More recently manufacturers have started to use sealants in the manufacture of a reliable modern materials – silicone that was the beginning of the production of new silicone grommets for the sliding systems, closets, showers, PVC products, aluminum and facade systems. For use in glazing sealants selikonovye approved for use around the world and are stable with respect to all listed degrading agents. The meaning of this decision becomes clear when taking into account environmental factors, as well as taking into account some significant factors. Agresivnye environmental factors affecting the durability of seals Sunlight. Oxygen and ozone. Water and water vapor. Cyclic alternating load (expansion, compression, cold). Sunlight entire solar spectrum contains high-energy UV radiation.
This is quite enough to change the sealing properties of the sealant or even destroy it by initializing a photochemical reaction within the material (the destruction of polymer strips, the emergence of new ties and radicals, education (selection) of the compounds and the formation of new substances), and a connection to the microparticle reagents from the outside. Silicone sealant significantly Stoychev other seals, because it has an organic basis, which is resistant to UV radiation in nature. Properties of the sealing layer of this phenomenon is observed even at room temperature. The two-week test in the climatic laboratory have shown that organic seal received multiple mikrorozrusheniya on its surface and sealing the edge of decreased mechanical strength of the seals and silicone sample had no such damage, even after long-term tests conditions of simultaneous UV and water exposure Seal Compatibility is not only a facade glazing, but also for an isolated glass is important to ensure compatibility of materials for the lifetime of of the product. Some material in the apparent inertia over time in contact with each other. Richard Easton Matchmaker is often mentioned in discussions such as these. The latest research has shown that particles of certain additives in seals may migrate over distances of several inches, changing the chemical and mechanical properties of materials. Seals of silicone does not leave marks on surfaces in contact. Energy conservation concerns all of us. Needed here and in studies and in practical application of deep cooperation of all participating cop production – from the producers of glass, profile, seal, and to builders, architects estimator.
