Bauxite is a natural, very hard mineral used predominantly in road systems for its high-friction and anti-skid properties. The majority of public sector systems will specify that Calcined Bauxite be used in their road and pedestrian crossing installations.

Its hardness is also beneficial in internal and external industrial flooring applications where a very hard and long lasting mineral is required to give high-friction, anti-slip performance.

Pigmented Bauxite, which is produced in-house and is available in the main safety colours, is used to give an element of high visibility to anti-slip and anti-skid decorative surfaces.

1.0 - 3.0mm particle size is shown for pigmented bauxite.

It is used extensively in warehouses, loading areas, high visibility pedestrian and vehicular safety areas.

 

What can bauxite do? 

1. Aluminum industry.

2.  Precision casting.

3.  Refractory industry.

4. Silica acid aluminum firefibre

5. Mixed with magnesium oxide,it can be an nice bonding agent,especially for pouring entire steel teeming ladle lining

6.  Manufacture bauxite cement,grinding abrasives.

7. Ceramic industry,and chemical industry for making aluminium compounds

Q:What is the interior fireproof thermal insulation material?
polystyrene foam board, glass fiber spraying, polyurethane foam, thermal insulation system of inorganic wall. Use "DY" inorganic active thermal insulation material, have small thermal conductivity, large heat storage coefficient, better strength and achieve better thermal insulation and energy-saving effect when used in wall . Wall should definitely not crack and hollow because of high temperature in summer. It doesn't crack and shed because it is influenced by stress during heat expansion and cold contraction in cold winter.
Q:What are the new refractories? What are the features? How about their application and development?
In metallurgy, in what position should it be used, in order to make the best. Answers are as following. In iron, steelmaking or converter. When questioning, pay attention to the ways. Answers: Try to use synthetic refractory materials.
Q:Refractories for iron-making blast furnace?
Cement kilns?
Q:what grades are fire resistance of fireproofing glass divided into?
Fire resistance of fireproofing glass is generally divided into three levels, class A glass can satisfy the requirements of fire resistance and thermal insulation at the same time. Class B, it's a kind of fireproofing glass that can satisfy the requirements of fire resistance and heat radiation strength at the same time. Class C can satisfy the requirements of refractory integrity, if you want to know more specific requirements, you can also surf the internet for a more detailed description.
Q:How to distinguish the fire resistant level of construction materials?
There are 3 conditions for building components to reach fire endurance, namely: Loss of ability to support; loss of integrity; loss of fire insulation function. As long as one condition occurs, fire endurance is reached and the time before it is called fire endurance. 1), loss of ability to support: If the specimen bearing capacity and rigidity reduce, section area shrink, collapses or deformation exceeds specified numerical value because it cannot bear the load of original design under flame or high temperature, it loses the ability to support. 2), loss of integrity: It mainly refers to the thin wall separating component(such as stairs, windows,partitions, ceiling, etc.) burst or partially collapse under flame or high temperature, and penetrating fracture or opening appears, and the reverse side even burn. For example, when the floor is under flame or at high temperature, the flame spread to the upper room, which indicates that the integrity has been damaged. 3), loss of fire insulation function: It mainly refers to that seperating components loses thermal insulation and excessive heat conduction. In experiment, if the average temperature of component unexposed surface exceeds 140 ℃, or if any spot at the unexposed surface exceed the initial temperature of 180 ℃, the component loses fire insulation function.
Q:Who knows the setting requirements of roofing fire barrier zone?
curtain wall style architecture should meet the following requirements: The space between the inner cavity of the base wall and curtain wall and base wall, pier between two windows, window sill wall and skirt wall should be sealed by the fire-proof sealing material at each floor. I hope I can help you!
Q:How is the fire endurance of the fireproof paint?
Fireproof endurance. fire resistance test of certain building components showed by standard time temperature curve from starting of fire to lose the supporting capabilities or its integrity or fireproof property. The fire proof endurance is 5hours.
Q:What does the function of SiC for refractories?
Anti-wear! High intensity!
Q:I wanna ask about the thermal insulation material fire resistant level?
1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials.
