A mixer is a mechanical device that utilizes mechanical force and gravity to evenly mix two or more materials. During the mixing process, the contact surface area of the material can also be increased to promote chemical reactions; It can also accelerate physical changes.
Discharging method: The powder material adopts a pneumatic large door structure, which has the advantages of fast unloading and no residue; High fineness materials or semi fluid materials use manual or pneumatic butterfly valves. Manual butterfly valves are economical and applicable, and pneumatic butterfly valves have good sealing performance for semi fluid, but their cost is higher than manual butterfly valves. In situations where the mixer requires heating or cooling, a jacket can be configured.
There are two heating methods for the mixer: electric heating and thermal oil heating: electric heating is convenient, but the heating speed is slow and the energy consumption is high; The heating of heat transfer oil requires the configuration of an oil pot, oil guiding power, and pipelines, which requires a large investment, but the heating speed is fast and the energy consumption is low. The cooling process can directly inject cooling water into the jacket, which has a large heat exchange area and fast cooling speed. The motor is directly connected to the mixing spindle through a cycloidal pinwheel reducer, with a simple structure, high operating stability, and convenient maintenance.
Sometimes, the tablet press may experience cracking problems, so why is this?
It turns out that when the tablet press presses the tablet, the upper and lower pressure of the tablet is relatively high, and the magnitude of the pressure is related to the elastic recovery rate of the tablet. The elastic recovery rate of the upper and lower surfaces of the tablet is relatively high, and the upper surface of the tablet is moved out of the mold hole first, so it is more likely to crack first.
The Scientific Design Department can prevent the occurrence of cracking in the tablet press. How to increase the plasticity of excipients and the formability of particles, and adding compressible starch during the process can solve the above problems.
The possibility of cracking during the compression process of the tablet press is also low, and the recovery rate is also low. As the compression time increases, the plasticity also increases. This can prevent the phenomenon of cracking, and the amount of water in the particles can shape the plasticity of the particles, improve the distribution of pressure, and prevent the phenomenon of cracking. Adding a good amount of lubricant can also change the pressure distribution and prevent cracking.
Factory staff need to effectively solve the occasional cracking problem of the tablet press in order to better maintain the image of the product and increase consumer trust.
Powder coating is a new type of solvent free 100% solid powder coating. It has two main categories: thermoplastic powder coatings and thermosetting powder coatings. The coating is made by mixing special resins, pigments and fillers, curing agents, and other additives in a certain proportion, and then preparing it through processes such as hot extrusion, crushing, and sieving. They are stored stably at room temperature, subjected to electrostatic spraying or fluidized bed immersion coating, and then heated, baked, melted, and solidified to form a flat and bright coating film, achieving the purpose of decoration and corrosion prevention.
