Q:For refractory, what is critical particle size? Thank you.: Critical granularity means the maximum size of particles in refractory.

Q:Which brand of refractory fiber hard thermal insulation board is better?: Luyang ceramic fiber semi-hard board is good for it has typically applied major technological performance industrial furnaces backing, wall lining, lining material, electric heating furnace backing lining heat insulation ceramics shuttle kiln, backing lining of tunnel kilnand roller kiln.

Q:How to choose thermal insulation materials for flood heating?: By controlling the foaming ratio, nucleating agent size, moudle pressure, temperature of screw, vacuum foaming technology, extruded sheet of different density can be made. The density of commonly used plastic extruded board is 25-50 kg per cubic meter. Plate density is the main factor affecting the cost of the extruded plate. The higher the plate density, the higher the cost price. Plate density is the main factor affecting the cost of the extruded plate. The lower the density of extruded board, the worse quality performance. Plate density of common plastic extruded is between 30 to 38 kilograms per cubic meter. The density of plastic extruded plate of exterior wall is between 30-35, if the density is too low, then the plate will not be strong enough, if high, flexibility of plastic extruded board will be inadequent, unable to bear the stress brought by housing settlement deformation, resulting in cracks in the wall. With the extrusion plate for floor heating should be in 36 kilograms per cubic meter. If it is too low, ground subsidence will occur due to the low strength, resulting in the ground crack. If density is too high, the thermal conductivity coefficient will increases, impacting energy saving. High density extruded plate is generally used for occasions having special requirements for compressive. Parking lot roof should use extruded plate above X350, whose density is 40 kg per cubic meter. The aircraft need to use the Ping extruded board above X500, density in 45 kilograms per cubic meters. High speed railway subgrade need to use extruded plastic board above 700KPA,

Q:How long usually will the A-level fireproof materials prevent the flame?: Having a fire resistance test on any building components -----according to the standard time-temperature curve. This period starts from the time when affected by fire and ends up with losing the ability to support or to insulate fire or the integrity of the components. It can be expressed in hours. A-level fireproof materials can last for 2 hours.

Q:Concrete composition and function of magnesia bond used in refractory: The first answer is 2 points, and the answer is accepted. You get a reward and 20 bonus points. Magnesia, magnesia brick, magnesia brick, magnesia brick, magnesia calcium brick, magnesia carbon brick

Q:What are Grade-A waterproof inorganic thermal insulation materials?: Grade-A waterproof inorganic thermal insulation materials include: 1. external wall thermal insulation materials: (1) silicate thermal insulation material (2) gelatine powder polyphenyl granule (3) steel wire gauze picking cement cystosepiment (Estazolam plate) (4) extruded sheet; 2. roofing materials: (1) XPS Extruded sheet (2) EPS cystosepiment (3) perlite and perlite bricks (4) vermiculite brick; 3. heating and air conditioning material: PUR, rubberplastic sponge, polystyrene foam, glass wool, rock wool; 4. steel structure material: polystyrene, extruded board, polyurethane board, glass wool roll mat, etc.

Q:what is the Specifications Grading for Fireproof rubber insulation materials ?: External insulation materials, welded wire mesh matt external wall insulation, external wall thermal insulation mesh matt. 1,inorganic activel thermal insulation materials 2,silicate?thermal?insulation?material 3,ceramic thermal insulation 4, gelatine powder polyphenyl granule, 5,teel wire gauze picking cement cystosepiment（Estazolam platepowder particles)6 extruded sheetXPX. 7,Rigid polyurethane coating at the scene, Polyurethane insulation board8,rigid polyurethane foam,9EPS foam board roofing materials. 1, a ceramic insulation board 2, xps extrusion board 3, perlite and perlite brick 4, vermiculite and vermiculite brick heating, air conditioning Material: Phenolic resins, polyurethane waterproof thermal insulation integration, sponge rubber, polyethylene, polystyrene foam, glass wool, rock wool Steel material: Polystyrene, extruded sheet, polyurethane panels, glass wool carpets and the like. Five inorganic thermal insulation materials: Foam cement, DY inorganic active insulation system super thin vacuum insulated panel for building external walls .

Q:Urgently!! Refractory problems, online, etc.: The service life of most refractory materials is a pair of contradictory effects. As a result, one aspect of the contradiction is porosity, and the other is volume density. The larger the volume density is, the smaller the porosity is and the more erosion resistant, but the thermal shock effect is very poor. The bigger the porosity is, the smaller the volume density is, the better the thermal shock effect is, but it is not resistant to erosion. More professionally, two curves should be made to find the intersection of the curves to adjust the recipe and production process

Q:How long does it take for refractory cement to solidify?: 1. First you should be aware of the concepts of condensation and condesation time. Refractory cement belongs unshaped refractories, which when added water or liquid binding agent to mix, the agitation material will gradually lose thixotropy or plasticity and become in a state of solidification, thus is solidified. The time needed to finish the process is called solidification time. The whole process is divided into initial and final set. When beginning to lose plasticity called the initial setting, when called plasticity completely lost the final setting. 2. For refractory cement, the solidification time depends on the matching of the material and the parts and using methods. Under normal circumstances, in order to meet the requirements of time of construction, the initial set time should be no shorter than 40min, and the final set time should be no longer than 8H 3. There are also some exceptions. When refractory cement is used for spraying and injection operation together with other refractory castable, the set time is required as short as possible, sometimes flash set is required to prevent the occurrence of peeling or collapse of the spraying layer.

Q:Who knows what fire heat preservation material are there?: Organic material, polystyrene board, plastic extruded board, phenolic resin. Sea capacity module (fire insulation materials fire performance can reach the B1 level, thermal conductivity is only 0.028w\m - K is a good choice, class A fireproof materials now is the mainstream rock wool (mineral wool is wool). A1 fire resistance The largest manufacturer is Thai stone rock wool Co. Ltd.
