Specificatie classificatie van solderen strijkijzer tip
Solderen strijkijzers kan worden verwarmd in de afwezigheid van zuurstof. Omdat zuurstof niet meedoet mee in de verwarming proces van het solderen strijkijzer.
The electric soldering iron is heated by the heating phenomenon when the current passes through the alloy resistance wire. Electric soldering irons can be roughly divided into two types: internal heating type and external heating type.
The external heating type puts the soldering iron tip at the center of the heating body. Because the heat source comes from the outside of the soldering iron tip, it is called the external heating type. The internal heating type makes the tip of the soldering iron hollow, and the heating element is placed in the cavity, so the volume is relatively small.
Alhoewel de zuurstof genoemd door het subject doet niet spelen ene rol in de verwarming proces van het solderen ijzer, het nog heeft een groot " bijdrage" in interfereren met solderen en verkorten het leven van het solderen ijzer.
The heating wire in a high temperature state will oxidize in an aerobic environment. Over time, the oxide layer will fall off, causing the heating wire to beword thinner and damaged, and shorten the service life of the soldering iron. In addition, oxygen will also cause an oxide layer to appear on the surface of the molten tin and the metal to be be weld, blocking the welding process. Voor dit reden, solderen werk is onafscheidelijk van flux, en zijn functie is aan voorkomen oxidatie.
If it is really possible to create an oxygen-free environment for welding, it will greatly improve the welding efficiency, welding aluminum will become a breeze, and at the same time it can extend the service life of the electric soldering iron.
Pay attention to the following points when actually using an electric soldering iron: ①Choose an electric soldering iron with a suitable wattage, and do not overheat the soldering iron, otherwise it will waste electric energy and accelerate the oxidation process and affect welding ②Learn to observe and judge the temperature and fluidity of solder. When the soldering temperature is suitable, the surface will be very bright silvery white and have good fluidity. If the surface turns blue quickly, it means that the temperature is too high, you need to reduce the wattage or use a constant temperature soldering iron. ③Prevent severe vibration. Because the high-temperature-resistant materials used to make soldering iron cores are made of ceramics or mica, they are easy to break and should be handled with care when using them. ④ It is strictly forbidden to use acidic flux when soldering electronic components to prevent corrosion and leakage. The best flux is rosin. However, when welding steel parts, if there is difficulty in tinning, you can use acidic flux to do the tinning work first, then clean it carefully, and finally use rosin to help complete the soldering.
