Green home BQ-202 pre-film
First, product performance
BQ-202 pre-film is a highly effective pre-film,
the main material from a wide range of complexing agent, dispersant, into a film, the composition of surfactants, organic complexes of oxygen atoms not shared with the electronic iron, calcium metal ions or positive charge with some of the iron atom chemical adsorption, the formation of coordination bond, and finally produce a layer of insoluble membrane sequestration of carbon steel and other metal covering the surface, this membrane resistance and make big Corrosion of metals and dielectric isolation in the water, which play a role in inhibiting corrosion.
BQ-202 pre-film has a film speed, as well as uniform membranaceous, chemical stability, low corrosion rate. BQ-202 pre-film on the water quality from water adaptable copper, iron ions and other harmful interference, BQ-202 pre-film cycle of the main cooling water system for the new device drivers or system for post-maintenance equipment and heat pre-membrane channels, so that the metal surface to form a protective film to prevent the run-time of carbon steel, copper alloy, stainless steel and other corrosion materials.
Second, the use of methods
BQ-202 film plus pre-concentration is generally 200-500mg / L. Time for pre-film cold 48-72 hours, 24-48 hours hot.
C, packaging and storage
BQ-202 pre-film with plastic barrel, 25kg. BQ-202 pre-stored in a cool film, the storage period of twelve months.
BQ-202 pre-film product for the acid, should be avoided and the skin, eyes and other contact, contact with a large number of water washing after the application.
