Q:Advantages and disadvantages of external formwork and self thermal insulation block
Exterior wall internal insulation technology, wall insulation is to heat insulation materials 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 existing buildings of energy-saving transformation, especially at present when the house sold to individuals, the whole building or the whole district unified transformation difficulties, only the possibility 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 insulation layer destroyed after use of cement paste and tiling
Attach tiles directly to the insulating layer. But one requirement is to check the insulation process in the balcony of your house. Usually wall - insulation layer - galvanized wire mesh - cement mortar, scraping - paint. If the lack of process fill such as galvanized mesh, remove paint, and tiling. You can use high mark cement or direct adhesive.
Q:Difference between inorganic insulation material and organic thermal insulation material
1, organic insulation material with light weight, good processability, high compactness, good insulation effect, but the disadvantage is: aging resistance, deformation coefficient, poor stability, poor security, easy combustion, ecological environmental protection is poor, difficult construction, construction cost is higher, and the limited resources. It is difficult to recycle.2, inorganic insulation materials with energy-saving, waste, heat insulation, fire protection, antifreeze, anti-aging and excellent performance, as well as low prices and other characteristics, can achieve A-level fire protection, has a wide range of market demand.
Q:What are the bubble bricks?
(non autoclaved aerated block equipment), wide range of technical uses. Using this technique, the mold can be used for producing hollow block, insulating brick, light wallboard and insulation board. It can also be used as lightweight concrete and poured into the insulation fields such as roofing, wall, wall and floor heating.
Q:If there is a main component of cenosphere light insulating brick.
Before 2003 because the price is cheaper to do so cenosphere light heat insulation brick is generally used zeeospheres. After 2003 basically replaced by fly ash and other lightweight refractory material, but some high-grade light brick or floating beads.
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.
Q:Refractory bricks, burner bricks, insulation bricks? Is it a kind of thing?
The burner brick is heavy brick, the use temperature is higher, the insulating brick is light brick, the use temperature is lower than the heavy brick.
Q:What is the price of fireproof insulation material?
Fire insulation materials are various, different specifications, grades of prices are different, according to market rules, there will be fluctuation, the most commonly used are insulation rock wool, insulation board, insulation bricks, fire blocking materials.
Q:What's the price of lightweight refractory bricks?
Insulation bricks according to size, material, performance of different prices are not the same, the same products in different regions also vary slightly
Q:What materials are used for roof insulation
There are two kinds: one is a kind of cotton insulation board, such as rock wool board, aluminum silicate cotton board, but this is not environmental protection, harmful to life, foam board (this fire safety factor minimum), these relatively cheap.
