Insulation Ceramic Fiber Yarn Reinforced With Fiberglass

Q: Do you know what the main indicators are for the inspection of refractory materials? Thank you very much for your requests and reports: Porosity, volume density, water absorption, true density, thermal expansion, thermal conductivity and heat capacity.

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: What is the classification standard of fireproofing material levels?: the following are the criteria: Currently fire materials levels mainly include:class A : incombustible building material,which almost doesn't burn. class A1: non-combustible, without open fire, class A2, non-combustible, it needs to measure the smoke and be qualified. class B1: nonflammable building material: nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion?source. class B1: combustible?building?materials: combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. class B3: inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster. In addition, according to different standards, fire-proofing materials' grade partition is different: DIN4102: A1, A2, B1, B2, B3: EN13501-1 A1, A2, B, C, D, E, F

Q: Is there anyone who can explain how to grade the level of fire insulation board?: The classification of fire proof level for thermal insulating material 1, Burning performance of building material can be classified into the following several grade according to national standard GB8624-97: Non combustible building materials: Non-conbustible material. Class B1: Refractory building materials: Flame retardant materials have good flame retardant effect.

Q: What is refractory cement?: Refractory cement is also known as aluminate cement, whose major mineral are monocalcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminate as well as a small amount of dicalcium silicate (2CaO · SiO2), etc. The advantage is that it is easy to use, able to harden if mixed with added water without other binding agent usually. Refractory aggregate and powder can be added into it. If you use refractory cement purely, it will produce a lot of cracks after high temperature.

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 differences of ceramics and refractories? Is the ceramics belonging to refractories?: The ceramics and refractories are different with the porcelain ceramic with high temperature of 1300℃ as household porcelain refractory. The porcelain refractory material of 1450℃ as the same as the aluminum oxide, kaolin, refractory clay and other raw materials demand the deployment ratio of the raw material the same as the temperature.

Q: What is the limit of fireproof rolling shutter?: Fire proof door can be divided into Serie A, B and C in terms of fire endurance limit, fire resisting limit are not should be less than 1.20h, 0.90h and 0.60h. Set firewall has difficult sites can use fire shutter fire partition separating, when the back fire surface temperature rise refractory limit determination conditions of fire shutter, the fire resistant limit not less than 3H; when employed does not include back fire surface temperature rise do fireproof limit determination conditions of fireproof rolling curtain, on both sides of the shutter should be set up a separate closed type automatic water spraying system protection, sprinkler system continuation of time should not be less than three hours.

Q: What's the A grade fireproofing material?: Main materials are steel, wood, steel and wood. Fire door is one of the measures for buildings fire separation, and it is generally installed at the firewalls, entrances and exits of stairwells or tube well openings, which is required to play the role of fire protection and smoke control. Fire door plays an important role in preventing the spread of smoke and fire and reducing damages, so it must be strictly required. Fire dooor is classified into three classes of A, B, C, and their fire insulation and fire integrity is greater than or equal to the following values: A class fire door: 1.5h; B class fire door: 1.0h; C class fire door: 0.5h. It is in accordance with the provisions of 4.5.1.2 Article in GB12955-2008 "New Standard of Fire Doors".

Q: Refractory inquiries: Special refractories are new inorganic non-metallic materials developed on the basis of traditional ceramics and refractory materials.
