sodium naphthalene sulfonate formaldehyde condensate

الوصف

superplasticizer, Its appearance is Dark brown powder; Non-poisonous, odorless, non-flammable and non-corrosive.
This super plasticizer is naphthalene based superplasticizer, it is compound of naphthalene sulfonate formaldehyde condensates sodium salts.  It is an additive that increases the plasticity and fluidity of  concrete to which it is added.It can soften the concrete before it hardens,increase concretes workability,reduces water,and not affect the properties of the final concrete structures projects,but improve the strength of concrete. SNF superplasticizer can be applied to make flowable, strong or steam-curing concrete. The minimum working temperature can be as low as 0 C. In steam curing, concrete with superplasticizer has to strong enough before heating. SNF NSFcan reduce water more than *5%. It has features of superplasticizer, effectively increases concrete fluidity and reduces water penetration and segregation. Therefore, improves concrete placement and makes concrete easy to use and compacting.Strengthening: Given the same amount of cement and slump requirement, this product can increase the concrete stress by *****0%, ****0%, ****0% and ****0% on day 1, 3, 7, and *8 respectively.Sodium Naphthalene Formaldehyde Specification:
