Laboratory Safety Knowledge 1. What is burning? What are the conditions for burning, fire prevention and fire extinguishing? Simply put, combustion is a violent chemical reaction that produces both light and heat. The three conditions for the combustion process are: 1) the presence of combustible su

Factors Affecting Rotational Viscometer Measurement of ViscosityRotational Viscometer - Temperature InfluenceThe effect of temperature change on the viscosity of the polymer solution is significant. The viscosity of the polymer solution decreases with the increase of temperature. The reason is that

Why Measure the Vapor Pressure of Petroleum Products?The vapor pressure of oil is one of the important indicators that indicate the evaporation performance, start-up performance, tendency of generating vapor resistance, and the amount of light distillate lost during storage.1. To Judge the volatilit

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.
