Q:What are the sizes of lightweight thermal insulation bricks?
The production of material ordinary lightweight insulating refractory brick with fireclay and high alumina high strength bead brick
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:Can fly ash brick keep warm?
Add blocks and have autoclaved fly ash bricks, do not you?
Q:How to reinforce a porous brick foundation?
Enlarged section method: it is used for the relatively shallow foundation with independent depth, strip foundation, raft foundation, box foundation and pile foundation applicabilityPoor.
Q:What is mullite insulation brick?
According to the application temperature can be divided into: 1350 mullite bricks, 1450 mullite bricks, 1550 mullite brick etc..
Q:Advantages and disadvantages of wall insulation system?
The advantages of external insulation: external wall insulation is one of the most scientific and most efficient thermal insulation energy-saving technology, is outside the insulation material in the main enclosure structure, which can not only achieve the purpose of thermal insulation, but also protect the main structure of the building, and prolong the service life of buildings. This technology can solve the problem of energy loss in the two seasons of winter and summer indoor temperature due to the large, represents the direction of development of energy saving technology. The system does not produce thermal exterior insulation construction, so it has good energy saving effect. In winter, when the indoor heat through wall insulation materials will be effectively blocked, thereby reducing indoor heat consumption; summer, wall insulation materials will also prevent solar radiation and external heat into the room, and in the building to create a cool and comfortable environment.
Q:What's the difference between refractory bricks and insulating bricks?
In the preferred insulation performance, the thermal conductivity of insulating brick insulation 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. In the degree of refractoriness, the refractoriness of insulating bricks is generally below 1400 degrees, while the refractoriness of refractory bricks is above 1400 degrees. In density, insulation bricks are generally lightweight insulation materials, the density is generally in 0.8-1.0g/cm3, and the density of refractory bricks are basically above 2.0g/cm3.
Q:Is it necessary to abolish the technical regulations for the construction of self thermal insulation masonry building with sludge sintering insulation bricks?
The original "technical specification for self insulation masonry building with silt insulation bricks" has been replaced by DGJ32/TJ78-2009 (technical specification for automatic insulation wall system of sintered silt non bearing insulating brick) DGJ32/TJ78-2013.
Q:What is the function of insulating bricks? Where can I use it?
Thermal insulation bricks are mainly used in toilets, kitchens, TV sets, bedrooms, walls and so on. And brightly colored, various specifications, can be cut at random, the section neatly.
Q:What's the price of lightweight refractory bricks?
In addition, general price comparisons are meaningless and need to be based on the use of demand = quality of products. After all, good quality is the driving force of continuous production.
