Properties:
(1) Widely used: it is suitable for the pickling of hydrochloric acid, nitric acid, hydrofluoric acid, nitric acid + hydrofluoric acid, ammonia citric acid, ammonia citric acid + ammonium hydrofluoric acid, sulfamic acid, hydroxyacetic acid, hydroxyacetic acid + formic acid + ammonium hydrofluoric acid, EDTA, oxalic acid, phosphoric acid, acetic acid, sulfuric acid, and other kinds of inorganic, organic and mixed acids, and it is one of the most widely used pickling corrosion inhibitors at present.
(2) High efficiency: in a variety of chemical cleaning media have excellent corrosion inhibition, commonly used conditions of the metal corrosion rate of less than 1g/m2-h, has excellent resistance to pickling hydrogen seepage and inhibition of Fe3+ corrosion ability, pickling metal does not produce holes corrosion.
(3) Cost-effective: small dosage, easy operation and safe use.
Usage:
(1) Cooperate with various chemical cleaning media to clean carbonate-type, iron oxide-type, sulfate-type, mixed-type and siliceous-type scale.
(2) It is suitable for acid cleaning of carbon steel, low alloy steel, stainless steel, copper, aluminum and other metal equipment and equipment made of combined materials.
(3) It is suitable for the cleaning of various heat exchanging equipments in petroleum, chemical, machinery, metallurgy, electric power, transportation, cooling, life and other industries.
Usage:
(1) When the circulating water system is cleaned online, according to the amount of water retained in the circulating water system, 200-500mg/L can be injected by impact, and the organic cleaning can be carried out only after circulating for 2h.
(2) Single machine cleaning, first in the cleaning tank filled with water, according to the ratio of 2.5 ‰ to 3 ‰ to join the product mixed well. Then add the acid can be prepared into the acid cleaning solution.
Packing and storage:
Packed in plastic drums, net weight 25kg per drum, it is suitable to be stored in a cool place, avoiding high temperature and direct sunlight. Storage period: 12 months.
