Ceramic Fiber Mat Thermal Resistance

Q: A chemical problem with refractory materials: In chemistry, there is never absolute

Q: What brands are the best in the A-level refractory materials?: A-level refractory materials: Dulux, Nippon, Carpoly, Skshu and Smoz. Fireproof boards are the most common materials in the market. There are two are commonly used: one is HPL decorative plastic laminates with advantages of fire- ,moisture-, wearproof and oil resistance as well as easy to wash, besides it has a great variety of colors and types. Another one is glass fiber magnesite fireproof board, the out layer of which is decorative materials while the inner layer is mineral magnesium fireproof materials which can resist a high temperature of 1,500 Celsius degree but it is not a good ornament.

Q: The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?: gas permeable brick have two types:built-in type and external mounted type. the built-in gas permeable brick and the external mounted gas permeable brick are usually made by fire burning, and small part of bricks are made by the low temperature heat.

Q: Why does refractory need to add coarse firstly and then add fine aggregate?: Binding agent can wrap particles and improve binding effect.

Q: What refractories are resistant to fluorine gas?: It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica?brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.

Q: Which refractory material is better in China? Industrial furnace, mainly in non-ferrous industries, glass kiln, cement kiln business.: Such solid nano microporous insulation material with nano inorganic refractory powder special, with a huge surface area, nano particles contact between the minimum point contact point contact thermal resistance is very large, the heat conduction effect of the material becomes very small, resulting in heat conduction coefficient of solid such nano porous insulation materials very small; nano pores formed of nanoparticles, the average size of 20 nm, and the average free path of molecular thermal motion at room temperature under static air is 60 nm, thus locking the air molecules in powder within nano pores, making the micro convection heat transfer effect between the stationary air molecules disappeared. The room temperature thermal conductivity of solid such nano microporous insulation material is lower than the static air; at high temperature, the main effect of heat transfer heat radiation, Good energy-saving insulation materials with nano microporous infrared additive special, stop at a high temperature and reflected infrared radiation, reduce the heat radiation effect to the lowest point, the radiation heat transfer coefficient of materials under high temperature is reduced to the lowest value.

Q: Who knows what kind of fire prevention materials are there?: 1, Fire-proof board Fire-proof board is the most frequently used materials in the market. There are two kinds of fireproof boards which are commonly used; one is the high pressure decorative board, which has the advantages of fire prevention, damp proof, abrasion resistance, oil resistance, easy cleaning, and more variety of colors and designs. The other one is a glass magnesium fire board, the outer layer of which is a decorative material, the inner layer of which is a mineral glass magnesium fire material. It can resist 1500-degrees high temperature, but not suit for decoration. The installation of fireproof ceiling in the exit passageway, stair well and corridor can ensure safety evacuation, and protect people from the spread of the fire. 2 Fire-proof door Fireproof door is divided into wooden fire proof door, steel fire proof door and stainless steel fire proof door. Usually the fire proof door is used for the opening of the firewall, the entrance to the staircase, the evacuation of the aisle, the openings of the pipeline and other parts of the building, and it has an important role in fire separation and reducing the loss from fire. 2 Fire resisting shutter I hope it may be helpful to you.

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: What are the specifications of fireclay bricks?: Specifications of fireclay bricks are shown in the figure;

Q: Who knows what material is in the center of fireproof rolling curtain?: made of inorganic super fireproof rolling curtain: Glass fiber cloth ceramic fiber cloth (reinforced stainless steel wire) ceramic fiber blanket aluminum foil cloth. Hope my answer will help you.
