Minor Project
My research question is whether type
of amine curing agent is affecting curing temperature of epoxy system for
read-write head in hard disk drive (HDD). The amine curing agent is an
important component in epoxy adhesive because it induces the curing reaction
and continues to complete reaction. However, there are several types of amine curing agents and they affect the curing
temperature. Therefore, the amines are studied in order to formulate the epoxy
adhesive whose curing temperature is match with temperature of process in HDD
production.
Researchers who have looked at this
subject are Tanmoy Maity and Hongyang Cai. The former formulated epoxy adhesive
with aromatic amine and the latter used aliphatic amine as curing agent.
Maity et al (2007) reports
that the curing behavior of epoxy adhesive with aromatic amine curing agents is
investigated by differential scanning calorimetry (DSC) analysis. The curing
temperature is widely about 150 – 210oC.
Cai et al (2008) reports that
the DSC thermograms of aliphatic amine-epoxy systems show the curing
temperature about 115 – 125oC. This temperature is lower and
narrower than results of Maity because the structure of aliphatic amines is
more mobility than structure of aromatic amines at the same temperature.
Debate centers on the basic issue of
process temperature. The epoxy adhesive can be react if the temperature of
production is not less than curing temperature of epoxy system.
My work will be closer to the
research of Cai et al (2008) because the temperature of production is
120 – 130oC and the curing temperature of aliphatic amine-epoxy
systems is about 115 – 125oC. Moreover, the temperature of
production should not be more than 150oC because the read-write head
will be damaged at high temperature.
Finally, I expect my contribution
will be the way to choose and formulate the amine-epoxy systems whose the
curing reaction is appropriate for HDD production in order to increase the
productivity and especially reduce any problem during operation. (318 words)

ตอบลบMaity et al (2007) reports and Cai et al (2008) reports I think you should you 'reported'.
ตอบลบTHX U Krub!
ลบI will edit it :)
In the second paragraph, i think you should change "Tanmoy Maity and Hongyang Cai" to "Maity et al. and Cai et al." because they did not do this alone.
ตอบลบTHX U Krub!
ลบThey will not alone :'P
I think that references in APA style should be edit to...

THX U for your suggestion Krub :')
ลบI think "the structure of aliphatic amines is more..." should be "the structure of aliphatic amines was more..."
ตอบลบI'm not sure :)
THX U Krub!
ลบIt should be present tense because it's fact Krub :)
