| Other Information |
Grade HA has large molecular structure, so little it can stabilize the latex, it is a good dispersant for butadien styene rubber and other latex, or used as softener of vat dye, levelling agent, softener of tannage or water removing agent.
Grade A , B and C are mainly used in concrete admixtures, watertreat industries. Its high purity makes cement paticles with high dispersancy, low foaming, high range water reducing and obvious strengthening so that we can get advantages of accelerating project mould turnover and construction speed, and also saving cement, improving cement mobility and workability. It is a high range concrete admixture of concrete cast-in-place, prefabricating, pump and curing.
It has a good adaptability to various cements and it is no erodent to reinforcing bar and nonpoisonous and pollution-free. It has been applied to the highway, bridge, tunnel, water conservancy hydroelectric project, port, quay, skyscraper, power engineering, industrial civil building, prestressing force component and high range concrete etc.
It is very soluble in water and are compatible with most ingredients. The compound is non-toxic and does not cause pollution to the environment. | |
