What is the oxidation stability of petroleum products and the importance of testingThe ability of petroleum products to resist permanent changes in their properties caused by the action of air (or oxygen) is called the oxidation stability of petroleum products. The anti-oxidation stability of lubric

Four Ball Tester and Four Ball Testing MethodAbrasion resistance test of oil (four-ball test):The PB value is also the maximum non-jamming load and is a typical indicator of the anti-wear performance of lubricants. The PD value is an extreme pressure performance index, and ZMZ is called the comprehe

The residual carbon value of an oil product refers to the mass percentage of the oil product's carbon residue formed after the evaporation and thermal cracking process under a specific high temperature condition. The value of residual carbon is related to the chemical composition and ash content of

What should be paid attention to when doing viscosity test1. When the viscosity is measured, the test temperature is different, and the constant temperature time is also different; The sample for measuring the viscosity must first be dehydrated and filtered of mechanical impurities

Automated Houillon Viscometer

The main specifications that determine the quality of fuel oil include viscosity (Viscosity), sulfur content (Sulfur Content), and pour point (Pour Point).Viscosity is the most important performance index of fuel oil and the main basis for classifying fuel oil.

What is softening point of bitumen? Under the conditions of the ring and ball method, the temperature at which the bitumen is softened by heating, deformed under the specified weight of the steel ball and dropped to a lower deck with a distance of 25.4 mm, is called the softening point of bitumen.

Five Commonly Used Methods for Measuring the Surface Tension of LiquidsIntroduction:The force acting on the surface of the liquid to reduce the surface area of the liquid is called the surface tension of the liquid.

What is the ductility of bitumen? Softening Point of Bitumen Penetration Test of Bitumen Ductility Test of Bitumen

In order to judge and compare the quality of the fuel and make a reasonable selection, some performance indicators are specified for the fuel.1. Indexes that affect fuel combustion performance: cetane number (cetane number); diesel index (Diesel index); distillation range (distillation range); calor
