PCC (Precipitated Calcium Carbonate), is synthetically produced from quicklime by chemical precipitation method. PCC is used as a functional mineral filler in many sectors, with its high CaCO3 content and low impurity, variety of crystal structure/morphology and homogeneous partical size distribution.
PCC can be produced in different morphologies according to its usage areas. Needle-shaped aragonite, scalenohedral, prismatic and rhombohedral structures are typical cyristal types of PCC.What makes PCC unlike ?
Hence PCC is being produced by chemical methods, it is possible to get nano sizes and in different crystal shaped products which can not be achieved by mere grinding and the partical size distribution can be kept under control. These superiorities give PCC function and with the use of PCC production costs are decreased.
PCC adds some extra properties to the product such as strength, opacity, whiteness, brightness and viscosity regulation (thixotropy). Due to these properties, PCC is preferred to be used in many sectors like paint, plastic, paper, food, pharmacy, chemistry etc.PCC Usage AreasadaCAL is used in paper production as functional filler and coating mineral. It positively changes, both chemical and physical/optical properties of the paper.with adaCAL use in paper as filler;
with adaCAL use in paper as coating pigment;
- Add paper opacity/birghtness and whiteness.
- Increase the bulk density of paper.
- Improves the smoothness of the paper surface.
- Reduces dusting.
- Enhances bonding interaction with fibers.
- By stabilizing the retention/drainage system, allows better paper machine runnability.
- By significantly increase sheet filler content, reduces the production cost.
- Add paper birghtness and whiteness.
- Performs optimum rheological properties and provides ideal thixotropy.
- Improves opacity.
- By balancing ink absorption, improves the print quality.
