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:

Polycarboxylate ether water reducing agent is a commonly used concrete admixture used to adjust the fluidity and workability of concrete. The size of its dosage will have an impact on the performance of concrete.

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.

The addition of water reducing agents can effectively reduce the amount of cement used in concrete, reduce the self weight of concrete, reduce the burden of construction, and reduce losses during the construction process.

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

Slow-release monomers, functional monomers, reactive monomers.

redispersible latex powders have a wide range of applications.

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.

PVC adhesive resin has a wide range of applications in the construction industry. It can be used to make various building materials, pipeline systems, insulation materials, and waterproof materials, improving the functionality, safety, and durability of buildings.
