Product Description

1. Description

Black silicon carbide is produced at high temperature in an electric resistance type furnace with

 quarts sand and petroleum coke as its main raw materials. Its hardness is between fused alumina

and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is sharp and

has electrical and heat conductivity in some degree.

Q:What are the advantages and disadvantages of new external wall fireproof and thermal inuslation matertials?
The new external wall fireproof and thermal inuslation matertials have both the advantages and disadvantages. Advantages: 1)Low requirements on the waterproof, weather resistance and other technical indicators. The dry wall and gypsum plastering mortar, etc. can meet the requirements and can be easily obtained; 2) The inner insulation material are separated by the floor, and construct within a height of only a storey , without erecting scaffold ; 3) In the hot summer and cold winter or hot summer and warm winter area, the inner insulation meets the requirements; 4) The glass beads overcome the shortcomings of expanded perlite, like, large amount water absorption, easy powdering, big volumetric shrinkage in the slurry mixing process, easily leading to post-insulation product performance degradation and hollowing, cracking, and also make up for the defects of polystyrene particles organic materials, like, flammable, poor fire performance, producing harmful gas at high temperatures and anti-aging, poor weather resistance, poor workability and large rebound in construction, ect. Disadvantages of external wall insulation : 1) Since the ring beam, slab and column structure would cause thermal bridges, leading a greater heat loss; 2) It is of low intensity, high water absorption, easy to shrink and crack. The insulation system is prone to cracking, leaking or loss and other common quality problems, especially it is easy to crack at the seams, thus being difficult to exsit as long as the building. 3) It is inconvenient for the users to redecorate and hang ornaments; 4) It takes up indoor used space;
Q:What kinds of refractory materials that can resist 3,000 Celsius degree?
I think that graphite is the only one.
Q:What are the fireproofing materials of the external wall included?
According to the external wall thermal insulation materials, the external insulation materials is in general divided into Class A and Class B. The A class is non-combustible material. The B class is combustible materials. The fire disasters of the CCTV building and Shenyang hotel are both caused by the B level materials. Generally, the A level material will be used, and some prices are even cheaper than the B-grade material. A level is roughly divided into thermal mortar, phenolic foam Board, rock wool board, foam cement board, and so on. I hope my answer will help you!
Q:Which kind of furnace hearth refractory is better?
Coal is acidic medium, so the matched material should be acidic refractories oriented, like silica bricks. For example, the coking coke oven and carbon furnace made of carbon are in reducing atmosphere, so they use silica bricks which have low price and good high-temperature indicators. If the part has special requirements, you can then consider other refractory on request.
Q:What refractories are accessible with ease in daily life?
Basically there have all materials. But it depends on your needs.
Q:How to divide the fire resistant level of construction thermal insulation materials?
Combining three versions of GB8624 (1997,2006,2011), external wall thermal insulation fire rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indexes for specific division. And it is mainly determined in accordance with the national standard GB8624 Building materials combustion levels.
Q:What is the type of heat resistance property of high temperature electric furnace ?
According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃
Q:How can refractory material of the electric furnace be used for longer.
I do not know if you are referring to super high power arc furnace for steelmaking, if you are, I have a easy solution for I have been doing this work.
Q:Why does refractory need to add coarse firstly and then add fine aggregate?
Oh, adding coarse aggregate first is to select good material to make aggregate, and the rest cna be made into fine aggregate. Because if it contains impurities, once being sintered, the appearance will be affected, but fine aggregate does not have this impact.
Q:What are the classifications of refractory? Which category does steel ladle castable belong to?
In addition, it can be divided into refractory, shapeless refractory material. And it can also be divided into acidic refractory, basic refractory and neutral refractory. If you want to know more, you can ask thme. In fact, every company has different refractory clasifications. There are more clasifications in Huaheng.
