Model No

BA-20#

Brand name

BA,CHINA

 

 

 

 

Description

Black Silicon   Carbide is produced with high   temperature in a electric resistant furnace from a mixture of quartz sand and   petroleum coke.

 

Its hardness is between that of fused   alumina and synthetic diamond and mechancial intensity of it is also greater   than that of fused alumina. It is brittle and very sharp and  has a   certain degree of electrical and heat conductivity.

 

Black silicon carbide is typically used for   working on cast iron ,non-ferrous metals, stone, leather, rubber, and other   materials which requires sharp cutting characteristics. The mineral is also   used widely as a refractory material and metallurgical additive. 

 

 

 

 

Advantage

1.          raw   materials are of high quality: pure silicon carbide, guaranteeing the   products’ good quality.

2.          sharp   knife-edge, having cutting function.

3.          Centralized   and uniform particle size distribution

4.          electrical   conductivity 

5.          heat   conductivity

6.          chemical   stability

7.          high   thermal conductivity,

8.          low   expansion coefficient

9.          good   abrasion-resistance

Q:What's the classification of flameproof glass, the refractory time of fireproofing glass.
there mainly are five fireproofing glasses, the first one is laminated composite fireproof glass, the second one is wired fire-resistant glass, the third one is special fireproofing glass, the fourth one is hollow fireproof glass,the fifth one is high strength monolayer cesium potassium fireproof glass.
Q:I wanna ask what are the acidic refractories?
Usually, acidic refractory refers to a kind of refractory which contains a amount of silicon dioxide. There are the following: (1) silica brick with stronge acidity, unshaped silicious refractory, quartz glass and fused silica combined products; (2) semi-silica refractory with moderate acidity and pyrophyllite refractory; (3) clay-based refractory with weak acidity. The main features of the acidic refractories is resistant to the erosion of acidic substances (acidic residue) in high temperature, but is easy to react with alkaline material (basic slag). zirconite fireproofing material and silicon carbide as the special acidic refractories refractories are also in this category.
Q:What is the the best ratio of mortar in refractory cement?
The ratio of refractory cement are: M10 the ratio of cement and mortar: cement: Sand= 346kg: 1631kg M7.5 ratio of cement and mortar: cement: Sand =274kg: 1631kg M5 The mix proportion of cement and mortar: cement: Sand = 209kg: 1631kg M10 mix proportion of composite mortar: cement: Sand: Lime =306kg: 1600kg: 29kg M7.5 mix proportion of composite mortar: cement: Sand: Lime =216kg: 1600kg: 64kg M5 The mix proportion of composite mortar: cement: Sand: Lime =205kg: 1600kg: 100kg
Q:What kind of fireproof material is used for steel structure?
Brushing or spraying the coating on the surface of steel structure to prevent burning and insulate heat. It also prevents undermining the rolled steel from rapid temperature elevation and avoid collapse of building for lose of supporting capacities. Agglutination material are classified as fireproof coatings for steel structures which is solvent based and Water-based steel structure fire retardant coatings. Fireproof coatings for steel structures which is solvent based are subdivided into fireproof coatings for steel structures which is solvent based with low benzene content and fireproof coatings for steel structures which is solvent based with high benzene content (TVOC≤600g / L, benzene ≤5g / kg). It can be divided by thickness. ultra-thin (CB) fireproof coatings (coating thickness ≤3mm), thin (B) fireproof coatings (3mm & amp; lt; coating thickness ≤7mm) and thick (H) steel structure fire retardant coating (7 mm & amp; lt; coating thickness ≤45㎜).
Q:What is the material composition of the new fire-resistant coating?
New fire retardant coating materials are produced by non-toxic expanding materials and special process, with no pollution. Use natural bite when installing, without using the formaldehyde and other toxic glue. It consists of a variety of organic matters, so it adapts to the natural environment, with long time of fire-resistant; The fire-resistant time for new fire retardant module is up to 4 hours or more, three hours more than the standard prescribed by the state. It is composed by the specially formulated materials, with no flying smoke, good heat insulation effect, fast heat dissipation, scientific and rational design, easy using and no falling off and long period of effective.
Q:what is the material of fixed first rate fire resistant window?
Fixed first rate fire resistant window is produced by the steel sash windows, steel casement, fireproofing glass. Fireproof windows, is composed by steel window frame, steel casement, fire-proofing glass. it refers to the window which can isolate and stop the fire spreading. The fire window product is named after the main material of window frame and the window casement, window frames is made of steel, casement is made of wood or the sash frame is made of wood and the casement is made of fire window.
Q:How many grades of fire rating are there for interior decoration materials?
It can be divided into structural material and base material based on materials. It can also be divided into flammable, flame retardant and non-combustible materials based on fireproof types. There is no fire rating for materials. But lengths of time of flammability limits are different.
Q:How is refractory material made?
It is made from polyester.
Q:What are the meanings of azs, 34% and ec in fused brick?
The fused brick, also called zircon corundum brick, is shorted as AZS for three chemical components in Al2O3-ZrO2-SiO2 ternary diagram. I don't know the meaning of EC.
Q:What are the differences between intensive refractory busway and other busways?
Compact busway is named according to its structure, and fire-resistant busway is named after its uses. Compact busway especially refers to busway which is closely laminated between phases and between phase and shell, and use thin insulating material to achieve the insulation result. suitable for power supply system of alternating current three-phase four-wire, three-phase five-wire system, frequency of 50 ~ 60Hz, rated voltage up to 690V, rated operational current of 250 ~ 5000A, as auxiliary equipment for mining, enterprises and high-rise buildings, and especially suitable for the transformation of workshop and old enterprises. Fire-resistant busway is composed of shell coated with fire retardant paint, bus line wrapped with fire-resistant mica tape and bracket made by refractory insulating material. Bracket has a plurality of grooves where inbedding the bus line and fixed it. There is a busway connecting box at one end of the busway and there is a bus line splitter box in the busway. Fire-resistant busway has excellent insulation properties, which can not only be used continuously in a normal environment, but also can be used in the fire environment continuously for more than one hour, suitable for high-rise buildings and important facilities, replacing the fire-resistant cables to transmit and distribute power .
