Gypsum retarder is a gray-white powder, soluble in water, mainly by adding in gypsum to increase the use of gypsum, delay the solidification time. Just add a small amount. Mainly used in plaster, glue plaster (to enhance the bonding effect) , plaster putty (to make the surface more smooth and smooth) , plaster filler and plaster model.
The gypsum retarder is packed in paper-plastic bags lined with polyethylene plastic bags. The weight of each bag is about 25KG/bag. Gypsum retarder should be kept in a cool dry place, because gypsum retarders are powder, easy moisture absorption, so need to be stored in a sealed bag, temperature should not exceed 40 degrees Celsius to maintain stability.
Gypsum retarder content is small, so there are the following characteristics: First: extend the effect of good solidification, solidification time can adjust the second product powder fluidity is good, easy to fully mix with gypsum. Finally, after the gypsum retarder is used, the operation time of plastering and bonding mortar can be extended by one hour according to the need
Because the gypsum retarder can significantly extend the gypsum, mortar, and so on the use of time. It not only provides sufficient operating time for construction personnel, but also achieves the goal of reducing cost successfully, and brings higher economic benefits for engineering projects. In a word, gypsum retarder is an important contributor to building engineering with high quality.
