Q:What is the price of concrete self insulation bricks
Insulation brick prices also have a great relationship with the material and workmanship, such as clay brick price is much lower than high alumina brick, mullite and corundum brick prices will be higher.
Q:The insulation layer destroyed after use of cement paste and tiling
Put on the insulating layer and paste it with cement.Some students worry about the insulation layer and the wall adhesive strength is not enough, do not worry about, now developers are building exterior insulation and then on top of the tiling. Because after finishing the insulation layer, the contractor should check the construction to do a pullout test, the purpose is to prevent the strength can not meet the requirements.
Q:Coke burns in a closed house. Will anyone suffocate in it?
Coke combustion, can produce carbon dioxide gas released into the atmosphere can increase the concentration of carbon dioxide in the atmosphere, the greenhouse effect is getting worse, a series of harmful to human disasters occur more frequently. And too much carbon dioxide inhalation can cause hypoxia, inhibition of the respiratory system, causing death.
Q:Outside brick wall, inside brick wall how to return a responsibility?
In general, the wall of the building and outdoor harsh environment, so the general exterior wall tiles with full ceramic tile surface, then is the kind of uneven, and the appearance of the size deviation of brick is relatively large.
Q:What material is good for indoor thermal insulation?
Own home, if the south, hot summer and cold winter zone, with inorganic insulation mortar or polystyrene particles insulation mortar, the effect is very good;
Q:Are there any differences between insulating bricks and refractory bricks
The insulation performance of thermal conductivity of insulating brick in general 0.2-0.4 (average temperature 350 - 25 DEG C) w/m.k, and the thermal conductivity of refractory brick in 1 (the average temperature of 350 - 25 DEG C) above w/m.k, which can obtain the insulation performance of insulating brick than refractory brick insulation performance is much better.
Q:Masonry method for boiler refractory brick
Furnace wall gas tightness requirements, gray seam fullness requirements: red brick is not less than 85%; refractory brick not less than 90%. When the red brick is built, the method of squeezing is adopted, and the construction of the refractory brick is constructed by scraping.
Q:What is composite sintering insulation bricks?
Taking the Yangtze River, lake and silt as the main raw materials, the performance indexes of roasting are in line with the technical specifications and technical requirements of the building blocks, referred to as insulating bricks.
Q:Insulation brick should pay attention to external walls?
Construction at room temperature, 24h after spraying water conservation, water spraying should not be too much, not flow. Unsuitable for winter construction. According to the national standard, seven consecutive days and nights, the average temperature is less than 5 degrees, may not carry on the external wall insulation, brick construction.
Q:What is a heat insulating brick?
Thermal insulation brick is a new type of energy-saving building insulation technology with inorganic composite material as the main material. It is an ideal technology to replace the traditional wall insulation.
