poly naphthalene sulfonate formaldehyde( PNS)

Product Description

Wuhan Xinyingda Chemicals Co., Ltd, are mainly produce naphthalene sulfonated sodium salt, which have been used in construction, textile are for water reducer and dispersing agent.

A dispersant or a dispersing agent or a plasticizer or a superplasticizer is either a non-surface active polymer or a surface-active substance added to a suspension, usually a colloid, to improve the separation of particles and to prevent settling or clumping. Dispersants consist normally of one or more surfactants, but may also be gases.
Which kinds of our products are dispersant?
 Among our products, sodium/calcium lignosulphonate, ferrochrome lignosulphonate, sodium naphthalene formaldehyde are all the dispersing agent, which can be widely used in construction, oil drilling, emulsifier, gypsum wallboard........

As a dispersing agent, it can be widely used in blow areas:
1)Concrete
Dispersants/plasticizer/superplasticizers are used in the concrete mix (sand, stone, cement and water) to lower the use of water and still keeping the same slump (flow) property. This makes the concrete stronger and more impervious to water penetration., such as, sodium/calcium lignosulphonate, sodium naphthalene formaldehyde etc...
2）Gypsum wallboard
A dispersant/plasticizer( sodium/calcium lignosulphonate, sodium naphthalene formaldehyde) is added to the gypsum wallboard slurry to reduce the amount of water used, while maintaining the same slump as the slurry without dispersant. The lower water usage allows lower energy use to dry the wallboard, since less water is present in the wallboard
3）Oil drilling
Dispersants in oil drilling( ferrochrome lignosulphonate) are chemicals that aid in breaking up solids or liquids as fine particles or droplets into another medium. This term is often applied incorrectly to clay deflocculants. Clay dispersants prevent formation of "fish-eye" globules. For dispersing (emulsification) of oil into water (or water into oils), surfactants selected on the basis of Hydrophilic-lipophilic balance (HLB) number can be used. For foam drilling fluids, synthetic detergents and soaps are used, along with polymers, to disperse foam bubbles into the air or gas
4）Detergents
Dispersing agents are the principal applications of detergents for which the liquid bath is water. Detergents also are used as emulsifiers in many applications.
