I. use

This instrument is mainly used to determine the kinematic viscosity of Newton's or approximate Newton's fluid paint. It can also be used as a comparative measurement. Applicable viscosity in 30s ~ 100s coating product measurement, is a portable viscometer, that is measured liquid filled, from the hole out of the time required to measure the viscosity of the liquid, in seconds.

 
Two, principle

The viscosity of a LND-1 viscometer is a condition viscosity, that is, the amount of time that a certain amount of sample flows out of the hole at the specified aperture at a given temperature, expressed in seconds. Using the following formula, the flow time (S) of the sample can be converted to kinematic viscosity (mm2/s).

Among them, Gamma = (t-6.0) /0.223 (30s = t = 100s)

T - outflow time (s)

Y - kinematic viscosity (mm2/s)


Three, the main technical characteristics

The viscosity cup is made of brass and has a capacity of about 100 ml. Its geometrical size and inner wall roughness conform to the requirements of the GB/T1723 coating viscosity method. Its bottom is made out of stainless steel.

Correction factor K value, that is, in the set temperature conditions (such as 20 degrees Celsius + 0.1 degrees), with two standard oil filled viscosity cup, flow finished

The viscosity cup placed in a cup with a ring on the global level, adjust the level of the base screw the blister center, undertake cup capacity of about 150 ml, for a solution for.

Four. Brief introduction of structural description
