Embodiment 1
[0026] A method for preparing a semi-gold-plated highly reflective infrared heating hollow tube, comprising the steps of:
[0027] S1: Select a ring-shaped hollow transparent glass tube of appropriate specifications, put the cylindrical hollow transparent glass tube in an ultrasonic cleaning agent to clean its surface, take it out, and remove the water on it for later use;
[0028] S2: Put the ring-shaped hollow transparent glass tube into the matching mold so that half of the ring-shaped hollow transparent glass tube is covered by the mold along the center line of its section, and the other half is exposed outside the mold, and then the ring is clamped The hollow transparent glass tube is fixed in the mould;
[0029] S3: the heating device of the vacuum system in the vacuum coating machine is provided with a turntable, and the mold clamped by the clamp in step S2 and containing the annular hollow transparent glass tube is placed on the turntable;
[0030] S4: Vacuumize the v...
Embodiment 2
[0035] A method for preparing a semi-gold-plated highly reflective infrared heating hollow tube, comprising the steps of:
[0036]S1: Select a cylindrical hollow transparent glass tube of appropriate specifications, put the cylindrical hollow transparent glass tube in a hydrofluoric acid solution with a concentration of 3% to clean, so as to clean its surface, then take it out, remove the water on it for later use ;
[0037] S2: The heating device of the vacuum system in the vacuum coating machine is equipped with a turntable, and the two ends of the cleaned cylindrical hollow transparent glass tube are clamped by clamps, and then placed on the turntable;
[0038] S3: Vacuumize the vacuum coating machine so that the vacuum degree in the vacuum coating machine is 8.0×10 -3 MP, at the same time turn on the heating device in the coating equipment for heating, so that the temperature in the oven reaches 180 °C, turn on the turntable in the heating device to make it in a rotating ...
