Fluxes that are active at room temperature
WebPhotosynthetic photon flux density (PPFD): the number of photons in the 400- to 700-nm waveband incident per unit time on a unit surface. Suggested units: μmol cm −2 s −1. • Photosynthetic irradiance (PI): the radiant energy in the 400- to 700-nm waveband incident per unit on a unit surface. Suggested units: W m −2. • WebRosin fluxes are inactive at room temperatures but become active when heated to soldering temperatures. They are naturally acidic (165 to 170 mg KOH per g equivalent). They are soluble in a variety of solvents but not water. This is the reason for using solvents, semiaqueous solvents or water with saponifiers to remove them.
