1. Infrared radiation heating technology has been widely used in high and low temperature dyeing machines, fabric dyeing and finishing, drying and drying of webbing such as safety belts and lifting belts.
1.1 Webbing such as safety belts and slings are composed of polymer compounds, which mainly absorb infrared radiation energy in the mid-to-far infrared band (wavelength 2-15 microns). Carbon fiber infrared heating tube The infrared wavelength is mainly concentrated in the 2.0-15 micron band, which matches the infrared wavelength absorbed by textiles. According to the principle of spectral matching, that is, only when the radiation wavelength of the heating element is consistent with the main absorption wavelength of the heated element, the radiant energy will be absorbed and converted into heat energy.
2. Advantages of twin double-hole or double-row double-hole carbon fiber infrared heating tube
2.1 The power density and radiation area per unit area are greater than single-tube infrared heating tubes
2.2 The strength of the double tube is greater than that of the single tube
High and low temperature dyeing machines for webbing such as seat belts and lifting belts often use twin double-hole carbon fiber infrared heating tubes and double-row double-hole carbon fiber infrared heating tubes. From the cost point of view, the price of twin double-hole carbon fiber infrared heating tubes is 3-5 times that of double-row infrared heating tubes, but the actual effects produced by the two in the drying process are basically the same. Therefore, from the perspective of cost saving, many companies use double-row carbon fiber infrared heating tubes to achieve more than 90%.
