Basic Concept of Redispersible Powder

0 Comment

Basic Concept of Redispersible Powder   The Redispersible Powder is the main additive of dry powder ready-mixed mortar such as cement-based or gypsum-based. The Redispersible Powder is a polymer of vinyl acetate and ethyl ester which is spray-dried and gathered from the original 2μm to form spherical particles of 80-100μm. Since the surface of these.. read more →

Application of Cellulose Ether in Dry Mortar   In the dry mortar, cellulose ether plays the role of retaining water, thickening and improving construction performance. Good water retention performance ensures that the mortar will not be sanded, dusting and strength due to lack of water, cement hydration incompleted, thickening effect makes the structural strength of.. read more →

Fineness of Cellulose Ether

0 Comment

Fineness of Cellulose Ether   Fineness is also an important performance indicator for cellulose ether. The Hydroxypropyl Methylcellulose requirement for dry mortar is powder, low water content, and the fineness also requires 20%-60% of particle size to be less than 63um. Fineness affects the solubility of cellulose ether. The coarser Hydroxypropyl Methylcellulose is usually in.. read more →
