The blocks in the two types of "flammable" and "inflammable" are on the market. The weight of each piece of cement blocks used in construction, 15 kg, while the weight is minimal Yonolit blocks and large size would bring down the weight of the building.
However, under the cover of fire on the surrounding blocks, in the event of a fire in the building, these blocks are only 20 minutes withstand heat. Safety homes against fire and accidents, including safety issues that should be considered urban. In many cases the safety of a building material that can be used as one of the most noted.
Blocks "Polystyrene" due to its light weight, the final weight of the building are low, so are used in construction. Do not block the reproductive role and therefore safe against earthquakes.
If the quality of the blocks used in construction, will be more resistant to fire. Iran is not only the type of building materials used, but also numerous other building materials that do not meet the mandatory standards and is also used in construction. Due to the crisis our country is rich in the building blocks should be used flammable and non-flammable blocks are limited by rules to fire wide of the buildings have been averted. Storage krakatoa foam of these materials as well as the responses that may be very dangerous and has witnessed some of the blocks have a warehouse krakatoa foam fire.
Interestingly, these blocks and mentality contrary to some experts, the lack of integration of the percussion have a positive effect on the picture in sound reinforcement sound absorbing Hstnd.yvnvlyt good impact sound insulation better than concrete and is not a And for that reason alone Yonolit no effect on the loss of sound. According to experts only if the double wall Yonolit used, noise reduction increases. Sound insulation and thermal insulation are not alone and if they get into the system, they can reduce the sound.
Polystyrene foam products of the petrochemical industry and the appearance of fine crystal, which expands the vapor pressure in the vicinity of the closed cell structure of the polystyrene blocks and the water Yonolit the resistance growth of corruption and to protect the development of the petrochemical industry today our beloved homeland witnessed increasing variety of applications in different fields are petrochemicals. EPS material is very high style with functionality and its people make the mistake of rubber (a natural substance), (Kachv) or (Yonolit) call.
EPS is an example of the kind of material called expanded polystyrene and EPS known symbol and numerous applications in packaging, insulation, training, advertising and so on. These materials with fine and coarse grain size and weight of the granules, sheets and blocks of different sizes and thicknesses packaging in number, is available. Hot or Hot Wire Cutting wire also available in the market, in various shapes and designs becomes.
This polymer is styrene monomer. Therefore, it is very clear characteristics of crystalline polystyrene. Haqh density of the benzene molecule attached to the main chain to prevent large structural order and makes them become amorphous in nature. According to the polystyrene glass transition temperature of polystyrene plastics is much higher than normal krakatoa foam temperatures useful. This feature makes it incredibly hard plastic and slightly fragile. Fragile, transparent and polishing and density of 09/1 - 04/1 g / ml is. About 90% of light to pass through the normal and proper material to produce synthetic glass and windows in the room are closed.
6 ml of distilled water and calcium chloride 75/0 ml of 10% over 30 minutes by gradually separating funnel to add balloons. This leads to the formation of calcium phosphate krakatoa foam Ghml that used to play in the monomer. Then add this mixture into a water bath at 90 C and the temperature of the heater and let us hold fast the magnet to the end of the reaction. 10 ml distilled Mvnvmrasyvn 4/0 g benzoyl peroxide was added and then dissolve the mixture to a separation funnel add 10 minutes to the mixture. After two hours of polystyrene produced on a Buchner krakatoa foam funnel and washing with water or hydrochloric acid straightened 2% at 40 C dry ironing.
About 97 percent of the volume of air trapped between the cells EPS EPS, which makes it an excellent insulation and light arise. (Air insulation is one of the best) and the reason for the insulation of buildings against heat, cold and noise from the EPS used and the style and hit the best budget options
