• The influence of thermal insulation materials on human health

    4-2. A list of various insulating materials is very extensive. V currently produces a significant amount of mineral wool, which finds wide application in construction. As an example, fiberboard, impregnated ksilamitom. 5 m space, you can expect that even use the maximum number of these plates will not lead to excessive air pollution by formaldehyde. 0. Perhaps even the formation of phosgene. Very polystyrene is widely used because it is fairly durable, non-toxic and is easy deshev. AsbestAsbest, being very resistant material, has many technical advantages have been used in various industries. If these three major blemish housing could somehow estimate the value of residential buildings would have to decrease by about 30%. Therefore, foam should not be used in large quantities in buildings. 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. The reason for this was lack of knowledge of carcinogenic asbesta. However, it is safer for health because it contains less fiber, which can cause cancer. Исследования this material in construction have confirmed the allocation of a significant amount of free formaldehyde. This also applies to the use of asbestos-cement pipes for drinking water networks. In construction, it can almost completely replace the asbestos volokno. Mineral wool also has excellent thermal and sound insulating properties. 02 mg/m2 surface of the plate for 1 hour. Carcinogenic properties have mainly fiber thickness of less than 3 microns and a length greater than 5 microns. This was due to the numerous protests of institutions and individuals involved in the protection of the environment and health. By themselves, these materials are harmless to humans, but after impregnation they can become hazardous to health. Now the situation has changed radically. In terms of health safety of mineral wool has two major drawbacks. It can be assumed that the polystyrene is used as a building material, safe for health. 05 mg/m3 of air, and the minimum air exchange equal to 0. V present production and use of asbestos declined significantly, mainly due to the reduction of its use in construction. PolistirolV as insulating materials, especially for reducing heat loss through the exterior building elements, are widely used organic plastic. There were several thousands of different kinds of products, including well construction components and materials for the manufacture of which used asbestos. Crucial to the size and shape of fibers. ПенополиуретанЖесткий foam also is widely used in construction. On the market there is a large selection of such materials. 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. It can be assumed that the glass in this respect luchshe. They cause allergic reactions and severe forms of respiratory ailments. In this regard, the authorities were forced to ban n It is characterized by considerable stability to high temperatures and chemicals. 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. Asbestos fibers in the proportion of these dimensions are very large, and therefore it is very dangerous for zdorovya.

    Effect of. 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. Polistirol plastic mass. Its main component is styrene. People show great ingenuity in this field. 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. Mineralnaya wool, as mentioned above, contains phenol-formaldehyde resins, which leads to prolonged release into the environment of free formaldehyde. 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. Used for the manufacture of polystyrene foam does not pose any danger to здоровья.
