Gypsum retarder is a chemical additive used to delay the setting and hardening process of gypsum materials. This additive achieves the purpose of extending the hardening time of gypsum by changing the crystallization rate and reaction kinetics of gypsum.
1. Why is retarding needed:
Construction requirements: In some construction scenarios, such as large-area gypsum plastering or sculpture making, longer operation time is required to ensure the uniformity and accuracy of construction quality. The use of retarders can provide more operation time for construction workers and reduce construction quality problems caused by time pressure.
Material performance optimization: The use of retarders can not only extend the hardening time of gypsum, but also improve certain properties of gypsum materials, such as reducing shrinkage and improving crack resistance.
Which fields need retarding:
Construction industry: In occasions such as plastering of internal and external walls of buildings, ground leveling, and decorative line making, retarders are needed to extend the hardening time of gypsum and ensure construction quality and efficiency.
Sculpture and model making: In the process of sculpture and model making, fine carving and polishing are required, and retarders can provide artists and designers with more time to perfect their works.
Industrial application: In some industrial fields, such as mold making and gypsum board production, retarders are also needed to control the hardening time of gypsum to meet specific production needs.
2. Coagulation:
In gypsum materials, coagulation refers to the process in which gypsum reacts with water to form hydration products (such as dihydrate gypsum). In this process, gypsum particles gradually dissolve and react chemically with water to form a dense crystal structure, so that the gypsum material gradually hardens and has strength. The role of the retarder is to delay the hardening time of gypsum by affecting this coagulation process. Specifically, the retarder can react with certain components in the gypsum to reduce the dissolution rate of gypsum particles or inhibit the formation of hydration products, thereby achieving a slow setting effect.
XY-SJ-N1, as an innovative protein-based gypsum retarder, has a significant retarding effect and broad application prospects in the gypsum industry. This retarder, with its unique molecular structure and retarding mechanism, provides more accurate and efficient setting time control for gypsum materials.

Molecular structure characteristics:
The molecular structure of XY-SJ-N1 has been carefully designed and has high specificity and stability. Its unique protein structure enables it to play an excellent retarding role in the hydration process of gypsum. Compared with traditional gypsum retarders, the molecular structure of XY-SJ-N1 is more refined and can act more accurately on the setting process of gypsum.
Retarding mechanism:
The retarding mechanism of XY-SJ-N1 is mainly to interact with certain components in gypsum through its special molecular structure, thereby changing the setting dynamics of gypsum. Specifically, XY-SJ-N1 can combine with calcium ions and sulfate ions in gypsum to form a stable complex, reducing the dissolution rate of gypsum particles and the formation rate of hydration products. This mechanism of action prolongs the setting process of gypsum, thus giving it the required setting time.
High efficiency at low dosage:
It is worth mentioning that XY-SJ-N1 can play a significant retarding effect at low dosage. This is mainly due to its special molecular structure and retarding mechanism. Since the molecular structure of XY-SJ-N1 has high activity and stability, it can effectively act on the setting process of gypsum even at low dosage. This low dosage and high efficiency make XY-SJ-N1 more economical, environmentally friendly and efficient in practical applications.
XY-SJ-N1 new protein gypsum retarder is widely used in architecture, sculpture, mold making and other fields. In the construction industry, it can be used for internal and external wall plastering, ground leveling, decorative line making and other occasions, providing construction workers with more operating time to ensure construction quality and efficiency. In the field of sculpture and model making, XY-SJ-N1 can provide artists and designers with more time to perfect their works and improve the fineness and quality of their works. In addition, XY-SJ-N1 can also be used in gypsum board production, mold making and other processes in the industrial field to meet the needs of different industries for the setting time of gypsum materials.
