capacitance change is the viscosity of the tested sample, which is shown by the instrument.
Rotary viscometer has the advantages of convenient use, stable performance and simple maintenance. It is suitable for measuring the viscosity of various fluids such as greases, paints, inks, coatings, plasticslurry, rubber, latex, detergents, resins, condensed milk, cream, drugs, cosmetics and other fluids. It is a necessary instrument for textiles, chemical industry, petroleum, electromechanical, medicine, food, light industry, construction and other industries, as well as laboratories and analytical laboratories of colleges and universities, scientific research institutions and military industry departments.
After the rotary viscometer is turned on, zero bits should be detected first. This operation is generally carried out without installing a rotor, and then the inner cylinder with a radius R2 is installed coaxially in the outer cylinder of the radius of R1, which is full of viscous fluids. The synchronous motor rotates at a stable speed, connects the scale disk, and then drives the inner cylinder (i.e. the rotor) to rotate through the wire and the rotating shaft. The inner cylinder (i.e.e. the rotor) is affected by the viscous based on the fluid. The greater the effect, the torque generated by the filament is counterbalanced with it, so the greater the scale indicated by the needle on the dial. Multiply the reading by a specific coefficient to obtain the dynamic viscosity of the liquid.
Vibrating viscometer: This viscometer works by a fluid when an object in the fluid vibrates.Obstructive effectThe size of this action is related to the viscosity of the fluid. Commonly usedVibration viscometerThere is an ultrasonic viscometer, and there is a shrapnel in the detector. When excited by pulsed current, the shrapnel generates mechanical vibration in the ultrasonic range. When playingWhen the sheet is immersed in the tested sample, the amplitude of the shrapnel is related to the viscosity and density of the sample. In the case of known density, the viscosity value can be obtained from the measured amplitude data.Motion viscosity tester is a kind of vibration viscometer, which generally displays viscosity values by digital display.
By type of measured product:
Tin paste viscometer: The tin paste viscometer adopts the coaxial double cylindrical rotary viscometer of the spiral pump sensor, which is mainly used to measure tin paste, film thick adhesive paste, adhesives, solder paste anti-welding paint, liquid anti-welding paints, other inks, viscose pastes, etc. According to the sealing of the measurement department, I have temperature adjustment skills, be able to connect to a personal computer, automatically measure, and read data for automatic calculation.
Portable viscometer: The portable viscometer adopts a coaxial double cylindrical type. The screw line sliding pump sensor maintains the fixed flow. The viscosity of the viscosity can be correctly measured according to the change of the connection stirring viscosity.
Viscosity controller: The viscosity controller can well manage the viscosity of various fluids such as coatings, ink, adhesives, food, drugs, oils, etc.; it adopts a coaxial double cylindrical type; the screw line sliding pump sensor maintains the fixed flow, and a stable value can be obtained; the viscosity of the continuous viscosity can be correctly measured according to the change of stirring viscosity.
Stormer viscometer: Stormer viscometer is a test instrument used to measure paint and other KU values to represent paint viscosity. The instrument is designed according to the ASTM standard and GB9269-88 standard. Tianjin Precision Materials Testing Machine Factory is the largest enterprise specializing in the production of paint, coating, ink equipment material testing machine and special laboratory equipment for the coating industry. This viscometer adopts a single-chip microcomputer. The operator can directly read the KU value of the measured sample from this instrument without checking the table.
Working principle: Immerse the slurry rotor into the tested sample, increase and decrease the weight weight to maintain the rotation speed of the slurry leaf rotor at 200 rpm, and replace the weight of the sample under test at 200 rpm to the viscosity KU value through a single-chip microcomputer.
