Abstract
Scale removal, scale inhibitor prescription and production method relate to a kind of formula of medicine and production method that is used for metallic surface scale removal, antiscale, it is characterized in that its compatibe drug is mixed with a kind of scale descaling agent that can remove heterogeneity, can prevents the scale inhibitor that various incrustation scales generate with special methods, realize the long-term safety operation of boiler purpose, be applicable to factory, mine, office and boiler applying unit.
Description
The present invention relates to incrustation scale on a kind of water quality wall of container and remove and prevent chemical agent prescription and the production method that incrustation scale generates.
In human daily life and production practice activity, water is indispensable, human when utilizing water, often want heated and boiled, transform other forms.Because the composition difference of water often makes the different incrustation scale of a kind of composition of formation on the wall of container of heating, converting apparatus.The incrustation scale thermal resistance is strong, high consumption fuel, and incrustation is many more, and container volume is more little, causes some equipment scrapping.Therefore the mankind have accumulated scale removal knowledge gradually in long-term production and practice, inquire into the scale removal way.At present, the maximum scale remover of domestic application is the mixture of tertiary sodium phosphate, yellow soda ash, sodium hydroxide, tannin extract powder and part saltcake.Place it in long-time heating in the container during use, short dirt comes off.Though this medicine has the detergency function, long because of the time, how unsatisfactoryly expend, hope dirt heave a sigh especially after meeting siliceous incrustation scale.In addition, said medicine can only but actively antiscale of passive scale removal, and therefore, its promotion and application all are restricted.
The present invention's purpose be to society provide a kind of scale removal speed fast, can remove scale removal, scale inhibitor combination formula that multiple dirty matter incrustation scale comes off and anti-scaling function is arranged.
In order to finish above-mentioned task, the present invention has adopted following scheme when design: (1) increases oxygenant-hydrogen peroxide, lubricant Sodium salts humic acids in prescription, and the poly-Sodium Propionate of stablizer is aided with other components and facilitates descale effect, stablizes the antiscale function.(2) change blending process, increase material contact area, accelerated reaction process.(3) this medicine stresses antiscale, and scale removal just wherein one encircles, the scale removal of two different ingredients, scale remover, and coming down to the antiscale is that purpose, scale removal are means, the comprehensive regulation.
Contain the present invention of above-mentioned design philosophy, it is fast, effective that its product is removed the metallic surface speed of water scale, and the human-saving material resources can be removed various composition incrustation scales, particularly siliceous incrustation scale.Can replace soft water system, laborsaving saving time during antiscale.
Implementation method of the present invention is:
To add tertiary sodium phosphate, Sodium salts humic acids successively behind yellow soda ash, the saltcake thorough mixing, make the mixture that once lumps, and it is crushed to more than 80 orders, again its powder and liquid caustic soda are stirred, and when stirring, add hydrogen peroxide, make the secondary block mixture, after sub-sieve is pulverized secondary block mixture to 80 order, again polyacrylic acid is sealed 5-8 hour with the pulverizing material mixing composting of secondary block mixture, above-mentioned compound and valonex powder are all mixed made scale remover at last.
The various one-tenth of scale remover are grouped into weight ratio and are: yellow soda ash 10-12%, liquid caustic soda 10-14%, tertiary sodium phosphate 10-14%, Sodium salts humic acids 1-7%, hydrogen peroxide 1-8%, polyacrylic acid 1-6%, sodium octyl 1-8%, valonex 16-4%, saltcake 50-26%.The consumption of scale remover is that the per ton of boiler consumption is 100kg, injects to boil about flushing, time 1-3 days and get final product Ex-all.
The production method of scale inhibitor is:
With saltcake, tertiary sodium phosphate, Sodium salts humic acids, sodium octyl, polyacrylic acid, hydrogen peroxide, alum, liquid hydrogen sodium oxide mix successively stir behind the block mixture, crushing screening 80 orders heap envelope after 5-8 hour scale inhibitor.
The various medicine proportion of composing of scale inhibitor are:
Tertiary sodium phosphate 8-12%, sodium hydroxide 8-12%, Sodium salts humic acids 3-8%, hydrogen peroxide 3-8%, polyacrylic acid 4-9%, sodium octyl 6-12%, alum 4-8%, saltcake 64-31%.
The usage quantity of scale inhibitor is about 10 of a boiler water loss, every month 1-3 time.
Implementing method of the present invention is: by formula rate quantitative hexamethylenetetramine is added in the gauge water after the stirring and dissolving at normal temperatures, add the quantitative Sodium Thiocyanate 99 of compatibility in turn, if add quantitatively acid again after the fourth, urotropine, aniline stirring and dissolving.
Formulation Example of the present invention has two:
(1) pure water 1976 grams, hexamethylenetetramine 74.1 grams, Sodium Thiocyanate 99 86.45 grams, if fourth 61.75 restrains, urotropine 49.4 grams, aniline 98.8 grams, industrial acids (hydrochloric acid, sulfuric acid or other acid) 10003.5 grams.
(2) pure water 1976 grams, hexamethylenetetramine 481.65 grams, Sodium Thiocyanate 99 481.65 grams, if fourth 456.95 grams, urotropine 456.95 grams, aniline 494 grams, industrial acids (hydrochloric acid, sulfuric acid or other acid) 8002.8 grams.
The proportion compatibility of various medicines is: water 16%, hexamethylenetetramine 0.6-3.9%, Sodium Thiocyanate 99 0.7-3.9%, if fourth 0.5-3.7%, urotropine 0.4-3.7%, aniline 0.4-4%, sour 81-64.8%.
The cleaning agent for quick descaling at normal atmospheric temp that aforesaid method and prescription are produced only need inject in condenser, compressor sleeve pipe, the generating tube soaking flushing recycle repeatedly can Ex-all incrustation, inject boiler and heat and get final product clean the boiler.
