Q:How long is the fire endurance of the rock wool board?
In the fire safety rules, of the building materials are classified as non-burning combustion body, difficult to burn the body and burning body categories depending on its difficulty level of burning. Rock wool board is the fiber processed by the coated steel sheet and basalt minerals and other inorganic minerals,and the building panels through artificial composition. Because that the dominant sectors, like, steel plate and rock wool are non-combustible materials, so it should be considered as non-combustible component. The fire resistance of rock wool board has its judging criteria. Loss of support capacity, loss of integrity and loss fire insulation function. Its fire resistance is within 2 hours.
Q:How long is the fire-resistant time of fireproof wooden door?
fire endurance class A (1.5 hours), class B (1.0 hours), class C (0.5 hours).
Q:How to classify the grade of wall fireproof and thermal inuslation matertial?
The level classification of wall fireproof and thermal inuslation matertial: Grade A: incombustible building material: Material almost with no combustion. Grade B1: nonflammable building material: Nonflammable material has good flame resistance. It is difficult to fire in case of fire in the air or at high temperature. It is not easy to quickly spread. After the fire source is removed, combustion stops immediately. Grade B2: combustible building material: Combustible materials have a certain flame resistance. It will immediately burst into flames in case of fire in the air or at high temperature and is easy to lead to the spread of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. Grade B3: Flammable building material: It has no flame-retardant effect and is highly flammable. Fire hazard is very large.
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:What's the refractory material?
Main components of basic refractory are magnesium oxide and calcium oxide, and magnesia brick is commonly used. For the magnesia brick with magnesium oxide content of more than 80%-85%, it has good resistance to basic slag and scum, and it has higher refractoriness than that of the clay brick and silica brick. It is mainly applied to the open hearth furnace, oxygen-blown converter, electric furnace, non-ferrous metal smelting equipment and some high-temperature devices.
Q:What is refractory aggregate?
Refractory aggregate is fire-resistant product improved with low temperature binder, chemical compound and normal temperature strength.
Q:I wanna ask about the thermal insulation material fire resistant level?
The inorganic have glass wool \ foam glass Bian \ the best of organic is phenolic foam \ phenolic foam composite cement layer is level A.
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 are the construction measures of refractory material in winter? Please descriptive briefly.
Binding agent should be attaced great importance to when construction is conducted in winter. Generally if the bingding agent is water or cement, antifreezing measures should be taken.
Q:What is the main constituent of refractory brick?
There are several refractory bricks, including clay brick, carborundum brick and chromium-carbon. The type you said may be refractory bricks made from bauxite.
