Methoxypropyl Methyl Cellulose (HPMC), a derivative of cellulose, is an essential ingredient in various industries due to its unique properties and versatility. HPMC is formed by the chemical modification of cellulose, a natural polymer found abundantly in plant cell walls, through the substitution of hydroxyl groups with methoxy and propoxyl groups. The resulting product, HPMC, carries the chemical formula (C6H7O2(OCH3))(OCH2CH3)x, where 'x' represents the degree of substitution.

- The process of manufacturing cellulose often begins with the harvesting of plants such as cotton, wood, hemp, or flax. These raw materials undergo a series of treatments to extract the cellulose fibers. The extraction process involves mechanical and chemical treatments that remove other components such as lignin and pectin, leaving behind pure cellulose.

Thermal stability of HPMC and MHEC is affected by their gel temperature. In general, the gel temperature of HPMC is around 60℃-75℃ depending on its group content and different production technique. Due to the characteristics of MHEC group, it has a higher gel temperature, usually > 80℃. Therefore its stability under high temperature is better that HPMC. On the other hand, because there are more hydrophilic groups in the structure of MHEC, it has better hydrophilicity. The water retention rate of MHEC in mortar is a little higher than HPMC at the same dosage of products with the same viscosity.

- Methyl cellulose (MC) and hydroxypropyl methylcellulose (HPMC) are versatile polymers commonly used in drug delivery systems due to their ability to form hydrogels, control drug release, and enhance the stability of various formulations. These polymers are hydrophilic, biocompatible, and non-toxic, making them suitable for a wide range of applications in pharmaceuticals.
- Furthermore, Methocellose HPMC finds use in the paint and coatings industry, where it improves the flow and leveling properties of paints, reduces brush marks, and enhances the overall finish. It also aids in the retention of pigments, making it an ideal additive.
- One of the key advantages of RDP is its ability to maintain its physical and chemical properties even after being redispersed. This means that it can be used in a variety of products without losing its effectiveness. For instance, in the construction industry, RDP can be used as an additive in cementitious systems to improve workability, reduce water demand, and enhance strength. In the paint and coating industry, it can be used to create water-based coatings with excellent film formation and durability.

In the specific construction, the water retention effect of the slurry can be adjusted by increasing or decreasing the amount of HPMC added. The water retention of hydroxypropyl methyl cellulose ether under high temperature conditions is an important indicator to distinguish the quality of hydroxypropyl methyl cellulose ether. Excellent HPMC series products can effectively solve the problem of water retention at high temperatures.
In high temperature seasons, especially in hot and dry areas and thin-layer construction on the sunny side, high-quality HPMC is required to improve the water retention of the slurry. High-quality HPMC has very good uniformity. Its methoxy and hydroxypropoxy groups are evenly distributed along the cellulose molecular chain, which can improve the ability of the oxygen atoms on the hydroxyl and ether bonds to associate with water to form hydrogen bonds , So that the free water becomes bound water, thereby effectively controlling the evaporation of water caused by high temperature weather, and achieving high water retention.
High-quality cellulose HPMC can be uniformly and effectively dispersed in cement mortar and gypsum-based products, and wrap all solid particles, and form a wetting film. The water in the base is gradually released over a long period of time. The condensed material undergoes hydration reaction to ensure the bonding strength and compressive strength of the material. Therefore, in high-temperature summer construction, in order to achieve the effect of water retention, high-quality HPMC products must be added in sufficient quantities according to the formula, otherwise, insufficient hydration, reduced strength, cracking, hollowing and falling off caused by excessive drying will occur. It also increases the difficulty of construction for workers. As the temperature decreases, the amount of HPMC added can be gradually reduced, and the same water retention effect can be achieved.- تايلهاي کراميک متصل شده
