High performance water reducing agent XNHPWA-800高性能減水劑

Product introduction  產(chǎn)品簡介       

    This product is the third generation of high-performance water reducer，which is currently high-efficiency water-reducing agent with the highest scientific and technological content, the best application prospect and the best comprehensive performance in the world.
    It has the advantages of low dosage,high water reducing rate,good cement adaptability,small slump loss and strong durability,etc. It is a non-toxic, non-corrosive, non-combustible safe high-performance water-reducing agent.
    Compared with the performance of similar products abroad, XNHPWA-800 high-performance water reducing agent has reached the current international advanced level in terms of technical performance indicators and cost performance.
  本產(chǎn)品是第三代高性能減水劑，是目前世界上科技含量最高、應(yīng)用前景最好、綜合性能最優(yōu)的一種高效減水劑。具有摻量低、減水率高、水泥適應(yīng)性好、坍落度損失小、耐久性強(qiáng)等優(yōu)點(diǎn)，是一種無毒、無腐蝕、不燃燒的安全環(huán)保型高性能減水劑。與國內(nèi)外同類產(chǎn)品性能比較，XNHPWA-800高性能減水劑在技術(shù)性能指標(biāo)、性價(jià)比方面都達(dá)到了當(dāng)今國際先進(jìn)水平。

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(chǎn)品適用于配制各種預(yù)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(xiàng)

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(chǎn)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(yīng)進(jìn)行混凝土試配試驗(yàn)，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(chǎn)品不得與其它減水劑混合使用。使用本產(chǎn)品之前必須將使用過其它減水劑的儲罐、攪拌機(jī)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(chǎn)品時(shí)，必須計(jì)量準(zhǔn)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(shí)必須嚴(yán)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(chǎn)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(yīng)置于陰涼、干燥處儲存，避免陽光直射、雨淋或負(fù)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(zhì)保期一年，超期產(chǎn)品經(jīng)試驗(yàn)驗(yàn)證合格后仍可繼續(xù)使用。
