Matter itself the characteristics of, using process of surface treatment appropriate, impart the more appeal of Tibetan silver texture and expressive force.
According to foreign media, most women for wearing alloy earrings are susceptible to pain redness, blister symptom.Coin,
It can also cause allergic reaction after belt joint even telephone set contact skin.Reason is that these articles contain nickel, industry
Most common skin contact allergin in production.Studies have shown that nickel can be attached to a kind of special immune system protein matter
On, during which participates in the harmful invasion substance of body identification.Nickel can trigger a kind of specific proteins in immune system
Immune response, cause the allergic symptoms such as scorching hot, itch, redness.In the internal of impacted people, immune system can nickel as
A kind of infectious substance, when immune system response is too drastic, body just will appear a series of classical symptoms, such as it is scorching hot, itch, be red
Swollen, blister etc..A series of biochemical reaction can be caused, blood flow increase, tissue leakage, immunocyte is caused to pour in,
Ultimately form infection.
In addition, silver is readily generated a kind of extremely poorly soluble silver salt when encountering hydrogen sulfide gas or sulphion in air,
As long as silver meets the hydrogen sulfide gas or sulphion of several trillion to tens part per trillion in air, just produced in silver surface
Silver sulfide.Because silver sulfide is grey black, with the aggravation of reaction, silver sulfide, which increases, to be thickened, silver surface color just by
Step is by the last blackening of leucismus xanthochromia ash.The source of Air Hydrogen Sulfide is a variety of.It is the excrement of humans and animals first through meticulous
Bacterium generates a large amount of hydrogen sulfide after decomposing, and hydrogen sulfide is also generated after the protein corruption in plant.In addition also contain in the sweat of people
There is sulphur, the sulphur caused by sewage and garbage emission in silver tarnish, especially urban air can be made when it is contacted with silverware
It is more surprising to change hydrogen.
