Sodium naphthalene formaldehyde produces concrete with extremely workable characteristics referred to as high slump. Pns also allows concrete to be produced with very low water/cement ratios at low or normal slumps.Sodium naphthalene formaldehyde is ideal for use in prestress, 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.
Addition ratessodium naphthalene formaldehyde can be added directly or added in after melt. It can be added during mixing and after-mixing. The afterward approach can achieve better result. The suggested addition rate is 0.75%.Sodium naphthalene formaldehyde directionprepare solutions as required.Direct use of powdery agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio: 60%).The agent can be combined with other externally applied agents if pilot development or laboratory experiment succeeds.
Packed in plastic film bag wrapped with plastic woven sack with a net weight of 25kg each.
Sodium Naphthalene Formaldehyde (SNF-Superplasticizer for Concrete) CAS Code: 36290-04-7 SNF a high range water reducer, commonly referred to as a super plasticizer, also named Naphthalene Sulphonate Formaldehyde Condensate (short name: SNF, PNS, NSF, etcâ?¦) 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 494 as a Type F admixture, GB8076-2008 and GB50119-2003. Usage 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.

Yl-sg Sodium Gluconate Set Retarder (industrial grade & food grade) YL-SG is a set-retarding admixture, and it can slow down the hydration of cement, prolong setting time, and extend the working life of concrete for long periods without any negative influence on the concrete quality. Performance: * Extend concrete initial setting time during hot weather. * Increasethe workable time of concrete up to several hours. * Provideflexibility in planning and scheduling of concrete pours. * Applicable for massive concrete, precast concrete and large area construction.
Description YL-SG is a kind of sodium polyhydroxy carboxylate. Its appearance is white or light yellow crystal powder. It is easily soluble in water, slightly soluble in alcohol, and insoluble in ether. It can be used as a retarder in concrete industry, or chelating agent in textile dyeing, metal surface treatment and water treatment industries, as steel surface cleaning agent, or glass bottle detergent. Performance Used as a cement additive: it can slow down the hydration of cement, prolong the setting time and extend the service life of concrete, no negative effect on quality of concrete in hot weather; Used as steel surface cleaning agent; Used as a special detergent for glass bottles; Other industrial fields such as electroplating, film manufacturing, etc.
