CF210Naphthalene Moderate Temperature Cement Dispersant
The CF210naphthalene moderate temperature cement dispersant includes CF210L liquid andCF210S powder. The cement dispersant in the form of russet liquid is composedof 30% polynaphthalene alkyl sulfonateand 70% water coming with the CAS number of 7732-18-5. While the cement dispersant in the form ofbrownish yellow powder only contains 98% polynaphthalenealkyl sulfonate.
Generally speaking, thedosage of CF210S naphthalene moderate temperature cement dispersant is 0.4-1.5%by weight of cement, with a recommended amount of 0.5% BWOC. In addition, thedosage for CF210L naphthalene moderate temperature cement dispersant isgenerally 0.8-4.0% BWOC, and the recommended amount is 1.5% by weight of cement.
With 1.15±0.05g/cm3 relative density, the CF210L naphthalene moderatetemperature cement dispersant is completely soluble in water. It has a pH valueranging from 5.0 to 7.0, so this liquid dispersant used in cement is acidic. In addition, the CF210L cement dispersantwith slightly pungent odor can be frozen at -2℃. The CF210S naphthalene moderate temperature cement dispersant is a powder with thegranularity of more than 100 meshes. When completely dissolved in the 5%aqueous solution, the pH value of this cement dispersant is within the rangebetween 5.0 and 7.0. With a bulk density of 0.55±0.10g/cm3, it is suitable fordry mixed and water mixed use.
