    In construction, it can almost completely replace the asbestos volokno. When the permissible concentration of formaldehyde in the air in a residential area of? Krilamidny foam all the time there are proposals to use in the construction of insulating foam on the basis of formaldehyde resins. Studies show that the board allocate a very small amount of formaldehyde, usually less than 0. And Canada. 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. On the market there is a large selection of such materials. 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. Therefore we can assume that the probability of cancer due to use in the construction of mineral wool is extremely low. Prepolymers, soft polyurethane resins, hardeners isocyanate is very dangerous to humans. By themselves, these materials are harmless to humans, but after impregnation they can become hazardous to health. 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. Carcinogenic properties have mainly fiber thickness of less than 3 microns and a length greater than 5 microns. Used for the manufacture of polystyrene foam does not pose any danger to здоровья. V past this insulating material is used extensively in the U. There were several thousands of different kinds of products, including well construction components and materials for the manufacture of which used asbestos. However, it is safer for health because it contains less fiber, which can cause cancer. In this regard, are particularly harmful diisocyanates. It can be assumed that the polystyrene is used as a building material, safe for health.

    PPLICATION krilamidnogo foam for use in строительстве. As an example, fiberboard, impregnated ksilamitom. 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. A list of various insulating materials is very extensive. Studies have found that the mineral wool contains a small amount of fibers that may be suspected of carcinogenic action. Polystyrene plates are widely used for insulation of buildings. Mineralnaya wool, as mentioned above, contains phenol-formaldehyde resins, which leads to prolonged release into the environment of free formaldehyde. V present production and use of asbestos declined significantly, mainly due to the reduction of its use in construction. Mineral wool also has excellent thermal and sound insulating properties. As a result, often there have been cases of strong, threatening the health of air pollution by formaldehyde in buildings. Its main component is styrene. 05 mg/m3 of air, and the minimum air exchange equal to 0. 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. S. In terms of health safety of mineral wool has two major drawbacks. Crucial to the size and shape of fibers. It is characterized by considerable stability to high temperatures and chemicals. Inache is the case with mineral or glass fiber, manufactured by industry. 0.

    Effect of. 5 m space, you can expect that even use the maximum number of these plates will not lead to excessive air pollution by formaldehyde. 05 mg/m3. Their allowable concentration in the air at the workplace is 0.
