3. Construction Industry In construction, HPMC is utilized as an additive in cement, tile adhesives, and plaster. It enhances workability, improves adhesion properties, and contributes to the water retention of mortar and plaster, ensuring a better finish and durability of structures.

In addition to its functional properties, HPMC is also stable across a wide range of pH levels and temperatures, ensuring that products maintain their efficacy and quality over time. Its versatility allows manufacturers to tailor formulations to meet specific requirements, enhancing product performance.

If necessary, adjust the PH value of the solution after the dissolution of hydroxyethyl cellulose. However, please note that alkaline substances should not be added before the hydroxyethyl cellulose powder is soaked in water to avoid affecting the dissolution effect. Raising the PH value after soaking can help accelerate the dissolution rate.

Composition and Production

Polyvinyl acetate powders are versatile RDPs often used in woodworking adhesives and paper products. Known for their exceptional adhesion properties, PVA powders are especially effective in bonding porous substrates. They provide good moisture resistance, making them suitable for applications where humidity could be a concern. PVA is also appreciated for its compatibility with various fillers and additives, broadening its application potential.

Redispersible polymer powder also plays a crucial role in the formulation of adhesives and sealants. In these products, RDP enhances adhesion to various substrates, including porous and non-porous materials. It enables the formulation to maintain optimal workability while ensuring quick setting times. The improved elasticity and flexibility provide additional resistance to temperature fluctuations and moisture, making RDP an ideal choice for construction adhesives used in demanding environments.

Alkalization treatment: Place the pretreated cellulose into a reactor and add sodium hydroxide solution for alkalization treatment. This step aims to disrupt the crystal structure of cellulose, making it easier for subsequent etherification reactions.

In personal care products, HPMC acts as a thickener and stabilizer in lotions, creams, and shampoos, offering a smooth texture and a pleasant application experience. Its versatility serves to enhance product performance across various sectors.

In pharmaceutical applications, HPMC is commonly used as a binder in tablet formulations, a film-forming agent for coatings, and a controlled-release excipient. Its biocompatibility and ability to form stable gels make it suitable for use in drug delivery systems. In the food industry, HPMC acts as a thickener, stabilizer, and emulsifier, enhancing the texture and shelf life of products.
