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.


主要技术性能
The main technical performance

1、坍落度经时损失小：本产品单独使用或者与减水型产品(ZK-9系列)复配使用后可以有效减小混凝土经时损失，对于提高商品混凝土的中长距离运输(1-1.5h)及泵送更为有利。

2、优异的自保水性能，能使新拌混凝土具有良好的粘聚性、包裏性，不易离析、泌水，能提高混凝土的匀质性和工作性。

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。

5、本产品氯离子含量低、碱含量低，有利于提高混凝土的耐久性。

6、本产品生产过程无污染，不含甲醛，符合ISO14000环境保护管理国际标准，是一种绿色环保产品。

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.

注意事项
Notes

1、不能与松香类引气剂同时使用。

2、不能长时间使用铁质容器装载或储存，可用PE、PVC、PPR等容器。

3、不可与萘系外加剂混合使用。

4、要求精确计量,过掺会导致离析泌水,有延长混凝土凝结时间的可能性。

5、对砂石料中含泥量敏感，当砂的含泥量超过4%时，聚羧酸类外加剂减水性能明显降低。

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.
