Aramid Fiber

Aramid fiber ake kira polybenzoylenediamine, da carbon fiber, matsananci-high kwayoyin nauyi polyethylene fiber da duniya uku manyan high-yi fiber, in mun gwada da kananan yawa, high ƙarfi, high modules, high zafin jiki juriya, lalata juriya, rufi, da aka yadu amfani a cikin. soja, sararin samaniya, na'urorin lantarki, sufuri, gine-gine, likitanci da sauran fannoni. Aramid fiber ne na roba aromatic polyamide fiber, wanda aka yi da roba mikakke polymer (akalla 85% na amide bond an haɗa kai tsaye zuwa biyu aromatic zobe) hada da amide bond interconnecting aromatic zobe (Ar-CONH-Ar). Babban sarkar yana kunshe da zoben aromatic da haɗin kai na amide, kuma tsarin zoben ƙamshi yana da ƙarfi. An shimfiɗa sarkar polymer don samar da tsari mai kama da sanda.

A lokaci guda, tsarin layin layi na sarkar kwayoyin halitta yana sa adadin amfani da sararin fiber na aramid ya yi girma, don haka ƙarar naúrar zai iya ɗaukar ƙarin polymer, don haka ƙarfin ya fi girma. Daban-daban da sarƙoƙi na yau da kullun na polymer masu sassaucin ra'ayi, babban tsarin sarkar fiber na para-aramid galibi ya ƙunshi tsarin ƙwayoyin sanda kamar sanda wanda zoben benzene ya yi. Saboda kasancewar babban zoben benzene mai haɗaɗɗiya, sashin sarkar kwayoyin yana da wahalar juyawa a ciki, don haka yana gabatar da tsayayyen tsari mai tsayi.
