Corrosion inhibitor SJ-K2.doc Inner production and sales of concrete corrosion inhibitor manufacturers - rust preservative manufacturers Tel: 15726257213 Liu a, characteristic corrosion inhibitor SJ-K2.doc corrosion inhibitor is a highly corrosion inhibitor, mixed concrete can prevent or delay the corrosion, thus extending the life of the structure, in the international category, are "incorporation-type." This product is suitable for ordinary Portland and slag cement concrete, fly ash, slag powder, silica fume and commonly used superplasticizer has good compatibility. This product is air-entraining agents are selective; when used in more than 25 ℃, there are obvious early strength, procoagulant effect, and the impact of losses slump can take retarding measures when necessary. It forms a dense protective layer in the steel surface, when harmful ions invade the concrete structure, it can effectively inhibit, prevent and delay the process of steel corrosion in an electrochemical reaction, thereby extending reinforced concrete knot. The life of two configurations, corrosion inhibitor main technical indicators performance test standard indicators project a measured value rust resistance, salt erosion potential test no rust no rust 0 ~ -250mV potential -179mV 2, wet cold (60 times ) no rust no rust 3, electrochemical displacement test Pass Pass test a performance impact on the concrete compressive strength is not reduced to 125% (compared to the baseline group) 2, impermeability is not reduced 110% (compared to the baseline group) 3, the initial setting Time / min -60 ~ + 120 (baseline comparison group) -50 (comparing baseline group) Note: Test basis: YB / T9231-98 "corrosion inhibitor use technical regulations." Third, the use of corrosion inhibitor Press "corrosion inhibitor use technical standards" (YB / T9231-98) and other design specifications implemented. This product is mainly used for corrosion in chloride-based environments such as marine and coastal engineering, the use of sea sand and chlorine salt corrosion of industrial buildings. Fourth, the corrosion inhibitor performance concrete air content ≤4% water rate of bleeding than ≤100% setting time difference (early and final setting) -90 ~ + 120min compressive shrinkage ratio ≥100% 28d than ≤135% five , corrosion inhibitor performance tests in line with national industry standards a "corrosion inhibitor use technical regulations" (YB / T9231-98). Pilot project provides indicators 1, 2 salt water immersion project no rust, wet thermal cycling test (60 times) no rust (blank obvious rust) 3, no rust steel corrosion electrochemistry experiment 2, "harbor engineering concrete structure corrosion technical specifications "(JTJ275-2000). Six, corrosion inhibitor for use a recommended dosage is: slightly corrosive environment (1) general industrial buildings, bridges, etc., the recommended dosage is recommended for 20 kg / m3. (2) harbor engineering, coastal construction and other severe corrosive environment, the recommended dosage is recommended for 30 kg / m3. 2, the goods and cement, aggregates the mixer while adding dry mix, stir together water, stir, and stir appropriate to extend the time to ensure that the concrete mix well. 3, when used with other admixtures composite should do first concrete test match, to determine their suitability; not use air-entraining type agents. Preparation of concrete materials used should be consistent with "building gravel, crushed stone" GB / T14685-2001 and "building sand" GB / T14684-2001. 4, the product is 25 kg bags, storage period of one year, if slightly soluble in water to absorb moisture caking use in the transportation, storage process should avoid rain, moisture, cool and ventilated, away from flammable objects, open flame is prohibited; the operator should wear masks, rubber gloves. Seven, corrosion inhibitor note 1, generally dry mixed method, can also be dissolved in water mix (including some insolubles). Be sure to stir, stirring time may be extended. This product is slightly water-reducing effect, may be appropriate to reduce the water flow while maintaining the original degree. 2, when shared with other additives, should first adding this product to be uniformly mixed with cement (concrete) before adding other additives. 3, the product can play a more effective role in the quality of concrete, must comply with the relevant specifications and design requirements, do first concrete mix ratio test, to ensure the quality of concrete and compactness. 4, incorporating corrosion inhibitor-related regulations, norms: "industrial buildings anticorrosion design specifications," "marine concrete structure design specifications," "saline soil building regulations", "Highway Engineering admixture norms" and so on.
