Sponge body foamed glass formula and production process thereof

Abstract

The invention discloses a sponge body foamed glass formula and a production process thereof. The sponge body foamed glass comprises the following components in percentage by weight: 96-99 percent of glass particles, 0.1-3.9 percent of potassium feldspar powder, 0.1-0.9 percent of shell powder and 0.1-0.9 percent of slaked lime. The process for producing the sponge body foamed glass comprises the following steps: S1, preparing materials; S2, sintering and bulking; and S3, cooling. According to the formula and the production process of the sponge body foamed glass disclosed by the invention, the defect that the traditional foamed glass production process is complicated is improved; and moreover, the formula of the sponge body foamed glass serves as a production raw material, and according to the production process of the sponge body foamed glass, the speed of a conveyor belt of a sintering furnace and the furnace temperature are controlled, and the sponge body foamed glass of which the specific gravity is 0.3-1.3, the water absorption rate is 1-110 percent and the pore size is 1.2-420 microns can be prepared.

Description

technical field [0001] The invention relates to a production formula of foamed glass and a manufacturing method thereof, in particular to a sponge foamed glass formula and a production process thereof. Background technique [0002] The existing production of foamed glass generally uses waste glass, fly ash, non-metallic minerals and other materials rich in glass phase as the basic raw materials, which are mixed, crushed, ball milled, weighed into a heat-resistant stainless steel mold box, and then heated in a foaming kiln. Foaming, and then annealing into glass blanks in a manual demoulding annealing kiln. The existing domestic foam glass production uses waste glass and other materials rich in glass phase as the basic raw materials. The foaming time and temperature of different components are not easy to control, which affects the quality of foam glass. The traditional foam glass production process requires sintering with mold boxes, manual demoulding, and cooling in an ann...

Problems solved by technology

The existing domestic foam glass production uses waste glass and other substances rich in glass phase as the basic raw materials. The foaming time and temperature of different components are not easy to control, which affects the quality of foam glass.

The traditional foam glass production process requires sintering with mold boxes, manual demoulding, and cooling in an annealing kiln. The disadvantages of this process are: it consumes a lot of labor, the loss of mold boxes is large, and the production efficiency is low, which leads to a substantial increase in product production costs. Difficult to promote on a large scale
