Witryna1. Calcium build-up on the pool surface. High pH levels will cause calcium carbonate in the water to precipitate or bond to the fibreglass surface. When this happens, it often leaves a white gritty layer that looks much worse when dry. As the picture shows, this white layer becomes very noticeable when the pool water drops below its normal level. WitrynaWhen the film thickness is the result of a balance between these factors, it is called hydrodynamic lubrication. In applications with rolling contact (and thus negligible relative sliding motion), film thickness between the metal surfaces can still occur, even with greater localized pressure points.
