Petrochemical plant corrosion and scale inhibitor LD-ZG002 - Cooling Water Chemicals

Petrochemical plant corrosion and scale inhibitor LD-ZG002

Features

Product property:

ZG002 is composed of a variety of organophosphorus carboxylic acids, polycarboxylic acids, sulfonate copolymers, corrosion inhibitors, special interface active agents and other composite corrosion inhibitor, using organic phosphate on the metal surface to form a protective film to play an corrosion inhibition effect, At the same time, calcium carbonate, calcium sulfate and calcium phosphate have good chelating dispersion and lattice distortion. According to the principle of reasonable proportioning, the synergistic effect has the characteristics of high corrosion inhibition rate, high temperature resistance, strong scale resistance and difficult decomposition.

Range of application:

This product is mainly used in scale and corrosion inhibition of open circulating cooling water system such as power plant, oil refining, chemical industry, chemical fertilizer, steel-making and so on. It has good corrosion inhibition effect on carbon steel, copper, aluminum, stainless steel and so on. Wide application of water quality.

Usage method:

Depending on the water quality and process conditions, the general dosage of 5-30ppm is to add the corrosion and scale inhibitor needed every day to the plastic dosing drum (or box). In order to facilitate the use of water dilute after the metering pump or through the control valve door medicine at the inlet of the circulating pump (that is the catchment pool outlet) continuous addition.
