The difference between good heating wire and bad heating wire is mainly reflected in the following aspects:
1. Material quality
Good heating wires are usually made of high-quality alloy materials, such as nickel-chromium alloy or iron-chromium-aluminum alloy, which have good high temperature resistance and oxidation resistance. Inferior heating wires may use low-quality materials, which may cause them to oxidize or deform easily at high temperatures.
2. Resistivity stability
The resistivity of high-quality heating wire remains stable at high temperatures, helping to provide consistent heat output. Low-quality heating wire may have large fluctuations in resistance when the temperature changes, affecting heating efficiency and safety.
3. High temperature resistance
Good heating wires can withstand high temperatures without softening or breaking, and have a long service life. Poor quality heating wires are prone to melting or cracking at high temperatures, leading to failures.
4. Antioxidant properties
High-quality heating wires will form an effective protective oxide film on their surface to prevent the acceleration of oxidation reactions. Poor-quality heating wires lack this protection and are prone to early damage.
5. Mechanical strength
High-quality heating wires have high mechanical strength and toughness, and can withstand stretching and bending during use. Inferior products are often fragile and easy to break.
6. Security
Good heating wires take safety into consideration during the design and production process, and have good insulation properties to prevent short circuits or leakage. However, inferior heating wires may pose safety hazards and lead to equipment failures or accidents.
7. Manufacturing process
High-quality heating wires usually undergo strict production processes and quality control to ensure that their various performance indicators meet the standards. Poor-quality heating wires may lack such supervision, resulting in unstable quality.
When choosing a heating wire, paying attention to these differences can help users choose a product that is safer, more effective, and has a longer life.
