SolderingIs there any poison? Is it highly harmful to the human body?

In fact, we still need to pay attention to this aspect in our work. Generally, soldering is divided into lead-free and leaded types. If we don't frequently exceed the workload, the problem won't be too big.

What are the harms of soldering to the human body?

The main manifestations of the human nervous system are neurasthenia, polyneuropathy and encephalopathy. Mild cases may present with general digestive tract symptoms, while severe cases may experience abdominal colic. Other systems Lead damage to the kidneys is more common in acute, subacute lead poisoning or severe chronic cases, presenting with amino acid proteinuria, decreased red blood cells, white blood cells, casts and renal function, suggesting toxic nephropathy, accompanied by hypertension. Female workers are more sensitive to lead, especially during pregnancy and Lactation period Can cause Infertility , Abortion Premature birth, stillbirth and infant lead poisoning. Male workers can cause a decrease in sperm count, weakened motility and morphological changes. In addition, it can also cause hypothyroidism.

Is lead-free solder toxic?

Common tin and lead alloys, which have good electrical conductivity and low melting points, are used in the welding process.

All tin contains lead. Nowadays, most of our enterprises use lead-free solder wire. Generally speaking, lead-free processes do not cause lead fumes to exceed the standard. However, soldering still has other hazards, such as flux (rosin-like substances) which has certain risks. It depends on the specific situation. If the tin used is lead-containing, it will be somewhat harmful to the body.

Then how to prevent it? As follows:

1Take a break for a while General repair1Take a break during the hours.15About minutes Relieve fatigue Because the resistance is the weakest when one is tired

2Smoke less. Drink plenty of water In this way, most of the absorbed harmful substances can be excluded during the day

3, Drink mung bean soup or honey water before going to bed This can reduce internal heat It is helpful for one's mood Moreover, mung beans and honey can eliminate a large amount of lead absorbed And radiation!

4.Radiation should be avoided as much as possible Make more use of your personal phone (PHS) Use mobile phones less. Use your mobile phone when you can't go out Here It is suggested that everyone

5You can make the soldering iron brighter Use as much as possible.PPDThe welding head So the temperature has been reached Less welding oil and rosin can be used Reduce the harm to the body

6When the soldering oil starts to smoke, try to tilt your head a little to the side When washing the sky with water, you should also tilt your head a little to the side Try to hold your breath.

7Use less thinner than thinner Use more alcohol. , Brushing with alcohol for a longer time will have about the same effect ~

8Wash your hands thoroughly

9Before going to bed Take a bath Try to go to bed early and get up early Ensure adequate sleep As long as you sleep well Impurities can basically be excreted along with the body

10A novice is just entering the industry Practice handicrafts You can practice with a mask on Newly trained hands tend to practice for a relatively long time every day It is the period when the harm to the body is the greatest So masks are a must!
