Its anticorrosion-antiscaling effect.
The corrosion inhibition rate of the measure of the results show present invention is 99.6%, scale inhibition performance 99.8%.
From specific embodiment one to embodiment ten, the recirculated cooling water corrosion inhibiting and descaling agent can be applied to highly concentrated demagnification
(such as make the benefit of cooling circulating water with high-salt wastewater or other intractable industrial wastewaters in number (more than 10 times), perishable water quality
Water-filling), it can almost reach the effect of not burn into non-scaling, it is industrial particularly when chlorine ion concentration is up to 10~150,000 mg/L
Circulation (carbon steel, stainless steel and copper material) can also reach anticorrosion, good antiscale property, thus both saved supplement water and
The burden of factory's water process is alleviated, and realizes the effect of waste water low-discharging.
The corrosion inhibiting and descaling agent of the present invention has that raw material sources are extensive, production cost is low and in use relatively low dense
Degree is lower to can reach excellent anticorrosion-antiscaling effect, further saves processing cost.
3) corrosion inhibiting and descaling agent of the invention is applied to industrial circulating cooling water system, can extend service life, ensures enterprise
Industry production is smoothed out, and substantially reduce enterprise uses water cost.The heat transfer coefficient of equipment is improved at the same time, reduces equipment energy
Consumption.
Basic principle, main feature and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, various changes and modifications of the present invention are possible without departing from the spirit and scope of the present invention, these change and
Improvement is both fallen within the range of claimed invention.The protection domain of application claims by appended claims and its
Equivalent defines.
