Q:Can activated carbon be antiseptic?
Activated carbon is also called activated carbon black. It is black, powder or lump, granular, cellular amorphous carbon, and also arranged crystal carbon.
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:What are the specifications of high strength diatomite insulating bricks?
Exterior wall insulation decorative board insulation performance is very good, and the processing method, anchor node and patent products cold bridge design reduces the energy loss, therefore, especially in the area of bad weather such as the northeast, northwest and other places, energy-saving insulation requirements are very high, the traditional thermal insulation construction has brought great difficulty to the construction.
Q:Difference between inorganic insulation material and organic thermal insulation material
The main difference between inorganic insulation materials and organic thermal insulation materials is that the types of insulation materials are different:1, inorganic insulation materials, including glass wool, rock wool, expansion perlite, micro nano insulation board;2, organic insulation materials are mainly polyurethane foam, polystyrene board, phenolic foam and so on.
Q:What is the price of refractory bricks
The refractory insulating brick generally refers to light brick, normal furnace lining are using this brick kiln will not increase the weight, and good heat insulation effect and ordinary insulating brick production are made of clay, high alumina high strength low iron bead brick, mullite, high aluminum light insulating firebrick, diatomite insulating refractory brick, the use of light heat insulation brick can increase the use of the area, at the same time, good insulation effect, in the hot summer, the temperature of the furnace using solid clay brick and low 2-3 ~ C, reduce the power consumption. The construction is superior, the light insulating brick has good machinability, and the construction is convenient and simple, and the labor intensity can be reduced, the construction efficiency can be improved, and the construction period can be shortened. The price is determined by the choice of material and volume density, from several hundred to 5000 yuan, mainly with the choice of material
Q:Clay insulation bricks insulation, brick and ordinary clay brick, fireclay, brick distinction, and its use? Thank you
The insulation brick integrates the excellent heat preservation effect into the wall while building the wall. Low thermal conductivity, high strength, durable, lightweight, simple construction, easy handling, economy, green environmental protection, sound insulation, fire protection etc..
Q:What bricks are thermal insulation bricks?
Thermal insulation brick is a new type of building material synthesized with macromolecule material. Grey, hollowed out bricks are basically.
Q:How much is a thermal brick
If you really want to buy thermal insulation brick, do not simply look at the price, but also to consider the quality of the product. (a piece of brick in the market basically in 6 yuan, if there is a floating price if it is because of the size of the insulation brick or distance, but floating slightly.)
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:Why does the water drop first and then rise when the boiler fires?
This is the reason for the zero water level gauge line below the center line of the drum. Under normal conditions for water and evaporation is balanced, after the fire, reduce the amount of steam water mixture into the drum in the evaporation decreased rapidly, reduce the volume of water bubbles, sudden contraction, drum water level decreased rapidly. But not to water change or increase (automatic), water balance is broken, the water level will rise rapidly.
