Hydrogen

The reason for such diversity is the difficulty of the problem of fire protection of wood material, and with the possibility of variation in a wide range of substances contained. That's why, when choosing the best flame retardant should take into account a number of features. Fire retardant impregnation should not increase the hygroscopic properties of wood or degrade its mechanical properties must be safe for humans and animals, shall not release harmful substances after application. Typically, flame retardants used to impregnate wooden structures operating in conditions precluding direct and prolonged exposure to moisture. In this regard, on the market are mostly washed out and legkovymyvaemye funds for water-based. For outdoor use they are used in combination with subsequent paint layer.

The necessary condition is the absence of their negative influence on the adhesion of coatings. When selecting fire-resistant impregnation should pay attention and concentration index Hydrogen ion – pH of the medium. For example, there are flame retardants with pH = 1,5, close to the pH of strong acids. The use of such funds is not safe for the consumer and requires careful observance of the special conditions storage and use. Many flame retardants, have significant corrosion aggressiveness towards how to color and for black metals. In some cases this may limit their use. For example, there are cases where the use of fireproof materials with high pH leads to the destruction or deterioration of the roof made of copper or galvanized metal.

Some flame retardants provide control toning timber. This allows you to visually assess the quality and uniformity of application of flame retardant. For example, the famous composition " ognebio TRAC" gives wood a pink tint, and can quickly adopt and control the results of flame retardants work. Some formulations can be tinted immediately before use, and some require the use of well-defined colors. RezultatyPri all, it would seem complexity and confusion fireproof timber should say straight out that the ultimate goal of this work is not the preservation of the primordial form structures. The main objective of fire protection is the security people so that they confidently out of the affected buildings, and that they had confidence in a happy outcome. Is not that a successful outcome?

Laminated Glass

Double glazing triplex – a combination of two layers of glass with a special interlayer. As a third bonding layer using a transparent film of plastic or hardened fluid. For the production of laminated use of glass of various kinds: 1. Patterned. 2. Enamel. 3.

Float glass. 4. Tinted in the mass. 5. Tempered. 6. Heat-saving.

7. Reflective. Double-glazed windows with laminated glass system is one of the best options high impact and safety glazing. Wide variety of colors inside the film between the layers can decorate any space, guided by their own preferences and requirements of the common design. By Compared with conventional plastic window glazing application of this type has many advantages: * increase the breaking load on the glass 60-80% * no metal fragments in the event of damage to the glass (They remain on the crimping bed) * improved sound and heat insulation; * Ensuring high degree of safety (the production of bulletproof windows) * high optical transparency of the glass; * resistance Scratch * color stability; * protection against ultraviolet and infrared radiation. Types of triplex structures as the main indicator of laminated glass is their thickness, calculated by formula: S = S1 + bb + S2, where S1, S2 – thick glasses, short-circuit – the thickness of the bonding layer (usually up to 1.5 mm). According to the method of production, depending on the type of laminated glazing interlayers can be of two types: 1. Film Here 3 millimeter layers of interconnected polymer film thickness of 0.38 mm, 0.76 mm or 1.52 mm. Such glass sheets are made available size the following types: * fireproof * architectural * color * bent. 2. Jellied Layers insulating glass units are connected by a polymer laminated stock. Structural thickness varies depending on its purpose and mode of operation. They can have any thickness, since the number of the filling polymer is not limited. Laminated glass can be used: * for registration lobbies and entrances to public buildings; * Installation of office partitions * in the double-glazed windows, situated on the roofs of buildings; * at glazing stops complexes, sports halls, schools, kindergartens and shopping centers * for laying glass floors and stair treads; * the glazing of greenhouses, museums, banks, * as a wind motor glasses.
