AI Technical Summary

Problems solved by technology

In order to meet the needs of the market, artificial pumice came into being, and the existing artificial pumice is processed by inorganic materials, caustic soda, borax, calcium carbonate powder, carbon powder and mica according to a certain proportion and special technology. Many types of raw materials are required, the processing technology is complicated, and the chemical composition and physical structure are quite different from those of natural pumice. It only solves the problems of internal voids and bulk density, resulting in a limited range of use.

Embodiment 1

[0012] A preparation method of artificial basaltic pumice, comprising the following steps:

[0013] (1) The basalt is sent to the furnace to be heated to 1450-1500°C to melt and form a liquid;

[0014] (2) The liquid flows through the feeding tank, and helium is filled into the feeding tank to fill the molten liquid with air bubbles, and then it is poured into the mold from the feeding port to cool and form, and finally prepared into basaltic pumice.

Embodiment 2

[0016] A preparation method of artificial basaltic pumice, comprising the following steps:

[0017] (1) The basalt is sent to the furnace to be heated to 1350-1450°C to melt and form a liquid;

[0018] (2) The liquid flows through the feeding tank, and inert gas is filled into the feeding tank to fill the molten liquid with air bubbles, and then it is poured into the mold from the feeding port to cool and form, and finally prepared into basaltic pumice.

Embodiment 3

[0020] A preparation method of artificial basaltic pumice, comprising the following steps:

[0021] (1) The basalt is sent to the melting furnace to be heated to 1500-1650°C to melt and form a liquid;

[0022] (2) The liquid flows through the feeding tank, and helium is filled into the feeding tank to fill the molten liquid with air bubbles, and then it is poured into the mold from the feeding port to cool and form, and finally prepared into basaltic pumice.

Abstract

The invention discloses a preparation method of artificial basaltic pumice. The method comprises the following steps of conveying basalt into a melting furnace, and heating the basalt to 1350-1650 DEG C for melting to form a liquid; enabling the liquid to flow through a feeding pool, filling the feeding pool with an inert gas until the molten liquid is full of bubbles and then loading the liquid into a mold from a feeding opening to cool and mold; and finally preparing the basaltic pumice. The method is available in raw materials, simple in processing process and low in cost; the performance of a product is similar to that of natural pumice.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a preparation method of artificial basaltic pumice. Background technique [0002] There are two types of pumice: natural pumice and artificial pumice. Natural pumice is a porous, light glassy acidic volcanic extrusive rock. It is a glassy lava with dense pores formed by the condensation of molten magma with volcanic eruption. The volume of pores accounts for more than 50% of the rock volume, and the surface is rough. , the particle bulk density is 450Kg / m³, the loose bulk density is 250kg / m³, the porosity of natural pumice is 71.8-81%, and the water absorption rate is 50-60%. It is named pumice stone because of its large porosity, light weight, bulk density less than 1g / cm³, and ability to float on water. It is characterized by light weight, high strength, acid and alkali resistance, corrosion resistance, and no pollution and radioactivity. It is an ideal natural, ...
