- 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: Who knows the fire rating of fire?partition with steel stud?
- 1 hour. It is in line with the fireproof test standards of national building materials . CaSo4.2H2O is molecular structural formula of gypsum which contains 20% water, crystal water and free water. When 10% water slowly evaporates on the flame surface, there is still 10% crystal water. Itself is grade A fire retardant material. It can reach up to four hours at most.
- 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: Does anyone know what is a lightweight refractory material?
- Heat preservation and insulation layer used only for Thermal Equipment has poor wear resistance, loose organization and high porosity(40%~85%) . The definition of light refractory material: low thermal conductivity, good performance in thermal insulation , weak mechanical strength, low volume density(generally below 13).
- Q: What are fire?ratings of wall thermal insulation material?
- 1.thermal insulation material with grade A combustion performance: YT inorganic active insulation material for wall thermal,rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2.thermal insulation material with grade B combustion performance: Extruded polystyrene board(XPS)after special treatment/polyurethane(PU) after special treatment, phenolic aldehyde,gelatine powder polyphenyl granule, etc. 3.thermal insulation material with grade B2 combustion performance: Molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc.
- Q: what should be paid sttention when buying the refractory?
- solve the resources and the cost as much as possible. Accurate understanding and knowing the material temperature changes of various partsin order to choose the appropriate refractories. 4： 3, work performance, for example, take measures to ensure the overall life, and it is a very good buying principles: melting in high temperature metal erosion. These are the four major problems to consider when using refractory. You can choose low prices and low transportation costs of materials to meet the basic principles under the conditions described above. 2.carefully observe the material to prevent the desturction and reducing the costs. according to the structure of furnace, reasonable coordination of all parts of the material, fully take the advantages of material characteristics and strive to develop the recycle, to avoid the destruction of the materials.1. the working characteristics and the sport condition and analyze the reason of destroying the material, which can not only gurantee the product quality and reduce the expenses, get familiar with the chemical component and physics of the material.
- Q: what is the material of fixed first rate fire resistant window?
- Window frames and fireproofing glass, fire sealing strip, fireproofing glass mound layer, which is infexible fan, and the flexible fans have to plus folding and closing window cleaner. (3) window frames must be integral with the building, using wood or iron to connect the wall. After the installation of the steel frame, the cement mortar must be watered between the window frame and the wall, and it should conserve more than 24 hours before normal use.
- Q: What is neutral refractory? Can refractory suppliers tell the main components of it?

- Q: Are the rubber insulation materials are refractory materials?
- It's not.
- Q: How to divide fire resistant level of fire door?
- Fire resistant level of fire door【Class A fire door】. Class A fire door is also called complete fire door. It can meet the requirement of fireproof thermal insulation and refractory integrity at the same time in specified time. Fire resistant levels are 0.5h(Grade C), 1.0h(Grade B), 1.5h(Grade A) and 2.0h, 3.0h. 【Class B fire door】Class B fire door is also called part heat insulation fireproof door. Its requirement of fireproof and thermal insulation performance is 0.5h. Refractory integrity levels are 1.0h, 1.5h, 2.0h and 3.0h respectively. 【Class C fire door】Class C fire door is also called not thermal insulation fireproof door. Ther is no requirement of its fire resistance and thermal insulation. It only meets the requirement of refractory integrity in specified refractory time. The grading of refractory integrity is 1.0h, 1.5h, 2.0h and 3.0h respectively. There is the content of not thermal insulation fire door in British BS standard.
