Q:Fire rating of decoration materials
All light steel keel gypsum board is considered level A; if the wood finishes up to B2 grade fire rating depends on the proportion of the use of wood veneer and the proportion of this wood veneer fire grade, if the proportion of wood veneer is small,it can be considered level A
Q:How much refractory material is needed when 1 million ton coke oven is produced?
Q:Refractories for iron-making blast furnace?
This question is too professional - as far as I know, there are blast furnace noumenon bricklaying - trough slag runner fire-resistant model ~ main channel carbon rod ~ ramming mixes ~ ~ I do not know the specific details.
Q:How much modulus is used as refractories material of sodium silicate.
Storage and use are very convenient, especially for mechanized and the evenly refractory material and the sodium silicatemodulus is generally...2. transportation. The appearance of product is pure white. Instant powdered sodium silicate, also known as instant sodium metasilicate.4 to 3, in powder form, automation. in the range of 3, hydrated sodium silicate
Q:What do refractory materials include?
It is so difficult.
Q:What are the materials of white firebricks?
They are made of baked refractory materials with pale yellow and a little brown on the surface and very cheap. They are mainly used to pile up smelting furnace and can withstand high temperature from 580 degrees Celsius to 770 degrees Celsius. While the firebricks, also called refractory bricks by others, have a certain size and shape. They can be classified according to manufacturing process, namely, the unburned bricks, burnt bricks and electrically fused bricks. Also they can be divided into common bricks, standard bricks and specific bricks according to different size and shape.
Q:What defect does fused cast refractories have ?
The impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement.
Q:What kind of material is refractory bauxite?
In China it is generally believed: "Bauxite ore refers to the mineral with a fairly high aluminum content (over 40%), and aluminum silicon ratio is greater than 2.5 (A / S≥2.5). Minerals with an aluminum content less than this value is called clay ore or allite shale or aluminious rock. " In China, it has been explored that monohydrate bauxite ore accounts for about 98% of the total reserves of bauxite.
Q:What characteristics do A grade external wall fireproofing material have?
For characteristics of A grade external wall fireproofing material, its main raw material uses cold resistant and thermal insulated, environmental protection and energy saving material with good insulation, keeping the indoor temperature steady and making the environment more comfortable. It is several times better than other masonry in overall strength and resist capability, and it can also hang heavy objects such as air conditioners by directly nailing or installing expansion bolts. Single point hanging machine can withstand heavy objects with the weight of more than 45kg. It can also be directly fixed to the tiles, wallpaper, wooden plaques, paint, etc.
Q:Introduction to refractory material
Refractory material refers to inorganic non-metallic materials with refractoriness of no less than 1580℃. Refractoriness refers to the centigrade temperature of refractory cone sample in the case of no load when resisting high temperature without softening. But the refractoriness alone cannot descript the refractory material, thus 1580℃ is not absolute. Now refractory material is defined as material used in high temperature allowed by its chemical properties. Refractory material is widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate and power industrial area, of which the application in metallurgy accounts for the largest part of 50% ~ 60% of total output.
