Embodiment Construction

[0035] Embodiment: get the phosphorus slag of certain enterprise discharge in Guizhou Province as raw material, its chemical composition (mass fraction) is as shown in the following table after testing:

[0036] Composition: SiO 2 Al 2 o 3 CaO MgO Fe 2 o 3 P 2 o 5 Loss on ignition

[0037] Content %: 37.56 3.29 47.44 1.91 0.38 3.25 6.17

[0038] The first step, prepare materials:

[0039] Get phosphorus slag 95kg, quartz sand 60kg, soda ash 14kg, aluminum oxide 6.5kg, zinc oxide 4kg, magnesium oxide 6kg, barium carbonate 4kg, coloring agent 0.5kg, phosphorus slag removes impurities such as iron and coal ash wherein with conventional method, then Dry with hot air, ball mill into powder with a fineness of 80 mesh to 100 mesh, and set aside. Quartz sand should also be ball-milled into powder, with a fineness of 100 mesh to 80 mesh, for later use.

[0040] Step two, ingredients:

[0041] After the above materials are accurately weighed, mixed, stirred evenly,...

Abstract

The invention discloses a method for producing calendared glass-ceramic decorative board by phosphorous slag, comprising the following steps of: step 1: preparing, namely, taking phosphorous slag, arenaceous quartz, calcined soda, alumina, zinc oxide, magnesia, barium carbonate and colorant according to a formulation; step 2: compounding, namely, mixing the materials uniformly to be used later; step 3: sintering glass melting liquid; step 4: pressing the glass melting liquid as a rough plate body of the glass-ceramic decorative board; step 5: annealing and cooling to prepare the rough plate of glass-ceramic decorative board; and step 6: grinding, polishing and cutting the rough plate, thus preparing the finished product. The glass-ceramic decorative board produced by the method has the advantages of excellent physical and mechanical property, uniform and fine quality, durable luster of the plate, pollution resistance, color-adjusting, no-pore, no radioelement pollution and the like. The method has mature process, simple operation and easy control, can effectively reduce the pollution of the phosphorous slag and yellow phosphorus tail gas to the environment, and takes the yellow phosphorus slag as raw material and the tail gas as the heat energy raw material to produce the calendared glass-ceramic decorative board. The method complies with the requirements of emission reduction, energy-saving, environment-protection, health and safety requested by National Environment Protection Commission and National Development and Reform Commission, is beneficial for improving the environment, provides high-class and safe decorative material for the building and has excellent social environment.

Description

technical field [0001] The present invention relates to glass-ceramic, in particular to a method for producing a rolling-type glass-ceramic decorative plate using yellow phosphorus slag as a raw material. Background technique [0002] 1. Glass-ceramic decorative panels are made of natural inorganic materials under high-temperature conditions similar to those of natural granite, which are melted at high temperatures, controlled crystallization and other glass recrystallization processes, so that the original single glass phase is formed by microcrystalline phase and The glass phase is evenly distributed, a composite high-grade green environmental protection building decoration material, which combines the superior properties of glass and ceramics, and its performance indicators are superior to natural stone and other artificial stones, and does not contain any radioactive elements, no radiation Pollution, in line with the provisions of the National Environmental Protection Co...
