Antistatic non-woven fabrics 10 are arranged inside the surface positioning grooves 9, and PE antistatic plastic sheets 11 are glued to the surface of the antistatic non-woven fabrics 10. A dispersion component is arranged on the side wall of the polyethylene water bag 1 to assist the internal liquid of the polyethylene water bag 1 to quickly spray liquid to the surrounding area in a multi-directional and three-dimensional manner to reduce dust in the blasting state. The top of the PE antistatic plastic sheet 11 is kept flush with the outer wall of the polyethylene water bag 1, and the connection between the polyethylene water bag 1 and the PE antistatic plastic sheet 11 is glued by glue. The surface positioning grooves 9 are symmetrically arranged on the outer wall of the polyethylene water bag 1, and the surface positioning grooves 9 are arranged as a rectangular open groove structure;

[0039] In conjunction with the accompanying drawings Figure 1-6 As shown, when in use, the thermoplastic interface 6 set on one side of the polyethylene water bag 1 is sleeved with the polyester tube belt 5, as shown in FIG. Figure 1-2 As shown, by passing the heat insulation board through the polyester tube belt 5, cooperating with the external heating equipment, the polyester tube belt 5 and the polyethylene water bag 1 are thermoplastically closed at the thermoplastic interface 6, so that the polyethylene water bag 1 and the polyester tube belt 5 are an integrated structure after production, and the polyester docking interface 2 set at the end of the polyester tube belt 5 and the polyester bag mouth 4 is used for filling liquid, wherein the bottom end of the polyester tube belt 5 is close to the bottom end of the polyethylene water bag 1, further buffering the flow direction of the liquid into the polyethylene water bag 1, and as the polyester bag mouth 4 and the polyester docking interface 2 are injection molded with the same material as the polyester tube belt 5 After the water injection is completed, the internal space is sealed by tying around the polyester docking port 2 and the polyester bag opening 4 to prevent liquid discharge.
