Precautions for use   使用注意事项


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.

   本产品(固含量20%)的掺量为胶凝材料总重量的0.6%~2.0%。常用掺量为0.8%~1.5%。使用前应进行混凝土试配试验,以求最佳掺量。

2、This product can be mixed directly with the cement into the mixer, or first add 40-70% concrete mixing water, and then add this product, the effect is better.

   本产品可随水泥加入搅拌机直接搅拌,或先加40~70%砼拌和水,再加入本品,效果更佳。

3、This product should not be mixed with other water reducing agents. Before using this product, the storage tanks, mixers and mixer trucks that have used other water reducing agents must be rinsed, otherwise the water reducing effect may be affected.

   本产品不得与其它减水剂混合使用。使用本产品前必须将使用过其它减水剂的储罐、搅拌机和搅拌车冲洗干净,否则有可能会影响减水效果。
4、When using this product, the measurement must be accurate and the concrete must be mixed evenly. Excessive addition of additives or uneven mixing may cause segregation of bleeding and difficulty in pumping.

   使用本产品时,必须计量准确,混凝土必须搅拌均匀。加入超量外加剂或搅拌不均匀可能导致离析泌水、泵送困难等现象。
5、Because this product has the characteristics of high water reduction rate, the slump is highly sensitive to water consumption, and water consumption must be strictly controlled when using it.

    由于本产品具有高减水率的特点,因此坍落度对用水量的敏感性较高,使用时必须严格控制用水量。

Packaging and storage  包装与贮存


1、This product is liquid and is packed in 1000kg plastic drums or plastic bags.

   本产品为液剂,采用1000kg塑料桶装或200±1kg塑料桶包装
2、Should be placed in a cool, dry place, sealed storage away from direct sunlight, rain or negative temperature environment preservation.

    应置于阴凉、干燥处储存,避免阳光直射、雨淋或负温环境保存。
3、The warranty period is one year, and the overdue products can only be used after being tested and verified.

    质保期一年,超期产品经试验验证合格后仍可继续使用。
