This is a procedure through which the residueof rust and other contaminantsparticles from any target surface can be cleansed or removed by shooting abrasive materials rapidly under high pressure. Sandblasting is considered widely accepted efficient procedure of debarring rust and corrosion from an object. Better known for wiping out the target surfaces for better finishing outlook, it helps companies, control their expenditures by recycling the objects.
Commonly used objects made from Fiberglass material such as bath tubs,boats, turbines etc. when these are broken or get damaged from any part or surface are usually sand blasted by the companies so asto recycle the objects. As the name implies sand remains the most commonly utilized sandblasting abrasive material, other optional choices for the users couldbe glass beads, graphite, Rice husk, baking soda, thermoset plastic, walnut shells, grain hulls, water, steam, dry ice and steel grit etc.
Sand Blasting methods
Below are the details of few methods of sand blasting which are eco-friendly.
- Rice Husk sand blasting method
This is an environment friendly method of sand blasting and involves the usage of a natural organic abrasive, RiceHusk. Rice husk sandblasting comprises of rice husk, or the outermost layer of rice, tosand blast surfaces. The abrasive material is forcefully blasted to remove grease, grime and surface rust from fiberglass.
- Thermoset Plastic
Thermoset plastic is another option used to sandblast fiberglass. In this method of sand blasting, tiny beads of soft plastic — urea, melamine or acrylic — at high volume and low pressure blasted to get rid of the rough surfaceof particles, primer, paint and filler.
Thermoset plastic sandblasting is quite cheaper as compared to other methods of sandblasting and works faster too, however; has not yet reported to work well to remove rustparticles from fiberglass surfaces.
- Soda blasting
Sodium Bicarbonate or commonly known as baking soda is another choice of users aiming to sand blast the fiberglass.Application of Baking soda sand blasting results in an intense cleaning action since it is non-toxic and water-soluble compound.Dry or wet soda under pressure is blasted to remove surface residue when there is Soda Blasting.
- Corn Cob Grit
Another environment friendly sand blasting method is using Corn cob grit. It imposes no threats to environment or health and is a good renewableoption. Corn cob grit is effective in removing remains of dirt, grease, paint and rust from fiberglass surfaces and provides the users with a wide range of availability.
- Walnut Shells
Walnut shells are also good choice for sand blasting operation .These are nontoxic ,renewable , and good option for removing dirt or broken surfaces from fiberglass automotive parts, bath tubs ,turbines and boat surfaces.
Walnut shells are soft, abrasive sandblasting media that wipe out fiberglass surfaces without imposing any threat to surface. Walnut shells are utilized in the operations of fiberglass finishing, debarring and deflating and act as a recyclable and pro-environment al sand blasting method.
