YJ-R505 composite amino alcohols, organic corrosion inhibitor

YJ-R505 composite amino alcohols, organic corrosion inhibitor consulting 13716267347 YJ-R505 is mixed type (DCI) composite amino alcohols, organic rust inhibitor an internal, by a variety of different types of alcohol Amines and rust with a specific role The inorganic component of the composite, does not contain nitrite. After the concrete was added YJ-R505, rust inhibitor of the different components can be formed on the steel surface adsorption film, precipitate film and an oxide film, play a blocking harmful substances in contact with the steel surface, prevent or delay the time to occurrence of corrosion; Meanwhile YJ-R505 has a water-reducing effect, can effectively improve the performance of concrete mixture and improve concrete impermeability, reduce the rate of diffusion and diffusion coefficient of chloride ions of dissolved oxygen. The combined effect of both, and ultimately to improve the durability of concrete structures, concrete structures extend service life. Scope: 1, hydraulic structures (dams, bridges, tunnels, etc.), marine construction (berm, docks, etc.), underground facilities (subway, underground parking), strengthening and repairing building foundations and concrete structures. 2, various types of industrial sewage tank, water towers, storage tanks, silos, tanks, cave storage libraries. 3, the use of sea sand building, using the structure of ice salt. 4 prestressed structures, roads, railways and other important buildings. Rust Performance Project standard indicators YJ-R505 detect potential indicators of salt water immersion test 0 ~ -250 mv potential 0 ~ -200 mv drying concrete leaching test (relative to non-doped rust inhibitor) reduced by more than 95 percent rust area corroded area decreased 98% Performance Project standard indicators over concrete mixed with YJ-R505 rust inhibitor compressive strength of concrete performance ratio,%> 90 100 to 120 setting time, min -120 ~ + 120 -60 ~ + 120 impermeability is not reduced without reducing the recommended doped the amount of the type of environment unilateral concrete content (kg / m3) mildly corrosive environment in general construction, underground engineering, prestressed channel, the water level of prestressed structures 8-10 severe corrosive environment marine harbor engineering change zone and splash zone structure, bridge, Chloride content greater than 5000 mg / L of saline land area, 10 to 16 construction sewage treatment pond structure Note 1, YJ-R505 is slightly water-reducing effect, may be appropriate to reduce water flow while maintaining the original degree. 2, the product adapted to the common cement, special cement and fly ash, slag powder and silica fume mineral admixture, with common water reducer has good compatibility. 3, added to the product of the concrete work must first be done with the ratio test. 4, high-quality concrete in order to more effectively play its role, must comply with the relevant specifications and design requirements to ensure the quality and solidity of concrete. 5, the product is a liquid, 50 kg or 200 kg drums, to be sealed, dark, cool place, storage period of six months. Experimental study YJ-R505 composite amino alcohols concrete corrosion inhibitor rust performance test YJ-R505 composite amino alcohols rust properties, including salt water immersion test and drying concrete leaching test, specific test method reference YB / T9231 "rust inhibitor the use of technical regulations "to. Notes: 1, salt water immersion test: sodium chloride solution YJ-R505, the steel clean as new, does not appear any rust, rust effect is remarkable. 2, seawater Durable Concrete Raw materials:. 1, Po 42.5 2 Portland cement, fly ash, slag, silica fume and other admixtures 3, the maximum particle size of not more than 25 mm in a non-reactive aggregate 4, shall 5 using sea sand and artificial sand, water reduction of at least 25% efficient additive, concrete should be added the right amount of complex amino alcohols concrete corrosion inhibitor in raw materials restrictions chloride ion content. 3, the use of 1, YJ-R505 incorporated in concrete, preventing or delaying steel corrosion in the international category, are "incorporation-type" (DCI). 2, the YJ-R505 and metering water, cement, aggregates while adding concrete mixer, an appropriate extension of the mixing time to ensure uniform mixing. 3, when the YJ-R505 combined use with other additives, should do first concrete test feature to determine their suitability; preparation of concrete materials used should be consistent with "building gravel, crushed stone" GB / T14685 and "building sand" GB / T14684. 4, YJ-R505 powder if slightly soluble in water to absorb moisture caking use, liquid surface of the product may be foam, does not affect use. In the transport, storage process should avoid rain, moisture, cool and ventilated, away from flammable objects, open flame is prohibited. 5, the operator should wear masks, rubber gloves and other necessary protective measures. Waste, waste toner can not be dumped
