Spetsifikatsioon klassifikatsioon jootmine triikraud ots
Jootmine triikrauad saab kuumutada sisse hapniku puudumine hapniku puudumine - hapnik ei ei ei kuumutamine protsess jootmine triikraud.
The elektriline jootmine triikraud on kuumutatud by the küte nähtus millal vool läbib läbi sulam takistus traat. Elektriline jootmine triikrauad saab olla ligikaudselt jagatud kaheks tüübiks: sisemine küte tüüp ja väli küte tüüp.
The välimine küte tüüp the jootmine triikraud ots at the center of the heating body. Sest the heat source comes from the outside the soldering triik tip, it is called the external heating type. The internal heating type makes the tip the jootmine raud õõnes, ja the heating element is paigutatakse in the cavity, so the volume is suhteliselt small.
Although the oxygen mentioned by the subject does not play any role in the heating process of the soldering iron, it still has a great "contribution" in intertemping with soldering the life the soldering iron.
The kuumutamine traat in a kõrge temperatuur olek tahe oksüdeerub in an aeroobne keskkond. Üle aeg, the oksiid kiht will kukkumine, põhjustamine the kuumutamine traat to be õhem ja kahjustatud, ja lühendamine teenus eluiga jootmine raud. In lisamine, hapnik tahe põhjus an oksiid kiht to ilmuda on pind of sula tina ja metall to keevitatud, blokeerimine the keevitus protsess. Sest see põhjus, jootmine töö on lahutamatu alates voog, ja selle funktsioon on to ennetamine oksüdeerumine.
If it on tõesti võimalik luua an hapnikuvaba keskkond keevitus, see tahe oluliselt paraneb keevitus efektiivsus, keevitus alumiinium saab a tuul, ja at sama aeg see saab pikendada teenus eluiga elektriline jootmine triik.
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.
