Garnet is a mineral extensively used for sandblasting, and is frequently stemmed from deposits of either Almandite or Andradite. There are many advantages to using Garnet minerals over other minerals, as it can be utilized for both damp and dry sandblasting applications. As a commercial gems, garnets create a profile that is practically without embedment. Due to this factor it is utilized for finishing adhesion, and is likewise excellent for applications where it is required that there is low or no transfer of grit into the substrate.
Garnet is chosen as a sandblasting mineral in tanks and other restricted spaces where usage of a low cleaning abrasive is required; and in dry docks, bridges, and shipyards where water contamination is an issue. It is likewise commonly utilized in Aluminium and Fiberglass surface areas, Hangar decks and Industrial Painting. Garnet is utilized in powder covering and in denim blasting too. It is available in tones of colours varying from Pink, Red to Brown, and Grey to Brown; and in densities ranging from 135 lbs/ft3 to 150 lbs/ft3.
Advantages of utilizing garnet applications
Low Cleaning emissions
Garnet is proven to be a fast and tidy blast media. Blast cleaning using Garnet is cleaner, as it provides significantly lower dust emissions due to its fundamental material strength. The material has high specific gravity and allows for quick settling. This is useful as it causes minimum disturbance to nearby operations, and allows for clear operator exposure.
When there are a larger number of grains of a specific shape influencing on the surface at a high speed, it is possible to accomplish extremely quickly cutting. Smaller grains of garnet speed up a lot more quickly and use greater effect energy to surface areas. This leads to an exceptional cleaning rate – which is usually twice the rate achieved when using traditional abrasives.
Lower consumption of the mineral- possibility of recycling
Garnet is a really expense reliable abrasive as it will last a lot longer due to its solidity. (Mohs Firmness is 7 to 8 depending on the type of garnet used). When garnet is used, there are lots of more active grains affecting the surface area which greatly decreases abrasive consumption. This likewise means that you can recycle a number of times, generally at least two times, and in some cases more when beginning with a coarser grade.
Garnet is found to be non-toxic with very low totally free silica levels (usually less than 1%). This guarantees that there is no threat of silicosis, or any risk of contamination from leachable heavy metals or radioactive compounds. Due to lower intake and recyclability, disposal volumes are significantly decreased. This makes using garnet ecologically much safer and more sustainable. As a result, garnet is often utilized to blast structures that are nearby bodies of water, so that there is no contamination by the blasting media itself.
Exceptional for finishing preparation usage – produces Superior Surface area Quality
Garnet grains are able to tidy deep into the cavities and pitted areas right down to the bare metal, which leads to a blasted surface that is free of embedment and rogue peaks and troughs.
All rust, soluble salts and other contamination’s are completely removed.
Garnet sizing and profiles:
16 – Really Coarse, utilized for blast spaces on blasting steel, bridges, ships and tanks
36 – Coarse, used for thick coverings, marine fouling, and rust
30 ×40 – Intermediate, utilized on much heavier finishings and rust
30 ×60 – Medium, used for brand-new steel and maintenance for coverings
80 Mesh – Medium Fine, utilized for aluminium and other sensitive substrates, including marine aluminium applications, and hydro blast cleansing operations
100 Mesh – Fine, can be used on aluminium and fiberglass, in addition to for rust elimination and mill scale on brand-new steel, also a perfect water jet cutting abrasive
