Embodiment 1

[0044] see Figure 1-10 , a micro-ceramic vitrification process of ultra-fine grinding and microwave sintering of garbage fly ash, the main steps of which include:

[0045]S1. Preparation of the carrier rod, grinding and mixing the raw materials for the production of glass-ceramic for removing fly ash according to the proportion, and the above-mentioned raw materials mainly include SiO 2 and Al 2 O 3 , and its mass ratio is 1.5:1. After heating the raw material to 150 degrees Celsius, it is hot-pressed to obtain a carrier rod 1. After that, the carrier rod 1 is put into cold water for rapid water cooling, so that the surface and the interior of the carrier rod 1 form more A temperature change crack 102 is obtained to obtain a carrier rod;

[0046] The raw materials are mixed with a plurality of attachment fibers 103 and mixed uniformly to increase the strength of the formed carrier body 101, so that the carrier body 101 is not easily broken along the plurality of temperatur...

Abstract

The invention discloses a glass-ceramic vitrification process for ultrafine grinding and microwave sintering of waste fly ash, and belongs to the field of glass-ceramic manufacturing processes, and the glass-ceramic vitrification process for ultrafine grinding and microwave sintering of waste fly ash comprises the following steps: manufacturing a carrier rod from fly ash-removed raw materials of glass-ceramic, and carrying out shock cooling treatment to obtain the glass-ceramic. A large number of temperature change cracks appear on the surface of the carrier rod, fly ash is stored through the temperature change cracks, in the fly ash mixing process, the fly ash is immersed into the temperature change cracks through ultrasonic waves, meanwhile, the fly ash is locked through the attachment fibers, and the fly ash is captured and reserved in the temperature change cracks through a three-dimensional space structure composed of the attachment fibers. In the subsequent drying process, crystal particles of fly ash are easily formed on the inner wall of the temperature change crack, and in the subsequent grinding process, the raw materials are easily and uniformly mixed, so that the mixing degree of the glass ceramic production raw materials can be greatly increased, and the performance of the glass ceramic formed by microwave sintering is improved.

Description

technical field [0001] The invention relates to the field of glass-ceramic manufacturing technology, and more particularly, to a micro-ceramic vitrification process of garbage fly ash ultra-fine grinding and microwave sintering. Background technique [0002] Waste incineration is the main way to deal with domestic waste today. The fly ash produced in the waste incineration process is rich in heavy metal elements such as lead, zinc, chromium, and copper, which will cause serious pollution to the environment. Strict recycling treatment is required, generally by means of anti-seepage landfill, cement solidification, melting solidification, etc., and there is a risk of toxic heavy metal leaching. [0003] With the development of microwave sintering process, people have discovered new uses for garbage fly ash, which can be used as raw material for glass-ceramic production. Raw material SiO 2 and Al 2 O 3 It is mixed and sintered according to the proportion to obtain the glass...
