The quality of galvanized silk produced by galvanized silk factory varies greatly. As a user, how can we easily and accurately identify the quality of galvanized silk? This is related to the element composition of synthetic galvanized wire. Today, Metal Products Co., Ltd. is here to show you how it works.
Galvanized silk manufacturers on the adhesion requirements of standard galvanized silk coating, the zinc layer of the plating parts should be firmly combined with the basic metal has enough adhesion strength, the hammer test does not fall off, do not bump.
Galvanized wire according to different industrial needs with different requirements, in the smelting installation requirements with different alloying elements, such as chromium, molybdenum, nickel, etc., this kind of jump out of the material is known as alloy Kuang iron. And directly from the ore iron through the furnace galvanized wire, the main composition is oxidation grade, silicon dioxide and some other things, and then add carbon, silicon and other elements in. The resulting material is what we call pig iron.
When the thickness of good galvanized wire and plating parts is 3-4 mm, the zinc adhesion should be less than 460 g/m, that is, the average thickness of zinc layer is not less than 65 microns; When the plating thickness is greater than 4 mm, the zinc adhesion should not be less than 610 g/m, that is, the average thickness of zinc layer is not less than 86 microns; Standard galvanized wire coating must be uniform, galvanized layer is basically uniform with copper sulfate solution test etched five times without exposing iron.
Galvanized silk manufacturers generally use quartz glass heaters. Continuous production does not require heating, but cooling.
Cooling method, not only can be in the groove side row thin wall plastic pipe, through the running water for cooling, also can be used as a titanium pipe temperature control device. In the process of composite plating, it is necessary to stir the plating solution to obtain the composite coating in which the particles dispersed in the matrix metal.
