So that the method can be applied to municipal road surfaces, the material can also be used as building material for bridge and house construction.
When the glass pumice is applied to pavement, the porosity is 15% -25%, the water permeability is high, the burden of urban drainage facilities can be lightened when precipitation is concentrated, and the pavement ponding is prevented. Especially in recent years, along with the occurrence of urban waterlogging and other problems, a design concept of a sponge city is provided, and after a large amount of glass pumice is applied, the sponge city with the functions of seepage, stagnation, storage, purification, use, drainage and the like can be built by combining a gap structure between the glass pumice and a microporosity structure of the glass pumice so as to effectively solve the urban waterlogging phenomenon. For this reason, the glass pumice stone is used as the filler for road paving, and the conventional glass pumice stone can meet the general road surface bearing requirement, but for special road sections needing to pass large heavy-duty engineering vehicles, the strength of the conventional glass pumice stone can not meet the requirement, so that the strength of the glass pumice stone needs to be improved.
When the glass pumice is applied to bridges and houses, the glass pumice is applied as an interlayer, and the effects of weight reduction, load improvement, energy conservation and heat preservation can be realized by utilizing the light and micro-pore structures of the glass pumice, but the same safety consideration requires the glass pumice to have higher strength so as to realize the performance which is not input into the conventional building materials, and the glass pumice also needs better heat preservation effect for the application of wall building materials.
In view of the foregoing, there is a need for a method of making glass that can improve the strength and thermal insulation properties of glass pumice.

The high-strength closed-cell glass pumice can be obtained through the following two typical proportioning and implementation processes.
Embodiment one:

s1, mixing: putting the raw materials into a stirrer for stirring and mixing uniformly;
the weight ratio of the raw materials is as follows:
glass powder, 90%;
marble powder, 5%;
limestone, 5%;
s2, feeding: in order to ensure the adverse effect caused by the existence of large-particle raw materials in the closed pore forming process, screening by using a vibrating screen, namely, introducing the mixed raw materials in the step S1 into the vibrating screen for screening, wherein the screen is 300 meshes; the vibrating screen is positioned above the feeding end of the conveyor belt of the sintering furnace, two isolation strips perpendicular to the running direction of the vibrating screen are arranged on the conveyor belt, the height of each isolation strip is 20mm, a baffle strip is arranged at the feeding port of the sintering furnace and perpendicular to the running direction of the conveyor belt, the bottom of each baffle strip is in sliding contact with each isolation strip (namely, the ground clearance height of the bottom of each baffle strip is equal to the ground clearance height of the top of each isolation strip), and the raw materials screened in the vibrating screen enter the conveyor belt, and enter the sintering furnace along with the conveyor belt, and the stacking height of the raw materials is not higher than 20mm through the cooperation of the isolation strips and the baffle strips;
meanwhile, a collecting box (the width of the collecting box is larger than that of the conveying belt) is arranged below the feeding end of the conveying belt, and the bottom of the collecting box is communicated with the stirrer in S1 by taking a screw conveyor as a lifting mechanism, so that raw materials falling to two sides of the conveying belt by sweeping through a baffle strip can be recycled
S3, sintering: sequentially passing through a preheating temperature rising area, a foaming sintering area and an annealing area in a sintering furnace to obtain glass pumice with a closed-pore structure;
wherein the temperature of the preheating heating area is 780 ℃ and the duration time is 30min;
the temperature of the foaming sintering area is 800+/-5 ℃ and the duration time is 10min;

compared with the conventional process flows of a preheating zone, a heating zone and a foaming sintering zone, the process flow integrates and improves the temperature and time of the preheating heating zone, glass powder starts to melt at 790-800 ℃, so that the glass powder can be in a high Wen Linjie state before melting starts by improving the temperature and time of the preheating heating zone, and then the glass powder is in a molten state at 10 ℃ in a shorter time when the foaming sintering zone is performed, so that carbon dioxide bubbles generated in a short time of calcium carbonate and magnesium are not broken, a large number of closed cell structures are formed, and the process flow of an annealing zone is added to avoid that the open cell structures are formed by local cracking of the closed cell structures due to irregular cracking of glass pumice caused by the drastic decrease of the temperature of direct air cooling, so that the duty ratio of the closed cell structures can be effectively increased by reducing the temperature change of the annealing process;
preferably, a secondary annealing zone is further arranged behind the annealing zone, the temperature of the annealing zone is 500 ℃, the duration time is 15-20 min, and the dramatic intensity of temperature change is further reduced, so that the closed-cell structure of the closed-cell glass pumice is firmer.
S4, cooling: and (5) paving the sintered glass pumice on a cooling table, and cooling to room temperature.
The compressive strength of the glass pumice stone prepared by the process can reach two to four times of that of an open pore structure through test detection, so that the compressive capacity of the glass pumice stone is greatly improved, and the glass pumice stone has higher bearing capacity when being applied to paving pavements and building materials; meanwhile, the closed pore structure further improves the heat insulation capacity, and is beneficial to having better heat insulation effect when being used as a wall heat insulation layer. Through test detection: the strength of the closed-cell glass pumice J1 manufactured by the process is 1MP (namely 10 kg per centimeter), the strength of J2 is 3MP, and the strength of J3 is 5MP (which is close to the hardness of red bricks and 7,5MP of red bricks), thereby being capable of perfectly replacing conventional building materials and having the functions of light weight and heat preservation.
