Q:What is the interior fireproof thermal insulation material?
Polystyrene board, extruded sheet and polyurethane are mainly used. Polystyrene board is the cheapest, but the thermal insulation effect is ordinary. When absorbing water, it will deform. Other waterproof measures are needed to be made after insulating layer is done./
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 can refractory material of the electric furnace be used for longer.
I do not know if you are referring to super high power arc furnace for steelmaking, if you are, I have a easy solution for I have been doing this work.
Q:What are included in roof thermal insulation fireproofing material?
Aluminium foil, bubble, aluminium foil/air bubbles/fireproofing aluminium foil thermal insulation material, fireproofing bubble thermal insulation material, fire retardant thermal insulation material, thermal insulation construction materials, aluminum foil insulation material.
Q:What is shapeless refractory with high performance?
The popular ones are: Non-cement fine powder bonded castable is a functional refractory castable with nano material introduced.
Q:About the use of horseshoe glass kiln refractories
the lower portion of advanced clay brick, the lower portion of magnesia-chrome brick arch - high-purity silica brick; flue - clay brick; breast wall--33 # fused zirconia corundum brick (with shrinkage); fused zirconia bottom --33 # fused zirconia corundum brick (with shrinkage); regenerative chamber- the upper part of sintered magnesia-chrome brick, cooling section 33 # electric smelting no shrinkage fused zirconia corundum brick; the wall - the melting section 41 # no shrinkage fused zirconia corundum brick (including 41% of zirconium; the lattice- superstructure of high purity magnesia brick, the same below); small stove --33 # fused zirconia corundum brick (with shrinkage). It can be said that it is the maximum configuration, if the funds is limited it can be downshift appropriately.
Q:What are the models of bauxite with high alumina?
China Ferrous Metal Industry Corporation released the industry standard of bauxite (YS / T78-94) in 1994. According to this standard, bauxite can be divided to sedimentary diaspore, stacked type diaspore and lateritic gibbsite. According to the chemical composition, it can be divided into nine trade marks as LK12-70, LK8-65, LK5- 60, LK3-53, LK15-60, LK11-55, LK8-50, LK7-50 and LK3-40. In addition to the provisions of chemical composition of bauxite, the standard also requires that the water of sedimentary diaspore shall not exceed 7% and water of stacked type diaspore and lateritic gibbsite shall not exceed 8%. Moreover, particle size of bauxite should be not greater than 150mm. Bauxite shall not be mixed with clay, limestone and other debris.
Q:What material is used for making refractory stone bowl?
It is attractive and diverse in appearance, hard, and heat fast, not stick food when using. The cooked food is attractive and delicious and rich in various trace elements which is beneficial to the human body. It is also of high quality, and all these make it popular among the customers.
Q:How is the grading of the level A new material fire insulation material?
The standard to distinguish level A and level B is the different fireproofing coefficient. The level A is non-combustible. The level B is divided into B1, B2 and B3. B1 is flame retardant, B2 combustible and B3 flammable. The level A is commonly phenolic aldehyde, rock wool, thermal mortar, foam ceramics, foam glass and foam concrete on the current market. Among the advantages of level A materials, the biggest one is foam concrete currently, also known as foam cement.
Q:Does anyone know about the A-level fireproof materials?
A1-level fireproof materials include: 1. inorganic materials: glass wool, rock wool, foam glass,etc. 2. organic materials: phenolic foam insulation composite board. I hope my answer can help you.
