F240 Finer	60-82	≥5

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's the varieties of fire-proof?sealing?material?: Fire blocking material currently on the market include: fire stopping board, foam blocking material, flame resisting module, fire-resisting sealant, flexible organic caulking, WXY-II and fire retardant bag, etc. fire-proof?sealing?material is widely used in building construction and can ensure high-temperature flame and smoke from fires not spread to another fire?compartment, different buildings generally use different sealing methods. Pipeline is generaly sealed by pouring concrete board or mortar.

Q: In entering fire door, which material does well?: About this, I personally advice you to take a look at the building materials market, where will be many options and comparativity would be much better.

Q: How long is the duration of fire resistance that fireproof door of level B can endure?: According to the duration of fire resistance, fireproof doors can be divided into three levels, namely level A,B,C. And accordingly, the duration of fire resistance of them should not lower than 1.20h, 0.90h and 0.60h. Fireproof door, a door that can meet the requirements of fire resistance stability, fireproof door integrity and thermal insulation at a certain time, is a fireproof separator which is located in fireproof partition, emergency staircase and vertical silo. Apart from functioning as a common door, a fireproof can also prevent the spread of fire and smoke in a certain period to make sure that people are safely evacuated.

Q: What's the refractory material in common use currently?: According to its category, raw material of basic refractory: Mainly magnesite (magnesia), dolomite, lime, olivine, serpentine, high alumina material (sometimes neutral); main neutral raw material: chromite, graphite, silicon carbide (artificial).

Q: What are the common refractory insulation cotton material?: I know less about this, I hope the following will help: Fire resistant thermal insulation material mainly refers to inorganic thermal insulation material and compround thermal insulation material. According to the shape can be divided into: Fibrous finishes, slag wool, rock wool, glass wool, aluminum silicate cotton. ceramic fiber, micro pile of diatomite, calcium silicate, expanded perlite, expanded vermiculite, aerated concrete etc., foam like bubble glass, volcanic ash glass, foam clay, foaming concrete, paste powder polystyrene particles insulation slurry

Q: What kind of foundry ingot refractory materials are there? Please be more detailed.: This question is a little bit extensive, because there are too much foundry ingot refractory materials.

Q: What are the main characteristics of the sic refractories?: 1. The usage temperature of silicon carbide refractory is generally 1760 ℃ 2. The silicon carbide refractories can withstand dramatic changes in temperature, and a good thermal shock resistance performance. To prevent the cracking or breaking of lining refractories. 3. Under the conditions of high or low temperature, it can withstand a certain compressive stress. 4. Under the conditions of high or low temperature, it can withstand friction. 5. It can withstand the huge hydraulic pressure or buoyancy of the metal. 6. It can also withstand the effect of furnace gases to prevent the infiltration of other refractories and reactions.

Q: What is fire retardant coating mainly used for?: Fire retardant coating is a coating which is applied to the surface of buildings and structures and can form a protective layer of fire retardancy and thermal insulation. It can reduce the flammability of the coated materials and block the rapid spread of fire so as to improve fire endurance of the coated materials. Features of fire retardant coating: (1) Fire retardant coating itself has a flame-retardancy or non-inflammability, and it can prevent the protected substrate from direct contact with the air, and delay ignition and reduce the burning speed of the objects. (2) In addition to flame retardancy or non-inflammability, the fire retardant coating itself has a a low thermal conductivity, which can delay the transfer of flame temperature to the substrate to be protected. (3) When heating, fire retardant coating decomposes non-combustible inert gas to dilute the combustible gas decomposed by the protected, making it difficult to burn or slow down the burning rate. (4) Fire retardant coating containing nitrogen will decomposite NO, NH3 and other basic groups, which compound with the organic radicals and interrupt the chain reaction so as to reduce the temperature. (5) intumescent fire retardant coating will expand and foam when heating, and form a carbon foam insulation to block the protected objects, thus delaying the transmission of heat to the substrate.
