Abstract
Panel glass first, is carried out broken ball milling and obtains CRT panel glass powder by a kind of preparation method of environmental protection Vuggy rock granular materials；Then, by CRT panel glass powder, manganese dioxide, sodium nitrate, lithium nitrate, antimonous sulfide are put into ball milling in ball mill and form batch；Batch is loaded and send in mould in roller kilns, after 5～10min of insulation, with the ramp of 4～8 DEG C/min to 770～780 DEG C；Then, then with the ramp of 0.2～1 DEG C/min to 780～790 DEG C；Then, less than 50～80 DEG C are cooled to then with the rate of temperature fall of 80～200 DEG C/min, crushing and screening obtains final product environmental protection Vuggy rock granular materials.Obtained in of the invention, environmental protection Vuggy rock granular materials intensity is high, and water absorption rate is high, and ventilating slit is high, and blowing temperature is low, and use cost is low, during production and use will not produce pollution to environment.Can be used as new materials such as the water quality purification materials such as excellent rainwater underground storage, rivers and creeks, lake, reservoir, fishpond, heat-insulating, fire-preventing building materials.
Description
Technical field
The present invention relates to a kind of manufacture method of Vuggy rock material, more particularly to a kind of using discarded CRT panel glass systems
The method of standby Vuggy rock granular materials.
Background technology
China is the production and consumption big country of household electrical appliance, and at present, China has come into television set and computer updates and changes
The peak period in generation, the cathode-ray tube (CRT) that annual superseded amount up to more than 8,000,000, will account for 55～65wt% of main screw lift are anxious
Suitable resource solution need to be found.Especially unleaded panel glass in CRT, if do not recycled, not only accounts for
With soil, and waste of resource, how discarded panel glass to be turned waste into wealth, become a difficult problem urgently to be resolved hurrily at present.
Lian Hui remittances etc. (even converge, Yuan Wenyi, Wu Xiaoyang, etc. foam glass is prepared using useless CRT panel glass for raw material
[J]. environmental project journal, 2012,6 (1)：292-296.) it is raw material using useless CRT panel glass, it is foaming agent from carbon black, boron
Sand, titanium dioxide, antimony oxide etc. are additive, using powder sintering, issue brewed standby low-density insulation bubble at 820 DEG C
Foam glass.The method preparation temperature is more than 800 DEG C, and prepared material is sealed porosity, is only capable of using as insulation material.
Mainly using cathode-ray tube glass part in DE 19702560A1, interpolation foaming agent and auxiliary agent and binding agent is crushed,
Add water, mixed, after granulation formation in rotary kiln fire graininess foam glass, be mainly used in light-weight building every
The aggregate of hot material.Tian Yingliang etc. (Tian Yingliang, Zhang Youliang, Tian Hui. using waste image tube develop foam glass [J]. glass with ward off
Porcelain .2003,31 (4):44-47.) with tube panel and pipe cone mass ratio as 65：35 used as major glass raw material, adds 0.4%200 mesh
Carbon black is foaming agent, and borax is additive, is equally prepared for foam glass using powder sintering.The method add fusing point compared with
Low pipe cone flint glass, prepared foam glass material cannot be used for the packing material of soil, it is impossible to used as crops
Water conservation gas permeable material is used.
CN1807314A discloses a kind of preparation method of crystallite foam glass, first, waste and old after electron gun to removing
The glass surface of cathode-ray tube is cleaned, and removes fluoresent coating and aperture plate, is then crushed, grind and cross 200～
300 mesh sieves；Then, by above-mentioned useless cathode-ray tube glass powder that percentage by weight is 94～97% and 3～6% carborundum powder
Ball milling mixing in ball mill is put into, Ball-milling Time is 30～60 minutes, then loads the batch being well mixed in mould, with
8 DEG C/min of heating rate rises to from room temperature and preheat at 650 DEG C；Risen from 650 DEG C with 10～12 DEG C/min of heating rate again
To 840～900 DEG C and after being incubated 20～40 minutes and being foamed, 550 DEG C are cooled to 20 DEG C/min of cooldown rate,
And it is incubated 20～60 minutes；Finally, room temperature is annealed to 1 DEG C/min of speed slow cooling and obtains crystallite foam glass.Should
Method adds the relatively low pipe cone flint glass of fusing point, while foaming, crystallization temperature is higher, prepared foam glass material is not
The packing material of soil can be used for, it is impossible to which the water conservation gas permeable material as crops to be used.
Vuggy rock also known as float stone or foam, is the nature of glass acidity volcano effusive rock of a kind of porous, lightweight, and its composition is suitable
In rhyolite.Vuggy rock rough surface, particle unit weight are 450kg/m3, loose volume weight is 250kg/m3Left and right, porosity 7l.8-
81%, water absorption rate is 50-60%.Vuggy rock is mainly used as ventilative water-keeping material, and loosing soil agent in gardening plantation.?
Adrainage material is mainly used as in roof, garage top row water, its good absorbent function can also supplement moisture needed for plant simultaneously.
