Application Of Carbon Fiber Heating Tube Infrared Drying Technology In Printing Industry

Jan. 16, 2020

Energy conservation, 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 conservation. Today 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 relatively high electric-to-heat conversion rate. In common electric heating products, the electric-to-thermal conversion rate of resistance wire and metal heating pipe is 70%, and the semiconductor heater is about 85%. Up to 95%, different material characteristics and electrical resistance are the fundamental reasons for 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 internal 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 to increase the temperature of the object. 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? Let's introduce the application of carbon fiber heating tube infrared drying technology in the printing industry by using a company's verification effect as an example.

The heating method used by the company's heating equipment was mainly resistance wire stainless steel metal heating tubes and hot air circulation. No carbon fiber infrared heating tube or tungsten wire infrared heating tube with relatively high electricity and heat conversion rate was used. Nor did it absorb infrared light based on 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 with 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 for 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.

The defect of baking and discoloration of paper often occurs during the printing and drying stage before rectification. During this test, because the infrared band matches the ink and the wavelength, the wavelength of the paper does not match well, which solves the problem of paper discoloration. 

The above is the application of carbon fiber heating tube infrared drying technology introduced by Infrared Heating Tube Supplier in the printing industry. I hope to help everyone.
