• The influence of thermal insulation materials on human health

    May 30

    5 m space, you can expect that even use the maximum number of these plates will not lead to excessive air pollution by formaldehyde. He even used to manufacture toys, pipes, and a dust mask. Dolgoe time construction services and facilities that address the fate of housing in this country, one-sidedly focused their attention on the quantitative side problem, neglecting the quality, and only appeared as a result of environmental problems has shown that we can not continue like this housing. 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 V present production and use of asbestos declined significantly, mainly due to the reduction of its use in construction. Furthermore, it should be noted widespread use in residential construction impregnated fiberboards, threatening human health and the development of mold on the walls and ceilings of buildings due to insufficient insulation. Studies show that the carcinogenic mineral fibers are almost independent of their chemical composition. However, it is safer for health because it contains less fiber, which can cause cancer. A list of various insulating materials is very extensive. In construction, it can almost completely replace the asbestos volokno. The main fields of application – this is the thermal insulation of walls and ceilings. 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. In this regard, the authorities were forced to ban n 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. They usually have excellent insulating properties and are suitable for use in construction. V currently produces a significant amount of mineral wool, which finds wide application in construction. Multilayer exterior walls or walls of cold storage also often contain polyurethane foam. Mineral wool also has excellent thermal and sound insulating properties. This applies to both asbestos fibers and mineral fibers produced by the industrial method. 4-2. Therefore, you should read them and study their properties in terms of security for zdorovya. Some of them are widely used in construction. Their allowable concentration in the air at the workplace is 0. This was due to the numerous protests of institutions and individuals involved in the protection of the environment and health. Very polystyrene is widely used because it is fairly durable, non-toxic and is easy deshev. 05 mg/m3 of air, and the minimum air exchange equal to 0.

    PPLICATION krilamidnogo foam for use in строительстве. Studies show that the board allocate a very small amount of formaldehyde, usually less than 0. S. And Canada. People show great ingenuity in this field. Isolation of free styrene from polystyrene mass is very small. Crucial to the size and shape of fibers. Asbestos fibers in the proportion of these dimensions are very large, and therefore it is very dangerous for zdorovya. 5 for an hour and a height of 2. The reason for this was lack of knowledge of carcinogenic asbesta.

    Effect of. Исследования this material in construction have confirmed the allocation of a significant amount of free formaldehyde. In case of fire may form highly toxic gases. 05 mg/m3. More… Above the main shortcomings of housing was due, primarily, the lack of appropriate market insulation. Perhaps even the formation of phosgene. Inache is the case with mineral or glass fiber, manufactured by industry. 0. Carcinogenic properties have mainly fiber thickness of less than 3 microns and a length greater than 5 microns. In spite of the tolerance for use in construction, polyurethane has negative qualities in terms of health safety. On the market there is a large selection of such materials. Mineral wool, glass wool Mineral wool, that is generated by industrial mineral fiber, with properties very similar to asbestos fibers. Therefore we can assume that the probability of cancer due to use in the construction of mineral wool is extremely low.
