In the chemical, coating, paint, food and other industries, viscosity is a very important parameter, which directly affects the quality and performance of the product. As a commonly used fluid viscosity testing instrument, the QNB type Viscosity Cup plays a vital role. This article will deeply discuss the principle, structure, usage and application of QNB type Viscosity Cup in industrial production.
Principle and structure
The QNB type Viscosity Cup is an instrument that relies on the speed of the liquid passing through the pipe under the action of gravity to measure the viscosity of the fluid. It mainly consists of a cup body, a stand, a base and a timer. The cup is usually conical in shape, with a small hole at the bottom. The liquid flows out of the small hole, and the viscosity of the liquid is measured indirectly through the flow rate. The bracket is used to fix the Viscosity Cup to ensure stability during testing. A timer or speed measuring instrument is usually installed on the base to record the time or speed of liquid outflow.
Instructions
The use of QNB type Viscosity Cup is relatively simple. Clean the Viscosity Cup and the liquid to be measured, and make sure the base of the Viscosity Cup is stable. Pour the liquid to be measured into the Viscosity Cup. Note that the liquid level should be slightly higher than the mouth of the cup, and wait for the liquid surface to calm down. Start timing when the liquid flows out of the orifice and record the flow time or use a timer to record the flow time. Based on the outflow time or flow rate and the calibration data of the Viscosity Cup, the viscosity value of the liquid is calculated.
Application areas
QNB type Viscosity Cups are widely used in various industrial fields and can be used to measure the viscosity of various liquids, such as resins, glues, coatings, etc., and to control product quality during the production process. It is used to measure the viscosity of paints, coatings, etc. to adjust the formula and production process to ensure the uniformity and smoothness of the coating. It is used to measure the viscosity of various liquids in food, such as jam, soy sauce, sauces, etc., to ensure the taste and quality of the product. It is used to measure the viscosity of medicines such as liquid medicines and ointments to ensure the stability and efficacy of the medicines. Used to measure the viscosity of cosmetics, lotions and other products, adjust product formulas, and improve product quality.
With the continuous advancement of science and technology, viscosity testing technology is also constantly developing, and new viscosity testing instruments are constantly emerging. However, the QNB type Viscosity Cup is still widely used in many industries due to its simplicity, ease of use and low cost. In the future, with the continuous development of industrial production and the increasing demand, the QNB type Viscosity Cup will continue to play its important role and gradually realize intelligence and automation to meet the viscosity testing needs of different industries.
In short, the QNB type Viscosity Cup, as an important fluid viscosity testing instrument, provides reliable technical support for product quality control and production process improvement in various industries. Its simplicity, ease of use and low cost give it broad application prospects and development space in industrial production.
