Q1: What is a viscometer?
A1: A viscometer is an instrument used to measure the viscosity of fluids (liquids and gases). Viscosity is a physical quantity that indicates the internal friction within the fluid when the fluid is flowing. It is the ability of the fluid to resist deformation. It is an important indicator used to identify some finished or semi-finished products. Viscosity varies from fluid to fluid and varies with temperature. There are mainly three types of capillary viscometers, rotational viscometers and falling ball viscometers.
Q2: What is the definition of viscosity?
A2: When a liquid is flowing, the property of internal friction between its molecules is called the viscosity of the liquid. The viscosity of the liquid is expressed by viscosity, which is a resistance factor used to characterize the properties of the liquid. The viscosity of insulating oil is the same as the viscosity of general liquid, that is, the internal friction of the liquid, that is, when the insulating oil moves relative to laminar flow under the action of external force. The properties of insulating oil molecules that generate internal frictional resistance. The greater the internal friction of the insulating oil, the greater the viscosity, the more difficult the flow, and the poorer heat dissipation performance.
Q3: What is a viscometer used for?
A3: Viscosity is an important physical parameter used to measure the ability of liquids to resist flow. Using a viscometer to measure the viscosity of a liquid is an important means of industrial process control, improving product quality, and saving and developing energy. It is closely related to the fields of petroleum, chemical, electric power, metallurgy and national defense. Status plays an important role.
Tips: What is the function of viscometer?
Viscosity is an important physical parameter that measures the resistance of liquids to flow. For example, for lubricating oil, viscosity is an important indicator for evaluating its lubricating ability. When the lubricating oil passes through the lubricated moving surface, the local high temperature and high pressure will oxidize the lubricating oil. At the same time, the addition of various impurities will also reduce the fluidity of lubricating oil, resulting in an increase in viscosity. Therefore, the measurement of lubricating oil viscosity can reflect the quality status and remaining life of lubricating oil.
Viscometer’s application field is not only in the chemical industry such as adhesives, coatings, lubricants, but also in the daily chemical industry such as toothpaste and shampoo. In addition, the viscometer is also widely used in food fields such as yogurt, honey, ketchup, fruit juice and beverages. In the production process, a viscometer is often used to detect the viscosity of the product, so as to control the viscosity of the product. Viscometers are indispensable tools in production and product development. SISCO digital rotational viscometer is stable and reliable in quality, high in accuracy and good in repeatability. With the help of a viscometer, the product can be controlled within the appropriate viscosity range to give full play to its performance.
