Sand blasting zinc shot

Ordinary zinc pellet ingredients:

Zinc Shot Zinc Alloy Shot

Zinc pellets Cut pellets

Main technical indicators of zinc wire cut shot:

1. Pure zinc pellets:
pure zinc pellets use 0# distilled zinc deposits (zinc content ≥ 99.995%), zinc balls produced by international advanced production and processing technology, the size is 0.3mm-5.0mm, hardness: HV35-45, Density: 8.4g/cm³. is widely used in:

1. It is used for shot blasting treatment of various metal surfaces so that it has a higher service life.

2. Advanced galvanizing, has the following characteristics: it moves the fatigue source from the surface to the subsurface; it reduces the electrode potential and polarization current; it increases the corrosion resistance.

3. Addition for metal smelting

Chemical composition:

Because the specific gravity of zinc is close to that of iron and its hardness is low, it can remove large burrs without damaging the product, and unlike aluminum abrasives, the risk of dust explosion and fire is extremely low, so it can be used as a deburr for aluminum products The use of safe sandblasting materials.

The main purpose:

(1) Deburring and cleaning of various aluminum and zinc die castings.

(2) Deburring of various products.

(3) Stripping and cleaning of various coatings.

High hardness zinc shot: uniform composition, pure particle size, moderate hardness, long life. The specific gravity is close to that of steel, and the hardness is low, so it can not only remove large burrs without wearing the surface of the product, but also form an anti-corrosion and anti-rust layer on the metal surface. Unlike aluminum-based abrasives, dust has an extremely low ignition point and is safe. And it has a significant whitening effect on the surface of the workpiece.

It is extremely effective in removing flash, burrs, casting traces and other surface treatments of die castings. Hardness: HV80-100

Compared with ordinary steel shot, zinc shot and stainless steel shot, it has many advantages.

1. Strong deburring and flashing ability

2. Operation safety

3. Reduce the consumption of shot blasting machine parts, and the loss of props generated by subsequent mechanical processing is small

4. Reduce equipment maintenance costs

5. The surface of the workpiece is bright and the price is high

6. Because it is an alloy material, there is a risk of dust explosion

Application range:
Widely used for enhanced deburring of the surface of ferrous metal and non-ferrous metal parts, polishing of non-ferrous metal parts and main surface finishing of parts, as well as metal die-casting, precision casting, hardware tools, machinery manufacturing, auto parts, instrumentation, Surface treatment such as descaling, deburring, surface defect elimination, internal stress relief, etching, matte effect, smoothing, strengthening, anti-rust before spraying, etc. in pump and valve industries.

Specification:
0.2mm-3.0mm can be customized according to customer requirements

Uses:
Mainly used for deburring and cleaning of various aluminum alloy and zinc die-casting products.

Several advantages of zinc shot:
the quality of zinc shot is strictly implemented in Q/G ZKS01---2003, due to advanced equipment, technology, strict inspection and control, now pure zinc shot has been supplied to many foreign-funded enterprises in China for a long time, and exported in large quantities Japan, India, the European Union, the Middle East, and other regions have established good trade relations with foreign businessmen and enjoy a high reputation in the domestic and international markets.

Product Selection Criteria

1. Appropriate hardness

2 sufficient density

3 Appropriate metallographic structure

Product testing:
No other ingredients enter from the raw material (zinc ingot) to the finished product, and there is no contact with other metals. Use DF-100 direct reading spectrometer, plasma inductively coupled atomic emission spectrometry, and other high-end detection instruments. Before storage, each process is checked and inspected layer by layer, and no tiny details are missed, so that the performance of our products can be stabilized for a long time, and the content of each batch of pure zinc shot is more than 99.99%. The company's testing center has perfect quality testing methods. At present, there are quality testing equipment such as carbon and sulfur analyzers, arc combustion furnaces, elemental analyzers, metallographic microhardness testers, etc., which can test the composition, hardness, and service life of products to ensure The products meet the national standards or the requirements of the purchaser.
