Hydroxypropyl methylcellulose (HPMC) 02 I. Overview of hydroxypropyl methylcellulose (HPMC): Hydroxypropyl methylcellulose (HPMC) is a white powder or off-white powder. Mainly used in the construction industry, water-resistant putty powder, cement mortar, etc. The main technical indicators are: viscosity and water retention. Our company has mature production technology, advanced equipment, and stable quality. 2. Viscosity and quality standards of hydroxypropyl methylcellulose (HPMC): 3. Characteristics of hydroxypropyl methylcellulose (HPMC): 1. Properties: This hydroxypropyl methylcellulose is a white or slightly yellowish powder. 2. Water solubility and thickening ability: This instant hydroxypropyl methylcellulose water-soluble type can be dissolved in cold water to form a transparent viscous solution. 3. Solubility in organic solvents: Since it contains a certain amount of hydrophobic methoxy, this hydroxypropyl methylcellulose is soluble in some organic solvents, and can also be dissolved in solvents mixed with water and organic matter. 4. PH stability: The viscosity of this hydroxypropyl methylcellulose solution is stable in the range of PH3.0-10.0. After less than 3 or greater than 10, the viscosity will decrease greatly. 5. Surface activity: This aqueous hydroxypropyl methylcellulose solution has surface activity, making it emulsifying, protecting colloid and relative stability. 027. Low ash content: Since this hydroxypropyl methylcellulose is nonionic, it can be washed with hot water during the preparation process and is effectively refined, so its ash content is very low. 8. Salt resistance: Since this hydroxypropyl methylcellulose is a nonionic and non-polymerized electrolyte, it is relatively stable in aqueous solutions of metal salts or organic electrolytes. 9. Water retention: Due to the hydrophilicity of this hydroxypropyl methylcellulose and its aqueous solution are highly viscous. It is added to mortar, plaster, paint, etc., to maintain high water retention in products. 10. Mold resistance: It has relatively good mold resistance and good viscosity stability during long-term storage. 11. Lubricity: Adding this hydroxypropyl methyl cellulose is enough to reduce the friction coefficient and improve the lubricity of construction. 12. Film-forming property: This hydroxypropyl methyl cellulose produces strong, flexible, transparent flakes, and has good oil and ester resistance. 0202 IV. Hydroxypropyl methyl cellulose (HPMC) uses: 02 Hydroxypropyl methyl cellulose is widely used in water-resistant putty powder: it mainly improves the water retention performance of interior and exterior wall construction, improves its hydration and opening efficiency, makes the putty surface fully hardened and smooth, and the thickening effect improves its adhesion to the wall. Improved uniformity makes plastering easier to apply, while improving anti-drip, fluidity and pumpability. Thus, work efficiency is improved. High water retention, extending the working time of the mortar, and high mechanical strength during solidification. Hydroxypropyl methyl cellulose is used in cement mortar: significantly improves its bonding strength, makes the mortar better bonded to the bottom surface, intact water retention, retarding performance, improved strength, and has anti-sagging, anti-sagging and anti-dripping properties. The high viscosity products produced by our company are particularly suitable for polyphenylene granule insulation mortar applications. Hydroxypropyl methylcellulose is used in construction glue: The cold water instant high-viscosity product produced by our company has good dispersion and high viscosity in cold water. The gel time can be customized according to customer needs, and does not stratify or reduce viscosity after placement, so it is very suitable for the production of construction glue. Used in hydroxypropyl methyl cellulose daily chemical industry: used as shampoo, shampoo, thickener. Our instant products have high transparency (transmittance), good dispersibility in cold water, high purity and stable properties, and are very suitable for the production of shampoo products. Hydroxypropyl methyl cellulose is also widely used in new building materials and construction, used in mechanical construction such as wall building, stucco, painting, caulking, etc., suitable for dry mixing, mixing mortar, thickening water retention and adhesion, improving slurry pumpability, in decorative construction, used for pasting tiles, marble, etc., with high pasting strength, and can also reduce the amount of cement used. It is used for plastering gypsum, insulation mortar, water-resistant putty, bonding gypsum, caulking plaster, etc. Used as a thickener in the coating industry, it can make the coating bright and delicate, and improve its leveling. Hydroxypropyl methyl cellulose is also widely used in ceramics, batteries, textile printing and dyeing industries. 02 5. Hydroxypropyl methyl cellulose (HPMC) packaging and storage and transportation: 1 package: external three-composite plastic bag packaging, internal plastic film bag packaging, net weight 25KG per package. 2 Storage: moisture-proof and sun-proof, sealed and ventilated. 3 Transportation: Transportation according to moisture-proof general chemicals. 02Welcome friends in the building materials industry to inquire!
