Descaling anticrustator and use method thereof

Abstract

The invention discloses a descaling anticrustator, which is prepared from the following components according to parts by weight: 50-70 parts of sodium carbonate, 20-25 parts of sodium pyrophosphate, 45-60 parts of tanning extracts, 15-30 parts of sodium sulfate, 8-16 parts of trisodium phosphate, 3-8 parts of sodium gluconate and 7-12 parts of starch. The descaling anticrustator has the beneficial effects that a descaling and antiscaling effect is improved, secondary scaling is avoided, and the descaling anticrustator has the advantages of environment protection, no toxicity, no taste, efficiency and energy saving.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a descaling and antiscaling agent and a using method thereof. Background technique [0002] As a traditional winter heating equipment, boilers are very common in our country. The existing boiler feed water treatment is unqualified, which will cause great corrosion to the boiler, and will cause hard scale to form on the heating surface of the inner wall of the boiler. [0003] The boiler and other heating equipment generate scale because the boiler feed water contains a certain amount of calcium, magnesium ions and other heavy metal ions. During operation, the calcium and magnesium ions absorb heat and chemically react with carbon dioxide dissolved in the water to form insoluble substances. . And the water is heated in the furnace to generate water vapor, the concentration of calcium and magnesium carbonate in the furnace water is getting higher and higher, and the solubility of...

Problems solved by technology

However, when the above-mentioned alkaline is used for descaling, it takes a long time and the effect is not ideal

Regardless of pickling or alkali washing, the scale detaches into flakes, which is a serious phenomenon of pipe blockage. The existing descaling method also has the method of acid washing and then alkali washing, but this method not only causes serious corrosion to steel damage and damage the service life of the equipment, and the traditional alkali antiscaling agent still has the problem of secondary scaling during use (the calcium and magnesium plasma dissolved in the circulating water will be lost in the boiler and pipeline with the loss of temperature, time and steam. Hard-to-dissolve scales form on the surface)

[0006] During the heating period, because the circulating water in the radiator is relatively clean, there is a phenomenon that residential users release the hot water in the heating for other purposes, and when the boiler and piping system lose water, the cold water is replenished, and the cold water must be replaced by fuel. Running hot, a lot of fuel will be wasted in winter
