Q:What are the sizes of lightweight thermal insulation bricks?
Low iron mullite, high aluminum light insulating refractory brick, diatomite insulating refractory brick. Sizes can be customized for ordinary profiled sizes
Q:Advantages and disadvantages of external formwork and self thermal insulation block
Exterior wall insulation form, single material thermal insulation exterior wall: aerated concrete, sintered insulation brick compound thermal insulation exterior wall:According to the different settings of thermal insulation materials, it can be divided into internal insulation, external insulation and sandwich insulation exterior wall. Thermal insulation decorative integrated board: Other: thermal insulation block, etc..
Q:There are several construction techniques for exterior wall insulation
Exterior wall internal insulation technologyThe interior heat preservation of the wall is to place the heat insulation material on the inside of the outer wall.Advantage:1) waterproof, weather resistance and other technical indicators of finishes and insulation material requirements are not very high, gypsum board, gypsum plaster mortar can meet the use requirement, convenient;2) the internal insulation material is separated by the floor slab and is only constructed within a high storey without scaffolding;3) in the hot summer and cold winter and hot summer and warm winter zone, the inner heat preservation can meet the requirement;4) for the energy transformation of existing buildings, especially at a time when the housing sold to individuals, the whole building (source: China insulation network) or the entire district unified reform is difficult, only by the possibility of a large number of internal insulation. Therefore, in recent years, the exterior wall insulation has also been widely used.Shortcoming:1) because of beam, slab, structural column will cause thermal bridges, more heat loss;2) due to the material, structure, construction and other reasons, the cracking of the facing layer;3) it is not convenient for users to decorate two times and hang ornaments;4) occupy indoor use space;5) the energy saving of the existing buildings is very disturbing to the daily life of the residents.6) wall under outdoor climate, the temperature difference between day and night and the large temperature difference between summer and winter, easy to cause the wall cracking.
Q:The difference between ordinary and diatomite brick refractory brick?
To say the difference, the material is the biggest difference. There are diatomite brick density, compressive strength of small brick kiln belongs to the outer thermal insulation, and heavy refractory brick kilns for multi village in direct contact with the flame, high temperature resistance, good compressive strength, but no insulation. Hope to help you.
Q:What is mullite insulation brick?
Mullite brick, according to different density can be divided into: lightweight mullite brick and heavy mullite brick;
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:Refractory bricks, burner bricks, insulation bricks? Is it a kind of thing?
Not the same thing, refractory bricks and insulation bricks of raw materials, the proportion is not the same. This is the chain of various types of products
Q:What is a heat insulating brick?
The insulation brick integrates the excellent heat preservation effect into the wall while building the wall. Low thermal conductivity, high strength, strong durability, simple construction, light weight, easy loading and unloading, economic, green, environmental protection, sound insulation, fire protection and so on.
Q:What is the thermal insulation performance of aerated bricks?
Dongfeng steam free insulation performance of aerated brick brick production equipment; because the thermal conductivity of foamed concrete block is only 0.21W/M.K, which is 4 times the heat preservation effect of clay brick, cement brick 3 times, so it can improve the living comfort, hot summer and cold winter, can be greatly reduced the running time of the air conditioner,
Q:What is the function of insulating bricks? Where can I use it?
Replace the aluminum plate, honeycomb board, curtain wall and other commonly used decorative materials, multi-functional integration, a construction can solve the thermal insulation decoration two functional requirements, smooth, smooth and beautiful, decorative strong. The utility model has the advantages of high strength, good rigidity, light weight, earthquake resistance, wind resistance, creep resistance, superior performance, lower building load, more economy and durability. Fire retardant, heat preservation, energy saving, sound insulation, heat insulation, crack resistance, waterproof, according to the 65% building energy conservation requirements for construction design.
