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:There are several construction techniques for exterior wall insulation
Exterior wall insulationSingle material thermal insulation exterior wall: aerated concrete and sintered insulating brickComposite 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: insulation blocks, etc.
Q:Can activated carbon be antiseptic?
Activated carbon is mainly with adsorption properties, there is no direct anti-corrosion effect.
Q:What are the insulation materials for heating buried pipelines?
The heat preservation layer is composed of antirust paint, heat insulating material, moisture-proof layer (used for pipeline in the trench), protective layer, anticorrosive layer (used for trench or directly buried pipe) and top coat (or fireproof coating).The waterproof layer can be used asphalt or aluminum foil protective layer with glass cloth or galvanized steel.
Q:Clay insulation bricks insulation, brick and ordinary clay brick, fireclay, brick distinction, and its use? Thank you
Thermal insulation brick is a new type of energy-saving building insulation technology with inorganic composite material as the main material. It is an ideal technology to replace the traditional wall insulation.
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 material is good for indoor thermal insulation?
Now the main building to do insulation, and generally use benzene board, we do indoor heat preservation is generally used, glass cotton is glass fiber, contact the skin after particularly uncomfortable
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:Which kind of balcony heat preservation material is better?
To environmental protection, then use inorganic insulation materials, such as composite silicate, rare earth insulation, this thickness should be more than 5 cm, the construction of auxiliary materials, high cost, to be strengthened
Q:Are there any differences between insulating bricks and refractory bricks
Heat preservation brick is to emphasize its heat preservation performance generally, not paying much attention to its refractoriness, but refractory brick is exactly the opposite. Different locations will use different materials, I hope we can choose carefully.
