AIR DUCT AND PAPER THEREFOR |
摘要 |
An air duct is disclosed which includes a tubular member formed from a metal sheet. A paper is disposed around an outer periphery of the tubular member for preventing condensation droplets condensed on the tubular member from dripping, and an adhesive is interposed between the tubular member and the paper to adhesively secure the tubular member and the paper. Furthermore, a paper for an air duct, adapted to be secured to an outer periphery of the air duct, is disclosed. The paper is produced from a material including a papermaking pulp and is characterized by the following: a wet strength of at least 0.3 kgf/15mm, a critical value for dripping of water droplets of at least 45 g/m2, and a basis weight of 40 to 5000 g/m2.
