Scope of application 適用范圍

    This product is suitable for the preparation of various high-performance concretes such as precast concrete, self-leveling concrete, concrete with high water reduction and low water-cement ratio, and durable concrete.
   本產品適用于配制各種預制混凝土、自流平混凝土、高減水低水灰比混凝土、耐久性混凝土等高性能混凝土。

 

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.
   本產品的摻量為膠凝材料總重量的0.6%—2.0%。常用摻量為0.8%—1.5%。使用前應進行混凝土試配試驗,以求最佳摻量。

2、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.
    本產品不得與其它減水劑混合使用。使用本產品之前必須將使用過其它減水劑的儲罐、攪拌機和攪拌車沖洗干凈,否則有可能會影響減水效果。

3、When using this product, the measurement must be accurate and the concrete must be mixed evenly.
    使用本產品時,必須計量準確,混凝土必須攪拌均勻。

4、Because the water reduction rate of concrete mixed with XNHPWA-800 polycarboxylic acid high-performance water-reducing agent is relatively large, the slump is highly sensitive to water consumption, and water consumption must be strictly controlled during use.
   由于摻用XNHPWA-800聚羧酸高性能減水劑混凝土的減水率較大,因此坍落度對用水量的敏感性較高,使用時必須嚴格控制用水量。

Packaging and storage  包裝與貯存

1、This product is liquid and is packed in 1000kg plastic drums or plastic bags.
   本產品為液體,采用1000kg塑料桶裝或200±1kg塑料桶包裝。

2、Should be placed in a cool, dry place, sealed storage away from direct sunlight, rain or negative temperature environment preservation.
   應置于陰涼、干燥處儲存,避免陽光直射、雨淋或負溫環(huán)境保存。


3、The warranty period is one year, and the overdue products can only be used after being tested and verified.
    質保期一年,超期產品經試驗驗證合格后仍可繼續(xù)使用。
