Applying Scientific Understanding: Explaining the Chemistry Behind Adding Salt to Lime Wash
As humans, we are natural experimenters. When we come across a new phenomenon, it is in our nature to try and understand it by testing it out. One such example is adding salt to lime wash. It may seem like an odd combination at first, but as soon as you start applying scientific understanding, the chemistry behind this practice starts to make perfect sense.
Lime wash is essentially a mixture of lime powder and water. It has been used for centuries as a coating for walls, buildings, and even furniture. It’s durable and can last for years – sometimes even centuries! One issue with lime wash, however, is that it can dissolve when exposed to water or acidic substances like rainwater. This can lead to erosion and quick deterioration of any surface coated with lime wash.
However, when salt is added to the mix (usually about 1-5% of the total mixture), something amazing happens! The compound sodium chloride reacts with the calcium hydroxide in lime powder forming calcium chloride (#CaCl2) and sodium hydroxide (#NaOH). Sodium hydroxide plays the role of a coagulating agent in binding the mixture together taking deeper root within fibers while Calcium Chloride acts as an accelerator enhancing setting time of plaster.
The addition of salt thus leads to two key benefits:
Firstly: Lime wash will become more durable since the coagulating effect brought about by sodium hydroxide helps improve binding properties needed for hardness during curing while increasing resistance towards rainfall ensuring longevity.
Secondly: Adding salt reduces drying time by altering propertiesof Lime-wash.The calcium chloride molecule created after mixing react components also has phenomenal benefits viz-a-viz controlling permeability resulting from specific chemical reactions taking place upon application which will deter growth of microorganisms & fungi while keeping mold out giving extra life span & superior functionality regardless its environment which provides much need flexibility especially where constant change was required
Adding salt to lime wash may seem like an odd combination, but once you delve into the chemistry behind it all becomes clear. The addition of sodium chloride results in a chemical reaction that improves the coagulating properties of the mixture, reduces drying time and creates a more durable surface due to forming calcium chloride which accelerates setting time in cementitious products.
So next time you’re applying lime wash – be sure to add some salt!
Traditional vs Modern Approaches: Comparing Techniques for Adding Salt to Lime Wash
The techniques that are used to add salt to lime wash have been around for centuries and have proven successful.
