Carbon steel passivation solution

Function and scope of
For ferrous metal (castings, forgings, sheet metal, etc.) rust-proof, widely used in machinery manufacturing, petroleum chemical industry, transportation, metallurgy, electricity, textile printing and dyeing industry, publishing and printing industry as well as military, mining, power generation plant, shipbuilding industry, medical equipment industry.
Product Features
Strong antirust ability
 No smell, no gas volatilization, do not pollute the operating environment
 does not contain the ingredients of fats and oils, after drying, the surface non greasy
 low foaming, easy to use
 All ingredients meet the biodegradability requirements
 does not contain nitrite, does not irritate skin, environmentally friendly
Use
(1) prior to use, the surface oil, rust and other foreign matter.
（2）With water before use the preparation of the working fluid, and mixing evenly, the dilution ratio can refer to the table and determined through experiments.
Dilution ratio and anti-corrosion effect:
The working fluid concentrations of rust-proof time (casting)
4 ~ 6% wt 3 to 7 days (working)
10 ~ 15% wt 3 to six months
20% wt and 12 months
Description: The above data are for reference only, not as a quality assurance or acceptance basis.
(b) anti-corrosion effect by the workpiece material, surface condition, climate, air pollution, as well as dilution water quality, construction method, the workpiece stacking and other factors, it is recommended that before the official use of small volume samples, select the appropriate concentration and construction methods, the lowest cost to obtain a satisfactory anti-corrosion effect.
3 jobs rust after treatment and dried and kept under seal extend the anti-rust of time.
Can be used to soak, brush or spray (shower), the way construction, brush or spray require parts of the surface to dry and be careful not to leak Tu. Recommendations for cracks, blind holes and other difficult painted to take corresponding measures.
4 workpiece coated with anti-rust solution to avoid direct contact or by other stains by hand, so as not to affect the anti-corrosion effect. If the conditions allow the packaging of the parts to extend the anti-rust of
