1. dusting manufacture method behind the first bend pipe of a superfine tube diameter fluorescent lamp tube;

  • Comprise process and the process at the inwall coating fluorescent material of described fluorescent tube of a bending process fluorescent tube, the caliber of described fluorescent tube is characterized in that less than 7mm;

    the process of at first carrying out described bending process fluorescent tube;

    Carry out the described process that applies fluorescent material at tube inner wall then;

    Apply in the process of fluorescent material at the inwall of fluorescent tube, in fluorescent tube, pour into phosphor slurry earlier, and the temperature of controlling described phosphor slurry is between 10 degrees centigrade~

    15 degrees centigrade;

    In the fluorescent tube that coats the powder slurry, send into hot blast again;

    The temperature of hot blast is between 100 degrees centigrade~

    130 degrees centigrade, when described fluorescent tube is single U type fluorescent tube, in the step that in fluorescent tube, pours into phosphor slurry;

    The U-shaped opening of described single U type fluorescent tube upwards is provided with, and the positive middle part bottom the U-shaped of described single U type fluorescent tube connects a powder slurry overflow pipe.
