Hot water is bottled water why there's always a silver deposits?
For a family, it's not that serious waste. For the factory, the problem will be big. Factory heating steam supply with large boiler, some to send several tons per hour steam, dry up equivalent to several tons of water. According to the test, a ton of the river is about 1.6 kg in minerals; And a ton of the minerals in the well water up to 30 kilograms. One day delivery dozens of tons of steam, hard water scale, in the face of the boilers sedimentary and how amazing! Knot in the large boiler scale, such as the boiler wall plate build up between the water and a heat insulation wall. Boiler plate touching water, with burning furnace fire 1 vigorously the steel plate. If scale cracks and leakage of water immediately to the high temperature of steel plate, rapid evaporation, causing pressure in the boiler, will be an explosion. As the power of the boiler exploded a bomb! The dangers of visible scale, must not be taken for granted! In factories, therefore, often in the water to join the right amount of sodium carbonate (the common name for soda), make the calcium and magnesium salts in the water precipitation, water becomes a soft water. Make hard water by ion exchange resin, also can remove the minerals, water softener [1]. Water bottle, thermos bottle steadily scale in the home, how to clean? Scale mainly of calcium carbonate, magnesium hydroxide, they can and acid chemical changes. According to this reason, pour some food in the canteen citric acid or citric acid detergent market (cooking vinegar can also), on the fire warm, see a scale on the release of the tiny bubbles and scale quickly dissolved. In a thermos flask scale so removed, no problem.
That's scale scale is because KaiShuiHu with for a long time, the lining will grow a thick layer of impurities. With calcium (Ca), magnesium (Mg) salts such as mineral water is called "hard water". River water, lake water, well water and spring water is hard water. Tap water is the river, lake, or well water sedimentation, remove the sediment, after disinfection sterilization, also hard water. Just under the rain and snow, the water does not contain minerals, is "soft water. Part of water to boil, after water evaporated, originally bad dissolved calcium sulphate (CaSO4, gypsum is the containing water of crystallization of calcium sulfate) settle. Originally dissolved calcium bicarbonate (Ca (HCO3) 2) and magnesium bicarbonate (Mg (HCO3) 2), decomposition in the boiling water, release carbon dioxide (CO2), become difficult to dissolve calcium carbonate (CaCO3) and magnesium hydroxide (Mg (OH) 2) also settle, sometimes generate MgCO3. Thus formed the scale. With hard water to wash clothes, the calcium and magnesium ions in the water and soap, generation of fatty acid calcium and magnesium of fatty acids floc, this is the origin of "tofu". In hard water wash his clothes, and waste of soap. The kettle steadily scale, is not easy to heat transfer, waste of fuel.
The water scale, rust and other deposits and suspended solids.
Silver deposits is scale, if there is excessive scale, shows that the quality of your home is hard, water to drink less as far as possible, it is certainly safe to drink boiled water.
