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(固含量20%)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、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.
本産品可随水泥加入攪拌機直接攪拌,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.
本産品不得與其它減水劑混合使用。使用本産品前必須将使用過其它減水劑的儲罐、攪拌機和攪拌車沖洗幹淨,否則有可能會影響減水效果。
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.
使用本産品時,必須計量準确,混凝土必須攪拌均勻。加入超量外(wài)加劑或攪拌不均勻可能導緻離析泌水、泵送困難等現象。
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.
由于本産品具有高減水率的特點,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.
本産品爲液劑,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、幹燥處儲存,避免陽光直射、雨淋或負溫環境保存。
3、The warranty period is one year, and the overdue products can only be used after being tested and verified.
質保期一(yī)年,超期産品經試驗驗證合格後仍可繼續使用。
