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 can introduce the difference between galvanized fireproof?coatings and steel structure fireproof materials?
Steel structure with heat galvanization has a process requirement, which is to spray fireproof coatings. Fireproof coatings have different functions and purposes from galvanized process. When the steel surface derusted, it generally needs to brush rich-zinc primer before spraying fireproof coating. Fireproof coating plan itself includes anticorrosion plan, and fireproof coating is just a layer of coating plans, which is an intermediate layer in general. Fireproof coating plan generally includes primer, fireproof coating and finishing paint. Some fireproof coatings can be directly painted on the bare steel elements without primer and finishing paint.
Q:What refractories can withstand high temperature above 2100 degrees?
But the price is more expensive, while the insulation performance is not as good as common materials. Is there a material that can withstand 2100 ℃? Currently, the long-term use temperature of the best refractory bricks is about at 1800 ℃, while materilas that can withstand a temperature of 2100 ℃ are relatively rare in the production.
Q:Who knows the refractoriness of high temperature lightweight firebricks?
Hefei Jiu oak decor help you answer; the biggest feature is refractory: refractoriness 700.
Q:The classification of fire-resistant material
There are various refractory materials classified according to the chemical properties of material: Min< manufacturing technique: neutral refractory materials, pipes, etc. Standard model: baidu.hiphotos;8 simatic carbon composite refractory material zirconia based refractory material special fire-proof material 6; or a acute angle of 50~70° and material forms. 3.
Q:What are the raw materials of refractory?
Of course, different types have different raw materials: Magnesite (the electric?smelting: alkaline refractory, magnesia-carbon bricks, alkaline, high-purity) + crystalline flake graphite + phenolic resin + additive (silicon powder, aluminite powder, silicon carbide powder, or high-temperature asphalt,etc.) , acidic refractory: The neutral is not easy to answer. such as. You can check out the classification, such as
Q:Can anyone say something about the curtain wall fire-proof material key sealing point?
Hello. 1. Gaps between the curtain walls and floors of all tier and partitions outer edge should be sealed with non-combustible material or flame retardant materials. Filling material can be rock wool or mineral wool, whose thickness should be not less than 100mm and should meet the designed fire endurance requirements, forming fire and smoke prevention areas between floors and rooms. Fireproof layer should use galvanized steel bearing with thickness of not less than 1. 5mm, and should not use aluminum plate. Gaps between bearing plate and main structure, curtain wall structure and the bearing plate should be sealed by fireproof sealant; fireproof sealant should has fireproof inspection reports granted by statutory testing organizations. 2. When building designs requiring transparent effect of fire compartment and separation, monolithic fire-resistant glass or hollow and laminated fire-resistant glass nade by monolithic fire-resistant glass can be adopted. 3. Windowsills-free curtain walls, incombustible entities skirt wall or fireproof glass wall whose fire endurance is not less tan 1.0 hour and height is not less than 0.8m should be set on the outer edge of each floor. The thickness of reinforced concrete floor or height of the side beams should be counted when calculating the height of the skirt wall. 4. Fire protection layer should not contact directly with the glass curtain wall, and the side towards the glass of fireproof materials should be covered with the decorative material. 5. Glass units of the same curtain wall should not cross two fire?compartments.
Q:How many grades of fire?rating are there for interior decoration materials?
It can be divided into structural material and base?material based on materials. It can also be divided into flammable, flame retardant and non-combustible materials based on fireproof types. There is no fire?rating for materials. But lengths of time of flammability limits are different.
Q:What is the function of refractory material?
Refractory is a basic material in the field of high temperature technology. Generally, the refractory is used as structural material or lining to resist high temperature in various thermal equipment and high temperature container. In the iron and steel industry and metallurgy industry, coke ovens are mainly composed of refractory materials. Various refractories that meet the requirements are essential in blast furnace for ironmaking, hot stove, all kinds of steel-making furnaces, soaking furnace and heating furnace. Not only the die casting for molten steel needs lots of refractory materials, but also the continuous casting needs some high-quality refractory materials. Without high-quality refractory materials, external refining is also not impossible to achieve. Statistics show that the steel industry is the sector that needs the most refractory. Pyrometallurgy and thermal processing of ferrous metal also needs refractories. All high-temperature furnaces or lining in construction materials industry or other high temperature industries that produce silicate products such as glass industry, cement industry, and ceramics industry must be constructed with refractory materials. All kinds of roasting funaces, sintering funaces, heating furnaces, boilers, flues, chimneys and protective layers in chemical, power and machinery manufacturing industry need refractories. In short, when some kind of structures, devices, equipments or vessels are used under high temperature, they all should utilize refractory to resist the high temperature because those materials will deform, soften and fuse or will be eroded, scoured or broken due to the physical, chemical, mechanical effects, which may stop the operation, affect the production, contaminate processed objects and impact the quality of products.
Q:What are the technical requirements for refractories?
To put it simply, physical indicators are pores, volume density, pressure resistance, slag resistance, thermal shock resistance, foot expansion coefficient, thermal conductivity, oxidation resistance and so on. If it is castable, the indicators are mobility, water rate, setting time, and anti bending strength. If it is coating mix, the bonding strength should be checked. Chemical indicators are loss of ignition and the content of aluminum, magnesium, silicon, calcium, chromium, titanium and carbon.
