Gypsum Retarder is a very professional chemical preparation with good adsorption performance, chemical performance and precipitation performance. By adding an appropriate amount, it can make gypsum mortar, plastering gypsum, bonding gypsum, caulking gypsum and other gypsum products. Obtain an effective setting delay, thus creating better conditions for construction.
About the performance of gypsum retarder
1. Physical properties: fine powder, slightly yellowish, non-toxic radioactive elements, non-flammable and explosive, slightly alkaline
2. Setting time: It can delay the initial and final setting time of building gypsum by more than 100 minutes. The retarding time is prolonged with the dosage, and the optimum dosage is 1-3‰
3. Compatibility: The product does not contain additives such as chloride salts and water-retaining agents, and has good compatibility.
4. PH value: (20℃, 20% solution) PH value is 7-9.
5. This product has strong applicability and can be mixed with natural gypsum and chemical gypsum.
6. This product should be protected from moisture to avoid agglomeration.
How to use gypsum retarder
1. Mix the retarder and gypsum powder evenly or completely dissolve in water, then add the gypsum powder;
2. If the initial setting time is long, it is necessary to increase the amount of retarder, otherwise, reduce the amount of retarder;
3. If the proportion of gypsum powder is large, it needs to increase the amount of retarder, otherwise, reduce the amount of retarder;
4. If the operation time is long, the retarder needs to be added, otherwise, the retarder should be reduced;
Yida can formulate the optimal application method of retarder according to your gypsum powder products.
Application fields of gypsum retarder
Gypsum retarder is widely used in gypsum mortar, plastering gypsum, bonding gypsum, caulking gypsum, gypsum block, ceramic model, gypsum powder for gypsum board and other systems.
Precautions when using gypsum retarder.
