Lan-826 multi-purpose pickling corrosion inhibitor

 Lan-826 multi-purpose pickling corrosion inhibitor technology is another invention after the nitric acid corrosion inhibitor Lan-5 technology, which is in the leading and unique position both at home and abroad. In 1984, it passed the technical appraisal of the Ministry of Chemical Industry, and in June 1985, it won the third invention prize of the State Science and Technology Commission.

Performance Characteristics

1、Multi-use：Lan-826 corrosion inhibitor is applicable to both oxidizing acid and non-oxidizing acid; it is applicable to both many kinds of inorganic acid and many kinds of organic acid. (For example: ammonia citric acid, ammonia citric acid - hydrogen fluoride ammonia, hydrofluoric acid, hydrochloric acid, nitric acid, nitric acid - hydrofluoric acid, sulfamic acid, hydroxyacetic acid, hydroxyacetic acid - formic acid - hydrogen fluoride ammonia, EDTA, oxalic acid, acetic acid, phosphoric acid, sulfuric acid, etc.). It is the most widely used pickling corrosion inhibitor in the world today.

2, high efficiency: Lan-826 corrosion inhibitor in a variety of chemical cleaning acid, have excellent corrosion inhibition, in common conditions, so that the corrosion rate of the metal is not greater than 1mm / year, and has excellent inhibition of steel in the pickling absorption of hydrogen and excellent inhibition of Fe3 + accelerated corrosion of the ability of the metal does not produce holes in the pickling corrosion.

3, safe and inexpensive: Lan-826 corrosion inhibitor dosage is small, low cost, easy to operate, stable performance, odorless, no pollution of the environment, safe to use. Especially it can avoid the danger caused by misuse of corrosion inhibitor.

Physical and chemical properties

Appearance: tea-colored liquid Flammability: non-flammable and non-explosive Odor: aromatic Acidity and alkalinity: slightly alkaline

Scope of application

1、Lan-826 corrosion inhibitor can be used with a variety of chemical cleaning acid to remove calcium carbonate type, iron oxide type, calcium sulfate type, mixed type, siliceous type and other types of dirt.

2、Lan-826 corrosion inhibitor is suitable for acid cleaning of carbon steel, low alloy steel, stainless steel, copper, aluminum and other metals and their connecting structures of different materials. Chemical cleaning of various boilers, coolers, heaters, reactors, internal combustion engine cooling system, storage, water and sewage, air-conditioning systems and other equipment, such as petroleum, chemical, machinery, power, post and telecommunications, transportation, light industry, culture and education, health and service industries can be used.

Usage

1, according to the equipment structure, materials and scale type selection of acid and cleaning conditions. Determine the dosage of Lan-826 according to the selected acid according to the attached table.

2, Lan-826 corrosion inhibitor use steps: add measured water → add the recommended amount of Lan-826 corrosion inhibitor mixing → add measured acid mixing → cleaning according to conventional chemical cleaning process.
