• The influence of thermal insulation materials on human health

    May 1

    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. Mineral wool, glass wool Mineral wool, that is generated by industrial mineral fiber, with properties very similar to asbestos fibers. 05 mg/m3 of air, and the minimum air exchange equal to 0. Studies show that the carcinogenic mineral fibers are almost independent of their chemical composition. Studies have found that the mineral wool contains a small amount of fibers that may be suspected of carcinogenic action. 4-2. In performance is an excellent building material. In this regard, the authorities were forced to ban n V present production and use of asbestos declined significantly, mainly due to the reduction of its use in construction. However, widely used by only some of these materials, and therefore should pay attention on their strengths and weaknesses in the security aspect for zdorovya. Now the situation has changed radically. 5 for an hour and a height of 2. They usually have excellent insulating properties and are suitable for use in construction. This also applies to the use of asbestos-cement pipes for drinking water networks. However, it is safer for health because it contains less fiber, which can cause cancer. Their allowable concentration in the air at the workplace is 0. V past this insulating material is used extensively in the U. The main fields of application – this is the thermal insulation of walls and ceilings. PolistirolV as insulating materials, especially for reducing heat loss through the exterior building elements, are widely used organic plastic. It is characterized by considerable stability to high temperatures and chemicals. AsbestAsbest, being very resistant material, has many technical advantages have been used in various industries. Krilamidny foam all the time there are proposals to use in the construction of insulating foam on the basis of formaldehyde resins. 02 mg/m2 surface of the plate for 1 hour. In this regard, are particularly harmful diisocyanates. As a result, often there have been cases of strong, threatening the health of air pollution by formaldehyde in buildings. Polistirol plastic mass. As an example, fiberboard, impregnated ksilamitom. In construction, it can almost completely replace the asbestos volokno. Similar properties are fiberglass. People show great ingenuity in this field. By themselves, these materials are harmless to humans, but after impregnation they can become hazardous to health. The reason for this was lack of knowledge of carcinogenic asbesta. Multilayer exterior walls or walls of cold storage also often contain polyurethane foam. 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. Unfortunately, its main drawback is the prolonged excretion of free formaldegida. Crucial to the size and shape of fibers. Polystyrene plates are widely used for insulation of buildings. And Canada. Its main component is styrene. One faction of mineral fibers contained in the mineral wool, carcinogenic, and the binder used in the production of mineral wool – phenol-formaldehyde resin or melamine – in a long time allocates free formaldehyde, which is highly toxic, carcinogenic and suspected in Asbestos fibers in the proportion of these dimensions are very large, and therefore it is very dangerous for zdorovya. ПенополиуретанЖесткий foam also is widely used in construction. Mineralnaya wool, as mentioned above, contains phenol-formaldehyde resins, which leads to prolonged release into the environment of free formaldehyde.
