Discussion Overview
The discussion revolves around the challenges of creating a lubrication mixture using paraffin wax, paraffin oil, and xylene. Participants explore the formulation and properties of the mixture, including the behavior of the wax as it cools and the effectiveness of different solvents.
Discussion Character
- Technical explanation
- Debate/contested
- Experimental/applied
Main Points Raised
- One participant describes a mixture of 1/3 melted paraffin wax, 1/3 paraffin oil, and 1/3 xylene, noting that it turns into a soft paste upon cooling.
- Another participant suggests that the amount of wax is too high for the amount of solvent used, referencing a patent that indicates a maximum solubility of paraffin in xylene at a specific temperature.
- A participant inquires whether the base oil should also be kept at 7.8 grams and considers using hexane instead of xylene.
- It is proposed that hexane may work better than xylene, with cyclohexane suggested as an even better option, while noting the need for heating to achieve proper dissolution.
- One participant explains the intended use of the lubrication for chains, emphasizing the need for the wax to coat effectively without becoming crumbly.
- Another participant suggests that low ambient temperature may be causing the wax to solidify too quickly and recommends warming the mixture before use.
- There is a discussion about the terminology of "paraffin oil," with some participants asserting that it is a misnomer for kerosene, while others provide links to clarify its usage.
- A suggestion is made to reduce the amount of oil used and consider using a resin for better adhesion, along with a recommendation for microcrystalline wax.
Areas of Agreement / Disagreement
Participants express differing opinions on the formulation and terminology, with no consensus reached regarding the optimal mixture or the definition of "paraffin oil." The discussion remains unresolved with multiple competing views on the best approach.
Contextual Notes
Participants highlight the importance of temperature in the dissolution process and the potential limitations of the current formulation, but no specific mathematical or experimental steps are resolved.
