Standard and operation of nylon cable ties quality inspection

Standard for quality inspection of nylon cable ties

1. Mechanical properties of nylon cable ties

Nylon cable ties can maintain excellent mechanical properties in wet environments. Nylon cable ties are hygroscopic, and the humidity (water content) increases, resulting in higher elongation and impact strength, but the tensile strength and rigidity gradually decrease.

4. Electrical characteristics and smoldering
Nylon has good insulation, and its electrical rated temperature is less than 105 degrees without affecting its performance, and its resistance reaches 94V-2 level measured by UL.
5. Chemical resistance
Nylon cable ties have excellent chemical resistance, but strong acids and phenolic chemicals have a great impact on their properties.
6. Weather resistance of nylon cable ties to cold weather
In extremely cold and dry weather, nylon cable ties will be brittle and broken when used. At this time, it can be soaked in hot water for one night, and then there will be no brittleness. In addition, in the process of producing nylon cable ties, the process of boiling water can be used to deal with this brittle fracture phenomenon. And in the production process, attention should also be paid to the control of temperature and speed, and do not let the raw material stay in the screw for too long and cause the material to scorch.

Nylon cable tie (cable tie) operation and use
Precautions
1. Nylon cable ties are hygroscopic. Do not open the package before use. After opening the package in a humid environment, try to use it up within 12 hours, or repack the unused nylon cable ties so as not to affect the nylon cable ties during operation and use. Tensile strength and rigidity of the belt.
2. When operating, use the tightening force, which cannot exceed the tensile strength (pull force) of the nylon cable tie itself.
3. The circle diameter of the object to be bundled should be smaller than the circle diameter of the nylon cable tie, and it is inconvenient to operate and the binding is not tightened if it is greater than or equal to the circle diameter of the nylon cable tie.
4. The surface part of the bundled object cannot have sharp corners.
5. There are generally two methods when using nylon cable ties. One is to manually tighten it by hand, and the other is to use a cable tie gun to tighten and cut it. In the case of using a cable tie gun, pay attention to adjusting the strength of the cable tie gun. The specific situation depends on the size, width, and thickness of the cable tie gun to determine the strength of the cable tie gun.
