Embodiment 1
[0020] Embodiment 1, a method for making a dartboard based on a target wire of the present invention, comprising the following steps:
[0021] Step a. Strip forming: use recycled drawing grade polypropylene PP and heavy calcium carbonate as raw materials, mix recycled drawing grade polypropylene PP and heavy calcium carbonate, and send them to the strapping machine equipment to make strapping tape. Sheet-shaped strips; among them, recycled drawing grade polypropylene PP is 70% and calcium bicarbonate is 30%;
[0022] Step b. Strip tearing: multiple needles arranged diagonally together penetrate the strip along the width direction of the strip, and then let the strip move along the direction of the needle, so that the strip is torn along the direction of motion According to the fineness requirements of the filaments, the strips can be torn by the dislocation method of multiple rows of oblique needles, so that the strips are torn into thinner strips along the length direction, whi...
Embodiment 2
[0030] Embodiment 2, the manufacturing method of a dart board based on target wire of the present invention is different from Embodiment 1 in that, in the raw materials of recycled wire-drawn grade polypropylene PP and heavy calcium carbonate, recycled wire-drawn grade Polypropylene PP is 50%, calcium bicarbonate is 50%.
Embodiment 3
[0031] Embodiment 3, a method for making a dart board based on target wire of the present invention is different from Embodiment 1 in that, among the raw materials of recycled wire-drawn grade polypropylene PP and heavy calcium carbonate, recycled wire-drawn grade Polypropylene PP is 75%, calcium bicarbonate is 25%.
