ʻO ka hoʻohana ʻana i ka lole fiber aramid i nā huahana bulletproof

ʻO ke olonā ʻAramidaHe fiber synthetic hana kiʻekiʻe, me ka ikaika kiʻekiʻe loa, modulus kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa waikawa a me ka alkali, māmā, a me nā ʻano maikaʻi ʻē aʻe. Hiki i kona ikaika ke piʻi i 5-6 mau manawa o ka uea kila, ʻo ka modulus he 2-3 mau manawa o ka uea kila a i ʻole ke aniani fiber, ʻo ka paʻakikī he 2 mau manawa o ka uea kila, a ʻo ke kaumaha he 1/5 wale nō o ka uea kila. I ke kiʻekiʻe o ka mahana o 560 ℃, hiki i nā fibers aramid ke noho paʻa, ʻaʻole e pala, a ʻaʻole hoʻi e heheʻe. Eia kekahi, he maikaʻi kona insulation a me nā waiwai anti-aging, a he ola lawelawe lōʻihi. I kēia manawa, hoʻohana pinepine ʻia nā lako bulletproof mainstream (e like me nā vests bulletproof, a me nā mahiole bulletproof).nā lole olonā aramidI waena o lākou, ʻo ka lole maʻemaʻe fiber aramid haʻahaʻa-umekaumaha kekahi o nā mea nui i ke kahua o ka pale ʻana i nā pōkā. Ke hoʻohālikelike ʻia me nā pālule nylon kuʻuna a me nā mahiole kila, ʻo nā pālule pale ʻōkā a me nā mahiole me nā olonā aramid i hoʻohui ʻia ʻaʻole wale nō i liʻiliʻi a māmā akā he 40% ʻoi aku ka maikaʻi o ka pale ʻana i nā pōkā.

Hiki ke hoʻomaopopo ʻia ke kumumanaʻo hana o nā ʻaʻahu pale pōkā ma kēia ʻano: ke pā ka pōkā i ka papa lole o ka ʻaʻahu, hoʻoulu ʻia nā nalu haʻalulu a me nā nalu hoʻoluhi a puni ke kiko o ka hopena. Ma o ka hoʻolaha wikiwiki ʻana a me ka hoʻolaha ʻana o ka fiber, hiki i kēia mau nalu ke lele i loko o kahi nui o nā fibers, a laila ma kahi ākea e omo i ka ikehu o ka nalu haʻalulu. ʻO kēia omo ikehu nui e hōʻemi pono i ka hopena o nā pōkā ma ke kino o ke kanaka, a laila e ʻike ana i ka hopena pale o nā ʻaʻahu pale pōkā.

Mea pale pōkā a me kāna hana maikaʻi loa

ʻO ke kumu o nā ʻaʻahu pale pōkā aia i loko o nā mea fiber ikaika kiʻekiʻe a lākou e hoʻohana ai, ʻo ia hoʻi nā fiber para-aramid, i ʻike ʻia hoʻi he mau fiber polyamide para-aromatic, he mea pale pōkā i mahalo nui ʻia. ʻO kona ʻano kemika symmetrical kiʻekiʻe e hāʻawi i ke kaulahao molekala i ka paʻakikī maikaʻi loa, e hoʻolilo ana iā ia i ʻokoʻa loa mai nā polymers kaulahao maʻalahi maʻamau ma ke ʻano o ka solubility, nā waiwai rheological, a me ka hana ʻana.

Ua kaulana nā olonā Para-aramid no ko lākou mau waiwai kino a me nā ʻano mīkini maikaʻi loa, me ka ikaika kiʻekiʻe loa, ka modulus kiʻekiʻe, a me ka māmā. ʻO ko lākou ikaika kikoʻī he ʻelima a ʻeono manawa ke kiʻekiʻe ma mua o ke uea kila maʻamau, a ʻoi aku ko lākou modulus kikoʻī ma mua o ke uea kila ma kahi o ʻelua a ʻekolu. Eia kekahi, hōʻike nā olonā i nā waiwai wela maikaʻi loa, me ke kūpaʻa wela kiʻekiʻe, ka hoʻonui haʻahaʻa, a me ka conductivity wela haʻahaʻa, a ʻaʻole e puhi a heheʻe paha. Ua kapa ʻia hoʻi nā olonā Para-aramid he "nā olonā pale bullet" ma muli o ko lākou insulation maikaʻi, kūpaʻa i ka palaho, a me ke kūpaʻa ʻana i ka ʻelemakule.

Nā Noi a me nā Manaʻolana o Para-ʻAramida fiber

ʻO ke olonā para-aramid, kahi mea nui i ka ʻoihana pale kaua a me ka pūʻali koa, ua hoʻohana nui ʻia ma ka honua holoʻokoʻa. Wahi a nā helu helu, ʻoi aku ka nui o ka aramid i nā olonā pale ma ʻAmelika Hui Pū ʻIa ma mua o 50% a me 10% ma Iapana. ʻO kona mau ʻano māmā e hana ai i nā ʻaʻahu pale pōkā aramid a me nā mahiole, hiki ke hoʻomaikaʻi nui i ka hiki ke pane wikiwiki o ka pūʻali koa. Eia kekahi, hoʻohana nui ʻia ka para-aramid i nā kaʻa, nā kelepona, nā aerospace, a me nā haʻuki waho ma muli o kāna hana maikaʻi loa.
