Description
Technical field
The present invention relates to a kind of scale remover, specifically a kind of Industrial Boiler scale remover.
Background technology
Most equipment after used a period of time, all can produce dirt more or less, and these dirts will affect the normal use of equipment, it is therefore desirable to dirt is cleared up by timing.Typically being bonded on equipment due to dirt, cleaning up is relatively difficult, especially some small-sized, special-shaped equipment.Scale remover is a kind of chemicals going multiple dirt stain such as scale removal, dirt, is typically formed by various ingredients is compounding.According to the difference of application, scale remover is roughly divided into industrial scale remover and household descaling agent, and industrial scale remover is mainly used in removing the dirt in heat transmission equipment, boiler etc., and household descaling agent is mainly used in removing the dirt in water dispenser, kettle etc..
Industrial Boiler generally refers to the boiler for the heating in industrial production, boiling, drying, factory building or the aspect such as people's heating for residential area and hot water supply.When in boiler, water temperature raises, the salt in water concentrates, and will produce deposition when its concentration exceedes the solubility at a temperature of this, and some salts, as calcium sulfate, magnesium sulfate, calcium phosphate etc. then decline as temperature rises high-dissolvability and separate out；In the boiler, also can separate out when basicity is come higher by the concentration of silica；And solubility heavy carbonate, as carbonic acid calcium dihydrogen, carbonic acid dihydro magnesium are then thermally decomposed, produce indissoluble salt and also result in deposition.These deposits are generally fixedly arranged at boiler or pipe surface, bring serious harm to normal use of boiler: first, and dirt thermal conductivity extreme difference can cause uneven situation of conducting heat because being heated, thus waste fuel or electric power；Secondly, if dirt is consolidated in boiler inner wall, also can greatly increase boiler and burst, owing to expanding with heat and contract with cold and unbalance stress, the danger even exploded；Again, during dirt consolidation, also usually can adhere to plurality of heavy metal ion, if this boiler is used for containing drinking water, have heavy metal ion and be too much dissolved in the risk of drinking water.It accordingly, it would be desirable to a kind of efficient boiler scale remover of research, is attached to the dirt of boiler inner wall with removing quick, thorough.
