ZINC STRIP
zinc bar, with zinc, zinc powder, zinc and other residue.  Zinc is a basket of white metal.  Density  7.14 grams  / Cubic centimeter, the melting point of  419.5 ℃  .  At room temperature, and more brittle; 100 ~ 150 ℃, softened; over  200 ℃  , And Biancui.  Zinc metal, chemical symbol Zn.  Part II is a chemical periodic table of ethnic group elements, is one of the six basic metals.  Zinc is a white slightly blue-gray metal, a metallic luster, in the nature of the multi-state presence to sulfides.  Mohs hardness of 2.5, its crystal structure of the six-strong stability, can not be changed, but can be enhanced.  Soft zinc, lead and tin than just hardware, Zhanxing than small lead over the big iron; Zhanxing than the small copper and tin.  Fine crystal of zinc in zinc than the coarse-grained crystal Kun easy rolling and spinning, zinc at room temperature will not be dry air, non-carbon dioxide, or dry air of oxygen by oxidation.  However, in contact with the wet air, its surface will gradually be oxidized to form a dense gray alkaline zinc carbonate wrapped its surface, the protection of internal cease to be eroded, not soluble in pure pure zinc sulfate or hydrochloric acid, but if zinc in There will be a small amount of impurities dissolved by the acid.  Therefore, the general merchandise zinc easily be dissolved by the acid and alkali can also be dissolved, standards of quality according to national acceptance.  I may be responsible for door-to-door.  Prices are lower than market prices, hoping to work with you to be happy, Yuanyuguangda customers to establish long-term business relationships, integrity-based company, the customer first, won the trust businessmen are welcome to call on Qia.
