how to confirm amorphous copolymer by dsc
@microlabtesting
@microlabtesting 7 ай бұрын
Hi, for amorphous polymers you should be seeing multiple glass transition regions during the heating/cooling cycle. You can look up the data sheets to see which polymer has glass transition at that temperature or you can do an FTIR analysis to check for the peaks and find out the polymers. You can watch the FTIR video in our channel to learn more

@@mediwise2474 ​ with DSC, you will be able to find out the glass transition temperature. Combine this with FTIR, you can find the family of polymer ex. PC-ABS will have two dips in the DSC indicating 2 glass transitions, and in FTIR curve you can see peaks that are characteristic to these 2 materials.

Hey man! thanks for the video. I have a question about the dimension. Should we use B557 to determine an aluminum specimen dimensions instead of ASTM E8 or can we also use ASTME8? Another question is in ASTM E8 as you know there is a table saying Plate type, 40 mm Wide specimen and gives us the standard dimensions for 40mm wide as gauge lenght is 200.0 mm and Width is 40.0 mm and goes like this, so my second question is are those dimensions in the ASTM E8 is the dimensions that WE MUST use or can we also choose different dimensions from them? Ive choosen 35 mm width, 80 mm gauge lenght, 13 mm radius, 5 mm thickness and 50 mm lenght of the grip section for stainless steel specimen and carbon steel specimen do you think those are good for a specimen? And can i use the same dimensions for Aluminum specimen? I would be highly appreciated if you could answer! Thank you!

Hey man! Since it is an Aluminium sample the governing spec will be ASTM B557. You can go with a Gauge length of 50mm and width of 12.5mm if your material thickness is less than 19mm, which is only 5mm in your case (refer to the sheet-type specimen). Note 3 in B557 allows for smaller widths although not recommended. In the end the gauge length can be modified as long as the elongation % result is not required and your Uts, yield strength values should be ok.

hi sir, you subjected the material to a sander, does that damage the Cr coating on the material, the chromium will depele indicating a wrong reading, i am really not entirely sure, please correct me if i am wrong

Hi, so Cr will usually be in the form of an alloying element in which case it does not easily come out of the metal through grinding. On the other hand, elements from the abrading wheel may fall on the sample and may give high value if Al (when using Alumina wheel). So this must always be cleaned using acetone. For Chromium coatings, it is not advisable to do this testing for the reasons you mentioned. Other methods like ED XRF or wet chemistry can be done.

Unless you own a well and get your water from the well that is drilled on your property your water is contaminated would most likely sodium fluoride which is a severe chemical that will eat through metal and concrete and glass and everything it is a contaminant that is put in the water supply because the government's too lazy to dispose of it properly

Thank you John for the comment. Absolutely, Flouride definitely will increase the corrosion rate of TMT bars. Also, depending on the area you are in, you are also bound to find the trace elements coming from fertilisers used on the crops being washed into the water bed.

why we stretch the specimen in both way even we can just simple hold one side and just stretch otherside?

Hi Yechang, that’s a good question. Typically one side is held fixed and the other crosshead alone will be moving.
