The recommended dosage of this product is 0.5-3‰ of the system, and the dosage needs to be determined by experiment
Instructions
(1) The selected amount of retarder must be uniformly mixed with gypsum powder or the retarder must be completely dissolved in water before adding gypsum powder
(2) The amount of gypsum retarder added is determined according to the initial setting time of the gypsum powder. If the initial setting time is long, the amount of retarder needs to be added, otherwise, the amount of retarder is reduced.
(3) The amount of gypsum retarder added is determined according to the proportion of gypsum powder in the gypsum mortar. If the proportion of gypsum powder is large, the amount of retarder needs to be added, otherwise, the amount of retarder is reduced.
(4) The amount of gypsum retarder added is determined according to the operating time required for the gypsum mortar. If the operating time is long, the amount of retarder needs to be added, otherwise, the amount of retarder is reduced.
