  JW-IV萘系早强高效减水剂

       JW-IV 萘系高效减水剂主要成分是β-萘磺酸盐甲醛缩合物,它对于水泥粒子有很强的分散作用,该产品具有非引气,超塑化,减水率高,增强效果好,节约水泥,全面改善物理学性能等特点,特别适合具有高效减水和增强要求的常态混凝土和蒸养混凝土。本产品符合国标(GB8076-2008)一等品标准。

JW-IV萘系早强高效减水剂

  The fundamental ingredient of Naphthalene sulphonate superplasticizer is β-sulfonate naphthalene formaldehyde condensat. The product has the characteristics of non-air entraining, superplasticizing, high water reducing ratio, saving masses of cement and overall improving the physics performance. It is particularly suitable for water reduction and enhanced efficiency requirements of normal concrete and steam curing concrete. This product meets the national standard (GB8076-2008) First grade standards.

  一.主要性能

  The main Properties

  ▉本品分为粉剂和液体两种,粉剂呈棕褐色,水剂呈棕黑色。产品性能稳定,无毒,无刺激性和放射性,不含对钢筋有锈蚀危险的物质。

  This product is divided into two kinds: powder and liquid , powder for tan powder and water for brown viscous liquid. The product performance is stable, non-poisonous, odorless, non-flammable, and non-corrosive to steel bars.

  ▉增大流动性:水泥净浆流动度大于200mm,当混凝土配合比不变时,掺入适量高效减水剂后,可将拌合料的流动性由0-50mm 提高到150-250mm。

  Increasing fluidity: when the fluidity of cement paste exceed 200mm, and the concrete mix is not change, mixed with the right amount of superplasticizer can make the mixes fluidity of 0-50mm up to 150-250mm.

  ▉高效减水:按照国家现行标准GB8076-2008 检测,其减水率达20% 以上。

  High-efficient water reducing: according to the current national standard GB8076-2008 testing, the reduction rate of more than 20%.

  ▉提高混凝土强度:在单位胶凝材料相同条件下,掺本产品的混凝土强度1天,3天,7天,28天抗压强度较基准混凝土可提高60-70%,50-60%,40-50%,33-42%。

  Improving concrete strength: units under the same conditions cementitious material. Compared to the reference concrete, mixing with concrete strength of this product 1day, 3days, 7days, 28days , the compressive strength can be increased to 60-70%, 50-60%, 40-50%,33-42%.

  二. 适用范围

  Scope of application

  产品可广泛应用于各种现浇混凝土及预制混凝土构配件。特别适合于有早强,高强或耐久性要求的混凝土。

  Products can be widely used in various Cast-in-situ concrete and precast concrete structures and fixtures. Particularly suited to early strength, high strength or durability require concrete.

  三.使用方法

  The use of methods

  ▉粉剂参量为水泥重量的0.5-1%,水剂掺量为1.3-2.0%。

  Powder parameters of 0.5-1% by weight of cement, liquid dosage is 1.3-2.0%.

  ▉粉状固体直接使用时,应与水泥一起投入拌合物,切勿直接加在湿的砂,石表面;若配成溶液,应充分溶解。

  When powdered solid used directly, should be put into cement with mixing things together, not directly added to the sand, stone surface wet; If the match into solution, should be fully dissolved.

  ▉为确保混凝土匀质性,搅拌时间要延长30-60秒。

  To ensure homogeneity of concrete, the mixing time should be extended 30-60 seconds.

  ▉为保证得到最佳的使用效果,建议用户在使用本产品时,要根据工程技术要求和实际条件,参照以上说明对本剂的掺量,掺加方法及搅拌时间等做混凝土试配实验,检验其和易性,凝结时间和强度是否满足工程要求,施工过程中,要严格控制水灰比和减水剂掺量。

  In order to achieve the best results, we recommend that users should according to the technical requirements of the project and the actual conditions, referring to the above description of the content of this product, mixing methods and mixing time for concrete specimens with experiments to test its workability, setting time and strength meets the project requirements, the construction process, to strictly control the water-cement ratio and superplasticizer dosage.

  四、包装与贮存

  Packaging and Storage

  ▉粉剂采用内塑料袋外编织袋包装,每袋净重25kg 或 50kg 。水剂罐装或协议包装。

  For powder: woven fabric bag with plastic liner. net weight 25kg or 50kg. For liquid: Canned or packaged according to agreement.

  ▉应在干燥环境中存放,水剂要密封,粉剂要注意防潮,避免结块。

  It should be stored in a dry environment, water should be sealed, powder should pay attention to moisture, avoid caking.

  ▉本产品有效期三年,粉剂堆放高度不宜超过10袋。

  This product is valid for three years, powder stacking height should not exceed 10 bags.
