萘磺酸钠甲醛缩合物

Sodium naphthalene sulfonate formaldehyde is one of High Range Water-Reducing Admixture. Main Performance: Sodium Naphthalene Formaldehyde produces concrete with extremely workable characteristics referred to as high slump. Sodium naphthalene formaldehyde 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 other 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 Sodium Naphthalene Formaldehyde can be added directly or added in after dissolved. 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 Direction: Direct use of powdery agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio: 60%). It is a good water reducer, and concrete admixture.
