(Summary description)Cold-sprayed zinc anti-corrosion coating is a commonly used primer product in industrial heavy-duty anti-corrosion. The anti-corrosion practice tests of many steel structure projects have proved that the anti-corrosion properties of cold-sprayed zinc anti-corrosion coatings containing zinc powder are much better than ordinary anti-rust primers, and The zinc powder in the paint can provide it with a unique cathodic protection effect, which is unmatched by other paints. At present, the best-selling cold spray zinc anti-corrosion coating on the market is the cold spray zinc produced by Zinc Shield, for example, Zinc Shield Cold Spray In Dingzhou Power Plant, Ninghai Power Plant and other projects, zinc anti-corrosion coatings have been compared with foreign brand coatings in the same corrosive environment in the same area for 13 years. It has reduced 2 anti-corrosion overhauls and effectively solved the corrosion of bolt holes, friction surfaces, and welds. Problems, hard core technology, create value for customers.

Cold-sprayed zinc anti-corrosion coating is a commonly used primer product in industrial heavy-duty anti-corrosion. The anti-corrosion practice tests of many steel structure projects have proved that the anti-corrosion properties of cold-sprayed zinc anti-corrosion coatings containing zinc powder are much better than ordinary anti-rust primers, and The zinc powder in the paint can provide it with a unique cathodic protection effect, which is unmatched by other paints.

How does Zinc Shield cold spray zinc anti-corrosion coating produce anti-corrosion protection performance?

1. Cathodic action produces active protection

Zinc shield cold spray zinc anti-corrosion coating zinc-based coating dry film layer zinc content ≥ 95%, zinc purity ≥ 99.995%, the coating electrode potential is -1060mv, almost the same as the electroplating -1100mv, enough to ensure Metal surfaces provide excellent cathodic protection. The results of thousands of hours of neutral salt spray tests prove that even in extremely harsh corrosive environments, zinc-based coatings can still protect the metal surface by sacrificing itself for a long time.

2. The shielding effect produces passive protection

When the zinc shield cold sprayed zinc anti-corrosion coating zinc-based coating is oxidized, a layer of zinc salt will be formed on its surface to provide shielding protection; at the same time, the binder in the coating also provides an additional layer of shielding protection , to slow down the further corrosion consumption of the zinc layer.

What are the advantages of zinc shield cold spray zinc anti-corrosion coating?

1. Zinc shield cold spray zinc anti-corrosion coating is easy to use, flexible in construction, and has a wide application range; it can be coated multiple times, and can be coated with various color topcoats, etc.

2. Zinc shield cold-sprayed zinc anti-corrosion coating has environmental protection performance. With the improvement of the world's environmental protection and hygiene standards, the toxic and negative performance of the coating process has been paid more and more attention; the traditional process of hot-dip galvanizing has been eliminated because it cannot get rid of the environment in its construction process pollute. One of the great advantages of Zinc Shield cold spray zinc anti-corrosion coating is that it does not contain heavy metals such as lead, cadmium, etc., and the content of harmful substance benzene in its solvent is very low, so the coating can be widely used in various industries.

3. Zinc shield cold-sprayed zinc anti-corrosion coating also has excellent anti-corrosion performance. The anti-corrosion performance of zinc-based coating is 10-20 times higher than that of traditional anti-corrosion coatings.

4. Zinc shield cold-sprayed zinc anti-corrosion coating has excellent anti-fouling performance, and zinc-based coating has excellent anti-fouling performance.

5. Strong wear resistance. Zinc shield cold sprayed zinc anti-corrosion coating has excellent wear resistance. Unlike other types of coatings, this coating can produce an electrochemical combination with the metal matrix material, and the coating will neither The flakes fell off, and no air bubbles appeared, and there was no obvious change even at 150°C. Zinc shield cold spray zinc anti-corrosion coating zinc-based coating is characterized by the longer the exposure time, the higher the surface hardness. It has engineering acceptable wear resistance after drying for more than 48 hours. If the surface is top-coated, the wear resistance can be further improved.

Due to the excellent anti-corrosion performance of zinc shield cold spray zinc anti-corrosion coating, zinc-based coating is suitable for all steel structures exposed to the natural environment for a long time, and can replace hot-dip galvanizing, hot-spraying zinc, and aluminum processes; at the same time, it can be applied to The existing hot-dip galvanized and hot-sprayed galvanized components undergo post-maintenance and maintenance. Such as: highway guardrails, power towers, transmission machinery, mining machinery, track facilities, etc. Zinc Shield has focused on the field of cold-sprayed zinc for 16 years. From Mohe, Heilongjiang to Wenchang, Hainan Island, from the Hong Kong-Zhuhai-Macao Bridge to Toutun River in Xinjiang, Zinc Shield Zinc Shield cold-sprayed zinc anti-corrosion coating products have provided long-term, green , Reliable steel protection.

How to achieve environmentally friendly chromium-free passivation of aluminum alloys and other metals

In the passivation treatment process of aluminum alloy surface, countless researchers have done in-depth research. At present, the passivation treatment method of chromate is widely used in the market. The passivation effect of this kind of heavy metal passivation process is acceptable, but it has serious environmental pollution, especially the passivation method such as the use of hexavalent chromium passivation agent, which is also very toxic. In view of this situation, research on chromium-free passivation has also been carried out. Now there are chromium-free passivators that have been put into production. Then, how to achieve the environmental protection of aluminum alloy and other metals without chromium passivation?

Research progress of acrylic emulsion and its application in industrial coatings!

The performance of acrylic emulsion has a great relationship with the structure. Different structural designs provide different performances. Figure 1 shows the common acrylic structural design in current literature reports [3]. Among them, monodisperse is the most common and simplest type. Most acrylic emulsions are of monodisperse type, with simple process, easy-to-control structure, and stable product quality; most of the researches on core-shell structure[4], there are also structures with special functions, such as bimodal structure, blended structure, multi-microdomain structure, multipolar structure, hollow sphere structure [5], polymer-pigment composite structure [6], etc. Under the premise of ensuring good film-forming performance, the structure designed by synthesis can improve certain performance, meet customers' requirements for different performance [7], and expand the performance range and application field of acrylic emulsion.

From

From chromate passivation to chromium-free passivation, what kind of advancement has the galvanized passivation technology experienced?

As a surface-covering protective layer, metals often require additional protective measures to ensure that they meet the corrosion resistance requirements in a certain environment. For example, when zinc is used as a metal surface covering layer, it needs to have sufficient thickness to protect the base metal, mainly relying on the sacrificial anode function of the zinc layer and the dense basic zinc carbonate film formed on the zinc surface in the atmosphere and neutral water environment isolation protection.
