SODIUM NAPHTHALENE SULPHONATE FORMALDEHYDE CONDENSATE POWDER
INTORDUCTION:
CAS Code: *********7
HS Code (CN): *******0
SNF a high range water reducer, commonly referred to as a super
plasticizer, also named Naphthalene Sulphonate Formaldehyde
Condensate (short name: SNF, PNS, NSF, etc…)
SNF is made from naphthalene, sulfuric acid, formaldehyde and
liquid alkali, through sulfonation, hydrolyzation, condensation and
neutralization reaction and then drying to powder. SNF-A5% contains
very small chloride. Thus, it meets the requirements of chemical
admixture specifications for concrete: ASTM Designation C **4 as a
Type F admixture, GB********8 and GB*********3.
Uses
SNF produces concrete with extremely workable characteristics
referred to as high slump.
SNF also allows concrete to be produced with very low water/cement
ratios at low or normal slumps.
SNF is ideal for use in pre stress, precast, bridge deck or any
concrete where it is desired to keep the water/cement ratio to a
minimum and still achieve the degree of workability necessary to
provide easy placement and consolidation.
SNF will also fluidize concrete, making it ideal for tremie
concreting or other applications where high slumps are desired.
SNF is compatible with Portland Cement, Normal Portland cement,
Portland Slag Cement, Fly-ash Cement, Portland Pozzolanic Cement,
etc.
Advantages
SNF produces high slump flowable concrete with no loss in
strength.
SNF produces low water/cement ratio concrete and therefore, high
strengths.
SNF in prestress/precast work, can be used to substantially reduce
or eliminate the high energy requirements of external heat for
accelerated curing.
SNF concrete, even at high slump, exhibits no significant
segregation in comparison to concrete without a super-plasticizer
at the same slump.
SNF aids in rapid discharge of concrete from truck mixers thereby
reducing on the job time and improving mixer utilization.
Properties, Features & Characteristics
Visual Appearance: Light brown powder. Non-poisonous, odorless,
non-flammable and non-corrosive to steel bars.
Remarkable Plasticity: As a condition of blending where amount of
cement and collapsibility are fixed aforehand, mixing water can be
decreased by ****0% when it is mixed with reinforced concrete at
0.**1.5%.
Improve miscibility of concrete amalgamator with water and
collapsibility as well. As a condition of equivalent blending,
collapsibility can be increased.
