Aramid fiber

Aramid eriri a na-akpọ polybenzoylenediamine, na carbon fiber, ultra-high molecular arọ polyethylene eriri na ụwa atọ isi elu-arụmọrụ eriri, dịtụ obere njupụta, elu ike, elu modulus, elu okpomọkụ na-eguzogide, corrosion iguzogide, mkpuchi, bụ ọtụtụ-eji na agha, aerospace, electronic ngwa, njem, ewu, ọgwụ na ndị ọzọ ubi. Aramid fiber bụ eriri polyamide synthetic aromatic, nke emere site na polymer linear sịntetik (opekata mpe 85% nke njikọ amide jikọtara ya na mgbanaka aromatic abụọ) nke mejupụtara amide bond interconnecting aromatic ring (Ar-CONH-Ar). Isi yinye bụ mgbanaka aromatic na njikọ amide, na usoro mgbanaka aromatic siri ike. A na-agbatị ụdọ polymer ka ọ bụrụ ihe owuwu dị ka mkpanaka.

N'otu oge ahụ, usoro ahịrị ahịrị nke yinye molekụla na-eme ka ọnụọgụ oghere nke aramid dị elu, yabụ olu otu ahụ nwere ike ịnabata polymer ọzọ, yabụ ike dị elu. Dị iche na ụdọ ụrọ molekụla polymer na-agbanwe agbanwe, usoro ihe eji arụ ọrụ nke eriri para-aramid bụ nke ihe mejupụtara mkpanaka yiri mkpanaka nke mgbanaka benzene mebere. N'ihi ọnụnọ nke nnukwu mgbanaka benzene conjugated, akụkụ ahụ yinye molekụla siri ike ịtụgharị n'ime, ya mere ọ na-enye usoro siri ike kwụ ọtọ.
