Naphthalene Water Reducing Agent Plays an Important Role in Plasterboard Production
The water-reducing agent is an additive that can keep the working fluidity of gypsum slurry unchanged and significantly reduce the added amount. Adding water-reducing agents in the production of gypsum board, even in the case of a lower water-to-slurry ratio, can still improve the proper fluidity of gypsum slurry. Therefore, reducing the amount of process-forming water added. During gypsum board drying, the amount of evaporated water is correspondingly reduced, reducing the energy consumption of drying gypsum board and the production cost. Water-reducing agents are mostly surface-active substances. Anionic water reducers include sodium naphthalene sulfonate formaldehyde condensate salts. Sodium naphthalene sulfonate formaldehyde water-reducing agent is a slightly yellow powder, easily soluble in water. It is prepared by sulfonating naphthalene, condensing it with formaldehyde, and then neutralizing it. It has a good water-reducing and strengthening effect on gypsum slurry. Sodium naphthalene sulfonate formaldehyde water-reducing agent, the amount added to the plasterboard slurry is about 0.2% of the mass of plaster, reducing the amount of water added by 5%~10% and increasing the strength of gypsum board by 5%~ 10%. Concrete water-reducing agents are admixtures that perform a specific role in concrete.
To begin with, a concrete water-reducing agent reduces the "unit amount" of water used while mixing concrete without impacting the concrete's workability to lower the cement-water ratio, improving the concrete's strength. Secondly, a water-reducing agent does not lower the mix performance of the concrete (other than the unit water consumption) and can dramatically alter the mix-compound workability of the concrete, lower the consumption of construction energy, and facilitates easier construction.
