The amino acid gypsum retarder determines the quality of plastering gypsum.
In modern interior wall decoration and leveling projects, plastering gypsum (including interior wall plastering gypsum) has become the mainstream alternative material to traditional cement mortar due to its convenient construction and green environmental benefits. However, problems such as rapid gypsum body setting, short operation window period, easy cracking when applied to the wall, and powder shedding and sanding have long plagued the construction team. The amino acid gypsum retarder, as a new generation of gypsum retarder additive, with its outstanding comprehensive performance, has become the core element determining the quality of high-quality plastering gypsum, redefining the quality standards of gypsum building materials.
Core advantages: Technological breakthrough and all-round performance upgrade
- Precise timing + Crystal protection, zero loss in strength
The amino groups, carboxyl groups and other functional groups in amino acid molecules can precisely adsorb on the surface of half-water gypsum particles and form complexes with calcium ions. Through “dual action”, they inhibit the rapid growth of dihydrate gypsum crystals, delay the water process at the same time, and perfectly protect the crystal structure of gypsum, promoting the development of larger and denser crystals. This characteristic not only enables the operability time of gypsum slurry to be linearly controllable, effectively solving the problem of rapid drying at high temperatures, but also ensures that the compressive and flexural strength of the hardened body has almost no loss, fundamentally avoiding the risks of insufficient gypsum strength, powder shedding and sanding.
- Wide adaptability + Construction-friendly, efficiency doubled
This product has excellent water solubility, low dosage and strong batch stability. It is compatible with various admixtures such as cellulose ethers, defoamers, water reducers, and self-dispersible latex powder, without component antagonism or sedimentation and stratification problems. It is suitable for all seasons and all construction scenarios. At the same time, its excellent water retention and rheological properties make the plastering gypsum apply more smoothly, easier to level, and easier to repair, significantly reducing the difficulty of mechanized spraying and manual application. Vertical wall construction without sagging and flowing, easy to finish and smooth. After construction, the wall is dense and fine, with high flatness, eliminating local drying cracks and unevenness caused by joints, and easily meeting the high standards of fine decoration in home improvement and large-scale industrial projects.
- Green and environmentally friendly + Multi-scenario adaptability, in line with industry trends
The raw materials of amino acid gypsum retarder come from natural amino acids or biological synthesis technology, without toxicity, odor, or irritating smell, does not release volatile organic compounds (VOC), and has good biodegradability, which is in line with the green and low-carbon development trend of the construction industry. At the same time, it has excellent resistance to high temperatures, alkalis, and weathering, and can still stably exert retardation effects in high-temperature construction environments, ensuring sufficient construction time without reduction, and comprehensively improving the problems of crack resistance and adjustable operability time of plastering gypsum.
Core product parameters and value
As a new generation of high-performance amino acid gypsum retarder (also known as gypsum crystal protection agent), its core characteristics are as follows:
Key performance: Low dosage, linearly controllable retardation effect, strong batch stability;
Core value: While extending the operability time, almost zero loss in compressive / flexural strength, solving the problem of no powder shedding in the formula of gypsum;
Applicable scenarios: Suitable for interior wall plastering gypsum and various plastering gypsum, effectively improving problems such as cracking when applied to the wall, powder shedding and sanding, insufficient strength;
Compatibility: Perfectly compatible with various cellulose ethers, water reducers, etc., without weakening the water retention, leveling and adhesion of the material.
Summary: The final quality of plastering gypsum depends not only on the purity of gypsum powder, but also on the scientific proportion of the core additive. The amino acid gypsum retarder with precise timing ability, excellent strength retention rate, green and environmentally friendly characteristics, and comprehensive optimization of construction performance has become the ideal core additive to improve the construction efficiency and quality of gypsum building materials, providing a more high-quality, environmentally friendly and efficient internal wall decoration solution for the construction industry.
