What is the difference between technical grade and commercial grade chemicals?

User Avatar

Asked by Wiki User

Technical grade chemicals are typically higher in purity and are used in laboratory settings for research and analysis. Commercial grade chemicals, on the other hand, are more commonly used in industrial applications and may have slightly lower purity levels but are still suitable for their intended purpose.

How does the structure of a thermoplastic differ from a thermosetting plastic?

User Avatar

Asked by Wiki User

  • Once 'set' these plastics cannot be reheated to soften, shape and mould.

  • Thermosetting Plastics are made up of lines of molecules which are heavily cross linked. It creates a rigid molecular structure.

  • They may be heated the first time and shaped but they become permanently stiff and solid.

  • Unlike thermoplastics, they retain their strength and shape even when heated.

How burden calculated in blast furnace?

User Avatar

Asked by Shivanandi

The burden in a blast furnace refers to the materials added to the furnace for the iron-making process. The burden typically includes iron ore, coke, and limestone. The burden calculation takes into account the proper proportions of these materials to achieve efficient iron production and maintain the desired chemical and physical balance within the furnace. Various factors, such as the quality of the materials and the operating conditions, influence the burden calculation in a blast furnace.

What is specfic weight of granulated slag with water from blast furnace?

User Avatar

Asked by Wiki User

The specific weight of granulated slag with water from a blast furnace can vary depending on the properties of the slag and the amount of water added. However, typically the specific weight of granulated slag with water would be higher than the specific weight of water alone due to the presence of the solid slag particles in the mixture.

Does iron ore slag sink to the bottom of the blast furnace?

User Avatar

Asked by Wiki User

Yes, iron ore slag is denser than molten iron and other materials, so it sinks to the bottom of the blast furnace. This allows the molten iron to be tapped off from the top while the slag is removed from the bottom.

What kind of fire bricks are used for molten blast furnace slag?

User Avatar

Asked by Wiki User

High alumina fire bricks are commonly used in applications involving molten blast furnace slag due to their high refractoriness and resistance to thermal shock. These bricks are able to withstand the high temperatures and harsh conditions of the slag without deforming or deteriorating quickly.

Is polystyrene thermosetting or thermoplastic?

User Avatar

Asked by Wiki User

Polystyrene is a thermoplastic, which means it softens when heated and can be molded into different shapes but retains its solid structure after cooling.

What is the differences between charges and expenses?

User Avatar

Asked by Wiki User

Charges are typically one-time fees or costs associated with a specific transaction or service, while expenses are ongoing costs incurred to operate a business. Charges can be variable and impact specific transactions, while expenses are usually fixed or recurring costs necessary for day-to-day operations.

The middle region of the blast furnace called?

User Avatar

Asked by Wiki User

The middle region of the blast furnace is called the bosh. It is where most of the chemical reactions, such as the reduction of iron ore and the formation of slag, take place. The bosh is a critical part of the furnace for producing molten iron efficiently.

How does one neutralize methane in a lift station?

User Avatar

Asked by Wiki User

Methane gas can be neutralized in a lift station by installing an anaerobic digester or a biofilter system. These systems utilize bacteria to break down the methane gas into less harmful substances such as carbon dioxide and water. Regular maintenance and monitoring of the system are necessary to ensure effective methane neutralization.

1.8N equals to how many kPa?

User Avatar

Asked by Wiki User

To convert Newtons to kiloPascals, you need to divide by the area in square meters over which the force is applied. Kilopascals are a unit of pressure, so the conversion depends on the area involved.

Why does the glucose molecule have to be broken down step by step?

User Avatar

Asked by Wiki User

The glucose molecule needs to be broken down step by step through processes like glycolysis to extract energy in a controlled manner, which can be efficiently stored and used by the cell. This gradual breakdown ensures that the maximum amount of energy is captured and converted into a form that the cell can easily utilize. Additionally, step-by-step breakdown helps regulate the release of this energy to prevent wasteful loss or damage to the cell.

What do you call the type of engineer that designs bridges?

User Avatar

Asked by Wiki User

civil engineers, structural engineers, and architects are the main bridge builders.

What is the length in feet of a wave whose frequency is 268 Hz?

User Avatar

Asked by PlainOldD

The length of the wave can be calculated using the formula: speed = frequency x wavelength. The speed of a wave in air is approximately 343 meters per second. Converting 343 m/s to feet/s, we get approximately 1125 ft/s. Using the formula speed = frequency x wavelength, we can solve for wavelength: wavelength = speed / frequency. Therefore, the wavelength of a wave with a frequency of 268 Hz is approximately 4.2 feet.

What is waterproof cement?

User Avatar

Asked by Wiki User

Waterproof cement is a type of cement that is formulated to resist water penetration and moisture ingress. It is commonly used in projects where water resistance is important, such as basements, swimming pools, and other water-retaining structures. Waterproof cement typically contains additives that enhance its resistance to water and help prevent water damage.

How do you check the performance of wind tunnel?

User Avatar

Asked by Wiki User

To check the performance of a wind tunnel, you can measure parameters such as airflow velocity, turbulence levels, pressure differentials, and flow uniformity. These measurements can be collected using instruments like pitot tubes, anemometers, pressure sensors, and flow visualization techniques. Regular calibration and comparison with established standards are also important to ensure accurate performance evaluation.

The hardest known natural material is?

User Avatar

Asked by Wiki User

Diamond is typically considered the hardest known natural material due to its exceptional hardness and durability. It ranks 10 on the Mohs scale of mineral hardness, making it difficult to scratch or chip.

What are the different zones in blast furnace?

User Avatar

Asked by Wiki User

The blast furnace is typically divided into three main zones: the top zone (stack), the middle zone (bustle), and the bottom zone (hearth). The top zone is where raw materials are charged into the furnace and combustion of coke occurs. The middle zone is where gases and heat transfer occurs, and the bottom zone is where molten metal is collected.

Symbol equation for the reaction that provides heat to maintain the temperature of the blast furnace?

User Avatar

Asked by Wiki User

The symbol equation for the reaction that provides heat to maintain the temperature of the blast furnace is:

C(s) + O2(g) -> CO2(g)

This reaction involves carbon (in the form of coke) reacting with oxygen to produce carbon dioxide, releasing heat energy in the process.
