Jak identifikovat kvalitu odporového drátu?

The service life of the resistance wire is related to the use time of the overall product, and it is also the most concerned issue of the merchants. However, most of the small manufacturers do not understand the heating products and think that the low price does not necessarily lead to the bad quality, which leads to the appearance of quality and brand in the final product In crisis, the quality of resistance wire can be identified through the following points.

1.Product temperature resistance performance: The common heating wires in the market are generally divided into silicone heating wires, PVC heating wires, and Teflon heating wires. In terms of temperature resistance, they are definitely the first choice for Teflon, but the expensive price makes buyers Unbearable, PVC material is notoriously not resistant to high temperatures. A higher temperature will cause the outer skin to melt. Therefore, PVC is definitely not an option. Silicone is a common high-temperature insulating material, the outer skin is soft and elastic, and the working temperature is The temperature is between minus 60 degrees and 200 degrees, the price is cheap, and it is impossible to use recycled materials for production. It is recommended Použití tohoto topného drátu .

2. Ohýbání Performance: Jak se říká, to, za co platíte, je to, co platíte za . Dobré produkty nelze oddělit od dobrých materiálů . Výběr topného drátu je klíčem k životu, Constanding-Chromium, Constantor-NICKEL, CONTANTAN, CONSTANAN, CONTANTON, CONTANTAN, CONTANTAN, CONTANTON, CONTANTAN, CONTANTAN, CONTANTAN, CONTANTAN, CONTANTAN, CONTANTAN, CONTANTAN, CONSTANAN, CONSTANAN, CONSTANN atd. ., ale konečný materiál je stále odlišný . Produkty v jakémkoli odvětví jsou dobré nebo špatné . Podle standardu UL, pouze topný vodič s ohybovým testem větší než 25 000krát může splňovat standard produkční technologie UL .

3. Problém vzhledu: Vzhled topné linie bez problémů by měl být hladký a jasný .
