Q:How long is the fire endurance of fire resistant rolling shutter door?
According to the new national standards GB_12955-2008 for fire doors from January 1, 2009, fire doors are classified acoording to thermal insulation fireproof door(A),part heat insulation fireproof door(B) and non thermal insulation fireproof door(C), rather than thermal insulation fireproof door. At the same time, the original fire endurances of class A, B and C fire doors are adjusted to 1.5h, 1.0h and 0.5h respectively. So, GB is 1.5h
Q:What things and cement mixed can act as refractory?
Cement building, portland cement, refractory grade, calcium aluminate. Cement acts as refractory need to use calcium aluminate cement.
Q:How many refractory materials does the annual output of 1 million tons of coke oven require?
Refractory materials are expensive, and any refractory accident will lead to a considerable waste of production time and equipment, and sometimes even the product itself. The type of refractory material will also affect energy consumption and product quality. Therefore, it is very important to select the refractory material which is most suitable for various applications. While the economic benefits have great influence, refractory material most suitable for some applications need not be used for materials, but can achieve a balance between material installation cost and performance, this balance is not fixed, but with the introduction of new technology or new refractory materials and changing. History has proved that unremittingly seek metallurgical process more reasonable and development, greatly promoted the development of refractories, quickly resolve these problems has become the modern refractory steel technology development is an important element. The content of this article is to discuss a number of factors including these issues and to provide information on how to solve them.
Q:On the problem of making refractory materials
Refractories mainly depend on their high melting point characteristics. The refractory market is mainly Magnesium Oxide material.
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:Which are fire proofing thermal insulation materials?
Which are fire proofing thermal insulation materials? Which fire proofing thermal insulation materials are commonly seen?
Q:Can someone professionally introduce the classifications of refractories?
It can be divided into two categories of ordinary and special refractory. Ordinary refractories can be devided into acidic, neutral and alkalinee refractories according to chemical properties. Special refractory can be devided into high temperature oxide, refractory compounds and high-temperature composite materials according to the compositions. Furthermore, it canbe devided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and super refractory products (above 2000 ℃) according to the strength of refractoriness. It can be divided into bulks (standard brick, special-shaped brick, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia and boron carbide, etc.) and Indefinite shape (refractory clay, castableand ramming mass, etc.) according to the shapes of products. According to the sintering process, it can be divided into sintered products, cast products, melting jetting products.
Q:what's the detailed address of fireproof and thermal inuslation matertial market?
Following are the detailed addresses of fireproof and thermal inuslation matertial markets: Kunpengyu thermal insulation material co., LTD., Bantian street Daoban xuegang road 1-4, Jindu business building 503, Shenzhen Huameida rubber and plastic thermal insulation material wholesale, Shenzhen Longgang district Nanlian road 7, Nanpeng thermal insulation material Xiangxin road 1-4.
Q:What's the type of fire proofing thermal insulation materials?
Hello! Fire proofing thermal insulation material can be classified as inorganic thermal insulation material and composite thermal insulation material. According to the form, it can be divided into fibrous veneer, mineral wool, rock wool, glass wool, aluminum silicate cotton, ceramic fiber, microporous diatomite, calcium silicate, expanded perlite, expanded vermiculite, aerated concrete, bubble foam glass, ash, glass, clay, foam concrete, and pasted paste powder polystyrene particles insulation pulp, etc. They are characterized by flame retardancy and fire proofing and thus can be used in buildings with high fire proofing class. Among them, calcium silicate, aluminum silicate and asbestos can also be used for the thermal insulation for heat supply pipelines.
Q:Who knows about the criteria of fireproof and thermal insulation materials?
1. thermal insulation materials with A-level combustion performance: EPS sea capacity module, rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. thermal insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), phenolic aldehyde, gelatine powder polyphenyl granule,etc. 3. thermal insulation materials with B2-level combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc. Such A-level insulation materials are only fireproof, the thermal insulation properties are worse than that of organic XPS \\EPS materials. Currently I think that the best insulation material should be EPS sea capacity module, it not only achieves the requirement of insulation but also fulfills the goal of fireproofing, and the comprehensive unit price of it is not expensive. The thermal insulation materials in the domestic market have their own disadvantages, you'd better take the building demands into consideration, and use the materials that are within the acceptable range. I hope my answers help you.
