Abstract
The black corrosion inhibiting and scale retarding agent is prepared by mixing sodium humate and water soluble sulfide in certain proportion, and into the mixture, sodium methylene bis-naphthalene sulfonate, sodium salt and ash preventer. The scale retarding and water dyeing capacity of the sodium humate and water soluble sulfide are utilized. The product has high water solubility, fast diffusion, no toxicity, no smell, no toxicity, low cost and simple use, and has also effect of preventing heating pipeline from scaling.
Description
Technical field:
The present invention relates to a kind of civil heat supply system Scale inhibitors, say it is to disclose a kind of black corrosion inhibiting scale retarding agent definitely, belong to the chemicals technical field that the boiler pipe system prevents fouling.
Background technology:
At present, heat supply water often takes place in heating system let out the anti-phenomenon of usurping, cause heat energy to lose, the expection requirement of arriving is renderd a service in system's heat supply, in order to prevent to usurp hot water, adopts and add coloured or palatable substancess such as dyestuff, diesel oil, mud in heat supply water, hot water can't normally be used, the problem of usurping has solved, but because additive to the generation corrosion and the fouling of the heating system of boiler pipe, seriously influences the normal safe operation of heating system.
Summary of the invention:
The problem to be solved in the present invention provides the black corrosion inhibiting scale retarding agent that a kind of dyeing power is strong, nonpoisonous and tasteless, do not have corrosion and scaling, has overcome the existing anti-harm that hot water produces heating system of usurping.
Technical solution of the present invention is as follows: add first 1～99 weight part of water-soluble sulfuration in natrium humate 10～99 weight parts, also can select to add methylene radical two how sodium sulfonate 1～80 weight part or sodium salt 1～90 weight part, dust-proofing agent 1～90 weight part.
Described water-soluble sulfuration unit comprises coloured sulfide such as sulphur black, cupric sulfide, magnesium sulfide.
Under the normal pressure and temperature state, place airtight mixing vessel to mix above-mentioned substance, make product of the present invention.
Positively effect of the present invention is: that utilize natrium humate and corrosion-mitigation scale-inhibition characteristic water-soluble sulfuration unit and for the extremely strong dyeing power of water, the product good water solubility, diffusion rapidly, nonpoisonous and tasteless, even drink, can not cause intoxicating phenomenon yet, with low cost, use simply, have the effect that prevents the heat supplying pipeline fouling simultaneously.
Embodiment:
Embodiment 1
Get how sulfonic acid of methylene radical two that natrium humate 20g adds the solubilised sulphur black of 90g and 30g, throw in the airtight container and under 60 rev/mins rotating speed, mix, make product of the present invention.
Embodiment 2
50 kilograms of water-soluble cupric sulfides are mixed for 50 kilograms with natrium humate stir, add again 10 kilograms methylene radical two how sodium sulfonate and 30 kilograms of sodium-chlor under the normal temperature and pressure state, stirred 30 minutes, rotating speed is 80 rev/mins, makes product of the present invention.
Embodiment 3
Take by weighing 8 kilograms of natrium humates, 5 kilograms of solubilised sulphur blacks, methylene radical two how 2 kilograms of sodium sulfonates, 2 kilograms in yellow soda ash respectively, alleged raw material is put into sealing stirring container, 100 rev/mins were at the uniform velocity stirred 60 minutes, product of the present invention.
