XNHPWR-300 superplasticizer XNHPWR-300高效減水劑

Product introduction 産品簡介

     High performance water-reducing agent is currently the largest and most widely used high-efficiency water-reducing agent in China. It is characterized by a high water-reducing rate (15%~25%), no air-entraining, and a small impact on the setting time. It is suitable for cement Relatively good performance, can be used in combination with various other additives.

    High performance water-reducing agents are often used to formulate high-fluidity, high-strength, and high-performance concrete. In use, it can greatly reduce the water consumption and significantly increase the strength of concrete at various ages. It can also save 10% or more of cement while maintaining a constant strength, which is cost-effective.

   In addition, the High performance water-reducing agent also has a small chloride ion content and does not corrode the steel bars; it can enhance the impermeability, freeze-thaw resistance and corrosion resistance of concrete, and improve the durability of concrete.

   高效減水劑是我(wǒ)(wǒ)國目前生(shēng)産量最大(dà)，使用最廣的高效減水劑，其特點是減水率較高(15%~25%)，不引氣，對凝結時間影響小(xiǎo)，與水泥适應性相對較好，能與其他各種外(wài)加劑複合使用。萘系減水劑常被用于配制大(dà)流動性、高強、高性能混凝土。使用中(zhōng)既能大(dà)幅度降低用水量從而顯著提高混凝土各齡期強度。又(yòu)能在保持強度恒定時，節約水泥10%或更多，性價比較高。此外(wài)，高效減水劑還具有氯離子含量微少，對鋼筋不産生(shēng)鏽蝕作用；能增強混凝土的抗滲、抗凍融及耐腐蝕性，提高混凝土的耐久性等特點。

    用于各類工(gōng)業與民用建築、水利、交通、港口、市政等工(gōng)程中(zhōng)的預制和現澆築鋼筋混凝土。适用于高強、超高強和中(zhōng)等強度混凝土，以及要求早強、适度抗凍、大(dà)流動性混凝土；适用于蒸養工(gōng)藝的預制混凝土構件；适用于做各種複合型外(wài)加劑的減水增強組分(fēn)(即母料)。

Precautions for use  使用注意事項

1、The content of this product (solid content 20%) is 0.6% to 2.0% of the total weight of the cementitious material. The usual dosage is 0.8%～1.5%. Before use, a trial mix test of concrete should be carried out to find the best mixing amount.
    本産品的摻量爲膠凝材料總重量的0.6%—2.0%。常用摻量爲0.8%—1.5%。使用前應進行混凝土試配試驗，以求最佳摻量。

2、When using this product, the measurement must be accurate, and the concrete must be mixed evenly.
    使用本産品時，必須計量準确，混凝土必須攪拌均勻。

3、The superplasticizer has a strong dispersing effect on the cement, which can greatly improve the fluidity of the cement mixture and the slump of the concrete, and at the same time greatly reduce the water consumption and significantly improve the workability of the concrete. However, some superplasticizers will accelerate the loss of concrete slump, and excessive mixing will cause bleeding.
     高效減水劑對水泥有強烈分(fēn)散作用，能大(dà)大(dà)提高水泥拌合物(wù)流動性和混凝土坍落度，同時大(dà)幅度降低用水量，顯著改善混凝土工(gōng)作性。但有的高效減水劑會加速混凝土坍落度損失，摻量過大(dà)則泌水。
