ʻO ka mea mua, hāʻawi i ke kumuhana i kahi hoʻolauna pōkole i ka aramid a me ka PE.
ʻO Aramid fiber lako Aramid, i ʻike ʻia ʻo Kevlar (ʻo ka inoa kemika ʻo phthalamide) i hānau ʻia i ka hopena o nā makahiki 1960.He ʻano hou ia o ka fiber synthetic kiʻekiʻe, nona ke kūpaʻa wela kiʻekiʻe, ka waikawa a me ke kūpaʻa alkali., ʻO ke kaumaha māmā, ka ikaika kiʻekiʻe a me nā mea maikaʻi ʻē aʻe, ua hoʻohana nui ʻia i nā lako pale pale-pale, ke kūkulu ʻana a me nā lako uila a me nā mea ʻē aʻe. nā māla.
Akā ʻelua mau hemahema o ka aramid:
1) E hoʻohaʻahaʻa ia i ka wā e hālāwai ai me nā kukuna ultraviolet;He maʻalahi ka hydrolyze, ʻoiai inā mālama ʻia ia i kahi maloʻo maloʻo, e hoʻomoʻo ia i ka wai ma ka lewa a me ka hydrolyze mālie.
No laila, ʻaʻole kūpono ka hoʻokomo ʻana i ka bulletproof aramid a me nā pale pale pale no ka hoʻohana lōʻihi ʻana i nā ultraviolet ikaika a me nā wahi humid, e hōʻemi loa i kā lākou hana pale a me ke ola lawelawe.Eia kekahi, ʻo ke kūpaʻa maikaʻi ʻole a me ke ola pōkole o ka aramid e kaupalena i ka hoʻohana hou ʻana o ka aramid ma ke kahua o ka bulletproof.
ʻOi aku ka kiʻekiʻe o ke kumukūʻai o ka aramid kiʻekiʻe ma mua o ka PE, ʻo ia paha ka 30% a 50% keu.I kēia manawa, ua emi mālie nā huahana pōkā e hoʻohana ana i ka aramid a hoʻomaka e pani ʻia e nā huahana pōkā PE.Inā ʻaʻole ia i loko o kahi kūlana kūikawā a i ʻole nā koi kūikawā, e like me ke kiʻekiʻe o ka wela o ka Middle East, pono ia e hoʻohana i nā lako pale pale PE.
1. ʻO ka PE i ʻōlelo ʻia ma mua ma ka PE fiber lako e pili ana i ka UHMW-PE, ʻo ia ka polyethylene kaumaha ultra-kiʻekiʻe.He fiber organik hana kiʻekiʻe ia i hoʻomohala ʻia i nā makahiki 1980 mua, a ua kapa ʻia ʻo ka honua i kēia lā me ka fiber carbon a me ka aramid.ʻEkolu mau mea ʻenehana kiʻekiʻe.ʻO nā ʻeke plastik i hoʻohana ʻia i ko mākou ola i kēlā me kēia lā, he mau huahana polyethylene maoli nō ia, he paʻa kiʻekiʻe loa a paʻakikī loa e hoʻohaʻahaʻa ʻia, kahi e hoʻohaumia ai i ke kaiapuni.Akā ʻo ia ma muli o kēia ʻano i lilo i mea kūpono no ka hana ʻana i nā pale kino.Eia kekahi, loaʻa iā ia nā hiʻohiʻona o ka haʻahaʻa haʻahaʻa haʻahaʻa, ka pale UV, a me ka pale wai.
Ma ke ʻano o ka pale ʻana i nā pōkā haʻahaʻa wikiwiki, ʻoi aku ka nui o ke kūpaʻa ballistic o ka UHMW-PE fiber ma kahi o 30% kiʻekiʻe ma mua o ka aramid fiber;
Ma ke ʻano o ka pale ʻana i nā pōkā kiʻekiʻe, ʻo ka hiki ʻana o ka pōkā o ka fiber UHMW-PE he 1.5 a 2 mau manawa o ka aramid fiber, no laila ʻike ʻia ʻo PE ʻo ia ka mea kiʻekiʻe kiʻekiʻe.
Eia nō naʻe, loaʻa i ka UHMW-PE kekahi mau hemahema: ʻoi aku ka liʻiliʻi o kona kūpaʻa kiʻekiʻe ma mua o ka aramid.Pono e ho'omalu'ia ka mahana ho'ohana o ka UHMWPE bulletproof i loko o 80 ° C (hiki ke ho'okō i nā koi wela o ke kino kanaka a me nā mea hana - ke kū'ē i ka mahana 55 ° C).Ke hoʻonui ʻia kēia mahana, e hāʻule koke kāna hana, a ke piʻi ka mahana i 150 ° C a ʻoi aku paha, heheʻe ia.Hiki i nā huahana bulletproof aramid ke mālama i kahi hoʻolālā paʻa a me ka hana pale maikaʻi i kahi kūlana wela kiʻekiʻe o 200 ℃.No laila, ʻaʻole kūpono nā huahana pōkā PE no ka hoʻohana ʻana i nā wahi wela kiʻekiʻe.
Eia kekahi, ʻaʻole maikaʻi ke kūpaʻa ʻana o ka PE e like me ka aramid, a ʻo nā mea hana e hoʻohana ana i ka PE e deform mālie ke hoʻokau ʻia i ke kaomi mau.No laila,ʻaʻole hiki ke hanaʻia nā mea hana e like me nā pāpale mahiole me nāʻano paʻakikī a pono e pale i ke kaomi no ka manawa lōʻihi.
Ma kahi o kēia mau hiʻohiʻona, ʻoi aku ka haʻahaʻa o ke kumukūʻai o ka PE ma mua o ka aramid e like me ka mea i ʻōlelo ʻia ma mua.
Ma keʻano laulā, loaʻa i ka PE a me ka aramid ko lākou mau pono a me nā hemahema.Eia naʻe, ʻoi aku ka nui o ka hoʻohana ʻana i kēia mau lā e hoʻohana i ka PE ma ke ʻano he pale pale.Pono nō e koho i nā lako pale pōkā i kūpono iā ʻoe e like me kou kūlana maoli.
