The manufacturer of industrial grade sodium hexametaphosphate will tell you about the harm of scale to the boiler. If the boiler is not cleaned for a long time in use, a large number of scale will be generated, and the scale will also cause great corrosion to the boiler wall:

1. Because of the poor thermal conductivity of scale, the heat transfer from heating to working medium is hindered, the heat absorption of working medium is reduced, the temperature of boiler exhaust gas is increased, and the heat loss is increased.

2. Due to the poor thermal conductivity of the scale, the heat transfer from the heating surface to the working medium is hindered. It is because the working temperature of the heating surface rises, which will cause the superheater of the heating surface to burst or overheat.

3. Natural water is the aqueous solution of electrolyte, which is easy to produce electrochemical corrosion when contacting with metal. Therefore, boiler water needs to be softened by industrial grade sodium hexametaphosphate, which will reduce the formation of scale.

4. If the salt scale is deposited on the valve of steam, it may cause valve action failure and valve air leakage.

Industrial grade sodium hexametaphosphate can not only dissolve calcium carbonate, magnesium carbonate, calcium sulfate, calcium silicate, iron oxide and other scale components, but also has no corrosion to metals, and can complex calcium, magnesium and other metal ions in hard water to play a soft water role. The industrial grade sodium hexametaphosphate produced by Chongqing Chuandong Chemical Group Co., Ltd. is produced from genuine phosphoric acid with stable quality, fast flow rate and less consumption.
