construction chemical
polynaphthalene sulphonate
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.
