Q:What is the concept of lightweight refractory material?
Lightweight refractory material has high porosity, mechanical strength and erosion resistance. Compared with normal refractory bricks, it is a kind of refractory material with large volume shrinkage in high temperature, low thermal conductivity and small bulk density. It is used as thermal insulation material in industrial furnace and other thermal equipments. It has poor wear resistancel.
Q:Who knows what is the requirement for fireproofing of interior decoration materials ?
In addition to the underground building, combustion performance level of interior decoration materials inside windowless room , in addition to a class, should advance 1 level based on the original provisions . Library, archives and rooms storing artifacts, ceilings, walls should use class A decoration materials, and the ground should use decoration materials no lower than class B. When high temperature parts of lighting and lighting lamps and lanterns are close to non - grade A decoration materials should be taken, fire prevention measures such as thermal insulation and heat dissipation must be taken. Combustion performance level of materials used for lighting should be no lower than B. Kitchen ceiling, wall and floor should used class a decoration materials.
Q:Who knows about the fire endurance of sintered shaly hollow bricks?
1. after roasting at high temperature of more than 1200 degrees, shale burned bricks in construction works can be free from expanding with heat and contracting with cold. 2. masonry walls can be plastered with no needs of any anti-cracking, reinforcement measures, and walls will not bulge and crack, which can reduce the construction cost, as well as are preferred building materials of frame structural engineering. 3.They have good sound insulation and thermal insulation performances, are one of the green building materials that the state currently promotes. 4. They have high intensity. The average compressive strength of them is up to 15.8, which matches with M7.5 cement mortar that has advantages of low water absorption, and good anti efflorescence performance.
Q:Who can tell me what is neutral refractory?
Refractories mainly refer to aluminum oxide, chromium oxide and carbon as the main component of refractory materials, such as corundum brick, high alumina brick, and carbon brick. Its characteristic goes to the resistance to both acidic and basic slag. Basic refractories mainly refer to the refractory materials whose mian components are magnesium oxide and calcium oxide, including magnesia bricks, magnesia-alumina bricks, magnesia chrome bricks, dolomite bricks, etc. Basic refractory is good at resisting basic slag erosion.
Q:Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?
You can add some animal hair, like bristles. After all, we don’t have so much hair. Remember not to use cement, because it will crack. Instead, make use of animal hair, lime, yellow mud and sand, after mixing up, and they would be firmer while in calcination.
Q:What materials is silicious thermal insulation board made of?
Refractories that contain more than 93% of the monox are acidic refractory materials which include ordinary silica brick, high-density and high-purity silica brick, silica brick that contains chromium, fused quartz products, unburned brick and siliceous ramming materials. It has good softening temperature under a fixed load and can resist corrosion of acid slag, but will have chemical reaction with alkaline slag. Silicious refractory of industrial value mainly is crystalline quartz, such as α and β quartz, tridymite and cristobalite.
Q:What are the types of advanced refractory?
Divided into ordinary and special refractory two categories. Common refractories by chemical properties into acidic, neutral and alkaline. Special refractory are divided by the high temperature oxide, refractory compounds and high-temperature composite materials by its compositions. according to refractoriness it can be divided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and premium refractory products (2000 ℃ above). The article can be divided into blocks (standard bricks, shaped bricks, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminosilicate, zirconia and boron carbide quality, etc.) and irregular shape (refractory clay, pouring materials and ramming mixes, etc.) According to the sintering process is divided into sintered products, cast products, melt blown products. The appearance is shaped or amorphous according to pH it can be divided into acidic, neutral and alkalinity according to basic operation mode, there are castable refractory ramming spraying materials, impressionable plastic material, coating. according to different components, there are clay, high alumina, corundum, spinel, magnesia, magnesium, calcium, magnesium aluminum quality,magnesia-chrome, silicon, etc.
Q:Is the ball mill used in production of refractories?
It depends on what refractory you produce.
Q:who knows the requirements of refractory for forge furnace?
Here is the requirements of refractory for forge furnace: according to the chemical properties,casting fireproof materials are divided into three major categories: acidic, neutral and alkaline refractory materials. alkaline and neutral refractory materials are commonly used, such as alkaline magnesia-carbon bricks and burned magnesite bricks, magnesite-chrome bricks, magnesium-calcium brick, neutral high alumina brick, corundum brick, clay brick, etc., shapelessness materials include: castable refractory, ramming mass, gunning mix, coating, dry vibrating materials and so on! Hope my answer can help you.
Q:How long is the fire endurance of fire resistant rolling shutter door?
According to the requirements of Building Regulations 7.5.1 article,the fire endurance of class A fire resistant rolling shutter door should be no less than three hours.
