A: Vocal problems, like polyps, are not restricted to singers. While singers require peak performance of their voice, other voice professionals, such as teachers, lawyers, clergy, salespeople and receptionists, are also at higher risk for many vocal cord problems.
The permissible operating temperature range of nitrile rubber is â40 to +100 Â°C (â40 to +210 Â°F). For brief periods, temperatures of up to 120 Â°C (250 Â°F) can be tolerated. SKF also offers a special nitrile rubber compound with a temperature range between â55 and +110 Â°C (â65 and +230 Â°F).
The melting point of solder depends upon its particular formulation. In the case of eutectic tin-lead solder, the melting temperature is somewhere around 360 degrees Fahrenheit. The temperature becomes a bit higher with different formulations of solder, such as 60/40 tin lead, which may be 10 degrees higher.Higher temperatures can also be expected for lead-free versions of solder, and that may change the temperature at which youâd want to use for your soldering iron.he temperature becomes a bit higher with different formulations of solder, such as 60/40 tin lead, which may be 10 degrees higher.
