Ceramic grinding aid for improving acid resistance, alkali resistance, water resistance and uniformity of magnesium cement and production method thereof

Abstract

The invention discloses a ceramic grinding aid for improving the acid resistance, the alkali resistance, the water resistance and the uniformity of magnesium cement and a production method thereof. The ceramic grinding aid comprise three components, wherein a component A is a prefermented product obtained by mixing 15-18 parts of corn starch, 0.2-0.3 part of yeast powder, 15-18 parts of sawdust, 0.2-0.3 parts of a cytophaga agent by weight and then fermenting for 18-20h; a component B is a foamed product obtained by foaming 150-180 parts of an aqueous sodium silicate solution containing 10% ofa sodium silicate solute, 2-3 parts of activated carbon powder and 2.2-2.4 parts of calcium oxide by weight for 3-5 days; a component C is a hard abrasive, namely 8-10 parts of silicon dioxide. The ceramic grinding aid has the effects of improving the acid resistance, the alkali resistance, the water erosion resistance and the halogenation resistance of the magnesium cement through modification of the magnesium cement, and has the technical effects of providing a buffering function, improving the cutting uniformity and improving the cutting efficiency.

Description

technical field [0001] The invention relates to the technical field of ceramic grinding, in particular to a magnesium cement anti-acid, alkali and water-resistant ceramic grinding aid for improving uniformity and a manufacturing method thereof. Background technique [0002] Magnesium cement uses lightly calcined powder obtained from calcined magnesite or ash powder obtained from calcined dolomite at low temperature (mainly composed of MgO) as a cementing agent, and water-soluble magnesium salts such as magnesium chloride hexahydrate (MgCL2 6H2O) as a blending agent. Then add water, and the formed light-burned magnesium powder and magnesium chloride hexahydrate are used as the main raw materials. Therefore, in general, magnesium cement refers to magnesium oxychloride cement. Magnesium cement can harden quickly under normal temperature and pressure to form artificial stone with relatively high brittleness and high hardness. Utilizing its hardening and gelling properties, it c...

Problems solved by technology

[0004] Cement ball mill is a necessary process and key link in cement production. Its energy consumption and electricity consumption account for 30% of the total energy consumption of cement production and more than 70% of the total electricity consumption. At present, the national low-carbon environmental protection requirements are getting higher and higher. Although The price of cement is rising rapidly and the profit margin is increasing. However, in the existing technology, with the development of technology, the traditional steel grinding balls have been gradually replaced by ceramic grinding balls, and the current equipment using ceramic ball grinding technology inevitably has two Problems: 1. Due to the low self-weight of ceramic balls, the extrusion force is insufficient at the same stirring rate, resulting in low ball milling efficiency, that is, the output efficiency of a single ball mill is low; 2. Because most of the ceramic balls in the prior art use rough Sintering technology, the structure is neither dense nor balanced, but also brittle and easy to break, so the loss in the ball milling process is faster than that of the original steel ball
