Concrete foam insulation to warm to warm radiant floor heating is the abbreviation of English as Radiant Floor Heating, based on the entire surface of the radiator, through the radiant floor heating medium layer, uniform heating throughout the ground, using ground heat storage and heat up their own law of radiation conduction from the bottom, to achieve the purpose of heating. Generally use low temperature hot water radiant floor heating body system, as passed down deadening heat, resulting in heat loss, you need to set the degree of hot water pipes beneath warm insulation. Warm insulation foam concrete advantages: 1. Good insulation properties: its thermal conductivity is lower than 0.20W / (mk). 2 high heat. Heat resistant up to 400 ℃ or more, there is no thermal decomposition, will not cause insulation failure. 3 green, non-toxic and harmless. Foam concrete does not contain any toxic ingredients, foaming agent and various additives are not volatile and hazardous substances, is conducive to indoor environment. 4. Carrying capacity. Compressive strength of 0.6 ~ 0.8 MPa, compressive strength is better. 5 using low cost. Styrofoam lower cost than 30% to 40%, with obvious economic advantages. 6 process is simple, fast construction. Smoothing foam concrete pouring can, without laying a sheet, the construction speed faster than polystyrene foam board 1/3. 7 no seams, reducing the joints caused by the heat loss. Warm insulation foam concrete Use: Residential: single-family homes, apartment buildings, office buildings and so on. Public buildings: schools, libraries, hospitals, banks, hall, restaurant and so on. Sports and entertainment facilities: soccer field, gymnasium, tennis court, swimming pool. Industrial Facilities: Factory workshop, factory, baths, insulation and other facilities. Other: greenhouse, botanical garden, transportation facilities, airports and so on. The use of foam concrete characteristics: 1. Light weight: density 160-1700kg/m3 between ordinary concrete 1/5-1/8, are lightweight products that can reduce the building's overall load. (2) Insulation resistance: low thermal conductivity. Thermal conductivity than 0.2w/mk. 3 excellent insulation: compared with the ordinary concrete, have good thermal insulation (0.05kcal/mh. C), is about 20-30 times that of ordinary concrete. 4 of arbitrary strength selected: at any time any configuration needs of the construction, thus forming different intensity, the compressive strength greater than 0.25Mpa 5. Sound insulation: foam concrete can form independent bubbles, sound-absorbing capacity of up to 0.09-0.19% is five times that of ordinary concrete, living space to adequately address the noise problem. 6 strong dispersion: a strong dispersion, to form a uniform foamed independently (0.1-0.3 mm). 7 Low water absorption: foaming foaming tough and independent connection, water absorption at 25% or less. With moisture, impermeability. 8 External forces have upholstered resistance: excellent shock resistance, with the foam concrete products, the formation of numerous independent bubbles, for showing cushions of external force, can disperse to other parts of the pressure to improve the seismic performance. Concrete foam insulation to warm heating and its advantages compared to normal heating mode: 1. Consistent with body heating comfort requirements, so warm from the foot, people will feel warmer and more comfortable. 2 indoor area and space saving, can save to install radiators and heating pipes amount of space, increasing use of an area of ??2% to 3%. 3. allows indoor heating temperature uniformity, to warm at room temperature using a bottom-up evenly distributed air convection weakened, reducing water loss and overcome a radiator heating brings a parched and other deficiencies. 4 heat more extensive selection, you can use underground water, industrial waste heat, heating pipe network, home heating source, etc. 5. Saving money, geothermal radiant heating and other heating methods, energy amplitude is about 20%, if the temperature control device partition, saving rate of 40% can be achieved. 6 increase the thickness of the ground, and has a good sound-absorbing foam concrete action, which has a good floor insulation. Warm main parameters 1. Water temperature: Water temperature of the upper limit of 60 ℃, 65 ℃, 70 ℃, 75 ℃ and so on. (2) Water pressure: 0.3 ~ 0.5Mpa less than 0.8Mpa 3. Supply and return water temperature: supply and return water temperature should be less than or equal to 10 ℃. 4 Water Speed: 0.25 ~ 0.5m / s 5. Foam concrete insulation thickness: 50 ~ 80mm (insulation layer 30 ~ 50mm, the filling layer 25 ~ 30mm) 6. Insulation foam concrete weight: 70 ~ 120kg/m2 7 Ground Temperature control: workers often stay on the ground, should adopt the 24 ℃ -26 ℃, the upper limit of the temperature 28 ℃. Officers to stay on the ground, should adopt the 28 ℃ -30 ℃, 32 ℃ temperature upper limit of the ground without personnel stay, should adopt the 35 ℃ -40 ℃, the upper limit of the temperature 42 ℃. 15136665900 0377-60653331
