Scope of application:
     It is used for steam boilers, hot water boilers, steam locomotive boilers below 2.45MPa, for cleaning various scales for various heaters, coolers, evaporators, condensers, compressors, water cooling and water heating jackets and piping systems.
1. It is more effective than pickling and descaling: it has excellent cleaning effect on various types of insoluble scales which cannot be removed by pickling. Even the most stubborn sulfate scale can be completely removed.
2. Safer than pickling and descaling: cleaning under neutral or alkaline conditions (pH 7~12), no corrosion damage to metal; long-term use has no adverse effect on mechanical equipment performance and service life.
3. Compared with pickling and descaling economy: cleaning in the normal operation of the equipment, the cost is lower than the regular pickling cost; does not affect the production, no loss of production.
4. It is simpler than pickling and descaling: this product can be added in proportion to water, scale removal, scale and scale prevention. Anyone can operate.
5. Non-toxic, harmless and non-polluting: This product does not affect steam quality when the boiler is in normal operation, and can be used for operation cleaning of steam boilers and other equipment in food and sanitary industries. The cleaning waste liquid has no pollution to the environment.
Physical and chemical properties:
Appearance: brown liquid                  water soluble: easy to dissolve
Density (20 °C), g/cm3: 1.15 ~ 1.18          flammability: non-combustible
1. Boiler:
① Keep the pH value of the pot water at 10~12. If the pH value is lower than 10, adjust to 10 or more with mixed sodium hydroxide (1 part sodium hydroxide plus 2 parts sodium carbonate).
② The steam boiler discharges once per shift, and the sewage discharge rate is 8-10% (the boiler with large evaporation capacity increases the number of blowdowns)
③ When the scale is less than 3mm and the boiler is running at full load for 24 hours, the descaling period is generally 30 to 40 days. When the fouling is thicker or lower, the descaling cycle needs to be extended. Sulfate and silicate scale descaling cycle.
④Each sewage valve should be arranged when draining, and no blind spots should be left to deposit with scale particles.
2. Anti-scaling of other heat exchange equipment:
  According to the total water volume of the system, the amount of water per ton is increased by 4 to 7 kg in advance, and it is added to the cooling pool or the water tank to inject the system into normal operation; it can also be directly injected into the system. Later, according to the proportion of hydration, the anti-scaling dosage is 20g/ton of water, and the sewage is discharged once every 10~15 days.
1. In addition to the anti-scaling period, the product should be used continuously, it should not be interrupted, otherwise it will lose the scale and anti-scaling effect and increase the dosage.
2. In addition to, anti-scaling, timely discharge of sewage, so as to avoid the deposition of dissolved scale particles blocking the pipeline, the lack of sewage will reduce efficiency.
Packaging and storage:
1.5000g/barrel, 4 barrels/carton. Plastic drum carton packaging.
2. Store in a cool dry place, sealed and stored for 2 years.
