Embodiment 1

[0023] The raw materials are prepared according to the following parts by weight: 4.5 parts of clay, 3.5 parts of metal smelting solid waste slag, 1.5 parts of feldspar, 0.5 part of talc, and an appropriate amount of water. The raw materials are stirred, kneaded, extruded, and separated by a twin-shaft kneader to form mud. The kneaded mud is put into the stale pool for 24 hours to improve the workability of raw materials and the wettability of water. Due to the high plasticity of industrial solid waste Poor, so 50% of the raw materials are ground into a powder of 180 mesh or more with a mill. The mixed raw materials are heated by using the waste heat of the tunnel kiln to heat the steam generated by the steam oven, and then extruded by an extrusion molding machine under vacuum conditions. Raising the raw material temperature will produce a smooth film between the raw material and the extrusion molding machine, increase the lubricity, reduce the resistance of the billet during ...

Embodiment 2

[0025] The raw materials are prepared according to the following parts by weight: 5 parts of clay, 3 parts of metal smelting solid waste slag, 1.5 parts of feldspar, 0.5 part of talc, and an appropriate amount of water. The raw materials are stirred, kneaded, extruded, and separated by a twin-shaft kneader to form mud, and the kneaded mud is placed in the stale pool for 36 hours to improve the workability of raw materials and the wettability of water, because industrial solid waste is very plastic Poor, so 50% of the raw materials are ground into a powder of 180 mesh or more with a mill. The mixed raw materials are heated by using the waste heat of the tunnel kiln to heat the steam generated by the steam oven, and then extruded by an extrusion molding machine under vacuum conditions. Raising the raw material temperature will produce a smooth film between the raw material and the extrusion molding machine, increase the lubricity, reduce the resistance of the billet during extru...

Embodiment 3

[0027]The raw materials are prepared according to the following parts by weight: 5.5 parts of clay, 2.5 parts of metal smelting solid waste slag, 1.5 parts of feldspar, 0.5 part of talc, and an appropriate amount of water. The raw materials are stirred, kneaded, extruded, and separated by a twin-shaft kneader to form mud, and the kneaded mud is put into the stale pool for 48 hours to improve the workability of raw materials and the wettability of water, because industrial solid waste is very plastic Poor, so 50% of the raw materials are ground into a powder of 180 mesh or more with a mill. The mixed raw materials are heated by using the waste heat of the tunnel kiln to heat the steam generated by the steam oven, and then extruded by an extrusion molding machine under vacuum conditions.

Abstract

The invention relates to the technical field of building materials for pavement, in particular to glaze kerb stone and a manufacturing method thereof. The problems that an existing forming process is simple, cracks easily appear in the drying process, the rejection rate is high, strength is not enough, and the technological sintering time is long are solved. The glaze kerb stone is prepared from, by weight, 4.5-5.5 parts of clay, 2.5-3.5 parts of metal smelting solid waste slag, 1.5 parts of feldspar, 0.5 part of talc and a proper amount of water. The preparation method includes the steps of smashing, mixing, green body forming, glazing and sintering, wherein mixing refers to kneading of smashed raw materials by means of a kneading machine, the kneaded raw materials are put in a rotting pond to be rot for 24-48 h, the yield during product drying is facilitated, dried green bodies are smooth in surface, glazing is convenient, and the production cycle of the product is shortened.

Description

technical field [0001] The invention relates to the technical field of building materials for paving, more specifically, to a glazed curb stone and a manufacturing method thereof. Background technique [0002] At present, roadside stone manufacturers on the market purchase various types of hydraulic forming machines to mix and press cement, sand, and stones into concrete of a certain specification as roadside stones. In actual use, it will be gradually damaged and weathered by wind, sun and rain. Obtain marble from the ecological environment, and then use marble to cut into certain specifications of roadside stones. At the same time, more scraps, dust, marl, and sewage will be formed during the cutting process. [0003] The long-term storage of industrial waste solid waste not only occupies a large amount of land, but also causes serious pollution and harm to water systems and the atmosphere. How to rationally use industrial waste has become a hot topic and the focus of at...
