Abstract

The invention provides a method for preparing a fully gold-plated high-reflection infrared heating hollow tube, comprising the following steps: putting a clean hollow transparent glass tube into the vacuum system of the coating equipment, vacuumizing the coating equipment, and opening the vacuum system The heating device; fill the coating equipment with high-purity oxygen and high-purity argon, and then turn on the ion source to treat the surface of the hollow transparent glass tube; conduct evaporation coating on the membrane material, and the coating material is ferric oxide and silicon dioxide. The two are alternately coated, and the half surface of the hollow glass tube along the center line of its section is coated with a reflective film layer or a transmissive film layer; put it into a high-temperature furnace for high-temperature aging; Half of the surface is coated with a transmissive film layer or a reflective film layer; finally, it is aged again to obtain an infrared heating tube with half of the surface having a reflective film layer and the other half having a transmissive film layer. The infrared heating tube of the invention has high heating efficiency and good firmness of the film layer.

Description

technical field [0001] The invention relates to the technical field of infrared heating tubes, and more specifically, relates to a method for preparing a fully gold-plated high-reflection infrared heating hollow tube. Background technique [0002] With the increasingly severe energy crisis, energy conservation and emission reduction has become a social issue of concern. At present, many heating equipment commonly used in production are heated by infrared heating lamps. Infrared heating lamp is a device that uses thermal radiation to make the heated substance absorb energy to intensify molecular motion, thereby increasing the temperature. At present, the general infrared heating lamps improve the heating efficiency of the infrared lamps by coating the lamps with a reflective layer, but due to the low reflection efficiency of the general reflective layer, a large part of the heat energy is lost during use Radiation is lost through the lamp tube, resulting in a waste of energ...
