Ifayibha yeAramidi-high-performance synthetic fiber, inamandla aphezulu, i-modulus ephezulu, ukumelana nobushushu obuphezulu, ukuxhathisa kwe-asidi kunye ne-alkali, i-lightweight, kunye nezinye iimpawu ezibalaseleyo. Amandla alo anokuba ngama-5-6 amaxesha e-wire wire, i-modulus ngamaxesha angama-2-3 yocingo lwensimbi okanye i-fiber yeglasi, ukuqina kuphindwe kabini kunocingo lwensimbi, kwaye ubunzima buyi-1/5 kuphela yocingo lwensimbi. Kubushushu obuphezulu be-560 ℃, iifiber ze-aramid zinokuhlala zizinzile, zingaboli, kwaye azinyibiliki. Ukongeza, ine-insulation elungileyo kunye ne-anti-aging properties, kunye nobomi benkonzo ende. Okwangoku, izixhobo zokuthintela iimbumbulu eziqhelekileyo (ezifana neevesti zokuthintela iimbumbulu, nezigcina-ntloko ezikhusela iimbumbulu) ziqhele ukusetyenziswa.ilaphu ifayibha aramid. Phakathi kwabo, i-low-gravity aramid fiber plain fabric enye yezinto eziphambili kwintsimi ye-bulletproofing. Xa kuthelekiswa nehempe zangaphantsi zenayiloni zesintu kunye nezigcina-ntloko zentsimbi, iihempe zangaphantsi ezingangenwa bullet kunye nezigcina-ntloko ezinemicu ye-aramid eyongeziweyo azikho zincinci kwaye zikhaphukhaphu kuphela kodwa zisebenza ngakumbi nge-40% kwiimbumbulu.
Umgaqo osebenzayo wee-bulletproof vests unokuqondwa ngolu hlobo: xa ibhulethi ibetha umaleko welaphu le-vesti, ukothuka kunye noxinzelelo lwamaza ziveliswa malunga nendawo yempembelelo. La maza ngokusasazwa okukhawulezayo kunye nokusasazwa kwefayibha, ayakwazi ukuqubha kwinani elikhulu lemicu, aze ke abe kwindawo enkulu ukufunxa amandla omothuko. Kolu kufunxa ngamandla okuluthomalalisa ngempumelelo ifuthe leembumbulu emzimbeni womntu, ngaloo ndlela kuqatshelwa isiphumo sokhuseleko see-bulletproof vests.
Imathiriyeli yeBulletproof kunye nokusebenza kwayo okugqwesileyo
Undoqo weevesti ze-bulletproof ulele kwimathiriyeli yefayibha eyomelele kakhulu abayisebenzisayo, apho i-para-aramid fibers, eyaziwa ngokuba yi-para-aromatic polyamide fibers, ihlonitshwa kakhulu. Ubume bayo beekhemikhali ezilinganayo kakhulu bunika ikhonkco lemolekyuli ubungqongqo obugqwesileyo, buyenza yahluke kakhulu kwiipolymers eziqhelekileyo eziguquguqukayo ngokwemigaqo yokunyibilika, iipropathi zerheological, kunye nokusetyenzwa.
Iifayibha zePara-aramid ziyaziwa ngeempawu zazo ezibalaseleyo zomzimba kunye noomatshini, kubandakanya amandla aphezulu, imodulus ephezulu, kunye nobunzima. Amandla abo athile aphindwe kahlanu ukuya kwamathandathu aphezulu kunocingo oluqhelekileyo lwentsimbi, kwaye imodyuli yabo ethile idlula i-wire wire nge-factor of two to three. Ukongeza, iifibers zibonisa iipropathi ezibalaseleyo zobushushu, ezinokumelana nobushushu obuphezulu, ukwanda okuphantsi, kunye ne-thermal conductivity ephantsi, kwaye ayitshisi okanye inyibilike. Iintsinga zePara-aramid zikwabizwa ngokuba “ziintsinga ze-bulletproof” ngenxa yokugquma kakuhle kwazo, ukuxhathisa umhlwa, kunye nokungagugi.
Izicelo kunye neZibonelelo zePara-IFayibha yeAramid
Ifayibha yePara-aramid, eyona nto iphambili kushishino lwezokhuselo nomkhosi, isetyenziswa kakhulu kwihlabathi liphela. Ngokwezibalo, umlinganiselo we-aramid kwimicu yokukhusela e-US ingaphezulu kwe-50% kunye ne-10% eJapan. Iimpawu zayo ezikhaphukhaphu zenza ii-aramid bulletproof vests kunye nezigcina-ntloko, ezinokuphucula kakhulu amandla omkhosi wokusabela ngokukhawuleza. Ukongeza, i-para-aramid isetyenziswa kakhulu kwiimoto, kunxibelelwano, kwi-aerospace, kunye nemidlalo yangaphandle ngenxa yokusebenza kwayo kakuhle.
