1. Product content
The addition of JH-FZ rust inhibitor into concrete can prevent or greatly slow down the corrosion rate of steel bars, thereby extending the service life of the structure: This product overcomes the appearance of sodium nitrite in concrete Defects of alkali-bone reaction and electrochemical erosion are eliminated, and the physical and mechanical properties and durability of concrete are improved. 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. Scope of use
1. Suitable for rust prevention of cast-in-place concrete, components, concrete structure engineering repairs, buildings using sea sand, urban overpasses and roads with heavy erosion.
2. Configure concrete with a thin protective layer and concrete mixed with a certain amount of chlorine salt and other harmful components of steel bars.
3. Concrete is used in unfavorable geological areas and ocean waters such as coal strata, gypsum strata, free strata, saline strata, salt lakes, coastal salt pans, coastal ports, seawater permeability areas, etc. containing sulfate and magnesium ions.
3. Main functional 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 length of steel bars. Service life of concrete structures in aggressive environments.
3. Under moderate corrosion conditions, it can completely replace the outer coating protection of reinforced concrete structures (such as the use of perchlorethylene anticorrosive coatings, etc.).
4. Suppress or reduce the corrosion of steel bars or other embedded metals in concrete.
5. It has the comprehensive effects of reducing water, compacting and improving the strength of concrete, improving and improving the self-protection ability of concrete, and can partially or completely replace concrete water-reducing agents.
6. Steel bar corrosion items:
(1) Salt water immersion items: no corrosion
(2) Dry, wet and hot cycle test: no rust (blank details for corrosion)
(3) ) Electrochemical test of steel bar corrosion: no corrosion.
4. Parameter dosage
Based on the purpose and requirements of use, the dosage is 2-3% in general rust prevention and rust-inhibiting 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.
