Q:What is the difference between the fire?rating and the fire resistant level of the fire-fighting equipment?: Hello there. Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. As for the warehouse building "category malonate", it refers to one of the fire risk of goods storage, which is divided into A, B, C, D, E, and each category is refined depending on the nature of different substances. "Malonate class" specified in article 3.1.3 of "building design for fire protection" refers to the flammable solid.

Q:What is the requirement of refractory concrete for raw materials? What is the main principle of commercial mixing station?: Commodity concrete stations can not be produced in general, and are made by professional fire resistant concrete manufacturers.

Q:How to distinguish between class A fire resistant door and class B fire resistant door from appearance ? What are the differences between the two refractories? Thank you !: It is difficult to distinguish from appearance. Their fire endurance are also different. The filling refractories of grade A and Grade B fire resistance steel doors are all perlite. The only difference lies in the filler compaction density.

Q:Does anyone know what is the use of waste refractory materials?: 1.Waste refractory bricks can be reused to make the refractory bricks after being crushed by crusher, but the price is not very high. The purchasing price of refractory plant is ?60/ton. Because the refractory material has been calcinated for two times, it becomes easier to make bricks expansion coefficient with waste refractory bricks, but too much is inadvisable. If too much, the refractory materials would have a bad combination, which will give rise to loose bricks and incomplete corners. Nowadays, ordinary refractory plants would purchase waste refractory bricks to produce bricks, but better plants wouldn’t do this.

Q:Ask some questions about refractories: Is a kind of refractory material, jargon called hook materialThe iron runner: a combination of the super high Los resistant technology, aluminum and corundum, silicon carbide and other raw materials, to high-quality composite binders and additives, strict proportioning, elaborate. The utility model has the advantages of good slag resistance, good thermal shock resistance, long service life, convenient use, simple construction, and obvious reduction of labor intensity of workers.Application: it is suitable for blast furnace tapping system.

Q:Are refractory materials and fireproofing materials the same?: Refractories are generally used in the industry such as power plants, electric stove and industrial furnace. They include refractory bricks and insulation materials. Fireproof materials are generally used in building and they are fireproofing.

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 are the chemical composition of refractory cement?: Calcium aluminate prepared by calcining as the main component. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement.

Q:Can anyone tell me what material the first rate fire resistant door is?: Material of Class A fire doors mainly are steel, wood, steel and wood, and other materials. Fire door is one of the measures of the building fire separation, usually used on the firewall, entrance and exit of staircase or tube well openings, which is required to hane the abilities of smoke insulation and fire insulation. Fire door plays an important role in prevention of the spread of smoke and fire and the reduction of fire loss. Therefore, we must have strict requirements. Fire doors are divided into class A, class B and class C, whose properties of fire-resistant thermal insulation and fire-resistant integrity should be no less than the following values: Class A should be1.50h; class B should be1.0h; Class C should be 0.5h. - stipulations in article 4.5.1.2 in "The New Standard of Fire Doors" GB12955-2008. I hope my answer can help you. Thank you.

Q:How to measure the influence of high-temperature performance of the products refractory in the formation of the liquid phase.: Generally how can do high-temperature performance to measure how much liquid may affect hot bending strength rul refractoriness levels of high temperature creep?
