Hydroxypropyl methyl fiber (HPMC) is a water soluble polymer, which is commonly used to prepare capsules, tablets, cream, etc. in medicine, food and cosmetics. The following are some dissolution methods for hydroxypropyl methyl fibers:

Building materials: HPMC can be used as an additive for building materials, such as mortar, gypsum board, ceramic tile adhesive, etc. It can improve the adhesion, ductility, and water resistance of materials. Wall coatings: HPMC can be used as a thickener and humectant for wall coatings, improving their viscosity, leveling, and adhesion.

External wall insulation is composed of polymer mortar, glass fiber mesh cloth, flame-retardant molded polystyrene foam board (EPS) or extruded board (XPS) and other materials, which are bonded on site

Method and selection of using hydroxypropyl methyl cellulose (HPMC) in different application scenarios. For concrete putty powder, choose HPMC with a viscosity of 100000 and mix it directly with dry powder in a ratio of 3/1000. When using, add water directly because the cellulose has been completely mixed with the putty powder and there will be no agglomeration phenomenon. For the preparation of building adhesives, choose cold water soluble cellulose with a viscosity of 200000 and adjust the dosage as needed. HPMC gradually shows consistency after being placed in water, reaching its maximum consistency within approximately ten minutes. For spraying applications, choose cold water instant HPMC, with a shorter initial viscosity time as long as it does not clump.

Hydroxypropyl Methyl Cellulose) is a water-soluble polymer compound commonly used in construction materials, medicine, food, cosmetics and other fields. Here are some details about the use of HPMC

In recent years, with the continuous development of external insulation technology, hydroxypropyl methyl cellulose production technology progress, as well as hydroxypropyl methyl cellulose HPMC itself has excellent characteristics, hydroxypropyl methyl cellulose HPMC in the construction industry has been widely used. In order to investigate the interaction mechanism between HPMC and cement-based materials, this paper focuses on the improvement effect of HPMC on the cohesion of cement-based materials.

High-quality HPMC can be evenly and effectively dispersed in cement mortar and gypsum based products, and wrap all solid particles, and form a layer of wetting film. The moisture in the base is gradually released over a long period of time, and hydrates with inorganic cementitious materials, thus ensuring the bonding strength and compressive strength of the materials. Therefore, in high temperature summer construction, in order to achieve the water retention effect, it is necessary to add enough high-quality HPMC products according to the formula, otherwise, quality problems such as insufficient hydration, strength reduction, cracking, hollowing and falling off caused by drying too fast will occur, and the construction difficulty of workers will also be increased. As the temperature decreases, the amount of HPMC can be gradually reduced, and the same water retention effect can be achieved.
