Corrosion and scale inhibitor for closed circulating water system

JL-H752 corrosion and scale inhibitor main components: molybdate, tungstate, phosphonic acid, alkolamide, non-ferrous metal protective agents and auxiliaries.

Physical and chemical index:

Performance characteristics:

(1) The rapid formation of a protective film mixed with deposited film and oxide film on the metal surface inhibits the corrosion of carbon steel, copper and copper alloy by oxygen and corrosive ions (Cl-, SO42-), and the corrosion inhibition effect is outstanding;

(2) It has a good dispersion, chelation and solubilization effect on calcium carbonate, calcium phosphate and iron oxide in water, and then plays a good scale inhibition and dispersion effect, and keeps the metal surface clean all the time;

(3) Good thermal stability, not easy to decompose and reduce efficiency, do not have to worry about environmental pollution caused by sewage and impact load on sewage treatment, in line with environmental protection requirements.

Application: Closed circuit circulating cooling water system with groundwater or river water directly as a special efficient scale and corrosion inhibitor, widely used in chemical industry, metallurgy, electric power, petrochemical, air conditioning and other closed cycle cooling water system.

Usage: The dosage varies according to the water quality index and parameters, the dosage is calculated according to the supplementary water amount, and the dosage concentration is controlled at about 50-200 mg/L. Suitable for PH 7.0-10.0.

Packing and storage: 25kg, 200kg, 1000kg plastic drum packaging, stored in a cool and dry place, storage period of 12 months, handling carefully to prevent impact.

The slow-release effect was obtained by SEM scanning electron microscope before and after use

The corrosion and scale inhibitor of our company can form a protective film mixed by oxidation film, adsorption film and deposition film on the metal surface, so that the metal is in a passivation state, so as to separate the metal from the corrosive gases and ions in the water, and ensure that the metal is not corroded in hundreds of thousands of Cl-circulating water.

The scale inhibition effect under SEM scanning electron microscope before and after dosage

During the operation of circulating water system, the dissolved scaling substance will precipitate into scale when it reaches the supersaturated state. After adding the corrosion and scale inhibitor of our company, the agent acts on the precipitation process of the scaling material, and makes it become water slag through lattice distortion, dispersion and exclusion, thus ensuring that the circulating water system does not scale for a long time.
