Q: what's the application of fireproofing abs materials?: ABS alloy shell, a toy of child, low load bearing, refrigerator lining, it can be processed into various wear-resisting sheets, plates,and has good electrical performance, it can be used as electronic components or auto parts, all kinds of insulation materials, it's easy to machining on the surface, so it can be made into designated special products (such as electroplate), and easy coloring,

Q: What are grade classifications of the external walls fireproofing material?: 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials.

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 about the performance of aluminum silicate fire proof thermal insulation?: aluminum silicate fire proof thermal insulation board has a good performance. it is a artificial board that separates the wood and plant fiber by mechanical and chemical methods and mixed the adhesion agent and water-proofing?agent, molding by high temperature and high press. the density of fiber. tha above information is coming from the Internet and it is just for reference.

Q: The difference between refractory and thermal insulation material: In simple terms, refractoriness is different. The refractoriness of refractory is high while that of insulation material is low.

Q: What are the differences and connections between softening temperature of the refractory under a fixed load and thermal resistant creep property of the refractory?: The result of refractoriness under load is temperature while the result of creep is percentage of deformation. Refractoriness under load and creep can be tested by an instrument. Refractoriness under load reflects the temperature in which the deformation reaches a certain degree under the condition of load. Creep reflects the deformation refractory has under the condition of constant temperature and load. Both refractoriness under load and creep are important criterion for the operating temperature of refractory.

Q: What is the type of heat resistance property of high temperature electric furnace ?: According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃

Q: How long is the fire-resistant time of fireproof wooden door?: fire endurance class A (1.5 hours), class B (1.0 hours), class C (0.5 hours).

Q: What does refractory mean?: Ordinary refractories are often used brick, semisilica brick, clay brick, high alumina brick, magnesia brick etc..Special materials often use AZS brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Often used insulation refractories are diatomite products, asbestos products, insulation panels and so onUnshaped refractory materials commonly used are fettling, refractory ramming material, refractory castable, refractory plastic material, refractory clay, refractory gunning, refractory cast material, fireproof coating, lightweight castable, mud etc..

Q: What is the limit of fireproof rolling shutter?: According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: According to provision 14102-2005 GB: If fire resistance limit of fire resisting shutter is no less than 3 hours, it is AAA fireproof rolling shutter. Therefore, the fire resistance limit of AAA grade fireproof rolling shutter should be 3 hours.
