Four quadrants at the base of the Grit Guard Insert calm the wash water and hold the grid above the bottom of the bucket.Dirt falls to the bottom and stays there.
下面四条辐条起了阻隔作用可以让水流相对静止下来。
The Grit Guard Insert is a real paint-saver. But it has a number of other uses, too. Use it to clean paint brushes by running the bristles across the grid in a bucket of water or paint thinner. Clean automotive parts or drain your oil filter. You can even use the four quadrants as a grid when laying tile.
另外用法,把刷子也好棉垫也好在它上面刷,让污迹落下进网里去。
The Grit Guard is American-made and patent-pending.
它其实不贵,因为在老美处制造,卖9.99刀,这里面人工铺租利润之类占了大头。到这里卖多少钱是另外一回事,记得油坛前几天有个帖子,老干妈在美亚卖到十几美刀一瓶,道理相同。
Two Grit Guard Inserts are better than one! For optimum paint protection, stack two Grit Guards in one bucket.
把两个叠起来放在一个桶里,保护性更好。
===========================
很明显,只要下层水流相对静止,那么泥沙就不会跑到上层去,那么我们可以改变一下清洗的手法,就如海洋,上面波涛汹涌,海底还是相对平静,因为只是上层水流在动,我们在水面漂洗应该就不会引起桶底的水出现旋流了,虽然不如滤网,但是也能达到一部分效果。
