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.

Q:Is there vermiculite in refractory?
In refractory field, vermiculite is usually used as fireproof thermal insulation material.
Q:What 's the highest temperature can magnesium plate glass resist ?
Glass magnesium plate (commonly known as magnesium oxide or glass magnesium plate) is a magnesium jointing material with stable performance made by adding modifier and processing ternary system composed of magnesium oxide, magnesium chloride. It is a new non-combustible decorative materials comprounded by moderately alkaline fiberglass net as enhanced material and lightweight material as filler. 1, Applications Wall panels, ceiling panels, fire-resistance boards, water-proof boards, boxes, etc.. It can replace wooden plywood panel and be made into dado, door panels, furniture, etc., or into distemper paint water paint to one's need, and can akso be processed into various types of plate surface. It is also applicable to projects undertaken in damp environment such as basement, civil air defense, mines. It can be comprounded with a variety of thermal insulation materials into compround thermal insulation materials 2, Product features: Magnesium plate glass is high temperature resistant, sound absorbing, and capable of preventing water, pests, dampness, corrosion, poison, pollution. Paint can directly be applied to the surface of the plate. Air nails are usable for the plate, to which ceramic tile can also be applied with good pigmentation High strength, flexibility when bending, convenient for decoration. It can be sawed, nailed, and glued. 3, the use of glass magnesium plate: Glass magnesium board is a basic intermediate materials Main occasions for applications: HPL Series: Top of the tunnel ceiling. Decorative plate series: Decoration in hotels, office buildings, residential buildings Board series: Ceiling, partitions, fire proof doors and other products. Sound-absorbing panels: Subway, railway stations, theaters, factories and other public buildings.
Q:Can anyone tell me what is the material of which the mould for refractory is made?
I can make the mould and give you a discount. If necessary, you can contact me at 261240643 (qq).
Q:What kind of refractory decorative board has good quality?
The unique design and personalized style of well-known brand "transit" rank highest in the field of domestic refractory slab. It is one of the largest manufacturers of high pressure decorating refractory slab in China. The production base covers an area of 40,000 square meters and the annual output is 4 million. It passes the test of Quality Supervision and Inspection Center of National Fire Protection Building Material and ISO9002 certification. The products pass international standards such as 4586, the United States NEMA and so on.
Q:The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.
With the advantages of carbon refractories especially excellent slag resistance and high heat stability, but graphite under high temperature oxidation, in order to improve the oxidation resistance of carbon composite refractory materials, often adding a small amount of antioxidants, to improve the oxidation resistance of carbon composite refractories. Antioxidant additives commonly used in metal powder, silicon powder, magnesium powder, silicon carbide powder and so on.
Q:what's the requirements of refractory for forge furnace?
operating temperature of forge furnace is 1000 ° C, reasonably choosing refractory for build furnace has an important meaning for guaranteeing the normal operation of the heating furnace, improving the service life of furnace and energy saving. general requirements for the properities of refractory: 1, it should be equipped with the properity of no deformation and melting under certain temperature. 2, it should be equipped with the neccessary structural strength without softening deformation in high temperature. 3, volume stability at high temperature, brick body won't be deformation or cracked due to expansion and contraction; 4, not broken and peel off under rapid changes of temperature or uneven heating; 5, resistant to chemical erosion of molten metal, slag and furnace gas,etc.
Q:Who knows what is the external wall thermal insulation materials for level A fireproofing?
In general, external wall thermal insulation materials can be divided into level A and level B by combustion grading. Level A is non-combustible material, and level B is combustible materials. A few years ago, the fire of the CCTV Building and Shenyang Hotel put the blame on the level B material. At present, the level A material is widely used, and the prices of same level A materials may be even cheaper than the level B material. Level A material is generally divided into thermal mortar, phenolic foam board, rock wool board and foam cement board. I hope this information can be helpful to you. Hope you adopt.
Q:What's the type of fire proofing thermal insulation materials?
Hello! Fire proofing thermal insulation material can be classified as inorganic thermal insulation material and composite thermal insulation material. According to the form, it can be divided into fibrous veneer, mineral wool, rock wool, glass wool, aluminum silicate cotton, ceramic fiber, microporous diatomite, calcium silicate, expanded perlite, expanded vermiculite, aerated concrete, bubble foam glass, ash, glass, clay, foam concrete, and pasted paste powder polystyrene particles insulation pulp, etc. They are characterized by flame retardancy and fire proofing and thus can be used in buildings with high fire proofing class. Among them, calcium silicate, aluminum silicate and asbestos can also be used for the thermal insulation for heat supply pipelines.
Q:What is shapeless refractory with high performance?
The popular ones are: Non-cement fine powder bonded castable is a functional refractory castable with nano material introduced.
Q:Graphite and other carbon materials may be oxidized to CO or CO2 at high temperatures. But why can they be refractories?
There is no contradiction for this. Any substance can be combustible, but different materials have different ignition points.There are many types of graphite. Pyrolytic graphite has a much lower ignition point. Therefore, as long as it reaches at a certain temperature, it can convert into graphite. Mostly, in practical applications (such as brake pads will add a certain amount of graphite), graphite is required to have refractoriness of below 1000 ℃. Graphite can serves as both the combustible and refractory material. So, it can be used as a fire-resistant and high-temperature-resisrant material because graphite (lamellar graphite) has a ignition point of at least 3000 degrees in an oxygen free condition. The above information is for reference only and is offered by Xin Ruida Graphite Company.
