Sodium Naphthalene Sulphonate
Yangs & M Enterprise Limited
Product Name:Sodium Naphthalene Sulphonate
Molecular weight:472.44
Molecular Formula:
C21H14Na2O6S2
Detailed Introduction
Molecular formula: C21H14Na2O6S2
Molecular weight: 472.44
Executive standard: GB/T8077-2012
Packing: 25KGS PP/PE bags or custom demand
Uses: 1. Widely used in precast & ready-mixed concrete, armored concrete and pre-stressed reinforced concrete in key construction projects such as dam and port construction, road building & town planning projects and dwelling erections etc.
2. Suitable for preparation of early-strength, high-strength, high-anti-filtration and self sealing&pumpable concrete.
3. Used for and widely for self-cured, vapor-cured concrete and its formulations. At the early stage of application, extremely prominent effects are shown. As the result, the modulus and site utilization can be drastically, the procedure of vapor cure is omitted in peak heat summer days. Statistically 40-60 metric tons of coal will be preserved when a metric ton of the material is consumed.
4. Compatible with Portland cement, normal Portland cement, Portland slag cement, flyash cement and Portland pozzolanic cement etc.
Features:
Kept in dry and ventilating place, prevent from rain and moisture when storage, if agglomerated, please crush and make it into solution, and its effect will be the same.
