China Factory Supply Gypsum Retarder
This product is a kind of retarder for powdery and efficient protein gypsum-based building materials.This product is especially suitable for the following application fields:● Additives in the production of gypsum board, fiberboard, partition board, ceiling and gypsum block.● Additives for dry gypsum-based products such as caulking gypsum and plastering gypsum can effectively prolong the setting time of the above products.

Application characteristics
● Reduce the solubility of gypsum hemihydrate.
● Slow down the dissolution rate of gypsum hemihydrate.
● Retarding ions are adsorbed on the surface of gypsum dihydrate crystal, and these ions are
● combined into the crystal lattice.
● forming a complex to limit the diffusion of ions to the vicinity of gypsum dihydrate crystals.
Performance advantage
●Very effective retarding, at an already very low addition;
● Allow the setting time of the binder slurry to be adjusted to the needs in the manufacturing process;
● Increase the processing time of calcium sulfate-based materials by several hours, depending on the addition amount;Compatible with a variety of calcium sulfate binders and other additives;
● It does not reduce the later strength of gypsum products (unlike citric acid).
