Specific embodiment
The present invention is further elaborated below by embodiment.
One embodiment of the invention provide it is a kind of using foam glass waste material as the foam glass of main material, in parts by weight, institute
The raw material for stating foam glass includes: foam glass waste material: 60~90 parts；Auxiliary material glass: 15~40 parts；Foaming agent: 0.15~
0.33 part；Fluxing agent: 0.10~0.80 part；Wherein, the auxiliary material glass includes teletron glass, plate glass and Bottle & Can glass
At least one of glass.
Foamed glass blank is in the first time production process before forming waste leftover material, in order to facilitate foam from diaphragm capsule
It takes out, release agent can be sprayed on diaphragm capsule, the ingredient of release agent is aluminium hydroxide (Al (OH)3), release agent can be with the shape of slurry
Formula sprays to the inner surface of diaphragm capsule, and the ball milling powder of foam glass after foaming kiln foams, forms foam glass inside diaphragm capsule
Green body.It after foam glass green body goes out foaming kiln, separates, anneals into annealing kiln, by for 24 hours~26h with diaphragm capsule by demoulding
Foamed glass blank is ultimately formed after annealing (eliminating the thermal stress in foam glass), last foundation various sizes are to foam glass
Blank carries out cutting and generates waste leftover material.The waste leftover material that the foamed glass blank generates carries out two as main material of the invention
It is secondary to utilize production foam glass.
The waste material for directlying adopt the formation of foam glass waste leftover material produces foam glass as raw material, does not have in the waste leftover material
Have other impurities ingredient, than directly use waste plate glass it is more clean, the processes such as impurity removing matter, dedusting, drying can be saved,
Significantly reduce cost of labor, power cost and equipment loss.
It should be noted that foam glass green body is taken out from foaming kiln when being demoulded, and since temperature is higher, release agent meeting
It is adhered on the green body of foamed glass blank.And the maximum temperature in foaming kiln is at 830 DEG C~900 DEG C, release agent aluminium hydroxide
(Al(OH)3) it will become aluminum oxide (Al at such a temperature2O3), the lower surface of foamed glass blank and surrounding are stained with
Aluminum oxide.
And in cutting process, the epidermis of foamed glass blank is removed by cutting, therefore containing a large amount of in foam glass waste material
The epidermis of foam glass namely the waste material of foam glass in can introduce a large amount of aluminum oxide (Al2O3).Aluminum oxide
Fusing point at 2050 DEG C, the blowing temperature highest of foam glass only has 900 DEG C, and blowing temperature is not enough to melt remaining release agent
Aluminum oxide.Due to will form a large amount of intercommunicating pore in foaming when aluminum oxide residual is more in foam glass waste material,
Lead to foam glass intermediate hierarchical, forms macroscopic-void.For the ratio for reducing aluminum oxide, formed in foam glass waste material useless
A kind of auxiliary material glass that aluminum oxide content is low is introduced in bubble powder, is foamed together with useless bubble powder.
The auxiliary material glass, viscosity is low when high temperature, is conducive to foaming, and price wants low, can be with are as follows: teletron glass (also known as CRT
Glass), plate glass, at least one of container glass.
Show in parts by weight by largely testing, auxiliary material glass is preferred are as follows: 25~30 parts of teletron glass；Or
30~35 parts of plate glass；Or 35~40 parts of container glass.Above-mentioned three kinds of glass can be such that useless bubble powder re-using sends out again
At foam glass.
Further, the low auxiliary material glass of the aluminum oxide content is preferred are as follows: teletron glass, teletron glass is in height
Viscosity when warm is lower, and the market price is also advantageously.
It should be noted that due to having been added the substances such as a certain proportion of foaming agent, fluxing agent in foam glass waste material,
When utilizing again using foam glass waste material as main material, need to consider the influence of these residuals, can not directly adopt with
Glass is the formula that raw material produces foam glass, need to be counted to the amount of foaming agent remaining in foam glass waste material, fluxing agent
It calculates, then calculates the content for needing need to additionally to add foaming agent and fluxing agent agent again.
Foaming agent includes carbon black, in parts by weight, preferably 0.20~0.30 part, further preferably 0.15~0.25
Part.
Fluxing agent can reduce blowing temperature, and suitable fluxing agent is introduced in foam glass waste material, and oxygen can be selected in fluxing agent
Change at least one of antimony and sodium sulphate.It is appreciated that otherwise the additional amount of fluxing agent suitably will will affect the strong of foam glass
Degree, preferably 0.10~0.70 part, further preferably 0.15~0.30 part.
In one of the embodiments, in parts by weight, the raw material of the foam glass includes: foam glass waste material: 65
~85 parts；Auxiliary material glass: 15~35 parts；Foaming agent: 0.20~0.30 part；Fluxing agent: 0.10~0.70 part.
In one of the embodiments, in parts by weight, the raw material of the foam glass includes: foam glass waste material: 70
~75 parts；Teletron glass: 25~30 parts；Foaming agent: 0.15~0.25 part；Fluxing agent: 0.15~0.30 part.
One embodiment of the invention also provides a kind of using foam glass waste material as the production method of the foam glass of main material, packet
Include following steps:
S1: each raw material is added in proportion and is uniformly mixed；
S2: each raw material of ball milling obtains powder and counts weight lower powder to diaphragm capsule；
S3: the foam glass is obtained through compression molding, foaming, annealing.
In step sl, each raw material is foam glass waste material, auxiliary material glass, foaming agent, fluxing agent, and in parts by weight,
Each raw material is added in proportion and is uniformly mixed.
It is further comprising the steps of before step S1: by foam glass waste material be broken into diameter 1mm particle below or
Powder.Specifically, waste leftover material is generated in foamed glass blank cutting process, to form foam glass waste material, directly uses skin
For band conveyer conveying foam glass waste material to crusher, foam glass waste material is broken into diameter 1mm particle below by crusher
Or powder, then boosted machine is transported to feed bin.
In step s 2, powder is obtained using each raw material of ball mill ball milling, the partial size of powder is big, then differential expansion, will form
The coarse foam glass of stomata；The partial size of powder is too small, although dilatancy is good, energy consumption is big, and it is uniform to be unfavorable for foaming agent
Distribution.Preferably, partial size of each raw material of foam glass after ball milling is 40 μm~70 μm.
In step s3, foam process is the committed step in foam glass production process, and heating rate is too fast, be will lead to
Pore opening in foam glass is uneven.Preferably, foam the temperature curve of temperature control process are as follows: with 25 DEG C/min~30 DEG C/min
Rate be warming up to 430 DEG C~460 DEG C, be then warming up to 680 DEG C~730 DEG C with 6 DEG C/min~8 DEG C/min rate, then with 2
DEG C/min~3 DEG C/min rate is warming up to 820 DEG C~900 DEG C, and constant temperature keeps completions in 40 minutes~60 minutes to foam.
In step s3, since the thermal coefficient of foam glass is small, annealing cool speed is usually relatively slow.Preferably, it anneals
The temperature curve of temperature control process are as follows: be cooled to 550 DEG C with 10 DEG C/min~15 DEG C/min rate, and keep 4h~5h, then with 1
DEG C/min~2 DEG C/min rate is cooled to 200 DEG C, and keeps 3h~5h, finally it is cooled to 1 DEG C/min~2 DEG C/min rate
Room temperature completes annealing.
