Traditional dry abrasive blasting and water blasting are used widely throughout the heavy industries for rust and corrosion removal, industrial coating and tank lining removal and paint layer removal, but these processes have some not so pleasant ramifications.
While traditional dry blasting methods create significant amount of dust, water blasting generates large amounts of slurry and chemical waste that must be contained – both of which can present damaging, dangerous and often costly ramifications for workers, quality control and the environment.
To add salt to the wound, these effects are stringently regulated – potentially causing compliance issues for companies who can face fines for using blasting techniques and equipment that may be non-compliant with Exposure Standards outlined in Safe Work Australia’s Abrasive Blasting Code of Practice.
Health issues – Airborne concentrations of certain substances can cause adverse health effects and undue discomfort to workers. Therefore, businesses must ensure that its workers aren’t exposed to levels that exceed relevant exposure standards.
Environmental challenges – Abrasive blasting produces shattered abrasive and dust combined with particles of the material being moved. According to the Abrasive Blasting Code of Practice, the waste material resulting from abrasive dry blasting must be collected, cleaned, reused or disposed of in accordance with local laws. Meeting these regulations however means incorporating costly catchment systems.
Therefore as traditional abrasive blasting methods are no longer acceptable, an industry-wide need for ‘dust-free’ blasting now exists. As a result, businesses must seek out ways to ensure they are deploying abrasive blasting solutions that are beneficial environmentally, financially and safety wise.
In order to conquer the great mess of slurry, chemical waste and dust produced in traditional blasting methods, a new abrasive blasting technology has emerged that also offers better control of pressure and the amount of media used – vapour abrasive blasting.
A cleaner, easier path to profitable results
Less water – Vapour abrasive blasting uses hardly any water because it uses vapour as a carrier for the blasting media.
Less media & dust – Vapour abrasive blasting uses less media and generates much less dust compared to dry blasting, since the vapour contains the dust immediately.
Less slurry – As a result of using much less water than water blasting, it produces hardly any slurry.
Less health risk – Seeing as less dust and slurry is created, vapour abrasive blasting poses less risk to worker’s health and safety.
Graco’s EcoQuip Vapor Abrasive technology gives users an equally powerful blast that works quickly like dry blasting, but requires a fraction of the media and the time required to clean it up. Using technology that optimises the air, water and media radio, businesses are left with savings in material, labour and disposal costs, which can turn into profits.
