish the type of material used and the quality of fire-retardant coatings using methods of thermal analysis. The essence of the method consists in comparing the curves thermogravimetric analysis and significant thermoanalytical characteristics (identification parameters) of the samples of coatings (sites with fire-retardant-impregnated) with a "benchmark" data. Under the "reference" refers to the data presented in the technical documentation on the production of flame retardants are scanned or received at the primary testing (test reports) of the samples retardants and materials. Compared subject thermoanalytical characteristics and parameters obtained only when completely identical conditions on the instruments of one class of accuracy. Simply speaking, every material has a set of thermal analysis curves and parameters unique to its formulation. Experimentally established that any, even minor changes in formulation of the material entail changes in the thermal analysis curves and identification characteristics. On this application and is based experimental method of thermal analysis to identify materials in the tests on the fire hazard (fire-retardant efficiency) and quality control of flame retardants work.

fgu emercom Russia has accumulated great experience in the identification of substances and materials by thermal analysis. Published guide 'Identification of solids, materials and tools for fire protection tests for fire hazard ', which are described in detail the procedure for preparing samples for thermoanalytical studies, the technique of thermal analysis and comparison of the thermal analysis curves and establishing identity. The Institute has a data bank which contains identification features more than two thousand substances and materials. For quality control of flame retardant impregnations responsible parameter is Kosovo or bottom ash sample. Conclusion of line type and quality requirements of the applicable ptd NTDs also entered in the act of controlling fire protection works. Thus, depending on the quality control tasks on the fire protection facilities may be using the methods of visual inspection and rapid methods of monitoring, measuring the thickness by measuring methods, control of the documentation or through their various combinations. Most complete picture of a fire retardant treatment provides an integrated approach, typically a combination of all of the above methods and methodology to establish type of material used and the quality of fire-retardant coating by thermal analysis.

Sidewalk Slabs

Sidewalk tiles vibrocasting – Concrete mix paving slabs laid in a plastic form. The form of paving slabs placed on vibration table (a table with continuously vibrating surface) and kept at it for some time. Once the concrete mixture in the form of ram, a form of paving slabs removed from the table and stand in warm place about 48 hours, after which it gets from the finished product of the paving slabs. Characterization paving slabs obtained by vibrocasting: Final products have a very attractive appearance and a pleasant smooth surface. Maybe get a huge range of products (a huge range of colors, great selection forms, a variety of surface texture) without extra costs. Due to the high water-cement ratio decreases the final frost products, it needs to be increased with additional cement, expensive modifiers and plasticizers, which increases the cost of products. Vibrocasting technology allows in each case to pick up on request the necessary range of colors, choose the desired shape pavers, and surface structure. Basis Technology – plastic form that is filled with concrete.

Physico-mechanical properties of plastics can give concrete a completely new quality, which impossible to form with other technologies. The texture of the front surface of the product is formed by a high degree of adhesion of plastic and concrete that allows you to create any texture from perfectly smooth to Billing stone broken line. Specially selected composition of plastic attached to form the necessary toughness and ductility at the same time. The number and variety of forms depends on the breadth of assortment and volume of production elements improvement.
