Self-limiting temperature tracing is a kind of heating equipment that can automatically limit its own temperature, which is widely used in industry, civil and other fields. Its quality directly affects its use effect and safety. Therefore, it is of great significance to understand the quality influencing factors of self-limiting temperature tracing for the purchase and use of self-limiting temperature tracing.
1.Conductor material.
The conductor material is the core part of the self-limiting temperature tracing, and its quality directly affects the heating efficiency and stability of the heat tracing. At present, there are two common conductor materials on the market: copper core and alloy core. The copper conductor has good conductivity and high heating efficiency, but it is relatively highThe alloy core conductor is relatively low, but its electrical conductivity and heating efficiency are poor. Therefore, when purchasing a self-limiting temperature tracing, choose the right conductor material according to your actual needs and budget.
2.insulating materials.
The insulating material of the self-limiting temperature trace is also very important, which is directly related to the insulation performance and safety of the heat tracing. At present, the common insulating materials on the market are polyvinyl chloride (PVC), polyethylene (PE) and fluoroplastic (F4). Among them, fluoroplastics have the best insulation performance, but they are also relatively high;PVC and PE are relatively low, but their insulation properties and high temperature resistance are poor. Therefore, when purchasing a self-limiting temperature tracing, choose the right insulation material according to your actual needs and budget.
3.Sheath material.
The sheathing material of the self-limiting heat trace can also affect its quality. The sheath material needs to have good high temperature resistance, corrosion resistance, wear resistance and other properties to ensure that the heat trace can work normally in harsh environments. At present, the common sheath materials on the market are fluoroplastics, silicone rubber, glass fiber, etc. Among them, the sheath material of fluoroplastics has the best performance, but it is also relatively high;Silicone rubber and glass fiber are relatively low, but their performance is also relatively poor. Therefore, when purchasing a self-limiting temperature tracing, choose the right sheath material according to your actual needs and budget.
4.Production process.
The production process of a self-limiting temperature trace can also affect its quality. The high-quality self-limiting temperature tracing has exquisite production technology, the appearance of the product is smooth and flawless, and the conductor and insulation material are tightly combined and not easy to fall off. However, the inferior self-limiting temperature tracing production process is rough, the appearance of the product is rough and flawed, the conductor and the insulating material are not tightly combined, and it is easy to fall off. Therefore, when purchasing self-limiting temperature tracing, you should choose products with exquisite production technology.
In short, there are many factors influencing the quality of self-limiting temperature tracing, and when purchasing and using self-limiting temperature tracing, it is necessary to comprehensively consider factors such as conductor materials, insulation materials, sheath materials and production processes, select products with reliable quality, and install and use them in strict accordance with the product instructions to ensure their normal operation and service life.
