I often weld electronic componentsWill the electric iron of 30W sublimate the lead and its compounds in the solder into lead smoke? I often weld electronic components and worry about lead poisoning
The key is the temperature of the electric iron, not the power.Can liquefy, will always be a little volatile.Not big, but there must be.
Lead (lead, Pb), grey metal, atomic weight 207.20, the proportion of 11.34, the melting point of 327.5 DEG C, the boiling point of 1620 DEG C, heated to 400 DEG C ~ 5OO, that there are a lot of lead in the air and steam to escape, the rapid oxidation of arsenite lead, and agglutination is smoke. With the increase of temperature of molten lead. Can be further oxidized to lead oxide, four, three lead oxide dilead trioxide, but are not stable, finally dissociates into lead oxide and oxygen.Electric iron temperature is about 300 degrees, although able to melt the solder, but less than the melting point of lead. So even if there is little amount of evaporation lead, will not affect health. Of course, the professional engaged in such work or should pay attention to, lead may also enter the body through the hand or other way, examination may be necessary.
You worry so much, no, you can rest assured. If you're so serious, you probably won't let the production go.
