Nghiên cứu về tác động của chất kết dính cellulose trong sản xuất vật liệu mới
Methyl hydroxyethyl cellulose, also known as MHEC and Methylcellulose, is a thickening agent used in paints and coatings. The chemical compound can help prevent paint from sagging and dripping when it dries. The combination can also help provide the color with extra adhesion, making it helpful in constructing buildings. MHEC is commonly used as a thickening agent in decorative paints. Decorative paints are not as strong as structural paints, so they need thickening agents to help them adhere to walls and other surfaces without breaking apart or peeling away. MHEC provides water resistance to decorative paints, making it more difficult for walls to become damaged by exposure to water. It also helps make paint that has been applied easier to clean.
This study was conducted using a CEM I 52.5N sample (“Milke®” from HeidelbergCement AG, Heidelberg, Germany). Its properties are presented in Table 1. Composition of the cement was obtained by Q-XRD using a Bruker axs D8 Advance instrument (Bruker, Karlsruhe, Germany) with Bragg–Brentano geometry. Topas 4.0 software was employed to quantify the amounts of individual phases present in the sample by following Rietveld's method of refinement. The amounts of gypsum (CaSO4·2H2O) and hemi-hydrate
3. Water Retention: In construction materials like mortars and grouts, MHEC improves water retention, workability, and adhesion.
Furthermore, MHEC enhances the water resistance of cement. When MHEC is added to the mix, it forms a protective barrier that prevents water from penetrating the cement structure. This is particularly important in applications where the cement will be exposed to moisture, such as in swimming pools or basements. The improved water resistance provided by MHEC ensures that the cement remains strong and intact, even in wet conditions.
