1.Ukuhlukaniswa kwe-Aramid Fibers
Imicu ye-Aramid ingahlukaniswa ibe izinhlobo ezimbili eziyinhloko ngokuvumelana nezakhiwo zayo zamakhemikhali ezihlukene: uhlobo olulodwa lubonakala ngokumelana nokushisa, i-meso-aramid e-flame retardant, eyaziwa ngokuthi i-poly(p-toluene-m-toluoyl-m-toluamide), efushanisiwe njenge-PMTA, eyaziwa ngokuthi i-Nomex e-US, ne-Aramid 1313 e-China; kanti olunye uhlobo lubonakala ngokuba namandla aphezulu, imodulus enwebekayo ephezulu, nokumelana nokushisa, okwaziwa ngokuthi i-poly(p-phenylene terephthalamide), efushanisiwe ngokuthi i-PPTA, eyaziwa ngokuthi i-Kevlar e-US, i-Technora e-Japan, i-Twaron e-Netherlands, i-Tevlon e-Russia, ne-Tevlon e-China. I-P-phenylenediamine, efushanisiwe njenge-PPTA, igama lokuhweba lase-United States le-Kevlar, i-Japan ye-Technora, i-Netherlands ye-Twaron, i-Russia ye-Tevlon, i-China ebizwa ngokuthi i-aramid 1414.

I-Aramid fiberiwuhlobo oluphezulu lokushisa olungazweli, olunamandla amakhulu, imodeli ye-high-elastic yezinhlobo zemicu, kokubili izakhiwo zemishini zemicu ye-inorganic kanye nemicu ephilayo, ukusebenza kokucubungula, ukuminyana kanye nemicu ye-polyester kuyaqhathaniswa. Ngesikhathi esifanayo futhi inokumelana okuhle kakhulu kwamakhemikhali, ukumelana nemisebe, ukumelana nokukhathala, ukuzinza kwe-dimensional nezinye izakhiwo ezinhle kanye ne-rubber resin enezindawo ezithile zokunamathela. Njengamanje umkhiqizo unezinhlobo ezimbili ze-pulp ne-fiber. Yiba i-aerospace, irabha, imboni ye-resin, okokusebenza kwe-elekthronikhi nekagesi, ezokuthutha, izinto zezemidlalo kanye nokwakhiwa komphakathi nezinye izindawo zezinto ezintsha. Ikakhulukazi ngokulungiselelwa kwefayibha ye-aramid yezinto ezihlanganisiwe zephepha le-aramid ezisebenza kakhulu zingasetshenziswa kabanzi njengezinto zokufaka ugesi ezisezingeni eliphezulu, amabhodi wesekethe aphrintiwe nezinto zokuvikela igagasi kagesi nokunye okubhekwa kakhulu.

2. I-Aramid FiberI-Morphology
I-1414 fiber iphuzi ngokugqamile, i-1313 fiber imhlophe qwa. Ngokulandelana ngemicu emifushane (noma i-filament) ne-pulp fiber (noma i-precipitation fiber) amafomu amabili efayibha. I-Filament isetshenziswa kakhulu ezindwangu, irabha nakweminye imikhakha, imboni yephepha isebenzisa i-staple fiber kanye ne-pulp fiber.
