Problems solved by technology

This process mainly uses the decomposable part of limestone sludge to make pores for ceramsite, thereby effectively reducing the product's own weight, and can obtain ceramsite with light bulk density, but its strength is also relatively low. On the one hand, it is not suitable for hollow ceramic plates. At the same time, it cannot meet the requirements of high appearance quality, excellent mechanical properties and low water absorption of ceramic plates.
It can be seen that there are still some difficulties in the preparation of hollow ceramic plates using ferronickel slag as raw materials

Abstract

The invention belongs to the technical field of ferronickel residue industrial waste utilization, particularly relates to a hollow ceramic plate prepared by taking ferronickel residue as a raw material, and further discloses a preparation method of the hollow ceramic plate. According to the ferronickel residue hollow ceramic plate, industrial waste residue ferronickel residue is used as a raw material and interacts with additives such as a binder, a plasticizer, a fluxing agent and the like, so that the obtained hollow ceramic plate has the advantages of light weight and high strength, and ishigh in safety and wide in application field in application and construction processes; and the prepared ceramic plate uses industrial solid waste as a main raw material, the addition amount is as high as 72-90%, and the use amount of the ferronickel residue is high, so that the dependence on clay is avoided, secondary utilization of waste resources is achieved, and an effective and feasible way is provided for resource utilization of the ferronickel residue.

Description

technical field [0001] The invention belongs to the technical field of utilization of nickel-iron slag industrial waste, in particular to a hollow ceramic plate prepared by using nickel-iron slag as a raw material, and further discloses a preparation method thereof. Background technique [0002] Nickel-iron slag is an industrial waste slag produced by laterite nickel ore in the process of smelting nickel-iron alloy or refining nickel metal. With the gradual expansion of the scale of nickel-iron alloy in my country, the discharge of nickel-iron slag has also increased year by year. According to reports, in recent years, the annual discharge of ferronickel slag in my country has exceeded 30 million tons, and it has become the fourth largest smelting slag in my country after iron slag, steel slag and red mud. At present, the treatment methods of large-scale ferronickel slag are mainly piling treatment or deep sea landfill, which not only occupies land and pollutes the environme...
