Q:How long is the fire-resistant time of fireproof wooden door?
Wooden thermal insulation fireproof door using flame-retardant timber or flame-retardant timber products to make door frames, skeletons of door leaf, door panels. If the door leaf need to be filled with materials, the filling materials should be fireproof thermal insulation materials which is non-toxic and harmless to human body, and matched fireproof door composed of fireproof hardware. Use doors without age limits.
Q:Is there anyone who can explain how to grade the level of fire insulation board?
1, Combustion performance of building material is divided into the following several class according to China's national standard GB8624-97 Class a: Non combustible building materials: Non-conbustible material. Class B1: Refractory building materials: Flame retardant materials have good flame retardant effect. It hardly catch on fire in the case of open flame and high temperature, do not spread fire quickly, and when the fire source is removed, fire will be stopped immediately. Class B2: Combustible building materials: Combustible materials have certain flame retardant effect. In case of fire or under high temperature, it will immediately burst into flames, easily leading to spread of fire , such as poles, wooden frame, timber, and wood stairs. Class B3: Combustible building materials: Without any flame retardant effect, will be burnt easily, resulting in high risk of fire. I Hope my answer will help you.
Q:What is the role of adding chromium oxide green in unshaped refractory materials
Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.
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:how about the performance of aluminum silicate fire proof thermal insulation?
aluminum silicate fire proof thermal insulation board has a good performance. it is a artificial board that separates the wood and plant fiber by mechanical and chemical methods and mixed the adhesion agent and water-proofing agent, molding by high temperature and high press. the density of fiber. tha above information is coming from the Internet and it is just for reference.
Q:Using what kind of melting aluminium furnace refractories is more appropriate?
If it's the ordinary, you can use high aluminum refractory brick with general clay, GB/T 3994-2005 clay heat insulation refractory brick. If you need these with good material, there is high alumina thermal insulation refractory brick, GB/T 3995-2006 high aluminum heat insulation refractory brick, models have A13 and material is the alumina, A13 50 u, high insulating brick B5.Intermediate insulating brick B2, etc. Dolomite brick: good hang kiln performance, good erosion resistance, but brick is usually without f - CaO, hydration, and difficult to transport and storage, less used in the production. Magnesia-chrome bricks: good hang kiln, used in calcining zone. The disadvantage is that its thermal shock resistance is poor and plus hexavalent Cr is toxic, the production and use of magnesite chrome bricks in international countries gradually reduce. Now unit using the brick find replacements as soon as possible.
Q:Could you tell me how does fire protection standard of decorative material is divided?
Level of fire prevention materials: A grade: non-combustibility building material, almost without burning materials. A1 level: non-combustible, no flame A2, non-combustible, to measure smoke, to be qualified. B1 level: flame retardant building materials: flame retardant materials has good flame retardant effect. It is uneasy to burn when encountering open fire in the air or under high temperature and is not easy to quickly spread, and when the fire source move, it will stop burning immediately. B2 level: combustibility building materials: combustibility materials has good flame retardant effect. It will immediately burst into flames when encountering open fire in the air or under high temperature. It easily leads to the spread of fire, such as timber, wooden frame, wooden beams and wooden stairs. B3 level: flammable building materials, without any flame retardant effect, easy to burn, and with a very high fire risk.
Q:What kind of material is good for cabinet fireproof board
Natural stone marble: Advantage: Rich color, texture is more soft, easy for cutting or molding; shortcomings: Because it is a natural formation, micro cracks will get easily broken. If sewage infiltrates in during production and transportation, it is difficult to clean and it will get cracked. In the daily cleaning, residue will be filled into the cracks when using cloth to clean. then the material will become breed bacteria. In the long process of the formation, natural stone material may cause harm to human health due to the formation of heavy mental which is radioactive.
Q:Does anyone know fire-proof material of fireproof wooden door?
Fireproof wooden door goes through the flame treatment, so it can prevent fire. Its principle: Fire-retardant treated timber has become flame retardant material itself and its fire endurance has increased. The commonly used method of fire retardant treatment for timber including: Spraying method, soaking method, boiling method, vacuum method, vacuum-pressure method.
Q:What do refractory materials include?
It is so difficult.
