Description

Technical Field

[0001] The invention relates to the technical field of nano calcium carbonate processing, in particular to a processing device and a method for nano calcium carbonate. Background Art

[0002] Nano calcium carbonate is also called ultrafine calcium carbonate. Its standard name is ultrafine calcium carbonate. The most mature industry for the application of nano calcium carbonate is the plastics industry. It is mainly used in high-end plastic products. It can improve the rheological properties of plastic masterbatch and improve its formability. It can be used as a plastic filler to enhance toughness and reinforcement, improve the flexural strength and flexural elastic modulus, heat deformation temperature and dimensional stability of plastics, and also give plastics thermal hysteresis.

[0003] The existing nano calcium carbonate processing and production requires five stages: raw material preparation, calcination, gas washing, digestion, pulping, carbonization, activation, dehydration, drying, and packaging. During the carbonization process, a large amount of carbon dioxide needs to be added to the produced nano calcium carbonate to meet the carbonization requirements. In this process, not only is a large amount of energy consumed, but also due to the agglomeration of nano calcium carbonate during the production, carbon dioxide cannot fully contact the nano calcium carbonate, resulting in unsatisfactory carbonization. For this reason, we propose a processing device and method for nano calcium carbonate. Summary of the invention
