The main components of gypsum retarder can include a variety of organic and inorganic substances, such as sodium citrate, tartaric acid and so on. By reacting with dissolved components in gypsum, these substances delay the hydration reaction rate of gypsum, thus delaying the initial and final coagulation time. This delay does not affect the final strength of the plaster, ensuring the durability and stability of the finished product.

In recent years, with the improvement of building technology and construction standards, the demand for gypsum retarder continues to grow. New environmentally friendly gypsum retardants are gradually favored by the market, and they use more green and sustainable formulations to reduce the negative impact on the environment. Manufacturers are focusing on the development of efficient and environmentally friendly retarders to meet the sustainable development needs of the modern construction industry.
Adhesive mortars are one of the primary applications of HPMC, wherein a specific dosage of hydroxypropyl methylcellulose, typically ranging from 1.5 to 2.5 kg per ton, is incorporated into the mixture to achieve optimal performance. This mortars are mechanically blended with cement, quartz sand, and polymer binders combined with various additives to create a reliable adhesive for bonding insulation boards. Known as polymer insulation board adhesive mortar, it is formulated using high-quality modified special cements and various high-molecular weight materials that provide superior water retention and exceptional bonding strength. This adhesive type is crucial in the construction industry, especially in ensuring energy efficiency and thermal performance in buildings by effectively adhering insulation materials to the substrate.
Gypsum retarder is an important construction additive, designed to extend the setting time of gypsum materials, thereby improving the operability of construction. This chemical is widely used in the construction industry, especially in projects requiring a long construction time, and plays a vital role. Due to the short setting time of traditional gypsum, it limits the large-scale and complex construction process, and after the addition of retarder, workers can more easily carry out fine construction and adjustment, ensuring the construction quality and efficiency.
