1. Product content
JH -FZ rust inhibitor can prevent or greatly slow down the corrosion rate of steel bars when added to concrete, thereby extending the service life of the structure: This product overcomes the defects of sodium nitrite causing alkali bone reaction and electrochemical corrosion in concrete, and improves concrete. physical and mechanical properties and durability. This product can effectively prevent or slow down the corrosion of steel bars by harmful components such as chloride ions and sulfate ions. It can be widely used in reinforced concrete projects with rust prevention requirements such as roads, bridges, ports, and coastal areas.
2. Applicable scope
1. Suitable for cast-in-place concrete, components, concrete structure engineering repair and rust prevention, buildings using sea sand, urban overpasses and roads with heavy erosion.
2. Configure concrete with a thin protective layer and add a certain amount of chlorine salt and other steel bars Hazardous ingredients in concrete.
3. Configure coal-bearing strata, gypsum strata, and free Concrete is used in unfavorable geological areas such as strata, saline strata, salt lakes, coastal salt fields, coastal ports, seawater penetration areas, and ocean waters.
3. Main performance indicators
1. Appearance: gray powder
2. Mixed into concrete to passivate the surface of steel bars and delay the corrosion rate of steel bars by about 6 times, greatly extending the service life of reinforced concrete structures in corrosive environments.
3. Under moderate corrosion conditions, it can completely replace the outer coating of reinforced concrete structures. Protection (such as using perchlorethylene anticorrosive coating, etc.).
4. Suppress or reduce the corrosion of steel bars or other embedded metals in concrete.
5. It has the comprehensive performance of water reduction, density and improvement of concrete strength, improvement and progress The self-protection ability of concrete can partially or completely replace the concrete water-reducing agent.
6. Steel corrosion project:
(1) Salt water immersion project: no rust
(2) Dry, wet, cold and hot cycle test: no rust (blank details for rust)
(3) Steel bar corrosion electrochemical test: no corrosion.
4. Parameter dosage
According to the purpose and requirements of use, the dosage is 2-3% in general anti-rust and anti-rust environments; the dosage in harsh environments such as coastal or saline-alkali areas is 3-4%.
5. How to use
Dry powder can be directly mixed into concrete for use. The mixing time of concrete should be extended: it can also be used in combination with other admixtures.
6. Packaging and storage
This product is packaged in woven bags, 50 kg/bag. During storage, precautions should be taken to prevent rainforest, flooding, and open-air stacking.
