Q:What is the use of refractory?
It is used as a protective layer inside the high-temperature, high-corrosion, high-washing, easy to be wore equipment and as an insulation layer outside equipment.
Q:How long is the fire resistance time of the AAAfire resistance rolling shutter door?
How long is the fire resistance time of the AAA fire resistance rolling shutter door?
Q:What are refractory materials?
Refractories can be divided to two categories based on the shape and three categories according to the chemical nature of acidity, neutralily and alkalinity. Alkaline refractory materials are magnesia-carbon brick, magnesia chrome brick, calcium magnesium brick and magnesia-chrome bricks. Neutural refractory mateial are high alumina brick, corundum brick and clay brick. Case-hardened refractory materials are castable, ramming mass, gunning mix, coated mix, dry vibration material, etc.
Q:How many types of special refractories are there?
Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials
Q:how to use boiler fireclay
Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.
Q:who knows the uses of refratories?
1. Category: chinalco refractory aggregate Al2O3 containing about 35% -40%, high-alumina refractory aggregate containing 55% Al2O3. Widely used in thermal equipment, high-temperature furnace wall, heatable brick bed, chimneys, lining and other basic construction, it is mainly used in military, warehouse, air defense, industrial and mining enterprises, and general industrial furnace, the finest raw materials in cement admixture and expanding agent plant. Having a low density, thermal conductivity, water absorption, fire-resistant thermal insulation properties. Lightweight mullite refractory aggregate: This project uses natural materials to synthesize advanced refractory raw materials. It is a new synthetic materials. lightweight refractory aggregate to make lightweight refractory castables at high temperature has been in short supply. In most cases it is replaced by used light weight brick pieces. the entailing problem is : high-temperature lightweight castable refractory shrinks at high temperatures, affecting the performance of high-temperature lightweight castable refractory. high alumina refractory aggregate is often used.
Q:What's the function of aluminium dihydrogen phosphate on the refractories?
Mainly used for binder of high-temperature furnace refractory. Characteristics of liquid aluminum dihydrogen phosphate, castable. solid used for refractory spraying coating, chamotte, ceramic construction, which has high break resistance after being dried in 350-500 ° C, phosphate bricks. Characteristics of the solid aluminum dihydrogen phosphate, binding agent used for castable and casting industry: together with the refractory aggregate, ramming mixes at room temperature: Easy to mix, crush resistance, hydration resistance, chamotte, will not become soft even if soaked or boiling in water, molding. Liquid use refractory spraying coating, mainly used for corundum, chrome corundum water gap in refractory industry. The production of chrome aluminum zirconium corundum brick for water-coal-slurry gasifier is especially suitable for site construction applications mainly used for the electrical industry, high-temperature kiln and furnace, hardener, after mixing between 90-110 ° C for 4-24 hours at a constant temperature, forming strong bonding strength, electrical insulation, heat treatment resistance furnace
Q:Does hardware construction materials contain refractory?
refractory includes one kind of building materials. It is a special material and not commonly used.
Q:Does anyone know what kind of light fireproof materials are there?
二, 1, Gypsum plaster board With the building plaster as main raw material, gypsum plaster board is a kind of processed plate made by a special board for protective with an addition of additives and fibers as board core. Gypsum plaster board is characterized by light weight, sound insulation, heat insulation, strong processing performance and simple construction method. 2, Gypsum block Gypsum block is a kind of lightweight building gypsum product which is mainly made of building gypsum, and by adding water, stirring, casting and drying. During the process, , the fiber reinforced materials or light aggregates are allowed in, and the foaming agent can also be added. It has many advantages, such as sound insulation and fire prevention, convenient construction and so on. It is a kind of new and healthy wall material which produces low carbon, enhances environmental protection, and caters to the the times. 3, Fly ash brick is a new type of wall material, and bulk density is one of the main technical indexes. The weight of bulk density can be controlled according to the need of construction and adjustment of technical formula. The dry bulk density of the fly ash brick is about 1540 to 1640 kg / m 3, slightly lighter than the clay brick (1601800 kg /m 3). The flexural and compressive strength of fly ash brick is mainly determined by the production process, the formula and the hydrothermal synthesis reaction mode as well as the need of construction. According to the standards of architectural material industry (JC239 - 2001) released by People's Republic of China, the average value of the flexural strength is 2.5 ~ 6.2Mpa, compressive strength is between 10 ~ 30Mpa. I hope this will be helpful to you
Q:how long is the fire endurance of plasterboard?
Gypsum board is flame retardant materials, combustion performance rating B1, but when mounted on a steel joist, it can be seen as rating A(non-combustible material) . So it is fine to use as a ceiling. You can randomly choose several samples to run some tests at the quality inspection insititute and the quality of these samples are subject to the testing results.
