Electronic Industry Standard of the People's Republic of China Determination method of viscosity of potassium silicate solution for electronics industry Potassium silicate solution for electronics industry-the methods of deiermination to viscosity【Main content and scope of application】This standard specifies the determination method of liquid density, but is not applicable to the determination of viscosity of silicate solution for electronics industry. Principle
SJ/T 10227—97
The resistance to the potential applied in the threading liquid is proportional to the torsion of the spring of the meter when the rotation is about the same as the rotation. This meter indicates the effectiveness of the instrument. The 3-axis meter
2. 1 is in the rotation type meter. The actual value of
5.3 is 6. ℃,
4 Determination step
will be the grinding acid wave, for example, into the mutual diameter of "70n" will be in the case of the need for the group of instruments in the constant loss device. The heart number turned the table car right connection, through the full, let the liquid and the rotor wave surface mark machine, the box liquid extreme control at 2 =. Work, turn the visual, select the turn Di hair 3/, open the electric hole to identify the turn in the prisoner can turn 2, install the indicator dig rod, turn off the motor, then the wrong needle stopped at the dense, read the agricultural not less than three 5 internal sensitivity value, liquid its level letter inquiry. 5th
