The specific embodiment
In the prior art, adopt dense acid-treated mode to reclaim the diamond of resin-diamond scroll saw, not only operating personnel self are damaged, and pollute the environment.As seen, existing way of recycling can't satisfy current environmental protection demand.The embodiment of the invention provides a kind of diamond recovery method for the resin-diamond scroll saw, and the diamond by on the physics mode recovery scroll saw efficiently solves the existing problem of prior art.The method comprises:
To resin-diamond scroll saw high-temperature process;
Resin-diamond scroll saw after the high-temperature process is placed the water of preset temperature, carry out quenching and process;
The resin-diamond scroll saw that is placed in the water is carried out ultrasonic processing, obtain the abrasive material material of resin-diamond scroll saw;
After described abrasive material material carried out Separation of Solid and Liquid, and carry out drying and process, obtain the solid mixture of described abrasive material material;
Described solid mixture is separated, obtain diamond particles.
In this programme, after the mode of employing high temperature, quenching reduces adhesive strength between the abrasive material on the resin-diamond scroll saw and the steel wire, mode by ultrasonic processing is carried out Separation of Solid and Liquid, drying, solid matter again and is separated, thereby obtain diamond particles so that abrasive material thoroughly separates with steel wire.In this programme, use the physical treatment modes such as high temperature, quenching, ultrasonic power, diamond particles is recycled, realized reclaiming by the environmental protection mode purpose of diamond particles.
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
The abrasive material of resin-diamond scroll saw is made of diamond, resin, filler, and wherein, described filler can be the silica that is used for improving adhesive property, aluminium oxide etc.The bonding force of the macromolecular material in the resin can be realized diamond is sticked on the scroll saw.In the steel wire schematic diagram and schematic cross-section of resin-diamond scroll saw as shown in Figure 1, the resin-diamond scroll saw is behind cutting silicon wafer, diamond 1 major part on the steel wire 4 of diamond fretsaw does not come off, just expose diamond 1 outside resin 3 and be extruded to the inside of abrasive material, so need by the mode of environmental protection diamond 1, filler 2, resin 3 to be separated, to obtain diamond particles.As shown in Figure 2, a kind of diamond recovery method for the resin-diamond scroll saw can comprise:
S101 is to resin-diamond scroll saw high-temperature process;
According to the macromolecular material characteristic of resin as can be known, when being higher than uniform temperature, the macromolecule network structure generation sex change in the resin, wherein, the oxide of a part of chain fracture, another part is emitted, and micropore and fragment appear in inside.This will cause resin material weightless, and then cause material embrittlement, and adhesive strength and hot strength reduce.Therefore, the resin-diamond scroll saw is carried out high-temperature process, can be so that the resin material sex change reduces adhesive strength, thereby carries out follow-up separating treatment.
Wherein, to resin-diamond scroll saw high-temperature process, be specifically as follows:
The resin-diamond scroll saw is positioned over carries out high-temperature process in the high temperature furnace.
According to resin and diamond characteristic, the temperature setting of high temperature furnace can be set to 450 ℃～550 ℃.And the resin-diamond scroll saw can be placed in the high temperature furnace and keep 25 minutes to 35 minutes.Be understandable that, above-mentioned temperature range, time range only are as a kind of example, should not consist of the restriction to the embodiment of the invention.In actual applications, can according to resin or the filler of difference batching, different high-temperature temperatures and high-temperature process time be set.
Need to prove, described high temperature furnace is for providing the high temperature furnace greater than the required temperature of resin sex change.For example: it can be Muffle furnace.Certainly, to resin-diamond scroll saw high-temperature process the time, also can utilize microwave or infrared ray etc.
S102 places the resin-diamond scroll saw after the high-temperature process in the water of preset temperature, carries out quenching and processes;
The resin-diamond scroll saw that will carry out after the high-temperature process is put into rapidly in the water of preset temperature, and quenching is processed.Wherein preset temperature can be determined according to actual conditions, and for example: it can be 15 ℃～35 ℃.Be understandable that, can stipulate voluntarily according to the water temperature of Various Seasonal, temperature is lower, and effect is better.
Because the linear expansion coefficient of steel wire and resin differs greatly, under the condition of large temperature difference quenching, most of resin bed can come off under the condition without external force naturally with steel wire.
S103 carries out ultrasonic processing to the resin-diamond scroll saw that is placed in the water, obtains the abrasive material material of resin-diamond scroll saw;
For under excessive temperature difference quenching conditions, the resin bed that the bonding force that does not separate with steel wire is stronger can be by carrying out ultrasonic processing to the cold water that is placed with the resin-diamond scroll saw, to realize the fully disengaging of tree resin bed and steel wire.And after ultrasonic processing, diamond, resin and filler can be dispersed in the cold water fully.
S104, described abrasive material material carried out Separation of Solid and Liquid after, and carry out drying and process, obtain the solid mixture of described abrasive material material;
When diamond, resin and filler are separated in the cold water fully, can carry out Separation of Solid and Liquid, carry out that then isolated mixture is carried out drying and process, obtain the solid mixture of abrasive material.Wherein, the mode of Separation of Solid and Liquid can be filtration, sedimentation, centrifugal etc.; The dry mode of processing can be freeze drying, pneumatic conveying drying, microwave drying etc.
S105 separates described solid mixture, obtains diamond particles.
Behind the solid mixture that obtains the abrasive material material, this solid mixture is carried out separating treatment, thereby obtain needed diamond particles.
Wherein, described solid mixture is separated, is specifically as follows:
Described solid mixture is carried out sizing.
Because the particle size of diamond particles, filler, resin is different, so can obtain by the mode of sizing described diamond particles.
Be understandable that, when solid mixture is separated, be not limited to particle size separation, can select according to the different qualities of each material in the solid mixture other separate mode.
As shown in Figure 3, through the recovery method that the embodiment of the invention provides, diamond 1, filler 2, resin (not shown) have broken away from steel wire 4 fully, therefore can realize the recovery of diamond particles.
The embodiment of the invention recycles diamond particles by using the physical treatment modes such as high temperature, quenching, ultrasonic power, has realized reclaiming by the environmental protection mode purpose of diamond particles.
The above only is the specific embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
