Aramida Fiber

ʻO ka fiber Aramid i kapa ʻia he polybenzoylenediamine, a me ka pulupulu kalapona, ultra-high molecular weight polyethylene fiber a me ka honua nui ekolu kiʻekiʻe-performance fiber, liʻiliʻi liʻiliʻi, ikaika kiʻekiʻe, modulus kiʻekiʻe, kiʻekiʻe wela kūʻē, corrosion kūʻē, insulation, ua hoʻohana nui ʻia i loko. pūʻali koa, aerospace, nā mea uila, ka lawe ʻana, ke kūkulu ʻana, ka lāʻau lapaʻau a me nā mea ʻē aʻe. ʻO ka fiber Aramid kahi fiber polyamide aromatic synthetic, i hana ʻia me kahi polymer linear synthetic (ma ka liʻiliʻi o 85% o ka paʻa amide e pili pono ana i ʻelua apo ʻala) i haku ʻia me ka amide bond interconnecting aromatic apo (Ar-CONH-Ar). Hoʻokumu ʻia ke kaulahao nui me ke apo ʻala a me ka paʻa amide, a paʻa ke ʻano o ke apo ʻala. Hoʻopili ʻia ke kaulahao polymer e hana i kahi ʻano like me ke koʻokoʻo.

I ka manawa like, ʻo ka laina laina o ke kaulahao molecular e hoʻonui i ka nui o ka hoʻohana ʻana i ka nui o ka aramid fiber space, no laila hiki i ka nui o ka hui ke hoʻokomo i ka polymer, no laila ʻoi aku ka ikaika. ʻOkoʻa mai nā kaulahao molekula polymer maʻamau, ʻo ke kaulahao nui o ka para-aramid fiber ka mea nui i haku ʻia me ke koʻokoʻo-like molecular structure i hana ʻia e ke apo benzene. Ma muli o ka loaʻa ʻana o ke apo benzene conjugated nui, paʻakikī ka ʻāpana kaulahao molekala i loko, no laila ke hōʻike nei ia i kahi ʻano paʻa laina.
