• The influence of thermal insulation materials on human health

    Dec 13

    AsbestAsbest, being very resistant material, has many technical advantages have been used in various industries. As a result, often there have been cases of strong, threatening the health of air pollution by formaldehyde in buildings. He even used to manufacture toys, pipes, and a dust mask. This also applies to the use of asbestos-cement pipes for drinking water networks. In this regard, are particularly harmful diisocyanates. 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. However, it is safer for health because it contains less fiber, which can cause cancer. In terms of health safety of mineral wool has two major drawbacks. Multilayer exterior walls or walls of cold storage also often contain polyurethane foam. Isolation of free styrene from polystyrene mass is very small. Studies show that the board allocate a very small amount of formaldehyde, usually less than 0. 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. 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 performance is an excellent building material. Crucial to the size and shape of fibers. It can be assumed that the glass in this respect luchshe. It can be assumed that the polystyrene is used as a building material, safe for health. It is characterized by considerable stability to high temperatures and chemicals. When considering the problems of building in the security aspect of health must be to draw attention to the widespread lack of acoustic insulation of building walls.

    PPLICATION krilamidnogo foam for use in строительстве. They usually have excellent insulating properties and are suitable for use in construction. Therefore, foam should not be used in large quantities in buildings. More… Above the main shortcomings of housing was due, primarily, the lack of appropriate market insulation. 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. As an example, fiberboard, impregnated ksilamitom. Prepolymers, soft polyurethane resins, hardeners isocyanate is very dangerous to humans. V present production and use of asbestos declined significantly, mainly due to the reduction of its use in construction. Harmful properties of asbestos are manifested only when asbestos fibers are included in the products and materials into the air and then penetrate the human respiratory system. The reason for this was lack of knowledge of carcinogenic asbesta. Carcinogenic properties have mainly fiber thickness of less than 3 microns and a length greater than 5 microns. S. Now the situation has changed radically. 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. V past this insulating material is used extensively in the U. In case of fire may form highly toxic gases. Therefore, you should read them and study their properties in terms of security for zdorovya. Polystyrene plates are widely used for insulation of buildings. Inache is the case with mineral or glass fiber, manufactured by industry. Mineral wool also has excellent thermal and sound insulating properties. In this regard, the authorities were forced to ban n PolistirolV as insulating materials, especially for reducing heat loss through the exterior building elements, are widely used organic plastic. 5 m space, you can expect that even use the maximum number of these plates will not lead to excessive air pollution by formaldehyde. Mineral wool, glass wool Mineral wool, that is generated by industrial mineral fiber, with properties very similar to asbestos fibers. Polistirol plastic mass. In spite of the tolerance for use in construction, polyurethane has negative qualities in terms of health safety. There were several thousands of different kinds of products, including well construction components and materials for the manufacture of which used asbestos. This applies to both asbestos fibers and mineral fibers produced by the industrial method.
