Q:I want to consult the fire resistant level standards of external wall thermal insulation materials.
1, The thermal insulation material that has level A combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2, The thermal insulation material that has level B1 combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3, Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See article 4.3.6 in the 2009 edition construction technical measures. Level A insulation material is just for fire protection, so its thermal insulation performance is worse than the organic XPS or EPS materials. Hope this will help you.
Q:How many kinds of refractory materials are there in the EI?
I suggest that you contribute articles to foreign SCI journals for the odds are better, and generally the articles that fill the bill will not be rejected. The traditional refractory materials can contribute to EI journal. If being rejected by EI journal, you can also contribute to Russia's journal Industrial Ceramics and Refractories. I didn't contribute to the Journal of Wuhan University of Science and Technology, the receiving cycle is almost 3 to 4 months. Though the impact factor is low, domestic EI journal is not so good, it is still SCI journal. This is my own experience, please take my advice. The best journals are the Journal of the American Ceramic Society and the Journal of the European Ceramic Society, I heard that they are not bad. But the best domestic EI refractory material journal is the Journal of The Chinese Ceramic Society. It is very long, but if it belongs to your university, it is another pair of shoes. Journals now all want to have materials about functional ceramics, and they don't want Chinese articles, if your English is not well enough, you can choose Ceramics International and Japan Ceramics but they have strict manuscripts reviewing standards.
Q:How is the division of the fire resistant level of the rock wool board?
The fire rating of European style rock wool board is level A , which uses Da Guang Beijing Jinyu rock wool board, with the main advantages are: 1, High acidity coefficient: The high coefficient of acidity greatly improves the life resistance and weather resistance of the rock wool board. 2, Hydrophobic air permeability: According to the picture, Jinyu Star rock wool is water-repellent, at the same time it also has breathability, so the liquid water is not easy to dip into the rock wool, and the water vapor and other gas molecules could pass through the rock wool. In particular, the insulation materials have this feature which enables the building to have "respiratory function" thus making the room more comfortable and preventing anti-mildew phenomenon happening indoor. 3, Environmental protection: The goldfish can survive freely, which just shows it is environmental; 4, High strength: The advanced pleating and curing technology make the rock wool board tensile and high compressive strength. It not only can be applied on the external wall thermal insulation and sandwich board core material, but also can be used to make structural cotton in the flexible waterproof roofing. Its quality is so stable that it is convenient in construction and durable in use. 5, Fireproofing: Not just talking about the fire rating, but the fireproofing time, which is generally up to two hours, and can be used for lining thermal insulation fire-resistant part of the glass curtain wall, through-wall pipe seal, pier between two windows, window sill wall and other parts; 6, Derived advantages: Agriculture applies the soilless cultivation cotton;
Q:what's the detailed address of fireproof and thermal inuslation matertial market?
following are the detailed address of fireproof and thermal inuslation matertial market: Central China Building decoration materials market,Hanxi 1 road No 95, Xinyongan Tangcai decoration material makert, Jianghan district Tangcai road No 53, Baoye decoration material wholesale market, Wuhan Wuchang district Minzhu road No 620.
Q:What are the characteristics of clay refractory materials?
Clay refractory has excellent performance in anti fatigue. The fatigue strength of the general metal is 50% ~ 40 of the tensile strength, and some composite materials can be as high as 70 ~ 80%. The fatigue fracture of the composite is from the matrix, which is gradually extended to the interface between the fiber and the matrix. Therefore, the composite material has omen before destruction, and it can be checked and remedied. Fiber composite material also has good performance in anti vibration fatigue. The fatigue life of The helicopter rotor made of composite material is longer that made of metal. I hope my answer will help you!
Q:What materials is silicious thermal insulation board made of?
Refractories that contain more than 93% of the monox are acidic refractory materials which include ordinary silica brick, high-density and high-purity silica brick, silica brick that contains chromium, fused quartz products, unburned brick and siliceous ramming materials. It has good softening temperature under a fixed load and can resist corrosion of acid slag, but will have chemical reaction with alkaline slag. Silicious refractory of industrial value mainly is crystalline quartz, such as α and β quartz, tridymite and cristobalite.
Q:Who knows the new fireproof and thermal inuslation matertial?
New fireproof and thermal inuslation matertial: foam concrete building blocks brick. The foam concrete building blocks brick is a new fireproof and thermal insulation material, with distinct advantages compared with the organic insulation material . Foam concrete can be used as wall materials, and it has a good self-insulation properties, so there is no problem of dropping off the outer insulating layer. A small part takes external wall exterior insulation, with mostly anchoring or dry hanging, which are not easy to fall off. Very few uses paste. Since the foam concrete and wall materials are of the same nature and strong adhesive, so it is also not easy to fall off.
Q:How long usually will the A-level fireproof materials prevent the flame?
The classification of A-level materials is based on GB8624 - 2006 building materials and products combustion performance of grading method. Specific technical requirements are: 1, temperature ≤30 degrees; mass loss rate ≤50%; continuous burning time is 0; 2, the gross calorific value of main components, overall products, external non-substantial components ≤2.0MJ / kg; any internal non-substantial component ≤1.4MJ / kg;
Q:What are the characteristics of the carbon composite refractories?
The features of carbon composite refractories: 1. It is with an aggressive high thermal shock resistance 2. Good resistance to molten steel and slag
Q:What is the fire endurance of ceramsite concrete blocks?
The heat conductivity coefficient of grade 800 hollow building blocks in ceramsite concrete is 0.23 and fire endurance is 4h. Ceramsite concrete has strong construction adaptability. It can not only compound concrete material with different unit weight and strength(It changes with the structure of thermal insulation or bearing structure) according to the different purposes and functions of buildings, but also is easy to construct. It is suitable for industrial production of a variety of construction methods. It can not only make all types of components(board, block, girder, column, etc) by using production process, but also can use mechanization construction of cast-in-place. The strong adaptability of construction of ceramsite concrete is not comparable to any other lightweight building materials(such as air-entrapping, etc.).
