Famous for its chemical property of dispersant and protection for colloidal.
Characteristics
Tamol NN 3501 has excellent diffusibility and protective colloid properties, but Tamol NN 3501 has no surface activity such as osmotic foaming, and has affinity for protein and polyamide fibers, but has no affinity for cotton, hemp and other fibers.
Uses
Tamol NN 3501 is mainly used as a dispersant in disperse dyes and vat dyes; Tamol NN 3501 can also be used as a dispersant in textile printing and dyeing, wettable pesticides,electroplating additives, water treatment agents, etc.
Advantages
Tamol NN 3501 has many advantages, including:
(1) High water reduction rate.
When the water-cement ratio is certain, the initial slump of concrete can be increased by more than 10cm, and the water reduction rate of polynaphthalene sulphonic acid can reach 15-25%.
What's more, when the strength and slump are basically the same, polynaphthalene sulfonate can also reduce the amount of cement by 10-25%.
(2) Good reinforcement.
Poly-naphthalene sulfonate-based high efficient water reducing agent has obvious early strength and enhancement effect on concrete, with strength enhancement range of 20-60%. (3)Strong adaptability.
Tamol NN 3501 is suitable for various specifications and models of cement.
And Tamol NN 3501 has good compatibility with other concrete admixtures.
(4) Good durability.
Tamol NN 3501 can effectively improve the pore structure of concrete, so as to improve the durability indexes of concrete such as impermeability, carbonation resistance and frost resistance.
(5) Improvement of concrete's ease of use.
Comprehensively improve the physical and mechanical properties of concrete.
(6) The application is wide.
Applicable to many concrete projects.
Such as fluid concrete, plasticised concrete, steam curing concrete, waterproof concrete, etc.
(7) High safety.
Tamol NN 3501 is a kind of harmless chemical with many characteristics such as non-toxic, non-irritant, non-radioactive and so on.
Tamol NN 3501 has no corrosive effect on steel reinforcement.
