SODIUM NAPHTHALENE SULPHONAT SNF-A,B,C
SNF-A HIGH-EFFICIENCY SUPERPLASTICIZER
(I)PROPERTIES,FEATURES&CHARACTERISTICS(FDN-A)
1. Appearance:Light brown powder&dark brown liquid. Non-poisonous,odorless,non-flammable and non-corrosive to steel bars.
2. Remarkable Plasticity:As a condition of blending where amount of cement and collapsibility are fixed aforehand,mixing water can be decreased by 18-28%when it is admixed with reinforced concrete at 0.5-1.0%. Statistically,compression strength on the 1st day,the 3rd day and the 28th day after single application is increased by 60-90% and 25-60% respectively when it is added at standard blend dosage.As the result,compression strength,tensile strength,buckling strength and modulus of elasticity will be improved to some extent.
3. Improve miscibility of concrete amalgamator with water and collapsibility as well.As a condition of equivalent blending,collapsibility can be increased 5-8 times when it is added at 0.75% blend dosage.
4. 15-20% of cement can be reserved when the agent is blended at 0.75% blend dosage,which is precondition by same collapsibility and strength.

SNF-B HIGH-EFFICIENCY SUPERPLASTICIZER
(I)PROPERTIES,FEATURES&CHARACTERISTICS(SNF-B)
- Appearance:
Light brown powder&dark brown liquid. Non-poisonous,odorless,non-flammable and non-corrosive to steel bars.
- Remarkable Plasticity:As a condition of blending where amount of cement and collapsibility are fixed aforehand,mixing water can be decreased by 17-25%when it is admixed with reinforced concrete at 0.5-1.0%. Statistically,compression strength on the 1st day,the 3rd day and the 28th day after single application is increased by 60-95% and 25-50% respectively when it is added at standard blend dosage.As the result,compression strength,tensile strength,buckling strength and madulus of elasticity will be improved to some extent.
- Improve miscibility of concrete amalgamator with water and collapsibility as well.As a condition of equivalent blending,collapsibility can be increased 4-7 times when it is added at 0.75% blend dosage.
- 15-18% of cement can be reserved when the agent is blended at 0.75% blend
dosage,which is precondition by same collapsibility and strength.

SNF-C HIGH-EFFICIENCY SUPERPLASTICIZER
(I)PROPERTIES,FEATURES&CHARACTERISTICS(SNF-C)
- Appearance:
Light brown powder&dark brown liquid. Non-poisonous,odorless,non-flammable and non-corrosive to steel bars.
6.Remarkable Plasticity:As a condition of blending where amount of cement and collapsibility are fixed aforehand,mixing water can be decreased by 16-22%when it is admixed with reinforced concrete at 0.5-1.0%. Statistically,compression strength on the 1st day,the 3rd day and the 28th day after single application is increased by 60-95% and 25-40% respectively when it is added at standard blend dosage.As the result,compression strength,tensile strength,buckling strength and madulus of elasticity will be improved to some extent.
7.Improve miscibility of concrete amalgamator with water and collapsibility as well.As a condition of equivalent blending,collapsibility can be increased 4-6 times when it is added at 0.75% blend dosage.
8.15-18% of cement can be reserved when the agent is blended at 0.75% blend dosage,which is precondition by same collapsibility and strength.

(IV)USAGE:
1.Blending dosage at 0.5-1%,0.75%mixing dosage advised. 2.Prepare solutions as
required.
3.Direct use of powder agent is allowed.Altematively the addition of the agent isfollowed by water moisturization(water-cement ratio:60%)
4.The agent can be combined with other extemally applied agents if pilot development or laboratory experiment succeeds.
(V)PACKING,STORAGE AND TRANSPORTATION
1.package:
Powder: packing in Woven fabric bag with plastic inner.Net weight:25kg±0.2kg or 650kg±0.2kg
2.Cautions:
Prevented from being tom by sharp-ended objects while packages are being transferred or delivered. When being contaminated by high humidity or moisture in case of leakage,it can be prepared in prescribed ways for further use without surrendering any effect.
3.It should be stored in a dedicated warehouse that is well-ventilated and dry.If be affected with damp,just smash or melt it into solution without any bad effection.
