Do int taf id-differenza bejn kinematiku viskożità u viskożità indiċi?

Kinimetiku viskożità is an importanti indikatur għal kejl il fluwidità ta' żejt prodotti. Simply put, the larger the value, the higher the viscosity; The smaller the value, the lower the viscosity, the lower the viscosity. This value vary with temperature. When the temperature the viscosity decreases; When the temperature is low, the viscosity is high.
Kif is the kinematic viscosity measured? It's actually quite simple, just put a certain amount of oil into a calibrated viscometer and measure the time it take for it it flow through the viscometer at a certain temperature. Multiplying this time by the calibration constant of the viscometer yields the value of kinematic viscosity. The formula is as follows: v=C * t, Where v is the kinematic viscosity (in mm ²/s), C is the calibration constant (in mm ²/s ²), and t is the process time (in seconds).
X'inhu is il viskożità indiċi? In fact, it jirrappreżenta il grad għal li the oil changes with temperature. The higher the viscosity index, the less affected the viscosity of the oil is by temperature, li means that the viscosity of the viscosity of the oil is less sensitive to temperature and can maintain a stable viscosity. Dan index can be measured by detection equipment, normalment by knowing the kinematic viscosity values of the oil at 40 degree and 100 degree , and calculating it skon skon li skon il-formula in GB/T 1995 standard.
Il ogħla il viskożità indiċi , il aħjar il viskożità temperatura karatteristiċi ta ' il- lubrikanti żejt , li għal xi wħud firxa jindika il - aħjar kwalità ta ' iż-żejt So, lubrikant manifatturi se tħallas speċjali attenzjoni lil dan indikatur matul il- produzzjoni proċess. Skont differenti viskożità indiċijiet, lubrikazzjoni żejt in Ċina is maqsum f' erba' livelli: 40-80 is the intermedju viskożità indiċi 80 is l avvanzat viskożità indiċi 120 is a ħafna għoli viskożità indiċi indiċi 140 is il ultra-għoli viskożità indiċi.
