Main use: This product has won the third-class invention award of the State Science and Technology Commission, and has been listed as a national key scientific and technological achievement promotion project by the State Science and Technology Commission. It is another international advanced technology after the Lan-5 nitric acid pickling inhibitor technology. In the metal pickling process, the acid corrosion of the metal body is slowed down, and the corrosion inhibition effect is good in various chemical pickling processes.
Lan-826 multi-purpose pickling corrosion inhibitor
Main use: This product has won the third-class invention award of the State Science and Technology Commission, and has been listed as a national key scientific and technological achievement promotion project by the State Science and Technology Commission. It is another international advanced technology after the Lan-5 nitric acid pickling inhibitor technology. In the metal pickling process, the acid corrosion of the metal body is slowed down, and the corrosion inhibition effect is good in various chemical pickling processes. Under normal use, the corrosion rate of the metal is greatly reduced, and the ability of the steel to absorb hydrogen during the pickling process is well suppressed, the "hydrogen embrittlement" of the steel is avoided, and the corrosion of the metal by Fe3+ during the pickling process is inhibited, so that the metal is No pitting corrosion occurs. Suitable for various inorganic acids, organic acids, oxidizing acids, non-oxidizing acids, such as hydrochloric acid, nitric acid, nitric acid-hydrofluoric acid, sulfuric acid, phosphoric acid, hydrofluoric acid, sulfamic acid, citric acid, oxalic acid, acetic acid, EDTA , various kinds of pickling acids such as NTA and HEDP.
Outstanding features: This product is light yellow or light red liquid, stable performance, simple operation, small dosage, high efficiency, low cost, non-toxic and odorless, no pollution to the environment; low corrosion to metal matrix, high corrosion inhibition rate, process There is no acid mist in it, it is safe to use, especially to avoid the danger caused by misuse of corrosion inhibitor. 1. It can be used with various chemical cleaning acids to remove various types of dirt such as calcium carbonate type, iron oxide type, calcium sulfate type, mixed type and silicon type. 2. It is suitable for pickling with carbon steel, low alloy steel, stainless steel "target=_blank> stainless steel, copper, aluminum and other metals and their different materials. 3, various boilers, coolers, heaters, reactors, Internal combustion engine cooling system, storage, water and sewage, air conditioning systems and other equipment 4, petroleum, chemical, machinery, power, post and telecommunications, transportation, light industry, culture and education, health and service industries can be used.
Physical and chemical indicators: Appearance: light yellow or deep red liquid; Specific gravity: >1.0; Acidity and alkalinity: weakly alkaline; Flammability: Non-combustible and non-explosive. Usage: 1. Dosing: The concentration of corrosion inhibitor is generally 0.5-2. %(weight). First, measure the corrosion inhibitor 1:10-20 with water (water is 50-60 degrees warm water), stir until completely dissolved, then add to the remaining metered water, stir evenly; 2, with acid wash: will measure The acid is slowly added to the above-mentioned prepared liquid, and the acid is completely dissolved by stirring constantly, and the solution is uniformly mixed and then used. If there is acid mist, please add a small amount of "Yunqing brand pickling antifogging agent"; if the rust and scale are not cleaned, the speed is slow, please add "Yunqing brand-acid picking accelerator"; if you want to solve it once For all the above problems, please add “Yunqing brand pickling additiveâ€; 3. Pickling process conditions: In the above acid pickling solution: (1) The concentration of inorganic acid used is generally 3-10% by weight, not more than 20 % (weight); use at room temperature, the temperature can not exceed 45 ° C, otherwise the corrosion inhibitor is easy to fail, accelerate the corrosion of acid on the metal. (Inorganic acid includes hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid, hydrofluoric acid, etc.) (2) The organic acid is generally used at a concentration of 3-20% by weight, at normal temperature or heated to 60-90 degrees, and the temperature or concentration is not too high. Otherwise, the corrosion inhibitor may fail, speeding up the corrosion of the acid by the acid. (Organic acids include sulfamic acid, citric acid, oxalic acid, acetic acid, EDTA, NTA, HEDP, etc.). If you are using it for the first time or have not used it, you must use a small amount of trial and then use it in large quantities.
Matters needing attention: 1, this product is slightly corrosive, if splashed into the eyes, mouth, please rinse with water immediately, strictly forbidden; 2, after the liquid, should be used in time; sealed in a cool place.
Packing specification: plastic bottle, 1 kg / bottle, 24 bottles / box; plastic barrel, 25 kg / barrel.
