Protective leaching cups, systems, and methods of use
In an embodiment, a protective leaching cup may include a base portion, at least one sidewall defining an opening general opposite the base portion, and a receiving space in communication with the opening and at least partially defined by the base portion and the sidewall. The receiving space is sized and configured to receive at least a portion of the superabrasive element. A seal contact portion is located on an inner surface of the sidewall. The seal contact portion is configured to form a seal against the superabrasive element that is at least partially impermeable to fluid(s). At least one of the seal contact portion or the sidewall includes material(s) exhibiting a flexural modulus greater than about 150,000 psi at room temperature.
1. A protective leaching cup, comprising:
a base portion;
at least one sidewall extending from the base portion and defining an opening generally opposite the base portion, the at least one sidewall including an inner surface;
a receiving space in communication with the opening, the receiving space at least partially defined by the base portion and the inner surface, the receiving space sized and configured to receive at least a portion of a superabrasive element;
a seal contact portion extending from the inner surface of the at least one sidewall, the seal contact portion configured to form a seal against the superabrasive element that is at least partially impermeable to one or more fluids, the seal contact portion exhibiting a rounded cross-sectional shape; and
wherein at least one of the seal contact portion or the at least one sidewall includes one or more materials exhibiting a flexural modulus greater than about 150,000 psi at room temperature.
2. The protective leaching cup of claim 1 , wherein at least one of the seal portion or the at least one sidewall includes one or more materials exhibiting a heat deflection temperature greater than about 190° F. under no load.
3. The protective leaching cup of claim 1 , wherein the one or more materials include at least one of polypropylene or a fluoropolymer.
4. The protective leaching cup of claim 1 , wherein the flexural modulus is about 150,000 psi to 250,000 psi at room temperature.
5. The protective leaching cup of claim 1 , wherein the flexural modulus is about 200,000 psi to about 315,000 psi at room temperature.
6. The protective leaching cup of claim 1 , wherein the flexural modulus is about 150,000 psi to 350,000 psi at room temperature.
7. The protective leaching cup of claim 1 , wherein the heat deflection temperature is greater than about 250° F. under no load.
8. The protective leaching cup of claim 1 , wherein the heat deflection temperature is greater than about 300° F. under no load.
9. The protective leaching cup of claim 1 , wherein the heat deflection temperature is about 190° F. to about 350° F.
10. The protective leaching cup of claim 1 , wherein the seal contact portion comprises a ring-like portion protruding into the receiving space from a portion of the inner surface of the at least one sidewall.
11. The protective leaching cup of claim 1 , wherein the seal contact portion exhibits a generally semi-elliptical cross-sectional shape.
12. The protective leaching cup of claim 1 , wherein the seal contact portion includes an inner diameter that is about 0.1 inches to about 0.3 inches less than an outer diameter of the superabrasive element.
13. The protective leaching cup of claim 1 , further comprising an outer cup surrounding at least a portion of the base portion or the at least one sidewall.
14. The protective leaching cup of claim 12 , wherein the outer cup includes polypropylene.
15. The protective leaching cup of claim 1 , wherein the superabrasive element is interference fitted with the seal contact portion.
16. The protective leaching cup of claim 1 , wherein the seal contact portion is sized and positioned on the at least one sidewall to seal against a superabrasive side surface of the superabrasive element while not contacting a substrate side surface of the superabrasive element.
17. A protective leaching system, comprising:
one or more protective leaching cups, at least one of the one or more protective leaching cups including:
a base portion;
at least one sidewall extending from the base portion and defining an opening generally opposite the base portion, the at least one sidewall including an inner surface;
a receiving space in communication with the opening, the receiving space at least partially defined by the base portion and the inner surface, the receiving space sized and configured to receive at least a portion of a superabrasive element;
a seal contact portion extending from the inner surface of the at least one sidewall and exhibiting a rounded cross-sectional shape, the seal contact portion configured to form a seal against the superabrasive element that is at least partially impermeable to one or more fluids,
a leaching tray including:
a tray body having a plurality of receptacles formed therein, each of the plurality of receptacles configured to receive one of the one or more protective leaching cups; and
wherein at least one of the one or more protective leaching cups or the leaching tray includes one or more materials exhibiting a flexural modulus greater than about 150,000 psi at room temperature.
18. The protective leaching system of claim 17 , wherein at least one of the one or more protective leaching cups or the leaching tray include one or more materials exhibiting a heat deflection temperature greater than about 190° F. under no load.
19. The protective leaching system of claim 17 , wherein the protective leaching cup includes polypropylene.
20. The protective leaching system of claim 17 , wherein the leaching tray includes at least one of polypropylene or a fluoropolymer.
21. The protective leaching system of claim 17 , wherein at least one of the one or more protective leaching cups is interference fitted with the tray body.
