Cellulose is a compound widely used in the chemical and pharmaceutical industries.

The 26th Russian International Chemical Exhibition (KHIMIA 2023) will be held from October 30 to November 2, 2023 at the Expo Center Exhibition Hall in Moscow, Russia.

The main raw material of HPMC is plant fiber, and its price is directly influenced by the supply and demand of plant sources. Seasonal and climate change factors may also have an impact on raw material prices.

About the use of hydroxypropyl methyl cellulose, hydroxypropyl methyl cellulose can be applied to various fields of building materials. The editor will explain the functions and effects of hydroxypropyl methyl cellulose one by one. Next, let's learn the following knowledge together with the editor~

Whiteness: Although whiteness cannot determine the usability of HPMC​, the addition of whitening agents during the production process can affect its quality. However, most good products have good whiteness.

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.
