Description
Technical field
The present invention relates to a kind of scale remover, particularly a kind of removing incrustation scale reagent and using method thereof.
Background technology
Incrustation scale is a common objectionable impurities in production and the life, its main component is throw outs such as lime carbonate and magnesium hydroxide, the density of incrustation scale and thickness all can be because of the time of using and purposes and different, these incrustation scale clear water can't clean up, and present on the market the certain shortcoming of scale remover ubiquity on descale effect, even also have a lot of scale remover itself just to possess stronger corrodibility, also be worthless to being damaged very big like this by the life-span of scale removal utensil, especially industrial boiler, of many uses, the cost height when will guarantee features high scale-removing effect, also requires safe and reliable.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of removing incrustation scale reagent, the present invention also provides the using method of above-mentioned removing incrustation scale reagent, the present invention includes following materials of weight proportions composition: citric acid 2.0 ~ 6.5%, sodium bicarbonate 3.0 ~ 13.0%, thionamic acid 12.0 ~ 18.0%, hexamethylenetetramine 1.2 ~ 2.5%, remaining is a water; Wherein, at normal temperatures, as long as keeping dry, thionamic acid do not contact with water, the solid thionamic acid is non-hygroscopic, more stable, and the aqueous solution of thionamic acid has and hydrochloric acid, the strongly-acid that sulfuric acid etc. are equal, so another name is solid sulphuric acid again, it has non-volatile, no stink and the characteristics minimum to human toxicity, the thionamic acid aqueous solution is slower to the corrosion product effect of iron, can add a certain amount of citric acid, sodium bicarbonate and hexamethylenetetramine, thereby dissolved iron dirt effectively, the aqueous solution of above-mentioned removing incrustation scale reagent can be removed iron, steel, copper, the incrustation scale and the corrosion product of the equipment surface that materials such as stainless steel are made, in addition, thionamic acid still is unique acid that galvanized metal surfaces cleans that can be used as.
In the used raw material, hexamethylenetetramine is a kind of inhibiter commonly used, also is solubility promoter, is used to slow down Corrosion of Metallic Materials, is widely used in iron and steel, casting, prepare composite; Above-mentioned removing incrustation scale reagent descale effect is fine, does not produce deleterious material, can also can not injure HUMAN HEALTH to by the corrosion of damaging property of scale removal utensil, and is safe and practical.
In order further to realize removing incrustation scale reagent, comprise following materials of weight proportions composition: citric acid 3.0 ~ 5.5%, sodium bicarbonate 5.0 ~ 12.0%, thionamic acid 15.0 ~ 17.0%, hexamethylenetetramine 1.5 ~ 2.0%, remaining is a water, and this ratio can be removed the incrustation scale that produces in various lives and the production more apace.
To remove incrustation scale reagent in order further realizing, to comprise following materials of weight proportions composition: citric acid 4.5%, sodium bicarbonate 11.0%, thionamic acid 16.5%, hexamethylenetetramine 1.7%, remaining is a water, this ratio can fast and effeciently be removed the incrustation scale that produces in various lives and the production.
To remove incrustation scale reagent in order further realizing, to comprise following materials of weight proportions composition: citric acid 5.0%, sodium bicarbonate 11.5%, thionamic acid 16.8%, hexamethylenetetramine 1.5%, remaining is a water, this ratio can efficiently be removed the incrustation scale that produces in various lives and the production.
The present invention also provides the using method of described removing incrustation scale reagent, and as dirt thickness≤2.0mm, the weight that adds above-mentioned removing incrustation scale reagent is by 3.7 ~ 5.0% of the volumetric water weight of scale removal utensil; On this basis, the every increase of dirt thickness 0.5mm, the add-on of removing incrustation scale reagent increases by 1.0 ~ 2.1%.
Particularly, add according to the above ratio and remove after the incrustation scale reagent, stir and dip operation, described stirring velocity is 30r/min, and described soak time surpasses 200min; In the process of soaking, keeps specific stirring velocity can improve the efficient of scale removal, this rotating speed of 30r/min both can be fine scale removal, also can be to by the excessive pressure of scale removal utensil inwall generation; As the thickness of incrustation scale or density thickening, the rotating speed that can also stir according to the practical situation appropriate change and the time of immersion, again or increase the amount of removing incrustation scale reagent.
The invention provides the using method of described removing incrustation scale reagent, dirt thickness≤2.0mm, the weight that adds above-mentioned removing incrustation scale reagent is by 4.8% of the volumetric water weight of scale removal utensil; On this basis, the every increase of dirt thickness 0.5mm, the add-on of removing incrustation scale reagent increases by 1.8%.
Particularly, add according to the above ratio and remove after the incrustation scale reagent, stir and dip operation, described stirring velocity is 30r/min, and described soak time surpasses 200min; In the process of soaking, keeps specific stirring velocity can improve the efficient of scale removal, this rotating speed of 30r/min both can be fine scale removal, also can be to by the excessive pressure of scale removal utensil inwall generation; As the thickness of incrustation scale or density thickening, the rotating speed that can also stir according to the practical situation appropriate change and the time of immersion, again or increase the amount of removing incrustation scale reagent, even can increase operation such as the pressurization of heating, just can reach better descale effect like this.
The invention provides a kind of removing incrustation scale reagent and using method thereof, remove incrustation scale reagent and comprise following materials of weight proportions composition: citric acid 2.0 ~ 6.5%, sodium bicarbonate 3.0 ~ 13.0%, thionamic acid 12.0 ~ 18.0%, hexamethylenetetramine 1.2 ~ 2.5%, remaining is a water; The present invention can change its using method according to by the amount of capacity of scale removal utensil and incrustation scale thickness, and features high scale-removing effect can not produce objectionable impurities, can be to by the corrosion of damaging property of scale removal utensil, and safe and practical.
