  JW-IV萘系早強高效減水劑

       JW-IV 萘系高效減水劑主要成分是β-萘磺酸鹽甲醛縮合物,它對于水泥粒子有很強的分散作用,該產品具有非引氣,超塑化,減水率高,增強效果好,節約水泥,全面改善物理學性能等特點,特別適合具有高效減水和增強要求的常態混凝土和蒸養混凝土。本產品符合國標(GB8076-2008)一等品標準。

JW-IV萘系早強高效減水劑

  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

  ▉本品分為粉劑和液體兩種,粉劑呈棕褐色,水劑呈棕黑色。產品性能穩定,無毒,無刺激性和放射性,不含對鋼筋有銹蝕危險的物質。

  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.

  ▉增大流動性:水泥凈漿流動度大于200mm,當混凝土配合比不變時,摻入適量高效減水劑后,可將拌合料的流動性由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.

  ▉高效減水:按照國家現行標準GB8076-2008 檢測,其減水率達20% 以上。

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

  ▉提高混凝土強度:在單位膠凝材料相同條件下,摻本產品的混凝土強度1天,3天,7天,28天抗壓強度較基準混凝土可提高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. 適用范圍

  Scope of application

  產品可廣泛應用于各種現澆混凝土及預制混凝土構配件。特別適合于有早強,高強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

  ▉粉劑參量為水泥重量的0.5-1%,水劑摻量為1.3-2.0%。

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

  ▉粉狀固體直接使用時,應與水泥一起投入拌合物,切勿直接加在濕的砂,石表面;若配成溶液,應充分溶解。

  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.

  ▉為確保混凝土勻質性,攪拌時間要延長30-60秒。

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

  ▉為保證得到最佳的使用效果,建議用戶在使用本產品時,要根據工程技術要求和實際條件,參照以上說明對本劑的摻量,摻加方法及攪拌時間等做混凝土試配實驗,檢驗其和易性,凝結時間和強度是否滿足工程要求,施工過程中,要嚴格控制水灰比和減水劑摻量。

  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、包裝與貯存

  Packaging and Storage

  ▉粉劑采用內塑料袋外編織袋包裝,每袋凈重25kg 或 50kg 。水劑罐裝或協議包裝。

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

  ▉應在干燥環境中存放,水劑要密封,粉劑要注意防潮,避免結塊。

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

  ▉本產品有效期三年,粉劑堆放高度不宜超過10袋。

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