Abstract
The invention discloses a secondary recycling method of silicon rod slicing waste mortar. The method comprises the following steps: (S01) firstly, waste mortar generated by slicing a silicon rod is extracted and filtered; (S02) all components of the filtered waste mortar are renewedly mixed to reach a component scale value of new mortar; and the density of the waste mortar is guaranteed to reach the density needed by slicing the silicon rod; (S03) a filter screen is added in a cutting chamber mortar circulating port of a silicon rod cutting machine; and the waste mortar is filled in a cutting chamber; and (S04) when the silicon rod is cut, a silicon rod cutting process is adjusted to guarantee the silicon rod slicing quality. The secondary recycling method of the silicon rod slice waste mortar has such advantages as convenience for operation, reduction of slicing accessory consumption and reduction of production cost.
Description
Technical field
The present invention relates generally to silicon rod cutting technique field, refers in particular to a kind of silicon rod slicing waste and old mortar secondary cycle Application way.
Background technology
Need to use mortar when silicon rod cuts at present, and use mortar to carry out at present after cutting completes, mortar directly can be done and scrap process, thus considerably increase the consumption of cutting auxiliary material.
Summary of the invention
The technical problem to be solved in the present invention is just: for prior art exist technical problem, the invention provides a kind of easy and simple to handle, reduce cutting supplementary product onsumption silicon rod slicing waste and old mortar secondary cycle Application way.
For solving the problems of the technologies described above, the technical scheme that the present invention proposes is:
A kind of silicon rod slicing waste and old mortar secondary cycle Application way, comprises the following steps:
Waste and old mortar after S01, first extraction silicon rod slicing, and it is filtered;
S02, each component ratio of waste and old mortar after filtering to be prepared again, to reach the component ratio value of new mortar, and density required when ensureing that the density of waste and old mortar reaches silicon rod slicing;
S03, cutting chamber mortar circulation port place in silicon rod cutting machine set up screen pack, and are loaded in cutting chamber by waste and old mortar;
S04, carry out silicon rod cutting time, adjustment silicon rod cutting technique to ensure the quality of silicon rod slicing.
Further improvement as technique scheme:
In step S04, the cutting technique of adjustment is specially and increases cutting tension force and strengthen mortar injection flow.
In step S03, be new screen pack by the old filter screen replacement of the mortar jar in silicon rod cutting machine, the order number of new screen pack is greater than the order number of old screen pack.
The order number of described new screen pack is 800 ~ 1000 orders.
In step S01, by using 100 ~ 200 object filter bags, waste and old mortar is filtered.
Compared with prior art, the invention has the advantages that:
Silicon rod slicing of the present invention waste and old mortar secondary cycle Application way, by filtering waste and old mortar, redistribution to be to reach component ratio and the density of new mortar, and to setting up screen pack in cutting machine and more renewing screen pack, and corresponding adjustment cutting technique, thus ensure the quality of waste and old mortar cutting silicon wafer, and method of the present invention is easy and simple to handle, makes waste and old mortar carry out secondary utilization, reduce the consumption of cutting auxiliary material, reduce production cost.
Accompanying drawing explanation
Fig. 1 is method flow diagram of the present invention.
Detailed description of the invention
Below in conjunction with Figure of description and specific embodiment, the invention will be further described.
As shown in Figure 1, the silicon rod slicing waste and old mortar secondary cycle Application way of the present embodiment, comprises the following steps:
Waste and old mortar after S01, first extraction silicon rod slicing, and it is filtered, to filter out the broken silicon wafers and other bulky grain and impurity that produce in cutting process;
S02, each component ratio of waste and old mortar after filtering to be prepared again, to reach the component ratio value of new mortar, and density required when ensureing that the density of waste and old mortar reaches silicon rod slicing;
S03, cutting chamber mortar circulation port place in silicon rod cutting machine set up screen pack, to filter waste and old mortar further, and are loaded in cutting chamber by waste and old mortar;
S04, carry out silicon rod cutting time, adjustment silicon rod cutting technique to ensure the quality of silicon rod slicing.
Silicon rod slicing of the present invention waste and old mortar secondary cycle Application way, by filtering waste and old mortar, redistribution to be to reach component ratio and the density of new mortar, and to setting up screen pack in cutting machine and more renewing screen pack, and corresponding adjustment cutting technique, thus ensure the quality of waste and old mortar cutting silicon wafer, and method of the present invention is easy and simple to handle, makes waste and old mortar carry out secondary utilization, reduce the consumption of cutting auxiliary material, reduce production cost.
In the present embodiment, mortar is made up of carborundum and ethylene glycol, ethylene glycol: the ratio of carborundum is 1:0.95, and specifically add carborundum or ethylene glycol according to the density detected, while ensureing its ratio, density is 1.635 ~ 1.650Kg/m
2.
In the present embodiment, in step S04, the cutting technique of adjustment is specially and increases cutting tension force and strengthen mortar injection flow, to ensure the requirement that silicon chip cuts.
In the present embodiment, in step S03, be new screen pack by the old filter screen replacement of the mortar jar in silicon rod cutting machine, the order number of new screen pack is greater than the order number of old screen pack.Wherein the order number of new screen pack is 800 ~ 1000 orders, improves filter effect further.
In the present embodiment, in step S01, by using 100 ~ 200 object filter bags, waste and old mortar is filtered.
When concrete operations, extract silicon chip cutting use after waste and old mortar, the use amount of every cylinder mortar is about 280L ~ 300L, and the mortar after extraction uses 150 object filter bags to filter out broken silicon wafers and large particle and impurity; Then again adjustment is prepared to the waste and old mortar after filtration, inside mortar a mixing bowl, add the carborundum of 50Kg ~ 60Kg(1500#) fresh sand allocate, stir, use density tester to carry out slurry density test in allocation process, reach the slurry density 1.635 ~ 1.650Kg/m of section instructions for use
2, then add stainless steel filter screen at slicer cutting chamber mortar circulation port place, 50 orders will be respectively in mortar jar and 150 object double-layer filtering nets change individual layer 800 object screen pack into; Adjust slicer technological parameter, important technological parameters changes cutting tension force into 23N by original 21N, and flow changes 100L/min into by original 90L/min, with the cutting power of stable mortar, ensures the quality of section.
Below be only the preferred embodiment of the present invention, protection scope of the present invention be not only confined to above-described embodiment, all technical schemes belonged under thinking of the present invention all belong to protection scope of the present invention.It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, should be considered as protection scope of the present invention.
