Dicarb is short for dicarboxylic acid, which is a type of organic acid with two carboxylic acid functional groups.

• Dicarboxylic acids are commonly used in the production of polymers, resins, and pharmaceuticals.

• Examples of dicarboxylic acids include oxalic acid, malonic acid, succinic acid, and adipic acid.

• Dicarboxylic acids can be synthesized through various methods, including oxidation of alkenes and hydrocarbons.

• Dicarboxylic acids have a wide range of applications, includin...read more

6.67% carbon is added in the Iron Carbon Diagram to achieve the desired properties of steel.

• The addition of 6.67% carbon allows for the formation of a eutectoid composition, which results in the formation of pearlite.

• Pearlite provides a desirable combination of strength and ductility in steel.

• Higher carbon content can lead to the formation of brittle phases like cementite, reducing the mechanical properties of the steel.

• Lower carbon content results in a ferrite-pearlite micro...read more

Different types of hardness include scratch hardness, indentation hardness, and rebound hardness.

• Scratch hardness is the resistance of a material to scratching or abrasion.

• Indentation hardness is the resistance of a material to permanent deformation caused by a constant load.

• Rebound hardness is the ability of a material to absorb energy and return it upon impact.

• Examples include Mohs scale for scratch hardness, Rockwell scale for indentation hardness, and Shore scale for rebo...read more

No, Phase Diagram and Equilibrium Diagram are not the same.

• Phase Diagram represents the relationships between different phases of a substance at different conditions of temperature and pressure.

• Equilibrium Diagram, on the other hand, represents the equilibrium conditions between different phases of a substance at a specific temperature and composition.

• Phase Diagram is a broader concept that includes Equilibrium Diagram as a specific case.

• Equilibrium Diagram is a subset of Pha...read more

The full form of HRC scale is Rockwell Hardness Scale C.

• HRC stands for Rockwell Hardness Scale C.

• It is a measure of the hardness of a material, commonly used in metallurgy.

• The HRC scale is often used to determine the hardness of steel.

• Higher HRC values indicate harder materials.

Polymer percentage can be checked using techniques like thermogravimetric analysis, Fourier transform infrared spectroscopy, and nuclear magnetic resonance spectroscopy.

• Use thermogravimetric analysis to measure the change in weight of a sample as it is heated, allowing for calculation of polymer percentage based on weight loss.

• Utilize Fourier transform infrared spectroscopy to analyze the chemical bonds present in a sample, providing information on the types of polymers prese...read more

Coil gape can be checked using a feeler gauge to measure the distance between the coils.

• Use a feeler gauge to measure the gap between the coils

• Ensure the coil is at room temperature before measuring

• Check for any irregularities or inconsistencies in the coil gape

Core hardness can be checked using various methods such as Rockwell hardness test, Brinell hardness test, and Vickers hardness test.

• Use Rockwell hardness test for quick and easy measurement

• Use Brinell hardness test for larger core samples

• Use Vickers hardness test for small or thin core samples

• Ensure proper calibration of testing equipment

• Follow standard testing procedures for accurate results

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally iron.

• Used for smelting iron ores to produce iron

• Consists of a furnace chamber with a tuyere at the bottom for air supply

• Operates at high temperatures to melt the iron ore and extract the metal

• Commonly used in the steelmaking industry

Rotary kiln is a cylindrical vessel used for calcination, drying, and sintering of materials.

• Consists of a long, rotating cylinder with a slight incline

• Materials are fed into one end and heated as they move towards the other end

• Used in various industries such as cement, lime, and mineral processing

• Can reach temperatures up to 3000°F (1650°C)

• Can be designed for both continuous and batch processing
