Problems solved by technology

The existing domestic production of foamed glass 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 foamed glass.
The traditional production process of foamed glass needs to be sintered with a mold box, manually demoulded, and cooled in an annealing kiln. The disadvantages of this process are: it consumes a lot of labor, the loss of the mold box is large, and the production efficiency is low, which leads to a substantial increase in the production cost of the product. Difficult to promote on a large scale

Abstract

The invention discloses a honeycomb glass pumice formula and a production process thereof. The formula comprises the following components in percentage by weight: 89 to 96.5 percent of glass particles, 0.6 to 5.8 percent of zeolite powder, 0.6 to 3 percent of borax, 0.3 to 1.2 percent of heavy calcium carbonate powder and 0.3 to 1.2 percent of light calcium carbonate powder. The production process comprises the following four steps of preparing materials; sintering and puffing at high temperature; cooling; smashing and screening. Accurate furnace internal temperature control is realized by increasing the material mixing accuracy and strictly controlling the conveying belt speed of a sintering furnace, so as to realize uniform porosity of honeycomb glass pumice, and the honeycomb glass pumice which is 0.25 to 1.25 in specific weight, 0.8 to 120 percent in water absorption and 0.8 to 450 mu m in aperture can be prepared. Raw materials are derived from waste white transparent glass, so that environmental pollution is prevented in production and use processes, and utilization of renewable solid waste resources is realized.

Description

technical field [0001] The invention relates to a honeycomb glass pumice 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 and ball-milled, weighed into heat-resistant stainless steel mold boxes, and then enter the foaming kiln It is prepared by heating and foaming, and annealing in an annealing kiln to form a glass blank. The existing domestic production of foamed glass 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 foamed glass. The traditional production process of foamed glass needs to be sintered with a mold box, manually demoulded, and cooled in an annealing kiln. The disadvantages of this process are: it consum...
