The history of the rotary viscometer

The rotational viscosity measurement method pioneered by the Brookfield family in the United States uses its unique relationship between the shear and resistance generated by the rotor and the fluid to obtain a brand-new viscosity value, creating a precedent for the measurement of dynamic viscosity. The Brookfield family designed a dynamic viscosity measuring instrument in the world under the name of its own family, that is, a rotational viscosity measuring instrument, which is today's Brookfield viscometer. And Brinell is also a shorthand for the Brookfield family.

Dyne pen test principle

Dyne pen test principle Using the surface tension test pen, it is easy to analyze the surface ability, hydrophilicity, wettability and other small changes of different solids. The analysis method is simple and effective, and the accurate result can be quickly known by only scratching a mark on the surface of the substrate. This is specially designed for production line testing and is carried out by trained operators in the factory. During the test, an intermediate value should be selected as the starting point, such as 38mN/m. During the test, if the test pen wets the surface of the substrate within 2 seconds, the surface tension of the substrate is greater than the selected value or just right, then you need to select A test pen with a larger value is used for the second test, and so on, until the test result is reduced to a water droplet (spherical) within 2 seconds, the previous value of this test is regarded as the surface energy of the substrate. And use this for comparative analysis.

Common faults of punching machine

Common malfunctions 1. The punch can't come up after hitting it: 1. Adjust the air pressure to 4-5KG\GM 2. Adjust the punch of the punching machine to a suitable position, so that the punch of the punching machine is lowered. 2. There are burrs or can't be knocked out: 1. Grind the lower mold for about five or six minutes with a gold steel set, and then use a whetstone for two to three minutes. 3. The plastic bag will be broken when punching: 1. Check whether the air pressure is low 2. Check whether the punching signal system is normal 3. Check whether the punching machine and the cutter are synchronized 4. Whether the residence time of the punching machine is too long, intermittently unable to punch the hole or sometimes it is good and bad: 1. Check whether the air pressure is low 2. Is the air volume insufficient? 3. Check whether the solenoid valve has water or the muffler is blocked 4. Check whether the cylinder is leaking
