According to the morphology of zinc flower, what are the main packaging steel strip type?

According to the morphology of zinc flower, what are the main packaging steel strip type? ( 1) No zinc products. Without adding zinc in zinc liquid promote elements, coating without zinc flower formation during solidification, the grain size is very fine, bright and clean level off, the so called no zinc products. Its superior corrosion resistance, coating with good performance, applicable to the various USES of modern industry, is an ideal substrate, caitu is the leading product in a foreign country, is becoming more and more accepted in China. ( 2) Zinc products. Added zinc in zinc liquid promote elements, and zinc coating solidification formed when the beautiful flower. At the beginning of the using exterior performance is good, but the coarse grains, there are slight uneven, coating performance is not very good, especially after a period of time after use will produce black. Abroad has gradually been eliminated, at home also can only be used for civilian production strictly speaking, cannot be used as a caitu substrate. The early lead zinc flower promote element, in order to overcome the black lead change phenomenon in recent years, antimony to add to the formation of zinc. ( 3) The small zinc products. Small spangles product and has no strict definition, generally spend less zinc product called small zinc products. Such as zinc flower diameter greater than 4 mm call big zinc, zinc flowers called little zinc is less than 4 mm in diameter, the small zinc product is kind of composition between zinc products, such as the same liquid zinc containing lead and antimony, in order to overcome the defect of zinc coating performance is bad, when cooling used in a variety of ways to inhibit zinc flowers grew up, eventually forming the small diameter zinc flower. Because it does not like the big zinc with mirror smooth surface, and don't like the first zinc products is bright and clean, so the coating performance, the best is the most ideal caitu substrate. And because the same pot can produce two different products, have big favor with the production enterprise. ( 4) The finishing zinc products. Finishing zinc flowers or small is no zinc in zinc flower, on the basis of the surface again after finishing the galvanized products, make the surface more smooth, more adapt to the need of modern industrial products. Strictly speaking, caitu substrate must adopt the finishing zinc. With the improvement of products, in the future is bound to the extensive use of finishing zinc products.
