Characteristics of the Treated Ground Calcium Carbonate ...

This study examined the surface properties, fluidity, flowability and floodability of untreated ground calcium carbonate (GCC) powder and treated GCC powder with stearic acid (SA) using a dry process coating system. The surface of GCC powder is generally hydrophilic, but was changed to a hydrophobic surface when coated with SA.

Influence of Calcium Carbonate Powder on Water

Bagasse ash (BA) is a plentiful byproduct obtained from the process of electricity generation during sugar manufacturing. We investigated the influence of adding calcium carbonate powder (CCP) to self-compacting mortar (SCM) mixtures. Type 1 Portland cement was replaced with 0%, 20%, and 40% as-received or ground BA and CCP by weight. Mixtures were designed to yield a slump flow spread of

Characteristics of the treated calcium carbonate particles ...

2019-6-12  Calcium carbonate (CaCO 3) is one of the most popular mineral fillers used in the polymer industry [1] and [2]. However, due to the hydrophilic nature of its surface, CaCO 3 is incompatible with hydrophobic polymers such as HDPE [3]. While larger particles can be incorporated into polymer, the smaller particles by virtue of enhanced particle ...

Effect of process conditions on spray dried calcium ...

2021-1-1  A series of spray drying experiments were carried out on calcium carbonate powder, to investigate the effect of three variables (gas flow rate, solids loading, and feed flow rate) on the yield and particle size of spray dried calcium carbonate. Porous, hollow spherical particles ranging between 14 and 201 μm were formed in a lab-scale spray drier.

Development of Coprocessed Chitin-Calcium Carbonate as ...

The use of chitin as an excipient in tablet formulation is limited because of certain drawbacks such as poor flowability and low true density. The objective of this work is to improve these properties through coprocessing of chitin with calcium carbonate (CaCO 3 ) by precipitating CaCO 3 on chitin particles using different methods.
