Gypsum Retarder is a very professional chemical agent with good adsorption, chemical and precipitation properties. With proper addition, it can make gypsum mortar, stucco gypsum, bonding gypsum, caulking gypsum and other gypsum products Obtain effective setting delay, thereby creating better conditions for construction.
|Physical properties||fine powder, slightly yellowish, non-toxic radioactive elements, non-flammable and explosive, slightly alkaline|
|Setting time||It can delay the initial and final setting time of building gypsum by more than 100 minutes. The retardation time is prolonged with its dosage, and the best dosage is 1-3‰|
|Compatibility||The product does not contain additives such as chlorine salt and water retaining agent, and has good compatibility|
|PH value||(20ºC, 20% solution) PH value is 7-9|
|This product has strong applicability and can be mixed and used in natural gypsum and chemical gypsum|
|This product should be protected from moisture to avoid agglomeration|
Gypsum retarders are widely used in systems such as gypsum mortar, stucco gypsum, bonding gypsum, caulking gypsum, gypsum blocks, ceramic models, and gypsum powder for gypsum board
The recommended dosage of this product is 0.5-3‰ of the system, and the dosage needs to be determined by experiment
(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.
(5) Yida can formulate the best retarder use method according to your gypsum powder product
