Problems solved by technology

And the scale is easy to cause fuel waste, easy to cause accidents, and affect safe use
Regular cleaning of equipment dirt can save fuel, reduce overall equipment maintenance costs, and extend the service life of equipment. At present, most boilers are cleaned by pickling or alkali soaking, and then rinsed in clean water. The operation is cumbersome and acid and alkali will cause corrosion to the boiler. , shorten the service life
[0003] At present, there is a lack of a descaling agent that is non-toxic, harmless, and non-corrosive to equipment

Embodiment 1

[0022] The invention provides a kind of descaling agent, and described descaling agent is made up of following components by mass percentage:

[0023]

[0024] The metal corrosion inhibitor is a combination of four kinds of glucose, starch, pectin and sodium gluconate. The auxiliary material is food-grade essence. The antirust agent is a combination of triethanolamine and sodium nitrite.

[0025] A kind of preparation method of described descaling agent of the present invention, in step (1), with solid material citric acid, sulfamic acid, fumaric acid, maleic acid, sodium dodecylbenzene sulfonate Sequentially add to the chemical reactor, then add water and stir evenly to dissolve the solid material; the stirring speed during stirring is 500r / min.

[0026] In step (2), the liquid materials acetic acid, hydrochloric acid, lactic acid and corrosion inhibitor are added into the chemical reactor and stirred evenly to make them fully dissolved; the stirring speed during stirrin...

Embodiment 2

[0033] The difference between embodiment 2 and embodiment 1 is: the present invention provides a kind of descaling agent, and described descaling agent is made up of following components by mass percentage:

[0034]

[0035]

[0036] The metal corrosion inhibitor is a combination of glucose, starch and vitamin C. The auxiliary material is a combination of food-grade essence or food-grade colorant. The rust inhibitor is sodium nitrite.

Abstract

The invention discloses a descaling agent. The descaling agent is prepared from the following components in percentage by mass: 1%-5% of acetic acid, 0.5%-6% of citric acid, 0.1%-0.6% of fumaric acid, 5%-10%o of sulfamic acid, 5%-40% of hydrochloric acid, 2%-10% of lactic acid, 1%-20% of maleic acid, 1%-3% of sodium dodecyl benzene sulfonate, 1%-3% of metal corrosion inhibitor, 5%-8% of corrosion inhibitor, 2%-4% of auxiliary materials and the balance of water. The descaling agent is non-poisonous and harmless to human bodies, capable of rapidly dissolving water scale, safe and reliable, has low corrosion to devices and mild performances, can save energy sources, does not hurt the skin and does not influence human health.

Description

technical field [0001] The invention relates to the field of chemical reagents, in particular to a scale remover. Background technique [0002] After long-term heating of water equipment, scale and corrosion problems inevitably appear. The main reason for the formation of scale in the boiler is that the feed water contains hardness components. After continuous evaporation and concentration at high temperature and high pressure, a series of physical, A chemical reaction eventually forms hard, dense scale on the heating surface. Scale affects human health, easily causes gastrointestinal digestive and absorption disorders and constipation, and increases the incidence of gastritis and various stones. And the scale is easy to cause waste of fuel, easy to cause accidents, and affect safe use. Regular cleaning of equipment dirt can save fuel, reduce overall equipment maintenance costs, and extend the service life of equipment. At present, most boilers are cleaned by pickling or a...
