Q:What are the types of building blocks?
1. the use of the different parts, building bricks into bricks, floor brick, brick, brick arch shell, brick brick chimney and sewer.2. different building performance, building bricks into bearing brick, brick, brick, non bearing engineering insulation brick, brick, tile, acoustical tile and other flowers.The use of 3. different materials, is divided into building brick clay brick, shale, coal gangue brick, fly ash brick, slag brick, lime sand brick etc..4. according to the shape, the building brick can be divided into solid brick, microporous brick, porous brick and hollow brick. Ordinary bricks and special-shaped bricks, etc..
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 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:Masonry method for boiler refractory brick
Masonry of furnace bottom:(1) the bottom shall be leveled before masonry; when the masonry is made, the walls around the bottom shall be first laid, and the height shall be approximately higher than the surface of the hearth. Then the bottom horizontal line (for example, multi layer masonry, together with the layer line) is marked on the straight wall, and then the bottom can be built.(2) when the bottom is made of multi layer bricks, the masonry shall be carried out by layer by layer, and the upper, lower and the same floor shall be staggered. The long side of the surface brick shall be vertical to the direction of the flow of slag or gas.(3) the high temperature area and the furnace bottom which need to be frequently repaired must leave the expansion gap at the bottom of the furnace and the straight wall, and the asbestos rope or asbestos board will be embedded in the gap.
Q:The project cost in hydropower No.3 shaft wall is solid brick or insulating brick?
Aerated concrete for external walls is to save money. One side is the outer wall.. Solid bricks are the first thing, safety comes first.
Q:Coke burns in a closed house. Will anyone suffocate in it?
Coke incomplete combustion can produce colorless gas carbon monoxide toxic odor. Carbon monoxide is a harmful gas. It will enter the body in the blood and hemoglobin, hemoglobin can combine with oxygen, cause the body tissue hypoxia, which causes the body to suffocation.
Q:Which kind of balcony heat preservation material is better?
New inorganic insulation material, this material thickness is thin, in 2-3 centimeters line, direct smear on the top of the house, without auxiliary materials, the price is higher than rock wool, aluminum silicate cotton.
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.
Q:Are there any construction waste materials for composite thermal insulation bricks?
Material production of ordinary light insulating brick clay, high alumina high strength low iron bead brick, mullite, high aluminum light insulating refractory brick, diatomite insulating refractory brick.
Q:What is the bulk density of insulating bricks?
Stoneware porcelain water absorption rate is greater than 0.5% and less than or equal to 3%; fine stoneware bibulous rate is greater than 3% and less than or equal to 6%; brick bibulous rate is greater than 6% and less than or equal to 10%; pottery tile water absorption rate is greater than 10%. The water absorption rate of expression: ceramic brick brick >6% = >10% = >3% = fine stoneware porcelain stoneware or porcelain >0.5%
