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:Can fly ash brick keep warm?
Sure, I do fire-resistant insulation bricks, we also use fly ash ah!
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: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:Material and making method of light insulating brick
Thermal insulation brick is a new type of building material synthesized with macromolecule material. 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. Mainly used in toilets, kitchens, television, the background wall, bedroom, walls and so on. And brightly colored, various specifications, can be cut at random, the section neatly.
Q:Is the building built of cement hollow board safe?
The country stipulates that hollow slab buildings can be built at most 7 floors, and of course there are also eleven stories, but these are illegal constructions. More than 7 layers, in the existing architectural design, according to the cement hollow board bearing, there is a security risk;
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:Does the building with the exterior wall thermal insulation brick require adding an angle steel bracket in the middle of the brick?
There is no mandatory requirement, but the thermal insulation system should use expansion bolts to do the pullout test, and the exterior wall tiles also need pullout tests.
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:Is sintering insulation brick good or concrete porous brick good?
Strength and fastness are, of course, porous bricks.
