Black SIC ball

Q: How to divide the fire resistant level of EVB?: Inorganic materials: Level A incombustible material is mainly divided into three levels, which attributed to two types of materials! Inorganic materials: Rock wool, foam cement, vitrified micro bead, foam glass organic: Eps xps polyurethane phenolic aldehyde, polystyrene particles are divided into two manufacturing techniques including field fabrication and pre-production polyurethane - now sprayed, precast slab eps, xps, phenol - now posted, precast slab (composite board)

Q: The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.: 3, the selection principle of antioxidant and its thermodynamic and kinetic mechanism31 selection principles of antioxidants:(1) according to the thermodynamic data and the conditions of use, the possible condensed phase and the vapor pressure of each gas phase are determined;(2) compare the size of each coacervation and oxygen affinity, and the possibility of reaction with CO.(3) the influence of various reactions on the microstructure of brick was analyzed.The thermodynamic and kinetic mechanism of 3.2 antioxidantsFrom a thermodynamic point of view, at the operating temperature, the additives or additives that react with carbon react with oxygen more closely than carbon and oxygen, giving priority to carbon oxidation, thus protecting carbon;From the analysis of dynamics point of view: the compound additive with oxygen and carbon monoxide reaction changed the microstructure of carbon composite refractory materials, such as increasing the density, blocked pores, hinder the diffusion of oxygen and reaction products.

Q: Physical and chemical indicators of various refractory.: it depends on what it is for. There are thousands of kinds of refracroties. You should just ask what you need.

Q: The classification of fire-resistant material: There are various refractory materials classified according to the chemical properties of material: Min< manufacturing technique: neutral refractory materials, pipes, etc. Standard model: baidu.hiphotos;8 simatic carbon composite refractory material zirconia based refractory material special fire-proof material 6; or a acute angle of 50～70° and material forms. 3.

Q: Refractory factory grinding brick dust harmful to the body?: Therefore, in the workshop work must pay attention to do their own protection.

Q: what's the fire endurance of fireproof?panel?: fire endurance of fireproof?panel generally is 3 hours. For example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof?panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. fireproof?panel, also called fire resistance board, scientific name is thermosetting resin impregnated paper laminated wood,english abbreviation HPL(Decorative High - pressure Laminate) is fire resistant building material for surface decoration and has rich surface colors,lines and special logistics performance, it's widely used in interior decoration, furniture, cabinets, laboratory table, external wall, etc.

Q: Who can introduce the external wall thermal insulation materials fire rating regulations?: According to public fire-fighting [2007] No. 182, the contents of the notification on the implementation of a number of issues of national standards GB8624-2006 "building materials and products combustion performance classification", since there is large differences between the new version of the standard GB8624-2006 and the old version of GB8624-1997 in the principle, hierarchical structure and test methods. According to the cintent of notification, in order to ensure a smooth transition between the old and new standards, the current national standard "Fireproof? Specification of Building Interior Decoration?Design" GB50222, "fire?safety?rules of tall civil buildings design" GB50045, "Fireproof? Specification of Building Design" GB50016 have not completed the relevant amendments, the new classification method of GB8624-1997 and GB8624-2006 can be used for temporary reference in terms of combustion performance of materials . From GB8624-2006 standard implementation, the classification of combustion performance is too granular, which do not match to the actual construction of the current project in our country. Therefore, the relevant departments carry on the 3rd amendment for the GB8624-2006 standards, namely GB8624-2012, and it will be released on December 31, 2012 and implemented on October 1, 2013. The combustion grading requirements in the standard: Level A is non-combustible materials (products); level B1 is nonflammable material (products); level B2 is combustible materials (products); level B3 is flammable materials (products).

Q: Refractories for iron-making blast furnace?: This question is too professional - as far as I know, there are blast furnace noumenon bricklaying - trough slag runner fire-resistant model ~ main channel carbon rod ~ ramming mixes ~ ~ I do not know the specific details.

Q: How many refractories are there for boiler above 1200 ℃？: Ordinary clay brick is for burning layer, red brick for external wall, light clay brick for thermal insulation layer, built by clay refractory mortar. Sindeyuan Refractories.Hope you adopt. Thank you. In fact, there are many manufacturers producing furnace burden. We has been using products of Huaheng, which are anti-erosion, easy to construct and can improve production efficiency, reduce steelmaking cost.

Q: what's the materials of fireproof?housing?: there are mainly several fireproofing levels, it is divided into flame retardant and non-combustible! at present t the main fireproofing materials on the market are made from rock wool board! it is incombustible?material, of course, the price is relatively high. Other common materials are fire?retardant foam.
