The service life of nylon tie wraps in normal external environment is about ten years. However, depending on the service environment, it will have a great impact on the service life of nylon tie wraps, and the special service environment can be divided into two types: high-temperature working environment and low-temperature working environment.
The main function of the nylon tie wraps is to fasten and assist in tensioning. When the machine is started, the temperature of the muscles and bones will be about 30 degrees higher than the ambient temperature. In this case, the service life of the nylon tie will also be shortened by 50% to 70%, that is, 3 to 5 years.
When nylon tie wraps work in low temperature environment, the intermolecular tension transfer is blocked due to the slow-down of molecular activity. It is easy to cause brittle fracture of nylon tie wraps, and the specific service life will become very difficult to evaluate due to product quality, product specification and specific temperature.
A remarkable characteristic of nylon tie wraps is water absorption. The properties of nylon materials change greatly after moisture absorption, especially the toughness and elongation at break.
When nylon tie wraps absorb water, the activity of molecular chain increases, which is equivalent to the plasticization of water molecules. Water absorption and dehydration are the two directions of the physical adsorption process. In winter, due to the dry air and low humidity in the air, the nylon tie wraps will gradually lose the moisture contained in the molecule, and become abnormally brittle and easy to break.
In winter, put several humidifiers in the warehouse to supplement the humidity in the air, so that the warehouse will always maintain a certain humidity, so that the nylon tie wraps will not be dehydrated when it is in stock.
If the above conditions cannot be met due to limited conditions, there is another way, that is, inject 5-10ml of purified water into the nylon tie wraps packaging bag two to three days before the nylon tie wraps is used. Please remember that it must be purified water. If it is tap water, scale will occur and the nylon tie wraps will turn yellow.
