Embodiment 1

[0035] A liquid grinding aid for improving the grinding efficiency of steel slag, prepared from the following components in parts by weight: 15 parts of grinding aid dispersant, 4 parts of solubilizer, 25 parts of inorganic salt, 4 parts of polyethylene glycol, 32 parts of water. The determination of the optimal component is by comparing the quality and grinding aid effect of different components of liquid grinding aids, as shown in Table 1.

[0036] Table 1 The quality and grinding aid effect of different components of liquid grinding aid

[0037]

[0038]As can be seen from the data in Table 1, when the grinding aid dispersant is a silicone surfactant, the solubilizer is polysorbate 80, the inorganic salt is sodium hexametaphosphate and sodium polyphosphate, and polyethylene glycol is polyethylene glycol. When the diol is 400, the liquid grinding aid is clear without turbidity, and the grinding aid effect is excellent. The sodium polyphosphate described in table 1 is a ...

Embodiment 2

[0041] A liquid grinding aid for improving the grinding efficiency of steel slag, prepared from the following components in parts by weight: 15 parts of grinding aid dispersant, 4 parts of solubilizer, 25 parts of inorganic salt, 4 parts of polyethylene glycol, 32 parts of water; described grinding aid dispersant is organic silicon surfactant, and described solubilizer is polysorbate 80, and described inorganic salt is sodium hexametaphosphate and sodium tetrapolyphosphate, and its weight ratio is 0.7:1, The polyethylene glycol is polyethylene glycol 400.

[0042] The organosilicon surfactant described in this embodiment is polyoxyethylene ether trisiloxane, polyether modified silicone oil, polyether modified heptamethyltrisiloxane or polyether phosphate modified siloxane any kind.

[0043] For the purpose of mixing the liquid grinding aid in the steel slag, the amount of the liquid grinding aid in this embodiment is 0.48% of the mass of the steel slag.

Embodiment 3

[0045] A liquid grinding aid for improving the grinding efficiency of steel slag, prepared from the following components in parts by weight: 10 parts of grinding aid dispersant, 2 parts of solubilizer, 30 parts of inorganic salt, 6 parts of polyethylene glycol, 32 parts of water. Others are with embodiment 2.

Abstract

The invention discloses a liquid grinding aid capable of improving steel slag grinding efficiency. The liquid grinding aid capable of improving the steel slag grinding efficiency not only solves the problem that the grinding aid is expensive because the conventional grinding aid adopts triethanolamine, but also solves the problem that the liquid grinding aid is easy to crystallize and precipitateunder the condition of low temperature. According to the technical scheme, the liquid grinding aid capable of improving the grinding efficiency of the steel slag comprises the following components inparts by weight: 5 to 30 parts of a grinding aiding dispersant, 1 to 10 parts of a solubilizer, 10 to 35 parts of inorganic salt, 1 to 10 parts of polyethylene glycol and 15 to 50 parts of water. Thesteel slag liquid grinding aid is prepared by compounding the conventional chemical raw materials; the raw materials are sufficient, low in cost and free of pollution; the preparation process is simple; the finished product has stable quality and performance; the steel slag grinding characteristic can be obviously improved; the steel slag grinding efficiency is effectively improved.

Description

technical field [0001] The invention relates to a liquid grinding aid, in particular to a liquid grinding aid for improving the grinding efficiency of steel slag. Background technique [0002] Steel slag is the waste slag discharged during the steelmaking process, and it is also a reusable silicate material. However, the utilization rate of steel slag in my country is only 10%, which not only causes environmental pollution, but also restricts the sustainable development of iron and steel enterprises. From a theoretical analysis, steel slag can be used in the fields of cement, concrete and other building materials. The application of steel slag in this field is to grind granular steel slag to make steel slag fine powder. However, due to the chemical composition of steel slag itself, the activity is low. In order to give full play to its performance, the steel slag must be ground to a sufficient fineness , that is, the specific surface area is not less than 400m 2 / kg. Ther...
