Q:Can anyone tell me which materials are fire-proof high temperature resistant material?
Fireproof high temperature resistant materials such as: Quartz, tridymite, cristobalite, chalcedony, flint, opal, quartzite, White silica sand, diatomaceous earth, the silicon oxide (SiO2) contained in these siliceous materials is at least 90% . The silicon oxide in some pure raw material can be above 99 %. Siliceous materials are acidic in high-temperature chemokinesis. when existing metallic oxide or contact with metallic oxide, they will conduct chemical actions and conbine into fusible silicates. Therefore, if the siliceous raw material contains a small amount of metal oxide, its heat resistance will be seriously affected..
Q:Who knows how to divide the building fire grade and fire resistance grade?
I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on.
Q:What is the function of red stone refractory materials
Q:Who knows how many fire heat preservation material are there?
There are many kinds of fire proof materials. The major material used in construction industry is fire proof and thermal insulation material, mainly include vitrified micro bead insulation board, class A expanded bead fiber board, rock wool board, plastic extruded sheet, polyurethane insulation board
Q:Which fire-resistant materials have good viscidity?
The viscidity of fire-resistant materials is also known as the binding performance of fire-resistant materials. It can be divided into chamotte and chemical binder. Both can work at normal or high temperature. The most commonly used chamotte are soft clay and aluminate cement. The commonly used chemical binders include sodium silicate, phosphoric acid, aluminum sulphate, aluminium phosphate, phenolic resin, etc. Fire resistant material is a complicated and overloaded system and we cannot know its materials and chemical components from the name alone. Both gunning mix and repair mix contain binder components. If they can used after adding water, then they may contain clay or fire resistan aluminum silicate cement.
Q:What problems should be paid attention to while using refractory materials under a controlled atmosphere?
Pay attention to the performance of the materials, and the use of non oxide materials!
Q:What is neutral refractory? Can refractory suppliers tell the main components of it?
The material using Al2O3, clay, bauxite and corundum as the main components is neutral material; the material using MgO and CaO as the main components is basic material; the material using SiO2 as th emain component is acidic material.
Q:What are first rate fire resistant window materials?
class A window not less than 1.2 hours, class B window not less than 0.9 hours, Class C window not less than 0.6 hours. technical requirments: 1, materials and accessories (1) the window frame is made with a certain strength sufficient to safeguard the integrity and stability of the steel frame or wooden frame. (2) steel frame and mound layer can choose the galvanized steel plate or stainless steel plate. Its selection standards is in line with GB12955 "Steel Fireproof Door General Technical Condition" provisions of Article 5.1. (3) wood frame and mound layer material selected from the standard should be consistent with GB14101 "General Technical Conditions of Wooden Fireproof Door" in the provisions of Article 5.1.1. (4 ) steel, wood frame the inside filler material should be incombustible material. (5) fireproofing glass can be used without affecting the fire windows fire resistance test approved product. light transmittance of glass should not less than 75% of commom sheet glass which is the same number of layers. ( 6) a sealing material between the frame and the fire-resistant glass flame retardant materials should be used, which can play the role of fireproofing and smoke insulation in case of fire (7) hardware fitting should be tested as approved supporting product
Q:It the Special Fire-Proof Material belonged to ceramics? Is there a national standard of the Special Fire-Proof Material?
The fiber and reinforcing material of the metal ceramic is also belonged to the Special Fire-Proof Material. ~~~~GB is too much trouble, GB online should ~~~ Lei Bao Refractories for you. The high temperature inorganic coating. 5. The refractory compound. 3. The high melting point oxide. You can search it on the internet according to the classification~~~~ The special refractories can be divided into five categories: 1. metal ceramic
Q:What are the specifications of fire resistant bag?
Fire resistant bag is featured by wear resistance, resistance to heat, shock, acid and alkali, somke, fire, bacteria, mould and static electricity. Fire resistant bag is generally used for table top, desktop, wall face, cabinet, office furniture, wall-hung cupboard, etc. The common specifications include: 2135mm×915mm, 2440mm×915mm, 2440mm×1220mm, thickness 0.6-1.2mm. I hope it can help you.
