FAQ's of Copper Slag LLP:

Q: How should Copper Slag LLP be stored for optimal preservation?

A: Copper Slag LLP should be stored in a dry condition to maintain its quality. Thanks to its insolubility in water and stability, it features an unlimited shelf life if properly protected from moisture.

Q: What is the main process for using Copper Slag LLP in abrasive blasting?

A: During abrasive blasting, Copper Slag LLP granules are propelled at high velocity onto a surface. This effectively removes rust, paint, and other contaminants, providing a clean profile for coatings or treatments.

Q: When is Copper Slag LLP most beneficial for industrial applications?

A: Copper Slag LLP is ideal for use when high efficiency and minimal health risks are critical, such as in shipyards, construction sites, and facilities preparing metal surfaces for painting or coating.

Q: Where can Copper Slag LLP be used in construction and surface treatment?

A: It can be applied to concrete and steel surfaces for cleaning, roughening, and preparing them for new coatings, as well as for non-slip flooring and shotcrete aggregate in the construction industry.

Q: What are the advantages of selecting Copper Slag LLP over other abrasives?

A: Copper Slag LLP offers high purity (96-99%), low free silica content, and non-toxic properties. These attributes ensure superior safety for workers and compliance with environmental standards, while also delivering reliable abrasive performance.

Q: How does the packing and size range benefit different industries?

A: Copper Slag LLP is available in 25 kg, 50 kg bags or bulk packaging, and its granule sizes from 0.2 mm to 3.0 mm allow customization for specific industry needs and equipment compatibility.
