Description
Technical field:
Product of the present invention relates to a kind of passivator and production method thereof that is exclusively used in boiler tubing.
Background technology:
Boiler and chemical pipeline are up to the present, never carry out passivation, come off layer by layer and cause boiler, pipeline in use very easily to produce oxidation corrosion, reduce work-ing life gradually, particularly the boiler inside and outside wall directly is subjected to high temperature oxidation and corrosion, under the condition of high temperature, calcium in the pipeline in the water, magnesium, iron, silicate plasma phase-polymerization and produce one deck bird nest, the serious fuel heat of isolating transfers heat to water and steam, impels heat passagely little by little to slow down, and rolls up fuel energy consumption.The outer wall of boiler and pipeline have no anti-gas phase high temperature oxidation resistance owing to be iron structure, have aggravated the oxidation corrosion of iron and steel.Cause boiler tubing or chemical pipeline weak point in work-ing life, big, the use cost cost height of energy consumption therefrom, original available passivation technology remedies the defective of castiron boiler tubing own, suffer from and in all age never have the inside and outside passivation technology of boiler tubing both at home and abroad till now, up to the present boiler tubing is never taked passivation technology both at home and abroad and cause work-ing life short, energy consumption is big, cost cost height.Product of the present invention is that boiler, pipeline are newly opened up a passivation technology, boiler, pipeline are behind passivation technology, can reduce the fouling in boiler tubing or the chemical pipeline, strengthen high temperature resistance, oxidizing sulfur dioxide corrosive nature, make boiler, pipeline can improve more than the twice work-ing life, reduce energy consumption more than 20%, reduce cost more than 50%.The more important thing is the passivation film that this passivator produces, is a kind of metal metallurgy smelting mating type passivation film, makes boiler, pipeline ectonexine metallic surface matrix convert the hybrid alloys type to by cast iron.High temperature oxidation resisting, corrosion-resistant, wear-resisting wiping, anti-sulfur dioxide corrosion, gasproof corrode or the like characteristic mutually.
Summary of the invention:
The purpose of this invention is to provide a kind of boiler dedicated, inner and outer walls of pipeline passivator and production method thereof, for boiler, pipeline are opened up a boiler, the novel passivation technology route of pipeline.For boiler, pipeline increase attractive and durablely, anti-high and low-temp oxidation and liquid, gaseous corrosion provide safeguard.Add product of the present invention, can make inner surface of pipeline form the inner complex of one deck densification, strengthened antiseptic property greatly, the original defective of boiler and chemical pipeline is resolved.Another object of the present invention provides the production method of this product.
The present invention is achieved through the following technical solutions:
1, determined PASSIVATION MECHANISM, according to the effect of mechanism anode potential electric current, improving product of the present invention, that the current density of the current potential system of metallic surface is reached passivation is critical, reach passivation, must make the current potential of metallic surface be higher than critical passivation potential.
2, optimize the formula rate scope of material and quantitatively select the production technique methods simultaneously according to PASSIVATION MECHANISM.
3, determine product processes of the present invention according to PASSIVATION MECHANISM in conjunction with composite mixed chemical alloy plating method.Characteristic of the present invention can make metallic surface and product of the present invention produce chelating and complex compound, makes the metallic surface matrix produce oxidation-go back source electric potential and reaches above critical potential and reach passive state, finally reaches metallurgical junction mould assembly mixing passivation film.Its feed composition of this product and parts by weight are: zinc phosphate 10-12 part, and SODIUM PHOSPHATE, MONOBASIC 5-7 part, nitrilotriacetic acid 3-5 part, diethylenetriamine 0.3-0.5 part, sodium aluminate 5-7 part, nickelous nitrate 5-7 part, phosphoric acid ferrimanganic 12-15 part, water 57-59 part is formed.
The production method of product of the present invention is: earlier water is allocated in the reactor, then the phosphoric acid ferrimanganic is joined into, stir molten intact back then the limit heat while stirring zinc phosphate, biphosphate are received, nickelous nitrate, nitrilotriacetic acid, diethylenetriamine put in by kind joining respectively, temperature is controlled at 60-70 ℃, insulated and stirred reaction chelated chromium closes after 30 minutes and stops to heat, and cooling 3 hours is left standstill in insulation, observes whether solution has become limpid transparency shape in the still, just calculate complexing and become passivator finished product, packing and selling.
This product has following characteristic effect: passivation film is fine and close and thick, is the metallurgical junction mould assembly, and long service life can make boiler, pipeline surfaces externally and internally matrix convert mixed type alloy rete to, increases the service life exponentially, reduces use cost, non-environmental-pollution.
One, specific implementation method
1, determine passivation scheme, according to PASSIVATION MECHANISM, screening material combination production formula.
2, at boiler, the pipeline characteristic and the technical problem that must solve separately, work out the special performance and the production process route of passivator, need the technological problems that solves in the passivation technology in the hope of satisfying boiler, the requirement of pipeline passivation technology, reaching.
3, filter out production technique according to qualifications, reach with this and produce the high-quality qualified product.
