Breaking fiber material samples using a flux-structured grinder in Dingyuan TL2010S
Breaking fiber material samples using a flux-structured grinder in Dingyuan TL2010S FOSHAN PHARMA CO., LTD. , https://www.fs-pharma.com
In this issue, we will share with you the grinding of fiber materials.
Guest:
Hello everyone, the case I want to share with you this time is a relatively new case. The sample should be a class that has not been shared before. It belongs to the material science, and contains fiber materials. The instrument used is Dingyuan TL2010S. Flux organizes the grinder. Let's give you a few pictures below.
Guest:
This case mainly grinds the above three samples. The carbon fiber material used in this time is mainly used by military enterprises for aerospace materials. It seems to be a crunchy sample. In fact, the fiber-containing samples have certain toughness. It is more difficult than general tissue grinding, just like the experience of teachers in our group grinding animal tissue, or tough plant seed rhizomes or seeds. Therefore, one of the purposes of this case is to test the toughness of the sample, and then carry out the experiment of component analysis.
Guest:
In the specific experimental process, the 15ml grinding tank equipped with the flux microstructure grinder in Dingyuanyuan TL2010S was used, 1 8mm steel ball, 2000rpm, grinding time 90s. After groping through such conditions, the effect of grinding is better and meets the experimental needs.
Guest:
Send a picture of the grinding results below, which is more intuitive.
Guest:
Among them, when using a flux-structured grinder in the Dingyuan TL2010S, the carbon fiber sample was set to two cycles in accordance with the above polishing setting conditions, and the others were all one cycle. It can be seen that all three samples have been ground into powder, and the overall experiment is relatively successful. If you have any questions, please feel free to ask.
user:
Is this grinding and its samples useful in medicine? Maybe the problem is a little bit of a dish.
Guest:
This problem is quite good. Generally speaking, as long as it is not a particularly large amount, it can be ground to see which type of experiment you are doing next. The amount of samples at the laboratory level is particularly large, that is, it is necessary to carry out preliminary pulverization into small pieces, such as Chinese medicine decoction pieces.
user:
What about chemical drugs?
Guest:
For example, if you want to do chemical composition analysis, or you need to use experimental animals such as mice, do drug metabolism, the experimental animal's heart, liver, spleen, lung and kidney, etc. need to be ground before the next step of mass spectrometry.
user:
Oh, that application is quite wide.
Guest:
Yes, the tissue grinder is a pre-processing instrument for the sample and is required for many experiments.
user:
Oh, I am engaged in chemical drug synthesis, the next work will be in contact with pharmacological preparations, etc., the problem is pediatrics, see forgiveness.
Guest:
How come, we should. You are professional here, you can also share with us the instruments you are interested in, and we can share them if we have any.
user:
Good, learn slowly.
Guest:
Thank you for your support!
user:
This grinding effect is very good, need liquid nitrogen to cool down?
Guest:
Grinding with liquid nitrogen is better.
user:
Is there a good number of smashed data? Does it meet the requirements for superfine pulverization?
Guest:
The customer does not have too specific requirements for the pulverized sample, so that it can be micron-sized, too fine to analyze the components.
Guest:
The customer's request is 5um. After grinding, it meets the basic needs of customers. The amount of grinding of each customer can be as long as the sample and the beads are not more than two-thirds of the whole. Their materials do not require high grinding temperature.
user:
Animals, heart and liver, these parenchymal organs are good, the conventional parameters will do, but the skeletal muscles are so bad to grind, the steel balls are embedded in the inside and then rotate together. Our method is to use small scissors to cut in advance and select some larger steel balls. , grinding twice, the protein concentration is quite high, do not know other people's programs?
Guest:
Yes, your method is quite good. The sample and tumor you are talking about, as well as the valved heart organ, are similar grinding methods. Generally, we have to set up 2-3 cycles, or you can try the combination of large steel ball and small steel ball.
