Calculation method for heat transfer area and heat transfer efficiency of polycarboxylate superplasticizer carbon-6 formula and ordinary formula

The carbon six formula and ordinary formula of polycarboxylate superplasticizer mainly rely on relevant thermal calculation formulas and experimental data when calculating heat transfer area and heat transfer efficiency. When calculating, factors that need to be considered include:

• The physical properties of the fluid (such as specific heat capacity, thermal conductivity, etc.).
• The flow rate of the fluid.
• The structural parameters of the heat exchanger (such as the diameter and spacing of the heat exchange tubes).
• The heat loss during the heat transfer process.

Taking a 10-ton reactor as an example, its coil heat exchange area is 20 square meters, the jacket heat exchange area is 30 square meters, and the external heat exchange area is 50 square meters. In this case, the corresponding heat transfer area and heat transfer efficiency can be calculated through thermal calculation formulas based on the specific heat transfer process and usage conditions. The commonly used thermal calculation formulas include:

• The total heat transfer coefficient (U).
• Heat transfer area (A).
• Heat transfer temperature difference (Delta T) of the heat exchanger.

These parameters can be calculated using the following formula:

Q=U⋅A⋅ΔT

Among them, Q is the heat transfer amount,U is the total heat transfer coefficient, A is the heat transfer area, and Delta T is the heat transfer temperature difference.

In order to improve heat transfer efficiency, some effective measures can be taken, such as reducing water temperature to increase heat transfer temperature difference, accelerating cold water circulation speed to improve convective heat transfer coefficient, optimizing the structural parameters of heat exchangers to reduce heat transfer resistance, etc.

In summary, the calculation of heat transfer area and heat transfer efficiency for the carbon six formula and ordinary formula needs to be based on specific usage conditions and requirements, combined with thermal calculation formulas and experimental data. Meanwhile, by taking some effective measures, the heat exchange efficiency can be further improved to meet the actual needs of the production process.
