Q:Who knows how many fire heat preservation material are there?
There are many kinds of fire proof materials. The major material used in construction industry is fire proof and thermal insulation material, mainly include vitrified micro bead insulation board, class A expanded bead fiber board, rock wool board, plastic extruded sheet, polyurethane insulation board
Q:what's the varieties of thermal insulation material with A level fire rating?
the main A level fireproof material is rock wool now (note:it is rock wool not mineral wool). A1 level fireproofing, now the largest producer is Taishi rock wool Co., Ltd.; hope my answer can help you, thank you.
Q:How is the fire endurance of the fireproof paint?
fire endurance of fireproof paint is from 1 to 4 hours. Mechanism: Fireproof paint itself is flame-retardant or non-combustible, protecting the substrate from direct contact with the air,delaying the time for catching fire and reducing the burning speed. fireproof paint decomposes with heat and releases non-combustible inert gas, thining out the flammable gas produced by the protected object, making it difficult to burn or slow down the burning. expansive fireproof paint expands under heat and forms a layer of carbon foam insulation to cover the protected object, delay the heat transfer in the substrate , prevent burning and possible losing of fireproof abilitiy because rising temperature.
Q:What is the the best matching ratio of refractory cement?
Refractory cement is very easy to use. Add some water and mix, and it will harden. Generally there is no need to add other binding agents, but you can add some refractory aggregate and powder. If you use only refractory cement, it will produce a lot of cracks after high temperature. Generally refractory cement can withstand temperature of about 1300 degrees. Refractory cement can be used together with ordinary sand, and the ratio of cement and the sand is about 30 percent.
Q:How is refractory material made?
It is made from polyester.
Q:How should refractory cement be used?
Refractory cement is very easy to use. Add some water and mix, and it will harden. Generally there is no need to add other binding agents, but you can add some refractory aggregate and powder. If you use only refractory cement, it will generate a lot of cracks after high temperature. Generally refractory cement can withstand temperature of about 1300 degrees.
Q:What are the filling refractories in door leaf of class A fire resistant door?
Perlite!
Q:Who knows that among refractory materials, insulation boards from which refractory material industry is superior in quality?
When casting ingot, after high temperature molten steel is poured into ingot mold, molten steel keeps shrinking during cooling, for example, killed steel is shrinking 3% --5%. because of fast heat dissipation of ingot head , some shrinkage holes appear at the head of ingot. Therefore, you should cut shrinkage holes which account for more than 15% of the ingot quality in the head while cutting steel ingot cogging. If effective measures were taken to insulate the head of ingot from heat, then the coagulation time of ingot head would lag behind in the body of the ingot solidification, which will greatly shrinkage holes, improve ingot yield so as to reduce energy consumption of steelmaking. Adiabatic plate can achieve this purpose. China Heng insulation board has the advantages of uplifting adiabaticity and small heat capacity, so that it greatly reduced heat loss of molten steel, And the tundish can be directly put into use without preheating, thereby saving a large amount of preheating fuel. So in the current process of continuous casting, the heat insulation board is the main material of tundish lining.
Q:How to distinguish the fire resistant level of construction materials?
Building materials fire resistant level is divided into four levels, among which the first level is the highest, with strongest fire resistance; fourth level is the lowest with weakest fire resistance. Fire resistance level of buildings depends on combustion performance and fire endurance of the building components. The building components refer to a series of basic components such as the building walls, foundations, beams, columns, floors, stairs, ceiling, etc.
Q:What's the requirements of fire-fighting criteria of heat insulating material?
Specific provisions go as the following article 8: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. Article 9: The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm. Article 10: the roof waterproof membrane or flammable insulation layer should adopt incombustible material to cover.
