In our laboratory, the mixer, the dispersing machine is a necessary equipment for mixing materials, especially the material needs to be completed, such as: dispersion, homogenization, emulsification, dissolution, solid-liquid mixing, etc., ordinary mixing obvious force, and scattered Machine will be able to show their talents. Laboratory Disperser is also called emulsifier, homogenizer, homogenizer, etc. In fact, FLUKO company from China to promote this device, it has been defined on its scientific name: high shear dispersion emulsifier. The high speed of the line produced during the speed of the material has been treated from the traditional macro-mixing into a higher micro-mix. How many people will use such equipment in the end?
1, the material level of the height of the head to be more than the head of the head, below the liquid level, the sleeve will not get liquid lubrication, dry grinding, resulting in rapid damage.
2, the powder mixture, you should first add the liquid phase in the beaker, start the disperser, then add the powder, the powder can be brought into contact with the liquid phase was quickly into the working cavity part, was quickly dispersed, to avoid Gelatinization and agglomeration.
3, the speed adjustment should be low to high, in the closure of the dispersion machine, the need to first adjust the speed to the minimum speed.
4, FLUKO disperser can be equipped with more than 20 kinds of work head, different work head corresponding to different process requirements, the choice must first clear the experimental process requirements, and then select the exact work head
5, if the material temperature is higher than 120 ℃, should be replaced before the experiment copper alloy sleeve, so that the standard sleeve by the impact of high temperature lead to deformation.
6, poor mobility or high viscosity of the material, it is recommended to choose two teeth of the rotor, more effectively reduce the resistance caused by the material, the rapid completion of the experiment.
7, the working head of the dispersion machine into the beaker to work, it is recommended eccentric placement, can effectively improve the material handling effect, increase the shear probability.
8, after the use of dispersing machine, the need to use special tools to work on the head of the stator part of the open cleaning, and then dry back in place, so that the remaining material affected the next experimental results.
The basic structure of the dispersing machine is composed of electric motor, dispersing impeller and ingredient tank.
Motor: The motor of the disperser can rotate the spindle by speed.
Dispersed impeller: Dispersion machine below the spindle has a dispersed impeller, through the rotation of the spindle can drive the high-speed rotation of the impeller, and the material mixed and decentralized.
The dispersed impeller under the dispersion axis is a serrated impeller. In the impeller on the circumference of the upper and lower staggered bend into a zigzag type,Laboratory Disperser the tilt angle and tangential direction of 20 ° ~ 40 °, the impeller rotation of each tooth when the edge of the edge can produce a strong impact. The outer edge of the tooth promotes the outward flow of objects to form a cycle and shear force.
High-speed dispersion of the nose: can be used by hydraulic lifting control, and can be around the column to do 180 ° ~ 360 ° rotation.
During the dispersion process, part of the material near the sawtooth is accelerated to throw out, part of the internal slowdown over the edge of the teeth to strengthen the role of shear, the paint cycle to the jagged near, continue to be accelerated and slippery, under the action of viscosity is dispersed,Laboratory Disperser The teeth between the serrations can form air turbidity to increase the dispersion of the pigment particles.
Ingredients: is a tool used to install the dispersion material.
