Gypsum retarders are divided into proteins and modified amino acids according to chemical components. Among them, protein gypsum retarder has the characteristics of good retarding effect, small dosage and strong alkali resistance.
·Odorless, excellent retarding effect and low content;
·Good adaptability and good adaptability to all kinds of gypsum;
·The powder has good fluidity, not easy to absorb moisture, caking and good storage stability;
·With the increase of retarder content, the setting time of gypsum increases linearly, which is conducive to the quality stability of gypsum products.
