Application
- concrete water reducer
It is a powder water-reducing agent with low air permeability. It belongs to anionic surface active material. It has adsorption and dispersion effect on cement and can improve various physical properties of concrete. It can be compounded into early strength agent, retarder, antifreeze, pumping agent, etc. - Sand preventing and sand fixing agents
- Tanning auxiliary in leather industry
- Water plugging agent for geology, oilfields, consolidated well walls and oil exploitation
It can improve the mobility of crude oil transportation and reduce energy consumption. - Textile dispersant
When it is used as dispersant and filler to disperse dyes, it can increase the chromaticity of dyes, make the coloring more even and shorten the grinding time of dyes. - As a binder for powder and granular materials
High strength, good stability and lubrication mould can be obtained in pelleting.It can help to improve the yield.
