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:What defect does fused cast refractories have ?
The impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement.
Q:What kind of material is good for cabinet fireproof board
Cabinet fireproof plate can be classified into fiber cement fireproof board, metal fire proof board, mineral wool fireproof board, perlite fireproof board, all sorts of fire prevention board. Fiber cement fireproof board is a kind of ornament plate using siliceous or calcareous as main materials and combined with a certain proportion of fibre material; metal fireproof board is a kind of decorative plate made of aluminum plate, stainless steel plate, color steel plate and other metal materials as the main raw material and added by certain flame retardant materials. Mineral wool fireproof board is a decorative plate made of mineral wool and glass wool; perlite fireproof board is hollow fire proof plate made of low alkalinity cement as the main raw material, and supplemented by certain perlite with fireproof function as filling. Fiber cement fireproof board is a kind of new material increasingly gets popular with superior heat insulation, sound insulation performance, belonging to the A1 level fire materials 1, Suzhou total surplus purification A-grade fireproof rock wool colored steel rock wool board range of applications: Partition ceiling material: Rock wool reference price: On a square 58.00/2 meters, Huarui thermal insulation fireproof materials aluminum silicate refractory aluminium silicate A-grade fireproof heat insulation aluminium silicate plate temperature: 1000 core material: Reference price for aluminum silicate fiber cotton: $3500.00\ ton
Q:Which kind of refractory floor is easy to use? ?
Fireproof wood floor includes three types, and according to your requirement, I think that the third type is more suitable or is easier to use. Here are the three types, and you can choose form them. A. Wear-resistant composite solid wood floor It is also known as super durable multi-layer solid wood floor. Its surface is inorganic glass fiber material and special paper impregnation thermosetting amino resin, composited with solid wood base materials like plywood or core-board. And also, its front is wear-resistant layer while the back is balance layer, then hot press it into grooved and tongued floor. This is a new impregnated paper laminate floor. It also has the same wear-resistant quality as laminate floor, comfort as solid wood floor, and stability as composite board. B. Fire-resistant wood-plastic composite decking board Wood-plastic composite decking board is not the wood floor in the traditional sense, but a composite material, also known as plastic wood. It is formed by high molecular improving and processing natural fiber, such as recycled plastic and wood fiber. It not only has the same advantages as plastic and wood, but alos has certain fire resistance, thus it is a environmentally friendly material with much development potential. C. Fireproof strengthened composite wood floor It is the so-called fireproof and fire retardant floor, fiber board, plywood and chipboard as its base materials. It is coated with fireproof coating and impregnated paper, and after fireproof and fire retardant technical process, it becomes a composite wood floor with some fire retardant level. Its features are more partial to that of laminate floor with stable performance, steady structure and good durability.
Q:How to distinguish the fire rating of rubber and plastic thermal insulation material?
Fire rating grading of external wall thermal insulation materials. 1, China's national standard GB8624-97 divides the combustion performance of building materials external insulation materials into the following grade. Level A: Incombustible materials: Almost no burning materials. Level B1: Incombustible materials: Flame-like material has good fire-retardant effect. In case of fire in the air or at high temperature, it is difficult to fire and doesn't spread quickly, and when the fire source is removed after combustion, it stops immediately. Level B2: Incombustible materials: Combustible materials have a certain flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily leads to the spread of fire, such as poles, wooden frame, wooden beams and wooden stairs,ect. Level B3 : Incombustible materials: No flame-retardant effect, hidhly flammable and high fire risk. 2, The external wall thermal insulation materials could be divided according to the fire rating. 1) thermal insulation material that has the level A combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2), The thermal insulation material that has level B1 combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3), Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU) and polyethylene (PE), etc. The information given is for reference only. Hope it will help you.
Q:What are the requirements on fire resistance period of C-level fireproof glass?
Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance.
Q:which kind of fire bulkhead is better?
Fire bulkhead also known as non-combustible fire retardance board, and it's made by various incombustible material after the scientific pressing, and has good flame resisting properties, it's non-combustible time can reach over 3 hours, high mechanical strength,it has characteristics of non-explosive, water and oil resistance, good chemical corrosion resistance and non-toxic. As for the combustion test of YD-Ba-type inorganic fire bulkhead, it's best to be deformation under the flame temperature of 1000 ℃, the indicators comply requirements of GA161-1997, combustion performance reaches A level standards of GB8624(non-flammable). J fire bulkhead is mainly applicable to the fireproofing protection and fireproofing isolation of cables with all kinds of voltage classes laid on scaffold or bridge. It's widely used in cable project fireproofing and fire retardant in the places with crowded cables, such as various power plants, chemical companys, iron and steel smelting enterprises, mines,etc. It's also the best fireproofing and fire retardant materials of fireproofing and fire retardant projects in indoor decoration of public places, such as large shopping malls, hotels, guesthouses, sports hall, closed clothing market, light industrial markets, theaters and so on. Construction method: Fire bulkhead products can be cut by saw, according to the shape required to be made in the construction site, using steel brackets or expaned anchor bolt to fix it while assembling, steel brackets should be coated with fire-resistant coating for steel structure. You can also use various cable and fireproofing trays made of fire bulkhead, and used in the board gaps.
