First, the performance: evaporative cooling compact, small footprint, low investment, rapid evaporation, heat transfer efficiency, due to the above advantages, are widely used. However, all things are opposites, high heat transfer efficiency evaporative cooling, evaporation speed, while scaling too fast! To rust galvanized most evaporative cooling equipment, metal zinc is lively double metal, acid, alkali reactions are generally water treatment chemicals and cleaning agents will damage the zinc coating, resulting in evaporative cooling and cleaning cycles Water is extremely difficult market water treatment agent and cleaning agents can be used not on galvanized evaporative cooling, evaporative cooling of the user under scaling and fouling pitting damage galvanized layer and helpless! Evaporative cooling blowdown valve is also non-existent, because of the different parts of water, circulating water quality, water temperature is change at any time, evaporative cooling manufacturer can not determine the amount of sewage, coupled with increasingly strained water resources, in order to reduce emissions, almost All users are directly off the drain valve, causing evaporative cooling circulating water quality is getting worse! Almost all of these problems exist evaporative cooling! Evaporating special corrosion inhibitors, is a high-tech products clean up environmental 韩泰清 Engineering Chief Engineer for evaporative cooling characteristics of R & D, 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 evaporating special corrosion inhibitors, by supramolecular recognition and selective agents -assembly, the metal surface is better than nanometer film supramolecular film forming, thereby ensuring the zinc coating is not destroyed, while the effects of corrosion and scale inhibition of close to 100%. Second, the scope: various evaporative cooling water systems and other electrical, chemical, petroleum, fertilizer, paper, brewing and other precision industrial circulating water system, central air conditioning system, boiler, heating water heating systems can be used. Third, the technical indicators: Appearance: colorless to pale yellow liquid Solid content: ≥45% PH value: Neutral Relative density: 1.2 to 1.3 Solubility in water: miscible with water in any proportion Safety: non-toxic, non-flammable, non- explosion. Shelf life: cool and ventilated place for three years. Fourth, the product advantages: qd-866 evaporative cooling special corrosion inhibitor is stable, resistant to high PH value, high hardness, high turbidity, have excellent performance in the natural PH value makes the system run multiple high concentration of general water quality, K value of up to 10, is the general agent (K = 2 ~ 3) 3 ~ 5 times the amount of water saving. Both corrosion can also disperse scale of carbonates, phosphates, * salt, salt garnierite scale and so has excellent performance scale. Supramolecular concept was proposed in 1987 by French chemist, our water treatment experts - Han Taiqing Engineering first references to this principle to the field of industrial circulating water corrosion inhibitor, and developed the world's leading supramolecular corrosion inhibitors, qd-866 evaporative cooling special corrosion inhibitors can be widely used in various evaporative cooling water circulation system, the other power, chemical, petroleum, fertilizer, paper, brewing and other precision industrial circulating water system, central air conditioning system, boiler , hot water heating system can be used. Greatly improve heat transfer efficiency and water efficiency, extend system life more than 2 times, water, great material, energy, economic and environmental benefits! Fifth, use: 1, the amount of: adding 100-200mg / L according to the water quality. 2, the first time a high concentration of 0.2% better shock resistance into effect, according to the monitoring results can later online or acidity, conductivity meter and total solute instrument, automatic control unit PLC, and automatic drain valve and other instruments to achieve automatic medicine, automatic replenishment, automatic sewage water treatment technology programs. 3, the daily control of water pH 9 to 11, the total solute 2200 ~ 3000mg / L, automatic sewage and water can be, the operation is very simple. 4, to ensure safe and efficient operation of the system, a lot of water, materials, energy, greatly extending the life of the equipment. 5, clean up environmental protection with the pharmaceutical use of imported water to provide online monitoring instrumentation, 帕斯菲达加 dosing pump, dosing barrels, Siemens PLC automatic control system, imported electric discharge valve device composed of sets of fine, compact, easy to install, easy to operate, ensuring durable! Six, Packaging and storage: 25kg / barrel or ton drum, can be stored in a cool dry place for three years.
