qd-8728 solid and efficient power plant boiler Pickling is clean up environmental leader, Chief Engineer R & D Engineering Han Taiqing Pickling, Han Taiqing Engineering is the national standard chemical cleaning HG / T2387-92 "industrial equipment, chemical cleaning quality standards, "the drafters and the person in charge of the drafting group, with 40 years of corrosion cleaning and industrial water treatment experience, led the development of the Korean Workers qd-8728 solid and efficient power plant boiler Pickling, more to meet the chemical cleaning the various needs of the industry, at the conclusion on the basis of the previous application experience, has successfully developed a scientific research, is one of my company's proprietary technology, the country's 26 provinces and more than 300 projects in the application of its main technical indicators have reached and exceeded the international advanced level, and the inhibition efficiency of 99%, is currently widely used in the industry in our country, leading technology and excellent corrosion inhibitors are unique. Especially for utility boilers * plus hydrofluoric acid pickling conditions, the other more secure pickling. First, the characteristics: versatility: qd-8728 corrosion inhibitor in addition to the solid nitrate for *, *, hydrofluoric acid, sulfamic acid, citric acid, and other * - hydrofluoric acid, glycolic acid - formic acid - ammonium hydrogen fluoride and other mixed acid. Efficiency: qd-8728 solid corrosion inhibitor in a variety of chemical cleaning with acid in an amount less than the normal amount of other types of corrosion inhibitors half, we can achieve the effect of other types of corrosion inhibition of the normal amount, and The steel has excellent ability to inhibit hydrogen absorption during pickling and excellent rejection of ferric ions accelerated corrosion, while allowing the metal pickling no pitting; especially mixed acid of hydrofluoric acid added in * solution, its efficiency is more prominent, even in the most demanding conditions pickling 50 ℃, 10% * + 1.37% hydrofluoric acid in the mix, just add 0.11% of qd-8728 inhibitor, 20 carbon steel corrosion rate was 0.7g / m2 · h, which is not only far below the boiler acid corrosion rate prescribed by the Ministry of Labor MEW and not more than 10g / m2 · h requirements, but also other types of corrosion agents can not match. Safety cheap: qd-8728 solid dosage inhibitor little, low cost; stable performance, simple operation, safe; odorless, non-toxic, environmental pollution; to carry, easy storage and transportation; and especially to avoid misuse slow danger caused by corrosion inhibitors. Second, the physical and chemical properties: Appearance: yellow powder milk Blastability: not explosive Odor: Aromatic Pickle Alkaline: slightly alkaline Flammability: Noncombustible toxicity: No toxicity Third, the scope: qd-8728 can be used with solid corrosion inhibitor in addition to various chemical cleaning outside nitric acid carbonate type remove all types of dirt, iron oxide type, * calcium, hybrid, siliceous type. qd-8728 is suitable for pickling inhibitor solid carbon steel, low alloy steel, copper and other metals and combinations of materials. Where there are all kinds of boilers, stove, heat exchangers, equipment jacket, air conditioning, heating systems and other equipment combinations industries (oil, chemicals, machinery, power, energy, electricity, telecommunications, transportation, light industry, culture, education, health and services industry, etc.), which pickling equipment may be employed. Fourth, use: According to the device structure, materials and scale type selection acid species and cleaning process. 0.11% is calculated according to the amount of qd-8728. qd-8728 solid corrosion inhibitor steps: adding water metering - qd-8728 solid inhibitor join measured, stir - according to conventional chemical cleaning process for cleaning. V. Storage: 25 kg plastic woven bag, stored in a cool dry place for 2 years.
