Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0020] When processing high-corrosion-resistant zinc strips, take an appropriate amount of stainless steel composite zinc strips, and remove iron oxide scale, dirt and surface impurities from the stainless steel composite zinc strips to be treated; Gun heating, the heating temperature is 1000-1205 ℃, so that the entire zinc strip interface is evenly heated, immediately adopt low-temperature tempering after heating, tempering temperature 180-260 ℃, stand for 2-4h for later use; pass the zinc strip successively through deionized water, Wash with ethanol and 5vol% sulfuric acid, then wash with deionized water for a second time to remove residues, and finally air-dry; add pure water to the container, add silane coupling agent, KH792 silane coupling age...

Abstract

The invention discloses a machining technology of high corrosion resistance zinc strip. The machining technology of the high corrosion resistance zinc strip comprises the following steps that a properamount of stainless steel composite zinc strip is obtained, and iron scale, dirt and surface impurities are removed from the stainless steel composite zinc strip to be treated; and the stainless steel composite zinc strip with impurities removed is heated by using a flame lance, the heating temperature is 1000-1205 DEG C so that the interface of the whole zinc strip can be uniformly heated, and low-temperature tempering is adopted immediately after heating, the tempering temperature is 180-260 DEG C, and standing is kept for 2-4h for later use. According to the machining technology of the high corrosion resistance zinc strip, impurity removal, purification treatment, heating, low-temperature tempering, sulfuric acid cleaning and other process steps are carried out on the stainless steel composite zinc strip, so that the stainless steel composite zinc strip is subjected to secondary utilization, a pure zinc strip finished product is prepared, corrosion protection treatment is carried out on the surface of the prepared zinc strip, the wear resistance of the zinc strip is greatly improved, and the service life of the zinc strip is prolonged.

Description

technical field [0001] The invention belongs to the technical field of zinc strip processing, and in particular relates to a processing technology of a highly corrosion-resistant zinc strip. Background technique [0002] Zinc strip is a kind of sacrificial cathodic protection material. The main material is metal zinc. When the corrosion battery system is working, another electrode wire is connected, and the potential of this electrode is relatively negative. At this time, the original corrosion battery and this electrode are formed. A new macro electro. From the electrochemical principle, the negative electrode is the new battery, and the so-called cathode is the original corrosion battery. Provide a cathodic current from the electrolyte to the protected body, and then the protected body will perform cathodic protection, and cathodic protection will be completed. With the continuous consumption of materials and continuous flow of current, there is a sacrifice; [0003] Ho...
