Q:Is sintering insulation brick good or concrete porous brick good?
Strength and fastness are, of course, porous bricks.
Q:Can fly ash brick keep warm?
Add blocks and have autoclaved fly ash bricks, do not you?
Q:Masonry method for boiler refractory brick
In accordance with the construction procedure of from bottom to top, from the inside to the outside of the drum and the lower part of the principle of convection tube flame plate concrete when the interval is from top to bottom.
Q:What's the difference between refractory bricks and insulating bricks?
As far as we are concerned about the characteristics of refractory bricks and thermal insulation bricks, refractory bricks are sure to be aimed at fire resistance, while insulating bricks are more focused on thermal insulation. And more specifically, let's take a look at the following parameters.
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:Can activated carbon be antiseptic?
In addition to activated carbon carbon, also contains two kinds of admixtures: one is the combination of chemical elements, mainly hydrogen and oxygen, these elements are due to incomplete carbonization and the residue in the carbon, or in the process of activation, non carbon and activated carbon surface chemical foreign combination, such as the use of water vapor when activated, the surface of the active carbon is oxidized or water vapor oxidation; another kind of admixture is ash, it is part of the inorganic carbon in ash; activated carbon is easy to cause two pollution.
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:How to do indoor thermal insulation
Soft packing can also achieve warmth effectTry to change the interior decoration style, whether in visual or make new home warm, in all senses such as the fabric furniture instead of wood or iron rattan furniture, or the use of fabric material packaging wood seat, living room, bedroom stone and tile carpet, lighting equipment can be replaced with warm light lamp. Wall hanging tapestry. When choosing curtain, choose the curtain with thick cloth, thick, insulated and warm effect as much as possible. In addition, the cold tone leather sofa "cotton": a soft warm cotton sofa is the inevitable choice, also can make full use of cotton cushion and pillow.
Q:What bricks are thermal insulation bricks?
Insulating bricks, a new type of product that can replace tiles, are mainly used in toilets, kitchens, TV sets, bedrooms, walls and so on. And brightly colored, various specifications, can be cut at random, the section neatly.
Q:What is the price of refractory bricks
Insulating brick is a refractory brick often used in kilns to reduce the heat loss of kilnsSo as to ensure the practical efficiency of kiln and bring more benefits.There are many kinds of thermal insulation bricks, and there are many refractory manufacturersAs to how much bricks should be paid, a detailed consultation should be made to the refractory bricks manufacturerHave some understanding of the properties, technologies, raw materials and so on, and make a decisionDifferent types of insulation brick prices are different, the price is relatively cheap, lightweight clay insulation brick 1The market price is 1.3 yuan a pieceThe price of mullite heat preservation brick 0.8, the market price of 4.62 yuan a pieceDepending on the area, the price of insulating bricks will fluctuate somewhat
