Application of Carbon Fiber Heating Tube Infrared Drying Technology in Printing Industry

Mar. 04, 2020

Energy saving, emission reduction, and green production are the sacred responsibilities that our generation has entrusted to our generation. For manufacturing companies, we must not only work hard to reduce emissions, but also make more efforts in energy saving. The Carbon Infrared Heater Manufacturer will share with you the case of carbon fiber heating tube radiant heating technology in the printing industry.

Carbon fiber heating tube is a kind of heating component with high electrothermal conversion rate. In common electric heating products, the electrothermal conversion rate of resistance wire and metal heating tube is 70%, semiconductor heater is about 85%, Up to 95%, the difference in material characteristics and resistance is the root cause of the different electrothermal conversion rates.

Carbon Infrared Heater infrared drying technology is a non-contact heating method. Electrical energy is converted into energy by carbon fiber molecular vibrations and reaches the surface of the object through infrared radiation. After reaching the surface of the object, it is absorbed by the object and the temperature of the object rises. The whole process is fast, efficient, energy-saving, and pollution-free. If the infrared wavelength of the carbon fiber heating tube is adjusted to match the infrared wavelength absorbed by the heated object, the heating effect can be greatly improved.

So is there any precedent for the application of carbon fiber heating tube in the printing and screen printing industry? We take a kind of verification effect as an example to introduce the application of carbon fiber heating tube infrared drying technology in the printing industry.

The heating method used by the company's heating equipment was mainly resistance wire stainless steel metal heating tubes and hot air circulation. Carbon fiber infrared heating tubes or tungsten wire infrared heating tubes with relatively high electrical and thermal conversion rates were not used, and infrared rays were not absorbed according to the material resonance. Wavelength to match the corresponding infrared heating tube. When the equipment is remodeled, it is recommended that the customer change to a carbon fiber heating tube of the corresponding wavelength. What is the effect after verification?

Verification scheme: two identical printing presses, one of which uses carbon fiber heating tubes and one uses stainless steel heating tubes. The same products are produced at the same time, and the electricity consumption in one week is recorded.

Test conditions: The parameters of the two devices are the same, and the size, length, shape and power of the heating tube are all the same. Adjust various parameters according to the actual situation during the test.

Test results: After one week of verification, the number of heating tubes of equipment using carbon fiber heating tubes was reduced from the original 32 to 24, the power reduction was reduced from 32 kW to 24 kW, the total power of the equipment was reduced by 25%, and the product quality was not any Impact, production efficiency is not affected.

In the printing and drying stage before rectification, the defect that the paper is baked and discolored often occurs. In this test process, because the infrared band matches the ink and the wavelength, the degree of the paper's wavelength is not high, which solves the problem of paper discoloration.
