Need an excuse to indulge in a lobster dinner tonight? In the United States, June 15 is National Lobster Day, a time for savoring and paying tribute to one of Americaâs most beloved crustaceans. In honor of the holiday, check out these shell-shocking facts about lobster and its long, meaty history. â¢ When the first European settlers reached North America, lobsters were so plentiful that they would reportedly wash ashore in piles up to 2 feet high.
An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away. coated abrasive comprises an abrasive fixed to a backing material such as paper, cloth, rubber, resin, polyester or even metal, many of which are flexible. Sandpaper is a very common coated abrasive.
Just as there are many surfaces to be cleaned there are many different types of abrasive materials that can be used. Although there are many reasons, we believe there are three important reasons why we do not recommend the use of sand. The first reason is a health and safety concern. Sand contains silica which can cause serious respiratory illnesses. The use of a proper respirator with most abrasives will reduce your health risks. The second reason is due to the high moisture content and the impurities in sand. It can cause equipment blockages and other moisture related problems that can cause premature failure of your blast equipment. The third reason is sand just does not work as well as other abrasives. Sand used once in a blaster turns into a powder and loses its abrasive capabilities. Using the correct abrasive can make the job go quicker and using the right abrasive can give you a more desirable finish to the item you are blasting.
