Definitions
- the present invention relates to a method for producing a precipitated carbonic carbonate using algal egg quality, such as dalgal 3 ⁇ 4 quality, more specifically, the heat treatment step, pulverization step, dry digestion step, carbonation step and filter drying step.
- algal egg quality such as dalgal 3 ⁇ 4 quality
- the present invention relates to a method for producing a precipitated carbonic carbonate using algae egg shell such as dalgal, more specifically, comprises a heat treatment step, grinding step, dry digestion step, carbonation step and filtration drying step.
- Lime product has been continuously increasing industrial demand over the last few decades, which is divided into heavy calcium carbonate obtained by direct grinding of limestone and precipitated calcium carbonate produced by chemical methods.
- the particle shape is uneven, but in the case of precipitated calcium carbonate, the particle size is very small and even, so the fine chemical industry such as paper, plastic and rubber, as well as household goods such as paint, toothpaste and stationery, food and medicine It is a high value added material that can also be used in the field.
- limestone has a low thermal dissociation rate due to its large grain size and dense structure, which is low because heat transfer through pores in coarse limestone is difficult and carbon dioxide produced as a result of pyrolysis is difficult to escape through the dense structure of limestone.
- the partial pressure of carbon dioxide is relatively increased, which leads to a slow pyrolysis rate. Due to this problem, heat treatment needs to be performed at a high temperature, thereby increasing manufacturing costs.
- precipitated calcium carbonate prepared using limestone contains a lot of impurities. And, there was a problem that the environment is polluted by the carbon dioxide generated during the pretreatment of limestone.
- Another object of the present invention is to provide a method for preparing sedimentary calcium carbonate using algae shells that can easily control the particle size and produce highly precipitated calcium carbonate.
- Still another object of the present invention is to provide a method for preparing sedimentary carbonic acid carbonate using algae shells to prevent environmental pollution by recycling carbon dioxide generated in the heat treatment step.
