Gypsum setting retartding agent
一、 Description
High efficient gypsum setting retarding agent is developed by our company. Its mixing amount is small and the setting retarding effect is good. The sitting time of the gypsum can be controlled well by this agent. Using this agent, the strength loss of the hardened gypsum is very small. This product is suitable for the plaster gypsum, the glue gypsum, the prefabricated gypsum components, the gypsum stuffing materials. the gypsum model broad, the gypsum decoration coating , and so on , Because the fluidity of this powder is very good , it can be mixed wall with the gypsum, whether it is mixed by the spiral mixing or by the grinding
. According to the requirement, the operable time of the plaster gypsum and the glue gypsum can be prolonged for one to several hours by using this product. This will make things convenient for the construction, increase the efficient and reduce the cost. coordinating to use with our company ’ s SM high efficient water reducer, the setting time and the thickness of the gypsum paste can be controlled as you want . This product provides the convenient condition for developing and using the gypsum resources, promoting the application range of the gypsum, and raising the construction pace.
二、 Properteis
