READ MOREIntroduction to HPMC:
HPMC, called hydroxypropyl methylcellulose, is the English abbreviation of Hydroxypropyl Methyl Cellulose. It is a synthetic chemical compound obtained from natural cellulose fibers through a series of chemical treatments. The details are as follows:
Appearance and properties: HPMC is in the form of white or off-white powder with high particle size. It usually has good physical properties such as carbonization temperature, apparent density and specific gravity. It is easily soluble in water and some solvents, such as ethanol/water, propanol/water, trichloroethane, etc. in appropriate proportions. The aqueous solution has surface activity, high transparency, and stable performance.
Main uses: HPMC is widely used in the industrial field. It is mainly used as a dispersant in the production of polyvinyl chloride and is the main additive for the preparation of PVC by suspension polymerization. In addition, HPMC is often used as a thickener, stabilizer, emulsifier, and excipient in the production of other petrochemicals, coatings, building materials, paint removers, agricultural chemicals, inks, textile printing and dyeing, ceramics, papermaking, cosmetics, etc. Agents, water-retaining agents, film-forming agents, etc. are used. In the construction industry, HPMC is mainly used in mechanized construction such as wall building, stucco decoration, and caulking. Especially in decorative construction, it is used to paste ceramic tiles, marbles, and plastic decorations. It has high bonding strength and can also reduce the amount of cement.
Production process: The production process of HPMC usually includes steps such as liquid caustic soda impregnation of refined cotton or wood pulp, etherification reaction, neutralization washing, drying and crushing. The etherifying agent usually uses methyl chloride and propylene oxide, and the product is obtained through one-step etherification method or step-by-step etherification method.
Introduction of HPMC to improve the performance of materials:
As a multifunctional additive, HPMC can effectively improve buildings by enhancing adhesion, improving fluidity and plasticity, increasing water resistance and impermeability, improving crack resistance, improving surface quality and adjusting rheological properties. Material properties that improve the quality and durability of buildings. The following are specific performance characteristics:
1. Enhance adhesion: Adding an appropriate amount of HPMC can improve the adhesion of cement, mortar and other building materials, improve the adhesion and durability of materials, reduce cracking and shedding of materials, and increase the stability of buildings.
2. Improve fluidity and plasticity: HPMC can improve the fluidity and plasticity of concrete, mortar and other materials, making it easier to construct and vibrate, thereby improving the working performance and molding performance of building materials.
3. Increase water resistance and impermeability: Adding HPMC to cement, mortar and other materials can improve their water resistance and impermeability, reduce water penetration, prevent the material from becoming damp, moldy and cracked, and increase the durability of the building.
4. Improve crack resistance: HPMC can improve the crack resistance of concrete, mortar and other materials, reduce cracks caused by drying shrinkage and thermal expansion and contraction, and increase the crack resistance of building materials.
5. Improve surface quality: Adding an appropriate amount of HPMC can improve the leveling and dripping resistance of paint, tile adhesive and other coating materials, making the paint easier to apply, making the coating more uniform and smooth, and improving the surface quality of the building.
6. Adjust rheological properties: As a rheological agent, HPMC can adjust the rheological properties of building materials, improve the stability and processability of materials, and ensure the smooth progress of the construction process.
How does HPMC prevent delamination and sedimentation of building materials?
In building materials, HPMC (hydroxypropyl methylcellulose) plays an important role, one of which is to prevent delamination and sedimentation of building materials. As a multifunctional additive, HPMC can form a uniformly dispersed system. When HPMC comes into contact with solid particles in an aqueous solution, it can evenly disperse these solid particles in the aqueous solution, preventing them from aggregating and settling, thereby maintaining the uniformity and stability of the material. And HPMC has good stability. In aqueous solution, HPMC forms a colloidal solution with good stability, which can stably disperse solid particles, prevent their precipitation and stratification, and maintain the consistency and reliability of the material. HPMC can also increase the adhesion of materials. It can firmly adhere solid particles to the surface of building materials, prevent them from separating and settling, and make the materials more stable and reliable. HPMC can adjust the rheological properties of building materials. It can adjust the fluidity and stability of the material, maintain the uniformity and consistency of the material during the construction process, and reduce the occurrence of delamination and precipitation.
