Abstract
The invention discloses a preparation method of a cooler pipe detergent, relating to the technical field of cooler cleaning. The method comprises the following steps: A. heating 100-120 parts of water to 80 DEG C; B. adding 50-60 parts of sulfamic acid into the hot water in the step A, and dissolving; C. adding 2-28 parts of hydroxyacetic acid, 5-15 parts of tartaric acid and 0.2-2 parts of corrosion inhibitor into the solution in the step B, and stirring for 10-20 minutes; and D. slowly adding 2-5 parts of isomerized alcohol ether into the solution in the step C, and stirring for 10 minutes. The detergent prepared by the method can effectively dissolve and strip scales and rust in the cooler line, has ideal descaling effect, and has lower corrosivity for the cooler line.
Description
Technical field
The present invention relates to water cooler cleaning technique field, especially a kind of preparation method of water cooler pipeline clean-out system.
Background technology
Water cooler is a kind of heat exchanging apparatus, it uses water coolant as the heat-eliminating medium taking away equipment heat usually, because containing calcium, magnesium ion in water coolant, so water cooler internal duct is easy to produce incrustation scale, in addition, the oxygen be dissolved in water coolant also can cause metallic corrosion, form iron rust, these incrustation scales and iron rust are attached to the pipeline inner wall of water cooler, and cause heat transfer effect to decline, and thus need routine cleaning water cooler pipeline.Conventional purging method is scraped, the mechanical cleaning method of brush, high pressure water flushing washing method and chemical immersion purging method, the easy scratch pipeline of mechanical cleaning method, high pressure water flushing washing method is difficult to thoroughly remove the settlings such as incrustation scale, and the cleaning performance of chemical immersion purging method is best, but now commercially contain acid stronger mineral acid for the clean-out system of water cooler pipeline, because needs soak the long period, this clean-out system easily can cause corrosion to equipment, and copper water cooler pipeline internal memory is when greasy dirt, be difficult to effectively to remove the incrustation scale and rust that are covered by greasy dirt, cause descale effect undesirable.
Summary of the invention
The object of this invention is to provide a kind of preparation method preparing corrodibility pin and the desirable water cooler pipeline clean-out system of descale effect.
In order to solve the problem, the technical solution used in the present invention is: the preparation method of this water cooler pipeline clean-out system comprises the following steps:
A, 100 ~ 120 parts of water are heated to 80 DEG C;
B, 50 ~ 60 parts of thionamic acids are joined in the hot water of steps A and dissolves;
C, in the solution of step B, add 2 ~ 28 parts of oxyacetic acids, 5 ~ 15 parts of tartrate and 0.2 ~ 2 part of inhibiter stir 10 ~ 20 minutes;
D, in the solution of step C, slowly add 2 ~ 5 parts of isomery alcohol ethers, stir 10 minutes.
In the technical scheme of the preparation method of above-mentioned water cooler pipeline clean-out system, technical scheme can also be more specifically: also add 12.5 ~ 15 parts of sodium-chlor in step B.
Further, the stirring velocity of step B is 150 revs/min, and the stirring velocity of step D is 200 revs/min.
Further, thionamic acid 54 parts, oxyacetic acid 15 parts, 8 parts, tartrate, inhibiter 1 part, isomery alcohol ether 3 parts, 108 parts, water, 13.5 parts, sodium-chlor.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: the incrustation scale that the clean-out system preparing gained by present method can effectively dissolve and peel off in water cooler pipeline and rust, descale effect is desirable, and can reduce the corrodibility of clean-out system to water cooler pipeline.
