I-Aramid Fiber

I-Aramid fiber ibizwa nge-polybenzoylenediamine, kanye ne-carbon fibre, i-ultra-high molecular weight polyethylene fiber kanye nemicu emithathu emikhulu yomhlaba esebenza kahle kakhulu, ukuminyana okuncane, amandla aphezulu, i-modulus ephezulu, ukumelana nokushisa okuphezulu, ukumelana nokugqwala, ukugquma, isetshenziswa kabanzi ezempi, i-aerospace, izinto zikagesi, ezokuthutha, ezokwakha, ezokwelashwa neminye imikhakha. I-Aramid fiber iyifayibha yokwenziwa ye-polyamide enephunga elimnandi, eyenziwe nge-polymer eqondile yokwenziwa (okungenani u-85% we-amide bond ixhunywe ngokuqondile namasongo amabili anephunga elimnandi) eyakhiwe yi-amide bond exhuma indandatho enamakha (Ar-CONH-Ar). Iketango eliyinhloko lakhiwe indandatho enamakha kanye nebhondi ye-amide, futhi ukwakheka kwendandatho enephunga elimnandi kuqinile. Iketango le-polymer leluliwe ukuze lenze isakhiwo esifana nenduku.

Ngesikhathi esifanayo, ukwakheka komugqa weketango lamangqamuzana kwenza izinga lokusebenzisa indawo ye-aramid fibre libe phezulu, ngakho-ke umthamo weyunithi ungamukela i-polymer eyengeziwe, ngakho amandla aphezulu. Ihlukile kumaketanga emolekyuli e-polymer evamile aguquguqukayo, ukwakheka kweketango eliyinhloko le-para-aramid fiber ikakhulukazi lakhiwe isakhiwo samangqamuzana esifana nenduku esakhiwe indandatho ye-benzene. Ngenxa yokuba khona kweringi ye-benzene enkulu ehlanganisiwe, ingxenye yeketango lamangqamuzana kunzima ukuyijikeleza ngaphakathi, ngakho-ke iveza umugqa oqinile oqinile.
