Q:Advantages and disadvantages of external formwork and self thermal insulation block
Exterior wall sandwich thermal insulation technology, the exterior wall sandwich insulation is placed between the inside and outside wall panels of the outer wall, and the inner and outer wall can be made of concrete hollow block.Advantage:1) the inner wall film and insulation material form effective protection, the material selection of heat insulation material is not high, polystyrene, glass cotton and urea formaldehyde on-site pouring material can be used;2) the construction season and construction conditions are not very high, and it does not affect the winter construction. In Heilongjiang, Inner Mongolia, northern Gansu and other cold areas have been given some applications.Shortcoming:1) in non cold areas, this kind of wall is thicker than traditional wall;2) the inner and the outer wall pieces need to be connected by connecting pieces, and the structure is more complicated than the traditional wall;3) periphery structure of "bridge" more. In the earthquake zone, building circle beam and constructional column settings, "bridge" more efficiency of thermal insulation materials is still not fully play.4) outside the walls by the outdoor climate, the temperature difference between day and night and the large temperature difference between summer and winter, easy to cause the wall cracking and leakage of rainwater.
Q:The structural specification does not indicate that masonry needs insulation bricks. Is it necessary to use insulation bricks?
Under normal circumstances, the use of thermal insulation brick experience in construction drawings marked, if there is no relevant description requirements, then do not use insulation bricks.
Q:Difference between inorganic insulation material and organic thermal insulation material
Manufacturing distinction:1, organic insulation materials mainly from petroleum products, including foam polystyrene board (EPS), extruded polystyrene board (XPS), spray polyurethane (SPU) and polystyrene particles. From a nationwide perspective, the organic exterior wall insulation system occupies more than 75% of the current external thermal insulation Market in our country.2, inorganic heat preservation material including expanded perlite, hollow glass beads, rock wool, mineral wool, perlite, glass wool and lightweight block self insulation system, mainly based on inorganic materials such as stone, glass, industrial waste and so on. As the state attaches importance to and requirements of the fire protection safety standards for wall materials, the market share of inorganic thermal insulation materials will be greatly improved.
Q:What are the new types of building brick materials?
In addition to the original clay brick, other masonry materials seem to be called new materials. Sintered silt bricks, steam blocks, lightweight blocks, hollow clay bricks, etc..
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:How to do indoor thermal insulation
Basic decoration, can make indoor insulation work, such as some specific practices: when laid wood floor, the grille can be in the floor of the placement of insulation materials, such as mineral wool board, flame retardant foam etc.. In the custom doors, may require manufacturers with glass wool or mineral wool insulation materials etc.. To install windows and doors are sealed, if the window is the original single ordinary window glass, then the best decoration for hollow glass broken metal windows, can also use light decoration patent products: multifunctional solar heating refrigeration air conditioning doors and windows, doors and windows. Live in the top floor of the residents, but also in the ceiling when placed on the gypsum board insulation materials, in order to improve insulation. If the original wall has internal insulation layer, be careful not to destroy when decorating. If the design is to open the balcony and living room, it is necessary to install the insulation layer on the wall and top surface of the balcony.
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:Does the building with the exterior wall thermal insulation brick require adding an angle steel bracket in the middle of the brick?
The first thing the man has to do is to do the quality test in front of the wall. As for the second, there is not much to do.
Q:What is the thermal insulation performance of aerated bricks?
Aerated brick light weight, heat preservation, heat insulation, sound insulation, easy processing, using a variety of hybrid material production, rich production of raw materials, especially the use of fly ash, and comprehensive utilization of industrial waste, environmental pollution, saving farmland, have a good social and economic benefits, is an alternative to the traditional solid clay brick ideal wall materials. Gongyi Machinery Factory is specialized in producing aerated brick equipment manufacturers.
Q:What is the bulk density of insulating bricks?
National classification standard: water absorption rate of ceramic tile is less than or equal to 0.5%;
