ZK-7A聚羧酸系保坍剂 (I型)
ZK-7A Polycarboxylic acid water reducer
Slump type additive series

ZK-7A是本公司自主研发的一种具有保坍性能的聚羧酸减水剂,具有低掺量、高保坍、高早强、低收缩和对环境友好等特点。与国内同类前沿产品比较,本品适应范围更广,无需复合复杂的其它类型母液即可表现出优异的适应性。掺入本产品可大大提高混凝土的流动性, 改善混凝土的和易性及力学性能。是助推发展环保混凝土的保障型产品。

ZK-7A is the company independent research and development of a kind of slump retention properties of poly carboxylic acid water reducing agent,has many advantage,include low dosage,high slump loss,high early strength,low shrinkage characteristics.Compared with the domestic similar frontier products,the product is Widely adapted to a wider range,No other types of liquor can be complex exhibits excellent adaptability.This product can greatly improve the fluidity,of concrete,improve the work ability and mechanical properties of concrete.It is boost the development of environmentally friendly concrete protection products.

The main technical performance



3、与多数水泥具有良好的相容性, 解决了采用其它类减水剂与胶凝材料相容性问题。

4、混凝土收缩小: 可明显降低混凝土收缩, 显著提高混凝土体积、稳定性及耐久性。



7、经济效益好: 工程综合造价低于使用其它类型产品。

1.Slump loss of self-compacting concrete,This product is used alone or With the benefits of water reduction products(ZK-9 Series) compound after use can effectively reduce the loss of concrete,for the improvement of the long distance transportation(1-1.5h) and pumping more favorable.

2.Excellent water retention performance,can make the fresh concrete has good adhesion to gather and package,not easy to segregation and bleeding,can improve concrete homogenization.

3.Most of the cement has good compatibility,and it solves the problem of compatibility which between other kinds of water reducing agent and cement material.

4.Test and analysis results indicate that concrete can decrease the brittleness and promote the flexural strength and abrasion resistance.

5.The product has low chlorine ion content and low alkali content,which is beneficial for improving the durability of concrete.

6.No pollution in the production process of the product,This product contains no formaldehyde and fits the ecologist requirements.

7.The technology is characterized by low construction expense,high efficiency and high economic benefit.







1 Can not be used in conjunct1onwith any rosin type air entrained agent.

2. Can not be used iron container storage for along time,available PE,PVC,PPR and other materials container storage.

3. Do not mix with naphthalene admixture.

4. Can be weighed and measured,over mixed will lead to segregation and bleeding have the possibilily to prolong the setting time of the concrete.

5. It is sensitive to the content of day in sand and stone,when the content of sand is more than4%,the water reducing performance of the poly carboxylic acid additive was obviously decreased.

Packing deliver



3、本产品有效使用期限为一年,超过使用期限应经实验验证后使用 。

1.This product is colorless or light yellow liquid.

2.This product is non-toxic,tasteless,non corrosive,non flammable,can be transported by ordinary chemicals.

3.This warranty is good for one year after the date of the purchase of the product.More than the use of the term should be verified after experiment.
