• The influence of thermal insulation materials on human health

    In this regard, are particularly harmful diisocyanates. Their allowable concentration in the air at the workplace is 0. V currently produces a significant amount of mineral wool, which finds wide application in construction. On the market there is a large selection of such materials. V past this insulating material is used extensively in the U.? Inache is the case with mineral or glass fiber, manufactured by industry. In case of fire may form highly toxic gases. This also applies to the use of asbestos-cement pipes for drinking water networks. It can be assumed that the glass in this respect luchshe. However, it is safer for health because it contains less fiber, which can cause cancer. 05 mg/m3 of air, and the minimum air exchange equal to 0. AsbestAsbest, being very resistant material, has many technical advantages have been used in various industries. Therefore, you should read them and study their properties in terms of security for zdorovya. In this regard, the authorities were forced to ban n By themselves, these materials are harmless to humans, but after impregnation they can become hazardous to health. They usually have excellent insulating properties and are suitable for use in construction. Isolation of free styrene from polystyrene mass is very small. Carcinogenic properties have mainly fiber thickness of less than 3 microns and a length greater than 5 microns. 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. Some of them are widely used in construction. Due to the exceptional qualities of asbestos fibers – a very high mechanical strength, resistance to aggressive chemicals and high temperatures – in some cases, asbestos is irreplaceable, and therefore allows the possibility of its further application in industry and even in construction, but in much smaller scale than in the past. As a result, often there have been cases of strong, threatening the health of air pollution by formaldehyde in buildings. 5 for an hour and a height of 2. Asbestos fibers in the proportion of these dimensions are very large, and therefore it is very dangerous for zdorovya. Its main component is styrene. S. 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. It can be assumed that the polystyrene is used as a building material, safe for health. 5 m space, you can expect that even use the maximum number of these plates will not lead to excessive air pollution by formaldehyde. Now the situation has changed radically. Insulation materials of vegetable origin in contrast to the above materials and products, plant materials – mainly wood-fiber boards, as well as non-woven fabric or cloth from plant fibers such as Utah, hemp – a little resistant to the biological factors in connection with which they are used after preliminary impregnation of fungicidal drugs. In construction, it can almost completely replace the asbestos volokno. Therefore we can assume that the probability of cancer due to use in the construction of mineral wool is extremely low. In performance is an excellent building material. PolistirolV as insulating materials, especially for reducing heat loss through the exterior building elements, are widely used organic plastic. Crucial to the size and shape of fibers. Mineral wool, glass wool Mineral wool, that is generated by industrial mineral fiber, with properties very similar to asbestos fibers.

    PPLICATION krilamidnogo foam for use in строительстве. In spite of the tolerance for use in construction, polyurethane has negative qualities in terms of health safety. This applies to both asbestos fibers and mineral fibers produced by the industrial method. Studies show that the board allocate a very small amount of formaldehyde, usually less than 0. Used for the manufacture of polystyrene foam does not pose any danger to здоровья. The main fields of application – this is the thermal insulation of walls and ceilings. Unfortunately, its main drawback is the prolonged excretion of free formaldegida. In terms of health safety of mineral wool has two major drawbacks. 05 mg/m3. When the permissible concentration of formaldehyde in the air in a residential area of?
