The influence of thermal insulation materials on human health

admin, 22 March 2011, Comments Off

Mineralnaya wool, as mentioned above, contains phenol-formaldehyde resins, which leads to prolonged release into the environment of free formaldehyde. This was due to the numerous protests of institutions and individuals involved in the protection of the environment and health. Krilamidny foam all the time there are proposals to use in the construction of insulating foam on the basis of formaldehyde resins. Used for the manufacture of polystyrene foam does not pose any danger to здоровья. Multilayer exterior walls or walls of cold storage also often contain polyurethane foam. When the permissible concentration of formaldehyde in the air in a residential area of? On the market there is a large selection of such materials.

Effect of. It should be added that the so-called samopogasayuschy Styrofoam is not flammable material and the fire highlights the relatively small amount of toxic gases. V past this insulating material is used extensively in the U. Asbestos fibers in the proportion of these dimensions are very large, and therefore it is very dangerous for zdorovya. This also applies to the use of asbestos-cement pipes for drinking water networks. Исследования this material in construction have confirmed the allocation of a significant amount of free formaldehyde. 0. PolistirolV as insulating materials, especially for reducing heat loss through the exterior building elements, are widely used organic plastic. Some of them are widely used in construction. They cause allergic reactions and severe forms of respiratory ailments. Studies have found that the mineral wool contains a small amount of fibers that may be suspected of carcinogenic action. 5 m space, you can expect that even use the maximum number of these plates will not lead to excessive air pollution by formaldehyde. The main fields of application – this is the thermal insulation of walls and ceilings. ПенополиуретанЖесткий foam also is widely used in construction. Similar properties are fiberglass. As a result, often there have been cases of strong, threatening the health of air pollution by formaldehyde in buildings. 4-2. Therefore, you should read them and study their properties in terms of security for zdorovya. A list of various insulating materials is very extensive. They usually have excellent insulating properties and are suitable for use in construction. 05 mg/m3 of air, and the minimum air exchange equal to 0. Given the practical aspect of mineral wool in the building, it is best to use it in the form of plates and laminates, as it facilitates the construction raboty.? In spite of the tolerance for use in construction, polyurethane has negative qualities in terms of health safety. Isolation of free styrene from polystyrene mass is very small. This applies to both asbestos fibers and mineral fibers produced by the industrial method. It should be noted that the experts of the World Health Organization, engaged in harmful effects of asbestos products, are wary of asbestos on exclusion from various areas of application. In case of fire may form highly toxic gases. Studies show that the board allocate a very small amount of formaldehyde, usually less than 0. On this basis krilamidny foam can be used in the construction of buildings from the outside, but can not be used indoors and for people to fill the available space within the walls of buildings. Perhaps even the formation of phosgene. In construction, it can almost completely replace the asbestos volokno. Studies show that the carcinogenic mineral fibers are almost independent of their chemical composition. Polystyrene plates are widely used for insulation of buildings. Prepolymers, soft polyurethane resins, hardeners isocyanate is very dangerous to humans. Polistirol plastic mass.
