    Vaporization and vaporization. The products of these two styles are the same as those of single board. Steam fog type in the place where the curtain string is connected will have a steel pipe to join. In the case of fire, there is water leaking out in these tubes, and the heat of the screen is absorbed, and a rapid cooling effect is achieved.

    And evaporative product in the shade behind will have a tube design, the steel tube with many holes, these holes in the case of a fire water flows down, let the slice can be cool. Although both are capable of meeting the requirements of the specification, there are still defects. For example small hole is very small, if we do not apply for a long time will be prone to rust problem let pore blockage, sprinkler uniformity can not get effective guarantee, and aging is affected by the bad. In the case of vaporized products, the hose structure is very prone to aging problems and can be broken in the case of repeated bending.
