Abstract
Description
technical field
[0001] The invention belongs to the field of building decoration materials, and more precisely relates to a production method for producing glass-ceramics by using waste glass and smelting waste residue. Background technique
[0002] The development of building materials is changing with each passing day, ranging from various large buildings to small houses, which are increasingly inseparable from decorative materials. The earliest decorative material used by humans is natural stone, and the commonly used varieties are granite, marble, etc. Architectural decorative ceramics are known as excellent decorative materials, and ceramic wall and floor tiles are the most widely used. Although the above two dominant traditional decorative materials have quite advantages, their weaknesses are: low flexural strength, poor water erosion resistance, easy to produce primary or secondary cracks, causing cracking, peeling off; in terms of durability, Due to the coarse cryst...
Examples
Embodiment 1
[0034] A production method for producing glass-ceramic by using waste glass and smelting waste residue,
[0035] ①Preparation of smelting waste slag: Mix a batch of 300 tons of smelting waste slag several times, inspect the slag to confirm the quality of the same batch of smelting waste slag is stable, and then pass through a vibrating sieve to screen the waste slag powder below 4 mesh for use.
[0036] ②Preparation of waste glass frit: crush a batch of waste CRT glass with a crusher, and then use a vibrating sieve to screen out glass pellets and powders under 3 mesh, and mix them with a forklift for later use.
[0037] ③ Analyze the chemical composition of the smelting slag and waste glass prepared above through scientific sampling, compare with the chemical composition of the glass-ceramic, determine the additional components that need to be added, and reasonably adjust the chemical composition and weight percentage as follows: SiO 2 50%-75%; CaO 5%-25%; Al 2 o 3 3%-15%;...
