Naphthalene sulfonate formaldehyde condensates sodium salts applied for concrete admixtures,the dosage is recommended 0.5%-1.2%(Powder),and for 40% liquid,the suggested dosage is 1.2%-2.8%.
But it is a data that we suggest,we strong our users to do a trial before use it in bulk to determine the dosage according to definite conditions.For example,when change a new brand of cement.

Naphthalene sulfonate formaldehyde condensates sodium salts is synthesized from crude naphthalene,sulfuric acid,formaldehyde and caustic soda etc.So Naphthalene sulfonate formaldehyde powder price is influenced by these raw materials prices.And the main cost of these raw materials is crude naphthalene cost.In China market,crude naphthalene is made from coking industry,So price of crude naphthalene fluctuates,and result price of naphthalene sulfonate formaldehyde powder always not stable,fluct...

Naphthalene sulfonate formaldehyde powder is mainly packed in 25kg/bag PP bag with PE bag liner inner.Or 25kg/bag,kraft paper bag with waterproof PE bag liner inner. Or packed in Jambo bag,600kg/jambo bag or 720kg/jambo bag.
Loading in container:
For 25kg/bag,without pallet,15mt/20',26mt/40'
      25kg/bag,with pallet,13mt/20',26mt/40' ,1300kg/pallet.
      600kg/jambo bag,12mt/20', 24mt/40' with  pallets.
      720kg/jambo bag,14.4mt/20', 25.92mt/40' with pallets.

Normally,Original form of Naphthalene sulfonate formaldehyde condensate sodium salts is liquid form,40% solid content,and it can be applied to concrete directly.
Because Naphthalene sulfonate formaldehyde condensate sodium salts users are located far from Naphthalene sulfonate formaldehyde condensate sodium salts factory,liquid form packed in drum or tank,it will result the packing fee expensive and increase transportation cost to a not small extent.So Naphthalene sulfonate formaldehyde conden...

Chloride(Cl ion) in naphthalene sulfonate formaldehyde condensates sodium salts mainly come from caustic soda, which is a raw material of naphthalene sulfonate formaldehyde condensates sodium salts synthesis.Because caustic soda is made from sodium chloride.
There are two main production processes for caustic soda made from sodium chloride:ionic membrane method and isolating membrane method.Chloride contained in caustic soda that made by isolating membrane method is higher than that caustic so...

Naphthalene sulfonate formaldehyde condensates sodium salts is mainly used for concrete admixtures.In China,naphthalene sulfonate formaldehyde condensates sodium salts is classified AS CONCRETE ADMIXTURES,HIGH RANGE WATER REDUCER,The HS CODE is 3824401000.
But in fact,Naphthalene sulfonate formaldehyde condensates sodium salts also can be used for pigment dispersing agent,and the HS CODE is not 3824401000,its HS CODE is 3809910000.

Naphthalene sulfonate formaldehyde sodium salts is synthesized from raw materials,crude naphthalene,sulfuric acid,formaldehyde and caustic soda,etc.

So naphthalene sulfonate formaldehyde sodium salts contains sodium sulfate.

Sodium sulfate has a feature:when working temperatures drops to below 5 ℃,sodium sulfate will crystallize,it oftern happens in winter especially in cold region.the sodium sulfate crystals will has a negative effect to concrete performance.SO try to remove this crystal...
