Without further ado, let’s go straight to the practical knowledge. Those who are interested can read down slowly, while those who are not interested can draw straight to the end and see the conclusion!
Comparison between Level 1 Energy Efficiency Hot Melt Kettle and Level 3 Energy Efficiency Hot Melt Kettle
1、 The required heat=specific heat capacity of the substance x mass x temperature to be heated (Q=C * M * Δ T). The specific heat capacity of the substance can be measured, assuming that the specific heat capacity of the hot-melt marking coating is approximately 2.3 joules/gram/degree Celsius (slightly different manufacturers of coatings). Assuming the heat required to heat 1000KG of hot melt coating from 20 ℃ to 200 ℃ is: Q=2.3 joules/gram/degree Celsius * 1000 kg * (200 ℃ -20 ℃)=414000 joules=414 kilojoules. The heat required to heat 1000KG hot melt coating from 20 ℃ to 200 ℃ is 414 kilojoules. Converted to how much liquefied petroleum gas is needed=required heat (414 kilojoules)/calorific value of liquefied petroleum gas (46 kilojoules/kilogram)=9 kilograms. The thermal efficiency of the first level energy efficiency hot melt kettle is approximately 65%, which requires 13.8 kilograms of liquefied gas. The thermal efficiency of the second level energy efficiency hot melt kettle is approximately 55%, which requires 16.3 kilograms of liquefied gas. The thermal efficiency of the third level energy efficiency hot melt kettle is approximately 45%, which requires 20 kilograms of liquefied gas
2、 Based on the above calculations, it can be concluded that the liquefied petroleum gas required to heat 1 ton of paint to 200 ℃ in a first level energy-efficient hot melt kettle saves 6.2 kilograms compared to the liquefied petroleum gas required in a third level energy-efficient hot melt kettle. The annual usage of 1000 tons of paint can save 62 yuan x 1000 tons=62000 yuan. Do you still have to worry about which manufacturer’s hot melt kettle is cheaper?
The above interested friends can verify on their own. Perhaps no one has ever spent time and energy researching in this area before, but now facing such vicious market competition, people have to reflect and study. The process of bad money driving out good money is becoming increasingly serious. How can good money survive? Should people who produce good currency change their mindset?
