Now environmentally friendly
tin bar products are widely used. However, because of its lead-free and environmental protection, the unit price of the product is expensive and the cost is high. A wave furnace needs about 500 kilograms of tin bars per tin furnace, that is, a large amount is invested each time, so the buyer will be careful. Go to inquire and compare, and after several comparisons, I finally selected the cheapest tin bar that complies with EU standards on the surface, but it is also the most likely to waste money, because most buyers do not consider the service life. If the lead content of good-quality environmentally friendly tin bars/wires (wires) is within 100 PPM, it is guaranteed to be made of pure tin ingots. The EU standard of environmental protection tin bar is qualified if it does not exceed 1000PPM. The lead content of pure tin ingots will generally be about 50 PPM, and the lead content of lead-free environmentally friendly tin bars will not exceed 100 PPM.
Lead has the property of depositing, so the lead content will accumulate higher and higher after the tin furnace has been used for a long time. If it is made of recycled materials or other materials, the cost can be reduced by several yuan. If the lead content is high, it may reach three or four hundred PPM. Then a furnace of tin, if the first furnace of tin and lead is put in, the content of tin and lead is high. If it is within 100PPM, it can be used for one and a half years; then if the lead content is around 300 or 400 PPM, the service life can be as long as one year or shorter; if the lead content is close to or exceeds, it is necessary to clean up and replace the tin That is to say, hundreds of kilograms of tin bars must be re-invested. In half a year, how much is the service life of a furnace of tin worth? made up.
Choosing good tin bars, choosing tin bars with guaranteed quality, and choosing tin bars with long-term quality assurance are the most important elements in choosing environmentally friendly products. The longer the service life, the greater the output can be created.
