With this rule a cloud tin production process, dispersed in acetic arsenic, tin, and methyl tin hard head. The slag precipitated by ethylene tin, the hard head after the melting, and the condensate slag (pot residue) refined by the tin-tin fire method are all high in arsenic (see table ); in order to recover the tin and lead , the arsenic must be calcined first. . The calcined soot is enriched with arsenic (see table ) and is purified by electrothermal rotary kiln to be 95% to 99.5% white arsenic series products. The main equipment and technical conditions for the production of white arsenic by Yunxi Yiye are as follows: Â The materials of arsenic roasting and the content of soot produced by the rotary tin smelting 1. Good mechanical performance: compared with other packages, tin cans have much higher strength, good rigidity and are not easy to crack. It can be used not only for small sales package, but also for large transport package.
2. Excellent sealing performance: tinplate cans have superior sealing performance than any other materials. They are resistant to air, moisture, light and taste, and are reliable in sealing, which can protect the product to the maximum extent.
3. Mature process: The production process of tinplate cans appeared very early, its process is quite mature, and its supporting production equipment and tools are also mature, so that the production efficiency can be improved to a greater extent, and the packaging needs of various products can also be met.
4. Fine offset printing: the printing performance of metal materials is far better than that of other materials; Logo, design, text, etc. are very delicate and mellow in printing, which can effectively avoid paint falling and color fading.
