Detailed Description
Preferred embodiments of the present invention will be described in more detail below. While the following describes preferred embodiments of the present invention, it should be understood that the present invention may be embodied in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 shows a schematic structural diagram of a single cable of a cable temperature rise early warning hoop according to an embodiment of the present invention; fig. 2 shows a schematic structural diagram of a single cable according to the installation state of the cable temperature rise early warning hoop according to an embodiment of the present invention.
As shown in fig. 1-2, a cable temperature rise early warning staple bolt includes:
the staple bolt body, the staple bolt body is the temperature rise body that discolours.
Particularly, the function can be realized by adding a master batch capable of changing color along with temperature change into the material formula of the temperature rise early warning hoop
In this example, the exotherm color changing body is molded from a exotherm color changing thermoset.
Specifically, plastics with temperature-rising and color-changing effects, such as:
