Q:Is it normal for caable fire resistant material to catch on fire?
Abnormal; aging is certainly one of the cause of the fire. That is caused only because of poor insulation and aging caused by short circuit, but a more important reason is configuration of air switch does not meet the requirements. If the capacity of air switch equals that of the cable, trip will happen at the moment when current is overloaded, not causing a short circuit or over current fire.
Q:What is the material composition of the new fire-resistant coating?
The basic composition of thick coating steel structure fire is: Binder (Portland cement, magnesium oxychloride or inorganic high-temperature bonding agent), aggregate (expanded vermiculite, perlite, aluminum silicate fiber, mineral wool, rock wool, etc.), chemical additives (modifiers , hardening agent, waterproofing agent) and water. Fireproof coating binders Portland cement, magnesium oxychloride cement and an inorganic binder of the fire-resistant coating for steel structure base material. The conventional inorganic binder include alkali metal silicates and phosphates substances.
Q:How to divide the materials according to the National Fireproofing Material Standard?
Each country has its own fire safety standards, I do not know which country's standard do you want to know, and each country of fireproof material to the division level is not the same. GB GB 8624, the German standard DIN 4102-1, the British standard BS 476, French standard NF P92 -501 and so on. GB 8624 is Chinese building materials and grade of combustion performance. The information coming form fire resources network (FireTC.
Q:The fire prevention board line is made of what material?
(1) if it's real wood floor, the line should be made of wood. The ready-made wooden line, walnuts, price range depends on the texture width. The common width is 100 mm. One linear meter is around $17 - $30. Paulownia is cheaper with one linear meter more than 10 yuan. When it is composite wood floor, high-density plate modelling line can be used. The price is commonly between 40 to 80 yuan (2400 x 1200 mm), which depends on the thickness and density and also the factory. There are also imitated wooden aluminium line. (3) if it's the marble ground, you would better use marble line, which is 200 yuan one square meter. It's price is also unequal. The imitated stone is also available. There are a lot of kicking decoration materials and it depends on how you use it. That is to say crural line should be coordinate with the ground. It means that it sjould not only to be beautiful but also to be practical. It would be better if it is relatively cheap as well.
Q:Why can aluminium hydroxide not be used to make refractory material?
Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.
Q:What types does soft fire prevention materials have?
1. In new fire retardant coatings, expanded vermiculite, expanded perlite heat insulation material and cenosphere adiabatic powder are an integral part of thick film type fire-retardant coating. They are also the main factors influencing the fire fire retardant coating performance level. And fireproof heat insulation performance of fire retardant coating is based largely on the back fire coating surface temperature factors, and also related to the fire resistance. If the time of reaching the same temperature is longer, it means its insulating fire stays is better, so the fire resistance is higher. 2. The new type of fire prevention board. Now new type of fire prevention board are welcomed by the people is mostly due to its environmentally friendly. And with an increasing number of high-rise building, the fire and strength requirements are constantly improved. It is a big test for plate performance and the standard. Now fire prevention board mainly adopts siliceous materials or calcareous materials, and then stick with the fiber material, light aggregate, binder and the mixture of chemical additives. In this way, it can not only act as fire prevention, but also can improve the thermal insulation performance, and with light quality, good bearing capacity, good durability, no aging problem. More importantly, it is environmental protection. 3. The new flame retardant materials. New flame retardant material currently focus on in polymer composite material, which performance is good with very good high temperature resistance and heat resistance, therefore it's not easy to deform after the fire. At high temperature, it also can use for a long time, so as to ensure the safety.
Q:what is the specs of thermal insulation refractory slab ?
fireproof panel is also called refractory slab, which refers to a layer of veneer. Its thickness is generally about 0.8 mm and there is a veneer made after compression of surface layer of paper, colored paper and multilayer kraft paper. Wear-resistant, heat-resistant and fire-resistant properties, scratch resistant and easy to clean, rich colors and good stability.
Q:What are the filling refractories in door leaf of class A fire resistant door?
That depends. Most are perlite fireproof panel, MC composite material and other fireproofing materials, vermiculite fireproof board, while some are foam door filling board.
Q:which kind of refractory is used in golden smelting furnace? How about his using temperature
generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.
Q:who knows how to classify the fire resistant levels of fireproofing material?
Grade of fireproofing material: Class A: Incombustible building material, almost without burning. class A1: Non-combustible, no open flame,class A2: Non-combustible,it needs to measure 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 B2: 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.
