How does the viscosity index of the lubricating oil be calculated?

How does the viscosity index of the lubricating oil be calculated?

Abstract: The viscosity index indicates the degree to which all fluid viscosity varies with temperature. The higher the viscosity index, the smaller the effect of fluid viscosity on the temperature, the less sensitive the viscosity to the temperature.

IVS400 Viscometer

According to the different viscosity index, the lubricating oil can be divided into three grades: 35-80 for the medium viscosity index lubricants; 80-110 for the high viscosity index lubricants; 110 above the special high viscosity index lubricants. Viscosity index of 100-170 in the oil, high-grade multi-grade lubricants, it has a viscosity curve changes smooth and good viscosity temperature. At lower temperatures, the polymer molecules in these viscosity index improvers have little solubility in the oil and the molecules are curled into small clusters, so that the viscosity of the oil increases little; and at high temperatures it is in the oil The viscosity increases, and the curly-like linear molecules expand and elongate, so that the viscosity increases greatly, making up the viscosity of the base oil due to the temperature rise. So the higher the viscosity index, the smaller the viscosity changes with temperature.

Calculation of Viscosity Index

Viscosity index should be calculated using the formula, the viscosity index of less than 100 and higher than 100 are uses different formula. ASTM D2270 method is divided into two parts, one for the A method, another one for the B method. A method is actually ASTM D567 old method, the use of calculation method to determine the viscosity index. The B rule is intended for use with fuels with a viscosity index greater than 100.

Viscosity index (Viscosity index) formula A:

Viscosity index between 0 to 100 between the use of this formula. The formula is: viscosity index

VI = [(L-U) / (L-H)] * 100

H = viscosity of 100 known oil at 100 ° F (or 40 ° C), but its viscosity at 210 ° F should be the same as the viscosity of the unknown oil at 210 ° F (or 100 ° C). Because of its high viscosity index, so the H (High) alphabet.

L = viscosity of the known oil at 100 ° F (or 40 ° C). But its viscosity at 210 ° F (or 100 ° C) should be the same as the viscosity of the unknown oil at 210 ° F (or 100 ° C). Because of its low viscosity index, so the L (Low) alphabet.

U = unknown viscosity index of the raw material at 100 ° F (or 40 ° C).

Viscosity index (Viscosity index) algorithm B:

Specially used to calculate the viscosity index of more than 100 for the use of oil.

IVS800 Viscometer

If a result of an oil calculated by the old method is more than 100, it must be recalculated in this way and calculated as a result of the B method. And expressed as VI (E), VI (Extended), VIe, or "epitaxial viscosity index". The formula is as follows:

(N) = [(Antilog N) -1 / 0.0075] 100 where N = the viscosity of the oil sample at 210 ° F, which is equal to the desired index at the ratio of H and U at 100 ° F. which is

N = (㏒H-㏒U) / (㏒KV210), or

KV210N = H / U

KV210 = kinetic viscosity of oil sample at 210 ° F (or 100 ° C) (KV is abbreviation for Kinemetic Viscosity)

H = A known oil having a viscosity index of 100 is obtained by the A method, its kinematic viscosity at 100 ° F (or 40 ° C) (which can be determined by the 24th table)

U = the kinematic viscosity of the oil sample at 100 ° F (or 40 ° C) (where H> U)

Application of Hangzhou Zhongwang's Viscometer in Polymer, Plastics, Rubber and Other Fields

Application of Hangzhou Zhongwang's Viscometer in Polymer, Plastics, Rubber and Other Fields

Polymer material characterization is an important field of polymer science. From the initial aggregation, laboratory analysis, prediction of processability, and then to predict end-use performance, and the impact of material degradation on the environment, polymer characterization is an important way for us to understand or predict material properties throughout the life cycle process.

Hangzhou Zhongwang Technology CO.,LTD of Ubbelohde viscosity automatic measurement equipment can quickly measure the kinematic viscosity, dynamic viscosity, Concentrated viscosity, intrinsic viscosity, relative viscosity, polymer molecular weight, rheological properties and other information. The software integrates almost all of the viscous calculation formulas, and the experimenter does not need to do it manually.

Application of polymer recycling:

Recycling may cause changes in polymer properties. For example, shearing and heating can cause degradation; the addition will weaken the material properties. Therefore, the quality control of recycled materials is of great importance to the target application of these materials. The automatic viscosity measurement system of Hangzhou Zhongwang Technology Co.,ltd can measure the intrinsic viscosity and viscosity average molecular weight of the recovered polymer.
