Exploring HPMC Applications and Benefits for Tile Adhesives and Grouts
In recent years, with the continuous development of external wall insulation technology, the continuous progress of cellulose production technology, and the excellent characteristics of HP cellulose itself, HP cellulose has been widely used in the construction industry. In order to deeply understand the mechanism of HP cellulose and cement-based materials, this paper introduces the improvement effect of HP cellulose on the cohesion of cement-based materials.
The working mechanism of MHEC as water retention agent in cement relies on two separate effects: first, its water sorption capacity and second the formation of hydrocolloidal associated 3D polymer networks. At low MHEC concentrations (≤ 6 g/L which corresponds to a dosage of 0.32% bwoc), water sorption presents the main mechanism for water retention while above this concentration, the first mechanism is supplemented by the formation of associated polymer networks which are highly effective in
